The multiple crises facing humanity at the onset of the Anthropocene are creating a moment in which agroecology acquires greater relevance as an alternative approach for meeting sustainable development goals and providing guidelines for the reconstruction of a post-COVID-19 agricultural system that is capable of minimizing future widespread disrupt...
Article
The COVID-19 crisis has created a moment where existing calls for agroecology acquire new relevance. Agroecology provides a path to reconstruct a post-COVID-19 agriculture, one that is able to avoid widespread disruptions of food supplies in the future by territorializing food production and consumption. There are five main areas in which agroecolo...
Chapter
A key strategy in agroecology is to restore functional biodiversity in agroecosystems at field and landscape levels. Biodiversity performs essential ecological services, and, if correctly assembled in time and space, it can lead to agroecosystems capable of sponsoring their own crop protection. Diversity can be enhanced in crop fields by means of c...

Article
Full-text available
A transition to an agriculture based on agroecological principles would provide rural families with significant socioeconomic and environmental benefits. If agroecology has such great potential to feeding the world, why it is not adopted more widely by farmers? Most research analyzing factors needed for scaling up agroecology focuses on the social...
Book
This new edition builds on the explosion of research on sustainable agriculture since the late 1980s. By separating myth from reality, Miguel Altieri extracts the key principles of sustainable agriculture and expounds on management systems that “really work.” Providing case studies of sustainable rural development in developing countries, he goes b...

Agroforestry often relies on local knowledge, which is gaining recognition in development projects. However, how local knowledge can articulate with external and scientific knowledge is little known. Our study explored the use and integration of local and external knowledge in agroforestry projects in Bolivia. In 42 field visits and 62 interviews w...
Article
Full-text available
Most efforts to improve agricultural production remain focused on practices driven by an intensification agenda and not by an agroecological one. Agroecology transcends the reformist notion of organic agriculture and sustainable intensification proponents who contend that changes can be achieved within the dominant agroindustrial system with minor...
Book
Contemporary agriculture is often criticized for its industrial scale, adverse effects on nutrition, rural employment and the environment, and its disconnectedness from nature and culture. Yet there are many examples of traditional smaller scale systems that have survived the test of time and provide more sustainable solutions while still maintaini...
