FSI scholars approach their research on the environment from regulatory, economic and societal angles. The Center on Food Security and the Environment weighs the connection between climate change and agriculture; the impact of biofuel expansion on land and food supply; how to increase crop yields without expanding agricultural lands; and the trends in aquaculture. FSE’s research spans the globe – from the potential of smallholder irrigation to reduce hunger and improve development in sub-Saharan Africa to the devastation of drought on Iowa farms. David Lobell, a senior fellow at FSI and a recipient of a MacArthur “genius” grant, has looked at the impacts of increasing wheat and corn crops in Africa, South Asia, Mexico and the United States; and has studied the effects of extreme heat on the world’s staple crops.
Nuclear Power Without Nuclear Proliferation?
The global nuclear order is changing. Concerns about climate change, the volatility of oil prices, and the security of energy supplies have contributed to a widespread and still-growing interest in the future use of nuclear power. Thirty states operate one or more nuclear power plants today, and according to the International Atomic Energy Agency (IAEA), some 50 others have requested technical assistance from the agency to explore the possibility of developing their own nuclear energy programs. This surge of interest in nuclear energy - labeled by some proponents as ‘the renaissance in nuclear power' - is occurring simultaneously with mounting concerns about the healthy of the nuclear nonproliferation regime, the regulatory framework that constrains and governs the world's civil and military- related nuclear affairs. The question then arises: is it possible to have nuclear power without nuclear proliferation? The answer is not clear, for the technical, economic, and political factors that will determine whether future generations will have more nuclear power without more nuclear proliferation are exceedingly complex and interrelated. Dr. Sagan will outline the current state of nuclear power and nuclear proliferation, before examining the weaknesses and promise of existing research on the subject. He argues that a key aspect of ensuring a safe nuclear future will be the strengthening of the NPT through "shared responsibility" for disarmament.
