Simulation Planning for Sustainable Use of Land Resources: Case study in Diamou

Abstract

In this study, we presented the simulation planning scheme to project land and land resources use changes at a local scale for Diamou (MALI). Problem statement: All the land cover types were under the influence of human and livestock population. Diamou has undergone changes in land-cover over the last decades. The shifting cultivation system practiced was probably the main reason for this state of affairs. Moreover, the dryness and extensive character of pastoral activities had contributed to the general degradation of natural resources. The principal objective of our study was to contribute to the sustainable use of land resources from 1999-2010. Approach: Using formula the resources supply and demand had been estimated based on statistics data, derived from a comprehensive review of the literature. The resources balance (difference between supply and demand) had been estimated for two years 1999 and 2010.The resources demand were measured by an average consumption needs person^-1 day^-1 multiplied by the population. For the livestock population the biomass demand and supply had been measured based on TLU dietary requirements and the pastureland carrying capacity. The diagram of resources balances were drawn using word Microsoft word command and the simulation land use areas schema using ArcGIS. Results: From present approach, it was found, that, in year 1999 the fuel wood and cereal balances were negative. The drink water and biomass balances were positive. The dominant land use categories were the pastureland and the cropland, occupying about 52 and 45% of total area respectively of the total area 8876 ha. Except the biomass balance in year 2010, all the resources balance were negative. The drink water and fuel wood deficits were equal to 439 and 2801 m³ respectively. The dominant land use class, a cropland covered approximately 45% of total area. Conclusion: Studies had indicated the cereal, fuel wood and drink water resources deficit in years 1999 and 2010.
