Food security in the Asia-Pacific: climate change, phosphorus, ozone and other environmental challenges.
This is the second of two articles on challenges to future food security in the Asia Pacific region. It focuses on five mechanisms, which can be conceptualised as pathways by which pessimistic Malthusian scenarios, described in the first paper, may become manifest. The mechanisms are (1) climate change, (2) water scarcity, (3) tropospheric ozone pollution, (4) impending scarcity of phosphorus and conventional oil and (5) the possible interaction between future population displacement, conflict and poor governance. This article concludes that a sustainable improvement in food security requires a radical transformation in society's approach to the environment, population growth, agricultural research and the distribution of rights, opportunities and entitlements.
