El aprovechamiento sostenible de los humedales que existen en áreas naturales protegidas (ANP) generó beneficios económicos por 33 millones de soles en el 2015, a través de proyectos productivos y de ecoturismo, destacó el Servicio Nacional de Áreas Naturales Protegidas por el Estado (Sernanp). Al haberse celebrado el pasado 2 de febrero el Día Mundial de los Humedales, la especialista del Sernanp Gloria Rojas dio a conocer que las ANP donde se registran experiencias de desarrollo sostenible son las Reservas Nacionales de...

A warming climate is likely to drive species to higher, cooler altitudes. A new study highlights a less obvious, yet crucial way in which their new habitat could differ from the one they leave behind. Mountains are home to many living species, with biodiversity typically peaking at mid-altitudes. Scientists have long struggled to explain why this is the case, invoking factors such as low temperatures at high elevations or human disturbance further down. According to new research, mid-altitudes host the largest number of species because the size and the connectedness of similar habitats are...

Harvestmen— a spider-like arachnid— are among the first creatures to inhabit land in the wake of glacier retreat, according to a recent study by Sigmund Hågvar and Daniel Flø in the Norwegian Journal of Entomology. The land where glaciers have recently melted is an ideal habitat for creepy-crawlies including spiders, beetles, and other invertebrates. Perhaps surprisingly, these predators are often the first species found on this new land, before herbivores and even plants, although classical theories in ecology state that it should be the other way around. The...

Mountain glaciers are significant water storage mechanisms, but they are rapidly declining in extent worldwide. A new study shows that in the Pacific Northwest, glaciers in British Columbia and Alberta are projected to decline by around 70 percent relative to their 2005 levels by 2100. Expanded simulations predict mountain glaciers in inland regions will be hardest hit, contributing to increased sea level rise and reduced water in many regions of Canada and downstream in the United States. Such decreases in banked water supply will greatly impact water quality and availability, as well as...

Forests are being converted into agricultural land throughout the tropics, from Borneo to the Congo Basin. But this process – called agrarian change – can bring communities benefits as well as consequences. Questions about the benefits and trade-offs of agrarian transitions are too often reduced into a simple debate over how best to increase agricultural production while minimizing deforestation. “When you’re looking at patterns of agrarian change you need to consider all kinds of other things, not just agricultural production, but livelihoods, diets, ecosystem...

Two recent studies offer complementary accounts of the ways that glacier retreat and other impacts of climate change have displaced indigenous people from their communities in the Peruvian Andes. One describes the people who have left as refugees, the other as migrants. Both emphasize the seriousness and apparent irreversibility of this large population movement Teófilo Altamirano’s book,Environmental Refugees: Climate Change and Involuntary Migration, draws on methods and concepts from anthropology to explore displacement from a glacier region in central Peru. It links...

La Corte Constitucional decidirá si artículos del Plan Nacional de Desarrollo, incluido el que permite la minería en páramos, van en contra de la Constitución. Después de más de seis meses de que el presidente de la República, Juan Manuel Santos, sancionara el Plan Nacional de Desarrollo (PND) 2014-2018, la sala plena de la Corte Constitucional decidirá este miércoles una de las dos demandas por inconstitucionalidad que cursan contra esa ley, que fue interpuesta por el Polo Democrático y está a...

A new Yale-led study offers a new conceptual framework for understanding the biogeochemistry of watersheds. The framework combines hydrologic and biogeochemical theory to test well established concepts in watershed ecology.   The paper, published in the journal Ecology, suggests that heavy weather events, though infrequent, cause an inordinate amount of organic material to bypass headwater systems, pushing them downstream into larger rivers, coastal waters, and inland basins.   This phenomenon can have profound ecological implications on the quality of water systems...
