I wanted to know how to practically and affordably control some of the variables that influence plant growth, such as water availability and soil fertility. I read about “wicking beds,” which are...

    23-07-2015 Climate change will have a huge impact on the world’s poorest people. Crop yields have already gone down in the tropics and are projected to drop by 15-30% by 2080 in Africa, South Asia, and Central America (Hoffman 2013). Some countries could reach a 50% loss of agricultural productivity; in...

    01-06-1985 The moringa tree, Moringa oleifera, has probably been the most popular plant in ECHO's seed bank of underutilized tropical crops. The tree is native to India but has been planted around the world and is naturalized in many locales. Moringa goes by many names. In the Philippines, where the leaves...

Pastoralists play an...

    06-04-2021 Part 2 of 4 in a series about Integrated Pest Management (IPM) Insect pests affect all forms of agricultural production, from densely planted field crops to high-value nursery plants to grains in storage. A pest management plan should start with foundational knowledge about local pest species and...
