lets families take from cereal bank during the lean season & pay back when they’re making a profit seasonally
prevents starvation & malnutrition (1.9 million malnourished children in 2023)
prevents travel by long distances for food
Positive outcomes for the food bank
Reduces malnutrition and starvation for the whole community
protects vulnerable children, large young dependency ratio
412,000 children with severe acute malnutrition
What’s a challenge for the local food bank

Local response to deforestation (ICF)
ICF (International Conservation Fund)
Founded in 2019, located South-East Amazonia, Brazil
protect land with:
guard posts that discourages potential invaders
create sustainable incomes with Brazil nut harvesting
annual income for kayapo communities
aim: To ensure Kayapo culture, economic, political and territorial autonomy.
outcome: kayapo have successfully defended their land, satellite images reveal no deforestation.
negatives
Potential conflicts with external interests
limited funding for long-term projects
reliance on consistent local governance
National response to deforestation (The forest code)
Forest code (national)
Introduced 1985
Updated from 1965-2023
Legally covers rivers, forests, soils
Enforced with inspections, sanctions (administrative and criminal)
aim: balancing agricultural land use as well as restoration of degraded areas
to conserve biodiversity
outcome: critics argue that the revised Forest Code has led to a decline in environmental protections and increased deforestation.
positives
claim to be “ensuring environmental protection”
Actively monitoring deforestation through rural environmental registry (CAR)
negatives
reduced required forest cover on private land from 80% to 50%
code has been difficult to enforce
increased deforestation, loss of up to 190 million acres of forest
unclear regulations and inadequate support for sustainable practices
conflicts with local communities
Global response to deforestation (REDD+)
Redd+
Introduced in cop19
Purpose: incentivizing developing countries to reduce greenhouse gas emissions by preserving their forests
Stands for reducing emissions from deforestation and forest degradation
Aims:
reduces emissions from conservation of forest-carbon stocks
sustainable management of forests, enhancement of forest carbon stocks
Outcomes:
projects have led to significant carbon storage and improved livelihoods, others have yielded mixed results
failure to create a large-scale funding mechanism
not successful, why
Impacts on wellbeing in local communities have been mixed
Deforestation is still a significant issue
backlash from political groups in favor of weaker environmental policies
lack of transparency
difficult to assess overall effectiveness

habitat loss
increased soil erosion
climate change exacerbation and biodiversity decline, often driven by agriculture
urbanization
mining
Human and natural causes for deforestation
human
Agricultural expansion
Projects to improve infrastructure
Poor forest management
Wars and civil distribution
Pursuit of economic development
natural
Insects, pests, diseases
Wildfires
Short term: Storms, drought, landslides, volcanos
Long Term: Climate change
Interconnection between human and natural causes
Overall, human activity is the driver of deforestation
Human activities are speeding up natural climate change
Human disturbances like selective logging and land clearing, forest edges become more prone to natural disturbances
Clearance areas for agriculture and cattle ranching are more susceptible to fires
Causes for deforestation (agricultural expansion)
responsible for 73% of global deforestation
supported by government subsidies to promote food security
cattle ranching accounts for 80% of forest clearing in the Brazilian rainforest
Causes for deforestation (poor forest management)
lack of workforce capacity to enforce laws
international criminal police organisation (INTERPOL) estimates forestry crimes total 51 billion USD - $152 billion USD per year (3/4 of this comes from Indonesia and Brazil)
high corruption because forest products provide high financial rewards
logging licenses often encourage rapid wasteful exploitation for short term financial gain
Causes for deforestation (wildfires)
affects about 3% of global forest area each year
primarily in dry temperate & tropical regions
e.g australia, canada, chile, greece
some forests naturally regenerate after a fire, or even depend on fires to regenerate
Causes for deforestation (pursuit of economic development)
underlying driver for deforestation
as countries develop economically, deforestation occurs rapidly
event in warmer climate
forest dieback has been documented n every vegetated content over the past three decades
impacts of deforestation on the economy
Brazil could face losses of $317 Billion per year if amazon deforestation continues - short term gain for individuals
non-timber forest products need forest ro survive (rubber, Brazil nut and açai) - contributes income to 6 million households in Brazil
forest sector makes up 1.2% of brazils GDP - most of deforestation that happens is illegal
impacts of deforestation on society
social
indigenous communities - 422 indigenous reserves, 700,000 indigenous people live in reserves
deforestation on indigenous lands has increased by 129% between 2013 and 2021
health - air pollution = respiratory issues
vulnerable groups will me harmed more, long term effects from toxic pollutants can cause cardiovascular diseases and premature death
impacts of deforestation on the environment
environment
biodiversity - 3 million species live in the amazon rainforest
estimated 137 plant, animal, insect species lost in amazon east year
waters absorbanccy is reduced, as well as quality and increased erosion
adding to climate change - reducing carbon sink, less trees to take in more carbon

About the smaller workforce in Japan
Workforce has been declining since 1995
because of aging population
less people contributing to the economy
Social drivers for a smaller workforce
Social/cultural drivers
low birth rate - 6
high life expectancy - 84
work habits - 11% of employees work >60 hours per week (8 hours each day w/ no weekends)
family-based support for the elderly means less time at work, making money and contributing to the economy
Traditional gender roles - women leave the workforce once they get married and have children
What is the population trend in japan
Aging and shrinking population
One issue the population faces becuse of shrinking & aging population
smaller work force, smaller domestic market, less women having children
Context for smaller work force
Employment-to-population ratio is 60.2% in 2024
minimum mandatory retirement age is 60
uneven old age dependency ratio
working-age population fell 13% (from 87.3 million in 1995 to 73.7 million in 2024)
low immigration - represent only about 2% of Japan's population (approximately 2.93 million people in 2020)
Only about 11% of Japan's land is arable
Context for smaller domestic market
smaller population directly results in a smaller domestic market and less demand for goods and services, negatively impacting the country's Gross Domestic Product (GDP)
Context for women having less children
Childbearing in Japan is strongly linked to marriage, but marriage rates are falling
average age of marriage for Japanese women has increased to 29.9 years. This results in fewer reproductive years to have children
Long working hours - averaging up to 60 hours per week for employees
11% working > 60 hours
More than 50% of women stop working after the birth of their first child
husbands contribution to household tasks never exceed 5.3 hours per week on average
husbands have estimated 1 hour of childcare contribution compared to 3 in the USA and Germany
what are the challenges faced because of the smaller work force, smaller domestic market, less women having children
WF -Increased Elderly Dependency Ratio - elderly dependency ratio increased rapidly
7 economically active individuals supporting each person over 65 in 1985
2.8 in 2010
projected to fall to 1.7 by 2035
less government revenue from taxation
Benefits for the aged account for about 70% of Japan's total social security expenditure
exceeds ¥2,200 billion annually and is expected to grow
proportion of the 0 to 14 age group has significantly reduced, almost by one-third between 1950 and 2020, to 12%

HCO (Holocene climactic optimum)
warm period from 9,000-5,000 years ago, started 15,000 years ago after age age (glacial termination)
large ice sheets covering NA and Europe started melting
event consisted of 4oC increase near north pole
southern Europe experienced cooling
avg temp change declines rapidly due to latitude
why?
Milankovitch cycles - change in earths orbit = increased solar radiation in the horthern hemisphere
Greenhouse gas levels - co2 & methane concentration in the atmosphere began to rise due to human activities (deforestation & agriculture)
compared to today
temps warmer than now
tropics and parts of southern hemisphere were cooler than average
LCM (Last Glacial Maximum)
18,000-20,000 years ago
last ‘ice age’ where land ice was dominant
8% (today is 3% )of world surface was covered by ice (including land & sea ice)
25% (today is 3%) of earths land surface was covered in ice
sea level was approximately 112-125cm lower than today
surface temp was 4-6oC colder than average median temp
Cooling was distributed unevenly
Antarctica stayed the same
North Pole changed - ice formed over land meaning it melted quicker
forest cover was less expensive, climate caused cooler and drier rainfall
grassland became more widespread
africa had grasslands in the south & deserts in the north (closer to equator)
aisa had a mix of tropical deserts in the west, alpine deserts in the north
grasslands in indian subcontinent

Horn
Arete
Terminal moraine

Cirque
Calving
General process for melting
accumulation
temps are cold
snow collects, adds to mass
starts with first autumn snow
older snow compacts
ablation
mass starts to reduce (melting, calving or sublimation/evaporation)
starts late spring
warm air & sun melts snow and ice into water
calving happens, otherwise slow shrinkage
all new snow disappears from lower reaches of glacier
remaining snow form hard layer of firm
new equilibrium line is made
Human and natural causes for melting
natural
variation in solar energy
not consistent
milankovitch cycle correspond with periods of glaciation
volcanic activity
significant amounts of dust and gas ejected into the air = both warming and cooling
deep water currents
aka thermohaline circulation
driven by differences in water density due to temp and salinity
human
localized addition of heat
activities of everyday living into the atmosphere (industrial processes - heating, cooling, transport)
alteration of landscapes
changed in albedo (light refraction)
clearance of forests
urbanization
changed in soil moisture
Interconnection between human and natural causes of melting ice in Greenland
amplification
humans accelerate naturally occurring processes
like fluctuations of cold and warm periods
rate of melting that is faster than what would occur through natural cycles alone
release of more greenhouse gasses (co2) from burning fossil fuels has strengthened the natural greenhouse effect
human-induced warming is laid on top of the natural cycles - increasing global average temp
positive feedback loop
Ice reflects most sunlight back into space, helps keep planet cool
Ice melts naturally after ice age - darker ground exposed = absorbs more sunlight as heat - more melt
Humans cause initial melt from activities - natural melt is accelerated more with more ground exposed
Causes for melting ice sheets (plate tectonics)
redistribution of land masses change climates as continents move into different latitudes
changes sunlight reflection and ocean heat balance
long term process
Causes for melting ice sheets (increase in global temperatures)
human and natural
global temps have increased by at least .94oC since 1880
estimated 40% of ice in the arctic melting is due to warming
more ablation over accumulation
could be from volcanic activity or output of greenhouse gasses
Causes for melting ice sheets (cryoconite)
airborne material from industry, desert dust and volcanic particulate
melting is increased because it settles on ice pats
reduces albedo (light refraction) and accelerates melting
Causes for melting ice sheets (population change)
60% of all emissions come from cities
emissions come from reduction of forest of forest cover and mangroves (carbon sinks)
methane from thawing permafrost enhances emissions
421 ppm of co2, pre industrial co2 was 250 ppm
impacts of melting ice on the economy
economy (fishing)
warmer water brings different fish species - shrimp, cod, salmon
increase in fishing industry
large companies adapt better than small independent companies - struggle to buy new equipment (e.g bigger boats, nets, processing machinery, crab pots & trawlers)
fishing export has grown from 138 million USD (1980) to 470 million USD (2014) - 34 years
impacts of melting ice on the society
society
changing diets - replacing traditional foods (seal & whale) to imported food
- native fish are leaving because of increase of freshwater from melting ice
people leaving/migration - women aged between 15-25 leaving for education or better job offers and resources and more housing accessibility
average of 2,544 people leaving every year (data from 2012-2022)
impacts of melting ice on environment
environment
water salinity changing because of glacial meltwater
more land for agriculture - land increased 30%, no. of farms decreased by 20% both in the last 20 years
lack of nutrients in soil after melting means bad soil quality
rate of melting increased - 5x greater in last 20 years than pre-industrial levels
land cover (purpose, define)
