6. Guidelines: land evaluation for rainfed agriculture.

FAO Soils Bulletin No. 52, FAO, Rome; ISBN 92-5-101455-8, 1984, 191 p. + appendices

The principal objective of land evaluation is to select the optimum land use for each defined land unit, taking into account both physical and socio-economic considerations and the conservation of environmental resources for future use.

The need for optimum use of land has never been greater than at present, when rapid population growth and urban expansion are making land available for agriculture a relatively scarce commodity. The increasing demand for intensification of existing cultivation and opening up of new areas of land can only be satisfied without damage to the environment if land is classified according to its suitability for different kinds of use.

These "Guidelines" are intended to assist field staff in carrying out land evaluation for rainfed agriculture according to the principles of the FAO Framework for land evaluation. The present publication is an expansion of the basic concepts of the framework giving procedures and methods necessary in evaluation for rainfed agriculture. It provides practical guidelines on the planning and execution of the various steps in land evaluation, from interpretation of basic data to the final recommendations which form a basis for land use planning and project implementation.

The "Guidelines" refer only to crop production. Both annual crops (arable farming) and perennial crops (tree and shrub crops) are included.

The procedures are applicable at all levels of scale, ranging from continental or national, through regional and district scales, down to detailed or intensive surveys for local projects, village-level schemes and farm planning.

These "Guidelines" occupy a position intermediate between the "Framework for Land Evaluation" and detailed local manuals on evaluation. The "Framework" gives the principles and basic concepts on which land suitability evaluation is based, and indicates overall strategies for their application. The "Guidelines" provide a detailed methodology for carrying out the strategies.

In attempting to be fairly comprehensive, the Guidelines present the maximum range of procedures or aspects to be covered. Some procedures are covered only briefly. Similarly, the checklists are intentionally long to ensure that no relevant aspect is overlooked.
