Poverty is prevalent in the small-farm sector of many developing countries. A large literature suggests that contract farming —a preharvest agreement between farmers and buyers— can facilitate smallholder market participation, improve household welfare, and promote rural development. These findings have influenced the development policy debate, but the external validity of the extant evidence is limited. Available studies typically focus on a single contract scheme or on a small geographical area in one country.
Precision farming enables agricultural management decisions to be tailored spatially and temporally. Site-specific sensing, sampling, and managing allow farmers to treat a field as a heterogeneous entity. Through targeted use of in- puts, precision farming reduces waste, thereby cutting both private variable costs and the environmental costs such as those of agrichemical residuals. At present, large farms in developed countries are the main adopters of pre- cision farming.
In this review, we examine the debate surrounding the role for organic agriculture in future food production systems. Typically represented as a binary organic–conventional question, this debate perpetuates an either/or mentality. We question this framing and examine the pitfalls of organic–conventional cropping systems comparisons. The review assesses current knowledge about how these cropping systems compare across a range of metrics related to four sustainability goals: productivity, environmental health, economic viability, and quality of life.
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%).
International agricultural research is often motivated by the potential benefits it could bring to smallholder farmers in developing countries. A recent experimental literature has emerged on why innovations resulting from such research, which often focuses on yield enhancement, fail to be adopted due to either external or internal constraints. This article reviews this literature, focusing on the traits of the different technologies and their complexity and distinguishing between yield-enhancing, variance-reducing, and water- or labor-reducing technologies.
Food systems contribute 19%–29% of global anthropogenic greenhouse gas (GHG) emissions, releasing 9,800–16,900 megatonnes of carbon dioxide equivalent (MtCO2e) in 2008. Agricultural production, including indirect emissions associated with land-cover change, contributes 80%–86% of total food system emissions, with significant regional variation. The impacts of global climate change on food systems are expected to be widespread, complex, geographically and temporally variable, and profoundly influenced by socioeconomic conditions.
This research refers to the application of a innovation framework to sustainable livestock development research projects in Africa and Asia. The focus of these projects ranged from pastoral systems to poverty and ecosystems services mapping to market access by the poor to fodder and natural resource management to livestock parasite drug resistance.
In this book, the authors assessed the role of biotechnology innovation for sustainable development in emerging and developing economies. This book compiles studies that each illustrate the potential, demonstrated value and challenges of biotechnology applications for sustainable agricultural innovation and/or industrial development in a national, regional and international context.
En los últimos 25 años se han producido cambios significativos en la vida rural de América Latina, en sus dimensiones política, económica, social, laboral, demográfica, cultural y ambiental, a partir de lo que se denominó los Programas de Ajuste Estructural y de las decisiones políticas y económicas que tomó cada país en particular. Uno de los elementos centrales y determinantes de las reformas en los Sistemas de Extensión y Transferencia de Tecnología Agraria (SETTA) ocurrió a partir de fines de la década de los setentas y principios de la década de los ochentas.
Durante la IX Reunión del Grupo Técnico de Investigación, Tecnología, Transferencia e Innovación del CAC el 28 de noviembre de los corrientes en la ciudad de Panamá. Para el PDRR la agricultura familiar necesita de nuevos y fortalecidos sistemas locales de innovación que sean especializados para su actividad, esto requiere de una agenda planificada desde los territorios con el fin de atender las demandas de los productores familiares.
