Under Prospecta Colombia 2012, an event organized by the Universidad Nacional Abierta y a Distancia, issues were raised and discussed related to the growth and development of cities. Nerdo Cavernas talks with the most prominent speakers present at this important event.

The rapid population growth in large urban centers of the world has made it necessary to look for alternatives to development in order to make cities suitable for living. PROSPECTA, an international event, aims to promote ideas of change by thinking about society's future, starting with proper planning and development.
University of Chicago scientists are collaborating with researchers at the Argonne National Laboratory to build a wide-ranging urban sensing project in Chicago known as the Array of Things (AoT). A network of 500 computer nodes gather data on various livability factors from all over Chicago. These factors include climate, weather, air quality, noise levels, and traffic. The data is gathered in real time and helps individuals understand the complexities of city dynamics. Part of the “Science Nation” series.
Our modern lifestyle has increased the amount of garbage we produce, and we are running out of space to store it. Fortunately much of the waste can be reused, and urban waste collectors hold a fundamental place in the recycling process.
A good story is not necessarily a true story. In this episode, host Joe Hanson takes a look at a few of the most famous incorrect factoids in science. He also gives some tips on how to not be fooled by scientific urban legends. Part of the "It's Okay to Be Smart" series.
Host Peter Tonge visits the Weston Maple Sugar Project in Weston, Massachusetts. Shows the process of making maple syrup from tapping a maple sugar tree to boiling sap in a sugar shack. The second part of the program focuses on the basics of planning a garden in late winter. Also explains how to mix and apply liquid fertilizers. Originally aired as an episode of "The Good Green Earth."
These city kids from Boston may not look like conventional farmers, but they’re spending part of their summer getting their hands dirty. They’re learning how to build solar-powered hydroponic systems that grow organic vegetables without soil. With support from the National Science Foundation, Boston College educator Mike Barnett and his team developed the Urban Hydrofarmers Project to engage students in math and science through hydroponic farming and green energy technology. And, because the teens sell what they grow at farmers’ markets, the students get to experience green entrepreneurship. Barnett and his team have also partnered with the STEM Garden Institute to bring hydroponic farming into classrooms throughout the U.S. Part of the National Science Foundation Series “Science Nation.”
In contrast to the peaceful wildlands featured in the prior segments, the urban campus of the University of California-San Diego (UCSD) seems like an unlikely place to find field biologists studying juncos. But in the early 1980s, some juncos decided to make this atypical urban and coastal habitat their year-round home. Since then, scientists have documented a remarkable array of changes in the physical traits, behaviors, and physiology of the colonist population of juncos at UCSD when compared to juncos from the nearby native range. Part of Ordinary Extraordinary Junco (Chapter 6).
Describes human activities' effects on earth. Examines how humans, industrialization, and technologies impact the environment, water cycle, and land use. Encourages better planning and management of resources.
What does it take to get a spacecraft to Mars? Scientists cover a few key things to remember when planning a trip to the Red Planet. Part of the “Mars in a Minute” series.
Anita Kalathil shows some of the latest chemistry projects taking place at Proctor & Gamble and what her typical day is like inside and outside the lab. Find out what it’s like to be a chemical engineer.
Earth's landscapes vary because there are different climatic zones that have unique, distinguishing conditions. One of these, the tropic zone, is divided into four more specific zones. The rainy tropics, wet-dry tropics, tropical and subtropical deserts, and tropical highlands are similar, yet different. Includes information on vegetation, animal life, human settlement, urban centers, and climatic conditions.
What does it take to estimate how much water a large city will need 25 years into the future? The chief of urban water conservation for the state of California explains the challenges of supplying water to a growing population of millions, much of which lives in the desert.
The mid-latitude and polar regions are two of earth's three climatic zones. The mid-latitude, or temperate, regions have definite seasonal changes in temperature and length of days and nights. Polar climates have extremely cold temperatures. Covers the climatic characteristics of the five subregions of the temperate and polar zones, noting also the vegetation, animal and human life, urban centers, and food crops.
Year after year massive fires continue to rip through the wildland-urban interface (WUI) in Colorado. Some scientists fear that the forests may not be able to recover due to a warming climate. Colorado University PhD student Monica Rother investigates post-fire ecosystems in an effort to predict what the Colorado Front Range might look like in a warmer, drier future. Part of the WildFire PIRE series.
Kate McMurtry is the branch chief of operations engineering at NASA’s Armstrong Flight Research Center. Selected as chief in 2014, McMurtry is responsible for planning, directing, and coordinating the technical and administrative functions for the branch. Prior to her current position, McMurtry acted as the branch chief and deputy branch chief for two years. McMurtry started her career in 2004 as a U.S. Air Force officer working in developmental engineering at Edwards Air Force Base, California, for the Airborne Laser Program. Part of the "Women@NASA" series.
Whether they arise from human causes or forces within planet Earth itself, natural disasters threaten life and civilization with what seems to be growing frequency. Studies troubling developments in marine, arctic, wetland, and urban environments while highlighting research opportunities that may help prevent future catastrophes. Coral reef decay, Everglades habitat loss, polar ice disappearance, and global warming are all analyzed. Looks at earthquake prediction, hurricane and tornado tracking, air pollution monitoring, tsunami warning systems, and the cleanup of toxic flood sediment in New Orleans.
Fieldwork is a critical part of geography, and involves a range of techniques. Two young commandos are on a fieldwork mission to research and report on the human impact in two geographical regions: one urban and one within a national park. Along the way they learn about preparation, collecting primary and secondary data, equipment, note taking, photographic recording, surveying and interviewing, and presenting findings. They also talk to park rangers who work in both areas and ultimately come to understand the importance of accurate, well-prepared fieldwork.
Already parts of the world suffer from lack of water, and with increasing demand it's expected to get worse. To better understand and predict drought, thirty universities are collaborating in a multidisciplinary effort called the Shale Hills Project. Among the studies, is field research following the life cycle of water along the Susquehanna River Basin. With support from the National Science Foundation, civil engineer Chris Duffy and his team at Penn State are tracking several aspects of rainfall to better understand the relationship between the flow of water, drought prone areas, and urban populations.
Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
