Subsistence: crops produced feeds farmer and their family

Commercial: crops produced for sale ( cash crops )

 •Usually refers to large-scale farming and business activities such as commercial farming, processing, packaging, distributing & retailing 

•Places importance on scientific and business principles in farming, such as by investing in the research & development of food crops.

•Larger companies-> able to withstand the impact of changes in environment(eg. damage to crops caused by pests or flooding)

•Larger Companies-> greater financial capacity to absorb losses, and can invest on food production(including research into producing crops with greater crop yield)

2)-A third of global food production will be at risk
-4m sq km more of desert
-Increase in water scarcity

3)-Limiting temperature rises by meeting the goals of the paris agreement.

-Empower people in the danger zones to reduce the impact and increase their resilience and adaptive capacity.

-More usage of technology such as greenhouses to facilitate a more optimum temperature ?

A increase in greenhouse gas emissions leads to a rise in temperatures and rainfall patterns altering. This can cause an increase in food production in Nordic regions, while food production has also slowed down due to more area being converted into deserts, shrinking the amount of space for crop production.

(b)

Water scarcity increases in certain areas, lack of food causes an increase in prices for food. But also food production can increase in areas where it is currently slow like the Nordic regions

(c)

Decreasing the amount of emissions to prevent more greenhouse gases from being emitted and empower people and societies in danger zones to increase their resilience and adaptive capacity.

Generally i would also suggest DCs to participate in vertical farming so they’re less reliant on LDCs for food production especially in times where food production is slowing down. 

Implementing laws, fines or increasing the carbon tax for countries, also more investment into green technology

2.)-rising temperatures could increase food production in some areas that are currently less productive,such as the Nordic region

-many areas were likely to suffer large increases in water scarcity ,

-safe area would shrink drastically, mostly affecting south and south-eastern Asia and Africa’s Sudano-Sahelian zone

3.) supply water to areas that are suffering from water scarcity, use technology to create spaces that are able to increase food production? impose laws to control the greenhouse gas levels 

2. Impacts: about 95% of current crop production takes place in areas they define as “safe climatic space”, or conditions where temperature, rainfall and aridity fall within certain bounds. Under 1.5C to 2C of warming, the boreal forests of northern America, Russia and Europe would shrink from their current 7m sq miles to about 6m sq miles by 2100. In a high emissions scenario, only 3m sq miles would remain, the researchers forecast.

3. - government can provide more water when there is a drought. 
- Greenhouses can be built

b) If temperatures continue to increase, up to 1/3 of world crop production will be at risk, particularly affecting areas with warmer climates such as southeast asia and regions in africa. 

c) Educating the public on reducing food and water waste, as well as how to lead lifestyles that have a lower carbon footprint such as by using less energy.
