food waste in the world
roughly 1/3 of the world’s food is never eaten
in low income areas, how does waste come about
generally unintentional and occurs on farms or during storage or distributionh
how can we combat food waste in low income areas
improve infrastructure for storage, processinf, and transportation
in high income areas how does food waste come about
over serving
food thrown away due to quality standards
how do we prevent food waste in high income areas
major interventions required at the retail and consumer level
food we waste is responsible for what percent of global emissions
8%
how would plant rich diets reduce emissions
reduces demand on animal agriculture, reduces land clearing, fertilizer use, and ghg from these activtiies
how do refrigerants affect the atmosphere
fluorinated gasses are used as refrigerants and they have a potent ghg effect
managing leaks and disposal of these chemicals can avoid emissions in buildings and landfills
what are pros of using wind turbines
is competitive with or less expensive than coal-generated electricity
have small footprints (no more than 1%)
takes one year or less to build a wind farm
how can we reduce emissions from refrigerants
- lower demand for applicanes
2.replace refrigerants with substaanecs with lower global warming impacts - increase refrigeration efficiency of appliances to control leakage
- recover, reclaim, recycle, and destroy refrigereants
how can solar photovoltaics help to reduce emissions
they can be used at utility scale with hundreds or thousands of solar panels to replace the fossil fuel electricity generation
how much of global electricity generation is estimated to be from utility scale solar photovoltaics
just over 3%
how can clean cooking reduce emissions
can reduce pollution from burning wood or coal in traditional stoves and protect human health
An estimated ___ of families in low-and middle income countries were mainly using cookstoves fueled by traditional woord or coal stoves for cooking
43%
Improvement in air quality due to removal of solid fuel cookstoves could avoid _____premature deaths globally between 2000 and 2050
10.5 million
recent scenarios have predicted that almost ____ of global electricity could come from solar PV by 2050.
60 percent
silvopasture
Integrates trees, pasture, and forage into a single system
why is silvopasture helpful for the environment
Incorporating trees into agriculture improves land health and increases carbon sequestration
Pastures with trees sequester five to 10 times as much carbon as those of the same size that are treeless while maintaining or increasing productivity and providing a suite of additional benefits.
perennial staple crops
Provide important foods, such as bananas, avocados, and breadfruit
Production of trees and other perennial crops for staple protein, fats, and starch
These perennial staple crops yield as well or better than their annual staple crop competitors
They also sequester impressive carbon in soils and above-ground biomass
Thrive under many different conditions that annual crops can’t
multistrata agroforestry
Mimic the structure of natural forests
Layered trees and crops achieve high rates of both carbon sequestration and food production
One or more layers of crops grow in the shade of taller trees
