Book excerpt: Comprehending and forecasting planted forests yields are actually a challenge for forest managers, mainly due to combined, and generally misunderstood, influences of space-time weather oscillations, pests, abiotic disturbances and lack of management practices.Aiming to provide future stochastic production estimations for risk assessment and KPIu2019s for current productivity, considering distinctly climate and forest management effects, we developed a framework named GPT (Portuguese acronym for total productivity management), that integrates a soil and climate database (from 1980 up-to-date), a process-based ecophysiological model (an improved version of 3-PG), yield gaps concept, Monte Carlo approach, probabilistic analysis, forest inventory and remote sensing.This framework was applied to a group of Eucalyptus plantation, ranging from 2 to 4 years old, in northeast Sao Paulo, Brazil, that suffered from defoliation and sporadic mortality due to an intense dry period in 2017. Landsat-8 imagery timeseries were used to estimate different levels of defoliation and eventual mortality.Reference productivity (a timeless reference given by the framework) for this plantation was 270 mu00b3/ha (year 6). Optimist and pessimist scenarios (from probabilistic analysis) ranged from 301 to 223 mu00b3/ha. Actual weather conditions impacted negatively the attainable productivity by 5,4%. Defoliation and mortality impacts over future yield varied from -2% up to -20%, considering optimistic and pessimistic future scenarios, with a most likely estimation of -9,1%. This approach was proven to be helpful for forest managers to predict and prevent yield losses, manage risks and take decisions considering the dynamics of forest growth under changing scenarios.

Book excerpt: To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Available in PDF, EPUB and Kindle. Book excerpt: In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

Book excerpt: As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world's population. This study assesses how serious the danger to food security might be and suggests some steps policymakers can take to remedy the situation.Using various modeling techniques, the authors project 15 different future scenarios for food security through 2050. Each scenario involves an alternative combination of potential population and income growth and climate change. The authors also examine the specific test case of a hypothetical extended drought in South Asia, to demonstrate the possible effects of increased climate variability on a particular world region. They conclude that the negative effects of climate change on food security can be counteracted by broad-based economic growthparticularly improved agricultural productivityand robust international trade in agricultural products to offset regional shortages. In pursuit of these goals, policymakers should increase public investment in land, water, and nutrient use and maintain relatively free international trade. This inquiry into the future of food security should be of use to policymakers and others concerned with the impact of climate change on international development.

Book excerpt: Unless action is taken now to make agriculture more sustainable, productive and resilient, climate change impacts will seriously compromise food production in countries and regions that are already highly food-insecure. The Paris Agreement, adopted in December 2015, represents a new beginning in the global effort to stabilize the climate before it is too late. It recognizes the importance of food security in the international response to climate change, as reflected by many countries prominent focus on the agriculture sector in their planned contributions to adaptation and mitigation. To help put those plans into action, this report identifies strategies, financing opportunities, and data and information needs. It also describes transformative policies and institutions that can overcome barriers to implementation. The State of Food and Agriculture is produced annually. Each edition contains an overview of the current global agricultural situation, as well as more in-depth coverage of a topical theme."

Book excerpt: Confronting Climate Uncertainty in Water Resources Planning and Project Design describes an approach to facing two fundamental and unavoidable issues brought about by climate change uncertainty in water resources planning and project design. The first is a risk assessment problem. The second relates to risk management. This book provides background on the risks relevant in water systems planning, the different approaches to scenario definition in water system planning, and an introduction to the decision-scaling methodology upon which the decision tree is based. The decision tree is described as a scientifically defensible, repeatable, direct and clear method for demonstrating the robustness of a project to climate change. While applicable to all water resources projects, it allocates effort to projects in a way that is consistent with their potential sensitivity to climate risk. The process was designed to be hierarchical, with different stages or phases of analysis triggered based on the findings of the previous phase. An application example is provided followed by a descriptions of some of the tools available for decision making under uncertainty and methods available for climate risk management. The tool was designed for the World Bank but can be applicable in other scenarios where similar challenges arise.

Available in PDF, EPUB and Kindle. Book excerpt: Governments in developing countries have been increasingly involved in the support of agricultural (crop and livestock) insurance programs in recent years. In their attempts to design and implement agricultural insurance, they have sought technical and financial assistance from the international community and particularly from the World Bank. One of the recurrent requests from governments regards international experience with agricultural insurance, not only in developed countries, where in some cases agricultural insurance has been offered for more than a century, but also in middleand low-income countries. Governments are particularly interested in the technical, operational, financial, and institutional aspects of public support to agricultural insurance. 'Government Support to Agricultural Insurance' informs public and private decision makers involved in agricultural insurance about recent developments, with a particular focus on middle- and low-income countries. It presents an updated picture of the spectrum of institutional frameworks and experiences with agricultural insurance, ranging from countries in which the public sector provides no support to those in which governments heavily subsidize agricultural insurance. This analysis is based on a survey conducted by the World Bank s agricultural insurance team in 2008 in 65 developed and developing countries. Drawing on the survey results, the book identifies some key roles governments can play to support the development of sustainable, affordable, and cost-effective agricultural insurance programs.

Book excerpt: Artificial intelligence (AI) has grown in presence in asset management and has revolutionized the sector in many ways. It has improved portfolio management, trading, and risk management practices by increasing efficiency, accuracy, and compliance. In particular, AI techniques help construct portfolios based on more accurate risk and return forecasts and more complex constraints. Trading algorithms use AI to devise novel trading signals and execute trades with lower transaction costs. AI also improves risk modeling and forecasting by generating insights from new data sources. Finally, robo-advisors owe a large part of their success to AI techniques. Yet the use of AI can also create new risks and challenges, such as those resulting from model opacity, complexity, and reliance on data integrity.

Book excerpt: Annotation. Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.
