Chapter 53, Problem 16

Do you drink coffee? A lot of people do—coffee is a major tropical crop, valued at over $100 billion per year. The most popular species of coffee, Coffea arabica, originated in Africa and is now planted extensively in Central and South America. The pest called the coffee berry borer beetle (Hypothenemus hampeii) moved along with the coffee and is a major problem for coffee farmers, sometimes destroying half of the coffee crop in mature plantations. Evaluate this statement: Leaving some natural forest in and around coffee plantations is a 'win-win' situation—a win for ecosystems and a win for farmers.

Video transcript

Hello everyone here We have a question that says the strategy in which high value crops are cultivated under a forest canopy that is intentionally modified or maintained is called what? So we have a crop rotation. Crop rotation grows different types of crops in the same area across the sequence of growing seasons. So A. Is incorrect be hydroponics, hydroponics is the process of growing plants in sand, gravel or liquid with added nutrients, but no soil. So B. Is incorrect. See urban agriculture? Urban agriculture is farming within an urban environment, especially the cultivation of food crops for human consumption. So C. Is incorrect, deforest farming. Forest farming is the cultivation of high specialty crops under a forest canopy that is intentionally modified or maintained. This forest canopy provides shade levels and habitat that helps the crops and favors growth and enhances production level. So D. Is correct. So our answer here is deep forest farming. Thank you for watching. Bye.

Scientists around the world are collaborating to understand how deforestation, climate change, and natural processes will interact to affect one of the most productive and biodiverse ecosystems on Earth. Many studies have raised the concern that positive feedback loops among numerous variables in the Amazon will cause an ecosystem tipping point—a rapid and irreversible transition from forest to grassland. Use the model in Question 14 as a tool to summarize a possible sequence of effects that could cause a transition from forest to grassland.

Do you drink coffee? A lot of people do—coffee is a major tropical crop, valued at over $100 billion per year. The most popular species of coffee, Coffea arabica, originated in Africa and is now planted extensively in Central and South America. The pest called the coffee berry borer beetle (Hypothenemus hampeii) moved along with the coffee and is a major problem for coffee farmers, sometimes destroying half of the coffee crop in mature plantations. Draw a simple model to compare the relative species richness and species diversity of these two coffee plantations: one is clear-cut and planted with only coffee shrubs, the other retains some natural forest. For symbols, use a few letters to represent different species of plants and a few numbers to represent different species of animals in a square 1-ha plot.

Scientists around the world are collaborating to understand how deforestation, climate change, and natural processes will interact to affect one of the most productive and biodiverse ecosystems on Earth. Journalists must be concise when reporting science news. Why might journalists and the public struggle to understand and discuss ecosystems ecology and global warming?
