Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
"Entertaining and prescient…Hockfield demonstrates how nature’s molecular riches may be leveraged to provide potential solutions to some of humanity’s existential challenges." —Adrian Woolfson, Science A century ago, discoveries in physics came together with engineering to produce an array of astonishing new technologies that radically reshaped the world: radios, televisions, aircraft, computers, and a host of still-evolving digital tools. Today, a new technological convergence—of biology and engineering—promises to create the tools necessary to tackle the threats we now face, including climate change, drought, famine, and disease World-renowned neuroscientist and academic leader Susan Hockfield describes the most exciting new developments and the scientists and engineers who helped to create them. Virus-built batteries. Cancer-detecting nanoparticles. Computer-engineered crops. Together, they highlight the promise of the technology revolution of the twenty-first century to overcome some of the greatest humanitarian, medical, and environmental challenges of our time.
Provides information in manageable chunks, which is reinforced by questions and activities that encourage students to consider the practical application of science to everyday life. This work is useful for Higher Tier GCSE students.
"An Introduction to Conservation Biology is well suited for a wide range of undergraduate courses, as both a primary text for conservation biology courses and a supplement for ecological and environmental science courses. This new edition focuses on engaging students through videos and activities, and includes new pedagogy to scaffold students' learning. Coverage of recent conservation biology events in the news-such as global climate change and sustainable development-keeps the content fresh and current"--
The Chlamydomonas Sourcebook, 3rd Edition Introduction to Chlamydomonas and Its Laboratory Use (Volume 1) The gold-standard reference?covering the basic biology of the Chlamydomonas alga and techniques for its laboratory analysis Originally published as the standalone Chlamydomonas Sourcebook, then expanded as the first volume in a three-part comprehensive gold-standard reference,?The Chlamydomonas Sourcebook: Introduction to Chlamydomonas and Its Laboratory Use?has been fully revised and updated to include a?wealth of new resources for the Chlamydomonas community. Early chapters cover current understandings of its taxonomy, ultrastructure, cell and life cycles, and nuclear and organelle genomes, followed by technique-oriented chapters covering such topics as cell culture, mutagenesis, genetic analysis, construction of mutant libraries, and protein localization using immunofluorescence. This volume presents the latest in research and best practices, making it a must-have resource for researchers and students working in plant science and photosynthesis, fertility, mammalian vision, and biochemistry; crop scientists; plant physiologists; and plant, molecular, and human disease biologists. - Remains the only complete reference to provide both the historical background and the most up-to-date information and applications on Chlamydomonas - Includes best practices for applications in research, including methods for culture, genetic analysis, genomic and transcriptomic analysis, and mutant screening - Helps researchers solve common laboratory problems, provides details on the properties of particular strains, and offers a comprehensive survey of molecular approaches - Provides a broad perspective for studies in cell and molecular biology, genetics, plant physiology, and related fields
Offering a balance of subject matter emphasis, clearly presented concepts and engaging examples, this book aims to help students gain a better understanding of ecology. Emphasis is placed on connections in nature, the importance of ecology to environmental health and services, and links to evolution.
Syngnathids are a large and diverse group of fishes, including seahorses, pipefishes, seadragons and pipehorses, These iconic and vulnerable fishes are distributed worldwide in warm temperate to tropical environments, usually in coastal shallow water. Most species are marine and strongly associated with vegetal communities or coral reefs, which provide shelter and the necessary dietary resources. Syngnathids have a unique reproductive mode with parental care, diverse brooding structures and other special characteristics that make them highly vulnerable. These iconic fishes are facing several threats, namely environmental disturbances and habitat regression. However, many of their biological, ecological and physiological characteristics have been poorly investigated and limited to a few species. Despite their vulnerability, to date, a large number of species are listed as Data Deficient (meaning they could potentially be threatened) by IUCN due to inadequate or insufficient information, mainly on distribution and/or population status. Due to the progressive regression of wild populations, long-term monitoring programs are necessary to evaluate population dynamics, fisheries, and habitat quality. On the other hand, these charismatic fishes, especially seahorses, are excellent flagship species for marine biodiversity conservation. Unfortunately, illegal harvesting and traffic of seahorses and other syngnathids is a fact, despite CITES controls. Hence, the development of new tools for fish traceability and updated policies are also necessary to reduce the threats to these fishes.
