The limited available information paints a pessimistic view about groundwater resources. Due to its perceived inadequate availability, groundwater is associated with domestic use but the potential for using it for agriculture is not well reflected in the national irrigation policies.Wed, 01 Feb 2012 01:03:46 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB143/RR143.aspxhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB143/RR143.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB13.aspxGroundwater now accounts for approximately 50% of all irrigation supply in South Asia and two-thirds of supply in the grain belts of North China. Whilst the benefits of groundwater use are apparent, so too are the problems, which mainly concern issues of sustainability and water quality.Tue, 17 Jan 2012 20:29:22 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB13.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB13.aspxhttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_12-Facilitating_dialogue_for.pdfA project supported by the International Water Management Institute (IWMI) brought together local communities, hydropower authorities and government ministries to create West Africa’s first inclusive dam planning forum.Tue, 17 Jan 2012 20:27:29 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_12-Facilitating_dialogue_for.pdfhttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_12-Facilitating_dialogue_for.pdfhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP145.aspxAgriculture is at the forefront of the development objectives of the republics of Central Asia (CA). Since independence in 1991, these countries have undergone transitions from being centrally planned economies to market-oriented systems, which did not include the creation of agricultural extension systems.Tue, 17 Jan 2012 20:21:51 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP145.aspxhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP145.aspxhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB142/RR142.aspxThis study assessed the variability of flows under present and 'naturalized' basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows.Sun, 11 Dec 2011 22:43:31 GMTPublicationhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB142/RR142.aspxhttp://www.iwmi.cgiar.org/Publications/IWMI_Research_Reports/PDF/PUB142/RR142.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB7.aspxThe country has an annual rainfall between 750 and 6,000 millimeters (mm), with large spatial and temporal variation. The availability of clean drinking water is a national imperative, but agriculture consumes the bulk of available water resources. Economic development, population pressure and rising demands from different sectors are placing increasing pressure on available water resources. Climate change could aggravate this situation in Sri Lanka. There is a danger that the demand for water will outstrip supply, particularly in the Dry Zone of Sri Lanka where most irrigation schemes are located.Thu, 18 Aug 2011 23:13:26 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB7.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB7.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB8.aspxThe world's population is set to exceed nine billion by 2050, adding a third more inhabitants to the planet than today. Feeding them, taking into consideration increasing demand for diets based on fruit, vegetables and meat, will require farmers to double food production.Tue, 09 Aug 2011 03:13:51 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB8.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB8.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB6.aspxImplementing policies that encourage efficient water use, such as water allocation or pricing programmes that reflect increasing water scarcity, will motivate farmers and other water users to improve their management practices. Such efforts, in conjunction with programmes that enhance access to water by the poor, are essential to ensuring that household and global food security goals are achieved.Mon, 08 Aug 2011 01:31:40 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB6.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB6.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_12.pdfFor many of the world's poorest people, rainfall variability is a major impediment to their livelihoods. The inability to manage unpredictable changes in rainfall, and consequently runoff, is a key contributing factor to food insecurity and poverty. Frequently, periods with too much water are followed by periods with too little, and intermittent water scarcity is often a direct consequence of rainfall variability.Mon, 01 Aug 2011 01:47:02 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_12.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_12.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_%2011.pdfCurrently, over 80% of irrigated agriculture in India is supported by groundwater. India has 23 million pumps with almost a million added every year. With little control on groundwater extraction, the country faces serious groundwater depletion. Food grain production has increased as more land is brought under cultivation. High-yielding crop varieties are grown that also have high water requirements, which are being met through a boom in groundwater use.Mon, 01 Aug 2011 01:45:18 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_%2011.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_%2011.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_10.pdfRainfed agriculture produces much of the food consumed by poor communities in developing countries. It accounts for more than 95% of farmed land in sub-Saharan Africa; 90% in Latin America; 75% in the Near East and North Africa; 65% in East Asia; and 60% in South Asia. Water productivity, 'the volume of crop produced per drop', tends to be low in rainfed farming systems, while losses from evaporation are high.Mon, 01 Aug 2011 01:43:49 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_10.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_10.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_9.pdfAsia is the world's most populous continent, containing 60% of the world’s people. Africa comes second, with 12% of the world’s inhabitants. As the world's population rises from 6.8 to more than 9 billion by 2050, both these continents will face increasing demands for food and water. During the Green Revolution of the 1960s, irrigation helped India stave off famine and reduce rural poverty. Today, irrigation is stagnating. It is declining across Asia and is not widespread in Africa.Mon, 01 Aug 2011 01:41:59 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_9.pdfhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/PDF/Water_Issue_Brief_9.pdfhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP143.aspxAgriculture is the most significant contributor to Ethiopia's economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems.Mon, 01 Aug 2011 01:34:58 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP143.aspxhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP143.aspxhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP142.aspxInterest in African irrigation investment is growing. However, irrigation is not a monolithic concept, and the opportunities and risks can vary substantially by approach. To help provide an understanding of the variation, this paper builds on previous work to provide a detailed typology of irrigation systems as currently used in Ghana.Mon, 01 Aug 2011 01:34:01 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP142.aspxhttp://www.iwmi.cgiar.org/Publications/Working_Papers/working/Landing_Pages/WP142.aspxhttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_11-Multiple-use_Water_Schemes.pdfMultiple-Use water Schemes (MUS) are providing more controlled and reliable water supplies for household needs and more productive agricultural activities in the northeastern hilly regions of India and Nepal. In this region, only 5% of the existing water resources are used for economic activities.Fri, 01 Jul 2011 02:31:39 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_11-Multiple-use_Water_Schemes.pdfhttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_11-Multiple-use_Water_Schemes.pdfhttp://www.iwmi.cgiar.org/Publications/Success_Stories/PDF/2011/Issue_10-Mobilizing_Lady_Health_Workers.pdfLaunched in 1994 by Pakistan's Ministry of Health, the Lady Health Workers (LHW) program was designed as a cost-effective approach to preventing and treating common ailments at the community level.

In the areas surrounding urban centers, agriculture must compete with industry and municipal users for safe water supplies. Where wastewater collection and treatment are absent or inadequate, as in most low-income countries, natural rivers, streams and lakes are becoming polluted with urban wastewater.Fri, 01 Jul 2011 02:26:07 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB4.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB4.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB3.aspxAgricultural activities influence water quality in two main ways. First, unsustainable farming practices in upland areas usually cause soil erosion. The rain washes the loosened soil downstream causing lakes, rivers and other water bodies to silt up. Heavily silted water bodies can cause flooding and prevent dams from working effectively. Over time, the upland soil structure is damaged and depleted of nutrients.Fri, 01 Jul 2011 02:24:54 GMTPublicationshttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB3.aspxhttp://www.iwmi.cgiar.org/Publications/Water_Issue_Briefs/Landing_Pages/WIB3.aspxhttp://www.iwmi.cgiar.org/News_Room/Newsletters/Water_Matters/PDFs/Water_Matters-Issue6_2011.pdfOn September 20, 2010, IWMI held a consultative committee meeting with its partners in Sri Lanka to discuss IWMI’s research agenda for this country.
