“…Thus, this study was conducted to develop a hybrid tractor. The objectives of this study were (1) to build a parallel hybrid tractor using components of a hybrid drive system, (2) to establish power management strategies for the hybrid tractor, and (3) to evaluate the performance of the hybrid tractor by comparison with a conventional tractor through field testing [27].…”

The objective of the present work is to evaluate the performance of a low-cost tractor equipped with a parallel hybrid engine, which was simulated using AMESim software. The tractor was evaluated with three different farming implements attached to the tractor, and each implement requires a different type of power. The first simulation was executed without any implements attached. The tractor was able to run for 170 s with the electric motor only, which resulted in fuel savings during this period. The first implement, a moldboard plow, was attached for the second round of evaluation, and the electric motor ran by itself for 150 s, which also led to fuel savings during operation. During the third simulation, the tractor was attached to a Bette Harvest, which has a very high-power demand. The obtained results show that both engines were engaged to provide the required energy. During the final round of evaluation, simulations were run for a straw tub grinder. In this simulation, the electric motor ran alone until the battery was fully discharged. Thereafter, the combustion engine was activated in order to facilitate operations and to charge the battery. The results show that the parallel hybrid architecture employed for the low-cost tractor significantly decreased the CO2 emissions and minimized the consumption of fuel.

“…5. Selon la prospective Agrimonde (Paillard et al, 2010), la production de Kcal/j par ha aurait été multipliée par 2,5 entre 1961 et 2003, la croissance ayant été particulièrement forte en Asie. Dans la zone OCDE, la production alimentaire par actif a été multipliée par 7, mais l'évolution a été beaucoup plus lente pour les autres régions.…”

“…Consequently, the primary challenges for nations revolve around the preservation of peri-urban agricultural land. This is especially pertinent for a country like Algeria, where economic and urban development dynamics are predominantly concentrated in the northern part of the country [9], further exacerbating the phenomenon of littoralization.…”

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.
