| Chapter 3 – Expansion of concepts and definitions
Functions of the land Limiting factors on the land Concepts and definitions The concepts and definitions of the 1976 Framework that are still valid will need to be repeated, integrated with the new or expanded concepts and definitions. Chapter 4 – Land suitability classifications Structure of the suitability classification The range of classifications The results of land suitability evaluation The original Framework defines land suitability classification as ‘an appraisal and grouping, or the process of appraisal and grouping, of specific types of land in terms of their absolute or relative suitability for a specified kind of use.’ In essence, this definition remains valid. Because land performs a multitude of functions and services, often but not necessarily in parallel with a specific use of the land, the last part of this definition should be expanded. The reformulation could be along the lines of ‘… a specific kind of use, function or service, or a specific combination of these’. Chapter 5 – Land evaluation procedures Initial consultations Diagnosis of land use problems Description of the land utilization types Kinds of land use and their requirements and limitations Land evaluation – towards a revised framework 40 Description of functions and services of land Description of land mapping units and land qualities Economic and social analysis Comparison of land use with land Land suitability classification Synopsis of procedures Presentation of results Land evaluations following the revised Framework should make use of appropriate tools, most of them recently developed that have been validated and successfully applied. The examples in Annex 4 do this in a patchy way. A review of a wider range of case studies should show which tools have been used frequently and successfully in land evaluation. The scheme in Figure 1 can form a starting point. The revised Framework should focus on principles and procedures, rather than recommending specific tools and methods, but an overview of proven, recent and more traditional tools and methods would constitute a useful annex. tải về 0.57 Mb.
