In this paper, a district in Kenya is studied where there has been support for vaccination.

This paper is part of the follow-up to the workshop “Managing Agricultural Biodiversity for Sustainable Development” organized by the International Plant Genetic Resources Institute (IPGRI) for the CGIAR System-wide Genetic Resources Programme (SGRP) and hosted by the World Agroforestry Centre (ICRAF), Nairobi, Kenya (23-25 October, 2003, Nairobi, Kenya).

The use of participatory tools and methods has increased dramatically in

the recognition that sustainable NRM cannot be achieved without involving the

This study was aimed at analyzing dairy value chain in Laelay Maychew and Adwa districts of Tigray Region. The main focus was to describe and characterize different value chain actors, functions and services providers along the dairy value chain, to quantify the economic contribution of dairy value chain to actors and to investigate factors of small holder farmer’s participation in dairy value chain. To accomplish these tasks formal and informal data collection tools for both primary and secondary data.

Carbon sequestration is complicated but important at global scales.
