Sesbania sesban improved fallows in eastern Zambia: Their inception, development and farmer enthusiasm

Background

In eastern Zambia, nitrogen deficiency is a major limiting factor for increased food production. Soil fertility has been declining because of nearly continuous maize (Zea mays) cultivation with little or no nutrient inputs. The use of short-duration tree fallows was one of several agroforestry options hypothesized to restore soil fertility. This study reports on long-term trials with Sesbania sesban in field station and farm trials.

Paying for Biodiversity Conservation Services in Agricultural Landscapes

background

This document describes the genesis for the World Bank GEF project from 2002-2007 to implement payments for ecosystem services for silvo-pastoral systems in Colombia, Nicaragua, and Costa Rica. The payments were designed to compensate for biodiversity services: international donor money would be exchanged for the international environmental service of biodiversity.

Uses, Management and Economic Potential of Garcinia kola and Ricinodendron heudelotii in the humid lowlands of Cameroon

Background

This article describes two common fruit and medicinal trees (non-timber) that grow in secondary forests in the lowlands of Cameroon. The trees are found to have a mixed effect in an agroforestry environment; sometimes they improve crop production, sometimes they do not. Fruit are consumed by families and sold in markets.

Special Report of Captain George P. Ahern, Ninth U.S. Infantry, in Charge of Forestry Bureau, Philippine Islands, Covering the Period from April, 1900, to July 30,1901

background

This 139-page report outlines the state of the Spanish colonial Forestry Bureau at time of arrival of US forces in the Philippines (~1900), and reforms instituted by Captain Ahern. He describes the timber business in the Philippines including the state of the forested lands, species exploited, and volumes exported. At that time, 160 species of native trees were exported, but the Forestry Bureau knew of 665 native tree species. Ahern suggests trying to find a use for them to make timber extraction more profitable. Samples of 100 species were sent to the US for exhibition.
