This book was released on 2022-08-06 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Global Agro-Ecological Zoning version 4 (GAEZ v4), launched on 17 June 2021 uses well-established land evaluation principles to assess natural resources for finding suitable agricultural land utilization options. It is based on agro-climatic assessments, crop modelling, natural and human resources, crop statistics and water use at global scale. With the increasing complexity and intensity of environmental and social challenges an improved understanding of the biophysical determinants for agricultural management decisions including physical drivers of climate change is necessary. The main strategic goal of GAEZ v5 is to make the outputs of the system available to national entities to support wise land use decision-making. To this end, supported by a GAEZ Partnership, GAEZ v5 will provide dynamically updated AEZ information, to meet local to global level AEZ users’ needs. To refine the overall GAEZ assessment, there was an initial consultation on the data used for GAEZ v5 in December 2021. Additional recommendations for updates, refinements and extensions of approaches and modules are listed in the Appendix 1-1 (“Recommendations for further GAEZ development”) of the GAEZ v4 Model Documentation.

Book excerpt: The Global Agro-Ecological Zoning version 4 (GAEZ v4), launched on June 17th 2021, uses well-established land evaluation principles to assess natural resources for finding suitable agricultural land utilization options. It is based on agro-climatic assessments, models, natural and human resources, crop statistics and water use at global scale. With the increasing complexity and intensity of environmental and social challenges an improved understanding of the physical drivers of climate change is necessary. Consequently, a systematic and harmonized update of the global datasets is intended for the further development of GAEZ. The main strategic goal of new version of GAEZ (version 5) is to make the outputs of the system available to national entities to support wise land use decision-making. To this end, supported by the GAEZ Partnership, GAEZ v5 will provide dynamically updated AEZ information, to meet local to global level AEZ users’ need. To refine the overall GAEZ assessment, additional layers will be included in the land resources and climate database. Appendix 1 “Recommendations for further GAEZ development”) of the GAEZ v4 Model Documentation1 provides a list of potential database updates and improvements including for climate (both base-line and climate projections), land cover/land use, soil (with improved detail of processes such as land degradation) and ancillary datasets used for reporting and planning (e.g. areas reserved for environmental protection and maintenance of biodiversity, population density, livestock, administrative boundaries) GAEZ makes use of best available global spatial databases to estimate the biophysical crop production potential for over 100 crops and crop sub-types. The estimation procedures consecutively consider factors relevant for crop production over time and for different management conditions. An overview of the overall GAEZ v4 model structure and data integration is shown in Figure 1 and detailed information about the process and methodology are provided in the Model Documentation.

This book was released on 2024-03-05 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing policies to foster inclusive rural transformation processes requires better evidence on how climate change is affecting the livelihoods and economic behaviours of vulnerable rural people, including women, youths and people living in poverty. In particular, there is little comparative, multi-country and multi-region evidence to understand how exposure to weather shocks and climate change affects the drivers of rural transformation and adaptive actions across different segments of rural societies and in different agro-ecological contexts. This evidence is essential because, while climate risk and adaptive actions are context specific and require local solutions, global evidence is important for identifying shared vulnerabilities and priority actions for scaling up effective responses. This report assembles an impressive set of data from 24 low- and middle-income countries in five world regions to measure the effects of climate change on rural women, youths and people living in poverty. It analyses socioeconomic data collected from 109 341 rural households (representing over 950 million rural people) in these 24 countries. These data are combined in both space and time with 70 years of georeferenced data on daily precipitation and temperatures. The data enable us to disentangle how different types of climate stressors affect people’s on-farm, off-farm and total incomes, labour allocations and adaptive actions, depending on their wealth, gender and age characteristics.

This book was released on 2022-04-21 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper analyzes the determinants of long-term individual and community resilience for food and nutrition security in South Sudan using data from multiple sources including key informant interviews, household and community surveys, and georeferenced secondary data on climate, agricultural production, irrigation, and market access. Major agricultural development constraints as well as incidence of and responses to shocks and conflict are described. Climate-crop modeling and simulation methods are used to evaluate the constraints and to identify crop investment options. Then, a spatial typology of food and nutrition security is used to evaluate the constraints along the production-to-nutrition pathway to identify interventions that target different segments of the chain and options for improving agriculture and broader development outcomes. These are classified into production, access, and utilization efficiencies, and whether the underlying constraints are structural (i.e., level of efficiency remains the same over time) or stochastic (i.e., level of efficiency changes over time). The analysis is focused on about a dozen selected counties. The results show that development challenges are being compounded by climate change, with significant increases in the mean annual rainfall and daily maximum temperature for the warmest month. Between 1975 and 2016 for example, the mean annual rainfall in the selected counties increased by 40-111 mm/year, with a rise in the intensity of 0.2-1.3 mm per event. The daily maximum temperature for the warmest month increased by 2.0-3.2°C. If these trends (especially for temperature) continue to 2050, crop yields are projected to decline in the selected counties on average by 12-23% for sorghum, 9-18% for maize, 19-30% for groundnuts, and 16-24% for cassava. In general, there is an inverse-U-shaped the relationship between temperature and yields. While the peak of the inverse U varies by crop, time of the growing season, and other factors, crops in South Sudan are typically on the downward sloping side of the inverse U implying that increases in temperature will decrease yields (and at an increasing rate). Results of a spatial typology show that a majority (78%) of the selected counties are classified as having medium production efficiency and 22% as low production efficiency, none with high production efficiency. With respect to access to nutritious food, 55%, 29%, and 17% of the counties are classified as low, medium, and high access efficiency, respectively. And regarding the conversion of food access into nutritional status, 37%, 26%, and 37% are classified as low, medium, and high utilization efficiency, respectively. Whereas production efficiency mostly remains constant over time, (with only 24% of the counties recording substantial changes in efficiency level), access and utilization efficiency appear more volatile (with substantial changes observed in 52% of the counties). These results suggest that the access segment of the production-to-nutrition value chain is the most constraining, followed by the utilization segment. The differences in the results across counties reflect differences in development constraints across the country, which are also described. Implications of the results for building long-term individual and community resilience are discussed, in addition to areas for further research. Given the complex nature of crises facing South Sudan, our findings call for a comprehensive policy approach to address not only the urgent humanitarian crisis but also to help restore agricultural production systems as well as support communities to cope, recover, and build their vii resilience to shocks and crises. This is in line with the Partnership for Recovery and Resilience (PfRR) integrated programme framework for resilience which comprises four pillars: i) re-establish access to basic services, ii) rebuild trust in people and institutions, iii) restore productive capacities, and iv) nurture effective partnerships.

Download or read book Land Matters written by Anna Corsi and published by World Bank Publications. This book was released on 2023-02-16 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the Middle East and North Africa (MENA), land is scarce and valuable. Demand for land is projected to dramatically increase to meet the needs of a fast-growing urban population. At the same time, the supply of land is restricted by weak governance and climate factors, causing the quasi-exhaustion of cultivable land reserves. As a result, a crisis is looming. Yet, land continues to be used inefficiently, inequitably, and unsustainably. Land Matters identifies and analyzes the economic, environmental, and social challenges associated with land in the MENA region, shedding light on policy options and proposing paths to reform. It concludes that MENA countries need to act promptly, think more holistically about land, reassess the strategic trade-offs, and minimize land distortions. This report promotes a culture of open data, transparency, and inclusive dialogue on land, while filling major data gaps. These important steps will contribute to renewing the social contract, transforming the region economically and digitally, improving women’s land rights, and facilitating recovery and reconstruction in a context of dramatic social, political, and climatic transformation.

This book was released on 2023-09-06 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report examines the connection between climate change and livestock, focusing on the impacts on livestock production systems. The study explores various methodologies from the literature and analyses their application in a practical test case in the Lao People's Democratic Republic. The assessment estimates direct and indirect effects of climate change on the livestock sector by focusing on three main methodologies retrieved from the scientific literature and applied to the specific case of Lao People's Democratic Republic. The results reveal significant effects of climate change on cattle and buffaloes, the main ruminant species in the country. The findings showed significant losses in Lao People's Democratic Republic production due to heat stress affecting dry matter intake. For instance, under the representative concentration pathway 2.6 scenario, the analysis estimated a 19 percent loss in meat production and a 18 percent loss in milk production by 2085. The thermal-humidity index, used as a proxy for milk production estimation, yielded similar results. On a positive note, the study revealed that the carrying capacity and the number of potential livestock units are expected to increase from 2020 to 2080, counteracting some of the negative effects of climate change induced by heat stress. The proposed methodologies can be combined to provide a comprehensive understanding of the current and future state of the livestock population and production. While the effects may vary in different regions and production systems, the report emphasizes the importance of implementing strategies to mitigate climate change impacts. Overall, this report provides crucial information for policymakers and agencies involved with the livestock sector to guide interventions and address the challenges posed by climate change.

This book was released on 2022-05-11 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Satisfying the changing food habits and increased demand for food intensifies pressure on the world’s water, land and soil resources. However, agriculture bears great promise to alleviate these pressures and provide multiple opportunities to contribute to global goals. Sustainable agricultural practices lead to water saving, soil conservation, sustainable land management, conservation of natural resources, ecosystem and climate change benefits. Accomplishing this requires accurate information and a major change in how we manage these resources. It also requires complementing efforts from outside the natural resources management domain to maximize synergies and manage trade-offs. The objective of SOLAW 2021 is to build awareness of the status of land and water resources, highlighting the risks, and informing on related opportunities and challenges, also underlining the essential contribution of appropriate policies, institutions and investments. Recent assessments, projections and scenarios from the international community show the continued and increasing depletion of land and water resources, loss of biodiversity, associated degradation and pollution, and scarcity in the primary natural resources. SOLAW 2021 highlights the major risks and trends related to land and water and presents means of resolving competition among users and generating multiple benefits for people and the environment. The DPSIR framework was followed in order to identify the Drivers, Pressures, Status, Impact and Responses. SOLAW 2021 provides an update of the knowledge base and presents a suite of responses and actions to inform decision-makers in the public, private, and civil sectors for a transformation from degradation and vulnerability toward sustainability and resilience.

This book was released on 2023-10-24 with total page 950 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Ancient Afro-Eurasian Economies offers in three volumes the first comprehensive discussion of economic development in the empires of the Afro-Eurasian world region to elucidate the conditions under which large quantities of goods and people moved across continents and between empires. Volume 3: Frontier-Zone Processes and Transimperial Exchange analyzes frontier zones as particular landscapes of encounter, economic development, and transimperial network formation. The chapters offer problematizing approaches to frontier zone processes as part of and in between empires, with the goal of better understanding how and why goods and resources moved across the Afro-Eurasian region. Key frontiers in mountains and steppes, along coasts, rivers, and deserts are investigated in depth, demonstrating how local landscapes, politics, and pathways explain network practices and participation in long-distance trade. The chapters seek to retrieve local knowledge ignored in popular Silk Road models and to show the potential of frontier-zone research for understanding the Afro-Eurasian region as a connected space.
