Those who led southern African states to independence promised to redress the inequalities of settler colonialism by returning the land to the people. A generation later the rural poor are still waiting. Many lack access and full rights to agricultural land and, as developments in Zimbabwe and South Africa show, they are getting angry. Where did post-independence land reform policy go wrong?

How can integrative analysis (IA) of city systems improve understanding of the links between environmental and social problems? Can this analysis inform future decision- making? Collaborative research by the Australian National University and Mahidol University, Thailand, uses IA to analyse environmental problems, land use, and behaviour patterns in Bangkok. Do the roots of the city’s environmental problems lie in the nature of decision-making by stakeholders at every level, as the article suggests?

A University of Leeds collaborative study has probed links between environmental change and famine – two problems perceived to lie at the heart of Africa’s current crisis – in the context of another all too often linked to the continent - warfare and civil unrest. Land hunger and environmental depletion in the aftermath of war are often cited as causes of famine that in turn will lead to further conflict. Is such a chain reaction really at work? Is there an inevitable causal link between environmental degradation and violent conflict?
