View Resource Agapostemon sweat bee

As global food demand increases, farmers are increasingly relying on single, managed bee species (often honey bees) to pollinate their crops. However, honey bees are not the best pollinators for all crops, and honey bee colonies have recently been experiencing health problems, notably colony collapse disorder. Recent research has shown that promoting a diversity of wild insect pollinators – suc...

View Resource Growing Plants for Fuel: Predicting Effects on Water, Soil, and the Atmosphere

This report looks at both the grain and cellulose-based “bioenergy landscapes” and review what is known about their biogeochemical impacts. This report will also explore the complexity of factors involved in calculating the benefits of particular cropping systems. In evaluating the benefits, the use of mathematics as a method to projecting performance and environmental outcomes is explained as...

View Resource Melting Glaciers on Mt. Kilimanjaro

This pair of Landsat images shows the rapid loss of the fabled glaciers and snowfields crowning Mt. Kilimanjaro between 1993 and 2000. With the snow and ice nearly gone, the volcano's crater is visible on the later image. The snowfields were first measured in 1912, and by 2009, 86% of that original extent was gone. Melting has become much more rapid in the last decade. While multiple factors...

View Resource To Plant, or Not to Plant? Regulating Invasive Plant Species in the Mid-Atlantic States: A Social-Ecological System Case Study

As invasive plant species spread across landscapes, costs of their economic and environmental impacts have sparked interest in regulating their sale and transport. Laws now prohibit the sale and movement of some species. State and local governments are drafting regulations that will affect horticulture, plant nurseries, and options for landscape design. Awareness of invasive plant species is...

View Resource Life Cycle Analysis and Assessment of Crop Production Methods

Students use their ecological knowledge of soil processes, energy, water systems, and human interactions to compare the environmental impact of food production. Each group of 3-4 students develop life cycle analyses (LCA) for a single crop grown under different scenarios. As individuals, students are responsible for developing two LCA for that crop, and then together in their groups, they compile...
