Download or read book The AquaCrop model Enhancing crop water productivity written by Salman, M., García-Vila, M., Fereres, E., Raes, D., Steduto, P. and published by Food & Agriculture Org.. This book was released on 2021-11-16 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources are linked to the global challenges of food insecurity and poverty, as well as to climate change adaptation and mitigation. In line with the Sustainable Development Goals (SGD), FAO works towards several dimensions of sustainable development, including the promotion of coherent approaches to efficient, productive and sustainable water management, from farm to river basin scales. Accordingly, FAO is enhancing well-informed on-the-ground decision-making processes on water management through projects, knowledge advancement, information-sharing and tools development, such as AquaCrop, the FAO crop-water productivity model. This model assists in assessing the effects of environment (including atmospheric CO2 concentration) and management on crop production through the simulation of yield response to water of herbaceous crops. It is particularly suited to address conditions where water is a key limiting factor in crop production. In 2009, FAO officially launched AquaCrop, being the result of several years of collaborative work among scientists, water and crop specialists and practitioners worldwide, bringing together previously fragmented information on crop yields in response to water use and water deficit. AquaCrop has evolved over the different versions released since its first launch, but it always balances accuracy, simplicity and robustness. This has enabled it to remain faithful to its goal, i.e., to be a dynamic tool accessible to several types of users, mainly practitioner-type end users, in different disciplines and for a wide range of applications. In addition, AquaCrop may be considered a valuable tool by research scientists for analysis and conceptualization.

Download or read book Remote Sensing of Drought written by Brian D. Wardlow and published by CRC Press. This book was released on 2012-04-24 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Drought: Innovative Monitoring Approaches presents emerging remote sensing-based tools and techniques that can be applied to operational drought monitoring and early warning around the world. The first book to focus on remote sensing and drought monitoring, it brings together a wealth of information that has been scattered throughout the literature and across many disciplines. Featuring contributions by leading scientists, it assembles a cross-section of globally applicable techniques that are currently operational or have potential to be operational in the near future. The book explores a range of applications for monitoring four critical components of the hydrological cycle related to drought: vegetation health, evapotranspiration, soil moisture and groundwater, and precipitation. These applications use remotely sensed optical, thermal, microwave, radar, and gravity data from instruments such as AMSR-E, GOES, GRACE, MERIS, MODIS, and Landsat and implement several advanced modeling and data assimilation techniques. Examples show how to integrate this information into routine drought products. The book also examines the role of satellite remote sensing within traditional drought monitoring, as well as current challenges and future prospects. Improving drought monitoring is becoming increasingly important in addressing a wide range of societal issues, from food security and water scarcity to human health, ecosystem services, and energy production. This unique book surveys innovative remote sensing approaches to provide you with new perspectives on large-area drought monitoring and early warning.

Download or read book Yield gap analysis of field crops written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-29 with total page 82 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Global outlook on climate services in agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-09-30 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change and extreme weather events are heightening levels of acute food insecurity and food crises around the world. As the world emerges from the COVID-19 pandemic and deals with other drivers of food security, poverty and inequality, the international community is calling for a climate-resilient and sustainable recovery. Supporting the shift away from disaster response toward preventative and anticipatory action is fundamental to address the growing challenges faced by agriculture and food systems. Climate services highlight the role of science and technology in providing innovative solutions for risk reduction, effective resilience policies and adaptation planning. Underpinned by robust science and agrometeorological data, climate services and digital advisories bring tailored climate information to agricultural producers and value chain actors. But despite increasing evidence of the benefits of climate services, there are still major gaps in their development worldwide. This global assessment points to a significant gap in investment in climate services for the last mile – the small-scale farmers and most marginalized communities. Bridging this gap and scaling climate services is essential if actionable information is to be communicated in an equitable and effective manner to users, making sure no one is left behind. The report presents the latest data on the state of climate services for agricultural users with surveys from 36 countries across all FAO regions. The report’s findings have major implications for institutional frameworks to effectively target investments in resilience, preparedness and recovery. Case studies highlight additional challenges, opportunities and lessons learned from specific interventions across the climate services provision framework. Despite many challenges, climate services have demonstrable benefits to agriculture and food security by navigating agricultural producers around unpredictable and changing weather patterns. The report presents a blueprint for targeted investments to ensure that finance is effectively allocated not only to enhance the production of climate services, but also their provision, engagement and application by agricultural communities.
