Researchers seek low-cost way to reduce water infiltration. Plastic sheeting is currently being field tested by local gardeners to evaluate its effectiveness at reducing infiltration losses. However, high-quality plastic sheeting that resists high temperatures and extreme exposure to sunlight is both relatively expensive and difficult to obtain locally. For this reason, the project plans to research lower-cost materials that are available locally, such as traditional clay blocks. Simple drip irrigation systems will be tested as well, especially for sites where the water table is relatively deeper and pumping costs are higher.
Exports hold promise for the future.
Niger is a country with both a small population and a large potential for increasing its irrigated fruit and vegetable production. Due to its low per capita income, substantial increases in production could lead to saturation of the local produce market. For this reason, raising crops for export will play a key role in the country's future economy. Niger is already a major exporter of onions to other West African countries. Further market research is needed to identify products for which Niger has a comparative market advantage in the subregion.
