This paper considers the principal elements that underpin policy frameworks for supporting food security in protracted crisis contexts. It argues that maintaining the food entitlements of crisis-affected populations must extend beyond interventions to ensure immediate human survival. A 'policy gap' exists in that capacities for formulating policy responses to tackle the different dimensions of food insecurity in complex, fluid crisis situations tend to be weak. As a result, standardised, short-term intervention designs are created that fall short of meeting the priority needs of affected populations in the short and long term and only partially exploit the range of policy options available. The paper discusses key attributes of agency frameworks that could support more effective policy processes to address longer term as well as immediate food security needs. Additionally, it points to some main challenges likely to be encountered in developing such frameworks and, with the participation of beneficiaries, translating them into effective action.  相似文献

概括了国际河流开发和管理特征、存在的主要问题和“流域整体开发和管理”的演进过程 ,分析了系统理论和可持续发展理论的具体体现 ,提出国际河流整体开发和管理主要体现在以下三个方面内容 :(1)强调区域之间的联系 ,要求从全流域的角度 ,而不是仅仅从国家的角度来进行开发和管理。在资源开发和管理中兼顾各流域国的目标 ,体现公平合理性 ,要求一国的开发利用对其它流域国不造成重大损害 ;要求各流域国加强合作。 (2 )强调流域内各要素的相关性 ,要求资源的开发和管理中考虑相关资源的利用问题 ,如与水资源相关的土地资源利用问题 ,以及国家之间的制度协调等社会人文因素。 (3)要求考虑河道生态系统的可持续性 ,维护流域的可持续发展。  相似文献

In the crustacean Eudiaptomus gracilisSars, relationships between mortality (D) and the ratio of main cations (R, the ratio of the sum of potassium and sodium equivalent concentrations to the sum of calcium and magnesium equivalent concentrations) were studied. The calculated regression equation D= 315 – 355/Rwas used for predicting the state of E. gracilispopulation in Lake Poppalijarvi (Karelia) polluted with mining waste. At R< 0.47, the population will survive; at R> 1.53, its extinction should be expected. The results of hydrobiological observations on Lake Poppalijarvi confirmed the prognosis based on the equation.  相似文献

Urban Waste Pollution in the Korle Lagoon, Accra, Ghana   总被引:1,自引:0,他引:1  
The Korle Lagoon in Accra, Ghana, has become one of the most polluted water bodies on earth. It is the principal outlet through which all major drainage channels in the city empty their wastes into the sea. Large amounts of untreated industrial waste emptied into surface drains has led to severe pollution in the lagoon and disrupted its natural ecology. The increased levels of industrial activity and consumption by the urban population lead to the generation of copious quantities of waste. Managing the volume of wastes poses a major challenge for the city authorities, particularly, ensuring that all the waste generated is collected for disposal. In Accra, the Waste Management Department is currently capable of collecting only 60 percent of the waste generated daily. The rest is dumped in open spaces, in surface drains, and into water bodies which end up in the Korle Lagoon. High eutrophication levels have developed in the shallow water body. The net effect is that, at the slightest downpour, the lagoon overflows its banks causing regular flooding in parts of the city.The Government of Ghana, having realized the adverse impacts of pollution in the lagoon on the physical and economic environment of Accra, with the support of donor agencies, is implementing measures to restore the lagoon to its natural ecology. Attempts are also being made to get the communities in the catchment area to become involved in managing their environment through environmental education and awareness programes.  相似文献

我国现代人地关系与资源环境基础   总被引:12,自引:0,他引:12  
在经过了40 多年大规模建设,中国工业化发展面临着来自有限资源环境越来越大的压力。从协调人地关系紧张矛盾的角度出发,中国未来经济的发展不仅需要增加资金和科技投入,而且也需要提高资源投入的质量。欲达此目的,扩大资源的国际贸易,特别是石油、天然气的进口就变得十分重要  相似文献

ABSTRACT: Four years of monthly freshwater discharge and constituent concentration data from three tributaries were related to a concurrent series of data for three segments of the St. Lucie Estuary in South Florida using multiple regression and time-series analysis techniques. Water quality parameters examined were dissolved inorganic and total nitrogen and phosphorus, chlorophyll a, total suspended solids, turbidity, and color. On monthly time scales, a multiple regression, which included freshwater discharge, freshwater constituent concentration, and dilution with ocean water (salinity) as independent variables, explained 50 percent or less of the variability in estuarine constituents. No single independent variable explained more variation than another. By contrast, on seasonal (wet, dry) time scales, freshwater discharge explained the bulk of variation in estuarine water quality (up to 93 percent). On monthly time scales, variability in concentrations of nutrients and other constituents may be largely controlled by processes internal to the system. At seasonal time scales, freshwater discharge appears to drive variability in most estuarine water quality parameters examined. Results indicate that management of tributary input on a seasonal basis, with the expectation of achieving seasonal concentration goals in the estuary, would have a higher probability of success than managing on a monthly basis.  相似文献

本文对目前国内所使用和已提出讨论的校准曲线回归计算方法与国际标准校准曲线回归计算方法进行了比较和讨论,表明无论采用何种回归方法进行计算,对测定结果的精密度和准确度均无显著影响。但为了使校准曲线的回归计算方法国际化、标准化,建议采用国际标准回归法。  相似文献
