After several decades of improvement, water quality in the United States is getting worse, and the problem is primarily caused by run-off from non-point sources, such as farms and urban development. These non-point sources have never had regulatory mandates in the Clean Water Act, and have...

Background: Agricultural soils contribute towards the emission of CH4 (mainly from paddy fields) and N2O (from N-fertilizer application), the two important greenhouse gases causing global warming. Most studies had developed the inventories of CH4 and N2O emission at the country level (larger...

This literature review examines the existing body of literature on the linkage between residential development and its impacts on the environment through air quality and greenhouse gas emissions. The research finds that, in the absence of reliable scientific studies, policy is often stimulated...

Experimental methods have recently been used to evaluate environmental policy instruments, in particular – and most suitably, it seems – emissions trading programs of various designs. Some studies have focused on domestic emissions trading programs, while others have focused on international...

This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...

Climate-economy models aiming at quantifying the costs and effects of climate change impacts and policies have become important tools for climate policy decision-making. Although there are several important dimensions along which models differ, this paper focuses on a key component of climate...

Although “cap and trade” programs for reducing greenhouse gas (GHG) emissions are often discussed as a viable program for the United States (U.S.), it is unlikely that any such program will be adopted in the near future, but there are other options available that President Obama and the...

Weather experts around the world are foreseeing a strong El Niño in 2014. In India, these developments are feared to lead to droughts. In the last 14 years, out of the four El Niño years globally, three resulted in Indian droughts. Since the 1980s, all the six droughts faced by India were in...
