In the next few decades a large increase in population is expected to occur on the African continent, leading to a doubling of the current population, which will reach 2.5 billion by 2050. At the same time, Africa is experiencing substantial economic growth. As a result, air pollution and greenhouse gas emissions will increase considerably with significant health impacts to people in Africa. In the decades ahead, Africa’s contribution to climate change and air pollution will become...

Climate change has a significant impact on urban green areas, and its surrounding environments. Public parks had been negatively affected in various aspects including landscaping conditions such as planting design within parks, the need for irrigation, declining of green coverages, mass loss of trees, in addition to the physical activities of visitors including active playing of children, walking, running, playing sports, also the psychological comfort and socializing of visitors. In order...

The challenges of climate change in West Africa are closely linked to food security in the region. Rising temperatures and increasingly variable precipitation threaten traditional rain-fed agriculture relying on the rainy season. Climate change is affecting the rainy season in West Africa in multiple ways, e.g., by shifting the onset, shortening its duration and increasingly interrupting the growing period by dry spells. An increase of extreme weather events such as heavy precipitation or...

The climate in Africa is very diverse ranging from tropical rainforest to deserts. Also, East Africa is covered by different climate zones and is very dry compared to other tropical regions. This is owed to various large-scale drivers, such as the complex topography, large water bodies such as Lake Victoria and vicinity to the Indian Ocean. The southern part of East Africa is characterized by two rainy seasons, which are separated by dry periods. The long rains from March to May feature more...

This study aimed to investigate the role of school heads in fostering teamwork among secondary school teachers in Nyamagana district, Mwanza region, Tanzania. The study was guided by three specific objectives: exploring the significance of teamwork among community secondary school teachers, examining the strategies employed by school heads to promote teacher teamwork, and identifying the challenges they face in this endeavor. Utilizing a qualitative research approach and a case study design,...

Climate change is a concern of our time, both at global level and at community level, where its impacts vary according to context. According to the Intergovernmental Panel on Climate Change (IPCC), the causes of this change are anthropogenic and require urgent action on the part of humanity in terms of mitigation but also in terms of adaptation to strengthen the resilience of populations. The municipality of Namissiguima (13° 36′ 00″ north and 2° 13′01″ west), in the province of Yat Enga in...

This research work was carried out in Sudan savanna of Kwara State to determine the effects of land use types on soil carbon pool, loss, emission and to determine the farmer’s knowledge level and sources of information on climate change. Six villages were selected randomly and in each Local Government Area, three villages were visited and three farms planted each with maize/cassava intercrop, cashew plantation and natural forest were sampled. Soil samples were collected from the farmland...

Climate models have shown that there will be an increasing susceptibility to drought in the future for semi-arid regions. However, the impact of these droughts depends on the sensitivity of landscapes and the adaptive capacity of communities. Using a vulnerability framework, and a mixed-methods approach, this paper assesses the vulnerability of the social-ecological systems along a rainfall gradient transect in southwest (SW) Madagascar at multiple timescales. We used a transdisciplinary...

Based on the IPCC AR6 Report, the southern African climate change signal is projected to have a rapid warming compared to the global signal. A decreasing trend in the observed mean precipitation can already be detected in most of southern Africa and an increasing trend in heavy precipitation in eastern southern Africa. While some areas are experiencing increased rainfall and flood risks, other regions are facing reduced rainfall and more frequent droughts. These changes are projected to...

This article evinces that policies and plans at the national level in South Africa recognise the importance of postgraduate education within the broader national education and training system, and that they place particular emphasis on promoting access to, and success in postgraduate education as one of the priorities on the country’s development agenda. It identifies and discusses ten issues that have a bearing on the national policies, plans, programmes and initiatives aimed at promoting...

Tropical montane cloud forest ecosystems contain some of the world's biodiversity hotspots and provide essential ecosystem services, including high quality freshwater and microclimate buffering against climate extremes. The microclimate buffering service provides microrefugia that allow species to persist under climate change, while the ability of montane forests to intercept cloud water from the atmosphere maintains freshwater availability. However, with increasing pressure from...

Miniaturised air sensors (otherwise known as “small sensors”, “low cost sensors” or “lower capital cost sensors”) have been used extensively for air quality campaigns globally primarily as pilot studies. To date, their usefulness for applications to generate robust evidence for social intervention programmes, especially in geographies with poor environmental and social policies (such as those encountered in many parts of the global...

The pandemic has undoubtedly forced educational systems across the world to change face-to-face education practices forever. On the other hand, it has also forced online education system practices among Moroccan higher education institutions. With the spread of COVID-19 all over, the Moroccan education system circumstances did not allow face-to-face education, nor did it allow online education as a solution. As a matter of fact, hybrid learning remains the best-proposed alternative, as...

Abstract Many volcanic landscapes reflect the essence of volcanism and are particularly attractive to different kinds of visitors, featuring the concept of volcanic geoheritage. The expressiveness of volcanic processes is exacerbated in active volcanoes, which increasingly attracts geotourism, despite the natural hazards associated to such geological environment. This work reports how the 2014–2015 eruption of the Fogo volcano at Cabo Verde (West Africa) affected the geoheritage of the...

Climate change has different impacts on water resources, altering hydrological cycles and exacerbating water-related challenges. Changes in precipitation patterns, including more frequent and intense droughts in semi-arid areas contribute to water scarcity and unpredictable availability. Being situated in central-western Morocco, the Souss basin (SB) is subject to high variations on many different scales and is strongly influenced not only by the variability of the climate but also by...
