Questions and Answers

Which of the following is not a method to increase food production?

Crop rotation

Organic farming

Deforestation (correct)

Intensive irrigation

What is the primary purpose of using green manure in agriculture?

To prevent soil erosion

To control pests and diseases

To reduce the use of chemical fertilizers (correct)

To increase water availability for crops

Why is the practice of overgrazing harmful to food resources?

It leads to soil compaction and reduced water infiltration (correct)

It increases the biodiversity of the ecosystem

It promotes the growth of native grass species

It enhances the fertility of the soil

Explain the concept of sustainable agriculture and how it can contribute to the improvement in food resources.

Sustainable agriculture refers to the practice of farming in an ecologically and ethically responsible manner. It aims to provide food and fiber for the current population without compromising the ability of future generations to meet their own needs. Sustainable agriculture can contribute to the improvement in food resources by promoting soil health, conserving water, and minimizing the use of synthetic inputs. Signup and view all the answers

Discuss the role of biotechnology in enhancing food resources and the potential ethical considerations associated with its use.

Biotechnology plays a significant role in enhancing food resources by allowing for the development of genetically modified crops that are resistant to pests, diseases, and environmental stress. However, the use of biotechnology raises ethical considerations related to food safety, biodiversity, and the potential long-term impacts on ecosystems. Signup and view all the answers

Evaluate the impact of climate change on global food resources and propose potential adaptive strategies to mitigate its effects.

Climate change has significant implications for global food resources, leading to shifts in agricultural productivity, increased frequency of extreme weather events, and disruptions to food supply chains. Adaptive strategies to mitigate its effects may include promoting climate-resilient crop varieties, implementing sustainable water management practices, and enhancing the resilience of food systems to withstand climate-related shocks.

Study Notes

Increasing Food Production

Methods to increase food production include improved farming techniques, crop rotation, and genetic modification.
Examples of non-methods include deforestation and over-reliance on chemical fertilizers.

Green Manure in Agriculture

Primary purpose: enhance soil fertility by adding organic matter and nutrients.
Improves soil structure and promotes beneficial microbial activity.

Overgrazing and Food Resources

Overgrazing leads to soil degradation, reducing land's productivity.
Causes loss of native vegetation and increases erosion, impacting food supply.

Sustainable Agriculture

Concept focuses on farming practices that maintain ecological balance.
Enhances food resources by promoting biodiversity, conserving water, and reducing chemical inputs.

Biotechnology and Food Resources

Biotechnology enhances food production through genetic modifications for pest resistance and higher yields.
Ethical considerations include potential risks to health, biodiversity, and the environment, alongside issues of food equity.

Climate Change and Global Food Resources

Climate change impacts crop yields through extreme weather, altering growing seasons and increasing pests.
Adaptive strategies include developing climate-resilient crops, improved water management, and sustainable land-use practices.
