Opening Paragraph

Opening ParagraphAs one goes through the numerous publications concerning East Africa, it becomes apparent that certain subjects have rarely been approached, having been neglected or even totally ignored. Such is the case concerning the problems linked with the Hadrami diaspora, the extended study of which—apart from a few notable exceptions—has not yet aroused the interest of historians or the curiosity of anthropologists.

Cross Compliance

Several studies have described the effectiveness of vegetated buffer strips, interposed between the cultivated areas and water bodies, in removal of suspended solids and other pollutants such as Glyphosate conveyed through surface runoff. This monitoring study has quantified the effects of a 5-metre wide herbaceous buffer zone, adjacent to a vineyard, built according to the Standard 5.2 of Cross-compliance (M.D. 27417). The amount of runoff generated was 3.9% of the total annual rainfall, with negligible differences in terms of volume after flowing through the buffer zone. The effectiveness of the buffer zone in suspended solids removal was, in terms of mass balance, of 45.5%. The glyphosate outputs from the vineyard, unlike in other experiences, were negligible and therefore it was not possible to evaluate the efficiency of the buffer zone in removing it. This is due to the low rainfall occurred in the period following distribution that has favoured <em>in situ</em> degradation of Glyphosate.
