4. water : source of food security

our planet is thirsty — thirsty because it is hungry. it takes one thousand times more water to feed the human population than it does to satisfy its thirst.

water lies at the core of sustainable development concerns, and its rational and equitable management is crucial for human survival. that was one of the key messages to arise from the world summit on sustainable development2 that was held in johannesburg this summer. next year’s third world water forum in japan will address this issue in greater depth.

it is therefore fitting that this year’s world food day spotlights the role of water in food security. without water, there can be no food production. in fact, the agricultural sector is the user of 70 percent of the planet’s water supply. in a world in which per capita water availability is declining, we need to focus on appropriate water management if we are to sufficiently increase food production, with a view to reduce hunger and malnutrition, and feed a population expected to rise to 8 billion in 30 years’time.
