25
Why is it hard to grow plants in the rainforest
The canopy blocks the sunlight and it’s too moist
26
What can shifting cultivation lead to
Unfertile soils and soil erosion
27
What is shifting cultivation
A method usually used by tribes where an area of trees are burnt and the ashes are mixed with the soil to grow crops and then after the soil becomes unfertile but eventually regenerates And is less damaging to the environment
28
Name 7 reasons why people destruct the rainforest
``` Trees for wood- furniture making etc. Clearing for farmers from cities Grazing land for cattle Using trees for fuel like charcoal Flooding valleys for hep schemes More roads and railways Clearing for mining for minerals like iron ore or gold ```
29
Why is grazing land for cattle bad
Soil becomes unfertile quickly so new areas are instantly being cleared
30
What are HEP schemes
Schemes that use water to generate electricity without needing water storage
31
How does deforestation effect the climate
Co2 increases as fewer trees to take in gas (less oxygen) | Greenhouse effect-co2 traps heat from earth and becomes warmer
32
How does deforestation effect wildlife
Plants for valuable medicines die out Homes of thousands of species disappear Species can become extinct as animal either moves away or dies
33
How does deforestation effect local people
People make living from rainforest-hunting, cooking and building Lose whole way of life Native Indians moved into reservations against their wishes Outsiders give disease to Indians who aren’t immune
34
How does deforestation effect soil
With no leaves or roots the soil become very poor With no tree roots, the top soil is washed away by heavy rain Soil too thin and poor for crops to grow well
35
How does the rainforest help Brazil
Increase jobs, money, buildings, facilities
36
Name 5 ways to sustain the rainforest with
``` Protected areas Sustainable logging Harvesting forest products Argo-forestry Eco-tourism ```
37
What is protected areas
44 percent of amazon is protected with nature reserves, national parks etc.
38
What is sustainable logging
Trees that are only cut when mature so younger trees can survive and trees are flown down river instead of making roads
39
What products do we harvest from the rainforest
Brazil nuts, rubber, vanilla pods, spices, plants with medicinal value
40
What is Argo-forestry
Growing trees in combination with crops, the trees shelter the crops and provide nutrients from decomposing plant matter
41
What is eco-tourism
Tourism that conserves the environment and improves the well-being of the local people
42
What is a favela
A small cramped town made of shacks on the outskirts of a Brazilian city
43
Name 6 problems with Favelas in Brazil
``` Overcrowding Employment Housing Crime Sanitation and health Steep hillsides ```
44
Why is employment a problem in favelas
Most people work in informal sector e.g. drivers, maids. poorly paid, irregular work with no benefits
45
What is a problem with housing in favelas
Built with basic materials, 12 percent have no running water, 30 percent have no sewage connection and 30 percent no electricity. Some people try and make illegal connection to pylons which can start fires
46
Why are steep hillsides a problem with favelas
Difficult for building roads and houses, everything like rubbish has to be carried in and out, landslides can occur after heavy rainfall wiping out houses
47
Why is sanitation and health a problem in favelas
Lack of running water and proper sanitation results in contaminated water giving off diseases like cholera
48
Why is Crime a problem with favelas
Many are controlled by criminal gangs involved with drugs and gun crime, police are reluctant to enter
49
Why is overcrowding a problem in favelas
20 of rios population live in favelas, 150000 people in one of the main favelas Rocinha, city authorities cannot keep pace with the supplying of homes, jobs and services such as hospitals and schools
50
What are 4 ways that people have solved some of the problems in favelas
Removal Site and services schemes Self-help schemes Mortar Carioca (Rio living )
51
What is Morar Carioca
a programme where Rio are trying to urbanise all favela communities. This involves pacifying police units and improving housing and infrastructure
52
What are two things they do for the morar carioca programme
Pacifying police units | Improving housing and infrastructure
53
What is pacifying police units
Permanent community police within favelas making it safer for residents and businesses
54
What did they do to improve housing and infrastructure
Got 40 local architects to redesign housing areas and new amenities provided
55
What is a problem with the Morar Carioca programme
People think it’s just a makeover for the Olympics, some residents forcibly evicted and housing is improved but job creation is more difficult
56
What are self help schemes
Favelas Improved by the residents and the authorities provide the materials.
57
What was a problem with self help schemes
Improvements were restricted by steep hillside and high density of housing
58
What is removal
During 1950s/60s favelas in central Rio we’re cleared and residents were forced to new housing on the outskirts
59
What happened with the removal development
Unsuccessful, residents moved back
60
What is the site and services scheme
Where authorities took control of building, in 1990s a project set aside 200 million pounds to improve 60 favelas. New brick homes with amenities and local services were built.
61
What was the problem with site and services schemes
