Syr darya 5

  1. 1. Kyrgyzstan   Tajikistan   Kazakhstan   GROUNDWATER  MANAGEMENT  IN  THE  SYR   DARYA  TRANSBOUNDARY  BASIN   MANAGING  THE  SUBSURFACE  SPACE   by   ANDREA  MERLA   PROJECT  PREPARATION  PHASE   INCEPTION  MEETING   Paris  –  February  3-­‐4,  2014  
  2. 2. Use  of  the  subsurface  has  become  steadily  more   intensive,  both  by  the  intensificaRon  of  convenRonal   uses  of  the  subsurface  and  its  resources,  and  by  the   emergence  of  relaRvely  new,  non-­‐convenRonal  uses.   The  first  category  includes  groundwater  abstracRon  and   the  extracRon  of  minerals  and  hydrocarbons.  Using  the   subsurface  for  developing  geothermal  energy,  for   systemaRc  disposal  of  hazardous  waste  or  for  various   injecRon/recovery  applicaRons  started  more  recently.   Subsurface  construcRng  may  be  a  convenRonal  acRvity,   but  its  quickly  increasing  intensity  in  numerous  areas  is   unprecedented.    Likewise,  groundwater  abstracRon  is  in   some  areas  shi]ing  to  aquifers  at  greater  depths  than   ever  before.    
  3. 3. Category   Type  of  AcRvity   DistribuRon   Pushing  the  Aquifer   fronRer   Groundwater  withdrawal  from  deeper   Sedimentary  basins   aquifers  (>500m)   Subsurface  Energy   Development   Oil  &  Gas     Geothermal  energy   Major  sedimentary  Basins     Thermally  anomalous  areas     Disposal/storage  of   Hazardous  wastes   Deep  Well  InjecRon   Areas  associated  with  oil  &   gas  industry   InjecRon  and   recovery   SoluRon  mining   ReinjecRon  spent  geothermal  fluids   Fracking   Carbon  Capture  and  SequestraRon   Mining  areas   Geothermal  fields   Shale  gas  formaRons   Tests  in  Canada,  Algeria,  N.   Sea   ConstrucRons   Pipelines,  sewerage,  cables   Tunnels,  railways   Car  parks  etc.   General,  Urban  Areas   Aquifer  Recharge   Managed  Aquifer  Recharge   Aquifers  Storage  and  Recovery   General

  6. 6. TIBET   SINGAPORE  
  7. 7. Decision-­‐makers  and  stakeholders  need   to  be  aware  of  the  many  potenRal  uses   and  the  current  uses  of  the  subsurface   and  subsurface  resources  in  the  area  of   their  concern.     Furthermore,  they  need  to  have  a   reliable  picture  of  the  benefits,  costs   and  risks  of  the  individual  subsurface   acRviRes  (in  comparison  with  those  of   non-­‐subsurface  alternaRves).   UncertainRes  exist  on  the  assumed  properRes   and  potenRal  of  the  underground.  Many   processes  that  produce  change  in  the   subsurface  are  virtually  irreversible,  on  a   human  Rme  scale.       Those  responsible  for  groundwater   resources  management  should   make  sure  that  all  new  iniRaRves   for  subsurface  acRviRes  are  known   to  them  in  Rme
