Summary

The climatic conditions in the Sahel region offer a great potential for decentral solar-based systems to provide clean energy for enhancing electrification and support water supply for domestic use and irrigation – urgently needed especially in rural areas of the region in order to achieve energy, water and food security. The project will conceive, establish and operate a solar-based energy hub at a secondary school in the Dosso region of Niger. Major objective of the research is to optimize the use of clean energy in a holistic way for improving livelihood in a village through access to electricity and pumping groundwater for drinking and irrigation purpose. Applying a transdisciplinary approach, the optimization aims at providing technically functional, economically feasible and ecologically sustainable solutions meeting the requirements of the local population. The energy hub will be installed close to a secondary school in order to reach the majority of rural population and gain the involvement of young generation as ‘agents of change’. Building on advanced water supply by solar pumping, ZEF’s contribution to the collaborative project is focusing on enhancing irrigation scheduling and handling of techniques for improving water productivity under current and future climatic conditions.

Methodology

Major steps of our approach consist of:

- assessing the performance of small-scale irrigation in terms of appropriateness, efficiency and productivity

- deriving options towards improving irrigation performance by advancing irrigation schedules, irrigation techniques and their handling

- integrating improved irrigation schedules and techniques into the agricultural production system considering the socio-economic, institutional and environmental context.

The research is comparing a drip irrigation system which is supplied by groundwater from solar-driven pumping and operated according to advanced irrigation scheduling procedures with the conventional irrigation practice (reference situation) in a village in the Dosso region in Niger. Field work will cover dry (full irrigation) and rainy (supplemental irrigation) seasons and will be used as an entry-point to cooperate with farmers as ‘end-users’ to ease the implementation of modified irrigation practices.
