Professor Pathmanathan Umaharan is Director of the Cocoa Research Centre and Professor of Genetics at the University of the West Indies, Trinidad and Tobago. Professor Umaharan has published extensively in the areas of plant genetic resources, genetic analysis and cocoa crop improvement.
There is a growing demand for cocoa. However, cultivation is dependent on ageing trees with low yields and increasing vulnerability to disease. There is growing concern about the environmental impact of cultivation in areas soil health and biodiversity. There is therefore an urgent need to make cocoa cultivation more efficient and sustainable to ensure a successful future. These challenges are addressed in Achieving sustainable cultivation of cocoa.
Part 1 reviews genetic resources and developments in breeding. Part 2 discusses optimising cultivation techniques to make the most of new varieties. Part 3 summaries the latest research on understanding and combatting the major fungal and viral diseases affecting cocoa. Part 4 covers safety and quality issues whilst the final part of the book looks at ways of improving sustainability, including the role of agro-forestry, organic cultivation and ways of supporting smallholders.
With its distinguished editor and international range of expert authors, this collection will be a standard reference for cocoa scientists, growers and processors.
Strong focus on conserving and exploiting genetic resources for breeding improved varieties
Detailed review of specific diseases such as witches broom as well as insect pests and nematodes
Covers key aspects of sustainability such as agro-forestry, organic cultivation and measures to support smallholders

What others are saying...
“This collection is a welcome addition to the rather scarce number of textbooks dealing with sustainable cultivation of cacao. Dealing with the basics of cacao physiology and genetic resources through to cacao breeding, cultivation and sustainability issues, the collection has many highly relevant chapters authored by experts in their field. This should be of great interest to researchers, development agencies, governments, industry specialists, and NGOs, in short anyone who is trying to improve the sustainability of this important crop”. Martin Gilmour, Global Head Agronomy, Barry Callebaut Group
