This book deals with the topic on remote sensing monitoring of desert locust in Africa and Asia. Remote sensing monitoring of the occurrence and damage of desert locust is conducted by integrating cutting-edge technologies and methods in cross-disciplinary fields in remote sensing science, geographic information science, agronomy, plant protection, agricultural meteorology, mathematics, and computer science. The main contents include spatio-temporal data analysis and processing, desert locust breeding areas monitoring, pest migration path analysis and damage monitoring. Moreover, a desert locust remote sensing monitoring system is constructed and applied in the region of Africa and Asia countries. This book not only provides technical reference for remote sensing monitoring and application of desert locust but also serves as a research reference for scholars and graduate students engaged in agricultural remote sensing, agricultural information technology, plant protection and other related field. It will help to improve remote sensing monitoring and application of desert locust.

In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Biological and Environmental Hazards, Risks, and Disasters, Second Edition provides an integrated look at major impacts to the Earth's biosphere caused by diseases, algal blooms, insects, animals, species extinction, deforestation, land degradation, and comet and asteroid strikes, with important implications for humans. This second edition from Elsevier's Hazards and Disasters Series incorporates perspectives from the natural and social sciences to offer in-depth coverage of threats from microscopic organisms to celestial objects and their potential impacts. Contributions from expert biological, health, ecological, environmental, wildlife, physical, and health scientists, readers will gain valuable insights on damages, causality, economic impacts, preparedness, and mitigation. - Provides inter- and multi-disciplinary research accessible to both specialists and non-specialists - Includes newly added chapters on emerging hazards and risks to earth's ecosystems (land conversion and habitat loss) and human health (spread of diseases) - Contains full-color tables, maps, diagrams, illustrations, and photographs of hazardous processes

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

Fall Armyworm (FAW) (Spodoptera frugiperda) was first reported in Africa in 2016. Since then, it has become a very destructive invasive pest in sub-Saharan Africa. Its main impact is on maize crops and affects different stages of growth, from early vegetative to physiological maturity. In several countries affected by FAW attack, farmer responses have been predominantly based on the use of chemical pesticides. It is important to ensure the safe use of such pesticides by farmers, but also to promote and deploy an integrated pest management (IPM) package against FAW. Farmers need the right advice, tools and resources to sustainably manage FAW. This manual provides farmers and extension service providers easy-to-use information on how they can manage FAW in smallholder cropping systems. It provides information about modules for training trainers in FAW pest diagnostics, scouting, management and data collection. The objective of this training is to provide trainers and farmers with the knowledge and skills that will enable them to identify FAW and differentiate it from other similar pests; understand the life cycle of FAW; and, know how to monitor and manage the pest. This manual gives trainers the information they need in order to support and sustain an IPM approach for FAW management in their communities. The manual is modular and allows for updates in the future as more knowledge and solutions to manage FAW become available.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.
