Climate change threatens Africa’s transportation system: what to do

Transportation infrastructure, such as road and rail systems, is one of the areas most threatened by climate change.Extreme weather such as floods, rising sea levels, and storm surgesrepetition It causes havoc in the transportation network.


In Africa, extreme weather is a threat that can cause massive structural damage. It can also accelerate the aging of infrastructure components.This is pretty Economic loss..

For example Recent reports In Tanzania, vulnerabilities in the country’s transportation system have been revealed. Long sections of roads and rail networks are exposed to extreme floods, which will have greater impact in the future.

The report estimates the worst-case confusion in Tanzania’s multi-modal. Transport network You can lose up to $ 1.4 million per day. In addition, damage to these networks can disrupt the flow of goods and people and reduce economic productivity.

This suggests that governments need to develop transportation infrastructure capable of coping with current and future climate change.

Fortunately,”climate-The proven “transportation infrastructure already exists within the government’s planning body. Recent worksInvestigated standard gauge rails business In Tanzania Climate change Adaptability can be incorporated into environmental impacts Evaluation procedure.

Environmental impact assessment is a widely used environmental protection measure. It is used by governments, donors and lenders to approve new development projects and significant extensions to existing projects. This process can be used to identify climate risks and minimize them through environmentally friendly project design.

Transport infrastructure is essential for developing countries, as efficient and reliable transport networks are essential for domestic and international trade. We hope that our findings will provide useful lessons for policy makers, planners and developers as the climate changes.

Risk check

Environmental impact assessment is an important process for positively and negatively identifying, predicting, and assessing the potential environmental impacts of proposed development actions. These are the risks to the project and the risks to the natural environment of the project.

The evaluation is intended to be made before major decisions are made and commitments are made. Both private and public sector agencies often ask registered environmental experts to conduct the survey.

Almost every country has some form of law that requires an environmental impact assessment. These are performed on specific development projects, especially those that can have a significant impact on the environment. This often involves major transportation infrastructure.

The investigation culminates in a series of observations and recommendations that regulators and developers are expected to participate in. The law usually provides for follow-up as to whether they were there. In countries with strong institutional frameworks, violators often face fines, suspensions and even imprisonment.

Since the evaluation needs to be performed on a major project, it provides an efficient and direct way to include adaptations.

Railway in Tanzania

this is what up Standard gauge railway in Tanzania.

The railway, which is a $ 14.2 billion investment by the Tanzanian government, is currently under construction.Is part of “Central Corridor” It connects Tanzania, Uganda, Rwanda and the Democratic Republic of the Congo. It also provides access to the Indian Ocean. The government has signed a contract with the Turkish company Yapi Merkezi to design and build the first phase of the project, crossing about 541 km. Started activities in 2017.

Because it is vulnerable to climate change —I’m particularly concerned about Massive Floods and Landslides — Environmental Impact Assessment sought to prepare the project for potential climate risks.

The evaluation was conducted by an interdisciplinary team under an international consulting firm. Environmental resource managementThey performed climate forecasts along the proposed route and outlined adaptation measures to the predicted risks.

Recommendations include the use of heat-resistant asphalt, the installation of flood barriers, and the use of rebar. They also proposed a monitoring plan outlining key monitoring aspects, indicators, responsible persons, and timing.

Tanzania’s Environmental Impact Assessment Act and regulations do not explicitly address climate change issues. The move to carry out the assessment was the result of pressure from international climate-sensitive lenders. It is not yet known if the recommendations will be implemented during construction and throughout subsequent project phases.

Our research shows great potential for environmental impact assessments to facilitate adaptation in transportation projects. That makes sense.Most african countries Insufficient resources required Invest in an independent adaptation project.

Obstacles to remove

Adapting to climate change Environmental impact assessment It’s a simple step, but it hasn’t been done.

This is due to several challenges, including lack of knowledge, awareness, technical and financial resources, and legislative support. For example, Tanzania’s laws and regulations do not specifically require this practice.

Moreover, developers rarely go beyond what is required by law. Due to factors such as cost and time constraints, they naturally consider such requirements unwelcome. The additional project approval process can lead to developer delays and increased costs.

Weathering project

There are several steps you need to take to ensure that your project is “weather resistant” in the future.

First, laws and regulations need to be formalized so that climate change is included in the assessment process. These must be supported by technical guidelines and strategic planning.

Second, it requires considerable investment in capacity building and awareness raising at the organizational level. In addition, climate data must be available and communication between climate scientists and assessment practitioners needs to be strengthened.

Finally, our treatise leverages its influence on adaptation aid providers, development partners, and international lenders such as the World Bank, African Development Bank, and the IMF, through financing procedures and more. I’m looking for. This will put pressure on the planning process to include climate change scenarios.
