Book Description
Guidebook which aims to improve MPA management by providing a framework that links the goals and objectives of MPAs with indicators that measure management effectiveness. The framework and indicators were field-tested in 18 sites around the world, and results of these pilots were incorporated into the guidebook. Published as a result of a 4-year partnership of IUCN's World Commission on Protected Areas-Marine, World Wildlife Fund, and the NOAA National Ocean Service International Program Office.

Book Description
Work is constantly reshaped by technological progress. New ways of production are adopted, markets expand, and societies evolve. But some changes provoke more attention than others, in part due to the vast uncertainty involved in making predictions about the future. The 2019 World Development Report will study how the nature of work is changing as a result of advances in technology today. Technological progress disrupts existing systems. A new social contract is needed to smooth the transition and guard against rising inequality. Significant investments in human capital throughout a person’s lifecycle are vital to this effort. If workers are to stay competitive against machines they need to train or retool existing skills. A social protection system that includes a minimum basic level of protection for workers and citizens can complement new forms of employment. Improved private sector policies to encourage startup activity and competition can help countries compete in the digital age. Governments also need to ensure that firms pay their fair share of taxes, in part to fund this new social contract. The 2019 World Development Report presents an analysis of these issues based upon the available evidence.

Book Description
The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Book Description
The World Atlas of Desertification summarises the state of scientific knowledge on the drylands of the globe. Representing in graphic form the current stage of our understanding of desertification, as well as its extent and possible solutions, it contains an extraordinary amount of information of value to students and experts alike. The Atlas clearly shows that desertification is one of the world's most pressing environmental problems, and that it is a truly global issue. Since the publication of the first edition in 1992, over 100 countries have ratified the United Nations Convention to Combat Desertification. This 2nd edition reflects major advances in our understanding of desertification over the past few years and has been thoroughly revised and expanded to almost twice its original size. Because combating desertification involves all aspects of environmental issues, this edition covers a broader range of topics, including concerns surrounding poverty, biodiversity, climate change and the availability of water. Social and economic conditions also have a major impact on the progress and control of desertification and this edition contains the latest information on population movements which result from, and lead to desertification. Desertification directly affects the livelihoods of more than one billion people who are directly dependent on the land for their survival. Using the latest updated digitised maps of desertification and fully referenced throughout, this Atlas is essential reading for everyone concerned with the drylands and their people.

Book Description
"How can agriculture contribute to the sustainable development of European cities? How can agriculture and horticulture create vital urban spaces that have new social and ecological qualities and are also economically viable? Urban Agriculture Europe is the first comprehensive, transdisciplinary publication about urban agriculture in Europe. Apart from well-known examples of urban food gardens in Western European metropolises, this volume also studies innovative forms of periurban agriculture, bringing in experiences in Eastern and Southern Europe. The contributions approach urban agriculture from the point of view of social science, the economy, agricultural ecology, and spatial planning and address the role of citizens, involved parties, and politics, as well as operational models and planning tools. Case studies from Barcelona, Dublin, Geneva, Milan, Sofia, Warsaw, and the Ruhr Metropolis allow a comparative view of European practice. Statements from involved parties and guidance for cities and regions round off the publication."--Page 4 of cover.

Book Description
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.
