En este artículo se abordan los programas institucionales implementados en contextos locales y la acción colectiva para el desarrollo de alimentos con arraigo territorial, desde el enfoque de los Sistemas Agroalimentarios Localizados (Sial). Se analiza el caso de un programa piloto para la producción de cuitlacoche (Ustílago Maydis sp.) en el estado de Tlaxcala, México, y dos microempresas familiares involucradas en la producción de ese hongo utilizado en la alimentación humana.
La agricultura tiene una importancia estratégica en la agenda para el desarrollo. Es una de las principales fuentes de empleo, un motor del desarrollo económico y un sector cuyo crecimiento incide ampliamente en la reducción de la pobreza y en la erradicación del hambre.
Este texto presenta un recuento de los logros alcanzados mediante un conjunto de políticas públicas que se han aplicado a lo largo del tiempo en la Argentina, muchas de las cuales se continúan y coordinan en el marco del Programa Agricultura Inteligente. Esas políticas han permitido encontrar respuestas a preocupaciones como el aumento de la productividad, los efectos del cambio climático, el uso adecuado de los recursos fundamentales del agua y la tierra y la menor utilización de energías altamente contaminantes, entre otras.
Agricultural biotechnology and, specifically, the development of genetically modified (GM) crops have been controversial for several reasons, including concerns that the technology poses potential negative environmental or health effects, that the technology would lead to the (further) corporatization of agriculture, and that it is simply unethical to manipulate life in the laboratory. GM crops have been part of the agricultural landscape for more than 15 years and have now been adopted on more than 170 million hectares (ha) in both developed countries (48%) and developing countries (52%).
For millennia, humans have modified plant genes in order to develop crops best suited for food, fiber, feed, and energy production. Conventional plant breeding remains inherently random and slow, constrained by the availability of desirable traits in closely related plant species. In contrast, agricultural biotechnology employs the modern tools of genetic engineering to reduce uncertainty and breeding time and to transfer traits from more distantly related plants.
The agro-ecosystem is a system composed of population, natural resources and economic activities related in a dynamic interaction in terms of socio-ecological and socio-economic relations conditioned by endogenous and exogenous factors. With time, the agro-ecosystem undergoes changes. By analysing the agro-ecosystem dynamics over a period of time, we can plan the agro-ecosystem for higher level of production and productivity, achieving higher level of resource use and environmental efficiency and maximise food security as well as livelihood security.
The purpose of this report is to review the major effects of climate change on the agricultural sector; to examine the causes of vulnerability; and to suggest a range of potential options and investment opportunities for supporting adaptation efforts and, more generally, for building adaptive capacity. This report primarily focuses on appropriate strategies for adapting to climate change impacts that are projected to occur over the next one to two decades, although several issues covered in this report are important for long-term adaptation needs as well.
The paper is one of a series of research papers that are designed to timely disseminate research and policy analytical outputs generated by the USAID funded Feed the Future Innovation Lab for Food Security Policy (FSP) and its Associate Awards. The FSP project is managed by the Food Security Group of the Department of Agricultural, Food, and Resource Economics at Michigan State University (MSU), and implemented in partnership with the International Food Policy Research Institute (IFPRI) and the University of Pretoria (UP).
The purposes of this course are to review the major reforms being considered internationally that aim to change the policy and institutional structure and operations of public sector agricultural extension systems, and to examine the advantages and disadvantages of each of these reforms as illustrated by the selected case studies. Aside from the introductory chapter, the course is organized into nine modules, which are conceived as part of a larger framework.
This publication contains twelve modules which cover a selection of major reform measures in agricultural extension being promulgated and implemented internationally, such as linking farmers to markets, making advisory services more demand-driven, promoting pluralistic advisory systems, and enhancing the role of advisory services within agricultural innovation systems.
