This paper treats the description of all the procedures carried out in order to produce a map of vulnerability and susceptibility to cave-ins, calculated and evaluated by the multicriteria method (AHP) and by using the GIS tool in the old Medina of Beni Mellal, which is recognized from time to time by cave-ins. The objective of this study is to develop a new method for analyzing the vulnerability of cavities to collapse, which presents a real risk in the urban area of the old cities. The methodology, applied to the old city of Beni-Mellal, consists in identifying and quantifying the stakes linked to the collapse of a cavity using a geographic information system. The weight of each parameter and factor exposed in the vulnerability was estimated using the hierarchical multicriteria method (AHP). The result is presented in the form of a spatialized and synthetic vulnerability map. The detection, mapping and assessment of areas vulnerable to the collapse of these cavities, particularly for large areas of the city, offers the possibility of reducing damage by intervening upstream and introducing preventive and corrective measures against any risk of collapse in the areas deemed vulnerable by our study. The maps show three zones with different degrees of vulnerability. The low and medium vulnerability zones occupy respectively 30 and 20% of the total area of the old city, while the high and very high vulnerability zones occupy respectively 16% and 4%.","PeriodicalId":202277,"journal":{"name":"Journal of Environmental and Agricultural Studies","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126652927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of water for oranges has a significant role in the final production of the product. In Indonesia, there are three types of rain patterns with variations in the growing season related to water availability: the rainy season between October and March and the dry season between April and September. Climate extremes such as drought (El-Niño) and wetness (La-Niña) fluctuate dynamically, impact shifts at the beginning and end of the growing season, and hurt citrus crop productivity. Therefore, an analysis of rice planting time in tidal swampland in Barito Kuala under extreme climatic events was carried out. The research was conducted in September – December 2020 with the survey method. The data was dug in-depth on the research respondents: citrus farmers, fruit traders, and related agencies. The number of samples was 90 people (45 male farmers and 45 female farmers). Two different villages were surveyed in each sub-district according to the type of tidal land, namely Marabahan sub-district (SP1 village and SP2 village), type A, Mandastana (Karang Indah village and Karang Bunga village) type B, and Cerbon sub-district. (Village of Simpang Nungki and Sungai Kambat) Type C. Planting time in tidal land begins after the amount of rainwater is sufficient to dissolve the iron content in the water. The probability of an El-Niño occurrence with an intensity of 1, 2, 3, and 4 years has the highest frequency of occurrence—respectively 3, 3, 5, and 3 times with probability around 16.7% to 27.8%. Meanwhile, La-Nia with an intensity of once a year with the highest frequency eight times with a 40.0% chance. La-Nia events coexist with El-Nio 15 times, and generally, El-Nio precedes La-Nia by about 44%. The cropping pattern in tidal swampland shows high resistance to climate change. Namely, the planting time has not changed much for decades under different climatic conditions.","PeriodicalId":202277,"journal":{"name":"Journal of Environmental and Agricultural Studies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116562087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The assessment of Sediment Yield (SY) and Suspended Sediment Yield (SSY) remains a challenging global issue, especially in Morocco, characterized by a great diversity of morphological, climatic, and vegetation cover. The main objective of this paper was to perform advanced statistics and artificial neural networks (ANN) in order to understand the spatial distribution of sediment yield and the factors most controlling it, including factors of the RUSLE model (Revised Universal Soil Loss Equation). In order to produce a model able to assess SY, we collected and analyzed extensive data of most variables that can be affecting SY using 42 catchments of the biggest and important dams of Morocco. Statistical analysis of the studied watersheds shows that SY is mainly related to the watershed area and the length of the drainage network.  On the other hand, the SSY is higher in watersheds where gully erosion is abundant and lower in areas with no soil horizon. The SSY is mainly related to the altitude, aridity index, sand fraction, and drainage network length. In front of the complexity of preserving this phenomenon, the ANN was applied and gave very good satisfactory results in predicting the SSY (NSE=0.93, R2=0.93).","PeriodicalId":202277,"journal":{"name":"Journal of Environmental and Agricultural Studies","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126430427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liquid smoke is used as an alternative food preservative and flavor enhancer that it can use in the food processing industry to minimize the use of harmful preservatives such as formalin. But it also can be used as a biopesticide in agriculture so that it becomes an alternative to chemical pesticides in controlling pests. It was researched at the Research Laboratory of the Chemical Engineering Department FTI UMI Makassar in July 2020 and the Agrotechnology Laboratory of the Petra Baliem Wamena Agricultural Science College in April 2021. The research activity began by making grade 3 liquid smoke because liquid smoke can be used as a biopesticide at this level. Then proceed with the analysis of the chemical and physical content of liquid smoke. The research method used was an experimental method with six replications on the amount of red fruit seed waste 500 g, 1000 g, and 1500 g. The pyrolysis process was carried out at temperatures ranging from 300-400ºC for 180 minutes. The results of the observations from the tests carried out showed that the liquid smoke of red fruit seed waste produced was more in the weight or quantity of red fruit seed waste 1000 g was BM2 treatment which had a pH value of 3.35, the acid content of 14.20%, total phenol content of 4.91%, quite brown.

The impacts and threats from a changing climate have the potential to significantly impact all sectors of the global economy and will largely be multifaceted, multidimensional, and multi-sectoral. These adverse impacts will to a greater extent, be manifested at the local and community level where the adaptability capacity is weak and resources are scarce. In the last two decades, there has been growing support and evidence that suggests that local people and communities in partnership with their local governments and NGOs are undertaking community ecological based adaptation (CEBA) practices at both the local and community level which are enhancing their adaptability and resilience capacities to a changing climate. CEBA mechanisms are initiatives and practices that local and rural communities across the developing world are sometimes adopting in partnership with their local government and non-governmental organizations to adapt to a changing climate. However, over the years, these initiatives, experiments, and activities have been poorly actualized, communicated, and there is uncertainty on whether these practices and mechanisms are enhancing the adaptability and resilience capacities of the many poor people in these communities. It is from this background that this paper seeks to assess and analyze present and future climate change impacts on agriculture in Central Zambia and further seeks to appraise the effectiveness of CEBA mechanisms being adopted and utilized in this region. Using community assessment and rural appraisal tools this research paper found that indeed some CEBA practices are innovative and effective and are enhancing the adaptability and resilience of the local people in agriculture in this region. The paper recommends that the advancement, funding, and integration of innovative and effective CEBA practices with scientific knowledge and the ultimate replication and incorporation of these practices into developmental and climate change policies can be one of the most beneficial and effective ways for a sustainable, adaptive, and resilient agriculture sector in the face of a changing and unpredictable climate.","PeriodicalId":202277,"journal":{"name":"Journal of Environmental and Agricultural Studies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128409390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the effect of Bonny Light crude oil on cowpea (Vigna unguiculata L. Walp.) was investigated with a view to assessing its toxicity to plant growth and performance. Pristine soil samples were collected in different pots and contaminated with crude oil to achieve 0.0%, 2.5%, 5.0%, 7.5% and 10.0% v/w contamination levels. Viable seeds of cowpea were planted and monitored for the emergence and subsequent growth for a period of 12 weeks. Results showed that the crude oil extended the period of seed germination and delayed the emergence of sprouts by 2 days at a rate of 96.7%, 80.0%, 50.0%, 96.7%, and 73.3% emergence respectively. The plants’ shoots, roots, and leaves lengths were longer in control than in the contaminated soil. Phytotoxicity study showed that shoots, roots and leaves lengths of the plants were significantly reduced by ≥ 50% of the control. The relative plants' weights, chlorophyll, and the number of leaves were worst affected especially in plants grown in higher crude oil concentrations where fewer or absence of leaves was observed at the end of the experiments. No yield parameter was observed in all plants grown in contaminated soil as opposed to the control where flowers, fruits, and seeds were produced. The findings illustrated that the growth rate of V. unguiculata was severely affected due to hydrocarbon contamination in a concentration-dependent manner. It further demonstrated the imminent danger to food security especially in frontier basins with impending oil exploration activities. Therefore, there is a need to identify and integrate effective measures that minimize or prevent oil spillage in the course of oil exploration activities with a view to avoiding the repeat of persistent pollution problems disturbing host communities.","PeriodicalId":202277,"journal":{"name":"Journal of Environmental and Agricultural Studies","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122750593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
