In a
two–
part Water International special report on water, food, and poverty, examining 10 of the world’s major
river basins, a team of researchers say that instead of worrying about
having enough water to sustain the world’s growing demand, policymakers should be concerned with understanding how to
manage what they already have.
Introducing the special report, Simon Cook, Myles Fisher, Tassilo Tiemann, and Alain Vidal note in “Water, Food and Poverty: Global- and Basin-Scale Analysis” that the vast majority of population growth over the next few decades is expected to happen in developing countries, “where the disjunct between poverty, water and food is particularly acute.” Gaining a better understanding of water – how much we have, who uses it, and how best to use it – is essential to improving development results in the face of this demographic explosion. Water is linked with poverty and development through issues like scarcity, access, and water-related hazards (like drought, flood, and disease). But the authors conclude that water productivity – the ease or difficulty in getting water from its source to agriculture – “is by far the most important water-related constraint to improved food, income and environmental security.”
In “Water, Agriculture and Poverty in the Niger River Basin,” Andrew Ogilvie et al., paint a bleak picture of life in one of West Africa’s most important basins, writing that “[m]uch of the population in the basin suffers from extreme, chronic poverty and remains vulnerable to droughts and malnutrition.” Many of the Niger basin’s 94 million residents rely on subsistence agriculture, and most of that agriculture relies on rainwater rather than groundwater irrigation systems. Over time, the authors write, “there is little doubt that climate change will increase the strain on already-vulnerable agriculture.” Population growth will exacerbate this strain; the basin’s population is expected to increase as much as fourfold by 2050. In spite of this bleak picture, the authors conclude that “[i]mprovements in rainfed agriculture can have an important impact on poverty reduction and food security due to the large population dependent on it.”
