Energy

Agriculture is a major

consumer of energy,

both directly (cultivation,

harvest, processing,

refrigeration, distribution)

ong>andong> indirectly (fertilizer,

pesticides, other inputs)

Water is a highly energy

intensive industry (energy

= 40% of cost of water in

developing countries)

Groundwater depletion

leads to higher energy use

for extracting / desalinizing

water

Climate change demong>andong>s

retreat from fossil fuels,

investment in new energy

systems

Extreme weather can

severely impact oil

production (e.g. hurricanes

in Gulf of Mexico)

20

Food / long>andong> use

Higher energy prices lead

to higher food prices as

input ong>andong> transport costs

increase

Biofuels create arbitrage

relationship between food

ong>andong> fuel, pulling food costs

upwards in line with energy

Biofuel cultivation leads

to increase in demong>andong> for

Deforestation for firewood

Lower water availability

has negative effect on crop

yields, can make some

crops unsuitable for areas

Changes in water

management (dams,

irrigation, etc.) can affect

viability ong>andong> productivity of

long>andong> downstream

Short term yield variance

due to rising temperatures

Reduced yields through

extreme weather events

Reduced yields through

changes in precipitation

ong>andong> water availability

Desertification, long>andong> ong>andong>

soil degradation will

increase with climate

change

Water

Higher energy costs lead

to higher water costs

because of energy used

in extracting / pumping /

processing it

Water essential for

hydroelectric power

generation (c. 16%

of global total power

generation)

Increased water use for

irrigation can affect water

resources (e.g. shrinking of

Aral Sea)

Long>andong> use change affects

water management (e.g.

wetlong>andong> drainage reduces

flood resilience)

Climate-driven changes

in precipitation; increased

droughts

Changes in water

availability e.g. through

glacial melting

Climate change

Emissions drive climate

change

Some air pollution

dampens climate change

by reducing radiative

forcing

Energy security concerns

may lead to more coal use

CO2 emissions from

agriculture energy use

(cultivation, processing,

refrigeration, distribution)

Methane emissions from

livestock, rice cultivation;

deforestation leads to

methane emissions as trees

decompose
