| Scale and level of decision-making
Another additional principle is that the scale and level of decision-making should be defined prior to land evaluation. Identifying the scale and decision-making level are important not only for selecting the data survey techniques and analysis tools, but also for reporting which stakeholders and sectors have been explicitly taken into account and are primarily addressed in the analysis. The principles and general procedure of land evaluation are scale-independent, but the specific tools and methods should be tuned to the goals, the decision-making level en the envisaged scale. A land evaluation designed to respond to the needs of regional planners might not provide results directly relevant for individual farmers, because their questions and interests are different from those of the planners and because the required scale would be much more detailed. The timeframe of a land evaluation exercise will also depend on the scale and detail required. OUTLINE OF PROCEDURES A schematic representation of proposed land evaluation procedures is presented in Figure 1. This is based on the figure presented in the 1976 Framework, but several activities and paths have been added. In this scheme, the socio-economic components of diagnosis and design form an important contribution. Diagnosis and design is a methodology developed at ICRAF (1983a and b) for identifying the best system of improved land use for given sites, specifically related to agroforestry but also applicable to other land use systems (Young 1985; 1998 p.75). It has essentially the same aim as land evaluation but is stronger in the treatment of social aspects. Since most development projects entail modifications of existing systems, land evaluation can benefit through inclusion of procedures from diagnosis and design to diagnose the problems of the existing systems and design responses or solutions. Also, social analysis could draw upon some of the detailed methods in diagnosis and design. Note that the element of iteration, or a cyclic element, remains part of the procedure (indicated in Figure 1 by the arrows labelled “iteration”). Although the various activities are of necessity described successively, there is a considerable amount of revision to early stages consequent upon findings at later periods. Interim findings might, for example, lead to reconsideration of the kinds of land use to which evaluation Chapter 4 – Revised principles and procedures 33 is to refer, or to changes in boundaries of the area evaluated. This cyclic element should be kept in mind throughout the following description of procedures. With time, land evaluation has become increasingly integrated with other disciplines. Its basis still lies in the evaluation of the biophysical resources, but economic evaluation gained in importance and social and environmental components were included. There is an urgent need for an integrated approach between the different disciplines. This means that a multidisciplinary team of researchers is involved (or at least informed) in all stages of the land evaluation. A multi-stage approach is presented but at each stage, the knowledge and experience of the stakeholders and the different researchers is included in the considerations and if possible, integrated. tải về 0.57 Mb.
