This book was released on 2016-08-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides standards and guidelines for quantifying greenhouse gas emissions and removals in smallholder agricultural systems and comparing options for climate change mitigation based on emission reductions and livelihood trade-offs. Globally, agriculture is directly responsible for about 11% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries. Farms in the developing countries of sub-Saharan Africa and Asia are predominately managed by smallholders, with 80% of land holdings smaller than ten hectares. However, little to no information exists on greenhouse gas emissions and mitigation potentials in smallholder agriculture. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone, challenges only exacerbated by the heterogeneity of smallholder systems and landscapes. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements for quantifying GHG emissions from smallholder agriculture. Standard guidelines for use by scientists, development organizations will help generate reliable data on emissions baselines and allow rigorous comparisons of mitigation options. The guidelines described in this book, developed by the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) and partners, are intended to inform anyone conducting field measurements of agricultural greenhouse gas sources and sinks, especially to develop IPCC Tier 2 emission factors or to compare mitigation options in smallholder systems.

Available in PDF, EPUB and Kindle. Book excerpt: Processing the vast amounts of data on the Earth's land surface environment generated by NASA's and other international satellite programs is a significant challenge. Filling a gap between the theoretical, physically-based modelling and specific applications, this in-depth study presents practical quantitative algorithms for estimating various land surface variables from remotely sensed observations. A concise review of the basic principles of optical remote sensing as well as practical algorithms for estimating land surface variables quantitatively from remotely sensed observations. Emphasizes both the basic principles of optical remote sensing and practical algorithms for estimating land surface variables quantitatively from remotely sensed observations Presents the current physical understanding of remote sensing as a system with a focus on radiative transfer modelling of the atmosphere, canopy, soil and snow Gathers the state of the art quantitative algorithms for sensor calibration, atmospheric and topographic correction, estimation of a variety of biophysical and geoph ysical variables, and four-dimensional data assimilation

Download or read book Guidelines on the use of available remote sensing tools products methodologies and data to improve agricultural crop production forecast statistics in sub saharan African countries written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-03-23 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through in-depth understanding of agricultural production systems in Kenya, Senegal and Zimbabwe, this document is intended to provide guidelines on how to make use of the existing remote sensing products, methodologies and data to improve crop production forecast statistics in developing countries in general, and SSA, in particular. Despite the importance of crop production and the associated challenges most countries in SSA lack reliable and timely agricultural production forecasting systems to support decision-making at national to house-hold levels. Thus, these guidelines have been developed to facilitate the use of freely available remote sensing data and derived agro-climatic monitoring indicators and early warning products to improve crop production forecast in SSA, based on our recent experiences in Kenya, Senegal and Zimbabwe. The recent experiences accrued from working closely with the local national agricultural and meteorological centres have helped in identifying pragmatic approaches to support effective and efficiently modalities in crop production assessments and forecasting with adequate lead-time to support decision/policy making at sub-national, national and regional levels.
