  1. José Yunis, Country Representative in Colombia for TNC Thomas Walschburger, Lead Scientist NASCA region, TNC Patricia Tellez, Lead Hydrologist NASCA region, TNC Magdalena River: preventing with development by design the loss of biodiversity, fisheries and water servicesCBD Nagoya, Japan, October 20, 2010

  2. Conserving at a watershed scale Set priorities based on biodiversity portfolio, set ecological limits of hydrologic alteration (environmental flows) Understand other sector needs and plans Negotiate so watershed ecosystems can be protected in the long run with a broader vision

  3. Magdalena´s Watershed 24% of Colombian Territory 32.5 million people living in the area 77% total population and 80% country´s GDP 7.100 m3/s in 273.459 Km2 5th most important watershed in South America (flows) 50% endemic fish species Collapse in fisheries, from 80.000 tons fish catch a year to 8.000 ton/year in the last 15 years Out of 200.000 total tons of fish catch/year (combined marine and freshwater), 80.000 came from Magdalena´s watershed

  4. Key variables and threats to freshwater ecosystems Dams, Intensive Agriculture Habitat loss: (mining, consolidación de bancos) sedimentation, Deforestation Agriculture, Urban sewage, waste, Mining Deforestation, Habitat losses near lake and rivers Dams, Dikes, Infrastructure Overfishing, Invasive/exotic species

  5. Hydrological Regime Environmental flows needed by ecosystems and species 2000 Feeding Habitats Flooded forest 1600 Eclosion Riparian habitats for feeding grounds Adult migration 1200 Flujo agua 800 400 0 4/1/2008 4/8/2008 5/6/2008 6/3/2008 7/1/2008 7/8/2008 8/5/2008 9/2/2008 9/9/2008 4/15/2008 4/22/2008 4/29/2008 5/13/2008 5/20/2008 5/27/2008 6/10/2008 6/17/2008 6/24/2008 7/15/2008 7/22/2008 7/29/2008 8/12/2008 8/19/2008 8/26/2008 9/16/2008

  6. After Before Alteración Hidrológica

  7. Flows Flows Regulated Dam flows Time Time Environmental Flows • High productivity • Superficial, low speed of water • Floodplain vegetation Loss of connectivity High Productivity High productivity reduced area River Lagoon

  8. Where to protect, Freshwater Portfolio

  9. 1 2 3 4 5 Classification of watersheds according to sizes Clase 1. entre 100 y 1.000 km2 (466) Clase 2. entre 1000 y 10.000 km2 ( 33) Clase 3. entre 10.000 y 100.000 km2 (5) Clase 4. entre 100.000 y 1.000.000 km2 (1) Clase 5. mayor a 1.000.000 km2

  10. Classification according to biophisiycal properties: (climate, geology, geomorphology, hidrology) 150 tipos de ecosistemas diferentes

  11. Área Activa de Inundación y Planos inundable

  12. FRESHWATER CONSERVATION PORTFOLIO 50 PRIORITY BIODIVERSITY SITES WERE IDENTIFIED IN MAGDALENA´S WATERSHED TO BE PROTECTED

  13. Límits for sustainability at a watershed scale with a new dam Habitats for eggs Migrations Fishing grounds Floodplains

  14. Spawning habitat Headwater habitat Existing dam Floodplain fishery Proposed dam Priority conservation river segment Hydropower Plan Conservation Plan

  15. Lack of integrated planning.. race to the bottom

  16. Existing dam Proposed dam Priority conservation river segment Compare Scenarios Hydropower Plan Conservation Plan

  17. Priority conservation river segment Cascadesame energy Existing dam Modify downstream dam operations Proposed dam Cross-compare scenarios Locate additional dams in already developed segment and eliminate conflicting dam Locate areas of conflict -Similar ecosystem values -Similar hydropower outputs
