Year 12 Climate change and agriculture: Flipped learning summary by Lisa Steciuk https://padlet.com/list4/10a96blw4gjqinss What is soil degradation? How is climate change impacting soil quality? What are the likely negative impacts of climate change on agriculture in general? en-us 2020-06-12 06:12:14 UTC 2020-06-15 01:23:49 UTC hello@padlet.com aly https://padlet.com/list4/10a96blw4gjqinss/wish/626524805 Soil degradation: The decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes.
impact of climate change on soil quality:
due to extensive agriculture, soil quality has decreased and when soil is damaged, it releases carbon dioxide into the atmosphere, which increases climate change, causing the Earth to overheat.
change will most likely be negative, floods and droughts for example will lead to lower crop yield and increased pressure from weeds.

- more intense droughts and floods in agricultural regions, will damage/kill crops]]> 2020-06-15 01:17:51 UTC https://padlet.com/list4/10a96blw4gjqinss/wish/626524816 sam w https://padlet.com/list4/10a96blw4gjqinss/wish/626524861
Soil degradation: The decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes. 

Impacts of soil erosion:
One handful of soil has more organisms that there are on earth 
  • When soil is damaged it releases CO2 into the atmosphere - it results in global warming 
  • Acidifies  our oceans - less carbon sink 
Overall impacts: 
  • More frequence and intense droughts and floods in many regions 
  • Loss of land through sea-level rise and associates salination 
  • Reduction in water available for irrigation 
  • The prices will rise for most important agricultural crops such as rice, wheat, maize and soybeans 
  • Higher feed and meat prices
  • Reduce growth in meat consumption and cause a falling cereal consumption -> food insecurity 
  • CO2 helps plants grow but it also helps weeds and invasive species grow more 
  • Could make our food less nutritious 
  • Over the next 30-50 years, CO2  concentrations will increase to about 450 parts per million by volume 
  • Most impact on C3 species such as wheat, rice and soybeans 
  • Sugar cane and rice straw slash and burn practices

1) As populations grow, so does the demand for food production and so there is an increase in agricultural activity and soil degradation as a result
2) When soil is damaged it releases CO2 into the atmosphere which contributes to the enhanced greenhouse effect 
3) Carbon can be transferred back into the soil (flux) by promoting afforestation as plants pump carbon back into the soil
4) The "4 per 1000" initiative was started by the French in 2015 with the goal of demonstrating that agriculture, particularly agricultural soils, play a crucial role where food security and climate change are concerned ]]> 2020-06-15 01:18:09 UTC https://padlet.com/list4/10a96blw4gjqinss/wish/626525031 Chris chch21 https://padlet.com/list4/10a96blw4gjqinss/wish/626525054 Soil Degradation - Decline in soil condition  caused by improper use of poor management, usually for agricultural, industrial or urban purposes
Soil Erosion - Removal and transfer of soil particles from one place to another, usually be wind or running water.
-Average temp will increase by 1 degree in the next 30-50 years
-Distribution of wild crop realties, an increasingly important genetic resource for the breeding of crop, will be severely affected
-More frequent and intense draught
-co2 concentration will increase to about 450 parts per million by volume

climate change is impacting soil quality by the increase in CO2 in the atmosphere. This leads to less carbon for the soil which is vital to stimulate growth of plants

Many of the world’s cultivated soils have lost 50% of its carbon stocks.
impacts
In the next 30-50 years CO2 concentrations will increase by450 part per million by volume. C3 species expected to be higher (wheat, rice, soybeans)
Heat: In the next 30-50 years temp Is likely to rise by at least 10C. Increased number of heat waves + warm nights. Fewer frost days + longer growing seasons in temperate zones
Hydrological cycle: more frequent and intense droughts and floods in agricultural regions. Can damages and destroy crops

How is climate change impacting soil quality - more frequent and increase in intense drought and flood. This destroys agricultural region as soil erosion and degradation occurs.

Soil erosion: The removal and transfer of soil particles from one place to another, usually by wind or running water.  It occurs in varying degrees in all soils and while it may be a natural process, it is often aggravated by the actions of people or sudden increases in rainfall.

Economic consequence: Prices for the most important agricultural crops will rise (rice, wheat, maize and soybeans). Leading to higher rates of food insecurity globally.

afforestation, plants take in atmospheric carbon during photosynthesis, pumping the carbon down into the roots to feed microorganism in the soil. Solutions can be keeping soils covered with plants, increasing crop diversity, composting, carefully plan to graze. Carbon-rich soils are extremely beneficial absorbing substantial amounts of water during floods and then providing it to plants in times of drought - carbon sequestration. Carbon-rich soils also make the land much more productive. Healthy soils are a huge sink for carbon.

1.  as population grows, the demand for agricultural products increases resulting in the need to clear more land and thus causing an increase in deforestation. it also causes overgrazing and use of chemicals such as fertilisers.
