“His research is aimed at increasing yields by growing crops next together”

# data[].attributes.body
This comes from a scene in the documentary where they are discussing one of the researchers in the field who is trying to find a way to make growing crops more sustainable in arid environments. In an article I read online, it states that poverty will not be ended by sheer will power alone nor ethical commitment. However, it will be ended by bringing the best of our thinking and the best of our science, together with ethical commitment (Sachs, 2008). I think what this points out is that we have to bring together our two best abilities to solve this massive problem. As the researcher is doing in the doc where he’s trying to figure out if we can increase yield of certain crops by growing them closer together therefore using less land space and ultimately being able to plant more plants.

“Water conservation has to be the greatest need among arid farming areas”

# data[].attributes.body
In the documentary they discuss ways for arid land areas to revitalize the land. One of the main components is water conservation and ways that they can improve it. In an article I found online the highlight is that the future of our planet’s food security will depend on how water and soil resources are managed today and in the future. These challenges can be met by maximizing soil and water conservation to develop sustainable systems essential to mitigate climate change and adapt to it (Delgado, August 2011). So water conservation plays a major contributing role not only for countries today but for the future. We must find a way to sustainably conserve as much water and soil as possible.

Additionally, it has been reported that climate change can increase potential erosion rates, which can lower agricultural productivity by 10% to 20% (or more in extreme cases). Climate change could contribute to higher temperatures and evapotranspiration and lower precipitation across some regions.

I think this quote applies to my theme because it talks about how much effort the research students at the University of Arizona have put into airid land research. Especially with crops like Maze soybeans and oil crops, all main crops grown in Sub-Saharan Africa and require less maintenance, especially useful for biofuels. An article I found online discusses how this type of research could provide a possible solution to the twin challenges of energy security and climate change. But the concern is that crop-based biofuels will increase net greenhouse gas emissions of feedstocks are produced by expanding agricultural lands (Gibbs, 2008). So they’re kind of stuck in the middle where they can solve one problem but it makes the other problem worse

This quote comes from the scene when they are in Cape Verde talking to one of the residents. To me it shows that we have made some progress in recent history to try to maintain the land by coming up with more reliable cultivation and farming methods. In the documentary they talk about how the students are Arizona do as much work as two people trying to figure out ways to combat desertification and make lands more arable. One article I found talks about how there are varying endowments of land, labor and climate. These differences lead to a wide spectrum of farming systems. Agricultural technologies that are cost-effective in some farming systems, are not in others (Binswanger, Pingali, 1988). So while irrigation may be effective in Cape Verde, it may be ineffective in other parts of sub-Saharan Africa. Highlighting one of the biggest challenges of slowing down desertification.

I chose this quote because it’s a little more eye opening and puts things more into perspective. Without proper education or resources the people can’t take care of the land leading to it becoming desert. The statistics really pop out to me and show that this is something that has been happening over time and now just recently.   One article in particular that I found, discusses how the narrative of desertification has been invoked for decades to facilitate and justify policy and legal changes that have systematically disadvantaged pastoralists and damaged the environment (Davis, 2005). So basically that people are using this data to push political agendas no matter the damage done to the enviornment or the people effected by it.
