Climate change associated factors including temperature increases, changes in rain fall pattern and occurrence of pest and diseases negatively influence agricultural production, productivity and quality. Climate change effects particularly in region suffer persistent soil and water resource scarcity significantly increases production risk. The effects of climate change on agriculture may depend not only on changing climate condition, but also on the ability to adapt through changes in technology and demand for food.
In rural areas of developing countries, more than 70% of the population still depends on agriculture. However, economic crises, unscientific land allocation and climate change issues have hindered attempted gains in agricultural productivity and related rural development outcomes. Technology-driven breakthrough has usually pushed agriculture to the brink of another development that can affect not only plant diversity and yield, but also climatological and socio-economic outcomes.
L'agriculture intelligente face au climat (climate-smart agriculture – CSA) a comme objectifs d'être adaptée au changement climatique et de l'atténuer, tout en contribuant de manière durable à la sécurité alimentaire. Né en 2010 à l'initiative de la FAO, le concept a fait école et se décline désormais en diverses pratiques qui prennent en compte ces objectifs de manière différente. Les pratiques agroécologiques de couverture permanente du sol, par des arbres ou des cultures, sont parmi les plus courantes.
In this paper the authors present the diagnosis and re-design of farm systems as part of an innovation process involving farmers and scientists to improve the sustainability of family farms in south Uruguay. Although were selected farms with a large variation in resource endowment, they shared the main critical points of sustainability: low productivity and deteriorated soil quality.
Este artículo tiene el propósito de argumentar el grado de cohesión social que existe en la Productora de Flores Selectas de Tequexquinahuac SPR, RL, una organización integrada por 20 socios: 17 son hombres y 3 mujeres. La idea central está basada en el interés por conocer elementos que permiten organizar a actores sociales alrededor de un proyecto común; al interior de la organización propician cohesión social.
This paper describes the research path followed by a team of researchers who had investigated the nitrate problem in a case study area, and who became aware of the low impact of their data on the policy debate and on the practices that – as the research team saw it – had given rise to the problem in the first place. They embarked on a series of interactions first with participatory action researchers from the SLIM project (see Fig.
La sécurité alimentaire en Algérie semble plus que menacée par un niveau de croissance démographique incontrôlé, par la dégradation des conditions physiques du secteur de l’agriculture, par la baisse des ressources hydriques et par le retard de développement technique de l’activité. À partir d’une revue bibliographique sur la situation actuelle du secteur agricole, le texte définit ses niveaux de développement et les défis de l’avenir auxquels ce secteur sera confronté.
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.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
El objetivo de este estudio realizado en el año 2017 fue analizar el nivel de competitividad de 10 unidades familiares ubicadas en San Pedro Pochutla.
