In “
The Causality Analysis of Climate Change and Large-Scale Human Crisis,” published in last month’s
Proceedings of the National Academy of Sciences, authors David Zhang et al. write that changes in food supply are key indicators for the likelihood of climate change-induced conflict. Adding to the
debate on the links between climate and conflict, the authors write that their purpose was to discover the specific causal mechanisms behind the relationship by analyzing various climate- and crisis-related variables across several periods of peace and conflict in pre-industrial Europe. They found that “climate-induced agricultural decline,” as opposed to
resource scarcity caused by rapid
population growth, was the clearest indicator of impending crises. “Malthusian theory emphasizes increasing demand for food as the cause,” write the authors, “whereas we found the cause to be shrinking
food supply” – a distinction with “important implications for industrial and postindustrial societies.”
In “Using Small-Scale Adaptation Actions to Address the Food Crisis in the Horn of Africa: Going beyond Food Aid and Cash Transfers,” published in Sustainability, authors Richard Munang and Johnson Nkem advocate for community-based adaptation programs to increase resilience to food crises in the Horn of Africa. “Given that hunger and poverty are concentrated in rural areas,” the authors write, “targeting local food systems represents the single biggest opportunity to increase food production, boost food security, and reduce vulnerability.” The authors present a joint UNEP-UNDP adaptation initiative undertaken in Uganda as a framework for potential adaptation interventions in the Horn. They conclude that the initiative’s approach – pairing locally-focused sustainable farming techniques with a national-level emphasis on adaptation programs, and upscaling lessons learned from one level to the other – “will increase local buffering capacity against droughts, make communities more independent from direct aid, etc., build resilience and improve livelihoods overall.”
