Introduction
- Natural resources are essential components of the Earth's ecosystem, supporting life and development.
- The major types of natural resources include land, water, forests, and minerals.
- Proper management and conservation of these resources are critical for sustainable development.
Land Resources
- Land is a finite and critical resource used for agriculture, habitation, and infrastructure.
- Supports
Introduction
- Natural resources are materials and components provided by nature that are essential for human survival and development.
- They are categorized into renewable and non-renewable resources based on their availability and rate of replenishment.
- Understanding these resources is crucial for sustainable development and conservation.
Renewable Resources
- Renewable resources are naturally replenished on a regular basis.
- Examples include
Introduction
- Conservation initiatives are aimed at protecting endangered species and maintaining ecological balance.
- Project Tiger and Project Elephant are flagship programs initiated by the Indian government to conserve these iconic species.
- These projects involve habitat protection, reducing human-wildlife conflict, and promoting sustainable coexistence.
Project Tiger
- Launched in 1973 by the Government of India to protect the dwindling tiger population.
- Aims to
Introduction
- Ex-situ conservation refers to the conservation of species outside their natural habitats.
- It is a complementary approach to in-situ conservation, focusing on protecting endangered species in controlled environments.
- Key methods include zoos, seed banks, and botanical gardens.
Zoos
- Zoos serve as centers for the conservation and captive breeding of endangered species.
- They help protect species from threats like
Introduction
- In-situ conservation involves protecting species in their natural habitats to ensure their survival and reproduction.
- It aims to maintain the natural processes and interactions within ecosystems, preserving genetic diversity.
- Key methods of in-situ conservation include the establishment of national parks, wildlife sanctuaries, and biosphere reserves.
National Parks
- National parks are protected areas established to conserve w
Introduction
- Biodiversity is under constant threat from various human-induced activities and natural changes.
- Key threats include poaching, the spread of invasive species, and the impact of climate change.
- These threats disrupt ecosystems, reduce species diversity, and destabilize ecological balance.
Poaching
- Poaching refers to the illegal hunting, capturing, or killing of wildlife, often for commercial purposes.
- It targets species for their
Introduction to Habitat Loss and Fragmentation
- Habitat loss refers to the destruction or degradation of natural habitats, making them unsuitable for species survival.
- Habitat fragmentation is the division of large, continuous habitats into smaller, isolated patches, disrupting ecosystems.
- These are major drivers of biodiversity decline globally, affecting species survival and ecosystem functioning.
Causes of Habitat Loss
- Deforestation for agriculture, logging, and urban
Introduction to Biodiversity
- Biodiversity refers to the variety of life forms on Earth, encompassing all species, genetic variations, and ecosystems.
- It plays a crucial role in maintaining the ecological balance by supporting ecosystem stability and resilience.
- Biodiversity ensures the functioning and productivity of ecosystems.
Role of Biodiversity in Ecological Processes
- Primary producers, such as plants and algae, convert solar energy into food, formi
Introduction to Biodiversity Hotspots
- A biodiversity hotspot is a region with a high level of species richness and endemism that is under significant threat from human activities.
- The concept of biodiversity hotspots was introduced by Norman Myers in 1988.
- For a region to qualify as a biodiversity hotspot, it must have at least 1,500 species of vascular plants as endemics and must have lost at least 70% of its original habitat.
- Globally, there are 36 biodiversity hotspots
Introduction to Biodiversity
- Biodiversity refers to the variety of life forms on Earth, encompassing all living organisms and ecosystems.
- It is crucial for the functioning of ecosystems and the survival of life.
- The three main levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity.
Genetic Diversity
- Genetic diversity refers to the variation of genes within a species.
- It encompasses differences in DNA among indivi
