Download or read book Adaptation to Climate Change in Agriculture written by Toshichika Iizumi and published by Springer Nature. This book was released on 2019-10-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights state-of-the-art research and practices for adaptation to climate change in food production systems (agriculture in particular) as observed in Japan and neighboring Asian countries. The main topics covered include the current scientific understanding of observed and projected climate change impacts on crop production and quality, modeling of autonomous and planned adaptation, and development of early warning and/or support systems for climate-related decision-making. Drawing on concrete real-world examples, the book provides readers with an essential overview of adaptation, from research to system development to practices, taking agriculture in Asia as the example. As such, it offers a valuable asset for all researchers and policymakers whose work involves adaptation planning, climate negotiations, and/or agricultural developments.

Download or read book Sub field Crop Yield and Yield Stability Analysis with Multi source Datasets and Advanced Crop Simulation Model written by Guanyuan Shuai and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of precision agriculture technology and big data allows farmers to improve the sustainability in crop production by improving profit and minimizing environmental loss. However, knowledge about managing sub-field yield variations over the years (yield stability) is less understood, so the actual adoption rate of precision technology is low, especially in small farms. The overarching goal of this dissertation was to evaluate the spatial and temporal variability of maize and soybean yields related to landscape characteristics and management in the U.S. Midwest (Chapter 1).Chapter 2 aims to develop a yield stability map using satellite images for ten maize/soybean main production states in the Corn Belt. This study uses Landsat images over eight years and common land unit polygons as the primary dataset to classify each field into stable high, stable low, and unstable areas. I further quantified nitrogen (N) balance and loss and associated monetary and environmental loss for each yield stability class. Across a wide range of crop growth environments, this large-scale analysis has shown reliable and consistent subfield yield patterns that could improve fertilizer application.Chapter 3 investigates the potential of these low-yielding areas in supporting biofuel crop (switchgrass) production to replace current crops and subsequent improvement in soil and climate change. I also proposed planting a cover crop, rye, to evaluate the effect on the soil nitrate level. The switchgrass and cover crop production were simulated by the Systems Approach to Land Use Sustainability (SALUS) model, which also modeled soil organic matter dynamics under the proposed and current (continuous maize or maize/soybean rotation) scenarios. Benefits such as reduced soil nitrogen, improved soil structure, and higher heterogeneity of landscape composition demonstrate the potential of yield stability maps to support sustainable agricultural production. In Chapter 4, I combined the yield stability maps with remote sensing images to improve the maize yield prediction at subfield scale. In this study, I first made a further division in the unstable area by including the topographic features and modeled cumulative crop water stress. The modeled water stress was combined with Landsat Analysis Ready Dataset (ARD) to predict maize yield using a random forest algorithm. Results showed that incorporating the modeled water stress with vegetation index derived from Landsat images produced the highest accuracy in estimated maize yield compared to satellite images alone. This work emphasized the yield stability map's ability to capture subfield spatial variations of soil and plant available water stress information.Chapter 5 compares the accuracy in yield level estimation between yield stability maps and high-resolution Planet images (3-m, bi-weekly) and analyzes the temporal changes of spatial variation of crop conditions during the growing season. The yield stability maps could predict similar maize yield levels in stable zones compared to satellite images. The temporal analysis in the spatial variation indicated greater changes in the field at the beginning or end of the season, while spatial patterns of crop growth dynamics remain stable in the mid-season. Early- or late-season changes did not always impact the final yield. This analysis provided an in-depth analysis of the in-season image so farmers could better monitor crops in real-time. Conclusions from these research projects and recommendations on interpretation yield and satellite images for sustainable production are presented in Chapter 6.

Download or read book The State of Food and Agriculture 2021 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-11-23 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic exposed the vulnerability of agrifood systems to shocks and stresses and led to increased global food insecurity and malnutrition. Action is needed to make agrifood systems more resilient, efficient, sustainable and inclusive. The State of Food and Agriculture 2021 presents country-level indicators of the resilience of agrifood systems. The indicators measure the robustness of primary production and food availability, as well as physical and economic access to food. They can thus help assess the capacity of national agrifood systems to absorb shocks and stresses, a key aspect of resilience. The report analyses the vulnerabilities of food supply chains and how rural households cope with risks and shocks. It discusses options to minimize trade-offs that building resilience may have with efficiency and inclusivity. The aim is to offer guidance on policies to enhance food supply chain resilience, support livelihoods in the agrifood system and, in the face of disruption, ensure sustainable access to sufficient, safe and nutritious food to all.

This book was released on 2018-06-21 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.
