The precise effects of natural and disturbed terrestrial systems on the atmospheric CH4 pool are uncertain. This study was conducted to quantify and compare CH4 fluxes from a variety of ecosystems in central Iowa. We investigated agricultural systems under different management practices, a hardwood forest site, native and restored prairies, and a municipal landfill. Flux measurements were obtai...

The California dairy industry generates about $4.5 billion in gross farm revenue, more than any other agricultural industry in the state. The dairy industry is also one of the most heavily regulated and supported agricultural industries in California. This article examines how the role of government has evolved in one part of the California milk marketing and pricing system. We describe the cre...

There has been much controversy over the impacts of trade liberalization on poverty. Some have argued that trade liberalizations are beneficial to the poor in developing countries, while others have argued that the gains will be captured more by the non-poor. The policies of trade liberalization in China have reduced the NPRs of some agricultural products, which cut down the welfare of its prod...

Brazil’s emergence as a primary global agricultural producer is often credited to production expansion into soils of the Brazilian savannah or Cerrado. These soils are, however, deficient in important nutrients and prone to degradation, requiring input-intensive processes that suggest a low level of productive efficiency. Employing a sequence of agricultural censuses and a biome approach for ch...

Climate change threatens agricultural productivity worldwide, resulting in higher food prices. Associated economic gains and losses differ not only by region but also between producers and consumers and are affected by market dynamics. On the basis of an impact modeling chain, starting with 19 different climate projections that drive plant biophysical process simulations and ending with agro-ec...

Agricultural production is prone to several risks which affect both producers and consumers. In order to enhance investment and achieve a sustained increase in production, coherent and integrated long-term strategies and policies are required to reduce risk aversion and build resilience among African rural producers. Furthermore, the critical importance of social protection and its complementar...
