Remote sensing and agricultural production monitoring in Sahelian countries
Agricultural production monitoring has for many years been seen as an important field of investigation for the remote sensing research community. Considerable efforts have been made to define the estimation of crop production, but these results are not used to any great extent in theeh operational monitoring and early warning systems set up by national and international agencies. This is partly due to the lack of relevance of the scientific results to the needs of the end-user, and partly due to the cost of proposed techniques with regard to available budgets. The current state of the art shows that, while remote sensing techniques can be used in an operational way to improve agricultural statistical surveys, direct crop area estimates hardly seem feasible in Sahelian countries. Work still has to be done in order to find out if early estimates of global harvestable areas can be obtained with satellite imagery in this specific environmental context.
