Definition of the Subject

Agroecology provides guidelines to develop diversified agroecosystems that take advantage of the effects of the integration of plant and animal biodiversity . From a management perspective, the agroecological objective is to provide balanced environments, sustained yields, biologically mediated soil fertility, and natural pest regulation through the design of diversified agroecosystems and the use of low-input technologies.


Constraints to agricultural production may be classified into four basic categories: abiotic, biotic, socioeconomic, and those related to crop management. The origin and importance of each constraint, their associated losses, and opportunities to alleviate them will vary for the crop, the input and management levels employed, and the environmental and socioeconomic characteristics of the broader farming system in which the crop is grown. Agronomists and plant protectionists usually address production constraints by focusing...
