Nature-Based Solutions to Combat Storms and Heatwaves

Nature-based solutions give landholders powerful ways to prepare for storms and heatwaves by using natural ecosystems to reduce their impact. By working with natural systems, these solutions not only help lessen the effects of extreme weather but also boost biodiversity and make the land more resilient.

Increase in Extreme weather and the role of Climate Change

Climate change, driven by human activities, is leading to more frequent and severe extreme weather events. According to The Intergovernmental Panel on Climate Change, (an intergovernmental body of the United Nations), an increase of a 1.1-degree has impacted us through the increased frequency and magnitude of extreme weather events from heatwaves, droughts, flooding, winter storms, cyclones and bushfires.

Extreme weather in Australia refers to unusual and severe weather conditions that are much more intense than the typical weather for the region and time of year. This can include intense thunderstorms, cyclones, bushfires, heatwaves, droughts, floods, and severe cold spells. These events often come with strong winds, heavy rainfall, high temperatures, or rapid temperature drops, causing significant impacts on the environment, people’s health, and infrastructure. Climate change is believed to be making these extreme weather events more frequent and intense.

Problems/Impacts caused by Storms and Extreme Weather 

Climate change and the resulting extreme weather poses significant challenges to Landcare activities in NSW. These challenges arise due to the increased frequency and intensity of storms and heatwaves, which impact various aspects of land management and restoration. Here are some detailed challenges:

Soil Erosion and Degradation

• Storms: Heavy rainfall and strong winds from storms can cause significant soil erosion, washing away nutrient-rich topsoil and degrading land quality.
• Heatwaves: Prolonged heatwaves dry out soil, reducing its moisture content and making it more prone to erosion. Dry, cracked soil also loses its ability to support plant growth effectively.

Water Management Issues

• Flooding: Intense storms can lead to flooding. Floodwaters can erode riverbanks, spread pollutants, and disrupt the natural hydrology of the area.
• Drought and Scarcity: Heatwaves increase evaporation rates and water demand, leading to water scarcity. Managing limited water resources becomes a critical challenge, affecting irrigation and the health of natural ecosystems.

Vegetation Damage and Loss

• Wind Damage: Strong winds during storms can uproot trees, damage plants, and destroy newly planted vegetation. This setback requires significant replanting and restoration efforts.
• Heat Stress: Extreme heat can cause heat stress in plants, leading to reduced growth, increased susceptibility to pests and diseases, and higher mortality rates. Heatwaves can also exacerbate the effects of drought.

Risk Assessment and Planning

It is essential to identify high-risk areas and develop thorough plans for mitigating risks when preparing for extreme weather events on your property.
