Through a range of local initiatives and collaborations developed over the past 15 years, Tanzania’s Yaeda Valley, the primary remaining home territory for the last community of Hadzabe hunter-gatherers, has become a model for community-based conservation. 

Large-scale land acquisitions have increased in scale and pace due to changes in commodity markets, agricultural investment strategies, land prices, and a range of other policy and market forces. The areas most affected are the global “commons” – lands that local people traditionally use collectively — including much of the world’s forests, wetlands, and rangelands. In some cases land acquisition occurs with environmental objectives in sight – including the setting aside of land as protected areas for biodiversity conservation.

 One of the most wellknown biofuel investments was that of Bioshape, which acquired approximately 34,000 ha in Kilwa District for the cultivation of jatropha.
