UK private equity firm Emergent Asset Management launched an African Agricultural Land Fund in 2007, and has since acquired at least 100,000 ha in South Africa, Zambia, Mozambique, Swaziland and Zimbabwe. Emergent and Grainvest, a subsidiary of the South African agribusiness company RusselStone, entered into a joint venture to set up the company EmVest to operate the African Agricultural Land Fund (Agriland). In 2011, following the separation of the owners of Emergent, EmVest became an independent company, but governance of the two corporations remains convoluted. EmVest claims it controls 2,000 ha in Mozambique where it produces jatropha and 1,500-ha of disputed land in the Chokwe District (Matuba) for irrigated crops. The jatropha plantation has 560 ha planted and 800 cleared, and as of 2011, 760 ha was under production in Matuba for irrigated crops. EmVest has the right to utilize unlimited water from the canal for their irrigation needs. The land claims are unclear: disputing sources claim either 1,000 or 2,000 ha in Chokwe, and the company claims good relations with residents but the Oakland Institute quotes residents claiming only 1,000 ha belong to the company and they need the other 1,000 for their livelihoods. In 2013 Vanderbilt University in the USA divested $26 million from EmVest under pressure from the student body after the company was named in the 2011 Oakland Institute study on land grabs in Africa.
