Climate Variability, Risk and Paddy Production

Marine primary production in relation to climate variability and change.

Marine photosynthetic plankton are responsible for approximately 50 petagrams (10(15)) of carbon per year of net primary production, an amount equivalent to that on land. This primary production supports essentially all life in the oceans and profoundly affects global biogeochemical cycles and climate. This review discusses the general distribution of primary production in the sea, the processe...

Climate Variability Impacts on Land Use and Livelihoods in Drylands

This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (...

America’s water risk: Current demand and climate variability

A new indicator of drought-induced water stress is introduced and applied at the county level in the USA. Unlike most existing drought metrics, we directly consider current daily water demands and renewable daily water supply to estimate the potential stress. Water stress indices developed include the Normalized Deficit Cumulated to represent multiyear droughts by computing the maximum cumulati...

Climate variability and conflict risk in East Africa, 1990-2009.

Recent studies concerning the possible relationship between climate trends and the risks of violent conflict have yielded contradictory results, partly because of choices of conflict measures and modeling design. In this study, we examine climate-conflict relationships using a geographically disaggregated approach. We consider the effects of climate change to be both local and national in chara...
