Agriculture is now and will continue to be a key sector for low-income countries and the poor who live there. In developing countries agriculture still accounts for more than 80% of water consumption and is consequently still the largest user of water (see figures).
It is also the thirstiest sector: irrigated agriculture accounts for almost 70 percent of the global freshwater use. Unfortunately, because of leakage and inefficient irrigation systems, 60 percent of this water is lost. Limited and unreliable access to water is a determining factor in agricultural productivity in many regions, a problem rooted in rainfall variability that is likely to increase with climate change. It is expected that the world's population It is expected that the world's population will increase from 6 billion to 10 billion by midcentury, and this will lead to greatly increased demands for food, primarily from developing countries. Currently, the 17 percent of the world's cultivated land that is under irrigation produces 40 percent of the food in the world. Much of the projected increased demand for food will have to come from improved and expanded irrigation, but this will be only a partial solution. Most irrigation systems are financially out of reach for poor smallholders. Most food demand for poor people will come from areas where investment in irrigation makes no sense, with too little return from the significant capital needed. The major part of the crops produced worldwide is still grown in rain-fed agriculture and in order to improve the livelihoods of the farmers in the developing world. UNDP (2004) emphasises that more has to be done to put on employing practices that ensure higher yields per water input.

The diagram shows clearly that Finland has the highest intensity with around 24 R&D personnel per 1,000 total employment, followed by Sweden (18), Denmark (16) and Japan (15). China, South Africa and Mexico however demonstrate the lowest intensity of R&D personnel.

The overall public and private investment needs for improved water supply and sanitation and water resources management are considerable. However, at the country level, meeting such investment challenges is highly feasible and within the reach of most nations.

There are currently more than 1000 million people in the world that lacks access to an easily accessible and safe water source, such as a connection to water mains or a protected well. Instead, water access is limited or available through unprotected sources. The target, under the Millennium Development Goals, is to halve, by 2015, the proportion of people without sustainable access to safe drinking water and sanitation.
