Distribution of wetlands in Argentina estimated from soil charts

Abstract

ABSTRACT. We generated a map of wetlands in Argentina from the digital edition of the National Soil Inventory made by the National Institute of Agricultural Technology (Instituto Nacional de Tecnología Agropecuaria, INTA). Potential wetland areas were extracted from the map after an exhaustive analysis of the database and reassignment of the soil classes, by taking into account 1) soil taxonomic classes; 2) constraining factors (waterlogging, flooding, drainage impairment); and 3) cartographic categories, including lakes, lagoons, marshes and salt lakes. Estimated wetland area is about 600,000 km 2 , representing 21.5% of the national territory; it increases to 23% when considering salt lakes and deepwater bodies, but their surface is underestimated in the INTA database. Finally, we analyzed the distribution and abundance of wetland areas from different eco-regions of Argentina, and compared our results with current global wetland databases.

“…Briefly, a ProxWet layer was generated using a vector model of wetlands distribution for Argentina (Kandus, Minotti, & Malvárez, ), which was rasterized and resampled to a resolution of 30 arc‐seconds. Following, a new raster was built which showed the Euclidean distance between each cell and the closest cell corresponding to a wetland.…”

Current state of knowledge regarding South America wetlands and their future under global climate change

“…Kandus et al (2008), using soil parameters, concluded that about 600,000 km 2 are wetlands, corresponding to 21.5% of the Argentinean territory. This percentage increases to 23% when permanent water bodies and saline areas are included.…”

“…Summaries exist, for instance, for the wetlands of Bolivia (Navarro and Maldonado 2002), Mamoré (Pouilly et al 2004), Patagonia (Collantes and Faggi 1999;Blanco and Balze 2004), the Orinoco River (Vasquez 1989;Weibezahn et al 1990;Lewis et al , 2000, Argentina (Malvárez and Bó 2004;Kandus et al 2008;Baigún et al 2008;Neiff 2001;Canevari et al 1999), the Amazon region (Sioli 1984;Salo et al 1986;Junk 1997a;Junk et al 2000Junk et al , 2010Padoch et al 1999;Kalliola et al 1993;Goulding 1980;Goulding et al1988Goulding et al , 1996Smith 1999;Melack and Forsberg 2001;Melack et al 2009), the Pantanal (Heckman 1998;Junk et al 2011a), the Paraná River floodplain (Paoli and Schreider 2000;Thomaz et al 2004;Iriondo et al 2007), and the ephemeral wetlands in South America (summarized in Deil 2005).…”

“…In the last years, important academic and governmental initiatives focused on proper characterization and classification of the regional South America continental wetlands (Kandus et al, 2008;Junk et al, 2014;Lasso et al, 2014).…”
