Published on

Presented by Jennie Barron of the Swedish University of Agricultural Sciences at an event hosted by The Swedish International Development Cooperation Agency (SIDA) on March 19th, 2018. The event was "Water for Agenda 2030 - balancing the needs for food, water and energy in a changing climate" was organized in celebration of Water Day.

  9. 9. 2. An SDG nexus opportunity: The case of spontaneous smallholder irrigation development in SSA
  10. 10. Smallholder farming and irrigation: A vibrant and growing sector • Smallholder farmers are critical for local and national food security in SSA and SA • Smallholder farmers increasingly initiating and financing small-scale land and water management technologies themselves, e.g.: • In India > 50% of the irrigated area watered by smallholder pumps • In much of Africa, smallholder AWM reaches more farmers than public irrigation. Farmers’ reliance on different types of irrigation in Ghana
  11. 11. Small-scale dry season irrigation can benefit many Water quantity? Water quality? CO2 emissions?
  12. 12. Finding technology options that are solutions
  13. 13. Case: Solar pumps to support micro-irrigation (off-grid, Ethiopia) The context and opportunity • Mostly rainfed, smallholder farming • 14% of population connected to the electricity grid • Significant potential for solar pumps (~7 M ha) to offer climate smart, supplemental irrigation • Demand is high; traction with public and donor supported programs. • Potential business scenarios for positive returns on investment The challenges • Regulatory: difficult to access information/incentives • Value chain: underdeveloped for irrigation/solar energy • Rural financing: low capacity, limited access • Capacity: limited on technology installation and repairs
  14. 14. The context and opportunity • Communal reservoirs are common in the region • Provide water when natural streams dry up • Irrigating areas from 0.01-374ha (Volta basin) • Multi-purpose water use • Access: directly from reservoir or shallow wells near the reservoir, limited access through gravity irrigation The challenges • Water availability: soil erosion upstream fills reservoirs with sediments; downstream water availability • Water application is still labor intensive, gravity irrigation systems favor female farmers • Aging infrastructure: most constructed 80-90s Case: Small reservoirs infrastructure(Burkina Faso) Small reservoir, monthly distribution of use (Bagyalgo, Burkina Faso)
  15. 15. 3. R4D in food-water-energy nexus to meet SDGs Joel 20xx
  16. 16. Do we have more nexus opportunities to address SDGs? • Water management (incl. irrigation) in sustainable intensification of agriculture can address multiple SDG targets • Water reuse and waste management in rural –urban (circular) economy for agriculture and other use • Water management in agriculture essential to meet ecosystems targets
  17. 17. Challenges when moving from ‘silver bullets’ to complex solutions? Systems approach for solutions demand multiple actors and disciplines: • Human, institution capacity to analyse and develop • Innovations, data and technology • Levelled market and policy arena • Wise (=best informed) investments form public private and IFIs
