The issue of promoting peri-urban agriculture seems to be an important one in response tothe various current concerns about the future of cities in the face of climate change. At firstsight, these peri-urban agricultural areas, which in the past provided shelter for cities, arenow threatened by urban sprawl and are increasingly losing their function of protectingurban areas from climatic hazards. This question is a priority when considering the future ofagriculture in today's urban sprawl. We are therefore raising a number of concerns linked tomultiple issues: the trampling of green space, agricultural environmental sustainability,territorial impacts and the difficulty of managing rural and urban populations.Around these questions, this research is structured to provide theoretical and practicalknowledge that will enable us to place peri-urban agriculture at the heart of urban concerns,in a perspective of reaction to climate change. The interest of this work is reinforced in thecase of peri-urban areas surrounding the capital of Algiers, such as the commune of DelyBrahim: a concrete example of a territory concerned by the subject. On the one hand, thisperiphery boasts important agricultural production zones in close geographical proximity tothe capital Algiers, and on the other, it plays a fundamental economic, environmental andlandscape role in relation to its region. Between its dense urban residential areas, itsagricultural areas threatened by urban sprawl and its natural areas rich in resources, thisterritory is today confronted with numerous environmental vulnerabilities. The aim istherefore to examine the issue of preserving the agricultural sector and its role in mitigatingclimate change.
