Pre-Columbian deforestation as an amplifier of drought in Mesoamerica

Droughts in pre-Columbian Mesoamerica caused significant societal disruptions during the Late Classic and Post-Classic Periods. While the primary causes of these droughts are still debated, it has been speculated that they may be linked to extensive defore ...

The effects of land use and climate change on the carbon cycle of Europe over the past 500 years

Jed Oliver Kaplan, Kristen Marie Krumhardt

The long residence time of carbon in forests and soils means that both the current state and future behavior of the terrestrial biosphere are influenced by past variability in climate and anthropogenic land use. Over the last half-millennium, European terr ...

Organic functional groups in aerosol particles from burning and non-burning forest emissions at a high-elevation mountain site

Satoshi Takahama

Ambient particles collected on teflon filters at the Peak of Whistler Mountain, British Columbia (2182 ma.s.l.) during spring and summer 2009 were measured by Fourier transform infrared (FTIR) spectroscopy for organic functional groups (OFG). The project m ...

Tropical forest conservation: attitudes and preferences

Andrea Baranzini, Anne-Kathrin Faust

This paper applies contingent valuation to assess public awareness of tropical deforestation; to investigate the willingness to pay (WTP) to conserve tropical forests; and to determine the impact of the payment vehicle on the stated willingness to pay. Abo ...

Soil-vegetation patterns in secondary slash and burn successions in Central Menabe, Madagascar

Alexandre Buttler, Jean-Michel Gobat

Slash and burn agriculture is a traditional and predominant land use practice in Madagascar and its relevance in the context of forest preservation is significant. At the end of a cycle of culture, the fields become mostly weed covered and the soil fertili ...

The origin and fate of atmospheric moisture over continents

Bettina Schaefli

There has been a long debate on the extent to which precipitation relies on terrestrial evaporation (moisture recycling). In the past, most research focused on moisture recycling within a certain region only. This study makes use of new definitions of mois ...

Litter- and ecosystem-driven decomposition under elevated CO2 and enhanced N deposition in a Sphagnum peatland

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Jean-Michel Gobat, Andy Siegenthaler

Peatlands represent massive global C pools and sinks. Carbon accumulation depends on the ratio between net primary production and decomposition, both of which can change under projected increases of atmospheric CO2 and N deposition. The decomposition of li ...

Stratégies villageoises pour la gestion des paysages forestiers du Menabe Central, Madagascar

Clémence Dirac Ramohavelo

Introduction In order to reduce deforestation, the current attitude of conservation programmes and forest politics does no longer ban the local populations from the forests, because such measures present negative consequences for the communities. Today's t ...

The prehistoric and preindustrial deforestation of Europe

Jed Oliver Kaplan, Kristen Marie Krumhardt

Humans have transformed Europe’s landscapes since the establishment of the first agricultural societies in the mid-Holocene. The most important anthropogenic alteration of the natural environment was the clearing of forests to establish cropland and pastur ...

A game-theoretical model of deforestation in human-environment relationships

Antonio Rodrigues

We studied a two-person game regarding deforestation in human–environment relationships. Each landowner manages a single land parcel where the state of land-use is forested, agricultural, or abandoned. The landowner has two strategies available: forest con ...
