This coastal aquifer is formed by subsidence and sedimentation. (2016) in India and Ait El Mekki & Laftouhi (2016) in Morocco. (2014) in Nigeria, Abdalla (2012) in Egypt, Mohebzadeh et al. During the last years, several studies have been carried out to assess groundwater potential mapping in different regions of the world with satisfactory results as shown by field surveys ( Magesh et al. For this study, we used a combination between MCDA approach and GIS technique to delineate groundwater potential zones. Nowadays, computer technology (programming or software) is used in hydrogeology studies.

This time gaining method allows establishment of thematic maps such as geology, hydrology, geomorphology, lineaments and slope ( Shaban et al. Potential groundwater recharge mapping is useful to assist water resource managers to better plan water exploitation and management ( Saidi et al. The obtained results, in this work, describe the groundwater recharge potential areas and supply information for a suitable mapping and the management of aquifer resources in the study area. The best groundwater potential zones are situated in the piedmont of the Blidean Atlas (the south of the study area), precisely, upstream near to wadis (wadi El Harrach, wadi Djemaa, wadi Mazafran) and the western aquifer limit, where the hydrogeological units are formed by the alluvium formation which is characterized by high hydraulic conductivity, high water flow, low slope, low drainage, low quantity transported sediments and good water quality. Three potential groundwater recharge classes were defined corresponding, respectively, to low (26%), moderate (47%) and high (27%). The analysis was based on the use of a geographical information system (GIS) and remote sensing to establish eight thematic maps, weighted, categorized and inserted, that allowed us to establish the potential zonesвЂ™ map for groundwater recharge. The predicted potential distribution of Arabica coffee based on MaењЋnt model and AHP-GIS model could provide reference for the implementation of long-term planning and development programs so as to alleviate the effects of climate change on the distribution of Arabica coffee.This work aims to identify the potential groundwater recharge zones in the Mitidja plain (north Algeria) using the multi-criteria approach. At the same time, the distribution of the most suitable area migrated northward generally to higher altitude and higher latitude, and the migration distance was 27.44вЂ“92.22В km. Under the future climate scenario model, MaењЋnt and AHP-GIS predicted that the area of the most suitable area would increase by 2.62В Г—В 10 4вЂ“4.42В Г—В 10 4В km 2 and 3.53В Г—В 10 4вЂ“5.44В Г—В 10 4В km 2 respectively from 2021 to 2100, which were mainly concentrated in west, southwest and southeast Yunnan. The most and moderately suitable areas were mainly concentrated in west, southeast, south and southwest Yunnan. MaењЋnt predicted that the most and moderately suitable area accounted for 16.26% and 22.59%, and AHP-GIS predicted that they accounted for 13.35% and 41.32% of the total area respectively. The model accuracies of MaењЋnt and AHP-GIS were 0.925 and 0.833 respectively, indicating that the two methods were reliable in the ecological suitability evaluation of Arabica coffee. Results showed that the ecological suitability of Arabica coffee plantation was mainly subjected to the climate factors, among which the maximum temperature in the warmest month, minimum temperature in the coldest month and the annual precipitation were particularly important, followed by terrain and soil factors.

Based on climate, terrain and soil data, MaењЋnt model and AHP-GIS technology were used to evaluate and analyze the increase and decrease range of Arabica coffee ecological suitability planting areas and most suitable areas in different periods, determine the most significant environmental factors affecting ecological suitability, and determine the distribution transformation under climate change scenario (SSPs370). However, there still lack of studies regarding the potential distribution of suitable planting regions and the important environmental factors that affect the growth and development of Arabica coffee. Coffee, as one of three major beverages all over the world, is featured by many functions mainly including refreshment, diuresis, invigorating stomach and stimulating appetite.
