【 摘 要 】

A Benefit-Cost Analysis (BCA) wasundertaken to assess the returns to land managementpractices of major land use types, namely forests,rangelands, and selected crops (rice, maize, cotton, andmillet).Also the public expenditure on SLM was reviewedand an assessment carried out how the expenditure is alignedto land policies and how it is targeted to land degradationhotspots. The results show that, without some form ofincentives for communities around forests in Sikasso,farmers will continue to clear the forest and plant maize.This underscores the importance of providing payments forecosystem services for communities in the proximity offorests in Sikasso. Rotational grazing increases the averageforage biomass by 7 percent to 20 percent.However, evenfor rotation grazing, forage biomass shows a decliningtrend, underscoring the severe overgrazing problem.Thissuggests rotational grazing alone may not be able to fullyaddress the area's declining pasture quality.BCA ofcrops shows that for maize, rice, and cotton, landmanagement practices that combine fertilizer, manure, andcrop residues are more profitable and competitive than thosewhich use any of the three practices alone.
