“…In addition, in the process of using natural resources to develop the economy, due to the problems of overexploitation and irrational utilization, scientific methods and means are not paid attention in production, which will also lead to the ecological environment of food cultivation becoming increasingly fragile [36,37]. Farmers have applied chemical inputs such as fertilizers, pesticides and herbicides in large quantities and in an uncontrolled manner for a long time, causing large areas of cultivated land to suffer erosion and pollution to varying degrees [6,38]. At present, the fertilizer application amount is as high as 400 kg/ha, far exceeding the safety limit of 225 kg/ha in developed countries [39].…”

It is of great significance to systematically analyze the characteristics of the regional grain supply and demand balance, reveal the influence mechanism of crop sustainable development, and put forward effective countermeasures to achieve the goal of food security. This paper aims at addressing the unique geographical characteristics of Northwest China and the current lack of research on its food security. This paper systematically analyzes the temporal and spatial variation characteristics of the regional grain production, consumption and food security level. The main factors affecting regional food security are examined, and we put forward effective suggestions to promote regional sustainable production. The results show that the average annual growth rate of grain production in Northwest China from 2000 to 2021 was 3.4%, and the years of increased grain production accounted for 77.3%. The main reason for the increase in grain production was the increase in yield per unit area (average annual growth of 2.8%), of which the rice yield was the largest, up to 7.3 t/ha. Maize and wheat accounted for 60.7% and 23.4% of the total grain production in the region, respectively. From the perspective of the regional structure, Inner Mongolia contributed the most to the grain production in the region, accounting for 33.5% of the total output. Xinjiang, Shanxi, Shaanxi, Gansu, Ningxia and Qinghai contributed 17.1%, 15.4%, 15.2%, 13.0%, 4.5% and 1.3%, respectively, to grain production. From the perspective of the dietary structure, the grain consumption pattern in Northwest China has gradually changed from raw grains to animal products, which has undoubtedly increased the regional demand for grain. At present, since the increase in output is greater than the demand for food, the food self-sufficiency rate in the region has increased from 0.81 to 1.28. Since the grain yield per unit area in Xinjiang and Ningxia has a relative advantage over other provinces, to achieve regional food security for a long time, moderately increasing the grain planting area in these two provinces will help to promote regional food security. In addition, as the grains produced in the region are mainly wheat and corn, the yield level of wheat and corn in Xinjiang and Qinghai has a comparative advantage within Northwest China. Therefore, moderately increasing the planting area of wheat and corn in Xinjiang and Qinghai is of great significance in ensuring regional food security. The research results can provide theoretical support for the realization of regional food security and provide a reference for other regions in the world, to better serve global food security.

“…It is valuable due to its nutritional qualities, stability, and good behavior in heat. In Morocco, the main groundnut production basin, particularly in irrigated cultivation, is located in the south-east of the Tangier region, particularly in the sandy coastal zone bordering the Atlantic extending between Larache and Kenitra, on approximately 25,000 hectares ( Abbou et al, 2022 ) and its production is 38,000 tons according to statistics from the International Production Assessment Division of USDA’S ( USDA-IPAD, 2022 ). However, this production is subjected to various types of constraints: biotic stresses, such as abundance and diversity of weeds and fungal and microbial infection, and abiotic stresses, such as drought, salinity, and low soil fertility, which affect negatively seedling, vegetative and reproductive growth, seed quality, and yield ( Nithila et al, 2013 ; Verma et al, 2013 ; Valenzuela-Ruiz et al, 2018 ).…”

In order to increase genetic variability for the improvement of groundnut, two varieties, namely Kp29 and Fleur11, were treated with six different gamma irradiation doses. A significant effect of mutagenesis was distinctly observed in the stem lengths, roots, and survival percentage in both varieties. The radio-sensitivity test showed a mean lethal dose of 436.51Gy for Kp29 and 501.18 Gy for Fleur11. Furthermore, this study revealed putative mutants with variable agro-morphological traits. Seven chlorophyll mutants and various seed shape and color mutants were obtained. This study demonstrates the potency of gamma irradiation to induce high genetic variability that led to the emergence of certain mutations of economic importance.

Loukkos perimeter is among the most important irrigated agricultural areas in Morocco. It covers horticulture and market garden production, including potato. This crop is characterized by the intensive use of pesticides that could lead to health and ecological risks, via the food chain and contamination of natural resources, including groundwater. This study aims to assess the use of pesticides in potato cultivation and their impacts on the environment and human health. Here, pesticide use was characterized by the number of treatments (NT), quantity of active substances indicator (QASI) and the treatment frequency indicator (TFI), through eld surveys carried out on 50 Loukkos potato producers. The results showed that farmers use heavy pesticide treatments, mainly against late blight. We determined NT = 19 treatments, total TFI = 28.10 and QASI = 14.86 kg/ha. These values re ect a massive use of pesticides on this crop, which could therefore constitute a challenge and a major constraint for the development of sustainable agriculture in this zone, due to their negative environmental and health effects. It is, therefore, necessary to react quickly to make changes in phytosanitary practices with the aim to monitoring pesticide use via the agro-environmental indicators to reduce health and environmental impact of intensive pesticide use.
