The Environmental Dimensions of the HIV/AIDS Pandemic: Natural Resource Dependence in Rural South Africa

Two important trends related to population dynamics and the environment are presently colliding to shape the sustainability of rural livelihoods in many poor nations. First, HIV/AIDS continues to dramatically shape mortality patterns, particularly in sub-Saharan Africa. Second, many regions are experiencing environmental degradation owing to numerous factors including social inequality and intense natural resource dependence.

Putting ecosystem services on the map

Natural ecosystems support human livelihoods and economies in numerous ways. These ecosystem services include carbon storage by forests, water regulation and purification by terrestrial systems, and crop pollination by wild bees. Recent syntheses, such as the Millennium Ecosystem Assessment and TEEB, have brought widespread attention to this powerful and intuitive concept.

Dendrohydrology in the Snake River Basin

Tree-ring samples collected near the Snake River headwaters were augmented with pre-existing tree-ring chronologies to create a 415-year reconstruction of upper Snake River streamflow, extending the short instrumental record and providing the first description of multicentury water supply variability in this river. Results indicate that the region’s early 21st century drought is severe even in the context of long-term climatic variability, and that the instrumental record is representative of low-flow individual years.

The Lower Mississippi as a Technological System

Beginning in the eighteenth century, settlers along the Lower Mississippi River used various kinds of technologies to contain the river's flows and protect the riparian land. These efforts accelerated in the nineteenth century, once the federal government became involved. Local levee districts worked with the federal government to maintain the river's depth and heighten levees. However, the devastation caused by the 1927 flood discredited dependence on levees, and Congress charged the U.S.

Are open ocean corals getting seasick? Forereef coral growth correlates negatively with ocean temperature in the western Caribbean Sea.

Rising ocean temperatures have negatively impacted the health of coral reefs and have led to higher rates of coral mortality. Despite this somber outlook, coral thermal stress response is highly variable, and this has fueled significant interest in discovering where the most thermally resilient corals reside to determine the factors that influence their susceptibility.
