The Impact

Water resources within Bamenda continue to face climate related stress. This paper sought to assess the impact of climate variability and change on water resources in Bamenda metropolis. Questionnaires, field study and historic climatic data were used to evaluate effects of climatic variability and changes on water resources. Two Representative Concentration Pathway (RCP 2.6 and RCP 8.5) scenarios were used to project climatic data. Standardised Precipitation Index (SPI) was used to determine drought. Irregular rainfall and water shortage were the foremost challenges experienced by the population. Historic data showed an annual decrease in precipitation and increase in temperature. Precipitation shift and a low R-squared values (0.04 - 0.47) for precipitation indicated climatic variation. Decrease precipitation (gradient -11.84) coincided with the periods of droughts (1993 - 2019) given by the negative values of SPI (up to -3). The hydrological changes realised were 23 springs and 13 streams dry off and 27 springs and 16 streams have become seasonal. Projected data showed increase in precipitation and temperature, leaving Bamenda with the challenge of poor water quality that negatively affects public health and development. This study highlights the need to adopt current water and drought management practice in this area.

The Impact

There is increasing evidence that global climate variability and change is affecting the quality and availability of water supplies. Integrated water resources development, use, and management strategies, represent an effective approach to achieve sustainable development of water resources in a changing environment with competing demands. It is also a key to achieving the Millennium Development Goals. It is critical that integrated water management strategies must incorporate the impacts of climate variability and change to reduce vulnerability of the poor, strengthen sustainable livelihoods and support national sustainable development. UNDP's strategy focuses on developing adaptation in the water governance sector as an entry point within the framework of poverty reduction and national sustainable development. This strategy aims to strengthen the capacity of governments and civil society organizations to have access to early warning systems, ability to assess the impact of climate variability and change on integrated water resources management, and developing adaptation intervention through hands-on learning by undertaking pilot activities.

Climate Vulnerability

Increasing climate variability and change coupled with steady population growth is threatening water resources and livelihoods of communities living in the Wami-Ruvu and Rufiji basins in Tanzania. These basins are host to three large urban centers, namely Dar es Salaam, Dodoma and Morogoro, with a combined total of more than 7 million people. Increased demand for ecosystem services from the available surface water resources and a decreasing supply of clean and safe water are exacerbating the vulnerability of communities in these basins. Several studies have analyzed climate projects in the two basins but little attention has been paid to identify locations that have vulnerable communities in a spatially-explicit form. To address this gap, we worked with stakeholders from national and local government agencies, basin water boards and the Water Resources Integration Development Initiative (WARIDI) project funded by USAID to map the vulnerability of communities to climate variability and change in the two basins. A generalized methodology for mapping social vulnerability to climate change was used to integrate biophysical and socioeconomic indicators of exposure, sensitivity and adaptive capacity and produced climate vulnerability index maps. Our analysis identified vulnerability “hotspots” where communities are at a greater risk from climate stressors. The results from this study were used to identify priority sites and adaptation measures for the implementation of resilience building interventions and to train local government agencies and communities on climate change adaptation measures in the two basins.
