Use of In. VEST fits within a stakeholder driven decision process In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 8
EXAMPLE APPLICATION Inputs to economic models Direct impact on utility/welfare Avoided costs (increased efficiency) Change in “downstream” production function Clean water Soil quality Pollination Pests/diseases Non-timber forest products etc. In.

SPATIALLY EXPLICIT ROUTING • Uses digital elevation model (DEM) results to understand how nutrients and sediments move across the landscape. In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 12
INVEST USER INTERFACE • Simple enough for researchers or conservation planners to run on their own. In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 13
IMPACTS MEASURED AT MULTIPLE SCALES – 1. ) Household/farm-level: • Who exactly are the providers and beneficiaries of the services? – 2. )The agricultural sector • What is the impact of ecosystem services on increasing sustainable agriculture yields? In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 14
IMPACTS MEASURED AT MULTIPLE SCALES – 3. ) Economy-wide, in order to explore tradeoffs and complementarities between productivity, nutrition and ecosystem services • Where there are conflicts between conservation and agriculture, how can they be optimized? In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 15
CONNECTIONS TO ECONOMICS SPATIALLY EXPLICIT UNDERSTANDING • Example: GTAP – In. VEST provides high resolution spatial results – Expands analysis based on agro-ecological zones • Example: “Land-use change impacts on ecosystem services, ” (Lawler et al. 2014) • Incorporation into dynamic calculable general equilibrium models • Transparent accounting of non-marketed values – Effect on downstream or future users In. VEST: Integrated Valuation of Ecosystem Services and Tradeoffs 16
CONCLUSION • In. VEST provides spatially explicit production function and ecosystem service models that can act as inputs to bioeconomic models. • Enables analysis of risks and tradeoffs in conservation and agriculture • Helps describe value to humans in non-marketed ecosystem services In.
