Water resources in northern Cameroon have continuously been reducing over the past years. Many studies have suggested two principal causes: (1) human activities such as poor farming practices, unsustainable use of water resources, increased demand of water, deforestation, land-use change, etc., (2) human-induced climate change. Northern Cameroon in...

Floods are among the most severe natural disasters, capable of causing significant damage to both the environment and society. This research utilizes the Gumbel distribution to analyze flood return levels by examining historical data from Niamey, Niger. The study focuses on river heights, flow rates, and precipitation patterns to understand the dyn...

Improving access to and use of renewable energy (SDG 7), increasing reliable water supply (SDG 6), enabling irrigation and digital technologies in agriculture, and operations for food preservation (SDG 2) are activities focused on the three Sustainable Development Goals (SDGs), pillars of this chapter. There is a great potential to expand these SDG...

Increasing rainfall frequency and intensity, which causes floods, is one effect of climate change. Recent heavy rains have caused regular flooding in several major towns in West Africa. ln order to comprehend the cyclical patterns of flash floods and very high rainfall occurrences in Niamey, Niger, between 1982 and 2021. The National Meteorological...

The increase in population leads to a need for housing and agricultural land. As a result, some areas are being modified to meet these needs. In addition, rapid growth combined with the negative impacts of climate change observed in recent decades, plays an important role in land use changes. This study examines land use changes in Niamey, Niger, f...

Flood events are recognized to be one of the most among the most catastrophic disaster in the world, with a consequential loss of lives, goods, and services. Factors such as rapid urbanization, lack of proper infrastructure development, insufficient consideration of the environment, and the effect of climate change have made floods even more destru...

The projected increase in demand for food, water, and energy owing to systemic shocks has heightened the need for innovative solutions and integrated resource governance. Innovative technological frames such as the Agrovoltaics for Mali and Gambia (APV MaGa) Project focuses on sustainable electricity production leveraged with digital technologies....

The research ecosystem in sub-Saharan Africa is changing. Organised around new centres of scientific excellence, the sub-continent is building a research agenda aimed toward major development challenges and the achievement of the sustainable development goals. Thus, strengthening doctoral programs and their beneficiaries becomes crucial in supporti...

Small-scale, rain-fed subsistence agriculture and pastoralism represent the major activity for Africa. For Mali, this represents about 80% of the population employed by the agricultural sector and contributes to about 42% of the Gross domestic product (GDP). The overreliance on rainfall, competing for the most valuable lands, the increasing scarcit...

Groundwater is an important resource for food production, drinking water supply, drought mitigation, and economic development especially for rural communities around the world. The rapid expansion in agricultural groundwater use in the last few decades has transformed rural economies in large parts of the developing world, in particular South Asia...

Pan-African University (PAU) is an initiative of the African Union Commission (AUC) that started in 2008 with the objective to promote higher education, science and technology on the African continent at a high academic level. The Pan-African University Institute of Water and Energy Sciences (including Climate Change) (PAUWES) is one of the five hu...

The Research-2-Practice Forum aims to provide a platform for experts active in applied and practiceoriented research in the areas of renewable energy, water and climate security to engage in an active exchange and to build strategic partnerships. It will take place from 16-18 April 2018 Tlemcen, Algeria. Applications can be submitted until 8th Janu...

The Far-North region of Cameroon is threatened by extreme water shortage and climate variability. Visible evidences of water problems in the region includes; a total crop failure because of drought; heavy rainfall and flooding; shrinking of Lake Chad etc. Many studies have attributed these calamities to two possible causes and this includes: human...

The Far-North region of Cameroon is threatened by extreme water shortage. Over the years groundwater has increasingly been used as the main source of domestic water supply. In spite of the increased, groundwater exploitation has been done without adequate planning. One of the key parameters of a sustainable groundwater management is the regional gr...

Many studies have been conducted to illustrate changes in annual rainfall but not so often for the seasonal changes. With water harvesting often recommended as an effective adaptation strategy to cope with climate change, the seasonal changes of rainfall might reduce the efficiency of the facility if not well understood. The concern here is that ru...

Estimating water balance of an area is essential for predicting water yield, designing irrigation and supply projects, managing water resources and their associated environmental concerns, and resolving disputes, contracts, or treaties involving water. The Far-North region is threatened by water shortage and climate variability. There is an urgent...

The role of water harvesting as a strategy in adapting to the current climatic variability and change has really not been exploited in the Far North region of Cameroon. The region is threatened by water shortage and climate variability. This paper seeks to emphasize the availability of sufficient water which could be harvested to ensure water secur...

During the late 1980s, the Cameroonian cocoa sector was controlled by the government in their attempt to stabilise farm income by setting an average purchase price for raw cocoa. This system collapsed around 1987, when there was a drastic fall in the world price of cocoa and the government could not stabilise the market using its traditional suppor...
