Section C: The challenge of resource management common mistakes

Common mistakes

• Misunderstanding Agricultural Development Examples

  Students often confuse the advantages and disadvantages of agricultural development examples, failing to clearly identify them.

  Fix itTo fix this, students should create a clear list of advantages and disadvantages for each example, ensuring they understand how each point relates to the specific agricultural development.

• Misunderstanding Sustainable Practices

  Students often confuse organic farming with permaculture, thinking they are the same.

  Fix itClarify that organic farming focuses on avoiding synthetic chemicals, while permaculture is a holistic design system for sustainable agriculture that integrates land, resources, and people.

• Confusing Local and Global Examples

  Students often confuse local LIC or NEE schemes with global examples when explaining sustainable food supplies.

  Fix itFocus on specific local examples and their unique strategies to increase sustainable food supplies, ensuring you highlight their local context.

• Confusing Water Surplus and Deficit

  Students often confuse the concepts of water surplus and water deficit, thinking they are the same.

  Fix itTo fix this, remember that water surplus refers to areas where water availability exceeds demand, while water deficit indicates areas where demand exceeds availability.

• Misunderstanding Water Consumption Drivers

  Students often confuse the reasons for increasing water consumption, thinking it is solely due to rising population without considering economic development.

  Fix itTo fix this, students should remember that both economic development and rising population contribute to increased water consumption, and they should provide examples of each.

• Confusing Over-Abstraction with Pollution

  Students often confuse over-abstraction of water resources with pollution, thinking both are the same issue affecting water availability.

  Fix itTo fix this, students should understand that over-abstraction refers to the excessive removal of water from sources, while pollution involves the contamination of water, both of which impact availability but in different ways.

• Misunderstanding Water Insecurity Impacts

  Students often confuse the impacts of water insecurity with general water issues, failing to specify how it leads to waterborne diseases or food production impacts.

  Fix itFocus on the specific consequences of water insecurity, such as how lack of access to clean water can lead to health issues like waterborne diseases and affect agricultural productivity.

• Misunderstanding Desalination

  Students often confuse desalination with water recycling, thinking both processes are the same.

  Fix itEmphasize that desalination involves removing salt from seawater to make it drinkable, while water recycling involves treating wastewater for reuse.

• Misunderstanding Water Transfer Schemes

  Students often confuse the advantages and disadvantages of large-scale water transfer schemes, failing to provide specific examples.

  Fix itTo fix this, students should study a specific large-scale water transfer scheme, such as the California State Water Project, and clearly outline both its benefits (like increased water supply) and drawbacks (such as environmental impact).

• Misunderstanding Grey Water

  Students often confuse grey water with black water, thinking both are the same type of wastewater.

  Fix itClarify that grey water is wastewater from sinks, showers, and washing machines, while black water comes from toilets and contains harmful pathogens.
