Agroecology is defined as the application of ecological principles and concepts to the design and management of sustainable agricultural agroecosystems (Altieri 2005). Agroecosystem forms the basic unit on which agroecological principles are applied.


The population of the world has increased in recent years and is projected to reach between 9.6 billion in 2050 and 12.3 billion by 2100 (Gerland et al. 2014). The population of the world is expected to continue increasing for the rest of the century, with at least a 3.5-fold increase in the population of Africa. The population of Asia (mostly South Asia) and Africa (mostly sub-Saharan Africa) are expected to record a great share of the projected increase in population (Lichtfouse et al. 2009365体育网站). The increase in population would definitely be associated with an increase in demand for food, energy, and other natural resources. Food security would therefore be mostly threatened in the regions where the...
