Study Notes
Wildlife Protection and Displacement
- Many species are listed in Schedule I & II of the Wildlife Protection Act, 1972, highlighting their endangered status.
- The Narmada valley project is anticipated to displace over one million people, marking one of the largest rehabilitation challenges acknowledged by the World Bank.
- Displacement of tribal communities leads to economic deprivation and a threat to their cultural heritage, including beliefs, rituals, and traditions closely linked to their environment.
- Tribals, predominantly from unprivileged scheduled castes and tribes, have lived in these areas for generations, creating complex socio-economic upheavals post-displacement.
Water Resources
- Water covers approximately 97% of the Earth's surface, with most organisms containing 60-65% water by composition.
- Unique properties of water: exists as a liquid from 0° to 100°C, has high specific heat, high latent heat of vaporization, and acts as an excellent nutrient solvent.
- Factors contributing to floods include deforestation, overgrazing, industrialization, and global warming, with devastating flood events recorded in India and Bangladesh (e.g., floods in 1970, 1988, and 1991).
- Bangladesh utilizes moderate flooding for agriculture, but severe floods lead to catastrophic losses, including one million deaths in 1970 and 140,000 in 1991.
- Proposals for national-level river networking aim to mitigate flooding issues.
Drought Management
- Approximately 80 countries experience frequent droughts, often exacerbated by high population growth and poor land practices.
- Anthropogenic activities like overgrazing and deforestation contribute to desertification, worsening drought conditions.
- India has faced increasing desertification, notably in Maharashtra, due to high water demand crops like sugarcane.
- Strategies to combat drought include mixed cropping to optimize production and social forestry initiatives, although improper implementation can lead to adverse effects.
Water Conflicts
- Water scarcity due to uneven distribution often results in conflicts at both national and international levels.
- Middle East conflict arises over shared water resources (Jordan, Tigris-Euphrates, and Nile), with countries vying for control affecting agriculture and population sustainability.
- Notable tension exists over the Nile, where Ethiopia’s planned upstream projects threaten Egypt's water supply, crucial to its arid landscape.
- The Indus Water Treaty (1960) allocates river rights between India and Pakistan, yet ongoing damming poses risks to the Indus delta's health.
Major Metal Reserves and Applications
- Aluminium: Reserves in Australia and Guinea; used in packaging, transportation, and electronics.
- Copper: Held primarily by Chile, USA, and Canada; crucial for electrical and construction uses.
- Iron: Vast reserves in the CIS and South America; essential for heavy machinery and steel production.
- Platinum and Gold: Significant reserves in South Africa; used in electronics, automotive, and medical applications.
Soil and Water Management Issues
- Waterlogging from excessive irrigation leads to soil saturation, depriving roots of air and reducing crop yields, prevalent in Punjab and Haryana.
- Salinity affects one-third of the world's cultivable land, with significant areas in India suffering from salt accumulation due to poor irrigation practices.
- Saline and sodic soils pose long-term agricultural challenges, necessitating careful water management strategies to ensure sustainable crop production.
