Critical distances: Comparing measures of spatial accessibility in the riverine landscapes of Peruvian Amazonia

Evaluating the Impact of Distance Measures on Deforestation Simulations in the Fluvial Landscapes of Amazonia

“…There are very few roads in Loreto but the region is well connected by branching and highly meandering rivers that form the backbone of regional transportation. As a majority of transportation within the region is fluvial, the dynamic river network shapes patterns of accessibility between the regional core and the hinterland (Salonen et al 2012). Meandering channels are the dominant river channel type in the area (Puhakka et al 1992), and the high sinuosity of the channels implies that travel routes may end up being much longer than straight-line distances (Toivonen et al 2007).…”

Floodplain fish communities in river systems in Bolivia: Current knowledge and addressing future research challenges

“…Despite its low population density, current deforestation rates in Bolivia are 200,000 ha per year. Current estimates indicate that deforestation rates will increase due to mechanized agriculture, cattle ranching, small-scale agriculture supported by strong international investment, increased demand nationally as a result of population growth, road expansion and institutional weaknesses (Steininger et al 2001, Salonen et al 2011, Müller et al 2014. However the impacts of on-going deforestation on the aquatic environments of Bolivia have received little attention.…”

“…Fish constitute an important part in the diet of indigenous groups, especially during the rainy season, when large areas are flooded and human populations are isolated (Pouilly et al 2004b). Rivers are also important corridors for the exchange and sale of agricultural and nontimber products and a key source for financial income (Salonen et al 2011). Fish diversity loss will undoubtedly have an adverse effect on the survival of local communities; therefore any conservation approach must rely on local knowledge and the participation of local communities to be effective (Reinert & Winter 2002).…”

A geographical methodology for assessing nodality of a road network. Case study on the western Moldavia

“…2011 for an overview). Using metric distances seems obsolete since the new GIS technologies makes possible to calculate, with a relatively high precision, the temporal distances (Berke and Shi 2009;Salonen et al;Shaw 2006) or the economic ones (cf. Combes and Lafourcade 2005).…”
