resource management Flashcards
why is food resource significant, and what are some inequalities
good diets lead to productivity and boosted economy, malnutrition leads to poor health and unproductivity
2 billion have poorly balanced diets lacking minerals and vitamins
US has most food production and most obesity, and still has hunger
why is water resource significant, and what are some inequalities
water is essential for crops and drinking
climate change causes supply imbalance
by 2025, 50 countries will be facing scarcity
why is energy resource significant, and what are some inequalities
needed for homes (light, heat, power), and for economic growth (power factories)
unbalanced between hics and lics
nees demand more as they become industrialised, trading pattern changes
physical water scarcity vs economic water scarcity
physical - not enough to meet everyones needs
economic - area cannot afford infrastructure to supply to people
what is the inequality in demanding high value food from lics
farmers in lics get paid little for food with high prices in the uk, supermarket and transport take most of money
what food demands are being made
exotic foods, out of season food, organic food, foreign food
why is food demand expanding
foreign travel and diverse population have changed eating habits
how can we reduce food miles and carbon footprint
agribusiness (large commercial farms with modern technology)
local sourcing - farmers markets reduce food miles, processing and packaging, and waste (imperfect food is sold)
example of food miles
lamb travels 18 800 km from new zealand
why do we need food from other countries e.g tomato
carbon footprint would be more in uk as the uk needs heated greenhouses
why is local sourcing good for food resource
food miles and carbon footprint reduced
less processing and packaging
less waste - shops dont sell “imperfect” food
describe the relationship between water supply and water demand
north and west have water surplus - higher rainfall and lower population
south and east have water deficit - lower rainfall and higher population
why is water hard to transfer
high cost
potential damage of ecosystems
greenhouse emissions from electricity needed for pump
what are the main causes of water pollution
agriculture - chemicals
urban - detergents, minute plastic (runoff)
industrial - mine water, oil spill
between 1990 and 2020, energy mix….
almost 75% fossil fuels to over 45% renewable sources
