ECOSYSTEM CONSERVATION | ENVIRONMENTAL GEOGRAPHY Optional for UPSC

Introduction

• Conservation is aimed at proper use, preservation and management of natural resources in such a way that they are always available in desired quantity and quality for judicious use by humans.
• R. Beazley (1967) defines conservation as the process of establishing and adhering to socially, economically, and politically acceptable norms, standards, patterns, or models of behavior when utilizing natural resources within a society.
• E.P. Odum (1971) outlines two primary objectives of a conservationist:
  
  • Ensuring the preservation of a high-quality environment that possesses aesthetic, recreational, and economic value.
  • Ensuring a sustainable supply of beneficial plants, animals, and materials by establishing a balanced cycle of resource harvesting and renewal.

Thinkers' Views on Ecosystem Conservation

1. Deep Ecology Perspective:

• Recognizes the intrinsic value of all species and ecosystems.
• Emphasizes the interconnectedness and interdependence of all living beings.
• Advocates for a shift in human attitudes and values towards nature.
• Arne Naess developed the concept of deep ecology and promoted the idea of humans as equal members of the Earth community.

2. Ecocentric Perspective:

• Places equal value on all components of the ecosystem.
• Rejects human-centered approaches and anthropocentrism.
• Stresses the need for ecological integrity and the preservation of natural processes.
• Aldo Leopold emphasized the importance of conserving the integrity, stability, and beauty of the biotic community in his influential book, "A Sand County Almanac."

3. Utilitarian Perspective:

• Focuses on the practical benefits humans derive from ecosystems.
• Supports conservation efforts based on economic or ecological benefits.
• Advocates for sustainable resource management and ecosystem services.
• Garrett Hardin proposed the concept of "tragedy of the commons," highlighting the need for regulations to prevent overuse and depletion of shared resources.

4. Anthropocentric Perspective:

• Emphasizes the value of ecosystems for human well-being and survival.
• Supports conservation efforts primarily for human-centric reasons.
• Promotes the idea of sustainable development and balancing human needs with ecological protection.
• Brundtland Commission views sustainable development as meeting the needs of the present without compromising the ability of future generations to meet their own needs.

5. Biocentric Perspective:

• Recognizes the inherent value of individual living organisms.
• Emphasizes the protection of biodiversity and the rights of non-human species.
• Advocates for conservation efforts that prioritize species preservation and habitat protection.
• Paul Taylor argued for the ethical consideration of individual living organisms and their right to exist in his book, "Respect for Nature."

Approaches to Ecosystem Conservation:

1. Protected Areas:

• Establish designated areas to restrict human activities and preserve natural habitats.
• Example: Serengeti National Park in Tanzania.

2. Sustainable Land and Resource Management:

• Adopt sustainable practices to minimize negative impacts on ecosystems.
• Example: Forest Stewardship Council (FSC) certification for responsible forest management.

3. Ecosystem Restoration:

• Restore degraded ecosystems to enhance their resilience.
• Example: Restoration of the Florida Everglades.

4. Biodiversity Conservation:

• Protect and promote biodiversity within ecosystems.
• Example: Conservation of biodiversity hotspots like the Western Ghats in India.

5. Community Engagement and Education:

• Involve local communities and provide education for better stewardship.
• Example: Indigenous community involvement in Amazon rainforest conservation.

6. Policy and Governance:

• Implement regulations and governance frameworks to enforce environmental standards.
• Example: Convention on Biological Diversity (CBD) for global biodiversity conservation goals.

7. Collaboration and Partnerships:

• Foster collaboration among stakeholders for coordinated efforts.
• Example: Great Barrier Reef Foundation for partnership-based conservation.

Challenges in Ecosystem Conservation

1. Habitat Loss and Fragmentation:

• Destruction of natural habitats and breaking ecosystems into smaller patches.
• Example: Deforestation in the Amazon rainforest.

2. Invasive Species:

• Introduction of non-native species that disrupt native ecosystems.
• Example: Brown tree snake in Guam.

3. Climate Change:

• Altered temperatures and precipitation patterns affecting ecosystems.
• Example: Coral bleaching due to rising ocean temperatures.

4. Pollution and Contamination:

• Pollution from various sources harming ecosystems and wildlife.
• Example: Chemical runoff in rivers causing fish kills.

5. Overexploitation of Resources:

• Unsustainable harvesting of natural resources leading to species depletion.
• Example: Overfishing of cod in the North Atlantic.

6. Lack of Awareness and Political Will:

• Insufficient understanding and support for conservation efforts.
• Example: Weak enforcement of environmental laws.

7. Socioeconomic Factors:

• Economic pressures and poverty driving unsustainable land use.
• Example: Dependence on forests for livelihoods in developing countries.

Case Studies of Ecosystem Conservation in India:

1. Western Ghats Conservation Network:

• It was established to protect and conserve the unique ecosystems found in the region.
• Agasthyamala Biosphere Reserve in Kerala and Tamil Nadu is a part of the Western Ghats Conservation Network. It is home to several endangered species and plays a crucial role in conserving the rich biodiversity of the region.

2. Sundarbans Mangrove Conservation:

• Efforts have been made to conserve and protect the Sundarbans mangroves, which serve as a crucial habitat for numerous species and provide important ecosystem services.
• Sundarbans Biosphere Reserve has been established to protect the mangrove ecosystem. It is home to the Royal Bengal Tiger and numerous species of birds, reptiles, and aquatic animals.

3. Kaziranga National Park, Assam:

• Conservation efforts in Kaziranga focus on protecting the rhinoceros population and the unique grassland and wetland ecosystems.
• The park has implemented strict anti-poaching measures, including the use of drones and armed guards, to combat poaching activities. These efforts have resulted in a steady increase in the rhinoceros population.

4. Silent Valley National Park:

• Conservation efforts in Silent Valley aim to protect the pristine ecosystem and its endemic species.
• Save Silent Valley campaign led to the cancellation of a hydroelectric project that would have resulted in the destruction of large tracts of the park. The campaign highlighted the importance of conserving ecologically sensitive areas.

5. Corbett Tiger Reserve, Uttarakhand:

• The reserve focuses on the conservation of the tigers and its habitat, which includes diverse ecosystems ranging from dense forests to grasslands.
• The introduction of community-based conservation programs in the villages surrounding Corbett Tiger Reserve has helped reduce human-wildlife conflict and increase local support for tiger conservation.

Ecosystem Management vs Conservation

Conservation is the end result while management is the means. We can say, Ecosystem management and conservation means "Managing human activities to conserve the ecosystem and prevent the ecosystem from degradation".

The following are the way to manage the ecosystem:

• Conserve the habitat of living organisms through afforestation, reforestation, a biosphere reserve.
• Improve biodiversity.
• Switch to organic farming.
• Limit the human population 
• Encourage renewable sources of energy like Solar, hydel, wind, etc.
• Use of less polluting fuels such as CNG, Hydrogen fuel.
• Reduce, recycle, and reuse the waste
• Use the system approach to conserve the whole biosphere on a totality basis as each component of the environment is interconnected.
• Encourage research on the development of eco-friendly technologies and green chemicals.

There are two methods of conservation:

• In-situ conservation: Species are conserved in their original habitat where they belong. For example, Biosphere reserve, National Park, Wildlife sanctuary.
• Ex-Situ conservation: Ex-situ conservation means conserving the species outside of their original habitat. For example, Zoological park, Botanical garden etc.
