Territorialidades, re-territorializaciones y resistencias en el Delta

A partir de la década del 70` se marca un quiebre del modelo productivo industrial, así como de las relaciones sociales y económico organizativas producto de la misma. En este marco se produce un cambio en las estructuras productivas, relacionadas con la desarticulación del Estado benefactor, en conjunción con un imperio del mercado y la reconfiguración de los modos de vida existentes cristalizados en el espacio. En este contexto, este artículo intentará abordar un proceso socio-territorial de toma ilegal de tierras por parte de la empresa Colony Park S.A., en el delta que será el puntapié inicial para analizar procesos conflictivos respecto a sus habitantes tradicionales en torno al cambio en su modo de vida, producción y relaciones sociales al consolidarse una gentrificación (Castells, 1994) y un cambio del uso del suelo tradicional a favor de los intereses del Capital. Además, analizaremos la resistencia personificada en la conjunción de los habitantes tradicionales, los vecinos y el Estado municipal. La relevancia está en analizar nuevos conflictos socio-territoriales donde la toma de tierras es producida en torno a la utilización mercantil de las mismas, y que termina generando procesos de resistencia innovadores e impensados en la sociedad industrial

Organic carbon and total nitrogen stocks in soils of the Lena River Delta

The Lena River Delta, which is the largest delta in the Arctic, extends over an area of 32 000 km**2 and likely holds more than half of the entire soil organic carbon (SOC) mass stored in the seven major deltas in the northern permafrost regions. The geomorphic units of the Lena River Delta which were formed by true deltaic sedimentation processes are a Holocene river terrace and the active floodplains. Their mean SOC stocks for the upper 1 m of soils were estimated at 29 kg/m**2 ± 10 kg/m**2 and at 14 kg/m**2 ± 7 kg/m**2, respectively. For the depth of 1 m, the total SOC pool of the Holocene river terrace was estimated at 121 Tg ± 43 Tg, and the SOC pool of the active floodplains was estimated at 120 Tg ± 66 Tg. The mass of SOC stored within the observed seasonally thawed active layer was estimated at about 127 Tg assuming an average maximum active layer depth of 50 cm. The SOC mass which is stored in the perennially frozen ground at the increment 50-100 cm soil depth, which is currently excluded from intense biogeochemical exchange with the atmosphere, was estimated at 113 Tg. The mean nitrogen (N) stocks for the upper 1 m of soils were estimated at 1.2 kg/m**2 ± 0.4 kg/m**2 for the Holocene river terrace and at 0.9 kg/m**2 ± 0.4 kg/m**2 for the active floodplain levels, respectively. For the depth of 1 m, the total N pool of the river terrace was estimated at 4.8 Tg ± 1.5 Tg, and the total N pool of the floodplains was estimated at 7.7 Tg ± 3.6 Tg. Considering the projections for deepening of the seasonally thawed active layer up to 120 cm in the Lena River Delta region within the 21st century, these large carbon and nitrogen stocks could become increasingly available for decomposition and mineralization processes.
