Global Drivers - Andes Presentation

  1. 1. Drivers in the Andes Bert De Bievre, Miguel Saravia, Luis Acosta Chiang Mai, september 2011
  2. 2. Relevantconditions in Andes
  3. 3. Important drivers in Andes
  4. 4. Important drivers in Andes (1)Urbanization: drastic increase in urban population, ruralpopulation more or less stable. Causes geographicalconcentration of water demand Source: Presentation “Water Management and Climate Change”, by Axel Dourojeanni, Lima 2010. Source: Estrategia Andina para GIRH, CAN 2010.
  5. 5. Important drivers in Andes (2)Free trade agreements boost agroindustry for export, but largedifferences between countries
  6. 6. Important drivers in Andes (3)Land degradation: loss of regulation capacity in mountaincatchments Source: Wouter Buytaert, 2010.

  11. 11. Highlightingsome Responses in Andes
  12. 12. Responses (1) Urbanization: focus on catchments supplying water to large cities (e.g. water funds), campaigning for reduction of demand, large infrastructure to bring in water from further away.
  13. 13. Responses (2) Agroindustry: Interest for catchment, very recent (!), especially Peru Example: Design of PES in Rio Cañete basin
  14. 14. Responses (3) Land degradation: conservation of critical ecosystems (paramo, puna wetlands), in lower areas little response
  15. 15. Responses (4) Climate change: adaptation actions Whole lot of projects, governmental at national and local scale, and non-governmental Nothing really new:  Integrated Water Resources Management  Integrated Catchment Management  Typically reforestation with low positive hydrological impact or even negative impact
  16. 16. Responses (5) From Payment for Environmental Services to Benefit Sharing:  Inventory shows that few cases in Andes meet criteria to be Payment for Environmental Services  Large variety of Benefit Sharing Mechanisms  Strong resistance to PES in countries like Ecuador and Bolivia, now almost forbidden by law
