Outline:
Climate – one more pressure in the MENA region
MENA: most water (and land) scarce, subject to severe resource degradation, e.g. desertification, groundwater depletion
climate projections largely agree on decrease in total precipitation, on top of increasing temperatures and more/stronger extremes
resource productivities remain low
GHG emissions are rising rapidly
with projected major impacts on water resources, agriculture and ecosystems
RCP 8.5
RCP 4.5

Climate – one more pressure in the MENA regionclimate change (like other pressures) can affect social stability
more severe and persistent drought after 2005 than ever before

more severe and persistent drought after 2005 than ever beforecontributed to migration to urban areas, increasing pressure and unrest
MENA: a case for a nexus approach
MENA: a case for a nexus approach
general principles:generating synergies, reducing negative externalities,increasing productivities across resources and sectorsand strengthening resilience
the nexus builds on established integrated approaches , such as:- ecosystem approaches (CBD), e.g. „natural infrastructure“- landscape approaches (World Bank), „improved landscape configuration“- multi-functional systems (IAASTD), e.g. reservoirs,
co-generation of energy and water…..
new: real integration across sectors from the beginning (different from IWRM), and: synthesis of experience, outscaling, transfer
How to do it – nexus solutions
e.g. soil and water conservation for improved green water productivity, reduced irrigation demandand climate resilience
climate-safe land use planningaccounting for change in precipitation, sea level rise etc.
adding energy to the equation (e.g. agricultural intensification)moving towards renewable energye.g. for water pumping or seawater desalination
„seeing is believing“ – making a nexus case at the farmers level
A nexus example from Lebanon
Solar power for irrigation in an organic farm in the Bekaa Valley
12 ha farm, requiring constant water supply for livestock, vegetables, and fruit
~ $50,000 annual electricity costs
frequent and severe power cuts required the farmer to rely on back up generators
switching irrigation system (which consumes most electricity) to solar power (installation cost approximately $76,000) makes the farm self-sustaining and profitable
A nexus example from Jordan
problem: rapid aquifer depletion for irrigation and urban demands
solar farming (photovoltaics) as income alternative for local farmers
reducing water demand and associated fossil fuel demand for pumping
increasing drought resilience
participatory process through Highland Water Forum
Solar energy farming in the Azraq Basin

Why doesn‘t it happen - institutional obstacles – an example from the Lebanon
Ministry of Energy and Water: national water sector strategy, e.g. identifying agricultural water use efficiency as priority area
Ministry of Agriculture: agriculture strategy doesn’t address water use efficiency
Lack of communication and coordination even within MoEW
Discrepancies between legal and de facto responsibilities among different institutions , e.g. due to embedded UNDP staff in key ministries – „shadow government“
Overlapping responsibilities among different institutions.
Lack of institutional memory in the political system
Institutional entry points
Strengthening bridging institutions e.g.:
- Ministry of Environment, including its climate change unit
- National Council of Environment (different ministries , academics and civil society represented
- Lebanese Center for Energy Conservation (LCEC)
- Lebanese Agriculture Research Institute (LARI),
Using opportunities such as revisions of water, agricultural, energy, climate and other strategies and action plansfor mainstreaming nexus principles,
Institutional (and economic) entry points
Raising interest by identifying economic benefits ( win-wins)and opportunities for equitable development of different regions and sectors
Capacity building to meet knowledge requirements under increasing complexity
Developing economic incentives for reducing negative externalities across resources, sectors and regions, e.g. payments for environmental services
