Abstract
This chapter examines the international legal regime on land degradation. It first provides
a brief overview of land degradation as a complex environmental issue around the world
before discussing the causes and effects of land degradation. It then analyses a variety of
legal responses to land degradation, from global initiatives such as the Convention to
Combat Desertification, the Convention on Biological Diversity, the United Nations
Framework Convention on Climate Change, and the IUCN Covenant on Environment and
Development; regional initiatives such as the World Soil Charter 2014 and the UN
Sustainable Development Goals 2015; and national laws and policies. The chapter also
explores some of the main elements that need to be taken into consideration when
designing legislation to address land degradation, including land tenure, access to land,
farming systems and land use, the role of protected areas, and physical planning.

21.1 Overview
Land degradation is one of the most complex environmental issues facing national
governments and communities worldwide. It is also one of the least understood. Land and
its primary constituent element, the soil, form the basic terrestrial foundation of human
development and survival, physically sustaining societies around the world
through agriculture, grazing, forestry, and the maintenance of water sources. The
human links to land and its soils are an inherent part of global and national culture
and heritage.2 Soil bodies are large and readily identifiable ecosystems and are the
fundamental components of terrestrial biodiversity.3
Until recently, land degradation law was seen as the poor cousin of natural resources
and environmental law. However, with some 33 per cent of the world’s arable land being
2 Soil as part of the heritage was recognized for example in debates on the Soil Conservation Act 1938 of New South
Wales, Australia: ‘Men who waste land, or how unnecessarily destroy timber, destroy something that is the heritage
of the nation, and they should be allowed to do so no longer’, Bill McKell, quoted in T. Bonyhady and T. Griffiths,

lost to soil erosion or pollution in the last forty years,4 there is now an increasing
concentration on the law and policy relating to land degradation and its links to food
security and associated human rights. Further, as soils are the second largest reservoir of
carbon after the world’s oceans, their importance as natural carbon sinks, as well as by
release of carbon to the atmosphere through unsustainable agriculture and
grazing practices, means that land degradation is becoming a significant factor in
global5 and regional climate change policy.6
Most states do not have adequate legislation to address the broad range of processes
involved in land degradation. Particular areas of law directly or indirectly attempt to
prevent or control land degradation and to promote sustainable land use. These include soil
conservation law, contaminated land law, planning law, protected areas law, forest law,
water law, desertification law, biodiversity law, and in some jurisdictions, customary laws
relating to Indigenous peoples and local communities. Several global initiatives have been
important in establishing international rules which, when transposed to the national level,
can be directed towards the control and prevention of land degradation. The most
prominent of the multilateral instruments relating to land degradation control in arid, semi-
arid, and dry sub-humid areas is the United Nations Convention to Combat Desertification
in Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa.7
While calls for an international instrument addressing land degradation beyond the realm
of desertification have been made since the early 2000s, progress on developing such a
regime has been slow.8 On the other hand, several regional treaties contain provisions to
control or prevent land degradation.
This chapter first paints a broad canvas of land degradation law at international level,
sketching the developments of this field in the past few decades, and then delves into legal
regimes at regional and national level.
21.1 Causes and Effects of Land Degradation
Land degradation is a process in which the state of the biophysical environment is affected
by a combination of natural and human-induced processes acting upon the land.9 The more

9 More specifically, Art. (1(f) UNCCD defines ‘land degradation’ as: ‘. . . the reduction or loss, in arid, semi-arid and dry
sub-humid areas, of the biological or economic productivity and complexity of rain-fed cropland, irrigated cropland,
or range, pasture, forest and woodlands resulting from land uses or from a process or combination of processes,
including processes arising from human activities and habitation patterns, such as: (i) soil erosion caused by wind
and/or water; (ii) deterioration of the physical, chemical and biological or economic properties of soil; and (iii) long-
term loss of natural vegetation’.

degraded land becomes, the less it can ecologically support. This can cause degradation to
accelerate, as plants and animals that would normally play a part in restoring the soil are
unable to survive. Agricultural practices are a common cause of land degradation.
Overworking the soil can degrade it, sometimes permanently. A stark example of land
degradation can be seen in the infamous 1930s United States Dust Bowl droughts, when
large-scale topsoil loss occurred as a result of a combination of intensive agriculture and
drought conditions.10 This stimulated the enactment of the first US Farm Bill and
subsequent soil conservation legislation.11
On a global scale, accelerated wind and water soil erosion are the principal land
degradation processes. Current estimates of the area of degraded land worldwide vary from
1 billion to 6 billion hectares.12 The critical drivers are seen to be: agriculture and forestry;
urbanization; infrastructure development; energy production; and mining and quarrying.13
The UNCCD Global Land Outlook 2017 observes:
Direct drivers are either natural (e.g., earthquakes, landslides, drought,
floods) or anthropogenic (i.e., human-induced); some of the latter influence
what would formerly be thought of as natural climatic events. Human-
induced drivers such as deforestation, wetland drainage, overgrazing,
unsustainable land use practices, and the expansion of agricultural,
industrial, and urban areas (i.e. land use change) continue to be the most
significant proximate cause of land degradation.14
The more recent phenomenon of the purchase or lease of productive agricultural lands in
poorer countries by richer countries, often known as ‘land-grabbing’ is of increasing
concern.15 The practice can undermine sustainable livelihoods and economic development

15 Major investors now see land in foreign countries as an attractive asset. Over the last decade, they have bought or
leased large areas, especially in developing countries, for farming, mining, tourism, and other uses. Governments
generally welcome the influx of funds in the hope that they will stimulate the economy. However, such land
acquisitions are often seen as controversial; see e.g. FAO (2015) Status of the World’s Soils, at:

as well as the capacities of societies and individual nations. They can result in degradation
of land and contribute to lower levels of human well-being and higher levels of
vulnerability, deprivation, and disadvantage. Oguamanam argues that ‘land grabs are not
sensitive to the socio-ecological agency of land in rural communities in
developing countries that are targets of land grabbing. In Madagascar,
Mozambique, Ethiopia, Uganda, Cambodia, Indonesia, Colombia, Brazil, and elsewhere,
land grabs have resulted in the displacement or forced relocation of millions of
culturally diverse indigenous and local communities from their ancestral lands. These
displacements violate communities’ subsistence and self-determination rights and
disrupt their environmentally sustainable stewardship practices.’16 He goes on to argue
that ‘land-use practices associated with land-grabbing threaten the biological and
cultural diversity that represents integral aspects of sustainable agriculture, and by
extension, sustainable development.’17
The human rights aspect of land-grabbing was a focus of the Tirana Declaration
of 2011, which denounced ‘all forms of land grabbing . . . ’, defining large-scale
land grabbing, inter alia, as acquisitions or concessions that ‘in violation of human
rights, particularly the equal rights of women’.18
Further issues involve the involuntary migration and displacement of people
and communities from productive lands into marginal ecological and economic areas
because of ethnic and religious conflict and associated deprivation and violence.19
With respect to the forest sector, the ‘main cause of land degradation in forest
ecosystems is selective logging of commercially valuable trees’.20 This industry has
caused severe soil erosion and loss of biodiversity in many of the world’s forests,
especially in Southeast Asia where the density of commercially valuable timber species
is high. Other causes are forest fires; by removing surface vegetation, excessive
runoff can result. In addition, mining can entail removal of non-timber forest products,
and cause soil and water pollution. The Center for International Forestry Research states:
Deforestation and degradation can impact heavily on small communities who are
dependent on forests as a source of emergency income and food during famine or
economic hardship. Deforestation also permanently destroys valuable plant and
wildlife species within a forest. A degraded forest may not be able to support
specialized species. Excessive clearing or thinning of forests can destabilize the
world’s climate by releasing into the atmosphere millions of tons of greenhouse gasses
normally stored in wood in the form of carbon. This can damage the atmosphere and
It also indicates that ‘in the period 2000–2011 around 200 million hectares changed hands with the average size of
land deals around 40,000 hectares’.

contributes to global warming and climate change. By storing carbon, forests provide
a major environmental benefit by reducing global warming. In most cases, people
clear tropical forests to cultivate land. This is motivated by many factors. These
include the prospect of generating greater income through farming, changes in land
rights, tenure, subsidies, tax laws, resettlement projects, new or restored roads,
population pressures and corruption.21
The link between unsustainable forestry and land degradation has been long recognized.
Significantly, the 1992 Statement of Forest Principles22 noted that:
[E]fforts to maintain and increase forest cover and forest productivity
should be undertaken in ecologically, economically and socially sound
ways through the rehabilitation, reforestation and re-establishment of trees
and forests on unproductive, degraded and deforested lands, as well as
through the management of existing forest resources.23
Improving human well-being by protecting soil from degradation has thus become a moral
imperative and a critical aspect of human rights in recent years, particularly from the point
of view of food security.24 Concern about world hunger and food security has stimulated
the appointment by the United Nations of a Special Rapporteur on the Right to Food,25 and
is also a significant focus of the 2015 UN Sustainable Development Goals.26
The process of restoring land that has become degraded is known as remediation. 27 In
some cases, land is too badly degraded for remediation to be effective, forcing communities

that relied on the land to relocate in order to access new resources. This in turn can
contribute to population pressures in other fragile environments, ultimately repeating the
land degradation cycle all over again. The aim of land degradation laws and policies is to
neutralize this cycle, and then to encourage the processes that enhance the soil.
21.3 Legal Responses to Land Degradation
21.3.1 Global Initiatives
21.3.1.1 Introduction
Land degradation is a cross-cutting issue. It intersects with the conservation of biodiversity,
the causes and effects of climate change, the transport and disposal of hazardous wastes,
and the incidence of contaminated lands. It is also relevant to the capacity of various states
and regions to sustain their human populations and to guarantee food security. In recent
years there has been an increasing interest in examining and understanding the law relating
to land degradation and the promotion of sustainable land use, with more determined
moves to promote reform in this area of environmental law at an international level.28 Some
progress has also been made on developing appropriate frameworks for sustainable
management of land at the national level.
Land degradation first gained broad international attention at the 1992 Earth Summit.
Agenda 21devoted a chapter to ‘Managing Fragile Ecosystems: Combating Desertification
and Drought’.29 The Earth Summit’s three international conventions each have a land
protection role, with provisions that could be used to promote sustainable land use,
although the provisions are generally tangential to the particular needs of soil. They are the
1994 Convention to Combat Desertification in Countries Experiencing Serious Drought
and/or Desertification, Particularly in Africa30 (UNCCD), the 1992 United Nations
Convention on Biological Diversity (CBD)31 and, to a lesser extent, the 1995 United
Nations Framework Convention on Climate Change (UNFCCC).32 The UNCCD
specifically links these three instruments in its Preamble: ‘Bearing also in mind the
contribution that combating desertification can make to achieving the objectives of the
United Nations Framework Convention on Climate Change, the Convention on Biological
Diversity and other related environmental conventions.’33 In addition, the Rio Declaration

on Environment and Development,34 and the Non-legally Binding Statement of Forest
Principles35contain important principles for land degradation control and prevention.
21.3.1.2 The UNCCD
The definition of ‘desertification’ under the UNCCD acknowledges that land degradation
in arid, semi-arid, and dry sub-humid areas of the world results from various factors,
including climatic variations and human activities (Article 1). The UNCCD acknowledges
that arid, semi-arid, and dry sub-humid areas together account for a significant proportion
of the earth’s land area and form the habitat and source of livelihood for a large proportion
of its population. The objective of the Convention is to prevent and reduce land
degradation, rehabilitate partly degraded land, and reclaim desertified land, particularly in
countries that experience serious drought. However, the UNCCD cannot be considered an
adequate instrument for the protection and sustainable use of soil as such because its
provisions do not adequately recognize soil bodies as ecosystems, nor does it contain other
elements to capture the full range of legal principles and processes to encourage protection
and sustainable management of soil. Further, the UNCCD’s geographic focus of
‘desertification’ to arid, semi-arid, and dry sub-humid areas under the UNCCD excludes
other climatic regions of the world that experience severe land degradation processes.
While the addition of annexes enables the UNCCD to be applied more specifically at
the regional level, taking into account different climatic and geographical conditions,36 the
annexes do not operate to extend the reach of the convention beyond arid, semi-arid, and
dry sub-humid areas in the regions. However, this is not to deny that those areas not
currently classified as ‘semi-arid and dry sub-humid’ within the regions could become so.
This appears to be contemplated by the UNCCD text, for example in the context of National
Action Programmes, by use of the phrase‘ drought prone areas’.37The Annexes to the
Convention use similar language: the Asian Annex includes the phrase ‘strengthen and/or
establish information, evaluation and follow up and early warning systems in regions prone
to desertification and drought’;38the Central and Eastern Europe Annex includes ‘the
variety of forms of land degradation in the different ecosystems of the region, including
the effects of drought and the risks of desertification in regions prone to soil erosion caused
by water and wind.’39 While an interpretation that broadens the scope of the Convention
has not been put forward explicitly by the UNCCD Secretariat, the use of such phrases, as
well as the continued recent use of the phrase‘ desertification/land degradation and
drought’ in documents arising from the Conferences of the Parties40 gives rise to that
possibility.41

21.3.1.3 The Convention on Biological Diversity
The objective of the CBD is relevant to land degradation as it includes the conservation of
biological diversity, encouraging the sustainable use of its components and the fair and
equitable sharing of the benefits arising out of the utilization of genetic resources, including
by access to genetic resources and by transfer of relevant technologies. It takes into account
various rights over those resources (Article 1). The CBD also recognizes that nations have
a responsibility for conserving their biological diversity and for using their biological
resources in a sustainable manner (preamble).
Fundamental to the CBD is the concern that biological diversity is being significantly
reduced by human activities. This obviously includes the processes of land degradation.
The avoidance of land degradation is implicit in the definition of ‘sustainable use’, defining
the term as ‘the use of components of biological diversity in a way and at a rate that does
not lead to the long-term decline of biological diversity, thereby maintaining its potential
to meet the needs and aspirations of present and future generations’ (Article 2). A feature
of the activities carried out under the auspices of the CBD is a focus on agricultural
biodiversity, with a strong interdependence being recognized between the two.42
The CBD and UNCCD Secretariats are actively developing a strategy for land
degradation in the context of biodiversity conservation entitled Framework and Guiding
Principles for a Land Degradation Indicator, as part of the effort to ‘monitor and report
on progress towards target 15.3 of the Sustainable Development Goals, the strategic
objectives of the Rio Conventions and other relevant targets and commitments’.43 It
recognizes that many countries do not have the capacity to monitor and report on land
degradation. The purpose of the Framework is ‘to provide consistent definitions and the
best available methodologies as well as global/regional data options for three sub-
indicators’.44 These include land cover and land cover change, land productivity, and
carbon stocks above and below ground ‘that could be used to derive the indicator for
monitoring and reporting progress towards SDG Target 15.3 as well as other relevant
targets and commitments.’45
It is contended here that for the CBD to take on an expanded, more precise role in
addressing land degradation and encouraging the sustainable use of land, it would be
desirable for technical guidelines to be drafted on sustainable land management, reinforced
by an extra protocol to the Convention.46Such provisions would desirably then be reflected
in legislation on land degradation and soil conservation at the national level.

The UNFCCC recognizes the role of terrestrial ecosystems as a sink and reservoir for
potential greenhouse gases and is concerned that human activities have been substantially
increasing the atmospheric concentrations of greenhouse gases.47 Two of the principal
sources of greenhouse gases are changes in land-use cover (e.g. forests) and land use (e.g.
cultivation). As noted above, soils are a major reservoir of the earth’s carbon, second only
to the oceans.48 The main land use activities that play a role in emissions of greenhouse
gases and initiate or exacerbate soil degradation are deforestation, biomass burning,
cultivation, using organic manure, applying nitrogenous fertilizers, and over-grazing of
livestock. Excessive vegetation clearance, a principal cause of land degradation, is one of
the key concerns of the UNFCCC. Land degradation exacerbates the emission of gases
from terrestrial and aquatic ecosystems to the atmosphere. The UNFCCC promotes
sustainable management, and the conservation and enhancement of sinks and reservoirs of
greenhouse gases not controlled by the Montreal Protocol, including biomass, forests, and
oceans as well as other terrestrial, coastal, and marine ecosystems. However, while its focus
is on the reduction in emissions in all sectors, it cannot be considered as a sufficiently
specific legal vehicle to address land degradation.49
The Kyoto Protocol50 under the UNFCCC, adopted in 1997, contains a responsibility
to promote sustainable forms of agriculture in the light of climate change considerations
(Article 2(a)(iii)). It recognized the need to expand and preserve soil carbon sinks and
improve agricultural practices in countries where a significant proportion of the emissions
are related to the clearing of vegetation for agriculture (Articles 3 and 5). The Marrakech
Accords provided rules for the implementation of the Protocol.51
The 2015 Paris Agreement under the UNFCCC deals with mitigation of greenhouse
gas emissions, adaptation, and finance.52 Its preamble recognizes ‘the importance of the
conservation and enhancement, as appropriate, of sinks and reservoirs of the greenhouse
gases referred to in the Convention’. This has important implications for land degradation
control. Under the Paris Agreement, each country determines plans and regularly reports
on the contribution it should make to mitigate global warming. There is no mechanism to
force a country to set a specific target by a particular date, but each target should go beyond
previously set targets, an approach that is now recognised as the principle of progression,53
as expressed in UNFCCC Article 3: ‘the efforts of all Parties will represent a progression
over time’. The aim of the Paris Agreement is to enhance the implementation of the

greenhouse gases . . . ’. 49 See further, I. D. Hannam, ‘International and National Aspects of a Legislative Framework to Manage Soil Carbon

UNFCCC through: ‘(a) Holding the increase in the global average temperature to well
below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase
to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the
risks and impacts of climate change and (b) Increasing the ability to adapt to the adverse
impacts of climate change and foster climate resilience and low greenhouse gas emissions
development, in a manner that does not threaten food production’ (Article 2).These actions
will likely include a wide range of national sustainable land management actions to control
or prevent land degradation, including limitations on forest clearing, and improving land
cover by employing conservation farming techniques and preventing overgrazing of
pastures.54
21.3.1.5 Land Degradation as a Common Concern of Humankind
Large-scale land degradation processes of wind and water erosion (or a combination of
both) can lead to significant transboundary problems affecting two or more countries,
necessitating cooperation between states.55Transboundary Natural Resources Management
(TNRM) has been defined by Griffin et al. as: ‘[A]ny process of cooperation across
boundaries that facilitates or improves the management of natural resources (to the benefit
of all parties in the area concerned)’.56Given the interdependence of many countries on
trade in food products to address their food security, the world itself can be regarded a
‘global farm’, making land degradation truly a matter of common global concern. For the
use, conservation and development of other natural resources, such as water (rivers, lakes,
and groundwater), as well as the air and the components of biodiversity, a wide range of
international and regional instruments have been agreed.The concepts of common heritage
of (hu)mankind as found in the UN Convention on the Law of the Sea,57 and common
concern of humankind, as seen in the CBD and UNFCCC, are used in respect of areas and
natural resources both within and beyond the national jurisdiction of any state.58 It is
notable, however, that the UNCCD does not use the phrase ‘common concern’ but refers
to desertification and drought as ‘problems of global dimension in that they affect all
regions of the world and that joint action of the international community is needed to
combat desertification and/or mitigate the effects of drought’. By regarding land
degradation as a common concern of humankind in the same way as in the CBD and

implications and opportunities for mitigation and adaptation (Rome: Food and Agriculture Organization of the United
Nations, 2009), see generally 5-11.
55 Reduction in water quality by soil erosion and sedimentation in transboundary watercourses can affect many countries;
likewise, soil particles from wind erosion can be deposited in countries that are great distances from their origin. Dust
from China is blown towards Korea, Japan, and the Pacific Ocean, and transport of dust has been demonstrated by
chemical and radiological analysis of dust in Hawaiian soil, Greenland ice cores, and St. Elias mountain in Canada; see

UNFCCC, a conceptual shift may be achieved to accord this issue the same weight as in
those two conventions.59
Bearing the above in mind, it makes sense for states sharing a common land system to
manage that system as a single ecological unit notwithstanding national boundaries, as has
been done in the European Union (EU) with respect to water resources.60 In fact, the
proposal for a European Soil Directive61 in 2006 contemplated such an approach:
Soil degradation in one Member State or region can have transboundary
consequences. Indeed, dams are blocked and infrastructure is damaged
downstream by sediments massively eroded in another country farther
upstream. Equally, groundwater bodies flowing through bordering nations
can be polluted by contaminated sites on one side of the border. Losses of
soil organic matter in one Member State can impair the achievement of the
Kyoto protocol targets by the Community. This would imply that the costs
to restore environmental quality are borne by a Member State different from
that where the soil degrading practice occurred.62
21.3.1.6 IUCN Covenant on Environment and Development
Finally, with respect to global initiatives, the provisions of the IUCN Covenant on
Environment and Development should be noted.63 The Covenant takes a holistic approach
to the protection of the environment and conservation of natural resources. The Covenant’s
commentary recognizes that protection and restoration of soils are essential to many natural
systems and resources, as well as to biological diversity’.64 Article 23 states:
Parties shall take all appropriate measures to ensure the conservation and
where necessary the regeneration of soils for living systems by taking
effective measures to prevent large-scale conversion and soil degradation
59 See B.W. Boer, ‘Land Degradation as a Common Concern of Humankind’ in F. Lenzerini and A. Vrdoljak (eds.),
International Law for Common Goods: Normative Perspectives on Human Rights, Culture and Nature (Oxford: Hart
Publishing, 2014), 289. 60 e.g. various Directives of the European Union aim to achieve a uniform approach to the use of natural resources, such
as Directive 2000/60/EC of the European Parliament and of the Council establishing a framework for Community
action in the field of water policy (EU Water Framework Directive). It provides for a river basin approach to water
management in the EU; see http://ec.europa.eu/environment/water/water-framework/info/intro_en.htm.

and loss, to combat desertification, to safeguard the processes of organic
decomposition and to promote the continuing fertility of soils.
21.3.2 Regional Initiatives
Attempts to address land degradation prior to the 1992 UN Conference on Environment
and Development were predominantly regional in nature, and did not establish specific
rules for sustainable land use.65 Only one of these is a specific soil instrument, made under
the 1991 Alpine Convention,66 namely the Protocol for the Implementation of the Alpine
Convention in the Field of Soil Protection.67 This is the only legally binding regional
instrument in the world specifically directed to the protection of soil. It aims ‘to reduce
quantitative and qualitative soil impairments, in particular by applying agricultural and
silvicultural production processes which have a minimal detrimental impact on the soil, by
using land economically, controlling erosion and restricting soil sealing’ (preamble).
Among its objectives it provides:
In particular, the ecological functions of soil, which are essential elements
of the ecological balance, shall be safeguarded and preserved both
qualitatively and quantitatively on a long-term basis. The restoration of
impaired soils shall be promoted.68
Markus suggests, with some reservations regarding regional socio-economic and political
conditions, that this Protocol could provide a model for an international soil conservation
regime.69
In the African region, the Revised African Convention on the Conservation of Nature
and Natural Resources,70 adopted in March 2017, includes specific mention of soil under
its definition of ‘natural resources’ (Article V 1). It is one of few regional treaties that plays
a significant role in addressing land degradation. Its objectives are to enhance
environmental protection, foster the conservation and sustainable use of natural resources,
and to harmonize and coordinate policies in these fields with a view to achieving
ecologically rational, economically sound, and socially acceptable development policies
and programs (Article II). These provisions are critical for the prevention and control of
land degradation. The parties are guided by three important principles that are relevant for
65 e.g. the 1968 African Convention for the Conservation of Nature and Natural Resources 1001 UNTS 4 (note that this
instrument was revised in 2017 to include land degradation); the 1974 Convention Establishing a Permanent Inter-
State Drought Control Committee for the Sahel; also Art. 7 1985 ASEAN Agreement on the Conservation of Nature
and Natural Resources (not in force), available at: http://sunsite.nus.edu.sg/apcel/kltreaty.html.
66 The 1991 Alpine Convention is focused on pursuing ‘a comprehensive policy for the preservation and protection of
the Alps by applying the principles of prevention, payment by the polluter (the ‘polluter pays’ principle) and
cooperation, after careful consideration of the interests of all the Alpine States, their Alpine regions and the European
Economic Community, and through the prudent and sustained use of resources . . . ’ (Art. 2(1)). The Convention
includes soil conservation under its ‘General Obligations’ in Art. 2(2)(d).

land degradation control, including: ‘the right of all peoples to a satisfactory environment
favorable to their development, the duty of States, individually and collectively to ensure
the enjoyment of the right to development, and the duty of States to ensure that
developmental and environmental needs are met in a sustainable, fair and equitable
manner’ (Article III).Article VI includes specific measures on land and soil:
1. The Parties shall take effective measures to prevent land degradation, and
to that effect shall develop long-term integrated strategies for the
conservation and sustainable management of land resources, including soil,
vegetation and related hydrological processes.
2. They shall in particular adopt measures for the conservation and
improvement of the soil, to, inter alia, combat its erosion and misuse as well
as the deterioration of its physical, chemical and biological or economic
properties.
Any new international or regional framework to guide national legal efforts to address land
degradation must, we contend, be based on a clear understanding of the confusing
differences in the use of terminology in the environmental law, land science, sociological
and ecological disciplines.71 A range of concepts and terms that appear in the instruments
outlined above can be used to underpin such a framework but careful attention should be
paid in the selection and explanation of its elements for possible adoption at national level.
21.3.3 Strategies and Policies
21.3.3.1 The World Soil Charter 2014
The non-legally binding Revised World Soil Charter of 2014 specifies that ‘[s]oils are a
key enabling resource, central to the creation of a host of goods and services integral to
ecosystems and human well-being. The maintenance or enhancement of global soil
resources is essential if humanity’s overarching need for food, water, and energy security
is to be met.’72 The Charter includes guidelines for actions by government, including to:
‘incorporate the principles and practices of sustainable soil management into policy
guidance and legislation at all levels of government, ideally leading to the development of
a national soil policy’.73

Degradation Neutrality

In 2015, the United Nations completed negotiations for the new UN Sustainable
Development Agenda.74 The seventeen Sustainable Development Goals (SDGs), which
form part of the 2030 Agenda came into effect in January 2016. Over the next fifteen years,
the SDGs are intended to mobilize efforts to end poverty, fight inequality, and address a
wide range of environmental issues, including climate change, conservation of the oceans,
desertification, land degradation, and the loss of biodiversity.75 Although the SDGs are not
legally binding, governments are expected to take ownership and establish national
frameworks to achieve the Goals and their associated Targets.
With regard to land degradation, the general aim of SDG 15 is to ‘conserve and restore
the use of terrestrial ecosystems such as forests, wetlands, drylands and mountains by
2020’. The UNCCD Global Land Outlook observes that ‘SDG 15 . . . puts a strong
emphasis on the need to scale up transformative management practices with the goal to
“Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage
forests, combat desertification, halt and reverse land degradation, and halt biodiversity
loss”’.76
Land degradation neutrality is seen as ‘a new paradigm in environmental politics for
Sustainable Development Goal (SDG) 15’.77SDG Target 15.3 ambitiously aims, by 2030,
‘to combat desertification, restore degraded land and soil, including land affected by
desertification, drought and floods, and strive to achieve a land-degradation neutral
world’.78 Knut Ehlers observes that this Target ‘thus mainstreams in the SDGs the concept
of a “land degradation neutral world” as a leitmotif for soil protection.’79 A 2016 Science-
Policy Brief defines Land Degradation Neutrality (LDN) as ‘a state whereby the amount
and quality of land resources necessary to support ecosystem functions and services and
enhance food security remain stable or increase within specified temporal and spatial scales
and ecosystems’.80 LDN is a new initiative intended to halt the ongoing loss of healthy land
through land degradation. Unlike past approaches, LDN creates a target for land
degradation management, promoting a two-pronged approach: to avoid or reduce
degradation of land combined with measures to reverse past degradation. The objective is

that losses are balanced by gains, to achieve a position of no net loss of healthy and
productive land.81
The UNCCD 2018–30 Strategic Framework82that emerged at COP 13 was described
as ‘a new global roadmap to address land degradation ’and ‘the most comprehensive global
commitment to achieve Land Degradation Neutrality (LDN) in order to restore the
productivity of vast swathes of degraded land, improve the livelihoods of more than 1.3
billion people, and to reduce the impacts of drought on vulnerable populations’.83 The
Strategic Framework includes a range of provisions with respect to policy and planning
and ‘actions on the ground’, but does not specifically include legal requirements to achieve
its objectives. The Ordos Declaration that was also issued at COP 13 committed to
facilitate, ‘for Parties that wish to do so, the voluntary land degradation neutrality target-
setting process, and to provide sufficient support to national efforts to turn defined land
degradation neutrality targets into effective projects and equitable action’.84 The challenge
is to translate Goal 15 and Target 3, together with the aims of the Strategic Framework into
implementable legislation and policies that will deliver LDN at a national level in all
countries suffering from land degradation.
21.3.4 National Laws and Policies
21.3.4.1 Introduction
As noted in the introduction to this chapter, most countries do not have specific legislation
to address land degradation. In 2002, the authors observed:
Only a few States have a law that refers to the ecological features or needs
of soil, or its role in the conservation of biological diversity. Many
individual laws do not have a clear statement of purpose or objectives, and
in other cases, the stated intention of the legislation is poorly reflected in
the substantive provisions of the legislation. Some States have developed a
framework of legislation to manage a number of distinct soil and land use
problems, but they generally lack a linking or coordinating mechanism.85
In the ensuing sixteen years, with some exceptions, the position is not very different.
However, with the increasing attention now begin given to land degradation through the
concept of LDN, it might be expected that more states will enact specific legislation.86 The

Policy 2016, at 3; T. Qin and F. Dong, ‘Legislative Progress and Soil Contamination Prevention and Control in China’
17
following section briefly summarizes some of the main elements that need to be considered
when designing legislation to address land degradation.
21.3.4.2 Land Tenure
Land tenure systems in many regions tend to be dynamic, responding to socio-economic
and political changes put in place for the exploitation of natural resources. Secure land
tenure is seen as an important part of sustainable land management.87 As recognized by
FAO, ‘[L]and tenure and environmental conditions are closely related: land tenure can
promote land use practice that harms the environment or it can serve to enhance the
environment’.88 As noted by the FAO, ‘[i]n many parts of the world, clearing the land has
become an effective way to lay claim to it. For example, forests have traditionally been
used for slash-and-burn agriculture by local people who had customary rights to those
resources,’89 and ‘lack of clear rights can reduce the incentive to implement long-term
resource measures, which leads to land degradation’.90 This observation is reinforced by
the 2017 Global Land Outlook: ‘Many developing countries lack adequate laws, or fail to
implement established provisions that legally determine who owns the land and its
resources.’91
The types of land tenure in place for a particular jurisdiction often determine the kinds
of uses to which land can be put.92 It can be used as a conservation tool through zoning of
uses that specify what can and cannot be done on the land, with specific protections for
soils, water, flora, and fauna being attached to the zoning. Such mechanisms can be
significant for controlling or preventing land degradation and promoting sustainable land
use.93 The different categories of land tenure will determine who uses the land and how the
land is managed, which in turn can determine the type, degree and extent of land
degradation. Land tenure is categorized by the UN Food and Agriculture Organization as
private, communal, open access, or state land tenure.94 The Global Land Outlook uses a

Soil Protection in Mongolia’ in Ginzky et al., International Yearbook of Soil Law and Policy 2016, at 285; M.

Soil Degradation’) note that ‘there has been some legislative development at federal and state level in the United
States’; see also Du Qun and I.D Hannam, Law, Policy and Dryland Ecosystems in the People’s Republic of China

society, e.g. common grazing rights, private residential and agricultural holdings, and state ownership of forests.

slightly broader categorization: nationalized; freehold; leasehold; rental; cooperative; and
customary land tenure.95
21.3.4.3 Access to Land
Several strategies exist to gain access to land which can directly, or indirectly, affect the
environmental condition of the land. These include:
• Purchase.
• Adverse possession or prescription; the acquisition of rights through possession for
a prescribed.96
• Leasing, or gaining access to land by paying rent to the owner.
• Sharecropping, or gaining access to land in return for paying the owner a percentage
of the production.
• Inheritance or gaining access to land as an heir.
• Squatting illegally on land.97
In addition to these strategies, land access can be enabled by land reform.98 Land
reform necessarily involves the reworking of laws and regulations regarding land
ownership as well as a revisiting of customary tenure systems. Such land reforms usually
occur in situations where much of the land is owned by a relatively small number of
landowners and the land is idle or under-utilized. Land restitution is also seen as an
important type of reform,99 as has redistribution.100 Such reforms necessarily involve legal
and institutional changes regarding ownership and use, and often can be politically
controversial. Concerning large-scale land redistribution, anti-reform arguments include
loss of productivity and lack of adequate compensation. Zimbabwe is an example of the
difficulties of such reforms, whereby land redistribution has contributed to economic
decline, environmental degradation and increased food insecurity.101
21.3.4.4 Farming Systems and Land Use
Farming, including agriculture, aquaculture, grazing, and forestry, use a significant
proportion of the world’s land, in order to provide the essential products for maintenance
of human life. Land also has intangible values, in terms of open space, cultural landscapes,
95 UNCCD, Global Land Outlook, at 81. 96 In some countries, this may be the only method for small farmers to gain formal access to vacant or abandoned land
and to bring it into productive use.

and aesthetics.102 States have varying legal and institutional systems that determine the
nature of the law and policy that govern agrarian land, and therefore, its role in sustainable
management of the land and avoidance of the occurrence of land degradation.103 Depending
on the particular economic and political systems involved, legal regulation can determine
whether landowners retain freedom in land use decision-making, or whether that freedom
is restricted. Farmers are in any case recognized as having ‘a dual indivisible role, the first
being that of an entrepreneur trying to maximize his/her benefits, the other being that of a
manager of public goods: the environment’.104
Farming systems cover a range of farm activities: cropping, livestock grazing, forestry
and woodlots, fisheries, including aquaculture, forestry, and poultry. The concept of
sustainable farming systems involves using the land without disrupting the ecological and
socio-economic balance. Historically, many farming systems, and especially cropping,
have been concentrated on maximizing yield, often leading to significant land degradation.
Globally, farming and pastoral land is paid most attention by the UNCCD through its
focus on semi-arid and drought-affected land.105 However, the CBD is also significant for
agriculture and pastoral land because it recognizes that nations have a responsibility for
conserving their biological diversity and for using their biological resources in a
sustainable manner.106 As noted above, the UNFCCC recognizes the role of terrestrial
ecosystems as sinks and reservoirs for potential greenhouse gases and that human activity
has been contributing to atmospheric concentrations of greenhouse gases.107 Laws
concerning protection of land are seen as important in keeping pastoral land productive.
They focus on soil productivity, prevention of erosion, and protecting land from
environmental damage.108 Typical examples are found in Australia, the United States and
Canada.109
21.4.4.5 The Role of Protected Areas
A protected area is defined by the CBD as ‘a geographically defined area which is
designated or regulated and managed to achieve specific conservation objectives’ (Article
2). A broader definition that has been widely accepted across regional and global
frameworks has been provided by the International Union for Conservation of Nature
(IUCN) in its categorization of guidelines for protected areas: ‘A protected area is a

clearly defined geographical space, recognised, dedicated and managed, through legal or
other effective means, to achieve the long term conservation of nature with associated
ecosystem services and cultural values’.110 The IUCN definition more specifically allows
for the conservation of protected areas with regard to their natural and cultural values. As
a result of the endeavours by national governments, the CBD Secretariat, the IUCN, and
related bodies, pursuant to ‘Aichi targets’ set at the 2010 CBD Conference of the Parties
in Nagoya, some 15 per cent of the world’s terrestrial areas within national jurisdiction are
declared as protected, with the highest regional percentages being found in Latin America
and the Caribbean.111
The legal protection of specific areas can occur at three levels. At the international
level, the World Heritage Convention112 and the Ramsar Convention on Wetlands,113 for
example, designate protected areas according to their definitions and listing criteria, with
nominations being prepared at national level.114 At regional level, the best example is the
European Natura 2000 programme.115 At national level, a large number of states have
enacted laws for protected areas, with varying levels of success.116 The range of natural
values that any one protected area may safeguard can be vast. Many will be allocated
primarily for species conservation, whether for flora or fauna or for the relationship
between them, but protected areas are similarly important for conserving sites of
Indigenous and local community cultural importance. They also represent considerable
reserves of natural resources, as well as the capacity to store carbon.117
21.4.4.6 Physical Planning to Avoid Land Degradation
In many countries, the protection of agricultural land against unsustainable practices is
addressed by physical planning and zoning legislation. Physical planning processes can
produce guidelines for land use at national, state/provincial, and local levels of government.
Physical planning regulations generally have binding effect through a system of zoning,
environmental impact assessment, and approvals for a wide range of both rural and urban
development activities, in order to avoid degradation and inappropriate use of land. In
jurisdictions that include Indigenous people, it is important to ensure their participation in
physical planning and decision-making, as many Indigenous cultures are based on
sustainable use of land resources. The provisions of the United Nations Declaration on the

117 As noted by Asner, ‘Measuring Carbon Emissions from Tropical Deforestation: An Overview’, carbon emissions
from tropical deforestation account for an estimated 20 per cent of global carbon emissions. Thus, in protecting the
world’s carbon stocks, greenhouse gas emissions are reduced and long-term land cover change can be minimized.

Rights of Indigenous People118 should be taken into account in this context, as recognized
in its preamble: ‘Recognizing that respect for indigenous knowledge, cultures and
traditional practices contributes to sustainable and equitable development and proper
management of the environment’.
21.4 Concluding Remarks
Despite the severity of land degradation worldwide, as outlined by the UNCCD’s Global
Land Outlook, in many countries the legislative framework to manage the different
processes of land degradation remains unable to effectively contribute to overcoming the
problems. The future challenges and opportunities for the management and restoration of
land resources in the context of sustainable development have been cited by the Global
Land Outlook as including: food, water and energy security; climate change and
biodiversity conservation; urban, peri-urban, and infrastructure development; land tenure,
governance; gender; migration, conflict, and human security.119
The recent development of the SDGs by the UN and the promotion of the concept of
Land Degradation Neutrality (LDN) as a primary objective in regard to SDG 15.3 have
shed new light on tackling the global problem of land degradation. Equally, new and
innovative legislative frameworks will be required as a component of the overall approach
to achieve LDN. Attaining LDN will significantly contribute to sustainable development
through rehabilitation, restoration, conservation, and sustainable management of land
resources. This integrated approach is the basis of the conceptual framework for LDN, a
target which is seen as the driving vehicle for the implementation of the UNCCD and as
an important part of the 2030 Agenda for Sustainable Development. It has been described
as a daunting challenge, where the ‘institutionalized international cooperation under the
umbrella of UNCCD needs more flesh and concrete actions in terms of scientific study,
concerted international legal mechanisms and policy responses at domestic level to make
it work on the ground’.120 In this regard, at the international level the negotiation of a new
global instrument,121with all the attendant difficulties of introducing yet another
convention, could fill a much-needed gap in providing legislative guidance for national
land degradation controls in those regions where the UNCCD applies, as well as more
generally.
This chapter has ranged over the international, regional, and national legal and policy
frameworks which are currently available to address land degradation. Those frameworks
are demonstrably fragmented, with insufficient connection horizontally between the
various relevant Conventions, as well as vertically between those Conventions and the
regional and national mechanisms. The international community continues to require a
global regime which recognizes the fundamental value of the lands and their soils around
the world, and that such a regime must include principles and concepts to form the basis
