Management of sedimentation in tropical watersheds

Background

The sedimentation of reservoirs is a serious problem throughout the tropics, yet most attempts to control sedimentation in large river basins have not been very successful. Reliable information on erosion rates and sources of sediments has been lacking. This paper discusses some of the limitations in estimating erosion and sedimentation and encourages development of specific sediment budgets in order to extrapolate equations and generate management procedures.

Mixed-Species Plantings in Regreening the Bare Hills: Tropical Reforestation in the Asia-Pacific Region

background

This chapter reviews the use of mixed plantations for the goal of reforestation. Mixed plantantions are a more efficient use of resources, pest resistance, and economic and ecological resilience. When establishing a new tropical reforestation program, if unaware of site conditions (and what species to choose), mixed plantations can provide greater insurance. Mixed plantations are more expensive to establish but may provide insurance against volatile markets.

Domestication of Dacryodes edulis: State-of-the-art

Background

This article provides an overview of the work being done to domesticate Dactryodes edulis, a fruit tree widespread to the humid lowlands of Central Africa. It focuses on a program in Cameroon coordinated by ICRAF that is based on a participatory approach of domesitcating D. edulis.

Deforestation and Reforestation of Latin America and the Caribbean (2001–2010)

background

This study examines contrasting forest cover change dynamics in Latin America and the Caribbean using MODIS satellite imagery. Many studies have documented deforestation, while others report forest recovery. This study seeks to analyze these trends on a large scale and connect them to environmental and population variables.

Restoration of ecosystem services and biodiversity: conflicts and opportunities

Background

Although the science and practice of ecological restoration have developed rapidly, the emerging policy focus on ecosystem services represents a significant shift in the objectives of restoration. This might result in both conflicts and opportunities. This review article explores in detail the implications of this policy shift by examining whether ecological restoration could be effective in reversing the decline of ecosystem services along with biodiversity.

Development of Soilless Culture Methods for Production of Moringa (Moringa oleifera Lam.) Root and Leaf Biomass

background

Moringa is a valuable tropical agroforestry species with a fruit rich in nutrients. This study tested soilless (hydroponic) Moringa cultivation methods given that past research on tissue culture (vegetative reproduction) has shown difficulty in transfer to soil.

Research Goals & Methods

In this study, dehulled seeds had a high germination rate (65%), whereas hulled seeds had low germination.
