Destructive Fishing Practices
Unlock Audio Lesson
Today we're going to explore how climate change interacts with local fishing practices. Can anyone tell me about some fishing techniques that might be harmful to the environment?
I heard that some people use dynamite to catch fish. Isn't that bad for the reefs?
Exactly! Using dynamite not only catches a lot of fish at once but also destroys coral reefs. This can have long-term impacts on marine life. Let's remember the acronym 'FISH' to think about sustainable fishing: Fish sustainably, Inspire communities, Save ecosystems, and Harvest responsibly!
What other methods are harmful?
Fine nets can also catch juvenile fish, which disrupts population growth. The idea is to protect not just fish but the whole ecosystem. Anyone want to give me an example?
Well, if we overfish, there won't be enough fish left, right?
Correct! It's not just about the fish; it's a whole chain reaction affecting the entire marine ecosystem. Let’s summarize: unsustainable fishing practices lead to environmental degradation.
Cultural Disconnect
Unlock Audio Lesson
Now, let's talk about the cultural aspects. How does the connection to a place affect fishing practices?
If the fishermen are from somewhere else, they might not care about the local folklore or the environment.
That's right! When fishermen don't have a deep connection to the land, they might disregard sustainable practices that the local communities value. Let’s use the mnemonic 'CARE': Connection to local culture, Awareness of sustainability, Responsiveness to local needs, and Engagement with local practices.
So the local people might use traditions to fish sustainably?
Exactly! Indigenous knowledge often contains wisdom about preserving biodiversity. This knowledge is vital for maintaining balance with the environment.
Spatial Scale Issues
Unlock Audio Lesson
Moving on to spatial scale issues, can anyone tell me how impacts from one region can affect another?
Like if a dam in one country affects flooding in another?
Exactly! That’s a perfect example. We can think of the impacts as interconnected. Let's remember the saying 'Think globally, act locally.' What does it mean?
It means we should consider how our actions affect others far away, even if we only focus on our own area.
Yes! There are often political and logistical challenges that make addressing these problems complex.
Temporal and Functional Challenges
Unlock Audio Lesson
Finally, let's discuss the role of recovery agencies. What do you think happens after a disaster when NGOs or government agencies come in?
They probably help build things back but might leave when the work is done?
Correct! Many organizations have short-term goals and may not stay for long-term recovery. We can use the acronym 'CARE' again to measure the effectiveness of these interventions, focusing on Commitment, Accountability, Responsiveness, and Evaluation.
So if they just leave after rebuilding houses, who helps the community adapt to changes?
Exactly! There is often a gap in follow-up care and adjustment. It's critical to ensure that support systems are sustainable.
Introduction & Overview

Spatial Challenges of Climate Change
Overview
This section examines how climate change creates spatial challenges by affecting ecosystems and human livelihoods, particularly regarding fishing practices. It delves into the adverse impacts of migrant fishermen using advanced, often destructive techniques, which threaten local marine environments.
Key Points
- Destructive Fishing Practices: Migrant fishermen employ non-sustainable methods, such as dynamite and fine nets, leading to overfishing and environmental degradation, especially of coral reefs.
- Cultural Disconnect: Migrants often lack a deep-rooted connection to the areas they fish in, disregarding local ecological knowledge and cultural beliefs. This disconnect exacerbates the ecological damage.
- Spatial Scale Issues: Climate change impacts may not correspond to local causes. For example, flooding in one region may be influenced by upstream activities in another country, illustrating the challenges of addressing climate change across different political and geographical boundaries.
- Temporal and Functional Challenges: Agencies involved in disaster recovery often lack long-term commitment to affected communities. Their interventions are typically short-term, which may not adequately address the ongoing needs and adaptations required by local populations.
The section underscores the necessity of understanding both local cultural contexts and the complex spatial interrelations of environmental impacts to effectively address the challenges posed by climate change.

But here in the present conditions one has to understand that many migrated fishermen have understood that a lot of fish available here and they started migrating to these places and they had adopted different various advanced fishing techniques.
Detailed Explanation
Migrant fishermen have moved to new areas where fish are abundant. They have begun using advanced techniques to catch fish, which are often more effective than traditional methods. However, these techniques can lead to unsustainable practices, harming the local environment.
Examples & Analogies
Imagine someone who discovers a new forest filled with fruit trees and starts using modern tools to harvest the fruits. While they can collect more than before, if they don’t take care, they might over-harvest and destroy the trees, leading to a barren forest in the long run.
Environmental Concerns of Advanced Techniques

And they are not necessarily environmentally friendly, but they might have used a dynamite, the fine nets that catch even a very small fish fry, and the pounding of the coral reefs to drive fish into the nets, all created problems of overfishing and the destruction of the environment when the fish live where the fish live and multiply.
Detailed Explanation
Migrant fishermen may use harmful methods like dynamite fishing and fine nets that capture young fish, disrupting the ecosystem and leading to overfishing. These practices can damage coral reefs, which serve as habitats for many fish species, ultimately reducing fish populations.
Examples & Analogies
It’s like using a vacuum cleaner to clean an entire garden, sucking up not only the dirt but also the small plants that help the garden grow. Over time, the garden becomes barren because the tools destroyed the very environment needed for plants to flourish.

So these advanced techniques these newcomers into these islands they started using the fine nets. [...] That is how it has an impact of one do not understand the cultural aspects and how different cultures understand their ecosystems on the environment.
Detailed Explanation
The arrival of migrant fishermen introduces fishing methods that do not align with local cultural practices. Locals, like the Tagbanwa people, have traditional beliefs and sustainable practices that help maintain their environment. When newcomers use harmful techniques, it threatens both the local ecosystem and the cultural identity of the community.
Examples & Analogies
Think of a town where everyone grows food using ancient, sustainable farming techniques. If outsiders come in and use chemicals and machinery, they might produce more food in the short term, but they could ruin the soil and water, making it difficult for locals to continue their traditional farming.
Impact of Coral Reef Damage

With this what you can see that how the coral reefs have been damaged and because of using the Dynamites and poisoned by sodium cyanide which used for bringing in live fish. [...] It's a chain process, in fact, the impact of tourism on bird’s nest production, the diminishing fish catch caused by illegal fishing techniques, and the careless attitudes of the people who do not have a long-term interest in protecting the land and sea which provide a livelihood of the Tagbanwa people.
Detailed Explanation
Coral reefs are harmed when destructive fishing methods are used, such as dynamite and harmful chemicals. This damage affects not only the fish populations but also the broader marine ecosystem and human communities that depend on these resources for their livelihoods.
Examples & Analogies
Consider a beautiful park where people picnic and play. If a group starts vandalizing the trees and flowers for fun, soon the park becomes unattractive and unusable for everyone. Similarly, harming coral reefs impacts not just fish but the entire community that relies on a healthy marine environment.

There is a spatial scale challenges when we talk about the climate change it talks about its very it talks up to much bigger scales, larger scales whereas the disaster it talks about much more to the point affected areas.
Detailed Explanation
Climate change issues can be widespread and involve larger geographic areas. However, the effects of disasters, like floods, can be localized and may even stem from causes far away. For example, an upstream dam might affect downstream regions in different countries, complicating responses to climate change.
Examples & Analogies
Think of a row of dominoes. When you push one over, it can cause a chain reaction affecting many others. However, if one domino is knocked over due to a push from another room, it complicates understanding how and why the chain reaction started, similar to how climate change effects can be felt far from their source.
Mismatch in Climate Change Responses

So there is also a mismatch between the horizontal scales and vertical scales where the sources of climate change often lie in other regions and countries then where it is affects are shown.
Detailed Explanation
There is often a disconnect between the areas causing climate change and those experiencing its effects. Politically and geographically, it can be challenging to address climate change effectively because responsibility for emissions is not confined to the areas that suffer from its physical impacts.
Examples & Analogies
Consider a factory that produces pollution in one region, contributing to climate change that causes flooding in another distant city. The people suffering from the floods may not have any way to influence the factory’s operations, highlighting the challenge of global interconnections.

Also, the temporal and functional challenges; when we talk about the temporal and functional challenges, it is also about the role of different agencies whether it is an NGO or a government sector or quasi-government which whoever are coming so especially the NGOs who are coming the agencies to do the disaster recovery projects.
Detailed Explanation
Different organizations, such as NGOs and government agencies, often have temporary missions to help with disaster recovery. Once their contracts end, they move on, leaving behind long-term challenges unaddressed. This creates a gap in sustained care and adaptation to new circumstances in affected communities.
Examples & Analogies
Imagine a team of doctors who come to a town after a natural disaster to help heal the injured. Once they've helped everyone, they leave, but if some injuries need ongoing care, those people are left without support, showing the importance of lasting assistance in recovery efforts.
