3. Land restoration and revegetation.

In: FAO Conservation Guide No. 21, "Role of Forestry in Combating

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.

- to enhance food production and also to generate income and to improve the quality of life through resource conservation and development.

The specific goals are:


- Protection of the soil from wind and water erosion and maintenance of its fertility.

- Protection of catchment areas and perennial and seasonal water courses to assure regulated flow of water both in quantity and quality. Also efficient and wise use of the scarce resource of water.

- Enhancement of the productive role of the vegetation to realize maximum production of fodder, wood, fibers, medicinal products, tannins, perfumes, gums and other products.

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:
- Agro-silvicultural methods
- Shelterbelts
- Plantations on seriously degraded irrigated or rainfed crop land
- On rangeland
- On forests and woodlands
- On bare land: sand and sand-dune fixation

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.

- Active peoples' participation, through various means, as no government can cope with these problems.

- Building and strengthening the staff base at all levels to execute these programmes, and filling the present gaps in knowledge.

- Integration of all available knowledge into working practical models that can solve the problems.

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.
