What does the zoning plan of the Central Amazon Conservation Complex include?
AMAZON CASE STUDY.

Primitive zone - land of great natural value where there has been minimum human activity. Greatest level of protection.

Intensive zone - environment has already been significantly altered by human activity. Still protected, but some economic activity is allowed.
Special use zone - land on which the core services required to monitor and protect the natural rainforest are located.

What was Tanzania like in the early 20th century?SAVANNA GRASSLAND CASE STUDY.

Study These Flashcards

Under British rule.
Wild game was hunted for fur and ivory.
Serengeti plains weren’t settle on extensively by Europeans - the tsetse fly and a low seasonal rainfall deterred commercial cattle ranching and crop plotting.

Study These Flashcards

1921.
To protect lions - viewed by Europeans as vermin.
The Serengeti Park was created 30 years later.

SAVANNA GRASSLAND CASE STUDY.

Study These Flashcards

Independently managed by the Tanzanian government.Economic recession meant there was a lack of finance for conservation projects.

Important revenue source. 9,000 visitors per year. Despite sustainable management, approx. 200,000 animals are illegally killed by poachers every year. Declining number of warthogs, giraffes, buffalos ect.

What has recently happened regarding management for the Serengeti National Park and Ngorongoro Conservation Area, Tanzania? SAVANNA GRASSLAND CASE STUDY.

Buffer zones - Community Wildlife Management Areas. Local people are encouraged/have legal rights, to make decisions regarding the management of wildlife. Hoped to help curb poaching.

Traditional way of life is being threatened. Scarce grazing land. Pop. pressure - 2% annual growth. BR - 36 per 1,000 women per year. 36% live below the poverty line - increased pressure on resources

How has agriculture changed regarding the Serengeti National Park and Ngorongoro Conservation Area, Tanzania? SAVANNA GRASSLAND CASE STUDY.

Development of irrigation systems - enabled commercial agriculture. TNCs have offered incentives to village communities to grow biofuels.

42,000km-2 land. 1/3 of its territory. UK - only 1/10 is protected. The main aim is to preserve the country's natural rich heritage and to provide secure breeding grounds for its flora and fauna, safe from the conflicting interests of a growing human population.

Where is the Sundarbans Reserved Forest, Bangladesh, located? How big and why? TROPICAL MONSOON FOREST CASE STUDY.

Delta of the Ganges, Brahmaputra and Meghna rivers of the Bay of Bengal. 21st century - 10,000km-2. Roughly half the size it was 200 years ago. Intense population pressure in Bangladesh. 1,000 people per square km, compared to 200 in 1901. Large areas have been cleared.

What threats are faced in the Sundarbans Reserved Forest, Bangladesh? 1/3. 3. TROPICAL MONSOON FOREST CASE STUDY.

1. Climate change - sea levels are rising 3mm year-1. Will cause flooding of low-lying delta land, retreating shorelines, soil salinisation and water table changes. 2. Water abstraction - from upstream rivers for irrigation when dry. E.g. The Farraka Barrage 1974, Ganges River. Resulted in 40% reduction in flow when dry. Increased salinity of the land/water. 3. Deforestation - Himalayas. Greater silt volumes - deposited by the delta. Alters ecosystem balance.

What threats are faced in the Sundarbans Reserved Forest, Bangladesh? 2/3. 2. TROPICAL MONSOON FOREST CASE STUDY.

1. Population - 3 million live in small villages around the Sundarbans. The area provides livelihoods for 500,000 fishermen, woodcutters and grass/honey gatherers. 2. Fishing camps - major disturbance. Illegal hunting/trapping e.g. turtles. Nutrient-rich waters - rich harvest of shellfish e.g. shrimp and prawn. Crustaceans form the largest biomas proportion.

What threats are faced in the Sundarbans Reserved Forest, Bangladesh? 3/3. 2. TROPICAL MONSOON FOREST CASE STUDY.

1. Water pollution - industries around the ports of Khulna and Mongla have particularly affected aquatic wildlife. 2. Natural disasters - November 2007 cyclone killed 3,000. Cyclone Sidr caused damage to 40% forest. Foliage stripped from branches, larger trees uprooted. The Forest Department's entire operational capacity was lost when all equipment was destroyed. Without outside help - may take 15 years for parts to recover.

What is the vegetation of the Sundarbans Reserved Forest, Bangladesh, like? TROPICAL MONSOON FOREST CASE STUDY.

Vast netowrk of rivers, mudflats and islands - chars. Vegetated by mangroves - salt-tolerant trees. Are restricted to the intertidal zone along the coast. Act as natural buffers against storm surges. Protects land from tropical cyclones.

What are the animals of the Sundarbans Reserved Forest, Bangladesh, like? TROPICAL MONSOON FOREST CASE STUDY.

Royal Bengal tiger - 350. Estuarine crocodile. Indian python. Spotted deer/wild boar - tiger prey - 'man-eater' reputation. 9 species of kingfisher, eagles, herons, storks.

How is the Sundarbans Reserved Forest, Bangladesh, managed? | TROPICAL MONSOON FOREST CASE STUDY.

UNESCO World Heritage site in 1997. Biosphere Reserve in 2001. Its protection is considered to be of international importance. 7 conservation areas, including 3 wildlife sanctuaries. Managed by the Forest Department. Make up 15% of the eco-region. Wildlife 1974 act - illegal to cultivate land within the conservation areas, or to introduce domestic animals, hunt, damage or set fire to the vegetation.

What are the management struggles regarding the Sundarbans Reserved Forest, Bangladesh? TROPICAL MONSOON FOREST CASE STUDY.

Not enough staff/structures in place to enforce the law. Require more cross-boarder cooperation with India. More financial support from official aid sources and NGOs. Plans need to include a high degree of local community involvement to allow sustainable use of the forest. Schemes to generate income e.g. aquaculture, the development of alternative energy sources, local crafts and animal husbandry are required.
