Large-scale land acquisition projects by foreign investors, also known as “land grabbing,” raise difficult questions about the processes of valuing land in Sub-Saharan Africa that the current literature does not sufficiently explore. Land acquisitions can help developing countries like Tanzania achieve their economic and development goals. Nonetheless, it can also threaten local livelihoods and well-being due to displacement, lack of access to natural capital, and conflicts between land users.

Providing formal titles to residents in densely populated informal settlements without fuelling conflict or encouraging gentrification presents several challenges. It has been argued that, in some contexts, forms of collective tenure such as a Community Land Trust may help to overcome some of these problems. This paper analyses one attempt to legalise informal tenure arrangements, minimise relocation and prevent gentrification by introducing collective titling in an informal settlement in Nairobi.

The coastal zone represents one of the most economically and ecologically important ecosys- tems on the planet, none more so than in southern Africa. This manuscript examines the potential impacts of climate change on the coastal fishes in southern Africa and provides some of the first information for the Southern Hemisphere, outside of Australasia. It begins by describing the coastal zone in terms of its physical characteristics, climate, fish biodiversity and fisheries.
