| xi. Land suitability classification
The results of the matching process are combined with those of the cross-sectoral analysis, environmental impact and risk assessment, production modelling, agro- environmental indicators and economic and social analysis to produce a classification showing the suitability of each land mapping unit for each relevant kind of land use. This land suitability classification needs to be checked in the field. xii. Presentation of results Resulting from the added activities, further types of information appear in the results of the land evaluation. This information, and the proposed course of action which is suggested, should be presented to all stakeholders at any early stage, to allow wide discussion. A practical point is that project and staff time should be allowed for making modifications consequent upon the responses received. 39 Chapter 5 Outline of a revised framework for land evaluation The principles, concepts and procedures set out in the 1976 Framework remain valid almost without exception. However, in order to strengthen the Framework, in the light of present world circumstances and views, there is a need for expansion, as indicated by discussion in the present document. The new material could be incorporated with the old on the following lines. Each chapter would start with an untitled introduction. Preface Chapter 1 – The need for revision Origin and application of the Framework for land evaluation An expanded definition of land and land resources Trends calling for revision Chapter 2 – Historical development of land evaluation Land evaluation and classification before the Framework Origin and nature of the Framework Land evaluation systems originating since the Framework The development of a revised Framework This chapter would largely correspond to the present Chapter 2. tải về 0.57 Mb.
