GIEL Cluster 1: Thinking Geographically Flashcards
1.1: Relationships between people and nature in their neighbourhood
Local communities and nearby nature areas:
-?
-?
-Are dependent on each other
-Mutually affect each other
1.1: Relationships between people and nature in their neighbourhood
Why are people dependent on nature?
-?
-?
-?
Example:
-Nature provides essentials like air and water for human survival
-Organisms like bees help pollinate crops for continuous supply of food
-Nature provides spaces for recreation and leisure activities, allowing people to bond with their family and friends, helping maintain humans’ physical and mental well-being
Example: NParks’ Therapeutic Gardens help connect people with nature and reduce stress which improves their physical, psychological and social well-being
1.1: Relationships between people and nature in their neighbourhood
Why are some nature areas also dependent on local communities to thrive?
-?
-?
Example:
-People in neighbourhoods may tend to the health of nearby nature areas, ensuring the plants and animals living there thrive.
-Individuals in local communities can encourage one another to enjoy nearby nature areas in a sustainable manner without causing irreversible damage.
Example: NParks organises various activities for schools during the week of international day for biodiversity in May. One example is the Green Wave campaign that aims to educate youths on the importance of protecting our natural environment.
1.1: Relationships between people and nature in their neighbourhood
Local communities and nearby nature areas mutually affect each others, bringing both benefits and harms to each other.
How do nature areas benefit people?
-?
-?
-?
-?
-The presence of green spaces and urban wildlife in neighbourhoods can enhance the mental health and well-being of local communities, also giving them enjoyment
-lowering temperatures
-removing pollutants
-providing space for recreation
1.1: Relationships between people and nature in their neighbourhood
Local communities and nearby nature areas mutually affect each others, bringing both benefits and harms to each other.
How do people bring benefits to nature?
-?
Example:
-?
-?
Example:
- Local communities can collectively raise awareness about the value of nature areas by encouraging positive behaviour that does not damage nature.
Example: The NParks Citizen Science initiative, Dragonfly, trains participants to identify different dragonfly species at their assigned sites, resulting in greater protection of the species by raising awareness of their importance in the environment. - Local communities can also organise/participate in conservation efforts
-Clean-up programmes to remove pollutants help restore natural habitats and provide a healthy environment for species to thrive
Example: The waterways clean-up programme organised by the Waterways Watch Society creates opportunities for schools to pick up trash from the Marina Reservoir
1.1: Relationships between people and nature in their neighbourhood
How does the presence of vegetation help lower temperatures?
-?
-?
-Provides shade and reduces the amount of direct sunlight reaching the surface
-Cools the surrounding air through evapotranspiration as the water that plants absorb through their roots is released into the air as water vapour. The process uses heat from the surroundings, thus cooling it.
1.1: Relationships between people and nature in their neighbourhood
How do nature areas remove pollutants?
-?
-?
-?
-During photosynthesis, vegetation absorbs carbon dioxide and other air pollutants while releasing oxygen.
-Leaves intercept small particles, which are washed to the ground when it rains.
-Wetland plants can trap suspended materials and absorb excess nutrients in the water, improving water quality.
1.1: Relationships between people and nature in their neighbourhood
How do nature areas provide recreational spaces?
-?
-?
-They offer numerous opportunities for outdoor activities
-Direct and frequent interactions with nature can benefit the health and well-being of people, reducing severity and occurrences of health conditions.
1.1: Relationships between people and nature in their neighbourhood
How do people bring disadvantages to nature?
-?
-?
-?
-?
-Causing soil erosion
-Damaging vegetation
-Worsening pollution
-Disturbing wildlife
1.1: Relationships between people and nature in their neighbourhood
How does nature bring disadvantages to people?
-?
-?
-Wildlife from nearby nature areas may harm people
-environmental protection may hinder development
1.1: Relationships between people and nature in their neighbourhood
How do people cause soil erosion and damage vegetation?
-?
-?
-?
Example:
-When people hike along non-designated trials in nature areas:
-They may cause soil compaction, preventing rainwater from infiltrating the surface, leading to higher surface flows and soil erosion as the flowing water washes away the soil particles.
-They may trample on vegetation, damaging plants and affecting their growth.
Example: In 2014, human activities led to severe soil erosion and habitat degradation in Bukit Timah Nature Reserve, resulting in the limiting of public access to the nature reserve for 2 years.
1.1: Relationships between people and nature in their neighbourhood
How do people worsen pollution and disturb wildlife?
-?
-?
-?
-?
Example:
-Littering can worsen pollution in natural areas
-Animals can get cut by metal cans/become entangled with plastic containers and bags
-Some animals may also mistake litter for food and consume them, which may cause the animals to get hurt and suffer, possibly leading to their death.
-Feeding wild animals may also lead to changes in the habits and behaviours of wildlife and human-wildlife can increase when animals associate food with people.
Example: Some people think they are helping wild animals by feeding them, but it actually does more harm than good. The Singapore law prohibits the feeding of any wild animals, with a fine of $5000 for the first offence
1.1: Relationships between people and nature in their neighbourhood
Human-wildlife conflicts may increase due to an increase in human-wildlife encounters. What are some reasons for increasing human-wildlife encounters in Singapore and why?
-?
-?
-?
-?
-?
-?
-[Urban expansion]
-Singapore continues to urbanise and develop, leading to natural habitats shrinking. Wildlife may venture out of nature areas searching for food/shelter, potentially increasing the frequency of human-wildlife encounters.
-[People’s growing interest in outdoor recreation]
-With growing interest, people are now spending more time in nature areas, increasing the frequency of human-wildlife encounters.
-[Greening efforts by the state]
-Singapore aims to bring nature back into the city to promote human-wildlife encounters.
1.1: Relationships between people and nature in their neighbourhood
Why may wildlife from nearby nature areas harm people?
-?
-?
-With the increase of wildlife population in the city, people who may not know how to deal with them may unintentionally provoke them, leading to attacks
-Some animals may be confused and fearful when they venture into unfamiliar urban spaces, increasing their likelihood to attack when fearful/triggered
1.1: Relationships between people and nature in their neighbourhood
Why may environmental protection be perceived to be limiting development?
-?
Example:
-Some people in local communities may feel that the protection of nature is done at the expense of their needs
Example: The Cross Island MRT Line was proposed to be built around, instead of under, the Central Catchment Nature Reserve to protect our largest primary rainforest.
Residents were afraid that this would:
1. Bring them inconvenience
2. Damage their property
3. Result in their homes being acquired to make way for the construction
However, the reserve is home to many critically endangered species. Construction of the MRT line may damage their habitat, affecting their survival.
