Evaluation of Carabid Beetle Diversity in Different Bioenergy Cropping Systems
Changes in agricultural land use as a consequence of an increased demand of energy crops have resulted in an increase of maize cropped area in many regions of Germany. The focus on maize as main biogas substrate, has led in some cases to negative ecological and environmental impacts, such as a loss of agro biodiversity reflected in a loss of field flora and fauna biodiversity. The present paper...
متن کاملAssessing Nutritional Diversity of Cropping Systems in African Villages
BACKGROUND In Sub-Saharan Africa, 40% of children under five years in age are chronically undernourished. As new investments and attention galvanize action on African agriculture to reduce hunger, there is an urgent need for metrics that monitor agricultural progress beyond calories produced per capita and address nutritional diversity essential for human health. In this study we demonstrate ho...

متن کاملnteraction of nutrient resource and crop diversity on resource use efficiency in different cropping systems
introduction conventional operations in fields, soil and water management are not efficient and loss of and damage to the environment are considerable (lal, 2000). crop diversity and understanding the complex interactions between environmental and socioeconomic factors are approaches to make better use of limited resources (tengberg et al., 1998). the most diverse ecosystems have a higher produ...
