This study, based on work in six villages, seeks insights into the likely effect of the introduction of prospective land‐, water‐, and crop‐management technologies, being researched at the International Crops Research Institute for the Semi‐Arid Tropics, on the existing village labour‐use patterns in one major relevant region: peninsular India. Explicit attention is given to the similarities and differences between small and large farms and their relevance to the adoption of the prospective new technologies. Regional variation in labour utilisation reveals a tremendous employment‐creating potential in the existing tank and well irrigation systems in the Alfisols of peninsular India. The prospective technologies should increase employment, compared with existing technologies, by at least 100 per cent in the Alfisols and by over 300per cent in the deep Vertisols— but with some increase in the seasonal variability of labour demand. Given the existing availability of labour, there will be, with the improved watershed technologies, major farm labour bottlenecks. These should eventually generate increased wage rates and employment potentials. However, even temporary adverse effects on the timelessness of operations could be critical to the success of a double‐cropping and/or intercropping technology aiming at greatly increased yields. This would create demands for selective mechanisation, for example, of threshing. 相似文献

This study probes into the governing issues centering around the water use dispute and resolution between Richmond City and Henrico County in the Greater Richmond area, Virginia. For a variety of reasons, Richmond City strongly opposed the initiative by Henrico County to construct and operate its own water treatment plant in 1987. As a result of rigorous multi-party planning, mediation, and negotiation processes, Richmond City and Henrico County finally reached a compromise settlement in 1994. This study concludes that mediating and resolving public policy disputes between localities within the metropolitan area is a highly complicated and politically charged process, which can involve different levels of government, business community elites, and other stakeholders; driven by their common interests, the public-private intersectoral boundaries are increasingly blurred; and a planning process blends both political and technical factors together. In this case, the Henrico County's newly proposed water treatment plant project was environmentally cleared by the Water Review Panel's technical report. 相似文献

There are political and environmental challenges in the Nile Basin. In the past, Egypt's military dominance, civil wars in Sudan and Ethiopia, and negligible use of water by upstream states muted political tensions. But demands for a fairer share of the Nile River have resurfaced, and many countries have openly defied the imposed regime, meaning the 1929 agreement between Egypt and Britain and the 1959 bilateral agreements between Egypt and Sudan. The literature suggests this can lead to both conflict and co-operation. The dominant power-based and interest-based regime theories of international relations differ in their formulation of actors or actors' preferences over outcomes. This article argues that, while the former is the most powerful tool to explain what has happened in the past, the latter theory has a much more nuanced and explanatory power in terms of what will happen in the future in the Nile Basin. 相似文献

This article analyses the effect of governance in the delivery of public services, and the advantages of collaboration with the private sector in the provision of these public services. The article is not intended to be the conclusions drawn from an empirical study, but rather is based on the experience of a practitioner who has worked as a civil servant in the public sector and as a manager in the private sector. The advantages of private participation are listed, without prejudicing the role of regulator which must be exercised by the public sector. 相似文献

陕南是国家南水北调工程(中线)主要的水源地和陕西"引汉济渭"工程的水源地,其水资源状况对华北地区和关中地区的未来具有重大意义。从制度上保证陕南水资源的量与质,是必然的选择,水资源补偿机制的建立则是其重要内容。根据国家法律规定、国内外实践和经济学理论,并结合当地的实际情况,陕南水资源补偿机制应以政府主导模式为主,以一般性财政转移支付、水资源使用费返还等构建主要补偿基金;辅以市场调节的方式,引入国外资金和民间资金;给予永久性粮食补助等,以此三者的综合,形成陕南水资源的长效补偿机制。 相似文献

This is a systematic study that examines several acid prewashes and water rinses on paper bearing latent prints before its treatment with a silver physical developer. Specimens or items processed with this method are usually pretreated with an acid wash to neutralize calcium carbonate from the paper before the treatment with a physical developer. Two different acids at varying concentrations were tested on fingerprints. Many different types of paper were examined in order to determine which acid prewash was the most beneficial. Various wash times as well as the addition of a water rinse step before the development were also examined. A pH study was included that monitored the acidity of the solution during the wash step. Scanning electron microscopy was used to verify surface calcium levels for the paper samples throughout the experiment. Malic acid at a concentration of 2.5% proved to be an ideal acid for most papers, providing good fingerprint development with minimal background development. Water rinses were deemed unnecessary before physical development. 相似文献

This paper select the Jiangxi province located in the South of China and the Tarim river basin located in the North as two representative cases to empirically analyze the characteristics, the strengths and weaknesses of water rights development in the South and North, then point their significance for the whole country. Comparing and summarizing their differences and identities, the author point the future path of water rights development in China. 相似文献

This article uses two case studies to illustrate how Andean irrigation development and management emerges from a hybrid mix of local community rules and the changing political forms and ideological forces of hegemonic states. Some indigenous water-control institutions are with us today because they were consonant with the extractive purposes of local elites and Inca, Spanish and post‐independence Republican states. These states often appropriated and standardised local water-management rules, rights and rituals in order to gain control over the surplus produced by these irrigation systems. However, as we show in the case of two communities in Ecuador and Peru, many of these same institutions are reappropriated and redirected by local communities to counteract both classic 'exclusion-oriented' and modern 'inclusion-oriented' water and identity politics. In this way, they resist subordination, discrimination and the control of local water management by rural elites or state actors. 相似文献
