Climate change is not a distant threat, but a present reality for many people around the world. Extreme weather events, such as heatwaves, floods, droughts, and storms, are becoming more frequent and intense, posing serious challenges to human health, livelihoods, and well-being.
However, not everyone is equally affected by these impacts. Some communities, especially those with low incomes and limited resources, are more vulnerable and exposed to the risks of climate change.
Yet, these communities are not just passive victims of environmental injustice. They are also active agents of change, who have developed innovative and effective ways to cope with and adapt to the changing climate.
In this article, we will explore how low-income communities in Western Sydney, Australia, are demonstrating remarkable resilience and creativity in the face of extreme heat, and what lessons we can learn from their grassroots adaptation strategies.

Western Sydney is a region of contrasts. It is home to more than two million people, representing a rich diversity of cultures, languages, and backgrounds.
It is also a hub of economic activity, hosting major industries, businesses, and infrastructure projects. However, it is also a region of inequality, where many residents face social and economic disadvantages, such as poverty, unemployment, poor health, and low education.
These disadvantages are exacerbated by the effects of climate change, especially extreme heat. Western Sydney is one of the hottest places in Australia, with summer temperatures often exceeding 40°C.
Moreover, it is projected to experience more frequent and longer heatwaves in the future, as well as higher night-time temperatures, which reduce the chances of cooling down.
Extreme heat poses serious threats to the health and well-being of low-income communities in Western Sydney. Many residents live in poorly insulated and ventilated homes, which trap heat and create uncomfortable and unsafe indoor conditions.
Some residents also lack access to affordable and reliable cooling systems, such as air conditioners or fans, or to comfortable public spaces, such as parks, libraries, or pools, where they can seek refuge from the heat.
Furthermore, some residents have pre-existing health conditions, such as asthma, diabetes, or cardiovascular diseases, which make them more susceptible to heat stress and dehydration.
The Power of Local Knowledge: How Low-Income Communities Adapt to Extreme Heat
Despite these challenges, low-income communities in Western Sydney are not helpless or hopeless. They have developed various ways to cope with and adapt to the extreme heat, drawing on their local knowledge, social networks, and communal resources.
These grassroots adaptation strategies are often overlooked or undervalued by governments and city planners, who tend to focus on large-scale and top-down interventions, such as building more green spaces, improving public transport, or installing renewable energy sources.
However, these strategies are essential for enhancing the resilience and well-being of low-income communities, as they reflect their lived experiences, needs, and preferences.
Some of the grassroots adaptation strategies that low-income communities employ include:
Modifying their homes and behaviors to reduce heat exposure and increase comfort. For example, some residents use reflective materials, such as aluminum foil, cardboard, or white sheets, to cover their windows and walls, which can lower indoor temperatures by several degrees. Others use wet towels, ice packs, or spray bottles to cool themselves down. Some residents also change their daily routines, such as sleeping during the day and staying awake at night, or avoiding cooking or using appliances that generate heat.
Sharing information and resources with their neighbors and friends to cope with and prepare for heatwaves. For example, some residents exchange tips and advice on how to stay cool and healthy, such as drinking plenty of water, wearing light clothing, or checking the weather forecast. Others share or lend cooling devices, such as fans, air conditioners, or refrigerators, or invite each other to their homes or public spaces, where they can enjoy cooler temperatures and social support.
Collaborating with social housing providers and community organizations to improve their housing conditions and access to services. For example, some residents participate in co-design workshops, where they can voice their concerns and suggestions on how to make their homes more heat-resilient, such as installing insulation, ventilation, or shading. Others join community groups or programs, where they can access information, education, or assistance on how to deal with extreme heat, such as heat health alerts, heat action plans, or heat relief centers.
The Way Forward: How Low-Income Communities Can Inspire Climate Action
The stories of low-income communities in Western Sydney show that they are not just passive recipients of aid, but active participants in creating solutions for climate change adaptation.
Their grassroots adaptation strategies are not only practical and effective, but also sustainable and inclusive, as they rely on local knowledge, social capital, and communal values.
These strategies also demonstrate the potential and power of low-income communities to lead the way in climate resilience, and to inspire others to take action.
However, these communities cannot do it alone. They need the support and recognition of governments, city planners, and other stakeholders, who can provide them with the resources, opportunities, and platforms to enhance their adaptive capacity and well-being.
These stakeholders can also learn from the local wisdom and innovation of low-income communities, and integrate them into broader climate change mitigation and adaptation plans.
By doing so, they can create more equitable and resilient cities, where everyone can thrive in the face of climate change.
