Download or read book Global Biodiversity Assessment written by Vernon H. Heywood and published by Cambridge University Press. This book was released on 1995-11-09 with total page 1152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The survival of the Earth's biological resources is under threat from rapidly expanding human populations that are degrading the environment at an accelerating rate. Despite the increased awareness of the importance of biological diversity, the scientific foundations on which to plan conservation and development policies are still being developed. The Global Biodiversity Assessment represents an unparalleled attempt to provide an independent scientific analysis of the current issues. It assesses the present state of knowledge, identifies gaps in understanding and draws attention to those issues where scientists have reached a consensus as well as those where uncertainty has led to conflicting viewpoints and a need for further research. The Assessment provides an unprecedented source of information for decision-makers, officials, scientists and others interested in the future of the planet.
Download or read book Global assessment of forest education written by Rekola, M., Sharik, T.L. and published by Food & Agriculture Org.. This book was released on 2022-10-04 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of the forest in countries’ efforts to achieve the United Nations Sustainable Development Goals (SDGs) are widely recognized. To maximize the contribution of forests to the SDGs, a workforce trained in forestry and a broad range of other forestrelated disciplines are needed as are widespread public knowledge and understanding of forest topics. However, recent literature highlights concerns that forest education is often not meeting the fast-changing needs of the labour market and the importance of forests and of forest managers and policymakers is often under-appreciated. The scope of this report covers education and training related to forests, trees outside forests and other wooded land (i.e. natural forests, forest plantations, woodlands, agroforests and urban forests). It includes education delivered through programmes of forestry and forest sciences as well as programmes of broader scope, (e.g. natural resources management, environmental sciences). It covers all levels of formal education: primary, secondary, technical and vocational education and training (TVET) and universities and colleges (UC). This report reveals awareness of some overarching actions that would benefit forest education, including ameliorating a negative public image of professional forestrelated jobs and careers; developing better collaboration between educational institutions, the forest sector (private and public) and the general public; improving demographic diversity in the post-secondary student population; and strengthening digital readiness at all levels of education. The data collected by global survey on forest education supplemented by the six regional consultations represent a wealth of current information on the status and needs in forest education.

Download or read book A Global Assessment of the Economic Effects of Export Taxes written by David Labordew and published by Intl Food Policy Res Inst. This book was released on 2013-02-01 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study has been undertaken to understand and evaluate the potential negative consequences of export taxes which are implemented by many countries today and which are not disciplined by any international agreement. This paper uses a new detailed global dataset on export taxes at the HS6 (Harmonized System 6 level) level and the MIRAGE (Modeling International Relationships in Applied General Equilibrium) global computable general equilibrium model to assess the impact of export taxes on the world economy. We find that limitations on export taxes would have worldwide effects: the average export tax on global merchandise trade was 0.48 percent in 2007, with the bulk of these taxes imposed on energy products. The removal of these taxes would increase global welfare by 0.23 percent, which is a larger figure than the expected gains from the World Trade Organizations Doha Development Round. Both developed and emerging economies, such as China and India, would gain from such policies, even if they currently impose export taxes. Medium and small food-importing countries without market power (such as the least-developed countries) would also benefit from the elimination of export restrictions, especially during food crisis situations. Both the energy sector and the export taxes implemented by Commonwealth of Independent States countries appear to play a critical role in the overall economic impact of such a policy change. However, the fact that some countries, such as Argentina, would experience income losses due to such a policy change is a major challenge to overall positive reform in this area.
Download or read book Impacts of Large Dams A Global Assessment written by Cecilia Tortajada and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

Download or read book Economics of Land Degradation and Improvement A Global Assessment for Sustainable Development written by Ephraim Nkonya and published by Springer. This book was released on 2015-11-11 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.

Download or read book Mountain Biodiversity written by Ch. Korner and published by Routledge. This book was released on 2019-09-18 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 2002, Mountain Biodiversity deals with the biological richness, function and change of mountain environments. The book was birthed from the first global conference on mountain biodiversity and was a contribution to the International Year of Mountains in 2002. The book examines biological diversity as essential for the integrity of mountain ecosystems and argues that this dependency is likely to increase as environmental climates and social conditions change. This book seeks to examine the biological riches of all major mountain ranges, from around the world and using existing knowledge on mountain biodiversity, examines a broad range of research in diversity, including that of plants, animals, human and bacterial diversity. The book also examines climate change and mountain biodiversity as well as land use and conservation.
Download or read book Trees forests and land use in drylands the first global assessment written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-11-29 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drylands cover 41 percent of the Earth's land surface. This publication presents the results of the first global assessment of trees, forests and land use in these lands. The assessment breaks new methodological ground: it relies on the visual interpreation of freely available satellite images, carried out by more than 200 experts in a series of regional workshops. Using a tool called Open Foris ollect Earth, developed by FAO in collaboration with Google, participants gathered and analysed information for mrore than 200 000 sample plots worldwide. For each region, the report summarizes the distribution of forests, other wooded land and other land uses including grasslands, croplands, built-up areas and barren land, across all drylands and by aridity zone. It also estimates tree canopy cover, shrub cover, forest type and presence of trees outside forest. Indicatng that the global drylands contain more than one-quarter of the world's forest area, and that trees are present on 31 percent of the world's dryland area, the report provides a baseline for future monitoring and will support countries in their efforts to identify appropriate investments for the restoration and sustainable management of drylands.
Download or read book Global assessment of soil carbon in grasslands written by Dondini, M., Martin, M., De Camillis, C., Uwizeye, A., Soussana, J.-F., Robinson, T., Steinfeld, H. and published by Food & Agriculture Org.. This book was released on 2023-02-14 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils contribute to the achievement of the UN Sustainable Development Goals through carbon sequestration. By enhancing soil health and fertility, soils can play a crucial role in climate action, land degradation neutrality, and alleviating hunger. The present study provides a spatially explicit report on the state of grassland soils and can be used as a baseline for future work to explore the impacts of livestock management on soil carbon at regional, country and farm levels. Assessing the current state of grassland systems and their potential to sequester carbon in the soil is of key importance to understand the trade-offs between grassland services on food security, biodiversity conservation and climate mitigation.

Download or read book Reliability and Validity of International Large Scale Assessment written by Hans Wagemaker and published by Springer Nature. This book was released on 2020-09-03 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes and reviews the development of the quality control mechanisms and methodologies associated with IEA’s extensive program of educational research. A group of renowned international researchers, directly involved in the design and execution of IEA’s international large-scale assessments (ILSAs), describe the operational and quality control procedures that are employed to address the challenges associated with providing high-quality, comparable data. Throughout the now considerable history of IEA’s international large-scale assessments, establishing the quality of the data has been paramount. Research in the complex multinational context in which IEA studies operate imposes significant burdens and challenges in terms of the methodologies and technologies that have been developed to achieve the stated study goals. The demands of the twin imperatives of validity and reliability must be satisfied in the context of multiple and diverse cultures, languages, orthographies, educational structures, educational histories, and traditions. Readers will learn about IEA’s approach to such challenges, and the methods used to ensure that the quality of the data provided to policymakers and researchers can be trusted. An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data.
