Full Project Title: Enhancing rainwater and nutrient use efficiency for improved crop productivity, farm income and rural livelihoods in the Volta Basin (PN05)

Introduction

In the Volta River Basin, the food security of the population comprising mostly small-scale farmers who rely on rain-fed agriculture for their livelihoods is threatened by low water availability, increasing soil degradation and poor soil fertility.

The erratic variability and distribution of rain over the growing season and the frequent periods of drought within the copping season adds to livelihood risks by causing significant crop damage.

The project aimed at integrating water use efficiency, soil and nutrient management, and improved germplasm in a systems approach to address the major constraints in agricultural and water productivity of rain-fed agriculture with a focus on marketing, policy and participatory approaches to empower poor farmers.

Research Highlights

Research highlights

  • The research evaluated and adapted best bet technologies that improved water and nutrient use efficiencies and increase crop productivity in partnership with farmers.
  • The research used the Decision Support System for Agricultural Technology Transfer (DSSAT) to analyze the effect of mineral fertilizer in sorghum cultivation in two management systems, and train project partners in its use.
  • The warrantage or inventory credit system tested with the farmers for warehousing of farm products allows farmers to benefit from micro-credits.
  • The findings highlighted that a) the technologies (varieties and fertilizers) are adapted to the agro-climatic conditions, which ensures good yields; the technical/field protocols do not constitute a constraint to the adoption of technologies; sharing of seeds at the community level constitutes a major driver for the increase in agricultural production and larger-scale dissemination.
Project Outcomes

Project outcomes

  • In Burkina Faso and Ghana, the project has been able to stimulate and strengthen farmer-based associations and community-based organizations to collaborate with researchers and other stakeholders. Strengthening the research-extension-farmer linkages provided a good foundation for enhancing the adoption of new and promising technologies.
  • Strategic alliances established between key stakeholders including NGOs, government staff, extension units, farmers’ organizations, private sector and other research organizations to promote ‘best bet’ crop, water, and nutrient management strategies for scaling up and out most promising technical, marketing and policy approaches.
