Advantages of adopting 'economic' rather than 'financial' analyses in land evaluation include: ii. is characterised by specific combination of surface features and soil characteristics. 129. pp. If the results of this check prove unfavourable, it is necessary to review and test all assumptions in the analysis. Finally, comparing the required gross irrigation water requirement and available monthly flow of the River, the River has the capacity for the fulfilling irrigation water demand to irrigate command area of the watershed during dry season. In the context of economic analysis any expenditure must be justified, on the grounds that benefits exceed costs, and enable the resultant productivity of the land (after the expenditure) to remain above the cut-off value. Budgets representing the future situation 'with' the project will be required for whatever number of LUTs it is desired to examine for a land unit. As explained in Chapter 1, land suitability evaluation is essentially an economic concept. The next step should involve an on-site investigation. Pap. The land evaluation team must decide which of these measures of suitability is most appropriate for a given evaluation. 7.3.1 Copyright 10.
