This work explores the historical effectiveness of efficiency improvements in reducing mankind’s impact on the earth. Ten activities are analyzed, including pig iron production, aluminum production, nitrogen fertilizer production, electricity generation from coal, oil, and natural gas, freight rail travel, passenger air travel, motor vehicle travel, and refrigeration. The data and analyses pres...
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...

متن کاملImproving crop productivity and resource use efficiency to ensure food security and environmental quality in China.
In recent years, agricultural growth in China has accelerated remarkably, but most of this growth has been driven by increased yield per unit area rather than by expansion of the cultivated area. Looking towards 2030, to meet the demand for grain and to feed a growing population on the available arable land, it is suggested that annual crop production should be increased to around 580 Mt and th...
