Modelling Climate - Surface Hydrology Interactions in Data Sparse Areas. Since the ca. Historical Sea Surface Temperature data set (MOHSST)1,2 we This means that around 8 million people obtained access to an improved water source over this period. Primary data was collected through questionnaires, key informant interviews and field observations while population, climate and hydrological data are also analyzed. The report from UNICEF (2010), in the world 884 million people use unimproved drinking water sources in 2010, and in 2015 estimates about 672 million people will still using unimproved drinking water sources. Cameroon Geographic Review 5(1), Yaounde University. The results suggest that the impacts of LULCC on watershed hydrology are easily detected in small sub-watersheds than in large sub-watersheds. Surface water is constantly replenished through precipitation, and lost through evaporation and seepage into ground water supplies. The likelihood of cassava cyanide intoxication was also increased on fields with high pH and iron levels. Cambridge: Cambridge University Press. Bamenda: Unique Printers, pp. The Effect of Climate Change on Water Resources and Programs Introduction The goal of this module is to educate water program managers, as well as the general public, on the expected effects of climate change on water resources and water programs. Dr Kirsty Upton and Brighid Ó Dochartaigh, British Geological Survey, UK Dr Imogen Bellwood-Howard, Institute of Development Studies, UK Please cite this page as: Upton, Ó Dochartaigh & Bellwood-Howard, 2018. The two villages of Alim-Boyui presently have no access to clean drinking water. Therefore, the magnitude of dense forest cover loss must be significantly greater than 16% to cause significant changes and common trends in the hydrology of the sub-watersheds of the southern portion of the Nyong River basin. The WHO (2000) revealed Cameroon agree that rainfall has decreased. Subsidiary of the SABC, the SEMC is ISO 9001 2008 certified. more than a natural long-term persistent dry spell or oscillation. In Lambi, CM (ed. This study aimed to characterize quality of water sources and explore potential environmental reservoirs of the causative agent, Vibrio cholerae, and factors maintaining its persistence. In Cameroon, low rainfall has led to a sequential occurrence of cumulative and over-time droughts and floods (Molua and Lambi, 2006). Accessed [date you accessed the information]. Cameroon - Cameroon - Plant and animal life: The hot and humid south supports dense rainforests in which hardwood evergreen trees—including mahogany, ebony, obeche, dibetu, and sapelli—may grow more than 200 feet (60 metres) tall. Climatology of West Africa. This has been described as an environmental terrorism. Climate Change 1992: The Supplementary Report to the IPCC Scientific Assessment Intergovernmental Panel on Climate Change The impact of human activity on land degradation in some highland regions of Cameroon: Implications for development. Such temporal specialization can make the local communities of butterflies and moths especially sensitive to the expected seasonal perturbations caused by the global change. 2008). In order to cope with inadequate water, community members and public institutions in the study area have drilled boreholes and the sustainability of groundwater in the area is not well established. Abiotic soil properties (pH, clay content) strongly influenced microbial habitat properties and thus had a positive effect on the CO2 efflux, irrespective of glucose addition. A mixed methods research design was employed using qualitative methods such as content analysis whilst quantitative methods were dominated by time series analysis techniques and online interactive climate platforms such as the Climate Engine. In August, there is regular, western edge of the southern plateau, with Yokadouma recording 166mm and Yaounde. Remarques sur la situation pluviometrique actuelle au Nord Cameroun. Precipitation Rate 1: 1 600 mm/year. These stem from two main factors: first, the variability of past climatic conditions in the arid zones, with resultant uncertainties as to how much of the present scenery is truly the product of present-day conditions and processes, and how much represents legacies from different conditions in the past; and, secondly, considerable deficiencies in our knowledge of the character and rates of the 'arid' processes operating today. Despite the multiple soil nutrient deficiencies on crop fields, low soil fertility was however not the only probable cause of increased cyanogenic glucosides in cassava, as high soil nutrient levels were also found to be potential contributors. Climate Change 1992: The Supplementary Report to the IPCC Scientific Assessment. the people in the rural areas of the north. Remarques sur la situation pluviometrique actuelle au Nord Cameroun. Although not coastal, konzo-affected areas in Bandundu province in DRC, located in the Savannah zone, primarily consist of relatively infertile soils . mineral water is produced by the Société des Eaux Minérales du Cameroun. There are four seasons—a light rainy season from May to June, a short dry season from July to October, a heavy rainy season from October to November, and a long dry season from December to May. This visualization provides a high-resolution, three-dimensional view of global atmospheric carbon dioxide concentrations from September 1, 2014 to August 31, 2015. Population: 16 296 000. Our multitaxa approach covered six lepidopteran groups (fruitâfeeding butterflies and moths, the families Sphingidae, Saturniidae, and Eupterotidae, and the subfamily Arctiinae of Erebidae) with diverse life strategies. In each case attention is directed to our present lack of adequate quantitative data, and to recurrent uncertainties as to the age of features and hence as to whether they are truly the product of current aridity or in large measure inheritances from the past. The Bamenda Highlands contains numerous dilute and soda springs of unknown hydrological provenance. Hydrological processes and water resources.

Cameroon plans to increase Yaounde’s water supply to … These changes in vegetation affect the type and amount of food available for humans and other organisms. The results reveal spatially varying trends of stream discharge, low flows and high flows among the sub-watersheds with LULCC within the study watershed. Water Resources in Cameroon. Various types of water sources are presented which are largely what determine water availability. Soil nutrient supply in these areas could also be influencing cyanogenic glucoside production in cassava, however there is hardly any knowledge on this. ... Molua and Lambi (2006) highlighted that climatic information has revealed that over the years, rainfall has been on the decline. This service shows you Sources of Drinking Water in Cameroon on an interactive map. This decrease can be explained by the fact that 2012 was marked by the arrival of new operators in Cameroon mineral water market. There is visible evidence of the effects of these droughts: drop in electricity production at the Ladgo hydro-electric power plant. Nevertheless, how the outbreak takes place and how the disease is spread in the region remain largely unknown. These floods have always been preceded by a period of. Breakdown of Total Actual Renewable Water Resources the decrease would depend on the soil type and the underlying geology. To fill this gap, we investigated biodiversity patterns of Lepidoptera communities at three rainforest localities in the foothills of Mount Cameroon, West Africa, one of the wettest places in the world. water. Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. Modern Geography of the Republic of Cameroon. 65â73. This study characterises the microbial activities and functioning in rhizosphere soils of the four legumes Phaseolus vulgaris L., Glycine max L., Arachis hypogea L. and Vigna subterranea L. in a laboratory incubation experiment. Pure Aqua provides wide range of filtration and economical solutions based on the Cameroon’s water resources. Cameroon’s location on the Atlantic coast in central Africa between latitude 2° and 13°north, has a huge and diversified water resources potential. ), Environmental Issues: Problems and Prospects. 283 billion m³/year. Cyanogenic glucoside levels in cassava roots however increased by high levels soil phosphorous (rs = 0.486, p = 0.026 for all varieties) and sulphur (rs = 0.593, p = 0.032 and rs = 0.714, p = 0.047; for bitter and sweet cassava varieties, respectively) on these soils. well as the impact of human activities on the pattern of flow is indispensable. The meteoric recharge and similar residence time of the shallow dilute springs suggested natural resilience to short-term changes in climatic conditions. timescales of years to tens of years, which are most pronounced in the 2018. extremely high discharge during the rainy season equally reflects the i. part of the country and this has equally affected other human activities. The risk of cassava cyanide intoxication occurring (and thus high cyanogenic glucoside levels in cassava) was found to be likely increased by cultivating cassava on soils with high pH (XÂ² = 8.124, p = 0.004) and high iron (XÂ² = 5.740, p = 0.017). Thompson R, 1998. of petrol and unlawful discharge of toxic wastes expose this zone to pollut, limit of the Adamawa Province. As income levels have risen globally, so has the demand for With 208 km 3 of renewable water resources, only 1 km 3 is used for drinking water. The conclusion stresses the complexity and variability of arid landscapes and the dangers of generalizing about them too freely. almost entirely from the southern low plateau. Africa Groundwater Atlas: Hydrogeology of Cameroon. eucalyptus tree consumes water voraciously, leaving none for other plant. Community members must trek to a stream in order to collect their drinking water-- thus leaving many to drinking dirty water. El NiÃ±o events may also In Lambi, CM (ed. We assessed the WF of hydroelectricity by three different methods using New Zealand as a case study. In the well watered southern region (see Figure 1), which has metamorphic and. Mineral water in Cameroon. attendant electricity rationing policy, would be intensified. Introduction: The ecological zones of Cameroon. The microbial biomass was lowest after the experiment in the soil from the High Guinean Savannah except for soils under soybean cultivation. which is at the southern fringes of the Sahara Desert. north was preceded by a long predominantly dry period from 1981â1987. Soils in the non-coastal Eastern region of Cameroon are additionally described as having a sandy clay texture and as being largely degraded, Introduction to Climatology for the Tropics A quantitative evaluation of global warming and precipitation in Cameroon from 1930 to 1995 and projections to 2060: Effects on environment and water resources. Bamenda: Unique Printers, pp. Within the set of tested legumes, soybean cultivation can, therefore, be strongly recommended as a long-term sustainable crop to boost soil microbial functioning and probably also nutrient cycling, especially under low total organic carbon stocks. Day to day challenges of accessing water from distant boreholes and rivers are a reality particularly for women and children in rural Limpopo. Seasonal effects. Measure the economic impact of climate change on African agriculture and analyse farmers' adaptation strategies, Malaria is the most important cause of mortality of persons and health Insurance is a way to pay for health care, by protecting persons from paying the full costs of medical services . amount of sunshine as a result of cloudless skies during this period. Nonsignificant trends in total discharge, high flows, and low flows were observed in the large sub-watersheds of Mbalmayo and Olama from 1998 to 2013 with LULCC within the watershed. After the flood had receded, we noticed the damage: electronics were destroyed, drinking water was contaminated, and other valuables were water damaged. In, system. The decrease in dense forest cover at 0.6% per year on average was driven by indiscriminate expansion of subsistence agricultural/cropland through shifting and fallow cultivation farming systems. The soil nutrient levels in these areas, could also be influencing cyanogenic glucoside production in cultivated cassava, however there is hardly any knowledge on this. From the start to the end of the Millennium Development Goals, access to better water sources in the country increased by a total of 19 percent. Conversely, the old soda springs displayed piston flow and binary mixing models. Â© 2003 by the University Press of Colorado. pp. In Cameroon, low rainfall has led to a sequential occurrence of cumulative and over-time droughts and floods. High levels of sulphur and phosphorus, to very high levels of iron occurred on some fields. Closely linked to this is the element, means that the groundwater does not get sufficiently recharged, and so there are fewer. Climate and Environmental Systems. This study investigates the nature and extent of water supply problems and how communities are living without adequate water in three rural communities of Greater-Giyani Local Municipality in South Africa. It is estimated that this basin receives about 45 bill. water rose from 50 percent in 1990 to 74 percent in 2008. This observation has led researchers to. Despite these challenges which are not well documented, it was concluded that most of the rural poor households and institutions in the study area are well adapted to cope with water scarcity in the short term, while being vulnerable in the long term due to population growth and climate change. More disturbingly, the World Health Organization has reported that 1 billion people lack enough water to simply meet their basic needs, unfortunately in many countries water is scarce or contaminated. SF6 concentrations in dilute springs revealed exceptionally young ages relative to CFCs modelled ages suggesting a terrigenous enrichment of the former. Rainfall ranges from 800 to 900 mm annually, arriving within the months of July to October, while the remaining eight months are dry, ... Rainfall ranges from 800 to 900 mm annually, arriving within the months of July to October, while the remaining eight months are dry . Although not coastal, konzo affected areas in Bandundu Region in DRC are located in the Savannah zone, which primarily consists of relatively infertile sandy soils [19,20]. Depending on the method, the national WF ranged from 1.55 m3 GJâ1 (WF-3) to 6.05 m3 GJâ1 (WF-1). These dilute springs are a vital source of drinking water to the inhabitants. Surface water is water that collects on the ground or in a stream, river, lake, reservoir, or ocean. Source Tangi recorded a decrease of 15.7% compared to 2011. Irrespective of, This chapter reports the main results of a workshop held in Boulder, Colorado, on June 21-22, 1999. Many rural communities of South Africa are living without adequate water supplies mainly due to historical lack of infrastructure and effective water reticulation systems. The use of chlorine treated water, improvement in sanitation structures and hygiene are possible solutions to reduce cholera outbreaks. Beauvilain A, 1985. Lake Chad is rapidly shrinking and its shores are drying up. Simultaneously, we revealed a strong species turnover of fruitâfeeding Lepidoptera and Arctiinae among the seasons, indicating relatively high specialization of these communities for particular seasons. This, c) but the annual range is relatively high (7.7, the dry season from November to March and the rainy season from A, north, forcing the Intertropical Convergence Zone (ITCZ) towards the Bamileke, Cameroon at this time has a zone of high rainfall of 150mm to, respectively. Cameroon is essentially an agricultural economy since approxi, Sahelian zone of Cameroon largely depends on the amount of rainfall rece, Cameroon. The flow pattern of, because the distribution of rainfall is. These zones correspond to West, Northwest (Western highlands) and Adamawa (Guinean Savannah Highlands) regions of Cameroon. Cameroon possesses vast water r esources, i n the f orm of groundwate r and stream or surface water. Simply browse with your mouse through all regions, or swiftly use the search function or the list view with the 7 states of Cameroon. 8.2 Causes of climatic variation and climatic change in North Cameroon, circulation of the atmosphere (Ayoade. This climatic type, like its equatorial, Cameroonâs volcanic massif comes close to the coast. There was extensive and intense drying up of vegetation and scarcity of natural, Total crop failure in January of 1984 necessitated the distribution, Introduction to Climatology for the Tropics, Modern Geography of the Republic of Cameroon, Applied Climatology: Principles and Practice. Thus, groundwater dating with SF6 is unreliable in the area. 45â 66. WMO & UNEP (World Meteorological Organization & United Nations Environment Programme), Intergovernmental Panel on Climate Change. The overall, The hydrological cycle is interactively integral with climate, so that for an understanding of future environmental change it is important to have hydrological data accessible from previous times to use in both hydrological and climate change modelling of past, and also of present and future environments and also for the development and operation of surface water resources. As a contribution to water management, this study investigated the spring water recharge, residence time and sub-surface circulation using Î´18O, Î´D, 3H, CFCs, SF6 and TDS. This is because eucalyptus has a deep rooting system, which can penetrate right to the water table and cause evapotranspiration. Most dilute springs showed exponential mixing models indicating heterogeneous recharge under unconfined aquifer conditions. Atlantic. London: Hutchinson. London: Unwin Hyman. 9. Hayward R & Oguntoyinbo J, 1987. Interested in research on Water Resources? Our sampling included standardized bait trapping (80 traps exposed for 10 days per locality and season) and attraction by light (six full nights per locality and season). Consumption of natural mineral water in Cameroon experienced a decline, with only 700,000 hectoliters sold in 2012. An assessment of soil nutrient levels on crop fields in konzo-affected areas was therefore carried out to determine their adequacy for optimal cassava growth. High-risk zones of cholera were identified which could be used to inform local risk. the peak period of rainfall of AugustâSept, floods of 1988 were quite spectacular, with considerable damage caused to houses and. northern region have been significantly, caused not only by deterioration in the climate but also by dams and groundwate, 7. and the advance of the desert towards the more humid lands. Per Capita in 2005 : 17 520 m 3 /year. We do not discount the effects of soil moisture and albedo Cumulative glucose respiration increased over time, and glucose pulses repeatedly boosted glucose respiration and total respiration at all sites. Mangroves grow along the coasts and at the mouths of rivers. The Mann-Kendall and Regression approaches show appreciable potential for modelling the impacts of LULCC on the hydrology of the southern portion of the Nyong River basin and for informing forest management. A brief review of terrestrial aridity throughout geological time, and of the geological criteria of past aridity, is followed by a summary of current ideas on the climatic history of the Sahara and of the evidence upon which these are based. Over time, the dominant source of water to a well, particularly wells that are completed in an unconfined aquifer, commonly changes from ground-water storage to surface water. The results showed that cassava grows under conditions of severe nutrient stress in the region. Local values, calculated using our hydrologically rational method, must be used. This study aims to analyze the influence of various land use types on the water quality within the Chaohu Lake Basin based on the water quality monitoring data and RS data from 2000 to 2008, with the small watershed as the basic unit of analysis. ), Environmental Issues: Problems and Prospects. The results also showed that cyanogenic glucosides in cassava roots could be increased with the increased supply of sulphur in soils in bitter cassava varieties (rs = 0.593, p = 0.032), and with the increased supply of P in soils in all cassava varieties (rs = 0.486, p = 0.026). A monsoon (/ m ɒ n ˈ s uː n /) is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea. relatively greater variability in rainfall and stream flow. River and groundwater hydrology are beyond the scope of this manual, so that only a conceptual example is provided. provides the drainage divide between the two, rivers from at least two catchment areas (Figure 5). London: Routledge. London: Unwin Hyman. It provides meaningful information that helps our understanding of the differences of the WF in locations, which are diverse in terms of water resource availability. was marked by the arrival of new operators. The household size was shown to be a significant risk factor for reported cholera cases (P<0.05). Neba A, 1999. Debu, low-lying coast, the annual average temperatures climb to 25.5, the tropical humid type (Sudan climate). Among the four legumes cultivated, only soybeans strongly increased microbial biomass in the High Guinean savannah reaching even the level of microbial biomass in Western Highland soils. The cost to build, distribute, and install a BioSand water filter is $50, which in turn benefits an average of … In North Cameroon, cholera outbreaks regularly occur during the rainy season. atmospheric circulation3-6. Carbon dioxide is the most important greenhouse gas released to the atmosphere through human activities. These changing land use patterns (deforestation, overgrazing, reforestation, urbanisation, etc.) Seasonal Water Sources. Logistic regression analysis was used in the latter investigation. Failed rains see dry seasons tip into droughts, leading to already limited natural water sources like rivers to dry up. Ibadan: Spectrum. equally altered the atmospheric energy balance. A plot of both water types along the local meteoric water line indicated the meteoric origin and rapid recharge following precipitation. place of water in the soil-plant-atmosphere continuum is primary in the life cycle of plants. New York: Routledge. The Nyong River basin is one of the several major drainage basins in Cameroon feeding the Atlantic Ocean and a major source of water resource for the local population in the southeast, central and south regions of Cameroon. Potential impact of climate change on hydrological processes. Springs on which people depe. Atlantic and Congo basins are not relevant to this project on climate change. Some efforts being made to better Cameroon’s water quality have proven to be successful. The water footprint of hydroelectricity: A methodological comparison from a case study in New Zealan... Has modeling of water resources on the basis of climate and hydrology reached its full potential? Because of the key role of Lepidoptera across trophic levels, such changes in their communities could strengthen this impact on entire tropical ecosystems. In contrast, significant decreasing trends in stream discharge (up to â5.1% and â5.9%), and significant increasing trends in high flows (up to 2.1% and 6.3%), respectively, were observed in the small sub-watersheds of Pont Soâo and Messam from 1998 to 2013, particularly with increase in agricultural/cropland cover and decrease in dense forest cover. Altogether, our dataset comprised 20,576 specimens belonging to 559 (morpho)species of the focal groups. There have been some researches on this relationship from the perspective of the spatial configuration of land use in recent years. Copyright © 2014-2018. The results revealed that most soil nutrients known to have reducing effects on cassava cyanogenic glucosides, like potassium (mean = 0.09 cmol/kg, SD = 0.05 cmol/kg), magnesium (mean = 0.26 cmol/kg, SD = 0.14 cmol/kg) and zinc (mean = 1.34 mg/kg, SD = 0.26 mg/kg) were deficient on several crop fields.
