Flood is a recurrent natural disaster that has caused enormous human and material damage in many places and continues to hit local committees at an alarming rate. The need to setup permanent committees to prevent and manage flood disasters by local communities is therefore indispensable. In rural areas, the creation of such a structure is always a welcome relief to flood victims but it is often marred by numerous management problems. This study aimed to analyze the community-based approach in the prevention and management of flood disasters in Babessi Subdivision (North West Cameroon), to identify the causes of flood disasters and the preventive strategies used by this local community. A total number of 300 questionnaires as well as structured interviews were used to collect data in the field and the data were analyzed by simple descriptive statistics. The main results revealed that the main cause of flood disasters is heavy and consistent rainfall. Also, poor refuse disposal and drainage system management contribute to floods. The identification of areas likely to be affected by floods and preventing the riparian population from constructing houses along these areas especially beside the main rivers are the flood preventive measures adopted by the local flood management committee. The flood victims are reluctant to relocate to the settlement site earmarked by the Government, meanwhile, the local flood committee do not have the legal tools to forcefully relocate them. The population of Babessi needs to be sensitized on the impending dangers of flood hazard and be encouraged to participate in implementing the adopted strategies to prevent and manage subsequent flood disasters.

Assessment of Groundwater Quality for Domestic and Irrigation Purposes in Northern Bamenda (Cameroon)

Journal of Water Resource and Protection 2021年第1期13卷 1-19页

Safe and reliable drinking water availability constitutes a nightmare in many towns of developing countries and is usually appreciated from its physical appearance without prior knowledge of its chemical and biological properties. This study investigates the suitability of groundwater for domestic and irrigational purposes through physico-chemical and bacteriological analyses in the Northern part of Bamenda Town (Cameroon). Thus, 20 groundwater samples were collected from hand-dug wells and spring sources in September 2018 (rainy season) and February 2019 (dry season) and physico-chemical and bacteriological characteristics were determined. The results revealed that pH ranged from 5.5 to 6.6, thus enabling the classification of the water as slightly acidic. Electrical conductivity varied between 0.01 - 0.06 μS/cm. The relative abundance of ions was such that Ca2+ > K+ > Mg2+ > Na+ for cations and HCO-3 > Cl- > NO-3 > SO-4 for anions. The water types were Ca-Mg-NO3 in both dry and rainy seasons. The results revealed that the mechanisms controlling groundwater chemistry are rock weathering and atmospheric precipitation. Indicator bacteria such as E. coli, Shigella, Enterobacteria, Vibrio, Streptococcus and Staphylococcus were detected in the studied groundwater samples, thus the water sources may pose a threat to public health.

Literature Review of the Prevalence of Hypertension at Gulu University, Gulu City, Acholi Subregion, Northern Uganda

引用

World Journal of Cardiovascular Diseases 2024年第9期14卷 588-602页

作者： Lamwaka alice Veronica Mboowa John Bosco Department of Pharmacy Faculty of Medicine Gulu University Gulu City Uganda

Hypertension is a big problem worldwide. The purpose of this study is to examine the prevalence, knowledge, attitude, and practice about hypertension at Gulu University, Gulu city, Gulu district, Acholi subregion, Northern Uganda. A literature search on hypertension was done. It showed that, in Uganda, a representative number of 17,777 adult patients’ data were analyzed from January 2014 to February 2024. The epidemiological data on awareness of hypertension was found to be at 8%. Of this, 18.3% of the people with hypertension had it under control. The results of the findings were promising. Hypertension is an important public health challenge in Uganda particularly in Northern Uganda where Gulu University falls. In comparison with the two regions of Central Uganda and Northern Uganda, there was a significant number of populations that were not aware of their condition. Those diagnosed were on treatment but the treatment was not adhered to due to stock outs of medicines. Therefore, Measures are required to prevent hypertension, improve awareness, treatment and control within the community, especially at Gulu University where research has never been done.

Assessment of Groundwater Stability Using Corrosion and Scaling Tendency Indices on Selected Springs in the Manga Region in Nyamira County, Kenya

引用

Open Journal of Microphysics 2024年第3期14卷 79-88页

作者： Calford Odhiambo Otieno alice Makonjo Wekesa Physics Department Kisii University Kisii Kenya

We present the result of groundwater stability assessment on three major springs in the Manga region in Nyamira County found in Kenya in 2018. These springs are Kiangoso (SP1), Kerongo (SP2) and Tetema (SP3). The corrosion and scaling tendency indices were obtained using the Langelier saturation index (LSI), Ryznar stability index (RSI), and Puckorius scaling index (PSI). The LSI values obtained for SP1, SP2, and SP3 are −3.93, −4.71, and −4.17, respectively, while using RSI, the values obtained for SP1, SP2, and SP3 are 14.15, 14.53, and 13.74, respectively. Using PSI, the values of SP1, SP2, and SP3 are 5.58, 5.45, and 5.58, respectively. From the interpretation of the indices, the groundwater from the three springs in the Manga region using LSI and RSI showed intolerable corrosion;hence, it is unlikely to scale as obtained from PSI.
