Balancing Long and Short Term Agricultural Water Security
Investments: Promoting Market-Driven Small-Scale Technologies Parallel to
Large-Scale Water InfrastructureDouglas J. Merrey

Main Message
Large-scale water investments for agriculture and other purposes are important but take years before they provide benefits
They will therefore not contribute directly to 2015 MDGsIn parallel, policy reforms and modest targeted
public investments to encourage a micro-water management industry and market support system will provide large returns, contribute significantly to reducing poverty in a shorter time frame
And enhance the future benefits of infrastructure when it comes on stream
Outline
1. Briefly, the case for large-scale water infrastructure (Grey and Sadoff)
2. Micro-water management: Evidence showing benefits (treadle pump example)
3. Why have micro-water management technologies not scaled up?
4. Recommendations for the way forward
1. Water Security: The Case for Infrastructure Investments
“Sink or Swim? Water security for growth and development,” David Grey and Claudia Sadoff, Water Policy 2007Excellent article making the case for renewed
investments on water infrastructure, especially in Africa
Briefly present their argument, as it makes the case for the Conference Theme: “Accelerating Water Security for Socio-Economic Development of Africa”
I have some reservations, but for this presentation accept the validity of their argument
“Water Security” ‘Acceptable’ quantity and quality of water for life
and ecosystems with ‘acceptable’ level of water-related risks
Necessary condition for economic growthWealthy countries ‘harnessed hydrology’—most in
easy conditionsPoor countries faced with “difficult hydrology”
“direct consequence” – Have not achieved water security Some “hampered by hydrology” Some even worse off—”hostage to hydrology”
Bleak prognosis unless huge investments made to achieve “minimum platform” of water security

2. Micro-water management: Evidence showing benefits
Sources of evidence1. IWMI survey—SADC countries of “Micro-
Agricultural Water Management” (Micro-AWM) experiences
2. Case studies treadle pumps: Malawi, Ghana, Mali, Zambia, Kenya, Tanzania
3. Work in Asia (especially India)4. Several studies on drip irrigation kit experiences in
Zimbabwe (counter-factual)5. Work by Sokoine Agriculture University, SWMnet,
IMAWESA project, etc.Although mostly case studies, evidence for
following is compelling
“Agricultural Water Management” (AWM)
AWM – technologies, practices to capture, store or drain water, lift and transport it, and apply it to crops in the fieldContinuum ‘formal’ irrigation “micro-AWM”
[drip, treadle pumps] capturing and managing water in “rainfed” fields [rainwater harvesting, conservation agriculture]
Use “treadle pump” example here, but argument applies to a large menu of small individualized technologies

Micro-AWM--a “best bet” investment
Low-cost small-scale technologies and practices are promising investments:Relatively low cost per household can benefit more
people/$Rapid impacts: minimal gestation period Individualized—lower transaction costs than communal
or government irrigationLend themselves to being promoted through markets,
and to being targeted, e.g., to women, or poor Not a panacea, but high potential intervention
if done right, in the right circumstances
Treadle Pumps—Malawi Study
Impact study comparing 50 adopters and non-adopters in 2 districts, Malawi (Mangisoni 2006; 2008 forthcoming)Adopters have significantly higher productivity
& incomes, better food security, ability to improve lives; created employment
Non-adopters (using water cans)—poorer, with higher risk of falling deeper into poverty
Consistent with results in other East and West African countries
• Ghana study from IWMI similar results
• Recent study by FANRPAN in Zambia—significant impacts on poverty (Merrey et al. 2008)
• Kickstart in Tanzania and Kenya report significant contributions to economic growth (www.kickstart.org)
From Treadle to Motorized Pumps
Irrigating eggplant with motorized pump purchased with profits from treadle pump—Zambia (A. Daka)—a route to prosperity
If micro-AWM so good, why have they not reached any scale in SSA?
Main problem is restrictive and variable government policies (Merrey & Sally, forthcoming in Water Policy, 2008)Compounded by small national markets in most SSA
countriesMostly NGO-driven; these tend to be supply-driven
limited-time projects, often for relief Often import technology; no local support system for spare
parts, replacement, scaling up Examples show quality manufacturing is possible in SSA but
firms face many impediments
Inconsistent, Unsupportive Policies
No SSA country has a long-term supportive policy framework for encouraging a local market-driven industry (manufacture, sales, after-sales service, etc)
Inconsistent policies: duties on imports; subsidized imports and distribution through MPs under projects
High costs (2-5 X Indian price), no long-term investment
Small national input & output markets, and poor market access for sale of produce
Recommendations: Way Forward
National LevelWith stakeholders, develop consistent long term
supportive policies & designate a lead agencySupport for local R&D, social marketing, low-cost
loansLimited-time “smart” subsidies to kickstart the
industry, focused on small farmersTarget women, households who have labor and land but
need help with capitalUse input vouchers as a way of subsidizing through the
marketsBuild into overall long-term agricultural and water
resources development policies
Recommendations: Way Forward
Regional Economic Communities
As part of moving to freer trade, support development of regional markets for small-scale low-cost technologies for economies of scale
Support exchange of experiences among countries
Recommendations: Way Forward
Development Banks, DonorsActively support policy reformProvide financial support to encourage
development of African industries in micro-AWM technologiesR&D by local (not foreign) private firms, research
institutions“Smart subsidies”Low-cost loans for manufacturers, retailers“Social marketing” to popularize technologies
(Kickstart is a good example)

Final WordSupporting development
of an African market-driven micro-AWM industry can contribute directly to reducing poverty and hunger by 2015 while through synergies, enhancing the returns to large-scale water infrastructure investments.
Let us not miss the opportunity!
