Case for Sustainable Intensification through Irrigation: More food whilst maintaining ecosystems

Irrigation & Positive Ecosystem Services

• Mitigate droughts and floods• Stabilize river flows• Reduce silt loads• Recharge aquifers• Reduce Erosion

Irrigation & Negative Ecosystem Services

• Loss of environmental flows • Destruction of natural habitats & wet lands• Waterborne diseases - Malaria• Water logging & Salinisation• Groundwater mining

Activity Clusters in Irrigated Systems SRP

• Enhancing Success of Irrigation in SSA

• Revitalizing public irrigation systems

• Water Management in Eastern Gangetic Basin

• Managing salt–water balance in Indus and Central Asian irrigation systemsPhoto: Tom Van Cakenberghe/IWMI

Enhancing Success of Irrigation in Sub Saharan Africa

• Research Needs Assessment Workshop held in Addis (Feb 04-06, 2013)• Objective: Identify technical, policy and institutional research needs to

enhance success of irrigated Agriculture in SSA. • Participants

– Countries: Burkina Faso, Ethiopia, Ghana, Kenya, Mozambique, Niger, Nigeria, South Africa, Tanzania and Zambia.

– WLE partners: Africa Rice, FAO, ICRAF, ICRISAT, IFPRI, IWMI– AROs: CSIRO, UNL, UEA, KCL, Regional Universities– Africa Union, CADP, FARA,– Private Sector: Illovo.

• Nine Research Concepts identified.• Each are being developed into concept notes• The first to develop a framework for evaluation is funded with W1W2

funding.

Concepts Identified

• Southern Africa– Success and failure of public smallholder schemes– Smallholder agribusiness partnership– Private irrigation —appropriate technologies and financing

• West Africa– PPP– Technical issues– Enabling environment

• East Africa– Water use for sustainable use with u/s, d/s linkages– Value chain Analysis

Public Canal Irrigation Systems• E-Discussion in Jul/September 2012

• A half a day workshop in Dec 2012

• Thrust Areas:

• Irrigation System Bureaucracy , Change Management, Capacity Building, Performance

• Cost Recovery for O&M – Phase 1 funded with W1W2

• Irrigation System Performance

• Drivers

• Changes to SLOs

• Adequacy, Equity and Reliability of Water for ET.

• WLE Partners: FAO in Asia

Salinity

• Discussion paper being developed• Focus on Managing Salinity

– Farm Level interventions – ICARDA– Regional Interventions – IWMI

• Likely to be of new institutional models to minimize negative externalities

• Business models to bring saline areas back into production

• Minimizing areas and drainage volumes – SBC, SEB

Water Management in EGP

• Availability: – The Ganges Water Machine– How to test the hypothesis and what are the policy implications?

• Access: – Assessing potential and challenges of groundwater irrigation in EGP– Managing the energy-irrigation nexus

• Achievement– Quantifying Variation in productivity– Identifying reasons for variation in productivity– What are the policy implication?

• Workshop in May 2013

How to make CRP a reality?

• Leveraging W3 projects• Most projects are single center oriented. Mechanism to

talk to other centers unclear. • How will WG’s interact with SRPs• Limitations to scaling out
