About how much of the global land use is for high-quality"cropland"? Where are these croplands usually found and how is this threatened by urban growth. In Canada, 7% of the best ag land was lost to new urban growth. Is this 7% of the total land area, or 7% of what proportion of the area? Why does this make a difference. For comparison, where are the highest quality agricultural lands in Oregon and are these lands threatened?

Although many of us might not like super-sized cities, what are some of the environmental and ecological benefits from having people live more in cities? Explain for example, less sprawl, recycling, emissions control, and other environmental impacts. Megacities and urban areas are growing around the world. What proportion of the world's population live in cities. What are the five largest cities in the world. What are the five largest cities in the "West"?

Define "sprawl" What are the 6 interacting factors that promoted sprawl? In your own words, describe the difference between having interacting factors and a set of individual causes. Explain how these factors work together. What does this complexity mean for reversing sprawl? (this is a key question -- don't ignore.)

List several extractive and non-extractive uses of forests. How does using extractive of non-extractive approaches to forests relate to the other services forests provide (such as clean, year-round water)?

Analysis and Synthesis questions: This is a 3 point question on the quiz, so it's worth thinking about. |
|
Urban growth. It's not just the population of the city but the footprint. Translate that point into our I = PAT framework. What are technologies that could human impact more per person in an urban area than in a rural area? Use this framework to compare a big rich city (economically stable) to a city with slums. What are potential negative impacts of a large poor population that could be mitigated with technology?

Land use changes in the Amazon have lead to big impacts on the environment and ecology. What do you think (from the on-line reading) were underlying global driving factors and what were the more localized, proximal causes? What strategies do you think you need to address these causes at different scales?

Sprawl is the result of interacting factors. Describe how individual policies or conditions, that are not necessarily damaging on their own and were put in place by well meaning governments, can interact in a way to lead to poor land use, i.e. sprawl. Can you think of a metaphor from medicine or business that could be used to explain this? Can you think of a way to reverse sprawl that doesn't require some uber-governmental agency imposing another pattern of development (think of how "smart growth" addresses the problem by explicating values and goals)? |
