Adequate sanitation is one of the most important aspects of community well-being. It reduces the rates of morbidity and severity of various diseases like diarrhea, dysentery, and typhoid among others. A study about toward the attainment of the recommended Humanitarian Sphere Standards on sanitation in Bidibidi refugee camp, Yumbe District, was initiated. A total of 210 households distributed in Bidibidi refugee camp were randomly selected and one adult person interviewed to assess the accessibility of different sanitation facilities, and to explore the sanitation standards of the sanitation facilities in relation to the recommended Humanitarian Sphere Standards in the area. Pit latrines, hand washing facilities, and solid waste disposal areas as reported by 81.4%, 86.7%, and 51.9% of the respondents respectively, are the main sanitation facilities accessed in the refugee camp. Despite their accessibility, the standards of the pit latrines, hand washing, and solid waste disposal facilities are below the recommended standards, which might have contributed to the outbreak of sanitation related diseases (χ2 = 19.66, df = 1, P = 0.05) in Bidibidi refugee camp. The respondents in the study area were aware that the presence of the sanitation-related diseases was because of the low-level sanitation practices in place (χ2 = 4.54, df = 1, P = 0.05). The inaccessibility to some sanitation facilities by some respondents was found to be related to their low level of education (χ2 = 130.37, df = 1, P = 0.05). This implies that the sanitation facilities in Bidibidi refugee camp need to be redesigned and improved especially the pit latrines and the solid waste disposal facilities in order to meet the minimum Humanitarian Sphere Standards. Also, there should be more provision of taps with flowing water in the camp for effective washing practices to minimize the spread of sanitation-related diseases.

Landslides, whether induced by nature, or human activities, are one of the most prominent disasters which are of great concern in the world. They cause a lot of havoc to the environment hence a necessity to avoid them whenever possible. This literature review is basically aimed at finding out how Geographical Information System (GIS) and Remote Sensing (RS) technologies are used in avoiding landslides and risks associated with them at different levels; Challenges encountered while using GIS and RS techniques for landslide disaster risk reduction are identified; and therefore, dealing with them requires the involvement of developed countries who have the capacity to provide the necessary equipment to the developing countries that are faced with disasters. This study discusses the use of GIS and RS in mitigation of risks from landslides, and mainly points out how these techniques are applied to avoid disaster risks.  Secondary data was reviewed from journal articles, institutional reports, and online publications from similar studies. GIS and RS tools are important in predicting, monitoring and managing landslide disasters.  It was concluded that GIS and RS tools provide cheaper, reliable, and faster techniques of accessing spatial data in a given area, therefore regarded as essential technologies that may be necessary for predicting landslide occurrences, these technologies need to be considered in communities which are prone to landslides.

Food is a basic right of all people, however, food security in Africa is being threatened. The main objective of this article is to uncover the causes and implications of food insecurity in Africa. The information was mainly obtained by reviewing literature with similar topics. Food security and food insecurity are both used to find out if people can or cannot access enough food. Poverty, COVID-19, war and conflict, and climate change have major impacts on food security and this is explored in more detail in this article. Improved food security is very vital for a wider reduction of hunger and helps to overcome undernourishment, malnutrition, domestic violence, and poverty. The causes and implications of food insecurity in Africa need to be addressed to ensure that Africa is freed from hunger.
