La produccion comercial de semillas de Andropogon gayanus es potencialmente factible, pero es necesario desarrollar tecnologia apropiada para la cosecha y el beneficio. Problemas inherentes al cultivo, como su altura en la madurez y el desuniforme y amplio rango de distribucion de las semillas, han dificultado la implementacion de los metodos mecanicos tradicionales de recoleccion. Ademas, las caracteristicas morfologicas de las espiculas y la presencia de aristas, espiculas esteriles y abundante pelusa ocasionan problemas particulares en el beneficio de las semillas de esta especie.

The humid tropics are exposed to an unprecedented modernisation of agriculture involving rapid and mixed land-use changes with contrasted environmental impacts. Afforestation is often mentioned as an unambiguous solution for restoring ecosystem services and enhancing biodiversity. One consequence of afforestation is the alteration of streamflow variability which controls habitats, water resources, and flood risks. We demonstrate that afforestation by tree planting or by natural forest regeneration can induce opposite hydrological changes.

In Kenya, the below-ground biodiversity (BGBD) project selected two benchmark sites for the inventory of soil biota; these included the Irangi and Ngangao forest sites in the Mount Kenya region of Embu District and the Taita Hills area of Taita Taveta District. The areas selected by the project were located in biodiversity hotspots that are supporting rare and endemic plant and animal species.
