The main reason for studying Deltas is their potential vulnerability to climate change and sea level rise, which generates important challenges for livelihoods. We provide insights into the current socioeconomic and biophysical states of the Volta Delta (Ghana), Mahanadi Delta (India) and Ganges-Brahmaputra-Meghna (India and Bangladesh). Hybrid methods of input-output (IO) construction are used to develop environmentally extended IO models for comparing the economic characteristics of these delta regions with the rest of the country. The main sources of data for regionalization were country level census data, statistics and economic surveys and data on consumption, trade, agricultural production and fishing harvests. The Leontief demand-driven model is used to analyze land use in the agricultural sector of the Delta and to track the links with final demand. In addition, the Hypothetical Extraction Method is used to evaluate the importance of the hypothetical disappearance of a sector (e.g., agriculture). The results show that, in the case of the Indian deltas, more than 60% of the cropland and pasture land is devoted to satisfying demands from regions outside the delta. While in the case of the Bangladeshi and Ghanaian deltas, close to 70% of the area harvested is linked to internal demand. The results also indicate that the services, trade and transportation sectors represent 50% of the GDP in the deltas. Still, agriculture, an activity directly exposed to climate change, plays a relevant role in the deltas'' economies-we have estimated that the complete disappearance of this activity would entail GDP losses ranging from 18 to 32%. 000070950 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000070950 590__ $$a2.592$$b2018 000070950 591__ $$aENVIRONMENTAL SCIENCES$$b105 / 250 = 0.42$$c2018$$dQ2$$eT2 000070950 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b3 / 6 = 0.5$$c2018$$dQ2$$eT2 000070950 591__ $$aENVIRONMENTAL STUDIES$$b44 / 116 = 0.379$$c2018$$dQ2$$eT2 000070950 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b20 / 35 = 0.571$$c2018$$dQ3$$eT2 000070950 592__ $$a0.549$$b2018 000070950 593__ $$aGeography, Planning and Development$$c2018$$dQ2 000070950 593__ $$aRenewable Energy, Sustainability and the Environment$$c2018$$dQ2 000070950 593__ $$aManagement, Monitoring, Policy and Law$$c2018$$dQ2 000070950 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000070950 700__ $$aArto, I. 000070950 700__ $$aHazra, S. 000070950 700__ $$aBhattacharya, R.N. 000070950 700__ $$aAdjei, P.O.-W. 000070950 700__ $$aOfori-Danson, P.K. 000070950 700__ $$aAsenso, J.K. 000070950 700__ $$aAmponsah, S.K. 000070950 700__ $$aKhondker, B. 000070950 700__ $$aRaihan, S. 000070950 700__ $$aHossen, Z. 000070950 773__ $$g10, 3 (2018), 893 [22 pp]$$pSustainability (Basel)$$tSustainability (Switzerland)$$x2071-1050 000070950 8564_ $$s697241$$uhttps://zaguan.unizar.es/record/70950/files/texto_completo.pdf$$yVersión publicada 000070950 8564_ $$s108000$$uhttps://zaguan.unizar.es/record/70950/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000070950 909CO $$ooai:zaguan.unizar.es:70950$$particulos$$pdriver 000070950 951__ $$a2020-01-13-14:54:15 000070950 980__ $$aARTICLE
