This working paper addresses the issues: 1) whether there is a simultaneous equations problem when estimating demand for water with multipart rate schedules and, if there is one, what techniques should be used to correct for it; and 2) whether average or marginal price is the relevant measure in...

The staff working paper ‘Stranded Irrigation Assets’ (Roper, H., Sayers, C. and Smith, A) was released on 28 June 2006. Prior to the National Water Initiative (NWI), irrigation authorities imposed restrictions on outward trade of water entitlements partly to protect remaining irrigators...

Climate describes the temperature, precipitation and other weather condition. Climate modification by the progressive warming of the atmosphere resulting from the concerted action of several factors, both natural and anthropic favours the diminution of precipitations at soil level, corroborated...

Beijing-Tianjin-Hebei region is one of the most developed areas in China with a most rapid rate of economic growth. It is also a well-known region suffering great water scarcity. The water resources per capita is 118.60m³, 99.46 m³, 240.57 m³ respectively in Beijing, Tianjin and Hebei in...

This study represents the first attempt at an integrated approach to assessing the potential impacts of climate change on the national economy of South Africa via a number of (but not necessarily all) impact channels. The study focuses on outcomes by about 2050. The results show the multiple...

The aim of this study is to analyze the characteristics and dynamic performance of the Water Resources Sector Fund of the Ministry of Science and Technology (CT-Hidro/MCT) as a result of the partnership between the Ipea and the Brazil's MCT. Quantitative and qualitative aspects, as well as...

Many conflicts currently take place around the world due to disputes over water use. In many major river basins of the world, water is increasingly scarce. In Brazil, some regions face problems of water deficiency, such as the Northeastern semi-arid region and some metropolitan areas. The aim of...

The paper examines the influence of factor price risk on factor-use efficiency through the adoption of conservation technology. The effect of a mean-preserving increase in factor price risk on optimal input-use efficiency is shown to be conditional on the own-price elasticity of factor use...

An assessment of the impacts of projected climate change on water availability and crop production in the Volta Basin and the southwestern and coastal basin systems of Ghana has been undertaken as a component of the impacts and adaptation study for Ghana by UNU-WIDER and the University of Ghana....

While the extent of human induced global warming is inconclusive, the vulnerability of natural systems to rapid changes in climate patterns is regarded as one of the most challenging issues in recent years. Water resources are a main component of natural systems that might be affected by climate...
