The study discusses the impact of open cuts for the extraction of common minerals on soil resources and agricultural lands in Moscow region (MR). For this, the features of soil cover in Moscow region and the distribution of soil types by their use as agricultural resources were analyzed. Further, it was determined which types of soils are subject to varying degrees of open cut load. As a result, a schematic map of the soil cover with open cut load zones was made. It is shown which agricultural lands exposed to open cuts of varying intensity. A conclusion is made about the types of soil cover, which accounts for the greatest and least open cut load, as well as the degree of impact of open cuts on agricultural land resources and the correlation between the degree of open cut load and type of agricultural land use. It is shown that the most fertile soils, which occupy only 2.9% of the MR area, are not affected by the open cut load at all. The greatest open cut load is associated with agricultural lands, represented mainly by various sod-podzolic soils, which occupy 70.5% of the territory of the Moscow region. If economic trends and population growth rates in the Moscow region continue until 2030, we should expect a further increase in the influence of open cut load on agricultural land towards its intensification.

Morocco, like the rest of the world, is experiencing a climate change that threatens a number of wetlands. Marine ecosystems contribute to the regulation of the Earth’s climate, but their degradation releases large quantities of greenhouse gases (GHGs) such as carbon dioxide (CO2) into the atmosphere. This paper aimed to map and model changes in carbon storage and sequestration for coastal habitats using the INVEST model, using the Sidi Moussa-Oualidia lagoon complex as a case study. To achieve this objective, several data were used, namely, land use and land cover maps between 2003 and 2020, as well as data on the amount of carbon stored in the three basins; biomass, sediment carbon (soil) and dead carbon (litter), and the annual rate of carbon accumulation in biomass and sediment. The results obtained in this work allowed us to compare the two former and current carbon stock and net sequestration scenarios and to evaluate the social cost of carbon in the study area. This study can facilitate the development of a coastal rehabilitation strategy to take advantage of the benefits of these wetlands and, at the same time, to conserve the ecosystem services provided by these environments, including the CBCS.

Many studies were carried out in Morocco to show that the dynamics of the market gardening is characterized by frequent use and often uncontrolled use of chemical inputs to the detriment of the preservation of natural resources, the health of consumers and the producers themselves. This reality, calls for appropriate structural actions, based on the levels of sustainability of the sector. The IDEA method (Farm Sustainability Indicators) is one way of giving practical expression to the concept of sustainable farms. Based on 40 sustainability indicators covering the three dimensions of sustainability: agro-ecological, socio- territorial, and economic. Using the IDEA method, we conducted this research with a view to analyze the sustainability of market gardening exploitations in three rural communities: Mnasra, Sidi Mohamed Benmansour, and Benmansour. We conducted questionnaire interviews with 180 producers. The results obtained have generally shown that the market gardening farms in this region have low sustainability scores. The sustainability of farms is lowest on the socio-territorial scale due to the absence of product quality approaches, poor human development, and poor employment conditions and services. On the economic scale, the low viability stands out. The agro-ecological scale shows higher values due to the good organization of space and diversified systems.

In the process of operation, integrated energy systems encounter a series of complex optimization problems such as complex conversion of multiple types of energy, coupling of multiple types of equipment, and uneven distribution of multiple demands. In recent years and in the process of achieving the goal of "double carbon" in China, more and more problems of optimal scheduling of biomass integrated energy systems have become hot topics of research. In this paper, we propose an artificial bee colony algorithmbased operation and scheduling method for a biomass fuel cell (SOFC) cooling, heating, and power triplesupply system with the objective function of maximizing the economic profit of the integrated energy system (including fuel, operation, and maintenance costs), and the constraints of energy conservation, system safety, and operation state. The equipment included are biomass boiler and corresponding steam turbine, biogas digester, SOFC, gas storage tank, etc. The results of the algorithm include the economic benefits of using the artificial bee colony algorithm for the same load scenario. The operational scheduling results show that the artificial bee colony algorithm is able to maximize the profitability of the integrated energy system while reducing carbon emissions.

Soil barrenness is an important type of land degradation, which seriously restricts the food security and sustainable development of agriculture in my country. This paper analyzes the status quo of soil barrenness, its causes and development trends, barrenness treatment measures, and research directions of soil barrenness, in order to serve as a reference for the research and development of soil barrenness.

The world's growing population and the need for food security require rigorous research and development towards climate change-resilient agroecosystems and a major shift toward grain legumes. Faba bean is an important crop in Morocco, providing an essential source of vegetable protein for both humans and livestock with outstanding agronomic, nutritional, and environmental properties. In this review, we present an overview of faba bean crops, including their history, botany, production, importance, and main biotic and abiotic constraints, as well as state-of-theart scientific research on faba bean in Morocco. We also propose insights as future strategies to unlock the potential of faba bean in Moroccan agriculture. Despite its numerous benefits, the cultivation of Vicia faba varieties faces several challenges, including low yield, weeds, pests, disease problems, and climate change. To fully realize the potential of faba bean, there are opportunities for future crop development, including genetic improvement, sustainable intensification, market development, and climate-smart agriculture. Increased investment in research and development, extension services, and infrastructure, as well as constructive agricultural policy strategies, is necessary to increase the number of pulses in various Moroccan cropping systems. By unlocking the potential of faba bean, Morocco can ensure future food and feed security and contribute to the sustainable development of its agricultural sector.

Indonesia is the fourth most populous country in the world, which is significant with energy consumption. Currently, Indonesia is heavily dependent on fossil fuels to its energy needs, but continued reliance on these fuels could lead to depletion. To overcome this problem, biogas is considered as an alternative energy source for cooking and electricity, especially from waste such as cow dung. This research provides an overview of biogas production from small cattle farms in Indonesia, with a focus on cow dung as a valuable resource. It covers factors that increase biogas production, multiple digesters, purification techniques, and integrates Internet of Things (IoT) technologies. Articles for this study were selected using the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method from reputable journals indexed in Scopus and PubMed. Sustainable biogas from cattle farms offers energy generation using abundant cow dung. Optimizing production involves adjusting raw materials, temperature, pH, C/N ratio and HRT. Different types of digesters have unique advantages. Purification techniques such as water scrubbing, PSA, etc. increase methane production. Integrating IoT provides monitoring and optimization. Biogas production has enormous potential for renewable energy, requiring the use and application of efficient techniques, digester types, purification, and IoT integration for a greener future.

Finding suitable installation sites for renewable energy technologies requires careful planning and consideration of multiple factors and not just relying on the location’s energy potential. This research work presents a suitability analysis of solar PV farm installation using GIS and Analytical Hierarchy Process (AHP) in Simara Island, Province of Romblon, Philippines. The study gathered key important details of the island from various sources and then categorized them in terms of climatology, location, environment, meteorology, and disaster susceptibility. Meanwhile, a pairwise comparison was obtained after a panel of experts ranked the above-mentioned parameters. A multi-criteria decision analysis (MCDA) using AHP were then applied to generate new sets of suitability maps, which were combined through weighted overlay analysis using QGIS to produce the necessary solar PV suitability map. The map reveals the spatial distribution of suitable solar PV farm installation sites, including highly suitable, suitable, moderately suitable, marginally suitable, and unsuitable locations. Results show that most of the island is suitable for solar PV farm installation at 42.81%, while 39.73% accounting for highly suitable locations. Moderately suitable and marginally suitable sites account for 8.76% and 1.07%, respectively, and 7.63% is deemed unsuitable. This study successfully identifies suitable locations for solar PV farm installations on Simara Island, demonstrating the effectiveness of the GIS and AHP combined methodology. This approach holds great potential for guiding RE planning and development in similar island regions in the Philippines.
