Chapter  9:  Case  studies  in  Ta’izz       9.1    A:  Context  and  contextual  changes   Ta'izz  is  facing  a  serious  and  complex  water  problem.  Competition  between  urban  and  rural  water  uses  is   ever  present.  Agriculture  continues  to  draw  a  large  amount  of  groundwater  for  irrigation,  urban  population   grows,  industrial  expansion  takes  place  and  total  groundwater  demand  has  increased  sharply  (Van  der  Gun   &   Riaz,   2004).   This   competitive   approach   of   abstraction   by   the   farmers   and   water   supply   agencies   has   already   led   to   rapid   depletion   of   aquifers,   depriving   farmers   of   their   means   of   livelihood   and   has   in   turn   created  an  environment  of  conflict  (Al-­‐Shaybani  et  al.,  2005).     The   crisis   in   the   Ta'izz   area   represents   a   case   of   total   water   management   failure.   The   failure   occurred   because   of   the   absence   of   feedback   and   support   processes   between   the   Government   and   the   local   societies   throughout   the   implementation   of   all   water   strategies   adopted   by   the   Government   (Mohieldeen,   1999).  To  understand  the  reason  for  the  conflicts  concerning  water,  an  overall  description  of  the  area  that   includes   the   physical   causes   of   the   water   crisis,   the   main   institutions   and   stakeholders   and   socio-­‐economic   situation   of   the   area   is   necessary.   Thereafter,   an   overview   of   the   main   water   conflicts   in   the   past,   the   effects  of  unreliable  water  supply  in  Ta'izz  city  and  some  examples  of  cooperation  will  be  provided.     9.1.1    Physical  profile   The   Ta'izz   region   is   in   the   upper   part   of   Wadi   Rasyan   catchment   in   the   south-­‐western   Yemen   Mountains,   it   extends   between   the   latitudes   13º   34'   and   13º   47'   North,   and   the   longitudes   43º   48'   and   44º   12'   East.   (Farag  et  al.,  2013).  The  region  is  located  within  a  low  plateau  that  lies  in  an  east-­‐west  faulted  sink  25km   wide.  The  sink  descends  from  1500m  in  the  east  to  less  than  900m  in  the  west  in  a  series  of  step-­‐faulted   blocks  of  stratified  volcanics,  which  dip  to  the  east  or  northeast.  The  eastern  edge  of  the  area  is  covered  by   a  flat  loess  covered  plateau,  forming  the  surface-­‐water  divide  between  the  Red  Sea  and  the  Indian  Ocean   (UN/DDSMS,  1997).       Water  resources  of  the  region  are  heavily  dependent  on  rainfall,  which  varies  substantially  from  one  sub-­‐ area   to   another   within   the   same   catchment.   While   the   mean   annual   precipitation   for   the   whole   area   is   around  568  mm,  the  highlands  receive  a  greater  amount  of  800mm.  The  pattern  of  rainfall  in  the  region  is   bimodal  with  one  peak  occurring  in  April/May  and  the  other  in  August/September.  (Van
