Increasing food output by Mind Map: Increasing food output

1. Composting

1.1. Composting is the natural process of decomposition and recycling of organic material into a humus rich soil amendment known as compost.

1.2. Benefits

1.2.1. food waste can be used Reduces solid waste disposal fees

1.2.2. reduces use of artificial fertilizers - more environment friendly

2. Foreign Investments

2.1. More Money = More Invest = Possibly more output

2.1.1. Agricultural work can be replaced by machinery and some people may lose jobs No jobs = no money, no money = no food Provide an opportunity for people to shift from primary to other industrial sectors

2.2. Increased output will be shipped to foreign countries to satisfy their needs, not benefiting domestic country

3. Farming Techniques

3.1. Crop rotation

3.1.1. Practice of growing different types of crops in the same area according to season Slow down and prevent soil degradation It lessens need for chemical as Planting different crops breaks weeds and pests life cycle and prevents them from multiplying Reduces the spread of soil-borne diseases Reduces rain drop impact , surface runoff and

3.1.2. Benefits Maintain soil fertility Reduces soil erosion Reduces reliance on chemicals

3.2. Terracing

3.2.1. Practice of growing crops in pieces of sloped plains that have been into receding flat surfaces or platforms that look like steps. It conserves the soil as it slows rapid surface runoff which would erode the soil as it wipes of the top layer depositing it further down the hill

3.3. Pesticides

3.3.1. Use of Pesticides to protect crops from pests or diseases so as to prevent any crop losses

3.4. Fertilizers

3.4.1. To enrich the soil so that the crops get enough nutrients to grow.

3.4.2. However, if not done well, could lead to eutrophication & other environmental impacts

4. Green Revolution

4.1. Combination/application of science and technology to increase food productivity

4.1.1. High yielding varieties of crops India 1967 case study

4.1.2. Genetic engineering Food Technology

4.1.3. Mechanization

4.1.4. Chemical fertilizers

4.1.5. Irrigation

4.2. Benefits

4.2.1. food production can meet increasing demand in developing nations

4.2.2. reduce balance of payments deficit due to reduction in imports

4.3. Problems

4.3.1. affects natural food web

4.3.2. genetically engineering food may alter genes unpredictably

5. Controlling water supply

5.1. Investing in the building of dams (for example) to control the supply of water so food can still be produce in the event of a drought

5.2. To prevent over water of the crops. Which can lead to soil erosion and death of the crops.
