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%).
A nutrition-sensitive food system is one that goes beyond staple grain productivity and places emphasis on the consumption of micronutrient-rich nonstaples through a variety of market and nonmarket interventions. A nutrition-sensitive approach not only considers policies related to macrolevel availability and access to nutritious food, but it also focuses on household- and individual-level determinants of improved nutrition. In addition to agriculture, intrahousehold equity, behavior change, food safety, and access to clean water and sanitation are integral components of the food system.
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.
More than 250 million Africans rely on the starchy root crop cassava (Manihot esculenta) as their staple source of calories. A typical cassava-based diet, however, provides less than 30% of the minimum daily requirement for protein and only 10%–20% of that for iron, zinc, and vitamin A. The BioCassava Plus (BC+) program has employed modern biotechnologies intended to improve the health of Africans through the development and delivery of genetically engineered cassava with increased nutrient (zinc, iron, protein, and vitamin A) levels.
En esta sección se retrata como se hace y vive la agroecología en un contexto campesino rural. Desde una comunidad en las Lomas del Escambray (prov. Villa Clara) se intenta transmitir el corazón y la energía de la agroecología en Cuba, a la vez que mostrar el funcionamiento del MACAC, las prácticas cotidianas y las reflexiones de los/as protagonistas.
Cette partie a pour objectif de retracer l’histoire de la création de l’agroécologie et de comprendre les conditions qui lui permettent d’exister dans un contexte paysan rural. Depuis ces mêmes fermes, les protagonistes essayent de transmettre le sentiment et le cœur de l’agroécologie tout en laissant voir le fonctionnement du MACAC, les pratiques quotidiennes et les réflexions de chaque protagoniste.
This section intends to picture how is agroecology done and lived in a rural peasant context. From their own plantations they try to carry over the feeling and heart of agroecology, while showing the operation of PTPAM at the same time, the everyday practices and the thoughts of their main players.
Nowadays, there are a number of projects tackling on challenges around which this study is based. For instance, the ultimate goal of the current project SKIN is to create a permanent stakeholders’ association on short food supply chain (SFSC) that works on the joint economic growth of the agricultural sector through the exchange of local food practices and through coaching sessions stimulating innovation. It creates a European network of best practices in SFSC that addresses the fragmentation of knowledge in the agricultural sector and supports bottom-up innovation initiatives.
The merger of Dow and DuPont, the acquisition of Syngenta by Chem- China, and the acquisition of Monsanto by Bayer have recently reshaped the global seed and biotech industry and caused concern about growing mar- ket concentration. This review documents market concentration in seed and agricultural biotech markets and discusses its causes and impacts. The avail- able evidence suggests that concentration in seed markets varies strongly by crop and by country, while markets for biotech traits are considerably more concentrated.
