The climate change, prolonged droughts and invasive vegetation are increasing the intensity and difficulty of controlling wildfires.
What are the Major Factors Increasing Wildfire Risks?
- Climate change – Rising temperatures, low humidity and strong winds create favourable conditions for rapidly spreading and intense wildfires.
- Prolonged droughts – Dry vegetation increases fuel availability, while water scarcity limits firefighting capacity.
- Invasive alien vegetation – Woody species such as acacia, pine, eucalyptus and hakea accumulate combustible biomass, increasing fire intensity and severity.
- Changing land use – Forestry plantations, dry agricultural fields and settlements near fire-prone landscapes increase exposure to wildfire risks.
- Human activities – Arson, escaped controlled burns and unattended cooking or warming fires are major causes of unwanted wildfires. Lightning can also trigger fires.
- El Nino – The developing 2026 El Nino may cause hotter and drier conditions in parts of southern Africa, potentially increasing wildfire risks.
What are the Impacts of Increasing Wildfires?
- Loss of lives and livelihoods – Wildfires destroy homes, agricultural land, grazing areas and infrastructure, affecting vulnerable communities and local economies.
- Ecological degradation – They damage forests, biodiversity and natural ecosystems.
- Economic losses – Damage to timber, crops and infrastructure affects employment and increases recovery costs.
- Firefighting challenges – Extreme heat, dryness and changing wind conditions make firefighting operations more dangerous and expensive.
What are the Major Challenges in Wildfire Management?
- Increasing fire intensity – The number of fires alone does not indicate their severity; their size, intensity and difficulty of containment are equally important.
- Invasive vegetation management – Accumulation of combustible biomass increases fire severity, as demonstrated by the 2017 Knysna fires in South Africa.
- Human–wildlife landscape interface – Expanding settlements and infrastructure near fire-prone areas increase human exposure and potential damage.
- Institutional limitations – Limited resources, uneven implementation of fire-management measures and unclear responsibilities weaken preparedness.
- Ecological considerations – Grasslands, fynbos and savannas depend on periodic natural burning, making it necessary to distinguish beneficial ecological fires from destructive wildfires.
What Measures are Needed for Effective Wildfire Management?
- Early warning systems – Strengthen weather forecasting and satellite-based monitoring to identify high-risk areas and provide timely warnings.
- Preventive vegetation management – Control invasive alien species and reduce the accumulation of combustible vegetation.
- Community participation – Involve local communities in identifying fire causes, preparing village-level fire-management plans and implementing preventive measures.
- Capacity building – Provide firefighting training, affordable equipment and awareness programmes to vulnerable communities.
- Scientific research – Use satellite data and research to understand fire behaviour and develop region-specific management strategies.
- Institutional coordination – Strengthen coordination among forest departments, local authorities, communities and other stakeholders.
- Example – A fire-management project in Tanzania's Southern Highlands used satellite data to identify wildfire-prone areas.
- They involved villagers in developing local fire-management bylaws, training programmes and village-specific plans.
What lies ahead?
- Wildfire management must shift from reactive firefighting towards climate-informed prevention, ecosystem management, early warnings and community-based preparedness.
- The objective should be to maintain ecologically beneficial fires while preventing uncontrolled wildfires that threaten lives, livelihoods and biodiversity.
