Agroecology

Summary

Agroecology (IPA: /ˌæ.ɡroʊ.i.ˈkɑː.lə.dʒi/) is an academic discipline that studies ecological processes applied to agricultural production systems. Bringing ecological principles to bear can suggest new management approaches in agroecosystems. The term can refer to a science, a movement, or an agricultural practice. Agroecologists study a variety of agroecosystems. The field of agroecology is not associated with any one particular method of farming, whether it be organic, regenerative, integrated, or industrial, intensive or extensive, although some use the name specifically for alternative agriculture. Agroecology is defined by the OECD as "the study of the relation of agricultural crops and environment." Dalgaard et al. refer to agroecology as the study of the interactions between plants, animals, humans and the environment within agricultural systems. Francis et al. also use the definition in the same way, but thought it should be restricted to growing food. Agroecology is a holistic approach that seeks to reconcile agriculture and local communities with natural processes for the common benefit of nature and livelihoods. Agroecology is inherently multidisciplinary, including sciences such as agronomy, ecology, environmental science, sociology, economics, history and others. Agroecology uses different sciences to understand elements of ecosystems such as soil properties and plant-insect interactions, as well as using social sciences to understand the effects of farming practices on rural communities, economic constraints to developing new production methods, or cultural factors determining farming practices. The system properties of agroecosystems studied may include: productivity, stability, sustainability and equitability. Agroecology is not limited to any one scale; it can range from an individual gene to an entire population, or from a single field in a given farm to global systems.
