Africa's great 'water grab'

Claire Provost in the Guardian (UK): The banks of the Niger river, in southern Mali, have been flooded by a steady stream of foreigners. Coveted by foreign investors eager to snap up large tracts of fertile farmland, the river basin has been at the centre of a race to get hold of African land at rock-bottom prices. Meanwhile, last week, hundreds of smallholder farmers and civil society activists flocked to the same river basin for the first international conference to tackle the global rush for land.

West Africa's largest river, the Niger is thought to sustain over 100 million people as it snakes 4,180km through Guinea, Mali and Niger before emptying into Nigeria's colossal Niger Delta. In Mali, the Office du Niger is home to the vast majority of the country's largescale land deals, seen by campaigners as emblematic of the "land grabs" taking place in developing countries. Recent estimates suggest that foreign investment in Mali's limited arable land jumped by 60% between 2009 and 2010. But the potential knock-on effects of these land deals on local communities' access to water has rarely made it centre-stage.

Ongoing research from the London-based International Institute for Environment and Development seeks to redress this blindspot, honing in on how such land deals might affect water access for fishing, farming and pastoralist communities. In a policy paper out on Thursday, the IIED's Jamie Skinner and Lorenzo Cotula warn that an alarming number of African governments seem to be signing away water rights for decades, with major implications for local communities.

Investors in farmland are, understandably, after land with high growing potential – either land with lots of rainfall or land that can be irrigated. What Skinner and Cotula note is a worrying trend where governments are being rushed into signing away water rights during negotiations where they were initially only considering leasing land...
