Africa is one the most vulnerable continents in terms of Climate Change. Climate Change financing has become a crucial tool for climate resilient economic development. It also funds adaptation and mitigation efforts. These needs can either be met through domestic revenue mobilisation or international private finance. A growing interest is being shown in regional carbon pricing efforts. The East African Alliance on Carbon Markets & Climate Finance expressed interest in such initiatives.
Sub-Saharan Africa's (SSA) is a region where climate change is especially important. The population is already at high risk of malnutrition. Its rainfed farming systems are particularly vulnerable. There is also a rising trend of rural-urban migration that contributes to the increasing urbanization trend in the area. Moreover, a large proportion of the region's population relies on ecosystem services. Despite this, SSA is the continent that produces the least greenhouse gas emissions. This is however not sufficient to address the full impacts of Climate Change on natural systems, and human livelihoods.
Climate change will impact rainfall patterns and storm severity, leading to changes on hydrological regimes and freshwater flow to estuaries. These changes may exacerbate already existing anthropogenic pressures. So adaptation and mitigation should consider the abiotic consequences of Climate Change, as well as existing anthropogenic forces. Under a warming scenario of 4 text-degrees Celsius, the SSA could see sea level rise up to 1 meter by 2100.
To help in the development of adaptation and mitigation strategies, it is important to assess the vulnerability of South African estuaries. This study highlights the most important stressors associated with Climate Change, and how they could impact estuaries.
Climate Change stressors include a rise in sea levels, decreases in rain and sea ice and shifts in wind patterns and temperatures. These changes are likely affect estuarine functions, including nutrient flows, biochemical regimens, salinity and mouth states. Estuaries are highly dynamic and vary widely from one location to the next, because of the interplay between land and sea processes. Therefore, it is necessary to resolve the vulnerability assessment spatially taking into consideration the topography and distribution of estuarine ecology and biology.
This study used statistical models, a Coordinated Regional Downscaling Experiment and statistical models to assess the future vulnerability of South Africa's estuaries. A slight increase in interannual variability could result in a decrease freshwater runoff from estuaries. However, extreme precipitation events increased in the summer for the KwaZulu Natal coast.
Many studies have been performed to assess South African estuaries' vulnerability to climate change. These studies are based on statistical models, coastal topography, and coastal abiotic drivers. However, this review requires a more thorough and consolidated overview.
In addition to providing essential habitat for coastal species, estuaries are also important feeding and nursery grounds for migrant birds. They also provide highly productive habitats for fish, shrimp and other aquatic animals.
FAQ
What is the relationship between climate change and extreme weather events?
Global warming is directly connected to extreme weather events such a heat wave, floods or droughts, cyclones storms, hurricanes, and cyclones. Atmospheric temperatures have increased due to global warming which has affected different weather phenomena on a global scale.
According to climate scientists, the frequency of extreme weather-related catastrophes has more than doubled in the past 20 years. As the ocean temperature rises, so does the frequency of extreme weather-related disasters. This impacts the normal distribution of storms or hurricanes in different areas across the globe.
2015 El Nino brought warm water towards South America. This led to increasing temperatures at an alarming pace and heavy rains that caused floods and displacement in Peru, Bolivia and other countries. Many places, including Antarctica has recorded its highest temperature ever. This is an indication of a strong correlation between global warming trends & the occurrence/frequency of extreme weather phenomena around the globe.
Another example is Hurricane Irma. In 2017, it caused $50 billion of economic losses not just in Florida, but also in other states like Puerto Rico, Cuba and Puerto Rico. This shows that climate change is responsible again for the dramatic rise in major storms.
The Intergovernmental Panel on Climate Change, (IPCC), concluded that human activities are increasing severity of climate change. This naturally leads, in turn, to more severe and intense natural disasters globally. Thus, there is strong evidence concerning humans' relationship to extreme weather events occurring around us all.
How can the world make a transition to a more sustainable future given the challenges presented by climate change?
Sustainability refers to the ability to satisfy current needs while not compromising future generations' ability to do so. An urgent need exists to act to eliminate our dependency on finite natural resources and to shift towards a more sustainable method of using them.
In order to create a more sustainable world, we must change our consumption patterns and production methods. We also need to consider our dependence on natural resources, such as fossil fuels. We need to find new technologies, renewable energy sources, and systems that can reduce harmful emissions and still meet our daily needs.
In addition, it is essential that we adopt an integrated approach when looking at sustainability. This means taking into account all aspects of production, from the materials used, waste management, and reuse strategies, to energy utilization in transportation and industry. There are many potential solutions available including the utilization renewable energies like sun, wind, and water power; improved waste management systems; higher efficiency in agriculture; improved transport network; green building regulations; sustainable urban planning initiatives.
This goal requires behavioral changes from individuals in all sectors of society. Education programs are essential to assist people in understanding the impacts of climate change. They can also help them understand how they can contribute positively to a more sustainable planet through micro-actions like reducing food waste and adopting low-carbon lifestyles.
Collaboration between government leaders, industry leaders, as well as citizens is the only way to make significant progress toward creating a more sustainable future for our children.
What impact does politics have on global efforts to tackle climate change?
Climate change is a controversial issue that has caused a lot of division between nations, governments and individuals. The political positions of various actors have an effect on the implementation and effectiveness of measures to combat climate change. It is becoming difficult to reach consensus on global efforts for addressing this urgent environmental crisis.
Most scientists agree that humans are causing climate change. This is why it is urgent to act. The politics surrounding these issues often undermines global cooperation which is needed to make effective progress in implementing sustainable energy practices, upholding regulations protecting natural habitats, researching viable technological solutions, and other climate change interventions.
Many governments across the globe are determined to protect their own economic interests and enforce regulations that restrict business activities. This frequently clashes with the regulations that experts recommend in order to tackle climate change effectively. Without strong commitments of all participating countries, and international action on a large scale, it becomes difficult for any state or group or states to effectively address climate-change legislation.
Different power dynamics can make it difficult to achieve full consensus on the best ways to address climate change. Countries with more economic power frequently appoint their own representatives for international negotiations over the environment. This can lead lopsided discussions between countries' perceived interests and those of all other parties. A number of potential side effects that could be caused by radical changes like geoengineering were also discussed at national and international levels.
Also at the grassroots level, grassroots movements have fought against powerful opponents such as corporate ownerships. These lobbies are trying to preserve politically favorable positions for their industry especially when it is about funding research into alternative sources of energy production or enforcing Renewable Energy Technology mandates. If individual governments want to make valid progress in the subject matter themselves instead of seeking short-term benefits or spectacles, they must be clearheaded about possible outcomes.
To mitigate the current environmental crisis, it will be crucial that resources are properly distributed and political divisions between countries are not overlooked.
