As the problems of impact assessement are rather intractable, a fairly simple dual approach is proposed. First the major components of environmental impact of current agricultural production systems in Africa (i.e. impact of cropping, livestock keeping, fuelwood and timber extraction and burning)...

We investigated variation in age-adjusted fuelwood properties of Balanites aegyptiaca, Combretum glutinosum, Guiera senegalensis, Piliostigma reticulatum and Ziziphus mauritiana along latitudinal transects in five regions extending from eastern to western Mali. The objectives were to determine if...

The interactions between natural forest dynamics have to be taken into account when managing the use of forest resources. Simulation models were developed to improve the understanding of this complex system of interactions. Models of multi agent systems are effective tools for studying the dynami...
