Some systems of medium size may, with their drainage water, be supporting small irrigation systems unknown to officials of water and land development agencies. With a decision to modify the water flow pattern of a medium-size system, the administrators who plan the modifications should learn whether such dependent systems occur. This paper suggests that dependent systems are more likely to have been created on gently sloping land cut by gullies and small, locally deep valleys than on land without such valleys. It also suggests that aerial photographs, satellite images, maps, and government records may not provide information on the locations of the systems, and that such information be sought instead from farmers.</p></div>","PeriodicalId":100060,"journal":{"name":"Agricultural Administration and Extension","volume":"30 4","pages":"Pages 281-291"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0269-7475(88)90100-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80107220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is recognised that such projects will only succeed in a sound institutional and policy environment. Such an environment is examined, and a project is designed which overcomes perceived constraints. The achievement of donor loan effectiveness, and the procurement of required goods and services are reviewed. The assembly of data for the estimation of planned project benefits is the next consideration as the sizes and annual phasing of several project cost items will depend on when and at what rate project benefits are to be achieved. A checklist of project cost items is then presented. Project costs are assembled on a component basis. Within each component, costs are built up by category commencing with technical staffing; which to some extent determines the requirements for support staff, housing, office space, vehicles, and capital equipment. The provision of buildings, vehicles and equipment, and staff then determine levels of maintenance and repair, operating, and administrative recurrent costs. Pragmatic methods are advanced which could be used as a starting point for the estimation of such recurrent costs. Project costs may have to be rearranged to meet the particular needs of financing agencies. It is noted that the compilation of project costs with the aid of a personal computer spreadsheet program is useful in terms of the construction of cost tables, their rearrangement if required, and subsequent sensitivity analysis. The purposes and presentation of the project appraisal report are then considered.</p></div>","PeriodicalId":100060,"journal":{"name":"Agricultural Administration and Extension","volume":"30 2","pages":"Pages 143-157"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0269-7475(88)90122-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81156888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
