Population and land degradation. 

 - s.l :  s.n,  1994. 
<br/><br/> The paper examines mechanisms through which mounting demographic pressure leads to soil erosion and the depletion of soil fertility. The authors argue that there exists no direct links between human populations and their environments and that the intervening process create the context within which land degradation occurs.
