A process for resolving conflicts within water-food-energy systems stressed by climate change Group 4. The NCAR Nexuses
Clarify the decision context Define Objectives & Measures Create Alternatives Estimate Consequences of Alternatives Evaluate Trade Offs Among Alternatives Implement & Monitor Decision Support Framework: Structured Decision Making
California is in a Major Drought
Implications of Drought Less water rain during the growing season – higher demand for irrigation and pumping of ground water. Both of which require more energy and are expensive. Loss of Hydroelectric power production, which was 14% of total instate production in Power plants reduce production because water in lakes/rivers/estuaries too hot to be used for cooling. New player in the mix: Hydraulic fracturing. People in conflict
Water use by Sector 50% Environmental, 40% Agricultural, 10% urban. In areas where water is shared by all three sectors: 33% Environmental, 53% Agricultural, 14% Urban.
Population 2.75x Food production: 4.2x Rice 4x; Wheat 10x; Pulses+coarse: < 2x How was it achieved: Extensification agricultural land area Intensification of land cropped More fertilizers, better seeds, irrigation Trends in India:
Irrigation in India
The Problem in India (Gujarat and Punjab) 1. Unsustainable use of groundwater in agriculture in Gujarat, India (epicenter). - Danger of salt water contamination due to low water tables - Farmers continually need to dig deeper wells and buy more powerful pumps. 2. Financial burden of the state - Electricity is subsidized to farmers to pump up water. - The cost of pumping deep water can today be on the same order of magnitude as the farmers’ income. - With current policies agriculture is a net loss for the state of Gujarat. 3. Energy insecurity - Due to overuse of electricity for pumping water the power supply is, or may be in the future, subject to inferior reliability. Voltage fluctuations may damage motors and other equipment. - Situation expected to worsen in the future due to: Climate change Rising population 4. Land degradation from water erosion
System Identification (scoping process - what’s the situation? Who is involved?) System -Conduct analysis of current energy and water policies -Conduct analysis of local hydrology -Analyze how water and energy is used in the state today and how it is expected to be used in the future. -Study current climate and expected climate change Stakeholders Method: snowball method (cast a wide net. due diligence to include everyone) include social anthropologists Stakeholders in Gujarat are: - Government: Agriculture and Cooperation Department, Energy and Petrochemicals Department, Narmada and Water Resources‚ Water Supply and Kalpsar Department, Local community/governments - Non-government: Farmers, Agribusiness e.g. FieldFresh, Power companies, Owners/representatives from local factories

Extra Material The Question: Can we increase farmer incomes without further depleting (ideally maintaining constant) GW? Possible Approaches we want to Explore: 1.Incentive to reduce use; 2.Make farmer direct beneficiary of reduced water use 3.Provide information/measurement tools 4.Use historical Data as baseline of electricity 5.Compensate for “reduction” below baseline 6. Ensure revenue neutral scheme for govt.
What are the lessons, opportunities and challenges? Groundwater is precious –Priority for drinking -Use as a drought buffer, not as primary agricultural resource –Improve surface water storage, distribution Dramatic reform needed in agricultural sector –Energy/water pricing (could be dynamic based on conditions) –Crop selection and Market Access Seasonal Forecasts of Climate and Markets Optimization of area allocation and location per crop Government and Private Sector Procurement Supply Chain –Water Saving Technologies and Irrigation Practices Real Time Weather forecasts Yield Enhancement while reducing fertilizer, pesticide and energy use –Corporate-Public Extension Program in support of Supply Chain
