Calls for Scientific Action to Climate Change in Africa

The escalating complexities of climate change demand urgent attention and concerted efforts from scientific contributors worldwide. As unprecedented occurrences of extreme weather events intensify, the imperative for action becomes ever more pressing hence an emphasis on the role played by the Intergovernmental Panel on Climate Change (IPCC). From debilitating heat waves gripping African nations to critical water shortages in South Africa and escalating food insecurity across the continent, the need for decisive action is undeniable.

Embracing the Sustainable Development Goals (SDGs) has been pointed out as paramount in tackling these pressing issues both within Africa and globally. With up to 62% of the population reliant on agriculture for employment, the sector faces unprecedented challenges exacerbated by climate change-induced disruptions that have stirred increased famine and hunger issues.

Compounding this challenge is the fact that 66% of the sub-Saharan workforce operates in informal sectors, rendering adaptation strategies more complex in a region where youth comprise a significant portion of the population. The pervasive impacts of climate change manifest in various facets of life, from heightened health risks such as increased malaria incidence to widespread water scarcity, ecosystem degradation, economic instability, and food insecurity.

Agriculture, a cornerstone of Africa’s economy and vital for food security, according to scientific data from IPCC, the sector has witnessed a 32% reduction in productivity since 1961, largely attributed to climate change-induced factors. The calls to further address food insecurity amplify the role of small-scale farmers in the production cycle solving malnutrition, famine, and hunger disasters.

The global community’s efforts to meet the Paris Agreement’s ambitious temperature threshold of 1.5°C are severely challenged by the escalating impacts of climate change. With the livelihoods of humans, biodiversity, and wildlife increasingly under threat, urgent and decisive action is imperative to prevent irreversible climate extremes.

An illustration of using science to respond to climate crisis

Debra Roberts, one of the six co-chairs of the Intergovernmental Panel on Climate Change and co-chair of Working Group II for the sixth assessment in 2015, underscores the critical link between climate conditions and migration, with millions displaced by weather-related disasters in Sub-Saharan Africa in recent years, exacerbating rural-urban migration patterns. She emphasizes the urgent need to align policies with scientific warnings, transition to renewable energy sources, implement climate-smart agricultural practices, and foster collective action.

The UN’s Adaptation Gap report underscores the inadequacy of current adaptation efforts, particularly concerning the most vulnerable communities. While adaptation remains crucial in building resilience, there is a glaring disparity between the resources allocated and the magnitude of risks faced.

Addressing this disparity requires a concerted effort to bolster adaptation financing, bridge existing data gaps, enhance public awareness through capacity-building initiatives, and develop robust response mechanisms to mitigate maladaptation risks, ensuring the protection of vulnerable populations.

In conclusion, the scientific consensus is clear: urgent and decisive action is needed to address the escalating impacts of climate change in Africa and beyond. Embracing sustainable development goals, prioritizing adaptation efforts, and fostering international cooperation is imperative to mitigate the profound socio-economic and environmental challenges posed by climate change
