Risk 6 of 10 · Climate
Climate Change and Climate Resilience Failure
Extreme weather events, droughts in Sub-Saharan Africa and broader impacts of climate change and climate action failure, alongside inadequate adaptation and context relevant climate resilience.
Definition
Extreme weather events, droughts in Sub-Saharan Africa and broader impacts of climate change and climate action failure, alongside inadequate adaptation and context relevant climate resilience.
Opportunity
Invest in climate adaptation, green technologies, and sustainable practices that drive resilience and new economic sectors.
Why this risk matters
- Climate shocks are no longer environmental issues alone; they directly affect water, food, health, infrastructure and migration pressures.
- Weak adaptation increases losses, insurance pressure and the risk of repeated humanitarian and fiscal strain.
- Climate risk compounds existing inequality and exposes gaps in long-term planning and resilience investment.
Storyline
Southern Africa faces a mounting systemic risks from climate change and a failure of climate resilience as rising temperatures, shifting rainfall patterns and more frequent extreme‑weather events intersect with existing vulnerabilities in infrastructure, settlements and livelihoods. The country is already experiencing hotter and, in many areas, drier conditions, alongside more intense storms, floods and droughts which are placing growing pressure on water systems, agriculture, human health and urban infrastructure. Yet investment in adaptation and resilience remains inadequate and fragmented, and climate‑risk considerations are still not consistently integrated into spatial planning, infrastructure design, budgeting or enterprise risk management.
These dynamics are driving increasing damage to infrastructure, agriculture and settlements, with associated water and food insecurity, health impacts from heat stress and disease, and rising insurance claims and premiums, including the emerging risk of assets or regions becoming effectively uninsurable. At the same time, Southern Africa’s slow and contested energy transition, and its continued dependence on carbon‑intensive sectors, expose the economy and financial system to transition risks such as stranded assets, shifting trade patterns and tightening climate‑related regulation.
The combined effect is to raise fiscal and humanitarian burdens, intensify migration and displacement pressures, and erode social cohesion and investor confidence, creating a feedback loop in which climate impacts, inequality and weak capacity reinforce one another.
At a glance: Why this risk matters

Weak adaptation increases losses, insurance pressure and the risk of repeated humanitarian and fiscal strain.
Climate risk compounds existing inequality and exposes gaps in long-term planning and resilience investment.
Scenario outlook
| Time horizon | Best Case | Medium Case | Worst Case |
|---|---|---|---|
| Short-term (1-2 years) | Successful climate adaptation initiatives launched, green economy investments attract funding. Moderate weather patterns with manageable extreme events. | Localised extreme weather events cause disruption, adaptation efforts are delayed, and some green investments proceed but on an insufficient scale. | Severe droughts and flooding devastate agriculture, leading to mass displacement, damage to critical infrastructure, and a food security crisis. |
| Medium-term (3-5 years) | Climate resilient infrastructure operational, renewable energy transition accelerated, adaptation strategies embedded in planning, and regional cooperation strengthened. | Incremental adaptation progress, continued vulnerability to extreme events, uneven implementation across sectors, and rising adaptation costs. | Cascading climate disasters, agricultural collapse, water system failures, and climate migration are overwhelming urban capacity. |
| Long-term (6-10 years) | Southern Africa becomes a climate resilient economy, net zero pathways are established, a just transition creates green jobs, and international climate finance is secured. | Persistent climate vulnerability, reactive rather than proactive responses, widening adaptation gap, and economic drag from climate impacts. | Climate catastrophe renders regions uninhabitable, economic collapse from compounding climate shocks, social breakdown, and a failed state scenario. |

International view
Climate change and climate resilience failure
Climate change is recognised as a direct threat to continuity and economic stability, manifesting through floods, droughts, storms, wildfires, heat stress and associated food and water security issues. Historical data is less reliable as a predictor of future events, increasing the importance of scenario analysis and adaptive resilience planning.
