Abstract

THE MONITORING AND POSSIBLE FORECASTING OF AGRICULTURAL PRODUCTION ARE IMPORTANT ELEMENTS OF FOOD POLICY IN WEST AFRICAN COUNTRIES. THESE DATA ARE ALSO NECESSARY FOR PLANNING FOOD AID AT INTERNATIONAL LEVEL. THE GROUND OBSERVATION NETWORKS SUCH AS THAT OF THE AGRHYMET CENTRE, OF THE PERMANENT DIAGNOSIS OF THE CILSS OR OF THE NATIONAL AGRICULTURAL STATISTICS, CAN USEFULLY BE COMPLETED BY SATELLITE OBSERVATIONS. SPOT AND LANDSAT TM IMAGES CAN PROVIDE SUPPORT ELEMENTS IN A PROCEDURE OF STRATIFYING AGRICULTURAL LANDSCAPES AND SAMPLING CULTIVATED SURFACES. THE AVHRR APPROACH IS OF GREAT USE IN FOLLOWING NATURAL CULTIVATED VEGETATION COMPLEXES. THIS ARTICLE DESCRIBES HOW, ON BASIS OF PRELIMINARY WORK UNDERTAKEN AS PART OF THE CILSS MONITORING PROJECT, THE JOINT ANALYSIS OF THESE SATELLITE DATA ALLOWS AN IMPROVEMENT OF THE MONITORING OF RAINFED CROPS IN WEST AFRICA. THE ELEMENTS OF THE APPROACH WHICH STILL NEED FURTHER RESEARCH ARE IDENTIFIED. FINALLY THE PROBLEMS OF AVAILABILITY AND RELIABILITY OF SATELLITE MEASUREMENTS ARE MENTIONED.
