Lake Chad: Assessing Current Management Strategies.

To be truly effective, water management should be conducted considering the basin as a whole. Changes made in one part of the system will have huge impacts on the immediate upstream and downstream areas, but effects will be felt basin-wide. However, it is so often the case, and Lake Chad is no exception, that a river basin is divided amongst different authorities and management decisions are not made holistically.

In an effort to tackle this and make water management decisions for Lake Chad on a regional scale, the Lake Chad Basin Commission (LCBC) was formed in 1964, joining together the states of Nigeria, Niger, Cameroon, and Chad (and more recently the Central Africa Republic and Libya). Many of their past and ongoing projects have a broad focus on strengthening the resilience of the basin system but at the core of their activities is the aim to increase socio-economic security and reduce conflict for the 38 million who live in the basin. However, the LCBC is not recognised as a Regional Economic Community by the African Union and is restricted by other complex institutional frameworks, meaning its political and economic investment is limited.

Therefore, a number of global organisations have collaborated on projects to protect Lake Chad. The World Bank, the United Nations Educational, Scientific and Cultural Organisation (UNESCO), the Cooperation in International Waters in Africa (CIWA) program, and a number of other international partners workshopped with the LCBC in 2017 with a view to run a programme to consolidate and improve knowledge of the hydrological system of Lake Chad and the dynamics of water resources. This led to the development of an updated model for groundwater dynamics in the basin, a remote sensing initiative and the creation of the Lake Chad Flood and Drought Monitor, an interface that allows users to see hydrological predictions for the area. The knowledge accumulated by the project was intended to better inform stakeholders and decision-makers of the dynamics of the lake and the basin.

While this all sounds great and definitely has made improvements in terms of monitoring the lake and progressing understanding of the basin system, it takes a very top-down management approach. The Lake Chad Flood and Drought Monitor is not public domain and an increasing reliance on remote sensing means that monitoring knowledge is restricted to those specialised in sensing software.  It also does not stand to address the issue I started this post with: the holistic and regional management of Lake Chad’s resources. If utilised properly and given the proper political framework to hold its member states accountable for the collaborative and sustainable management of the lake, it could be a positive force to help adapt to the environmental changes the lake is experiencing.

Until next time!

    Hi Briony

    I was just looking at some critics of the LCBC that have claimed that the LCBC have caused communities living on the banks of the basin to have supply chains broken through vehicular bans and boat movement restrictions.

    Do you think the defence of the hydrological and ecological system should be placed higher than the socio-economic development of the societies living on the basin?

    Sorry for dropping by with a very large question, ha.

      Hi Tim,

      Great question. I think the two are extremely entangled but ultimately it's a weighing of the severity of the impacts in either case. I think that there's an opportunity for governments to step in and provide alternative supply routes and mitigate any impacts on socio-economic developments. I don't think there as many options when it comes to trying to protect the lake and therefore I supposed I would place it above the socio-economic development of the population of the basin (although ultimately they go hand in hand).

Shrinking Water Sources: Lake Chad.

Lake Chad is a classic example of the impacts of environmental change on the hydrological system in Africa and therefore an excellent place for us to begin our exploration of this topic. Lake Chad is located in the centre of the semi-arid Sahel region of West Africa, spanning areas in Niger, Nigeria, Chad, and Cameroon.   In the 1960’s it was ranked as the world’s 6 th largest inland water body , covering an area of 25,000 km 2 . By 2004, its area was just 532 km 2 , a reduction of approximately 90%. The scale of the change can be visualised in Figure 1 . The lake has huge economic importance for the area, namely for the fishing industry but also for agriculture and pastoralism. Therefore measuring the changes to the lake and identifying the parameters that influence them is vital to adaptation.

Desertification- When The Dry Gets Drier.

In one of my previous posts, I broadly described how climate change will impact Africa’s hydrological cycle by making wet areas wetter and dry areas drier. There are a considerable number of negatives to extreme aridity: drought, degradation of vegetation and overstretching of resources to name three. All three of these impacts can contribute to desertification. Desertification is a specific type of degradation that occurs in dryland areas, extending arid areas beyond their existing boundaries and changing the environment of the landscape. It includes declines in the quality of soil, vegetation, and water resources, all of which can be either temporary or permanent. These declines are drastic for human populations, globally 2.7 billion of whom live in dryland areas . There is a complex relationship between climate change, drought, and desertification , linked by a number of feedback loops and this complexity has often hindered the comprehensive monitoring of desertification proces...
