This book presents essential learning approaches. It introduces educational and training activities, as well as various innovative methods aiming at the development of practical skills, in order to strengthen the continuous process of environmental education, and in particular the education for sustainable development (ESD). In doing so, it…

In March 2004, the U.K. government announced its intention to grant limited authorization for the growing of commercial genetically modified (GM) crops. This article reviews the potential liabilities that may arise from GM cropping, for environmental damage and for economic losses claimed by non-GM producers. It considers the application of the…

This article critically considers calls for the precautionary principle to inform judicial decision making in a private law context in light of the Hoffman litigation, where it is alleged that the potential for genetic contamination from genetically modified (GM) crops causes an unreasonable interference with the rights of organic farmers to use…

Current trade rules concerning cotton subsidies are intricately linked with poverty and hunger in Mali. Over half of Mali's economy and over 30 million people depend directly on cotton. It is the main cash crop and the most important source of export revenue. Cotton also plays a key role in development policies and in the fight against poverty by…

Transgenic insecticidal Bt crops are being increasingly used worldwide, and concern is increasing about resistance and their effects on nontarget organisms. The toxin acts as a weak pesticide and, hence, the effects are subtler than those of chemical biocides. However, the toxin is ever present, but concentrations vary with age of plant and plant…

This article offers the results of emergy analysis used to evaluate four different soybean production systems in Brazil that were divided into two main categories: biological models (organic and ecological farms) and industrial models (green-revolution chemical farms and herbicide with no-tillage farms). The biological models show better…

"Hoffman v. Monsanto" raises questions about the civil litigation system. Are courts appropriate institutions, and are class actions the appropriate procedure, for resolving disputes about genetically modified organisms (GMOs)? After addressing the institutional question, this article focuses on procedure. Although class actions are…

Alkaloids are part of the chemical arsenal designed to protect plants against an adverse environment. Therefore, their synthesis and accumulation are frequently induced in response to certain environmental conditions and are mediated by chemical signals, which are formed as the first responses to the external stimulus. A set of experiments using…

Plants that bear less familiar names such as switch grass, "Miscanthus," and kenaf, are not much to look at, having weathered Iowa's winter snows. But Iowa State researchers see these crops as seeds of change in alternative fuels. Rows of experimental crops line the test plots at Iowa State University's research farm. Although corn is…

The soil science and soil chemistry is incorporated into teaching materials for earth day and beyond. It revealed some of the chemical properties of the soil through color and texture and the chemical processes relevant to soils abound, including the carbon and nitrogen cycles in the soil, acidification of soils through acid deposition, leaching…

An experiment was performed on polymeric-based controlled-release agrochemicals that minimize leaching into groundwater while maintaining an adequate quantity for the desired agrochemical benefits. Gelatin gel containing inorganic Phosphorous provides controlled-release of an agrochemical where release curves show a linear relationship between…

The information contained within this guide about flora of the ferns and fern allies of the Catskill Mountains of New York State covers medical and food uses of the plants, as well as the more typical floristic data of keys, drawings, and plant descriptions. (CS)

Special issue on French dialects; discusses vocabulary related to agricultural procedures. (RL)

Reviews the development and implementation of an evaluation method for exhibitions of commercially produced hay that combines forage analysis with a procedure for visual appraisal of hay. This model is utilized to improve awareness and foster improvement and appreciation for forage quality among hay producers at county and state shows. (16…

Discusses the practice of organic farming as used in Japan. Defines the biodynamic agricultural method based on the principle of the dynamics that control life on earth from the cosmos. Argues that organic farming does not benefit from chemicals used on neighboring farms. (MDH)
