Background: Up to now, efforts to help local communities out of the food-insecurity trap were guided by researcher (or other actors)-led decisions on technologies to be implemented by the communities. This approach has proved inefficient because of low adoption of the so-called improved technologies. This paper describes the strategic approaches to the development of a climate-smart village (CSV) model in the groundnut basin of Senegal.
This summary is a condensed version of the June 2011 Agriculture and Climate Change: A Scoping Report developed by a team of expert authors, in consultation with UN Framework Convention on Climate Change (UNFCCC) negotiators and other key stakeholders, and facilitated by Meridian Institute. The aim of that report was to provide independent, objective analysis on many complex issues related to agriculture and climate change. This summary provides key points for policymakers, focusing on the unique aspects of agriculture when considered in the context of climate change.
This issue of Sustentabilidade em Debate brings together three studies that complement each other with the aim of answering the same question: can the adoption of good management practices for production, conservation of natural resources and working conditions be justified economically? In other words, is the adoption or pursuit of sustainability a good deal for farmers? This question stems from a mismatch between common sense and the experience of Sebrae-MG’s Educampo Program, Rabobank and Imaflora with a large number of farmers.
Understanding spatial patterns of land use and land cover is essential for studies addressing biodiversity, climate change and environmental modeling as well as for the design and monitoring of land use policies. The aim of this study was to create a detailed map of land use land cover of the deforested areas of the Brazilian Legal Amazon up to 2008.
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of re-agro-forestation which can generate environmental benefits in addition to crop production.
Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems.
One of the most important challenges for the researchers in the 21st Century is related to global heating and climate change that can have as consequence the intensification of natural hazards. Another problem of changes in the Earth's climate is its impact in the agriculture production. In this scenario, application of statistical models as well as development of new methods become very important to aid in the analyses of climate from ground-based stations and outputs of forecasting models. Additionally, remote sensing images have been used to improve the monitoring of crop yields.
Findings from a survey on sources of income and land allocation outcomes of 578 households from 26 communities with diverse ethnic composition at distinct environmental settings in Ucayali (Peruvian Amazon) are used to contrast livelihood strategies featuring high forest and high agriculture dependency, examining whether agricultural intensification can be linked to lower deforestation. A typology of households based on their land use allocation profile was used to assess current and cumulative cleared land.
La CEPAL ha colaborado en la iniciativa La economía del cambio climático en Centroamérica (ECC CA) desde 2008 con el propósito de estimar y evidenciar los impactos de la variabilidad y del cambio climático, y propiciar la discusión sobre políticas públicas en sectores clave. Esta publicación es un resumen de los análisis de impactos potenciales del cambio climático y de las discusiones sobre opciones de políticas públicas en Guatemala generadas en el marco de la iniciativa ECC CA.
La seconde conférence triennale du Forum Global de la Recherche Agricole s’est tenue à Dakar, Sénégal du 22 au 24 mai 2003 (GFAR 2003). Le thème de la conférence était Recherche agricole et innovation rurale au service du développement durable. Le sujet de la conférence était de circonstance en raison de l’attention actuelle du monde sur les questions liées au développement durable et à la recherche en matière d’innovation des processus.
