“…Land-use and landcover changes are so pervasive that, when aggregated globally, they signifcantly afect key aspects of the functons of the Earth's systems. Land-use and land-cover changes directly impact biotc diversity worldwide (Sala et al, 2000); contribute to local and regional climate change (Chase, Pielke, Kitel, Nemani & Running, 1999) as well as to global climate warming (Houghton, Hackler & Lawrence, 1999); are the primary source of soil degradaton (Tolba & El-Kholy, 1992); and, by altering ecosystem services, afect the ability of biological systems to support human needs (Vitousek, Mooney, Lubchenco & Melillo, 1997). Such changes also determine, in part, the vulnerability of places and people to climatc, economic or socio-politcal perturbatons (Kasperson, Kasperson & Turner, 1995).…”

A majority of secondary science teachers are found to include the topic of climate change in their courses. However, teachers informally and sporadically discuss climate change and students rarely understand the underlying scientfc concepts. The project team developed an innovatve pedagogical approach, in which teachers and students learn climate change concepts by analyzing Natonal Aeronautcs and Space Administraton (NASA) global data collected through satellites and by imitatng the NASA data collecton process through NASA Airborne Earth Research Observaton Kites And Tethered Systems (AEROKATS), a kite-borne remote sensing system. Besides AEROKATS, other major components of this system include a web-collecton of NASA and remote sensing data and related educatonal resources, project-based learning for teacher professional development, teacher and student feld trips, iOS devices, smart feld data collector apps, portable weather statons, probeware, and a virtual teacher collaboratory supported with a GIS-enabled mapping portal. Three sets of research instruments, the NASA Long-Term Experience-Educator End of Event Survey, the Teacher End of Project Survey, and the pre-and-post-Investgatng Climate Change and Remote Sensing (ICCARS) project student exams, are adapted to study the pedagogical impacts of the NASA AEROKATS remote sensing system. These fndings confrm that climate change educaton is more efectve when both teachers and students actvely partcipate in authentc scientfc inquiry by collectng and analyzing remote sensing data, developing hypotheses, designing experiments, sharing fndings, and discussing results.

The objective of this study was to quantify the impacts of land use/land cover (LULC) change on the hydrology of the Jedeb, an agricultural dominated mesoscale catchment, in the Abay/Upper Blue Nile basin, Ethiopia. Two methods have been used. First, the trends of certain daily flow variability parameters were evaluated to detect statistical significance of the change of the hydrologic response. Second, a conceptual monthly hydrological model was used to detect changes in the model parameters over different periods to infer LULC change. The results from the statistical analysis of the daily flows between 1973 and 2010 reveal a significant change in the response of the catchment. Peak flow is enhanced, i.e. response appears to be flashier. There is a significant increase in the rise and fall rates of the flow hydrograph, as well as the number of low‐flow pulses below a threshold level. The discharge pulses show a declining duration with time. The model result depicts a change in model parameters over different periods, which could be attributed to an LULC change. The model parameters representing soil moisture conditions indicated a gradual decreasing trend, implying limited storage capacity likely attributed to increasing agricultural farming practices in the catchment. This resulted in more surface runoff and less infiltration into the soil layers. The results of the monthly flow duration curve analysis indicated large changes of the flow regime. The high flow has increased by 45% between the 1990s and 2000s, whereas the reduction in low flows was larger: a 15% decrease between 1970s and 1980s, 39% between 1980s and 1990s and up to 71% between 1990s and 2000s. These results, could guide informed catchment management practices to reduce surface runoff and augment soil moisture level in the Jedeb catchment. Copyright © 2013 John Wiley & Sons, Ltd.
