Forest harvest alters natural nutrient cycles, which is reflected in stream water run-off from harvested catchments. Nitrate is an essential nutrient for plant growth, but increased concentrations in rivers, lakes, and oceans have contributed to eutrophi...

Excessively high levels of post-harvest loss often are a feature of agricultural systems dominated by small-holder farmers. However, this situation is something of a paradox, as technologies exist that have been shown in field demonstrations to substanti...
