Current socioeconomic drivers of land-use change associated with globalization are producing two contrasting land-use trends in Latin America. Increasing global food demand (particularly in Southeast Asia) accelerates deforestation in areas suitable for modern agriculture (e.g., soybean), severely threatening ecosystems, such as Amazonian rain forests, dry forests, and subtropical grasslands. A...

In this analysis energy inputs to crop production, emphasizing corn or maize, is compared for a series of agricultural systems of increasing complexity. Solar energy captured in corn yield is 2 to 8 times higher under intensive modern management systems than in hand or animal powered systems. The ratio of energy output to energy input is 2.14 to 1 for a modern tractor system and decreases to 0....

The advent of modern science made possible the emergence of sustained economic growth. Without growth in scientific knowledge, the productivity growth experienced during the Industrial Revolution would have eventually diminished, as did growth from previous ‘productivity revolutions’ (i.e. agriculture, expansions of trade). Yet scientific knowledge, as distinct from technology or economic produ...
