Titre : Supporting investment decisions in water and land management across the rural-urban continuum in the Volta - Niger focal region

Région /Pays : West Africa (Burkina Faso, Ghana)
Lieu (x) : Volta-Niger region

Date  : June 01, 2014 — December 01, 2016

Descriptif
A number of agricultural water management (AWM) and resource recovery & reuse (RRR) solutions for improved agricultural productivity have been proposed and technically verified in the Volta-Niger region, especially in Ghana and Burkina Faso. However, their effectiveness in terms of multiple ecosystem services delivery, environmental health, adoption factors and returns on investment (RoI) are largely unknown and the potential of some interventions might be over- or undervalued. Therefore, this project will assess the effectiveness, adoptability and returns on investment (RoI) of some of these solutions, using ecosystems approach, to draw lessons and recommendations for their scaling up and business feasibility potential. Selected interventions target improvement in water and/or land productivity through agricultural intensification across the rural-urban as well as the rainfed-irrigation continuum. Four specific interventions have been selected for analysis : (1) Small water infrastructure (SWI) for small holder irrigation ; (2 Drip irrigation ; (3) Safe and productive water reuse ; and (4) Nutrient and organic matter recovery from waste.

Our general approach will be multi-disciplinary and ecosystem-based where multiple ecosystem services will be examined. The project will produce investment guides and policy briefs to be used by the next users listed above. Investment guides help promote efficient and effective interventions that restore the environment, increase agricultural productivity, and food security. Policy briefs focused on gender and equity issues influence policy makers in gender and equity related decision-making process. The project will involve about 12 graduate students from our partner universities thereby contributing to regional capacity building.
