Major problems facing the world today• Climate change and global warming (global CO2 emissions totalled 34 billion tons in 2011 (JRC/EC
2012), 50% above those in 1990) • Deterioration and exploitation of the natural resources • Air pollution, water pollution, soil contamination, soil erosion and degradation of arable land, forest,
and coastland• Habitat destruction (destruction in the rain forest to melting glaciers in the Arctic)• Global biodiversity declines (the rate of species loss is greater now than at any time in human history)• Natural resource scarcity and energy, food and water shortages• Frequent nature catastrophes• Uncontrolled disposal of urban and rural waste
• Increasing population, urban expansion, rural-urban migration• Poverty (925 million people are undernourished, FAO 2010)• Water and sanitation crisis (nearly 900 million people do not have access to clean drinking water, 2.5
billion lack access to safe sanitation facilities, UN 2010)• High unemployment rates among young adults• Wars• Ignorance, racism and discrimination• Corruption, increasing crimes• Pandemics and health care
• Crooked distribution of the world wealth and resources• Failed bankers advising failed regulators on how to save failed assets (Paul Hawken, 2009) • Speculation on food prices• Short-term planning • Improper management in a fast changing world

Some simple facts about Resources- Human beings are resource dependent, but most of our
resources are finite and non-renewable. - Earth resources are not equally distributed around the world.- Many of the resources, such as minerals, develop very slowly
throughout hundreds of millions of years. - If resources are not used in a sustainable way they will be
depleted, leaving future generations barren and empty handed.
- Every person has the right to an equal share of Earth's limited ecological capacity. And those who consume beyond their fair share accumulate an ecological debt to those who don’t.
- At present, human beings are inappropriately managing their resources by achieving a short-term benefit while causing pollution and degradation to the environment.
Hany El Kateb, Institute of Silviculture, TUM 10
Either or?
“At present we are stealing the future, selling it in the present, and calling it gross domestic product. We can just as easily have an economy that is based on healing the future instead of stealing it. We can either create assets for the future or take the assets ofthe future. One is called restoration and the other exploitation. And whenever we exploit the earth we exploit people and cause untold suffering.”Paul Hawken (2009), University of Portland
Hany El Kateb, Institute of Silviculture, TUM 11
How can we combat our problems?
• Knowledge, practical knowledge • Expertise and proficiency• Ability to communicate the vision
• Innovative approaches • Proper techniques to development
- By utilising the appropriate knowledge and technology currently available to us, we can solve many of the problems the world is facing today through the proper use, and use of potential, of the available resources in a sustainable way.
- By Brains, many brains
Hany El Kateb, Institute of Silviculture, TUM 12
Resource-based development
- enhancing the public awareness of the importance of the natural resources for the survival of the present and future generations, as well as the awareness of disasters that ensue following the misuse of resources leading to thirst, hunger, poverty and natural catastrophes,
- strict saving in the use of resources as it is the first measure to proper resource utilisation,
- rational utilisation of the natural resources including reuse and recycling,- finding the best alternative measures to reach sustainability in resource
utilisation,- establishment of policies and programmes for the rehabilitation, conservation
and, whenever necessary, preservation of the natural resources, - integration of sustainable management systems of the resources into the law, - further development of effective mechanisms for regulation, control and
monitoring of resource utilisation” (El Kateb, 2012).
“The political, economic, and social development must be closely associated with the sustainable management of available resources and should be based on:

Nature show us the best examples for the sustainable resource management. Nature manages itself in a sustainable way in diverse ecosystems.An ecosystem is almost self-sufficient and self-regulatory and is characterised by high stability in terms of resistance and resilience.Nature follows a strategy based on retaining the quality of the physical environment and the biodiversity of the flora and fauna, while maintaining the production by managing the energy, water, and nutrient cycles.We should study and understand Nature. Having the appropriate knowledge and technology, we can imitate Nature, solving many of our man-made problems.

Sustainable cities and green buildings in desert lands of Egypt
Hany El Kateb, Institute of Silviculture, TUM 24
The new cities must be well-planed, attractive, have charming architecture and should be designed to maximise the use of the available physical environment and at the same time minimise the use of supplementary energy and promote the use of renewable energy.
The cities should conserve the resources instead of wasting them and they should be producing instead of only consuming.
The cities should include all services and facilities that make daily life easy and enjoyable for each individual.
The population living in a city should be below the carrying capacity that is maximum number of individuals that a land area can satisfy their food, shelter, social requirements and movement in a short time, even without using vehicles.

Afforestation in arid regions
Hany El Kateb, Institute of Silviculture, TUM 36
What is Afforestation?Afforestation is the planting of trees on lands formerly used for purposes other than forestry. It is a cost-effective tool to reduce emission. Planting large areas of new forests is effective to slow the increase in atmospheric carbon dioxide.
Hany El Kateb, Institute of Silviculture, TUM 37
Arid lands and subtropical deserts- Arid lands cover an area of nearly one third of the earth's
land surface, where over one third of the world's population lives.
- The largest two subtropical deserts are the Sahara (9.1 million km2) in Northern Africa and the Arabian Desert (2.3 million km2) in the Arabian Peninsula.
- Subtropical deserts offer plenty of unutilised lands.- Subtropical deserts are characterised by low annual
precipitation, but on the other hand, they provide possibilitiesfor trees to grow all-year round and they receive sufficient sunlight, which is essential for the plant growth. Up to a certain extent, the more sunlight available for a plant, the higher the photosynthetic ability and thus the tree production.
Hany El Kateb, Institute of Silviculture, TUM 38
Arid lands and water- Insufficiency of water in many of the arid regions is a serious
constraint for human welfare and economic development.- Wherever people live, wastewater is generated form
municipal, industrial and agricultural activities. - Unutilised wastewater represents serious hazards for the
human health and environment and in addition is a waste of valuable water resources.
- Wastewater from municipal activities or sewage water can be preliminary treated and then used in providing the required water to irrigate trees. In addition, sewage water has high content of the primary plant nutrients "nitrogen" and "phosphorus", which are also essential for tree growth. Furthermore, sludge or solid waste remains after the wastewater treatment can be used for the production of renewable energy (e.g., Biogas) and soil conditioner.

Forestry in EgyptEgypt has almost no natural forests. We can find:
Relic of nature woodlands on the slopes of Gebel Elba (Mountain Elba) in the Elba Protected Area in the southern of the country, the largest protected area in Egypt (over 36,000 km2). www.cultnat.orgwww.cultnat.org
Sparse, scattered mangroves along the red sea coast.
Hany El Kateb, Institute of Silviculture, TUM 43
Forestry in Egypt (continued)
Many excavations in various parts of the country support the opinion that large parts of ancient Egypt at both Nile banks were forest zones.Also the Sinai Peninsula with its many valleys was rich in forest. The names of the valleys are still good indication.
Hany El Kateb, Institute of Silviculture, TUM 44
Forestry in Egypt (continued)
At the end of the first millennium, over a thousand years ago during the Fatimids era, Egypt was the first country in the world, which established a national forest organisation (Goldmann, 2001). Usage of wood was well managed. Wood was mainly used for the construction of cargo ships. Thousands of ships of a size of about 85m long and 35m abeam were built.
Today, far less than 0.1% (around 720 km2) of the country’s land area is covered with trees.

Hany El Kateb, Institute of Silviculture, TUM 45
Forestry in Egypt (continued)
A few indigenous species occur over the country. These include: sycamore, Acacia (was extensively used in ship building), tamarisk, Carob (was used in making furniture and luxury items), popular, mulberry-trees and above all date-palms as well as various fruit trees.
Forestry in Egypt is mainly based on plantation forests with the most common species being: Casuarina spp. and Eucalyptus spp.
Hany El Kateb, Institute of Silviculture, TUM 46
Egyptian National Programme for Afforestation In the mid 90s, the “National Programme for the Safe Use
of Treated Sewage Water for Afforestation*” was launched to mainly improve the prevailing environmental situation by
- making use of unutilised sewage water, which is a hazard for the human health and environment and in addition a waste of water resource and nutrients, in
- establishing forest plantations “greening desert lands” to support the efforts exerted to stabilise the greenhouse gas concentrations in the atmosphere.
Within the frame of this programme, a pilot project on over 4,000 hectares spread over the country was conducted to determine the success/failure of afforestation using basic-treated sewage water.

Multi-functionality of the afforestation in Egypt Decreasing pollution as growing trees absorb carbon dioxide from the
atmosphere. Protection against desertification, sand dune fixation, erosion prevention,
and coastal protection. Efficient use of the scarce water resources. Wood production and biofuel-crop production, as a renewable energy
source. Human settlement protection from wind and sand encroachment. Food security for an increasing population through combating desertification
and protection of arable and new reclaimed lands from wind. Afforestation in desert lands can be employed to protect cultivated areas (e.g., for food production). This leads to considerable reduction in environmental stresses (reducing plant damage by frost, sand deposit and insects, improving the efficiency of irrigation and fertilisation, conserve moisture in plants and soil) and improvement of the microclimate, thus, achieving higher yield of the protected crops.
Creating new jobs and qualification opportunities. Establishing new forest-based and related industries, which will help in
promoting employment and national economic development. Offering recreational opportunities in arid regions.

Opportunity for large scale afforestation in Egypt
- sewage water (about 7 billion m3 annually, of whichapproximately 40% is only treated) and
- desert lands of nearly one million km2.
Resources
Using 5.5 billion m3 sewage water for the afforestation and assuming an average annual water requirement of 8,500 m3/ha
- 650 thousand ha in the desert lands can be afforested(nearly 20% of the total agriculture area) and
- 25 million tons of CO2 annually can be stored.
Potential
Large-scale afforestation may stimulate cloud formation and may result in rainfall (University of Hohenheim 2012) that the country urgently needs.
Hany El Kateb, Institute of Silviculture, TUM 61
Large-scale afforestation
We assume that the average annual water-consumptionfor forest lands in Egypt = 8.500 m3 ha-1
Current annual volume of sewage water (7 109 m3) andindustrial wastewater (2 109 m3) in Egypt = 9 109 m3
If 5.5 109 m3
is used for afforestation, we can, theoretically, afforest an area of a size of 5.5 109 m3/8.500 m3 ha-1 ≈ 0.65 106 ha = 6.500 km2
and annually store CO2 of ≈ 25 106 tons
Expected volume of sewage water in 2017 = 17.0 109 m3
Using this volume, we can afforest an area of a size of17.0 109 m3/8.500 m3 ha-1 ≈ 2.0 106 ha = 20.000 km2
and annually store CO2 of ≈ 77 106 tons
