Water Efficiency, 4. Improved Farm Practices, 5. Nutrient Management, 6. Agricultural Insurance, 7. Credit Support, 8. Markets, 9. Livelihood Diversification and 10. Access to Information

Notes:
Wildlife corridor or Green corridor is an area of habitat which connects wildlife populations separated by human activities. Wildlife corridors may be both natural or created. These corridors help animals that move between isolated patches on a daily basis and also those that migrate between habitats seasonally.

Notes:
The Umbrella Group is a loose coalition of non-European Union developed countries. It was formed after the adoption of the Kyoto Protocol. The umbrella group consists of 12 countries although there is no formal membership.

Notes:
Phenotype refers to a set of observable characteristics of an individual or group resulting from the interaction of its genotype with its environment. Gene pool refers to the stock of different genes in an interbreeding population.

Notes:
Blue Revolution means the adoption of a package programme to increase the production of fish and marine products. The Blue Revolution in India was started in 1970 during the Fifth Five-Year Plan when the Central Government sponsored the Fish Farmers Development Agency.

Notes:
Biotic components are the living things that shape an ecosystem. Examples of biotic components include animals, plants, fungi, and bacteria. Abiotic components are non-living components that influence an ecosystem. Examples of abiotic factors are temperature, air currents, and minerals.

Notes:
The Vikramashila Gangetic Dolphin Sanctuary (VGDS) resides in Bhagalpur district, Bihar, covering about 50 km along the Ganges. It holds the distinction of being India’s only sanctuary for its national aquatic animal, the Gangetic dolphin. The Ministry of Environment, Forest, and Climate Control (MoEFCC) declared the Gangetic dolphin as the National Aquatic Animal of India and launched the Ganges River Dolphin Conservation Programme in 1997 – a testament to its dedication to preserving this unique species.

Notes:
Blowing or moving air is called wind. The speed of wind may vary from 5-10 km/h (gentle breeze) to 700-800 km/h (tornado). The speed and direction of wind is affected by the following factors :

• Location on the earth
• Rotation of the earth
• Local conditions
• Height from the ground

Notes:
The Iguaçu National Park is a World Heritage Site straddling the borders of Brazil and Argentina. This locale is famous for the panoramic Iguaçu Falls, consisting of about 275 individual falls, spanning 2,700 meters. Most importantly, the park serves as a sanctuary for numerous rare animals like jaguars, ocelots, and jaguarundis. The phenomenal waterfall isn’t only a top tourist attraction but also an important habitat for species like the great dusky swifts. Proclaimed a World Heritage Site by UNESCO in 1984, the park exemplifies global importance in wildlife conservation.

Notes:
The Pantanal Conservation Area, recognized as a UNESCO World Heritage Site, accounts for 1.3% of the vast Pantanal wetland in Brazil and spans across 187,818 hectares. It provides shelter for more than 650 bird species, 325 fish species, and 80 mammal species, including giant armadillo and jaguar. The area’s unique ecosystem extends from floodplains to the Amolar Mountains, supporting diverse habitats and maintaining regional fish stocks. Moreover, it is an all-important breeding ground for wetland birds and refuge for globally threatened species like the hyacinth macaw. Additionally, it is a Ramsar Wetland and a UNESCO Man & Biosphere Reserve.
