Power, knowledge and political ecology in the third world: a review
Progress in Physical Geography - Tập 22 Số 1 - Trang 79-94 - 1998
Political ecology examines the political dynamics surrounding material and
discursive struggles over the environment in the third world. The role of
unequal power relations in constituting a politicized environment is a central
theme. Particular attention is given to the ways in which conflict over access
to environmental resources is linked to systems of political and economic
control first elabo...
Remote sensing methods in medium spatial resolution satellite data land cover classification of large areas
Progress in Physical Geography - Tập 26 Số 2 - Trang 173-205 - 2002
Numerous large-area, multiple image-based, multiple sensor land cover mapping
programs exist or have been proposed, often within the context of national
forest monitoring, mapping and modelling initiatives, worldwide. Common
methodological steps have been identified that include data acquisition and
preprocessing, map legend development, classification approach, stratification,
incorporation of an...
Quaternary glacial history of the Mediterranean mountains
Progress in Physical Geography - Tập 30 Số 3 - Trang 334-364 - 2006
Glacial and periglacial landforms are widespread in the mountains of the
Mediterranean region. The evidence for glacial and periglacial activity has been
studied for over 120 years and it is possible to identify three phases of
development in this area of research. First, a pioneer phase characterized by
initial descriptive observations of glacial landforms; second, a mapping phase
whereby the det...
Pathways for climate change effects on fire: Models, data, and uncertainties
Progress in Physical Geography - Tập 35 Số 3 - Trang 393-407 - 2011
Fire is a global process affecting both the biosphere and the atmosphere. As a
result, measuring rates of change in wildland fire and understanding the
mechanisms responsible for such changes are important research goals. A large
body of modeling studies projects increases in wildfire activity in future
decades, but few empirical studies have documented change in modern fire
regimes. Identifying g...
Economic valuation and the commodification of ecosystem services
Progress in Physical Geography - Tập 35 Số 5 - Trang 613-628 - 2011
In the last decade a growing number of environmental scientists have advocated
economic valuation of ecosystem services as a pragmatic short-term strategy to
communicate the value of biodiversity in a language that reflects dominant
political and economic views. This paper revisits the controversy on economic
valuation of ecosystem services in the light of two aspects that are often
neglected in o...
Last Glacial Maximum conditions in southern Africa
Progress in Physical Geography - Tập 38 Số 5 - Trang 519-542 - 2014
The Last Glacial Maximum (LGM) (21±2 ka) is an important period for which to
understand past climatic and environmental conditions. In particular it is a key
time-slice for evaluating the performance of numerical climate model simulations
of glacial palaeoclimates using palaeoenvironmental data sets. However, our
palaeoenvironmental data sets and reconstructions of climatic conditions at the
LGM a...
Sorting out river channel patterns
Progress in Physical Geography - Tập 34 Số 3 - Trang 287-326 - 2010
Rivers self-organize their pattern/planform through feedbacks between bars,
channels, floodplain and vegetation, which emerge as a result of the basic
spatial sorting process of wash load sediment and bed sediment. The balance
between floodplain formation and destruction determines the width and pattern of
channels. Floodplain structure affects the style and rate of channel avulsion
once aggradati...
Complex response of river channel morphology subsequent to reservoir construction
Progress in Physical Geography - Tập 3 Số 3 - Trang 329-362 - 1979
Combustion in tropical biomass fires: a critical review
Progress in Physical Geography - Tập 24 Số 3 - Trang 355-377 - 2000
Despite the publication of a number of recent books, mainly edited compilations,
on both fire ecology in general and, more specifically, fire ecology in the
tropics, it remains difficult to obtain accessible overviews of many aspects of
the subject. This is particularly so with regard to tropical biomass fires. The
review presented here attempts to fill this gap with regard to the subjects of
igni...
