Desertification"; FAO, Rome, 1989, pp. 253-265
This paper deals with the objectives of land restoration and revegetation, the strategies and practices carried out to realize the objectives within the context of the constraints, and arrives at recommendations of lines of action to deal with the problem.
The broad objectives of land restoration and revegetation are:
- to restore the land and vegetation for increased food production.
The specific goals are:
- Protection of the soil from wind and water erosion and maintenance of its fertility.
Land restoration and revegetation is carried out through execution of corrective measures on land where the degradation has occured. The current measures usually executed are summarized in this paper such as:
- On cultivated land:
The case studies discussed illustrate what happens when vegetation is destroyed by imbalanced use of land.
The following conclusions and recommendations are drawn:
Land and vegetation degradation is essentially a land use problem and the key to success for restoration and revegetation centres on:
- Integration of land use within ecological context.
No effort on land restoration and revegetation can achieve its objectives without the active participation of the people. This cannot be done without motivation. That coercion through laws alone has largely failed needs no illustration. There is a need for studies to evolve methods of motivation, coercion and others that can lead to sound practices of efficient utilization and conservation.
