National Forests of Agricultural Crops for the Wet Humid Tropics

Designing Agricultural Ecosystems for the Humid Tropics

Warmth, moisture, and constancy are the environmental factors responsible for the potentially high productivity of the humid tropical lowlands. Ironically, they are also the biome’s greatest ecological constraints to agriculture. Chemical weathering increases with temperature and is three to six times faster in the tropics than in the temperate zone (125, 250). This frequently leads to the deve...

The hydrology of the humid tropics

655 Fresh water is under pressure in the humid tropics from population growth, land use and climate change, all of which are influenced by humans. These pressures are likely to have profound consequences. Here we present a research vision for the humid tropics as an outcome of a community workshop held in Hawaii in March 2011. This report includes various perspectives from the international sci...

Soils of the Humid and Sub-humid Tropics

An Assessment of the Performance and CarcassYield of Broilers Fed Indomie Waste® in the Humid Tropics

This study was conducted using one hundred and eighty (180) day-old broiler chicks, of Anak strain to assess the levels of inclusion of indomie waste meal as a substitute for maize at 0, 25, 50, 75 and 100%. The birds were randomly assigned to dietary treatments using completely randomized design (CRD). Each treatment contained 3 replicates and each replicate had 6 birds. The study lasted for e...

Starch grain evidence for the preceramic dispersals of maize and root crops into tropical dry and humid forests of Panama.

The Central American isthmus was a major dispersal route for plant taxa originally brought under cultivation in the domestication centers of southern Mexico and northern South America. Recently developed methodologies in the archaeological and biological sciences are providing increasing amounts of data regarding the timing and nature of these dispersals and the associated transition to food pr...
