IWMI's research agenda is organized around four priority themes covering key issues relating to land, water, livelihoods, health and environment.http://www.iwmi.cgiar.org/images/iwmi_logo_icon.jpghttp://www.iwmi.orgWed, 05 Apr 2006 00:00:01 GMTHumanenCopyright 2006 International Water Management Instituted.perera@cgiar.org (Perera Dominique)d.perera@cgiar.org (Perera Dominique)http://www.rssboard.org/rss-specificationhttp://www.iwmi.cgiar.org/Publications/Water_Policy_Briefs/PDF/WPB31.pdfWater storage has a vital role to play in improving global food security and building resilience for adaptation to climate change. A wide range of storage options are available, each with strengths and weaknesses. Because of the uncertainty associated with climate change, planners need to focus on flexibility in storage systems and give careful consideration to the sustainability, effectiveness and suitability of different storage types.Wed, 18 Nov 2009 00:14:34 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Policy_Briefs/PDF/WPB31.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Policy_Briefs/PDF/WPB31.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB128/RR128.pdfIrrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis.Wed, 07 Oct 2009 01:00:15 GMTPublicationhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB128/RR128.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB128/RR128.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB133/RR133.pdfThe study examines the global pattern and impacts of droughts through mapping several drought-related characteristics – either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.Tue, 29 Sep 2009 03:19:35 GMTPublicationhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB133/RR133.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB133/RR133.pdfhttp://www.iwmi.cgiar.org/news_room/pdf/MUS_TP52_Climbing_2009.pdfSince the early 2000s, multiple-use water services have emerged as a new approach to water services in rural and peri-urban areas in low- and middle-income countries. The concept of multiple-use services (MUS) is based on the truism that people use water from multiple sources for multiple uses. People's demand is multi-purpose. Yet, water services are usually provided by 'domestic' or 'irrigation' or 'fisheries' sub-sectors for a single use only.Tue, 08 Sep 2009 21:27:41 GMTPublicationhttp://www.iwmi.cgiar.org/news_room/pdf/MUS_TP52_Climbing_2009.pdfhttp://www.waterandfood.org/fileadmin/CPWF_Documents/Documents/CPWF_Publications/MUS_TP52_Climbing_2009.pdfhttp://www.iwmi.cgiar.org/Publications/Other/PDF/Revitalizing%20Asia%27s%20Irrigation.pdf"If we continue to go on with business as usual in the agricultural water sector, we will not have enough water to feed the expected 9 billion people on the planet in 2050". This is the assertion of 700 scientists and water professionals who contributed to the authoritative 2007 publication "The Comprehensive Assessment of Water Management in Agriculture". The 2008 food crisis has since thrust food security to the fore. World food reserves dropped significantly and millions were thrown further into poverty because of steep hikes in food prices. This crisis is likely to be replayed in future years with increasing frequency as populations rise and both climate and market forces shift more suddenly and violently.Tue, 04 Aug 2009 21:54:50 GMTPublicationhttp://www.iwmi.cgiar.org/Publications/Other/PDF/Revitalizing%20Asia%27s%20Irrigation.pdfhttp://www.iwmi.cgiar.org/Publications/Other/PDF/Revitalizing%20Asia%27s%20Irrigation.pdfhttp://www.iwmi.cgiar.org/About_IWMI/Strategic_Documents/Annual_Reports/index.aspx2008 was a momentous year for the CGIAR in that it saw the endorsement of the proposals for significant reform of the system. Whilst most of the proposed changes including the establishment of a new Fund, Consortium of Centers and the focusing of work under Mega Programs are still under detailed analysis and discussion, IWMI has been an enthusiastic supporter of the change management process and has committed significant time at senior management level towards successful outcomes. Final decisions on these will be made in December 2009.Tue, 04 Aug 2009 03:39:52 GMTPublicationhttp://www.iwmi.cgiar.org/About_IWMI/Strategic_Documents/Annual_Reports/index.aspxhttp://www.iwmi.cgiar.org/About_IWMI/Strategic_Documents/Annual_Reports/index.aspxhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB130/RR130.pdfDeclining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand.Thu, 23 Jul 2009 01:46:22 GMTPublicationhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB130/RR130.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB130/RR130.pdfhttp://www.iwmi.cgiar.org/News_Room/Newsletters/Water_Figures/PDFs/WF_Issue2_2009.pdfVariations in climatic conditions are nothing new. Farmers anywhere in Asia or Africa will tell you that some years the rains come early and last longer or that every five years or so there is a prolonged period of drought. They can also demonstrate some creative ways of adapting to those variations. What global warming will do is increase the range of variation and dramatically alter climatic conditions in some regions. Adapting to the impact these changes will have on water resources and food production will be one of the world's most serious challenges over the next 50 years.Tue, 07 Jul 2009 21:46:30 GMTPublicationshttp://www.iwmi.cgiar.org/News_Room/Newsletters/Water_Figures/PDFs/WF_Issue2_2009.pdfhttp://www.iwmi.cgiar.org/News_Room/Newsletters/Water_Figures/PDFs/WF_Issue2_2009.pdfhttp://www.iwmi.cgiar.org/Publications/Books/PDF/book-on-remote-sensing-of-global-croplands-for-food-security-1c_(2).pdfEmphasizing practical mapping technologies based on remote sensing, this book provides actionable approaches for estimating water use from irrigated and rain-fed croplands on a national, continental, or global basis. Written by leading experts working at the forefront of this critical area, it offers case studies from a variety of continents highlighting the subtle requirements of each.Tue, 30 Jun 2009 20:30:18 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Books/PDF/book-on-remote-sensing-of-global-croplands-for-food-security-1c_(2).pdfhttp://www.iwmi.cgiar.org/Publications/Books/PDF/book-on-remote-sensing-of-global-croplands-for-food-security-1c_(2).pdf http://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB129/RR129.pdfThis report explores the theory and practice of Adaptive Water Management (AWM) based on a detailed field study in the Lower Bhavani Project (LBP) in the South Indian state of Tamil Nadu. A five-step framework is used to analyze the extent to which AWM is practiced and how it could be improved. The analysis shows that the LBP system has increasingly fulfilled the criteria of a complex adaptive system over the years. The main uncertainty factor, rainfall variability, has been considered in a stepwise way during the system change cycles and has been included in the LBP system design. The study shows that in spite of contending with an imperfect irrigation system design and intense competition for water resources, water resource managers and farmers are able to adapt and continue to reap benefits from a productive agricultural system.Thu, 25 Jun 2009 03:45:34 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB129/RR129.pdfhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB129/RR129.pdf
