8 Cumulative Impacts of Climate Change Variability …

Reservoirs are established to provide critical services; they represent a large financial
legacy from previous generations. With often limited locations appropriate to site new
reservoirs, it is imperative that current reservoirs are analyzed and studied to improve
and enhance their overall sustainable management.
In Nigeria, there are many dams that have been built and utilized for various
purposes, particularly in semi-arid northern Nigeria. These dams are vital resources
because they enhance the socioeconomic life of the people in areas where they are
established.
The purpose of Goronyo Dam is to regulate flood from watershed areas in Kastina
and Zamfara, including parts of the Niger Republic. However, in exceptionally dry
years such as 2017 and 2018, there was an unanticipatedly low flow, siltation problems and little volume of rainwater, coupled with over-abstraction for irrigation
agriculture from the upstream area of the dam.
Climate change in Nigeria is now devastating and destructive: the promotion of
concerted effort and action is necessary to decelerate its impact on society.
Maintenance, including de-silting which has not been undertaken in over twenty
years, is essential in order for Goronyo residents in Sokoto State to reduce the risk
of even more water shortage challenges. To achieve this, collaboration among reservoir managers and climate scientists in Nigeria must result in the development of
simulation modeling platforms to explore and test adaptive management strategies
for altered climate patterns through careful review of available tools and thorough
consultation with resource managers.
