Tropical ecosystems sustain much of the earth’s biodiversity, provide countless natural products and services—both locally and globally—and play critical roles in the regulation of the climate and the carbon and hydrological cycles. The expansion of agriculture into tropical forest ecosystems will therefore have enormous impacts on factors such as human and animal health (Karesh et al., 2012), ...

Preserving genetic resources for next millennium is of great importance, whereas the major contribution of conserving sperms has the potential in many applications such as agriculture, biotechnology, species conservation and clinical medicine. Two major systems (liquid and frozen) of storage technologies have been developed for sperm conservation until the 20th century. The combinations of stor...

The Cannonsvifle Reservoir watershed is a major component of the unfiltered New York City water suppiy system. The voluntary, incentive-based Watershed Agricultural Program is a collaborative effort among producers, federal, state, and local organizations to address the problem of phosphorus loading effects on water quality through implementation of whole-farm plans. The effectiveness of select...

Southern Africa has high levels of food insecurity with stunting levels of more than 20% in several countries. Many countries in the region are net importers of staple food. This is partly due to low staple crop yields, with the average maize yield for the region, excluding South Africa, being around one tonne per hectare (see figure below). More than 70% of the population, and the vast majorit...
