Cocoa agroforestry is perceived as potential adaptation strategy to sub-optimal or adverse environmental conditions such as drought. We tested this strategy over wet, dry and extremely dry periods comparing cocoa in full sun with agroforestry systems: shaded by (i) a leguminous tree species, Albi...

Impacts of increasing population pressure on food demand and land and water resources have sparked interest in nutrient and water balances and flows at a range of scales. In IWMI Research Report 115, it was tried for the first time to quantify rural-urban food flows for selected cities in Ghana a...

Banana and cooking banana (Musa spp.) production systems accumulate a considerable quantity of discard due to high quality demands of markets. Ripe fruits have high sugar contents, which can be easily processed to ethanol. The present study aimed to quantitatively assess the production potential ...

Lowered temperatures may reduce the root water uptake of tropical trees at high elevations through several mechanisms; however, field studies to test their relevance are lacking. We measured sap flux density (J) in small-diameter tree roots across a 2000-m elevation transect in a tropical mountai...

Agriculture and livestock production are major contributors to greenhouse gas emissions. Foragebased systems dominate much of agriculture in the tropics, providing livelihoods to farmers but also affecting local and global environments. In this paper, we attempt to answer the question, how can fa...

Carbon storage and sequestration in tropical mountain forests and their dependence on elevation and temperature are not well understood. In an altitudinal transect study in the South Ecuadorian Andes, we tested the hypotheses that (i) aboveground net primary production (ANPP) decreases continuous...

The Amazon Basin is so diverse that one could say many Amazons exist, not just one. Indeed, its diversity is considered unique in the world. Although the Basin occupies 7% of the planet’s land, it carries 25% of the world’s terrestrial biodiversity. The region is so vast, it represents one-third ...
