Slide 1 - Natural ResourceManagement
Slide 2 - What is a natural resource?
- A natural resource any natural material that is used by humans
- For example oil, forests, water, etc.
Slide 6 - Earth was once very rich in Natural Resources
- The Earth was once so rich with resources that it could meet the demands of its inhabitants for a long time.
Slide 7 - Why do natural resources need to be managed?
- Because of the misconception that renewable resources are inexhaustible, natural resources are over used leading to concerns that will put the future plant, animal, and human society in serious risk.
Slide 8 - Increased Human Population
- As the population of humans continues to increase, the result will be less water, food, and other essential resources.
Slide 10 - Problem #1: Soil Erosion
- Soil erosion is a natural process, but can be sped up by improper management
- Runoff increases the amount of soil erosion
- Every year 3.5 million hectares are displaced because of water erosion
- Soil formation is very slow
- With a loss of soil nutrients, crop yields lower
Slide 11 - Management of Soil Erosion
- Recycle crop residues
- Recycle green and animal manures
- Integrated nutrient management into the soil
Slide 12 - Water is one of the most important natural resources for survival and economic development
- Water pollution
- 53 million hectares are irrigated
- Problem #2: Water
Slide 14 - Management: Water
- Water conservation
- Schedule irrigation
- Promote irrigation management
- Collect and store rain water
Slide 15 - Problem #3: Vegetation Usage
- 253 million m3 of firewood that is cut annually, but 40 million m3 would be sustainable
- 90 million cattle graze land that is estimated to support only 31 million
Slide 17 - Management: Vegetation Usage
- Afforestation – creating a forest where one was not originally
- Reforestation – replanting an area that used to be a forest
- Agroforestry – trees are grown around crops of pastureland
- Vegetation is essential for providing oxygen and removing carbon dioxide
Slide 18 - Additional Areas of Management
Slide 19 - Earth Summit Agenda 21
- The United Nations created a voluntary, non-binding plan that focuses on:
- Social and Economic Dimensions
- Conservation and Management of Resources for Development
- Strengthening the Role of Major Groups
- Means of Implementation
