Good beekeeping practices for sustainable apiculture
Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.
The Social Organization of Innovation
RAAKS (Rapid Rural Appraisal of Agricultural Knowledge Systems) is a participatory method that facilitates networking and communication processes. It can be used to improve the generation and use of knowledge and innovation. The set includes a CD-ROM which contents a guide to the RAAKS method, plus "windows" -- specific ways to gain a new perspective on the situation - and "tools" to be used in practice. The book can be purchased without the CD-ROM, under the title The Social Organization of Innovation.
Phylogenetics of Bees
Bees are flying insects of the order Hymenoptera closely related to wasps and ants. The ancestors of bees are assumed to be predatory wasps, which switched to pollen consumption. Further, bees co-evolved with flowering plants and divided into several species according to climatic conditions. Widely known bees are western bees Apis mellifera, and eastern bees Apis cerana. This book sheds light on features of evolution, phylogenesis, speciation, adaptation to environment, and taxonomy of bees. It will be of particular relevance to evolutionists, geneticists, taxonomists, ecologists, population geneticist, and breeders.
