As discussed in detail in the March 2003 Issue of EM, the U.S. Environmental Protection Agency (EPA) promulgated a series of reforms to its New Source Review (NSR) permitting program starting on December 31, 2002. These reforms are commonly referred to as “NSR reform.” EPA asserts that the reforms reduce administrative burden, maximize operating flexibility, improve environmental quality, provide additional certainty, and promote administrative efficiency. Whether EPA’s assertions are accurate has been the subject of considerable debate, but the agency arguably did not achieve one of its original goals of eliminating program complexity. In fact, the reforms did not eliminate anything substantive from the NSR program.
What makes farmers try new practices?
Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others. A group of researchers at the University of Illinois wanted to know which farmers are most likely to adopt multifunctional perennial cropping systems -- trees, shrubs, or grasses that simultaneously benefit the environment and generate high-value products that can be harvested for a profit. "We surveyed farmers in the Upper Sangamon River Watershed in Illinois to learn their attitudes...
Assessment of groundwater vulnerability to nitrate pollution caused by agricultural practices
Environmental risk assessment is a step towards identification, analysis, and classification of risk factors and thus reduction of the possibility of adverse consequences. In this research, a novel approach for environmental risk assessment on groundwater pollution is applied. By combination of aquifer vulnerability DRASTIC map, pollution severity and prioritizing of the plain regions by the TOPSIS method, more sensitive regions of Qazvin aquifer in Iran are identified. In the first step, seven hydro-geological...
Sustainable Farm Practices for Rice Farming
Rice is the third-largest crop production, after sugarcane and maize. The main producers of rice are the nations of China, India, Indonesia, Bangladesh, and Vietnam. Rice is a staple crop. More than half the people in the world, about 3.5 billion people, rely on its production. Not only is rice a key source of food but it is also good source of income for many smallholder farmers. The Challenges of Rice Production After the decades of remarkable production, the rice yield has slowed down. The rice yield potential...
Knowledge of Farm Practices – The Key for Successful Farming
Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical needs: nutritious food for 9 billion people by 2050, higher and more resilient incomes, and environmental services. If...
Are Conventional Farmers Becoming Interested in Organic Practices?
Despite the fact that farming is one of the most important human activities that brings food to our tables, it contributes significantly to global pollution. Unsustainable farm practices result in the loss of biodiversity, climate changes, erosion, and the pollution of soil and water. However, when managed in a sustainable way, farming can be a source of solutions for future demands. Organic farming, as a sustainable farming practice, started like a vision of pioneers. There are now 2.3 million certified farmers...
