Irrigation master plan in Guinea

Development of a portfolio to provide an assessment of the situation and give guidelines for investment

DRAFTING OF A (NATIONAL) MASTER PLAN FOR THE DEVELOPMENT OF IRRIGATED AGRICULTURE & DEVELOPMENT OF A PORTFOLIO OF DETAILED STUDIES AND THEIR ASSOCIATED TENDER DOCUMENTS

As part of the Support Programme for the Agricultural Sector in Guinea, SHER, an Artelia subsidiary, has drawn up a master plan for the development of irrigated agriculture covering around 6,500 ha, using both a national and a multidisciplinary approach.

Based on an exhaustive inventory of land available for development (plains and lowlands), this document draws up a costed action plan in line with the country’s major national objectives, strategic guidelines and short-, medium- and long-term investment plan.

CONTEXT & ISSUES

PASA-G is part of the Guinean government’s strategy to develop modern, sustainable, productive and competitive agriculture, able to ensure both food self-sufficiency for the population and export revenues. The country has favourable rainfall and a large amount of arable land, only a small part of which is cultivated and irrigated.

The first action of the programme was to draw up an inventory of the country’s irrigation potential by collecting and analysing various data ( site investigation, satellite images) which fed into a national geographic information system (GIS) (250,000 km²). Subsequently, studies were carried out specifically on irrigated areas, combining various topographical (6,500 ha), hydrological, pedological, environmental and agro-socio-economic data. This work enabled preliminary development projects to be drawn up for 38 sites (6,107 ha). To meet the needs of the project, training was also provided for the staff of the Rural Engineering Department.
