Q.1 Q.2 Q.3 Q.4 Q.5 Q.6 Q.7 Q.8 Q.9 Q.10

Q.1

Consider the case study given below and answer the following question:

Case Study: Protecting the Coral Reefs of Raja Ampat, Indonesia

Location: Raja Ampat, a stunning archipelago in Indonesia famed for its thriving coral reefs, biodiversity, and diving tourism.

Challenges:
-Overfishing: Unsustainable fishing practices, including blast fishing and cyanide fishing, have depleted fish stocks and damaged coral reefs.
-Pollution: Plastic pollution, agricultural runoff, and sedimentation from coastal development all threaten the delicate marine ecosystem.
-Climate Change: Rising ocean temperatures and acidification are bleaching and killing coral, the foundation of the reef ecosystem.

Initiatives:
-Marine Protected Areas (MPAs): Establishing and enforcing MPAs restricts harmful fishing practices and allows reefs to recover. Raja Ampat boasts one of the largest MPAs in Southeast Asia, covering over 1.5 million hectares.
-Community-Based Management: Local communities play a crucial role in protecting their reefs. The Coral Triangle Initiative focuses on empowering them through sustainable fishing practices and alternative livelihoods like ecotourism.
-Sustainable Aquaculture: Farming fish responsibly reduces pressure on wild stocks and provides alternative income for fishermen. Locally managed fish farms in Raja Ampat demonstrate successful alternatives to overfishing.
-Coral Restoration: Innovative techniques like coral nurseries and transplantation help regenerate damaged reefs and restore marine biodiversity.

Outcomes:
-Fish stocks are rebounding: The Raja Ampat MPA has shown a significant increase in fish biomass within its boundaries, demonstrating the effectiveness of protected areas.
-Improved water quality: Reduced pollution and sedimentation contribute to healthier corals and a more vibrant marine environment.
-Empowered communities: Local involvement in conservation fosters environmental stewardship and provides sustainable economic opportunities.

Raja Ampat serves as a beacon of hope in marine conservation, demonstrating the effectiveness of community-driven, multi-pronged approaches to protecting life below water. By tackling overfishing, pollution, and climate change, we can safeguard the future of these vital ecosystems and the communities that depend on them.

In the case study, it is mentioned that coral reefs confront challenges from pollution and climate change. How do these challenges interact to negatively affect Raja Ampat's coral reefs?

1. Pollution weakens coral reefs, making them more susceptible to bleaching and mortality as ocean temperatures rise.
2. Climate change alters ocean currents, causing an increased accumulation of pollutants near reefs, adding to their stress.
3. Pollution can harm reefs, but it doesn't significantly affect their vulnerability to climate change impacts.

Q.2

In a city prone to heatwaves, a group of students proposed a rooftop garden initiative to combat the urban heat island effect. How does the presence of rooftop gardens contribute to reducing the urban heat island effect?

Q.3

A city is expanding its wastewater treatment infrastructure to improve the quality of treated water released into the environment. As part of this development, engineers and environmental experts are reviewing the different stages of wastewater treatment to ensure the most effective processing of sewage.

In the wastewater treatment process, which stage involves the breakdown of organic matter by microorganisms in the absence of oxygen?

Q.4

Consider the following statements and choose the correct option:

1. Debris accumulation in oceans primarily consists of organic waste, which enhances marine biodiversity by providing habitats for various species.
2. Sustainable aquaculture involves utilising antibiotics to control diseases and enhance fish growth in farms.
3. Coastal development and shoreline alterations significantly impact marine habitats or disrupt the natural flow of sediments in coastal areas.
4. Overfishing contributes to the creation of dead zones due to the imbalance in marine ecosystems caused by the removal of certain fish species.

Q.5

The graph below demonstrates a 50% reduction in post-harvest food losses achieved by a cooperative of farmers through enhanced packaging and transportation practices. What specific strategies in packaging and transportation could account for this significant success?

Q.6

During a science fair, a student presented a project on the impact of wildfires on climate change. They highlighted that wildfires release vast amounts of carbon dioxide, methane and nitrous oxide into the atmosphere as shown in the table given below.

What inference can be made from this presentation?

1. Wildfires can act as a positive feedback loop, contributing to further warming and potentially more frequent fires.
2. Wildfires are primarily responsible for the rising levels of greenhouse gases in the atmosphere.
3. All wildfires should be suppressed to prevent any carbon dioxide, methane and nitrous oxide emissions.
4. The release of greenhouse gases from wildfires is balanced by the absorption of carbon dioxide by new plant growth.

Greenhouse Gas Amount Before Wildfire (tons) Amount Released by Wildfire (tons) Increase (%)
Carbon Dioxide
(CO2)		 30,00,000 10,00,000 33.33%
Methane (CH4) 1,00,000 50,000 50%
Nitrous Oxide
(N2O)		 10,000 5,000 50%

Q.7
