greenhouse gases
This report presents a rapid assessment of current carbon capture and storage through a green economy lens, outlining the potential in terms of natural systems. The report underlines a far greater potential across a wider suite of natural systems. Indeed, it is a potential to not only combat climate change and climate-proof vulnerable economies, but to accelerate sustainable development and...
During the dry season of 2004–2005 the authors carried out field measurements of air pollution and meteorology in the Kathmandu Valley, Nepal, a bowl-shaped urban basin in the Himalayan foothills of Nepal. The trace gases carbon monoxide (CO) and ozone (O3) and particulates (PM10) were measured, as well as meteorological variables. In field observations, it was noted that there was...
Climate change is damaging people’s lives today. Even if world leaders agree the strictest possible curbs on greenhouse gas (GHG) emissions, the prospects are very bleak for hundreds of millions of people, most of them among the world’s poorest. This paper puts the dramatic stories of some of those people alongside the latest science on the impacts of climate change on humans....

Agriculture and climate change are inextricably linked. Agriculture is part of the climate change problem, contributing about 13.5 percent of annual greenhouse gas (GHG) emissions (with forestry contributing an additional 19 percent), compared with 13.1 percent from transportation. Agriculture is, however, also part of the solution, offering promising opportunities for mitigating GHG emissions...
Rice is grown on more than 140 million hectares worldwide and is the most heavily consumed staple food on earth. Ninety percent of the world’s rice is produced and consumed in Asia, and 90 percent of rice land is—at least temporarily—flooded. The unique semiaquatic nature of the rice plant allows it to grow productively in places no other crop could exist, but it is also the...
There is very signifcant cost-effective greenhouse gas (GHG) mitigation potential in agriculture. The mitigation potential at a range of future carbon prices is similar to the potential in the industry, energy, transport, and forestry sectors. Using economic mitigation potentials from the Intergovernmental Panel on Climate Change’s Fourth Assessment Report (IPCC AR4), the yearly...
Even with abundant evidence of the urgent need for action on climate change mitigation, there are still those who consider mitigation strategies a burden. In the agricultural sector, climate change mitigation calls for changing some agricultural and resource management practices and technologies and often requires additional investment. However, there is an opportunity in agriculture for net...
Many opportunities exist for mitigating greenhouse gas (GHG) emissions through better management of trees and soils. There is potential for both direct mitigation through better management of carbon in agricultural landscapes and indirect mitigation through reduced pressure on carbon stored in forests, peatlands, and wetlands. Effectively harnessing these opportunities will take bold action in...
Facilitating carbon sequestration in terrestrial ecosystems could provide a signifcant amount of atmospheric carbon dioxide (CO2) abatement, which is necessary to limit global temperature increases to only 2 degrees Celsius in the next century until more permanent mitigation strategies are instituted. With relatively small investments, greenhouse gas (GHG) emissions could be offset...
