Biomass and carbon in Terminalia amazonia plantations in the South of Costa Rica. The study was carried out in a spacing trial with an experimental design consisting of randomized complete blocks, with three treatments and three replicates. Treatments were 2 m x 2 m (2500 trees/ha), 2.5 m x 2.5 m...

Exotic tree species predominate in reforestation in tropical regions worldwide. However, some native species are suitable for plantations, providing a wider variety of products. Adequate government programs of incentives, coupled with good technical advice to farmers, are needed to stimulate refo...

There are few studies on biomass distribution for Tectona grandis plantations in Costa Rica. This paper reports the distribution of total aboveground biomass of T. grandis and its relationship with diameter at breast height (dbh), age and stand density in plantations across Costa Rica. Foliage, b...

Social conflicts with local people have caused some unsuccessful timber plantation developments in Indonesia. Company and community partnerships have provided opportunities for companies to accommodate local communities’ involvement and attempt to overcome these difficulties. Constraints in estab...

Cocoa mirids, Sahlbergella singularis and Distantiella theobroma, are the most economically important insect pests of cocoa in West and Central Africa, where they can cause up to 40% losses in cocoa yields. Sahlbergella singularis is the most common species in Cameroon and was therefore targeted ...

The humid tropics are exposed to an unprecedented modernization of agriculture involving rapid and highly-mixed land-use changes with contrasted environmental impacts. Afforestation is often mentioned as an unambiguous solution for restoring ecosystem services and enhancing biodiversity. One cons...
