Impact of climate change on domestic water accessibility in Bamenda III Sub-Division, North West region, Cameroon

The effects of climate change are felt most at the household level, when taps and springs run dry for several weeks or months, forcing people to access potable water from doubtful sources. There has been an increase in the population of Bamenda III without a proportionate increase in the water supply capacity. This has resulted in severe water crises, even though Bamenda III municipality has water supplies from the Council, Community, CAMWATER, natural springs and streams, wells and boreholes. Household data on water accessibility against a backdrop of a changing climate was collected using 269 questionnaires to assess perceptions on the state of water resources and climate. Rainfall data were collected from 1963-2019 and results revealed that mean annual rainfall is at 182.52 mm, with a standard deviation of 29.16 and a Coefficient of Variation of 15.69%, while the mean Standardized Precipitation Index is -0.07 (mild dryness), and rainfall has reduced by -2.07 mm from 1963-2019. The population attributed problems of water accessibility to climate change, urbanization and poor water governance. It is recommended that sustainable water management through Nature-based Solutions and Ecosystem-based Adaptation should be implemented from the watershed to the community level

Farm-based climate adaptation dynamics: insights from the vegetable sector in the Western Highlands of Cameroon

Agro-based climate adaptation has gained traction in scholarly and policy circles, albeit with limited comprehensive empirical evidence on the pathways of crop sector-specific adaptation approaches in sub-Saharan Africa (SSA). To stem this knowledge gap, this study examines the evolution of farm-based climate adaptation practices in the vegetable subsector of Cameroon’s western highlands. Specifically, we (i) explore the different adaptation practices, (ii) estimate the determinants of farm-based adaptation, and (iii) determine the effects of farm-based adaptation on vegetable performance. Data were collected from a representative sample of farming households (N = 150) in two communities using a semi-structured questionnaire, complemented by key informant interviews (N = 10) and focus group discussions (N = 5). The Product Moment Correlation established an evolution from traditional practices to more modern scientific practices with changing climate, as vegetable farmers shifted from using local seeds to improved ones, intensified pest control strategies and adopted water pump-based irrigation practices. The binary logistic regression model revealed that belonging to farming groups, increase in income and access to credit significantly explained farm-based adaptation (p = 0.041). Furthermore, farm-based practices were significantly reflected in crop performance, mirrored through an increase in vegetable quantity (p = 0.003) and perceived quality (p = 0.046). The results suggest the need for further research to blend traditional and conventional adaptation approaches, and to create enabling environments to foster social capital (belonging to groups) and access to credit as key levers for climate-resilient vegetable production in the western highlands of Cameroon

Indigenous Knowledge and Farmer Perceptions of Climate and Ecological Changes in the Bamenda Highlands of Cameroon: Insights from the Bui Plateau

Anticipating seasonal and shorter time scale dynamics to farming practices is primordial for indigenous farmers’ resilience under extreme environmental conditions, where climate change is a menace to agro-hydro-ecological systems. This paper assesses the effectiveness of indigenous farmers’ knowledge and aptitude to read weather signs for informed decisions on their daily and seasonal activities. Such climate-proof development is anchored on indigenous people’s knowledge and perceptions in circumstances where the dearth of scientific evidence or information exists as in Cameroon. The study is based on eight focus group discussions and a survey of 597 farming households in seven agro-ecological basins on the Bui Plateau of the Bamenda Highlands. The results indicate that indigenous smallholder farmers value their ability to accurately observe and anticipate local conditions in various ways to serve their local realities more aptly than outside forecasts. Such local knowledge should thus exercise a complementary role weave in a local climate information understanding system that replicates ecological variability

Rainfall reliability and maize production in the Bamenda Highlands of Cameroon

The long-term average rainfall for a given period (month, season or year) scarcely indicates reliability because rainfall in low latitudes varies significantly from one year to the other. The less variable rainfall is, the more reliable it is, as the index of variability measures the likelihood of repetition in the mean amount of rainfall. This study bridges some gaps in related studies in the Bamenda Highlands, such as a study assessing climate change impacts on food security, where the Rainfall Anomaly Index was used and another study on the impact of rainfall on maize production using the Standardized Precipitation Index. The objectives of this study are to assess rainfall reliability and establish the impact of rainfall reliability on maize production. Rainfall data were collected from 15 stations, while maize output was collected for four localities. Results revealed that rainfall is still reliable for 13 stations, with a coefficient of variations of 9.62 to 18.54 %, while Ndop and Ndawara recorded unreliable rainfall of 23.14 % and 30.97 % respectively. Rainfall reliability was complemented by the Standardized Precipitation Index, which showed that only 53.45 % of rainfall episodes were normal to sustain maize production, while 46.55 % were events of rainfall deficits. Maize production has been decreasing in Ndu, Oku and Nkum while increasing in Ndop. These findings reflect the realities of other tropical mountainous regions in the world. Faced with future climatic uncertainties, farmers should embrace agroecological practices, climate-smart agriculture, conservation agriculture, Nature-based Solutions, Ecosystem-based Adaptation and diversification of production systems and livelihood sources to ensure food security

Data_Sheet_1_An overview of climate change adaptation and mitigation research in Africa.PDF

Research on climate change has increased significantly since the 1970s. There has also been a particular focus on Africa, given its vulnerability to climate change impacts and its urbanization trends that may have massive implications for climate change adaptation and mitigation. Despite the wealth of publications on climate change in Africa, there is a lack of review studies that highlight the overall research landscape. If this status of climate research is clarified, African countries can better deal with climate change. Hence, this paper aims to improve our understanding of the status and trends of research on climate change adaptation and mitigation in Africa. Our review, straddling from 1990 to late 2021, recognizes the foundations that underpin climate change adaptation and mitigation literature. Based on keywords associated with Africa's climate change adaptation and mitigation, we undertook bibliometric research by collecting 3,316 related SCI/SSCI articles. In addition, we provided a thematic evolution over three decades, compartmentalized into four sub-periods (1990–2007; 2008–2014; 2015–2019; 2020–2021). Priority research topics and themes have been dynamic over time, with some core concepts receiving more attention (vulnerability, food, water, and energy security). Although the number of published articles exhibited a rapidly growing trend, their distribution is extremely uneven. Articles were mainly published by institutions from certain parts of the continent, with the University of Cape Town, making the highest contribution. About 72% of the existing studies focused on climate change adaptation, while climate change mitigation was less represented with 22%. The results also showed that researchers have examined not all African countries. South Africa, Ethiopia, and Ghana are hot spots, while most countries are largely neglected. Africa and African countries need to improve their future research ability on climate change mitigation. Assessing climate change risks and measures in African countries should be prioritized.</p

Place-based capacity building to enhance resilience in tropical countries

Countries located in the tropics are among the most vulnerable to climate change and will be home to more than half of the world's population by 2050. Many of these regions are already experiencing a variety of climate-change-induced stresses and in many cases lack the capacity to adjust, adapt, and survive. This Voices asks: how can we strengthen locally led capacity building to enhance tropical resilience for a sustainable future
