Responsible Investments in Land: perspectives from Tanzania and globally

From June 5-16, 2017, Landesa and the Land Portal will co-facilitate a dialogue through which a variety of stakeholders will contribute to discussion on the principles and practices of land-based investments, with a focus on the Tanzanian context. This is intended as part of the broader conversation on responsible investment in land principles, guidelines and practices that has proliferated since, at least, the 2009 food crisis and subsequent ‘land grabs’ that swept the global south. This discussion is intended to bring to the fore a grounded perspective on a conversation and debate that often remains in the conceptual or abstract. The Tanzanian context is particularly relevant because of the government’s interest to increase agricultural investment and revise the current National Land Policy with the process underway, which, among other topics, has implications for decision-making processes around land-based investments.
