Book Description
A comprehensive review of the honeybees of Africa on a subspecies as well as by country basis. Includes an updated multivariate analysis of the subspecies based on the merger of the Ruttner database (Oberursel) and that of Hepburn & Radloff (Grahamstown) for nearly 20,000 bees. Special emphasis is placed on natural zones of hybridisation and introgression of different populations; seasonal cycles of development in different ecological-climatological zones of the continent; swarming, migration and absconding; and an analysis of the bee flora of the continent. The text is supplemented by tables containing quantitative data on all aspects of honeybee biology, and by continental and regional maps.

Book Description
As the discipline of pollination ecology moves from describing the extent of a pollinator crisis, to identifying what can be done about it, there is a need to share and highlight very practical measures that will support sustainable crop biotic pollination services. Identifying these practices will require a mix of farmer and natural historian knowledge and scientific research. In this publication, we will outline the practices that have been so far identified, and what experiences may contribute to sharing the effectiveness of these measures under different circumstances.

Book Description
A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

Book Description
The international bee crisis is threatening our global food supply, but this user-friendly field guide shows what you can do to help protect our pollinators. The Xerces Society for Invertebrate Conservation offers browsable profiles of 100 common flowers, herbs, shrubs, and trees that support bees, butterflies, moths, and hummingbirds. The recommendations are simple: pick the right plants for pollinators, protect them from pesticides, and provide abundant blooms throughout the growing season by mixing perennials with herbs and annuals! 100 Plants to Feed the Bees will empower homeowners, landscapers, apartment dwellers — anyone with a scrap of yard or a window box — to protect our pollinators.

Book Description
This publication supports processes related to rural communities’ resilience in implementing land restoration of the Great Green Wall Programme on the ground. It serves a dual purpose of consolidating biophysical operations and socio-economic assessments, and is mainly built on five-year interventions and practical experiences gathered through Action Against Desertification. The first part of the publication is a practical manual expressly created for stakeholders, partners, non-governmental organizations and community-based organizations. Its purpose is to guide the implementation of restoration operations at scale on the ground, as well as to provide detailed practical instructions based on the successful results obtained by Action Against Desertification. The manual describes how to implement an innovative approach to the large-scale restoration of degraded land for small-scale farming. This innovative approach consists of combining enrichment planting of native woody and fodder grass species and the preparation of large-scale land for rainwater harvesting and soil permeability. The second part of the manual introduces a methodology for socio-economic assessments. This easy to-to-use approach is based on household surveys and can be used by socio-economic experts to monitor, evaluate and assess the socio-economic impacts of the large-scale restoration interventions. Household surveys are not only used for impact assessment but can potentially serve to collect useful data needed to plan a restoration intervention. Quantitative information is collected through carefully chosen standardized questions to households as samples.
