An Approach for the Sustainable Governance
of Rural-Urban-Linkages
Urban NEXUS

increase of 180.000 people / d in metropolitan regions of DC:
increasing rural-urban linkage of people, goods, resources, capital...
increasing urbanization of rural lands, of lifestyle and consumption.
hence, increase in resource consumption / cap contrasting resource availability
rise in water consumption: supply shortfall, wastewater pollution vs lack of re-use, storm water and flooding events, climate stress
emerging peak energy: exploitation of biomass energy sources, deforestation, health and air quality inflictions, increase in energy prices
levelling off of food production: under/ malnourishment spreading worldwide
Urbanisation: the world has become a city
Seite ‹Nr.›
Growing Metropolitan Regions
governance of multi(pli)city
in population numbers: city core vs. metropolitan area
in subnational government mandates: local, district, province, region…
administrative functions: decentralised vs. deconcentrated
in spatial functions and patterns: dense centers vs. vast rural lands
governance challenges
shift away from simplified models of rural and urban livelihoods
rural-urban dynamics, dependencies, resource conflicts and –crisis
resource-waste due to inefficiencies, lack of mandate, inadequate
technology.
a matter of governance
- rural-urban as well as city-city linkages
- inter-sectoral and inter-governmental resource management

+2.5bn People
90% of Growth in Africa and
Asia
Long Supply Chains
Ressource Scarcity

potential NEXUS - Initiatives support of sustainable rural-urban linkages
safeguard of ecosystem services, protected areas and biodiversity, improvement of microclimates
decentralised energy mgt forstering renewables, clean air and protecting local forests
interregional mobility mgt for connectivity, less congestion
integrated watershed management and provision of water on an energy-efficient and safe basis
optimizing water and energy use in local food production, reuse of organic waste and wastewater for urban farming
urban and peri-urban land and investment management
closed-cycle resource management: reduce, recover, recycle
green urban economy approaches:
green public standards, procurement , incentives
fostering of green infrastructure and (public) buildings

Sectoral combinations
• Waste-to-energy (increasingly common practice)
• Eco-districts
• Eco-sanitation (waste-energy-food)
• W-E-F: Water-energy-land efficiency in agriculture (UPA)
• Water-energy, e.g. district heating/cooling
Innovations:
• Biodiversity-waste-energy
• Cross-sectoral approaches to integrating informal/marginalized settlements
• Waste-social inclusion, e.g. through urban mobility
Funding, implementation, and partnership models
No single formula for success, various models used, e.g.:
• Public-private partnerships
• Multi/bi-lateral development aid projects
• Non-profits / CBOs
• Local government services / utilities
• Bi-lateral (national government) collaborations

Waste recycling, processing and marketing
• Localised recycling of bio waste
Busses fueled with biogas produced from the city‘s own organic waste

Nashik, India - Local Energy-Water-Agriculture-Land Nexus
• Resource constraints:
groundwater depletion; high energy use for water treatment and
distribution; decreasing available land for cultivation.
• Objectives / Benefits:
reducing inefficiencies, activating idle land, promoting (peri)urban
agriculture
• Pilot interventions:
(i) Agriculture Pump Sets, efficiency & performance evaluation
(ii) Mapping biogas potential in the pilot area
(iii) Creating potential groundwater recharging system
(iv) Promoting agro-tourism/ agro-education in schools

Sector Project Urban NEXUS Initiative: PILOT PROJECTS - 2013-2014
Kinondoni Municipality, Dar es Salaam, Tanzania
Two primary schools as demonstration sites:
• Resource constraints:
low quality food, inefficient wood stove cooking, flooding,
open waste disposal
• Objectives / Benefits:
involvement of various municipal departments; improved
learning environment for students; educating community
through children; upscaling onto public facilities
• Interventions:
Rainwater harvesting, sanitation, vertical food gardens,
energy efficiency (cooking)
