Land Change

It is crucial to study the global impact of land change because over the last recent decades, humans have been responsible for changing the global environment. This continues to be more of a concern as the population on Earth increases more and more. So it is necessary to understand how land change affects the environment, what socio-economic causes affect it as well as how it affects processes that affect global change. With agriculture and forestry, humans have been a significant reason that many landscapes have been completely modified and have impacted other creatures or plants that depend on these landscapes. The demand for these resources also grows because of the growing human population. Some social systems have attempted and been successful when dealing with land change and climate changes. People in wealthier countries are “buffered” from the impacts of climate change more so than people in third world countries. Many natural inputs like water or energy, have been modified by climate change and will continue to as rainfall and temperature patterns fluctuate in the coming years. These land changes could increase the exotic creature population by affecting the natural habitat of a certain landscape. Irrigated and non-irrigated cropland would be an example of how landscape changes due to land use practices. In the coming years, people will be more challenged to meet their needs for their resources while being as sustainable as possible and responding to these global environment changes effectively.

  1. You state that some wealthier populations are more buffered from the impacts of climate change more so than people in third world countries. This seems like somewhat of a general statement. Even people in wealthier countries feel the impacts of hotter summers, or decreased rainfall, or the rising oceans. I feel like more information should be provided for a reader to understand that claim made. I feel like maybe it would be good to say that they don't feel the impacts "as much" because of increased access to water resources or alternate resources (like if the forests were failing, timber could be found elsewhere and imported, etc.), whereas poorer countries cannot just import everything they need.
    Otherwise very interesting piece!

  3. How can GIS be used to show the effects of land change? Also could it be useful in showing the difference between how countries experience climate change and how they contribute to it? To support the claim that Rachel is talking about above.

  4. As people are challenged by the impacts of their land use, how will they be sustainable and respond to the environmental changes? As both challenges they are partially human caused.
