Book Description
Banana one of the most popular consumed fruits in the tropical and sub-tropical region. Most of the edible bananas present now a days are derived solely from Musa accuminata Colla or Musa balbisiana Colla or a hybrid between the two wild diploid species. The main objective of this research work is to provide an overview of various pest and diseases affecting Banana in South India. Diseases and pests of edible banana became problems when certain genotypes were grown as monocultures. Fusarium wilt and Sigatoka leaf spot were also affect the banana production in South-India. Bacterial wilt and Xanthomonas wilt are other bacterial diseases affecting the banana production. Bunchy top and bract mosaic are damaging virus diseases, which have a limited distribution at present. Virus diseases mosaic and streak are less damaging, but more widespread. Pre- and post-harvest diseases of fruit also cause losses. The burrowing nematode is the most important root parasite of banana, and the most damaging banana insect pest is the rhizome-attacking banana weevil. Genetic engineering and other biotechnology-based approaches could produce better diseases tolerant varieties. Chemical control has been employed successfully in the past to counter pests and pathogens, but resistance to fungicides and pesticides is becoming a major issue. Biological control methods are being employed more often in integrated pest management programmes could offer a promising result to address this issue.

Book Description
This open access book asks just how climate-smart our food really is. It follows an average day's worth of food and drink to see where it comes from, how far it travels, and the carbon price we all pay for it. From our breakfast tea and toast, through breaktime chocolate bar, to take-away supper, Dave Reay explores the weather extremes the worlds farmers are already dealing with, and what new threats climate change will bring. Readers will encounter heat waves and hurricanes, wildfires and deadly toxins, as well as some truly climate-smart solutions. In every case there are responses that could cut emissions while boosting resilience and livelihoods. Ultimately we are all in this together, our decisions on what food we buy and how we consume it send life-changing ripples right through the global web that is our food supply. As we face a future of 10 billion mouths to feed in a rapidly changing climate, its time to get to know our farmers and herders, our vintners and fisherfolk, a whole lot better. Dave Reay is Professor of Carbon Management at the University of Edinburgh, UK. He has studied climate change for over 20 years, from warming impacts in the Southern Ocean, through carbon fluxes in forests, to greenhouse gas emissions from wetlands and agriculture. In 2018 he received the Chancellors Award for Teaching for his work in climate change education. His latest project involves managing a large area of coastal land in Scotland to regrow native tree species and trap a lifetimes carbon.

Book Description
A survey of diseases and pests was made in Burundi, Rwanda, Eastern Zaire, Prmba, Zanzibar, mainland Tanzania and Uganda. the main varietiesgrown are the East African beer and cooking bananas (AAAs) present in the area for centuries and the more recently planted Pisang awak, Ney poovan and Gros Michel. Bluggoe and Cavendish varieties are also widely planted. All of the more recently planted varieties except Cavendishwere being attacked by Panama disease in all countries. These varieties were planted for their tolerance to drought, poorer soils, borers and nematodes and good beer-making qualities.

Book Description
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
