Advances in Geographical and Environmental Sciences R.B. Singh Pawel Prokop Editors Environmental Geography of South Asia Contributions Toward a Future Earth Initiative Advances in Geographical and Environmental Sciences Serieseditor Dr.R.B.Singh AIMSANDSCOPE Advances in Geographical and Environmental Sciences synthesizes series diagnostigationandprognostication ofearthenvironment,incorporating challeng- ing interactive areas within ecological envelope of geosphere, biosphere, hydro- sphere, atmosphere and cryosphere. It deals with land use land cover change (LUCC), urbanization, energy flux, land-ocean fluxes, climate, food security, ecohydrology, biodiversity, natural hazards and disasters, human health and their mutualinteractionandfeedbackmechanisminordertocontributetowardssustain- able future. The geosciences methods range from traditional field techniques and conventional data collection, use of remote sensing and geographical information system,computeraidedtechniquetoadvancegeostatisticalanddynamicmodeling. Theseriesintegratepast,presentandfutureofgeosphericattributesincorporat- ing biophysical and human dimensions in spatio-temporal perspectives. The geosciences, encompassing land-ocean-atmosphere interaction is considered as a vital component in the context of environmental issues, especially in observation and prediction of air and water pollution, global warming and urban heat islands. It is important to communicate the advances in geosciences to increase resilience of society through capacity building for mitigating the impact of natural hazards and disasters.Sustainability ofhumansociety dependsstronglyonthe earth envi- ronment, and thus the development of geosciences is critical for a better under- standingofourlivingenvironment,anditssustainabledevelopment.

The region comprises the Himalayas, the alluvial plains of the Indus and Ganga–Brahmaputrariversystems,andtheuplandsoftheDeccanPlateauinIndia, togetherwith the central hill massifofSri Lanka. The region is surrounded inthe southbythreemarineecosystems:theArabianSea,theIndianOcean,andtheBay ofBengal.Theseasonalalterationofatmosphericflowpatternsbetweenlandmass and sea, associated with the monsoons, frequently cause severe floods, droughts, andmassmovementsoverlargeareasofSouthAsia.Althoughtheregionoccupies only4.8%oftheworld’stotallandarea,ithasapopulationof1.67billion(23.8% of the world’s total), growing at the rate of 1.8 % per annum. Thus, vulnerable natural features of environment combined with the high population density, rapid economicdevelopment, andcorresponding competition for agriculturalandurban landaswellaswaterresourceshaveenormoussocietalconsequences.Theeffects ofthesenatural–humaninteractionsarenotlimitedonlytotheSouthAsianregion buthaveanimpactonenvironmentandsocietyonaglobalscale.

TheconferencewasorganizedbytheInstituteofGeographyofthePolishAcademy of Sciences and seven other geographical research institutions in Poland. A few invited papers are also included here to cover all dimensions of environmental geography. The book consists of 19 chapters that contribute to better recognition andunderstandingofrapidcivilizationdevelopmentinthecontextofbothregional andglobalenvironmentalchanges.Thusthisvolumeintegratesattributesrelatingthe past, present, and future of South Asia broadly based on biophysical and human dimensionsinspatio-temporalperspectives.Climatechange,spacebornemonitoring, andmitigationofnaturalhazardsareconsideredvitalcomponentsinthecontextof v vi Preface environmental issues, especially in observation and prediction of extreme climate events,land-usechangesleadingtolanddegradation,andurbanization. Thecontri- butionsrangefromtraditionalfieldtechniquesandconventionaldatacollectiontothe useofremotesensingandgeographicinformationsystems. We hope that the present volume will deepen the awareness of numerous changesinbothnaturalandhumansystemsthatsignificantlyinfluencethepresent and future well-being of South Asian societies in general. The increasing impor- tance of interdisciplinary research is the best tool to combine the different approacheswithknowledgeandtechniquesfromparticularbranchesofgeography. We believe that the book will also be beneficial to people in other fields such as geology, ecology, environmental sciences, tourism, disaster management, and urban studies. We hope, that this volume stimulates further research and that these topics will continue to be focal points for future geographical research at global,regional,andnationallevels. We would like to thank the IGU officers and the members of the Conference Organizing Committee. We appreciate the hard work of the contributors and referees of the papers both for their time and their early responses. We are also thankful to Dr. Ajay Kumar for providing assistance. We wish to express our deepest thanks to Ms. Taeko Sato from Springer Japan for all the help provided inthepublicationprocessofthisbook.
