food and water driving 21st century african land grab

Guardian | We turned off the main road to Awassa, talked our way past security guards and drove a mile across empty land before we found what will soon be Ethiopia's largest greenhouse. Nestling below an escarpment of the Rift Valley, the development is far from finished, but the plastic and steel structure already stretches over 20 hectares – the size of 20 football pitches.

The farm manager shows us millions of tomatoes, peppers and other vegetables being grown in 500m rows in computer controlled conditions. Spanish engineers are building the steel structure, Dutch technology minimises water use from two bore-holes and 1,000 women pick and pack 50 tonnes of food a day. Within 24 hours, it has been driven 200 miles to Addis Ababa and flown 1,000 miles to the shops and restaurants of Dubai, Jeddah and elsewhere in the Middle East.

Ethiopia is one of the hungriest countries in the world with more than 13 million people needing food aid, but paradoxically the government is offering at least 3m hectares of its most fertile land to rich countries and some of the world's most wealthy individuals to export food for their own populations.

The 1,000 hectares of land which contain the Awassa greenhouses are leased for 99 years to a Saudi billionaire businessman, Ethiopian-born Sheikh Mohammed al-Amoudi, one of the 50 richest men in the world. His Saudi Star company plans to spend up to $2bn acquiring and developing 500,000 hectares of land in Ethiopia in the next few years. So far, it has bought four farms and is already growing wheat, rice, vegetables and flowers for the Saudi market. It expects eventually to employ more than 10,000 people.

But Ethiopia is only one of 20 or more African countries where land is being bought or leased for intensive agriculture on an immense scale in what may be the greatest change of ownership since the colonial era. Fist tap Dale.
