Hydrochemistry of Groundwater in the Rice Cultivation Area of Maga: Analysis of the Mineralization Process

Journal of Geoscience and Environment Protection 2024年第9期12卷 370-387页

作者： Emmanuel Aguiza Abaï Hugues Pahimi Prosper Samba Koukouare guillaume Ewodo Mboudou Auguste Ombolo Department of Industrial Security Quality and Environment National Advanced School of Mines and Petroleum Industries University of Maroua Kaele Cameroon School of Chemical Engineering and Mineral Industries University of Ngaoundere Ngaoundere Cameroon Department of Hydrocarbons Exploitation Mao National Higher Petroleum Institute NDjamena Chad Department of Hydraulics and Water Management National Advanced School of Engineering of Maroua University of Maroua Maroua Cameroon Department of Rural Engineering Higher Institute of Agriculture Forestry Water and Environment University of Ebolowa Ebolowa Cameroon

The use of groundwater for drinking water supply to the population is increasingly practiced in the rice cultivation area of Maga. However, there is a lack of knowledge about the hydrochemical characteristics of this water due to a lack of quality control. This study aims to contribute to the understanding of mineralization processes in order to establish the hydrochemical profile of the water in the area. The methodological approach consisted of collecting fifteen water samples from wells and boreholes during six campaigns for physicochemical analysis, and studying them through methods of interpreting hydrochemical data. The analysis results show that these waters are moderately mineralized. The water facies are mainly of the bicarbonate sodium and potassium type, as well as the bicarbonate calcium and magnesium type. Calculation of saturation indices demonstrates that evaporite minerals show lower degrees of saturation than carbonate minerals, with gypsum, anhydrite, and halite being in a highly undersaturated state. The mineralization of groundwater originates from the dissolution of surrounding rocks on the one hand, and anthropogenic activities involving exchanges between alkalis (Na+ and K+) in the aquifer and alkaline earth (Ca2+ and Mg2+), resulting in the fixation of alkaline earth and the dissolution of alkalis.

Perception of the Mechanization of Rice Cultivation and Its Effects on the Soil in the Senegal River Valley

引用

Agricultural Sciences 2024年第6期15卷 704-718页

In Senegal, particularly in the Senegal River valley, agricultural mechanization remains limited, mainly due to a lack of agricultural equipment, a lack of expertise in agricultural machinery and an apprehension of the consequences on soil quality. To better understand agricultural mechanization of rice cultivation, this survey study has been carried out in the Senegal river valley. Precisely, this work aimed to characterize farm machinery and its effects on soil and rice cultivation. A questionnaire was administered to 304 out of 1270 farmers, spread over 8 rice-growing areas, 4 of which are located in the Podor department, three in Dagana and one in Saint-Louis. The results showed that 99.3% of farmers used motorized equipment, with 95.7% using tractor and 3.6% a power tiller. Offset tillage, which is a shallow cultivation practice carried out to break up hard soil without turning it over, was most widespread among growers (95.4%). 78.3% of the valley’s farmers felt that the machinery used to carry out tillage operations was inefficient. According to the farmers, the main constraints on the use of agricultural machinery in the valley were: the upkeep and maintenance of equipment (57%), the lack of expertise in mechanization (31%), and issues adapting machinery to local conditions (12%). Those constraints have contributed to a drop in yields in recent years, the spread of weeds on cultivated plots and the gradual degradation of the soil in the area according to 78% of farmers.

本文以景颇语中声调交替的致使动词为研究对象,试图从历史语言学的角度对该现象提出构拟和解释。本文论证了景颇语致使范畴的声调交替源自致使前缀脱落这一分析方法存在的问题,并参照基兰提支语言的相关现象提出了另外一种更可行的分析,即景颇语致使范畴的声调交替不是因致使前缀脱落造成的变化,而是施用态-t后缀脱落留下的痕迹。

Introduction: Human rabies is a major public health problem in many African countries, including Côte d’Ivoire. The present work aims at describing the eco-epidemiological characteristics of human rabies cases recorded in Côte d’Ivoire. Methods: This was a retrospective and prospective cross-sectional descriptive study based on epidemiological surveillance data that ran from september 2014 to december 2017. The clinical data were extracted from the database of the human rabies epidemiological surveillance management service of the National Institute of Public Hygiene’s rabies centre. These data cover the period from 1 January 2012 to 31 December 2017. Results: Human rabies is endemic in Côte d’Ivoire, with most people exposed in the south and especially in the west of the country. There was no association between any of the climatological parameters (temperature, humidity, rainfall) and the occurrence of human rabies during the months of exposure to rabies infection. Conclusion: Ultimately, effective prevention and control of human rabies requires a thorough understanding of the links between climatological parameters and rabies. Health authorities must take ownership of these results if we are to achieve our goal of eliminating rabies by 2030.

Evaluation of the Use of Long-Lasting Impregnated Mosquito Nets (LLINs) in the Health District of Dimbokro (Center of Côte d’Ivoire)

The Dimbokro health district has one of the highest incidences of malaria in Côte d’Ivoire, despite numerous campaigns to distribute Long-Acting Impregnated Mosquito Nets (LLINs). Given this observation, what are the population’s attitudes towards LLINs that could explain the high endemicity of malaria in Dimbokro? The aim of this study is to assess the knowledge, attitudes and practices of people in the health area of Nofou, one of the villages in the Dimbokro health district where malaria is most prevalent, with a view to strengthening malaria control strategies. A collection of historical health data (malaria cases and LLIN usage rates) and a cross-sectional questionnaire survey was carried out from July 20 to August 03, 2022 in 400 households selected by systematic random sampling. Data were entered using Epi Info 7 and multivariate statistical analyses were performed using IBM SPSS 22 software. In the Dimbokro health district, the rate of LLIN use was negatively correlated (r = -0.771) with malaria incidence over the six years of historical data collection. Households had an average of 53% good knowledge, 68.6% good practices and 28.4% good attitudes towards LLINs. The study also revealed that the main factors explaining LLIN use in the Nofou health area are mosquito bite (ORa = 5.29 (1.12 - 25.04)), age of household members (ORa = 1.07 (1.01 - 1.14)) and marital status (ORa = 8.45 (1.70 - 45.02)). Awareness-raising on the use of LLINs should be intensified in the Dimbokro health district. Other control strategies, such as vector control and environmental sanitation, should be considered to combat malaria.
