Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa Rica por Piotto, D., Montagnini, F., Ugalde, L., Kanninen, M.

“…Reforestation efforts are being promoted throughout the humid tropics in response to increased areas of deforested and abandoned or degraded lands. Farmers need technical information on species performance, plantation design and management in order to make appropriate choices of species and silvicultural techniques to achieve high productivity. …”

Ecology and management of tropical secondary forest: science, people and policy: proceedings of a conference held at CATIE, Costa Rica, November 10-12, 1997 por Guariguata, Manuel R., Finegan, B.

“…The disturbance and destruction of the old-growth forests of the tropics continue to monopolize attention in international fora and the popular media, but a steadily growing land area is covered by secondary forest developing on sites which have been deforested and then abandoned by their owners. The natural process of secondary forest succession offers hope that the unique combination of goods and services provided by the original old-growth forests may be at least partially recovered. …”

Contrasting CO2 and water vapour fluxes in dry forest and pasture sites of central Argentina por Nosetto, Marcelo Daniel, Luna Toledo, Emanuel Santiago, Magliano, Patricio Nicolás, Figuerola, Patricia, Blanco, Lisandro Javier, Jobbagy Gampel, Esteban Gabriel

“…The dry forests of South America are a key player of the global carbon cycle and the regional water cycle, but they are being intensively deforested. We used eddy covariance measurements to compare the temporal patterns of CO2 and water vapour fluxes and their relationships with environmental variables in dry forest and pastures sites of central Argentina. …”

Agrobiodiversity and nutrition in traditional cropping systems - Homegardens of the indigenous Bakiga and Banyakole in southwestern Uganda. por Whitney, Cory W.

“…Households (n=102) were identified via stratified, random selection across three distinct regional ecological zones of southwestern Uganda (forest-edge, deforested areas, and wetland-edge). Their homegardens contained 209 (mean 26.8 per homegarden) useful crop species (excluding weeds and ornamentals). …”

Impacts of land use, restoration, and climate change on tropical peat carbon stocks in the twenty-first century: implications for climate mitigation por Warren, M., Frolking, S., Zhaohua, D., Kurnianto, S.

“…The climate mitigation potential of tropical peatlands has gained increased attention as Southeast Asian peatlands are being deforested, drained and burned at very high rates, causing globally significant carbon dioxide (CO2) emissions to the atmosphere. …”

Sugarcane and agroforestry farming in western Kenya por Lindell, Ida, Magnusson Kroon, Gustaf

“…Because of this, the high growth rate of the population and the economic dependence on agriculture, large areas in Kenya have been deforested. One way to reconstruct the ecosystem and compensate for the loss of resources is to design farming systems that can help safeguard these demands, e.g. agroforestry systems. …”

Understanding the impacts of land-use policies on a threatened species: is there a future for the Bornean orang-utan? por Wich, S., Gaveau, D.L.A., Abram, N, Ancrenaz, M., Baccini, A, Brend, S, Curran, L, Delgado, R.A, Erman, A., Fredriksson, G.M., Goossens, B., Husson, S.J, Lackman, I, Marshall, A.J., Naomi, A, Molidena, E, Nardiyono,Nurcahyo, A, Odom, K., Panda, A, Purnomo, Rafiastanto, A, Ratnasari, D, Santana, A.H, Sapari, I, Schaik, C.P van, Sihite, J, Spehar, S, Santoso, E, Suyoko, A, Tiju, A, Usher, G., Atmoko, S.S.U., Willems, E.P, Meijaard, E.

“…Further growth of the plantation sector should be achieved through increasing yields in existing plantations and expansion of new plantations into areas that have already been deforested. To reach this goal a large scale island-wide land-use masterplan is needed that clarifies which possible land uses and managements are allowed in the landscape and provides new standardized strategic conservation policies. …”
