The main purpose of the overview presented in this book is to provide the international community with knowledge and tools that can be used to breed cocoa trees with greater resistance to Phytophthora. It covers pathogen diversity, epidemiological knowledge, the genetic parameters of resistance observed in the field, and practical breeding aspects. The relevance of different screening tests involving artificial inoculations and the use of molecular markers for the selection of resistant material are widely covered.
This second edition includes an updated bibliography.Astley's signature is a highly allusive, layered and self-conscious prose style, non-linear and open-ended (Gillian Whitlock, JASAL: Journal of Association for the Study of Australian Literature, 6, 2007, p. 154.)The essays offer insights into issues of language, art, gender and religion ... as well as Astley's evolving body of writing and the historical and literary context of her work (Lyn Jacobs, Australian Literary Studies v.23, n.3, 2008, p.358).
In recent years, especially with the approach of the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change in Paris in late 2015, the number of publications, conferences and meetings on climate change has been growing exponentially. Yet uncertainties remain concerning rural tropical areas where models are forecasting the onset of multiple disorders and trends are unclear. Meanwhile, the impact of climate change on the poorest communities is regularly documented, often prompting alarmist reactions. How can food security be achieved while adapting to and mitigating climate change? What are the main threats to agriculture in developing countr...

This book examines the development of innovative modern methodologies towards augmenting conventional plant breeding, in individual crops, for the production of new crop varieties under the increasingly limiting environmental and cultivation factors to achieve sustainable agricultural production, enhanced food security, in addition to providing raw materials for innovative industrial products and pharmaceuticals. This is Vol 6, subtitled Industrial and Food Crops, which consists of two parts. Included in Part I are 11 industrial plant species utilized as sources of raw materials for the production of industrial products including pulp and wood crops (acacia), fiber (cotton, jute and ramie), ...
Knowledge of Africa’s complex farming systems, set in their socio-economic and environmental context, is an essential ingredient to developing effective strategies for improving food and nutrition security. This book systematically and comprehensively describes the characteristics, trends, drivers of change and strategic priorities for each of Africa’s fifteen farming systems and their main subsystems. It shows how a farming systems perspective can be used to identify pathways to household food security and poverty reduction, and how strategic interventions may need to differ from one farming system to another. In the analysis, emphasis is placed on understanding farming systems drivers ...
