{"title":"An alternative method of area measurement for large agricultural surveys","authors":"J.E. Moes,&nbsp;G. Sharrock","doi":"10.1016/0269-7475(88)90030-X","DOIUrl":"10.1016/0269-7475(88)90030-X","url":null,"abstract":"<div><p>The unsuitability of current ‘objective’ methods used in agricultural surveys of smallholder farming in Africa has often been stressed but scientifically tested alternative methods that may be used to replace them are yet to be developed. The present paper reports on the ‘Longest Diagonal Method’ of area estimation, with which encouraging results have been obtained in Malawi.</p><p>The field work consists of measuring the longest distance within the area (farm plots) from one end to another: in the testing stage, area estimates based on this variable, designated LD, were compared with the ‘known’ area as measured with tape and compass. At an early stage of our experimentation, an approach involving the computation of the mean of a factor F relating LD to the area A was rejected, and this was replaced by regression analysis in which a second diagonal, designated as the perpendicular or P, is also playing a role in combination with LD. This second diagonal P runs at a 90° angle from the midpoint of LD to the edges of the plot, and since the introduction of P the field work consisted of measuring both LD and P. After the introduction of shape classification based on the ratio R = P/LD as an indicator of a field's degree of compactness, valid aggregate area estimates were obtained and as regards farm size classification the results were also quite acceptable.</p><p>Hitherto, efforts to find alternative, more cost-effective methods that would enable agricultural surveys to provide reliable information on crop production at project level of disaggregation have focused almost exclusively on the possibility of using farmers' own estimates. However, this method taken in isolation has its limitations and to be fully effective a breakthrough in this direction, one way or another, needs to be complemented by a less cumbersome approach towards area estimation. While improved area estimation has merits in its own right as well, the most significant effect of the present contribution will be found in this combination.</p></div>","PeriodicalId":100060,"journal":{"name":"Agricultural Administration and Extension","volume":"28 1","pages":"Pages 59-73"},"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)90030-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76997469","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}

First, organizations' <em>capacity</em> is very difficult to assess, as it represents potential rather than just performance.

Second, most approaches to evaluation are themselves ‘top-down’ and thus inconsistent with the capacity they are supposed to assess. Ideally, one would have a system of evaluation that itself supports the value and process of ‘participation’ in development activities.

Several factors, however, negate the achievement of this goal. This paper focuses on the eight countries of the West African Sahel and discusses the implication of the lack of a critical mass of indigenous scientists in national programmes for conducting adaptive research on existing technologies or generating new ones for the particular situations of the region. The problems associated with these programmes are presented in the light of the number and calibre of personnel in agricultural research, the place of agriculture in national development, and the impact of foreign technical assistance. Measures for improving the domestic capacity of national programmes especially as they relate to training, are discussed. Regionalisation and networking programmes are also suggested as possible alternatives.</p></div>","PeriodicalId":100060,"journal":{"name":"Agricultural Administration and Extension","volume":"28 3","pages":"Pages 227-238"},"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)90038-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91696552","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}

The findings show the prime importance they attach to obstacles to their adoption of plant protection practices as deterrents to their acceptance of a modern rice cultivation system. In particular, because of their poverty they are unable to obtain and service many of the necessary practices, while those which they can acquire are often not available to them at appropriate times. They blame the commercial channels which supply inputs for this to a large extent. The farmers consider that cheaper equipment, greater access to irrigated land, and the timely availability of inputs could overcome many of the obstacles. Extension workers need to appreciate farmers' own perceptions of their problems and means of overcoming them if they are to offer useful advice.</p></div>","PeriodicalId":100060,"journal":{"name":"Agricultural Administration and Extension","volume":"29 4","pages":"Pages 293-300"},"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)90110-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87160419","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}
