“…In Algeria, geographical research has long been centered on the city due to the phenomenon of urban sprawl. Only recently has it started addressing and continuing to grapple with the predicament of peri-urban land, leading to conflicts over land ownership [10].…”

This article aims to investigate the complex relationship between a local population and its natural and urban environment. The study area, which was previously dominated by cereal cultivation, is currently facing profitability challenges due to climate change, water scarcity, rapid urban expansion, and the overexploitation of aquifers, influenced by changes in agricultural practices, which are disrupting the local ecosystem. This study relies on three interconnected indicators, population growth, climate change effects on agriculture, and the NDVI (Normalized Difference Vegetation Index), and reveals the impact of these factors on agricultural practices. Google Earth Engine was employed to determine the urbanization and greenness indices using scripts. The significant findings of this study demonstrate the remarkable demographic growth of 49.96% during the study period (2000–2020). Furthermore, this growth has led to a new trend towards intensive farming, with a substantial increase in irrigated lands by 44.19% and a multiplication of protected crop lands by 20 times, rising from 19.88 to 405.89 hectares. Additionally, horticultural production surged by 212.4% during the same period. Moreover, groundwater levels shifted from less than 50 m in the northern regions to less than 150 and 300 m in the southern part of the study area. The water potential in the study zone cannot meet the demands of the new agricultural orientation, which tends to deplete local groundwater, potentially causing recurrent shortages of agricultural products. This study underscores the importance of incorporating agricultural production into future urban planning and development programs to maintain a renewed balance between built environments and agriculture in peri-urban areas.

“…Oran, a dynamic Mediterranean city and the second largest Algerian agglomeration, located in the north-west of the country as shown by Figure 1, spread out according to a rapid pace of urban growth by artificialising an average of 110 ha per year [3]. It postponed its urbanization on neighboring agglomerations [4]. In recent years, these have become urban suburbs, encompassed by the dynamics of the agglomeration.…”

In Algeria, the alternative to the absence of these air pollution measurement networks can come from the recent development of electrochemical sensor technologies for air quality monitoring which arouses a certain interest because of their miniaturization, low energy consumption and low cost. We developed a low-cost outdoor carbon monoxide analyzer called APOMOS (Air pollution Monitoring System) based on electrochemical sensor managed by microcontroller. In order to validate the APOMOS system, the recorded measurements are compared with measurements taken by a conventional analyzer. Comparison of the measurements resulting from conventional analyzer and those resulting from the APOMOS system gives a coefficient of determination of 98.39 %.

Résumé -Oran, ville méditerranéenne dynamique et seconde agglomération algérienne, a évolué selon un processus d'urbanisation diffuse. Ses franges rurales périurbaines, aux contours flous, lieux d'importantes transformations, sont actuellement des espaces de production agricole. Une redéfinition de l'agriculture périurbaine s'opère par des initiatives individuelles qui se traduisent par une diversification agricole : développement de cultures à forte plus-value, maraîchères, arboricoles et ornementales. Les entretiens directifs menés auprès des agriculteurs périurbains ont permis d'expliquer les facteurs qui sont à l'origine de ces transformations. Le profit tiré des cultures pratiquées est en lien avec l'accroissement de la demande citadine, l'intensification agricole étant une réponse à la précarisation foncière engendrée par l'urbanisation et par le morcellement excessif des propriétés.Mots clés : agriculture périurbaine / reconfiguration foncière / stratégies d'adaptation / diversification / Algérie Abstract -Peri-urban agriculture in Oran (Algeria): diversification and adaptation strategies. Dynamic Mediterranean and second Algerian city, Oran has faced a diffuse urbanization process. Its rural fringe, just at the outskirts of the city, is today an area where important changes take place in the agriculture production system. A redefinition of peri-urban agriculture is carried out by individual initiatives that result in agricultural diversification: developing high added-value crops, vegetables, and ornamental trees. The structured interviews carried out with the peri-urban farmers allowed identifying the factors that are causing these changes. The profit issued from the crops is in line with the increase in the urban demand; agricultural intensification is a response to the land insecurity created by urbanization and the excessive fragmentation of properties.
