Culture & Environment: Anthropological Approaches to Environmental Issues ANT3CAE

MODULE 4.2: Case study: local communities and glacial retreat in Peruvian Andes

Case study: Glacier hazard zones Cordillera Blanca, Ancash region, Peru (Carey 2014)

Cordillera Blanca; Ancash region, Peru

Summary: Culture and climate change • Anthropologists have an important role to play in understanding and

highlighting the human dimensions of climate change; • Climate change mitigation and adaptation projects are unlikely to

succeed without close understanding of the societies in which they are to be implemented; • Resilience in communities is embedded in historical, social, and

cultural constructions that govern social interactions and the material development of communities. • Climate change practitioners can promote resilience to the physical

and material components of a socio-ecological system; • However the cultural side of resilience requires that livelihoods that

fulfil material, moral and spiritual needs in the context of major environmental or political change need be maintained to ensure sense of continuity of meaning and coherence.

The IPAT Model

December 28, 2023/in Uncategorized /by Daniel Jennings

he IPAT model is a formula used to calculate the environmental impact on the environment caused by humans. It is described as I = P x A x T. The environmental impact is represented by the (I) in the equation. There are three main factors that influence the impact, and those factors include the (PAT) portion of the equation, which stands for Population, Affluence, and Technology. For this assignment, you will research a country of interest and use the country’s data to make an argument for which would have the highest Environmental Impact or (I), as part of the IPAT model.

• Research a country of interest and make a claim for its potential environmental impact. Use multiple pieces of supporting evidence in your claim considering Population, Affluence, and Technology advancements. You do not need to use actual calculations but should consider the data for your chosen country. • Use the data found to discuss the three factors that affect the country’s Environmental Impact (I), which are: Population of a Country (P), Affluence (A), and Technology (T). Include at least two (2) facts/evidence for each. • Discuss Population in terms of size, Affluence in terms of wealth or economy, and Technology as the country’s phase pf development or use and production of modern technologies. • Make a concluding argument for which of the three factors would have the highest Environmental Impact (I), as part of the IPAT model. Provide at least two (2) facts/pieces of evidence in your argument. Requirements: • Provide multiple pieces of supporting evidence in your claims, using at least two (2) scholarly resources. • Include all references and citations formatted correctly in APA. • Paper should be one to three pages in length, with additional Title and Reference pages. • Use complete sentences and appropriate grammar and spelling.

Ques2on 1:

From a strictly sustainability point of view, explain succinctly the concept of “interdependence” among the environment, society, and economy. Use a real-world example to show these principles.

Ques2on 2:
What is the relationship between overfishing and the “Tragedy of the Commons”? Propose a solution for this dilemma.

Ques2on 3:
Explain in detail the concept of the “triple threat.”.

Ques2on 4:

A particular country A, in order to decrease its water insecurity level, decides to divert a significant part of the current of a river that crosses the territory of country B as well. Country B retaliates by increasing the rates of goods exported from country A. Provide an example of: 1) An economic conflict; 2) A social conflict arising from this diplomatic crisis. Do you consider that the shared building of water infrastructure (distribution and treatment) would be a good starting point for the talks between these two countries? Why? Justify your answer.
