The Precision Agriculture Revolution

The Precision Agriculture Revolution | STEM Connections | Scoop.it

"Thousands of years ago, agriculture began as a highly site-specific activity. The first farmers were gardeners who nurtured individual plants, and they sought out the microclimates and patches of soil that favored those plants. But as farmers acquired scientific knowledge and mechanical expertise, they enlarged their plots, using standardized approaches—plowing the soil, spreading animal manure as fertilizer, rotating the crops from year to year—to boost crop yields. Over the years, they developed better methods of preparing the soil and protecting plants from insects and, eventually, machines to reduce the labor required. Starting in the nineteenth century, scientists invented chemical pesticides and used newly discovered genetic principles to select for more productive plants. Even though these methods maximized overall productivity, they led some areas within fields to underperform. Nonetheless, yields rose to once-unimaginable levels: for some crops, they increased tenfold from the nineteenth century to the present.  

Today, however, the trend toward ever more uniform practices is starting to reverse, thanks to what is known as 'precision agriculture.' Taking advantage of information technology, farmers can now collect precise data about their fields and use that knowledge to customize how they cultivate each square foot."

Development and diffusion of agriculture-

This article explains how agriculture has developed and grown for thousands of years, and today with our technology, we can do what seemed impossible to the past peoples.

This article represents Development and Diffusion of Agriculture by showing how in our past years, we could mostly only do substinence agriculture, but today with technology, we can do so much more, with so much less people.

Land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts-

This article explains how today we have the best technology we have ever created agriculture-wise, but with this, more land has been used. But thanks to precision agriculture, we can use data to determine where we can use the least amount of raw materials needed, thus helping protect more land than before.

 This article demonstrates land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts by showing how with the technology today and precision farming, we can use less raw materials than ever before, thus helping lessen global impact.

Speaking the “Language” of Spatial Analysis via Story Maps

Speaking the “Language” of Spatial Analysis via Story Maps | STEM Connections | Scoop.it

"Spatial analysis has always been a hallmark of GIS, the 'numerical recipes' which set GIS apart from other forms of computerized visualization and information management. With GIS we pose questions and derive results using a wide array of analytical tools to help us understand and compare places, determine how places are related, find the best locations and paths, detect and quantify patterns, and even to make spatial predictions."

GIS is a key tool in spatial analysis, but it can also be a driving force in using math, science, technology and (yes) geography as interdisciplinary ways of teaching the curriculum.  StoryMaps can be rich with images and videos, but also filled with data at a variety of scales.  What stories can you tell in this rich, visual format?  What visual template shown might lend itself best for that sort of project?

Integrating Geography and History

"This 18-stanza poem by Kit Salter, beautifully captures the importance of geographic thinking in any history/social studies curriculum.  This was shared by Dr. Vernon Domingo and the slides of his keynote address titled, Integrating Geography and History are available here."

It was my privilege to hear my good friend and fellow geo-evangelist, Dr. Vernon Domingo recently as he shared ideas on the importance of integrating geographic analysis in historical inquiry.  He shared a fabulous poem by Kit Salter, one of the pioneers in the Network of Geographic Alliances.  I'll only share the first stanza here:


    How can there be a separate scene,
    For history without place
    How can there be events in time,
    For which there is no space?

This is a resource i feel would be relevant to those students who struggle to be egaged in their reading

This can be used on readers on many different level

the reading maps foccus on language arts, Its description is communicated through charts, graphs, and maps intead of normal paragraphs and text

Shelby Porter's comment, September 30, 2013 11:19 AM
I feel the skill of reading a map is very important, but it becoming less prevalent in classrooms. Teachers may find it more difficult to teach and therefore are not going in depth with it. I remember as a child in grade school we would color maps or have to find where the states are. We never were taught how to fully understand the uses of a map and all the different ways they are used and how to read them. It is becoming a lost skill in a world that needs to be more appreciative of geography.

Learn What Spatial Analysis Can Do for You

Learn What Spatial Analysis Can Do for You | STEM Connections | Scoop.it

"This Massive Open Online Course (MOOC) is for people who know something about data analysis and want to learn about the special capabilities of spatial data analysis. Spatial analysis focuses on location to gain a deeper understanding of data. Spatial analysis skills are in high demand by organizations around the world. You'll get free access to the full analytical capabilities of ArcGIS Online, Esri's cloud-based GIS platform. Previous experience with GIS software is helpful, but not necessary for tech-savvy problem solvers. Could you and your career go places with spatial analysis?"

This course starts tomorrow...if you've wanted to learn about GIS with a no-risk on-ramp, this looks to be a safe bet from the worldwide leader in geospatial software.  While a grad student at Penn State, I was a TA for a course designed by David DiBiase (the instructor of the MOOC), and I still refer back to that class as one of the best courses to teach geographic skills for the non-geography major.

It is interesting to find out that in this specific article there is controversy over the looting of tombs over 5,000 years ago as soon as the deceased were buried there were many more looting acts taken place. The Arab spring is an important landmark to think of when relating this to the reading.

Lauren Sellers's curator insight, May 20, 2014 11:51 AM

This describes human characteristics that defined this region because it shows how ancient artifacts are being unearthed through new-age technology.

Felix Ramos Jr.'s curator insight, March 19, 10:49 AM

Space archaeology only makes sense.  If we have the capability for satellites to take pictures of earth from above why shouldn't it be used for archaeological analysis?  I am sure that this is only the tip of the iceberg as far as what we will see in the future from this specific field. This article/video just lends more credibility to the fact that Archaeology should function as an interdisciplinary field.

Seth Dixon's curator insight, June 29, 2013 11:20 AM

While many in the geography education business bemoan student's lack of global awareness as a rationale for geography education, this is the key angle that I feel we should be pushing: the workforce.  We currently are not producing enough students with geospatial skills in the United States to fill the jobs (one of the problems with geography being classified as a social science).  Now that is a practical reason to support geography that non-geographers can understand.
