The objective of IFAD/FAO consultation was to bring together experts in order to review the state-of-the-art knowledge in carbon sequestration for the land management programmes IFAD and FAO in Latin America and the Caribbean. The main objectives addressed were: how to stabilize the atmospheric concentration of CO2; how to increase agricultural productivity and reduce rural poverty; in view of the Global Mechanism for Desertification Convention, how to activiate the flow of new funds for the benefit of Convention implementation through carbon sequestration, i.e. its binding and neutralisation. It is believed that carbon stock in soils is either stable or increasing and that it is was a major source of global carbon emission, a major cause of global climate change

Carbon sequestration can be defined as the capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere. This publication contains the results of a study on the origin and background of the carbon sequestration options and the Clean Development Mechanism. The attitude and position of the key countries involved in international environmental treaties is examined, as well as the various initiatives that have been taken and the legal bases for such initiatives.

This edited book discusses how effective soil carbon management plans and policies will ultimately make agriculture more secure against climate change and soil degradation. It is focused on initiatives to enhance soil organic carbon (SOC) and sequestration by launching different schemes and programs. An approach based on practical aspects of managing SOC in agriculture is provided with clear and concise descriptions. It has more attention to successfully implement plans and policies to meet the required level of SOC restoration. The book is covering the urgent needs of plans and policies for soil management and C restoration in agricultural ecosystems which can be beneficial to food, nutrition, environment, and economy security. There is also providing a roadmap on SOC policies to encourage the use of best management practices (BMPs) for soil health and C stock restoration, and achieve the Sustainable Development Goals of the United Nations. The book is suitable for teachers, researchers, government planners and policymakers, undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and environmental sciences.

In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

This document contains the proceedings of the Subregional Workshop on Land and Water Information Systems (LWRIS) in the Caribbean, held in Barbados in October 2000. The meeting was organized by FAO Land and Water Development Division (AGL), in collaboration with the Caribbean Agricultural and Research Development Institute. LWRIS experiences in the countries are presented as well as recommendations for future collaboration in database development, reporting and exchange of information, expertise and experience in land and water management in the region and the implementation of regional projects. This includes the preparation of national and regional reports on the state of land, water and plant nutrient resources in the Caribbean for dissemination through the Caribbean Land and Water Resources Network (CLAWRENET) Web site that is linked to Web sites in the countries and with the AGL Web site.

Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause–effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.

Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Countries of the Near East vary in the type, quantity and format of the inventories of their land resources. Quite often, these data are sporadic, incomplete, out of date or based on diverse systems of land and soil classification and mapping. There is a need for the establishment of a user-friendly database on land and water Resources for each country, to be easily available at the desktop of land use planners and decision makers. Land resources information systems experiences in the countries are presented in this document, as well as recommendations for future collaboration in database development, reporting and exchange of information, expertise and experiences in land and water management in the region and the implementation of regional projects.

Includes CD-ROM on inside back cover

This publication contains a methodology and software tools for assessing carbon stocks and modelling scenarios of carbon sequestration developed and tested in pilot field studies in Mexico and Cuba. The models and tools enable the analysis of land use change scenarios in order to identify in a given area (watershed or district) land use alternatives and land management practices that can both maximise food production, soil carbon sequestration and biodiversity and minimize land degradation. The aims is to develop and implement "win-win" options that satisfy the multiple goals of farmers, land users and other stakeholders in relation to food security, carbon sequestration, biodiversity and land conservation. The publication also contains a CD-ROM including three case studies and a Soil-C program demo, program and user manual.
