Three major river basins flow out of Ethiopia into Sudan, constituting the Eastern Nile basin (the White Nile flows from the south). These are the Tekeze-Atbara flowing out of northern Ethiopia, the Baro-Akoba- Sobat flowing from southern Ethiopia, and the Blue Nile (Abay) sandwiched between the other two. The Blue Nile Basin, called the Abay in Ethiopia, is the largest branch of the Nile draining the Ethiopian highlands. It covers an estimated area of 311,437 square kilometers and is shared by Ethiopia and Sudan. It joins the White Nile in Khartoum, Sudan.

The tradeoffs between energy and water
have been gaining international attention in recent years as
demand for both resources mount and governments continue to
struggle to ensure reliable supply to meet sectoral needs.
As almost all energy generation processes require
significant amounts of water, and water requires energy for
treatment and transport, these two resources are
inextricably linked. This relationship is the energy-water

This working paper explores adaptation options in Central Asia. It describes the results of research conducted by a technical assistance in Central Asia. The research combined field observations with satellite-based data and created models to demonstrate the impacts of climate change on the hydrology of the Aral Sea Basin. The adaptation options explored can be summarised in three broad categories: 1) Expanding the supply of water available in the future, 2) Increasing the productivity of water and 3) Reducing future demand for water.

Climate change is at the top of the
development agenda in Central America. This region, together
with the Caribbean, is highly vulnerable to the effects of
climate change in Latin America. Climate change is
manifesting itself through higher average temperatures and
more frequent droughts that result in higher water stress,
and through the rising frequency of extreme weather events
such as tropical storms, hurricanes, floods and landslides,

Water is a fundamental platform for
economic and social development, and contributes to reducing
multiple dimensions of poverty. It is essential to food and
energy security, industrial growth, and the protection of
ecosystems. Water has been going through unprecedented
pressures as growing populations and economies have
increased demand and at the same degraded supplies. As a
result, water insecurity has become one of the greatest

The AgriTech Toolbox enables researchers and policymakers to examine how alternative agricultural practices and technologies can impact farm yields, food prices, natural resource use, hunger, malnutrition, land use and global trade in 2050, when climate change impacts may be severe. As a result, it can inform the right mix of policies and investments needed to tackle the challenges agriculture faces in the coming decades. The AgriTech toolbox models the impacts of 10 technologies on farm yields, food prices, natural resource use, hunger, malnutrition, land use and global trade.

This analysis utilizes recent hydrological and meteorological data collected from the Mizewa watershed in Fogera woreda in order to better understand the physical impact of sustainable land and watershed management (SLWM) investments. The effectiveness of the simulated conservation practices (terraces, bunds, and residue management) are evaluated using the Soil and Water Assessment Tool (SWAT) model taking into account investment decisions on different terrain types.

In this paper, we estimate the allocative inefficiency of groundwater in Pakistani agriculture and compare it across a set of farm-level constraints, using a panel dataset of rural households. The farm-level constraints include tenure, farm size, access to surface water and location on a watercourse. We use a stochastic approach, based on a system of equations to estimate both the technical efficiency of farms and the allocative efficiency of groundwater use. The allocation of surface irrigation water in Pakistan is fixed per unit of land, so its allocative inefficiency cannot be estimate.

The purpose of this study was to assess the impact of irrigation on household food security and poverty using a case study of Bwanje Valley Irrigation Scheme in Malawi. The results also showed a positive impact of irrigation on daily per capita caloric intake, with both groups of irrigating farmers realizing similar improved levels of caloric intake over farmers that did not participate in the irrigation scheme.

The International Food Policy Research Institute (IFPRI) business-asusual projections of agricultural supply and demand anticipate a rise in food prices of most cereals and meats, reversing long-established downward trends. Between 2005 and 2050, food prices for maize, rice, and wheat are projected to increase by 104, 79, and 88 percent, respectively, while those for beef, pork, and poultry will rise by 32, 70, and 77 percent, respectively.

This report cautions against an overly rigid approach to the Sustainable Development Goals (SDGs), which it argues could limit development options for poor countries, particularly in how they are able to manage critical water resources. It identifies key challenges such as setting realistic targets, carefully considering the local context to address the needs of the poor, and promoting sustainable water resources development in a way that values healthy ecosystems.
