Building Climate Resilience: Understanding Awareness and Adaptation in Flood-Prone Communities

This study looks at how people in flood-prone areas of Nueva Ecija, the Philippines, understand and respond to climate change. It explores their awareness, attitudes, risks, and actions to adapt to and reduce the effects of climate change. The study also examines how education, income, and location affect the way people prepare for climate risks (Çıplak, 2022, paywall). Around the world, climate-related disasters are increasing, and poorer areas are often hit the hardest (Fawzy et al., 2020, open access).

To gather information, researchers used surveys, informal interviews, and observations with 900 households. The results show that most people have a moderate understanding of climate change. However, families in rural areas take more action to adapt and protect themselves because they feel more at risk. Based on these findings, the study suggests Project LEARN, a program to teach communities more about climate change and help them become stronger against its effects. This research helps local communities understand climate change better and provides ideas to improve how they adapt and reduce risks in areas most affected by it (Fawzy et al., 2020, open access).

Why are rural communities are more likely to take action on climate than are urban ones?

The article explains that rural communities are more likely to take action on climate change adaptation and mitigation than urban ones due to several key factors:

  1. Greater Perceived Risk and Vulnerability

    • Rural households perceive themselves as more vulnerable to climate risks, particularly regarding health, access to goods and services, and overall well-being.
    • They rely more on natural resources and are more exposed to climate-induced disasters like floods, making them feel a stronger need to adapt.
  2. Stronger Engagement in Adaptation and Mitigation Strategies

    • Because of their heightened sense of risk, rural respondents reported more frequent adaptation and mitigation behaviors than urban respondents.
    • Actions such as building flood defenses, conserving energy, and improving household emergency plans were more common in rural areas.
  3. Limited Access to Services and Resources

    • Unlike urban populations, who may have more government or institutional support, rural communities often have fewer safety nets and thus take proactive measures to protect themselves.
    • This self-reliance drives them to implement climate adaptation strategies more consistently.
  4. Economic and Occupational Differences

    • Rural communities depend more on agriculture, which is highly sensitive to climate variability (e.g., floods, droughts, erratic weather).
    • The direct impact on their livelihoods makes them more aware of climate risks and more motivated to take action compared to urban dwellers, whose jobs may be less affected.
  5. Household and Socio-Demographic Influences

    • Larger households in rural areas tend to engage more frequently in climate adaptation and mitigation efforts.
    • Education and income levels also play a role—households with lower income and education often perceive higher risks and act accordingly.

In short, rural communities take more climate action because they feel more vulnerable, have fewer external resources, and depend on climate-sensitive livelihoods like farming. Their higher perceived risks and direct exposure to climate change impacts drive more frequent adaptation and mitigation responses compared to urban communities.

Is education level is a negative indicator for taking climate action?

Education level is not a negative indicator for taking climate action, but its relationship with climate adaptation and mitigation is complex. The article suggests that higher education is correlated with greater climate awareness, but not necessarily with higher adaptation and mitigation action. Here’s why:

Key Findings on Education and Climate Action:

  1. Education Increases Awareness but Doesn't Always Lead to Action

    • The study found that higher educational attainment strongly influences climate change perceptions—people with more education tend to have a better understanding of climate change concepts (e.g., causes, impacts, and risks).
    • However, this doesn’t always translate into more frequent adaptation or mitigation behaviors.
  2. Rural Communities with Lower Education Take More Climate Action

    • Rural respondents, who generally have lower education levels, tend to perceive higher climate risks and engage more actively in adaptation and mitigation.
    • This is likely because they experience more direct climate impacts (e.g., crop losses, floods, health risks) and have fewer external safety nets, making adaptation a necessity rather than a choice.
  3. Urban Communities with Higher Education Show Less Urgency in Adaptation

    • Urban respondents, who generally have higher levels of education, perceive lower risks and engage less frequently in adaptation and mitigation strategies.
    • This could be because they rely more on government support, infrastructure, or services, reducing the perceived need for individual action.
  4. Income Plays a Role Alongside Education

    • Higher-income individuals (who often have more education) may have more resources but may not feel as vulnerable, leading to lower adaptation effort compared to lower-income households that must take action to survive.
    • Economic stability allows for passive adaptation (e.g., moving to safer areas, relying on technology), while lower-income households must actively adapt (e.g., building flood barriers, altering agricultural practices).

Overall, education helps people understand climate change, but does not always lead to more climate action—especially if they do not perceive immediate risks. Rural communities with lower education levels take more action because they feel more exposed and lack alternative support systems. However, this doesn’t mean education is a negative factor—rather, it highlights that perceived vulnerability is a stronger driver of climate action than education alone.

Super Typhoons and the Human Cost of Climate Change in the Philippines

The Philippines is facing stronger and more frequent typhoons, driven by warming oceans, making this the country’s most urgent climate challenge. These intensified storms not only destroy homes and communities but also tear families apart—forcing millions to evacuate, rebuild, or even relocate entirely. The effects are deeply personal: parents struggle to keep their children safe, provide food, and find secure shelter, while livelihoods are often wiped out in an instant. The economic impact is immense, with projections suggesting the country could lose over 13% of its economy by 2040. These storms also worsen food shortages, spread diseases like dengue and cholera, and threaten the safety of millions, especially those living in coastal areas. The growing intensity of typhoons highlights how climate change is making life increasingly difficult for Filipino families each year.

Climate Risk Profiles - Jamaica and the Philippines

New, Climate Risk Profiles for Jamaica and the Phillipines

Navigating Climate Risks: A Comparative Insight into Jamaica and the Philippines

Climate change presents an existential threat to vulnerable nations, with Jamaica and the Philippines standing out as critical examples. Both nations grapple with escalating climate impacts, yet their experiences offer unique lessons for adaptation and resilience.

The Philippines: A Storm-Filled Horizon

With over 7,600 islands, the Philippines is a frontline state for climate-induced disasters. Averaging 20 typhoons annually, the archipelago faces mounting challenges from rising sea levels, intensified flooding, and landslides. Recent decades have seen some of the strongest storms on record, such as Super Typhoon Haiyan (2013) and Rai (2021), displacing millions and causing substantial economic loss.

Urbanization adds complexity, with 70% of urban residents at risk due to rising seas. Informal settlements, often concentrated in flood-prone areas, amplify vulnerabilities. Meanwhile, agriculture, health, and infrastructure sectors struggle under climate stressors like erratic rainfall and extreme heat. Yet, the Philippines actively pursues solutions: its National Adaptation Plan and disaster management laws exemplify structured resilience planning.

Jamaica: Struggling Against the Tide

In the Caribbean, Jamaica’s climate challenges stem from rising temperatures, stronger hurricanes, and coastal erosion. Over half its population lives within two kilometers of the coast, underscoring exposure to sea-level rise and storm surges. With 90% of GDP tied to tourism and coastal industries, climate impacts are as economic as they are environmental.

Jamaica’s food and water security face heightened risks. Extreme weather disrupts agriculture and water supply, while saltwater intrusion and erratic rainfall patterns jeopardize freshwater resources. Compounding these issues are threats to coral reefs and mangroves—key natural buffers against storms and sources of economic and ecological vitality.

Shared Challenges, Unique Pathways

Both nations illuminate the intersection of climate stressors and socio-economic vulnerabilities. Women, children, and Indigenous communities bear the brunt of climate impacts, yet their inclusion in adaptation efforts unlocks pathways for innovation. In Jamaica, for example, women-led initiatives and Maroon communities emphasize local resilience strategies. Similarly, in the Philippines, integrating traditional knowledge into modern adaptation plans enhances community engagement.

However, solutions require significant international collaboration and financing. Jamaica has leveraged funds from the Green Climate Fund and others to bolster infrastructure and renewable energy. The Philippines, with its extensive donor support, has implemented multi-hazard warning systems and urban adaptation programs.

The Road Ahead

As nations on the climate frontline, Jamaica and the Philippines exemplify both the urgency and potential of climate adaptation. Their stories reinforce a critical truth: while vulnerabilities are local, solutions demand global solidarity. Building resilience isn’t just a necessity for these nations—it’s a blueprint for a sustainable future.

The Value of Listening and Responding to the Needs and Concerns of Community Members

It is important to listen to the needs and concerns of community members in order to understand their priorities and to develop programs and projects that are responsive to their needs. Community members are the experts on their own lives and communities, and they should be involved in all aspects of the development process, from needs assessment to implementation. By listening to community members, we can ensure that our programs and projects are effective and sustainable.


Building on existing strengths and assets within the community

Every community has its own strengths and assets. These can include natural resources, human resources, social capital, and cultural assets. It is important to build on these strengths and assets to develop sustainable and resilient communities. By building on existing strengths, we can reduce the need for external assistance and ensure that communities are able to meet their own needs in the long term.

Providing opportunities for community members to participate in decision-making and planning processes

Community members should be involved in all aspects of the development process, from needs assessment to implementation. This is because they are the experts on their own lives and communities, and they have the most to gain from successful development initiatives. By providing opportunities for community participation, we can ensure that development initiatives are responsive to the needs of the community and that they are sustainable in the long term.

Supporting capacity-building and skill-development within the community for climate resilience

Climate change is a major threat to development, and it is important to support communities in building their capacity to adapt to climate change. This can be done by providing training in climate-resilient agriculture, water management, and disaster risk reduction. It is also important to support the development of community-based organizations that can advocate for climate change adaptation and mitigation.

By listening to the needs and concerns of community members, building on existing strengths and assets, providing opportunities for community participation, and supporting capacity-building and skill-development, we can help communities to become more resilient to climate change and to achieve sustainable development.

The Future of Earth - By Fire


Will it be by fire or by ice that Earth will meet its end? Well it all depends on how you define "end". It has been known for quite some time that eventually the Earth will be swallowed by an expanding sun when the sun reaches its final stages of life as a red giant. This stage will begin sometime between 5 and 7 billion years from now - here is a nice video giving some great visualizations of what we think will happen. But a recent article in the Journal of Geophysical Research - Atmosphere tells us that we'll have our last best day far sooner. 

The sun is getting brighter (see footnote 1). One of the early challenges for paleoclimatologists (people who study the climates of yesteryear) was understanding the evolution of sun like stars and its impact on climate early in life's history on Earth. In a recent article in the journal JGR-Atmospheres authors Wolf and Toon found that increasing solar luminosity will make the Earth uninhabitable in about 2 billion years (time to start planning folks!). The good news is that though life won't be able to survive, the planet is unlikely to experience a runaway greenhouse effect as may have been the case of Venus.

Somewhat more seriously it is not that clear in my skimming the article (apologies if it is covered - time constraints) if surface albedo might influence the evolution of Earth's climate under a brightening sun. Here is where we find the theories of James Lovelock and the Gaia Hypothesis.

Solar luminosity is increasing on long time scales, as our sun is at an early stage of solar evolution, "burning" hydrogen, forming helium by nuclear fusion, slowly getting brighter. The sun's brightness increased steadily through the Cenozoic, by about 0.4 percent according to solar
physics models (Sackmann et al., 1993). 


Urban Climate

A recent journal article by MZ Jacobson et al points out some of the climatological impacts of urbanization on local climate. The land use change that urbanization leads to is known to impact climatological conditions through changes in soil moisture evaporation, transpiration (evaporation from plants), heat absorption and advection (wind).

In this article the authors used models to study the impact of the change in urban extent in Beijing. Beijing provides a good case due to the extreme nature of changes there - the urban extent of the city quadrupled between 2000 and 2009.

Key Points from the article:

  • Beijing's expansion created a ring of impact in the new portion of the city
  • Without considering the impact of more vehicles and other sources of human caused polution - urbanization's impact on climatological conditions alone slowed winds and increased pollution vertical dilution and increased ground level temperature, and ozone

Interestingly the authors used crowdsourced data on road surface area in their study.

Take homes:
This study found that urbanization changes local climate in these ways - it:

  • increases ground level temperature
  • decreases ground level humidity
  • decreases horizontal movement of air (wind, advection)
  • increases vertical movement of air (convection)
  • reduces reflectivity of the surface (albedo) causing the retention of more solar energy
These impacts:

  • decreased surface pollution by promoting vertical mixing
  • but increased surface ozone (O3) due to other changes in the chemical profile of the air
None of these impacts takes into account vehicle use or other pollution sources.

Resilience - what it is, and what it could be.

What is resilience and how do you put that into practice? Here are links to three publications that speak to resilience in the context of addressing climate change in cities and what it means in terms of planning and implementation. Resilience is not just "getting back on one's feet and returning to what you had before" but rather an opportunity for fundamental change - or to use the current buss phrase, an opportunity for transformation.

The term resilience is increasingly applied in thinking through how to deal with climate change. On one level it can be applied as a way of bridging the historic al divide that has existed between climate mitigation and climate adaptation. Climate resilience refers to both actions that reduce climate impacts as well as actions to respond to climate impacts. Resilience can be seen as a process of learning and innovation—we can always be more resilient. 

There are different definitions of resilience in various disciplines. Reviewing the way s in which the term resilience has been defined is useful for understanding the challenge of dealing with climate change. 

Importantly both of the definitions provided on the facing page emphasize the capabilities to learn and anticipate, as well as to respond to change. 





Abstract

Climate change will have unavoidable impacts on urban systems and populations, especially in Asia where many large cities are exposed. Climate adaptation will be essential, and planning for adaptation can be simplified through operationalizing concepts of climate resilience and vulnerability. This article reviews concepts and theories in a range of diverse fields to illustrate how the general notion of urban climate resilience can be developed into an operational framework for planning practitioners. The framework integrates theoretical and empirical knowledge of the factors contributing to resilience with processes for translating those concepts into practice. The framework includes characteristics of urban systems, the agents (people and organizations) that depend on and manage those systems, institutions that link systems and agents, and patterns of exposure to climate change. It operationalizes these concepts through structured and iterative shared learning approaches that allow local planners to define these factors in their own context, in order to develop practical strategies for local action. The viability of the framework is demonstrated through examples from resilience planning activities undertaken in 10 cities across Asia through the Asian Cities Climate Change Resilience Network funded by the Rockefeller Foundation.
