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

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

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)
