Environmental Ecology, Biodiversity and Climate Change
What the official syllabus says
UPPCS Preliminary Examination, Paper I: General Studies-I:
General Issues on Environmental ecology, Bio-diversity and Climate Change - that do not require subject specialization.
General Issues on Environmental ecology, Bio-diversity and Climate Change - that do not require subject specialization, General awareness of the subject is expected from candidates.
Note: Candidates are expected to have general awareness about the above subjects with special reference to Uttar Pradesh.
Topics in detail
General awareness, not specialisation, is expected: the concepts below, the main laws and agreements, and protected areas and species in the news.
Ecology
- Ecosystem: structure (biotic and abiotic) and function; food chains and food webs; trophic levels; ecological pyramids; energy flow
- Biogeochemical cycles: carbon, nitrogen, water, phosphorus
- Ecological succession; population and community ecology (niche, keystone species, symbiosis)
- Types of ecosystems: forest, grassland, desert, freshwater, wetland, mangrove, coral reef, marine
Biodiversity
- Genetic, species and ecosystem diversity; endemism
- Biodiversity hotspots, India's four (Himalaya, Indo-Burma, Western Ghats and Sri Lanka, Sundaland); megadiverse countries
- Threats to biodiversity: habitat loss, invasive species, poaching, pollution
- IUCN Red List categories; species in India of special concern (for example the tiger, Gangetic dolphin, gharial, great Indian bustard, swamp deer)
- In-situ conservation: national parks, wildlife sanctuaries, conservation and community reserves, biosphere reserves, tiger and elephant reserves
- Ex-situ conservation: zoos, gene banks, seed banks, botanical gardens
- Project Tiger (1973), Project Elephant (1992), Namami Gange and dolphin conservation
Environmental laws and bodies
- Wildlife (Protection) Act 1972; Water Act 1974; Air Act 1981; Forest (Conservation) Act 1980; Environment (Protection) Act 1986; Biological Diversity Act 2002; Forest Rights Act 2006
- National Green Tribunal (2010); Central and State Pollution Control Boards; environmental impact assessment
Pollution
- Air pollution: pollutants, Air Quality Index, stubble burning, vehicular emissions
- Water, soil, noise, plastic, e-waste and biomedical waste; solid waste management rules
- Ganga pollution and its control
Climate change
- Greenhouse effect and greenhouse gases; global warming and its effects (sea level, glaciers, extreme weather, agriculture)
- Ozone depletion; the Vienna Convention and Montreal Protocol
- UNFCCC (1992), Kyoto Protocol (1997), Paris Agreement (2015); IPCC reports in outline
- India's National Action Plan on Climate Change (2008) and its missions; India's net-zero target (2070) and commitments
- Carbon credits, carbon sinks, mitigation and adaptation
International conventions
- Ramsar Convention on wetlands (1971), CITES, Convention on Migratory Species, Convention on Biological Diversity and its Protocols (Cartagena, Nagoya), UNCCD
- UN Environment Programme; Global Environment Facility
Overlaps
Protected areas, wetlands and pollution in the state are on Uttar Pradesh: Geography and Environment. Environment and biodiversity are written topics of Mains General Studies III, and the environment of Uttar Pradesh of General Studies VI.
