This book was released on 2004 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Olifants River is one of the major tributaries of the Limpopo River. Approximately 3,400,000 people live in its catchment and a considerable proportion of South Africa’s mining, power production and agricultural activities are concentrated there. The catchment also encompasses important tourist destinations (e.g., the Kruger National Park). Consequently, in terms of the national economy it is one of the country’s most significant waterways. The catchment is one of the first in South Africa for which a Catchment Mangement Agency (CMA) is planned.
Download or read book Policies Legislation and Organizations Related to Water in South Africa with Special Reference to the Olifants River Basin written by H. Thompson and published by IWMI. This book was released on 2001 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study is reported in two Working Papers. Working Paper 17 reports the findings of the HIM exercise. This paper contains the policies, legislation and organizations relevant for understanding of the HIM for the Olifants river basin. It also includes the historical development of the institutional framework in the basin, as this history has left a profound imprint on the South African society at large and is still dictating, in many cases, the interactions between the different organizations. This background on previous and current institutions and policies at the different government levels is used to shed light on the current relationships between different organizations in the basin. Although focusing on the Olifants, the description provided is applicable to the rest of South Africa in broad terms.

This book was released on 2007 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were estimated for each sector and the economic cost of failing to provide water was predicted. For the future scenarios, the impact of infrastructure development and water conservation measures were assessed. The study illustrates how a relatively simple model can provide useful insight for resource planning and management.

Download or read book Irrigation and River Basin Management written by Mark Svendsen and published by CABI. This book was released on 2005 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing water scarcity, pressure to re-allocate water from agriculture to other uses mounts, along with a need to put in place institutional arrangements to promote 'higher value' uses of water. Many developing countries are now experimenting with establishing new institutional arrangements for managing water at the river basin level.This book, based on research by IWMI and others, reviews basin management in six developed and developing countries. It describes and applies a functional theory of river basin management, based on the idea that there is a minimum set of functions required to manage basins effectively and a set of basic conditions that enable effective management institutions to emerge. The book examines the experiences of both developed and developing countries in order to see what lessons can be learned and to identify what constitutes the core of a 'theory of river basin management'. It concludes that although it is difficult for developing countries to adopt approaches and institutional designs directly from developed countries, basic principles and lessons are transferable.
Download or read book Conceptual Overview of the Olifants River Basin s Groundwater South Africa written by John J. Aston and published by . This book was released on 2000 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper, commissioned by the International Water Management Institute (IWMI), presents an overview of the state of knowledge of groundwater issues in the Olifants River Basin in South Africa. It traces work, completed or ongoing, that has a direct or circumstantial relevance to the Olifants River Basin and presents a summary of the known state of existence of groundwater in the basin. The paper examines both the physical presence of the underground water and, though to a lesser extent, the social exploitation of this resource. The examination of the availability of groundwater will include a general description of the aquifer types, the recharge of water to these host aquifers and the flow of groundwater through and availability for extraction from the aquifers. The study goes on to look at the quality of this water, its present use, and the extent to which there are institutional bodies managing this water. By the end of this paper the reader should have a broad overview of the extent of the importance of this valuable natural resource to the development of the Olifants river basin together with an insight into the future potential to more fully yet sustainably utilise this resource. Overall the structure and content of the paper has been kept to a level that gives a good introduction to some of the themes relevant to the basin's groundwater reserve and acts as a platform from which to successfully manage future work.
Download or read book Politics and Development in a Transboundary Watershed written by Joakim Öjendal and published by Springer Science & Business Media. This book was released on 2011-11-25 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water - and its governance - is becoming a global concern partly because it is turning into a goods in short supply, with devastating effects on literally billions of people, but also because it is the "carrier" of global warming; whether through irregular weather patterns or through flooding, water is how global warming will be 'felt'. The lion's share of the globally available fresh water resources is to be found in transboundary systems. In spite of its significance, the generated knowledge on how to deal with transboundary waters is weak and leaves policy makers with seemingly unavoidable, trade-off dilemmas and prioritizations, often with detrimental effects. In order to disentangle this predicament this volume works with one case: the Lower Mekong Basin and covers state-of-the-art academic and practitioners' knowledge and hence appeals to a wide audience. The topic this volume addresses is situated in the nexus of an IR- (International Relations) approach focussing on transboundary politics and its inclination to remain within the sphere of state sovereignty and national interest on the one hand, and Development studies, with its imperatives on participation, planning, and intervention, on the other. The dilemma, we argue, of better understanding transboundary water management lies in how to understand how these two rationalities can be simultaneously nurtured. Audience: This book will be relevant to scholars, as it provides cutting-edge research, and students, since it covers the primary debates in the field, interested in resource management, regional politics, and development issues in the area. It also addresses the global debate on transboundary water management and presents an in-depth case of one of the globally most sophisticated attempts at pursuing sustainable river basin management. Finally, practitioners and policymakers would benefit greatly because all contributions have explicit policy relevance, launching suggestion on improvements in water management.

Book excerpt: This book contains 11 papers which cover a range of vital topics in the areas of water, agriculture, food security and ecosystems - the entire spectrum of developing and managing water in agriculture, from fully irrigated to fully rainfed lands. They are about people and society, why they decide to adopt certain practices and not others and, in particular, how water management can help poor people. They are about ecosystems - how agriculture affects ecosystems, the goods and services ecosystems provide for food security and how water can be managed to meet both food and environmental security objectives. This is the eighth book in the series.

Available in PDF, EPUB and Kindle. Book excerpt: To conserve water, one of the most valuable and vital resources in the world, management and public strategies, processes to reduce water consumption in industrial/commercial applications, and methods such as smart irrigation systems have been proposed. Local authorities have focused on infrastructure operations to prevent water losses and flow measurements have begun to be followed more closely. The use of greywater for partial recycling of water for household purposes and rainwater harvesting systems are being encouraged. In addition, there is more research on water conservation, its smart use, and recycling of used water being conducted. This book presents valuable scientific research on water and land management, groundwater management, and water/wastewater treatment applications for the conservation of water.
Download or read book Shifting Waterscapes Explaining Basin Closure in the Lower Krishna Basin South India written by Jean-Philippe Venot and published by IWMI. This book was released on with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progressive agricultural and water development in the Krishna Basin in South India has led to a rising over commitment of water resources and signs of basin closure are apparent during dry periods. As human consumptive uses are approaching the limits of water availability, this report focuses on the Lower Krishna Basin that bears the brunt of any intervention upstream. Capturing the process of basin closure requires an understanding of the political dimension of access to water and the scope for change. As basin closure intensifies the interconnectedness of ecosystems and water users, adjustments and management decisions result in spatial re-appropriation of water and basin-wide strategies for water management and development that start with the definition and the implementation of water allocation mechanisms are increasingly needed.

This book was released on 2019-05-13 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime and trends over time. Land use and land cover change, particularly the conversion of natural vegetation into forest plantation, the expansion of irrigated agriculture and the flow regulation due to dam operation were identified as critical drivers of flow regime alteration. Hydrograph separation using long-term hydrochemical data at seasonal scale, and hydrochemical and isotope data at event scale were performed to quantify runoff components. A novel methodology to calibrate recursive digital filters using routinely collected water quality data was developed and tested in the catchment. This method allows for estimation of daily baseflow from readily available daily streamflow data. Dominant runoff generation zones were mapped using the Height Above Nearest Drainage approach. The hydrological model STREAM was then employed, informed by the runoff generation zones mapping and the process understanding gained in the catchment, as well as remote sensing data. The study provides the basis for better operational water management in the catchment.
