Colombia Cauca Valley Water Fund, Colombia Water fund investments TNC-ecosystem service payments to fund conservation Prioritize investments

Water For Life Water Fund

Maintain consistent water flows necessary for drinking water, biodiversity and agriculture through a coordinated strategy. Committee: Watershed Associations Sugar Cane Associations The Nature Conservancy Vallenpaz (local NGO) Water For Life Water Fund

Linea Base Boundary Scenarios - CIAT No Water Fund Current Landscape Degraded Forest Water Paramo Deciduous Forest Pasture Wooded pasture Mixed agriculture Sugar cane Rangeland Suburban Mines Urban With Water Fund

No Water Fund With Water Fund Change Annual Water Yield (mm/yr) Annual Erosion (tons/ha/yr) Demonstration Scenarios - CIAT

Priority Areas for Investment

Stable Erosion Decreased Yield

Priority Areas for Investment Stable Erosion Decreased Yield Improved Erosion Greatest Improved Yield

Identify priority investments: – realistic scenarios for each basin – biodiversity portfolio – climate change Make investments! – Monitor and iterate Next Steps

Science-policy links strong Science gaps – Impacts of alternative management actions on services and biodiversity – Simple sub-annual water yield model that differentiates surface and groundwater Capacity – Committee relying on outside expertise and technical capacity Lessons

Colombia Cesar Department, Colombia Permitting and Licensing Ministry expanding requirements to include biodiversity and ecosystem services Demonstrate approach with coal mining sector

Services of interest: Water quality (Tier 1 nutrients and sediment) Water yield (groundwater and surface) Cesar Department, Colombia

Current Landscape Demonstration Case Scenarios 12,000 km 2 Permits Granted Permits RequestedAll Permit Blocks

Beneficiaries 12,000 km 2 Permits GrantedPermits RequestedAll Permit Blocks

Areas that provide the same service to the same people Service Sheds

Change in sediment export (t/ha/yr) Erosion Impact Permits GrantedPermits RequestedAll Permit Blocks

Rank Per Area Total Impact Rank By Total Impact Permit blocks ranked by erosion and nutrient pollution per unit area

6 mines can be offset to same beneficiaries with no ratio Permits with Potential for Mitigation

More Aggressive Restoration Conservation priority areas for restoration

Define mitigation ratio Summarize impacts and options Present framework to Ministry and train technical team Next Steps

Science-policy links strong Science gaps – Simple water yield model that differentiates surface and groundwater – Data availability (aquifers, retention rates) Capacity – Will train Ministry staff (sustainable?) Lessons

How InVEST can help policy What InVEST can help: Identify/map key ES regions with simplified procedure and fewer data. Provide spatial/visualized results for government agencies’ decision-making. In an effort to further increase the benefits of these measures, with the help of GEF/UNEP, the GOC plans to implement an Ecosystem Function Conservation Areas (EFCAs) program both in regional scale and local scale.

Background As part of its efforts to reduce floods in the Yangtze River basin, The Government of China (GOC) is implementing a series of soil and vegetation conservation programs in the upper Yangtze River basin. Natural Forest Protection Projects Grain for Green Project Shelter Forest System Project

Background--Overview of Baoxing County 210 km to chengdu 3114 sq km Population 50,000 multinational pla ce

Baoxing Landuse Types Forest land : 69.2% Native grass: 20.6% Crop land : 2.32% Town and residential:0.78%

Biodiversity Red panda Davidia involucrata Musk deer chinese monal Giant panda 429 species of vertebrates, including 17 first-class protected, 51 second-class protected 3,000 plants among which 8 species have been listed as National First Class Protected Species (I), 20 as National Second Class (II)

How InVEST can help policy County government situation Sustainable Master planning Payment for Ecosystem service, especially for Yaoji hydropower station, carbon salling Tourism/infrastructure/mining development planning GEF project background – demo site for local scale EFCA CCICED task force – case study

Ecosystem service Model A : Water yield Error: 4.4% with the observed data. Results were varying with the Parameter of Zhang_cte Default: Input: 4.433

Ecosystem service Model B : Water Retention Error :11.3% with the observed base flow from Nov to March.

Ecosystem service Model C : Soil Retention Result of model: t/sq km, Observed data: t/ sq km Modification: use different equation for LS factor in different slope. Threshold: 30% For low slope<30%: For high slope>30%: Sheet erosion Gully erosion

Ecosystem service Model D : Pollution control less pollution in Baoxing Add precipitation layer or through flow layer

Ecosystem service Model E : Biodiversity Data prepare: threat source including cropland, roads, mine The result is agree with our knowledge about baoxing species and habitat size and location should be take in account

Ecosystem service Model F : Carbon Hard to get the current and future harvest rate Soil carbon data only related with soil types not with land use types

Ecosystem service Model G : Pollination
