Book Synopsis Measuring Transboundary Water Cooperation by : Saruchera, D.
Download or read book Measuring Transboundary Water Cooperation written by Saruchera, D. and published by International Water Management Institute (IWMI). This book was released on 2015-12-31 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water cooperation has received prominent focus in the post-2015 United Nations Sustainable Development Goals (SDGs). While proposals for measuring water cooperation appear to be converging toward a small set of indicators, the degree to which these proposed indicators draw on past work is unclear. This paper mines relevant past work to generate guidance for monitoring the proposed SDG target related to transboundary water cooperation. Potential measures of water cooperation were identified, filtered and applied in three countries (Botswana, South Africa and Zimbabwe). Six indicators were ultimately determined as being suitable for measuring water cooperation. As the SDG process turns its focus to the selection of indicators, the indicators proposed in this paper may merit consideration

This book was released on 2017-06-05 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project. Based on a combination of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, previous irrigated area mapping exercises carried out by DAFF and three-field ground truthing (GT) surveys, a total of 1.6 million hectares (Mha) of cropland were identified, with 262,000 ha actually irrigated in the 2015 winter season. The study also found that only 29% of all land equipped with center pivots was actually irrigated.

Book Synopsis Methods to investigate the hydrology of the Himalayan springs by : Chinnasamy, Pennan
Download or read book Methods to investigate the hydrology of the Himalayan springs written by Chinnasamy, Pennan and published by International Water Management Institute (IWMI).. This book was released on 2016-06-10 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Springs are the major source of freshwater in many small mountainous watersheds within the Himalayan region. In recent years, their flow rates have diminished, but the reasons for this are not self-evident, and hence this paper reviews the methods to investigate Himalayan springs. The review reveals that chemical and isotope analyses – mostly water dating and stable isotope (e.g., d18O) analyses – could be an appropriate entry point to commence field investigations, because of their potential to map complex spring pathways, including linkages between aquifers. This should be combined with the building of hydrogeological maps with the available data. Output from desktop analyses, field investigations and hydrogeological maps could then contribute to the establishment of a conceptual model, which could form the basis for a numerical model.

Book Synopsis Smallholder irrigation schemes in the Limpopo Province, South Africa by : van Koppen, Barbara
Download or read book Smallholder irrigation schemes in the Limpopo Province, South Africa written by van Koppen, Barbara and published by International Water Management Institute (IWMI). This book was released on 2017-06-08 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project. About one-third of those schemes was fully utilized; one-third partially utilized; and one-third not utilized in the winter of 2015; however, no single socioeconomic, physical, agronomic and marketing variable could explain these differences in utilization. Sale, mostly for informal markets, appeared the most important goal. Dilapidated infrastructure was the most important constraint cited by the farmers. The study recommends ways to overcome the build-neglect-rebuild syndrome, and to learn lessons from informal irrigation, which covers an area three to four times as large as public irrigation schemes in the province.

Book Synopsis Modeling Water Resources Management at the Basin Level by : Daene C. McKinney
Download or read book Modeling Water Resources Management at the Basin Level written by Daene C. McKinney and published by IWMI. This book was released on 1999 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

Book Synopsis An Assessment of Integrated Watershed Management in Ethiopia by : Gebregziabher, Gebrehaweria
Download or read book An Assessment of Integrated Watershed Management in Ethiopia written by Gebregziabher, Gebrehaweria and published by International Water Management Institute (IWMI).. This book was released on 2016-12-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable participatory watershed management is an approach promoted by the Ethiopian government to restore natural resources and agricultural productivity across the country. This comparative study between six watershed programs shows that this approach increases farmers’ food security and incomes (around 50% on average), as well as their resilience to drought and other climate shocks. However, the study also confirms that the nature and scale of impact can vary significantly between watershed programs. The success of watershed management depends on multiple factors from the hydrological profile of the watershed to the local social and economic environment. Tailoring watershed interventions to the local context, associating conservation and livelihoods activities, and providing further financial and technical support to watershed committees are among the recommendations of this paper.
Book Synopsis A Hydroeconomic Model for Water Resources Assessments with Application to the Apalachicola Chattahoochee Flint River Basin by : Frederick Masolo Kimaite
Download or read book A Hydroeconomic Model for Water Resources Assessments with Application to the Apalachicola Chattahoochee Flint River Basin written by Frederick Masolo Kimaite and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several river basins in the world are faced with growing water scarcity and water use conflicts attributed to increasing water demand and competition among users, climate change and variability, and environmental degradation. Addressing these challenges necessitates shifting from the traditional uncoordinated sectoral approach to more integrated and fully participatory approaches supported by credible information generated by reliable and robust technical tools. Combining engineering, economics and hydroclimatological science, hydro-economic tools are well suited to provide reliable and impartial technical information that can support multi stakeholder negotiation and decision making processes in a river basin. This research develops and applies a detailed hydro-economic model to support multi-objective water resources assessments. The model supports integrated assessments of physical and economic impacts of changes in water demand, climate conditions, water resources management objectives and policies, and other system constraints on a basin's water resources. The main contribution of this research is the systematic coupling of detailed water resources and economic assessment models that are capable of (a) representing complex physical system characteristics and constraints; (b) simulating system operation at diverse temporal and spatial scales; and (c) representing water-based economic production processes at a basin scale. The research integrates a wide range of potential climate change impacts into the hydro-economic modeling framework through consideration of multiple future climate change scenarios from 13 Global Circulation Models under the medium and high emission projection scenarios. Economic uncertainty is characterized through conjunctive use of Monte Carlo simulation and Geometric Brownian Motion techniques to generate multiple forecast traces of important economic parameters. The model is applied to the Apalachicola-Chattahoochee-Flint River basin in the southeast USA as a case study.
Book Synopsis Water accounting & auditing guidelines by : Batchelor, C
Download or read book Water accounting & auditing guidelines written by Batchelor, C and published by Food & Agriculture Org.. This book was released on 2016-01-01 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many regions of the world, sustainable and reliable delivery of water services has become increasingly complex and problematic. Complexities that are very likely to increase, considering the unprecedented confluence of pressures linked to demographic, economic, dietary trends, and climate change. Particularly if overall demand for freshwater exceeds supply, the delivery of water services is often less about engineering, although engineering is still required, and more about politics, governa nce, managing and protecting sources, resolving conflicts about water, ensuring rights to water are respected, and so on. It is also about understanding and monitoring the hydrological cycle at the appropriate scale of analysis. This is where water accounting and auditing can play a crucial role. The rationale behind this water accounting and auditing sourcebook is that scope exists worldwide to improve water-related sectoral and inter-sectoral decision-making at local, regional and national le vels. Water accounting and auditing are recommended by FAO and others as being fundamental to initiatives that aim to cope with water scarcity. This sourcebook aims to provide practical advice on the application and use of water accounting and auditing, helping users planning and implementing processes that best fit their needs.

Download or read book A Hydro-Economic Approach to Representing Water Resources Impacts in Integrated Assessment Models written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Grant Number DE-FG02-98ER62665 Office of Energy Research of the U.S. Department of Energy Abstract Many Integrated Assessment Models (IAM) divide the world into a small number of highly aggregated regions. Non-OECD countries are aggregated geographically into continental and multiple-continental regions or economically by development level. Current research suggests that these large scale aggregations cannot accurately represent potential water resources-related climate change impacts. In addition, IAMs do not explicitly model the flow regulation impacts of reservoir and ground water systems, the economics of water supply, or the demand for water in economic activities. Using the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) model of the International Food Policy Research Institute (IFPRI) as a case study, this research implemented a set of methodologies to provide accurate representation of water resource climate change impacts in Integrated Assessment Models. There were also detailed examinations of key issues related to aggregated modeling including: modeling water consumption versus water withdrawals; ground and surface water interactions; development of reservoir cost curves; modeling of surface areas of aggregated reservoirs for estimating evaporation losses; and evaluating the importance of spatial scale in river basin modeling. The major findings include: - Continental or national or even large scale river basin aggregation of water supplies and demands do not accurately capture the impacts of climate change in the water and agricultural sector in IAMs. - Fortunately, there now exist gridden approaches (0.5 X 0.5 degrees) to model streamflows in a global analysis. The gridded approach to hydrologic modeling allows flexibility in aligning basin boundaries with national boundaries. This combined with GIS tools, high speed computers, and the growing availability of socio-economic gridded data bases allows assignment of demands to river basins to create hydro-economic zones that respect as much as possible both political and hydrologic integrity in different models. - To minimize pre-processing of data and add increased flexibility to modeling water resources and uses, it is recommended that water withdrawal demands be modeled, not consumptive requirements even though this makes the IAM more complex. - IAMs must consider changes in water availability for irrigation under climate change; ignoring them is more inaccurate than ignoring yield changes in crops under climate change. - Determining water availability and cost in river basins must include modeling streamflows, reservoirs and their operations, and ground water and its interaction with surface water. - Scale issues are important. The results from condensing demands and supplies in a large complex river basin to one node can be misleading for all uses under low flow conditions and instream flow uses under all conditions. Monthly is generally the most accurate scale for modeling river flows and demands. Challenges remain in integrating hydrologic units with political boundaries but the gridded approach to hydrologic modeling allows flexibility in aligning basin boundaries with political boundaries. - Using minimal reservoir cost data, it is possible to use basin topography to estimate reservoir storage costs. - Reservoir evaporation must be considered when assessing the usable water in a watershed. Several methods are available to estimate the relationship between aggregated storage surface area and storage volume. - For existing or future IAMs that can not use the appropriate aggregation for water, a water preprocessor may be required due the finer scale of hydrologic impacts.
