Scientists Find Why Intercropping of Faba Beans with Maize Increases Yields

Chinese scientists have discovered why an agricultural practice called "intercropping' increases crop yields. The discovery could help farmers cut down the amount of chemical fertiliser they use on their crops, reducing chemical pollution in soils.


An improved method for storing maize, Togo's main cereal crop

Slightly changing the construction methods of traditional maize storage granaries can result in significantly reduced insect infestation and mildew losses for small farmers


Sustaining Vicuña Populations Through Community Involvement

The vicuña is one of the most smallest South American Camelids
and is probably linked to its cousin the Alpaca. Vicuña are distributed
along five countries in South America, which include Argentina, Peru,
Bolivia, Chile and Ecuador.


Sweden and UNEP Team Up to Help Developing Countries Phase Out of Ozone-Depleting HCFCS

On 16th of November 2007, a new chapter was opened in the work of Governments and international organizations to help rid the world of a group of chemicals which, besides depleting the ozone layer, are also powerful greenhouse gases.


Foundation for Otters

Otters have almost totally disappeared in Western Europe and the number of this species is gradually decreasing today all over Europe. Poaching is on the rise, and populations are fragmented and isolated. Today, the main causes in Western countries are the destruction of wetland habitats and water pollution.


Policy Dynamics and Alley Farming Adoption in West and Central Africa

Traditional agricultural practice in Africa involves shifting cultivation in which cultivated land is left to fallow so that soil fertility is restored. However, increased land demand from a growing population is placing constraints on this practice. Alternatives to this farming practice have become inevitable.


Prospects for suppressing dengue transmission by means of biological agents.

A biological agent that would most effectively reduce risk of dengue transmission would act against the adult stage of the vector mosquito. Beyond anecdotal references to swallows, dragonflies and ants, however, no biological agent has yet been developed specifically for use against a domestic vector of an arbovirus.


Using carbon emission credits to promote environmentally sensitive agriculture

Forests and tree plantations are seen as part of the solution since they store carbon at a rate 20 to 100 times more per acre than pastures and croplands. The substitution of composting and other organic techniques for fertilizers and pesticides on tree plantations also allows for increased carbon storage.


Bole, Ghana: Research and development of the shea tree and its products

In recent years the shea tree has gained importance as an economic crop because of the heavy demand for its butter, both locally and internationally. In recognition of the need to find substitutes for the rather expensive cocoa products, and to maximize economic exploitation of the vast shea resource in Ghana, the Cocoa Research Institute of Ghana (CRIG) initiated scientific research into the cultivation and processing of shea nuts.


The Santos Beaches Recovery Program

Sewage discharge from illegal drainage pipes caused pervasive coastal and water pollution in the city of Santos, Brazil. Erosion of the local tourist industry then caused a deep recession in the 1970s.
