        Gezira  scheme (0.88 million  hectare) has  recently  showed  a

low  level   of  economical   efficiency. The government  introduced

the  policy  or  water  users'  associations  (WLJAs)  in  2005  to  be

responsible   for   water.  management    and    crop    choices.  The

objective   of   this   study   is   to   the   performance  of WUAs   in

Gezira  Scheme  using  selected  remotely sensed -  based  indicators.

Images  were  collected  for  three   seasons  2004/2005, 2005/2006

and  2011/2012,  representing  the  period  prior  to  the  WUA,  the

start  season  of   the  policy  and  a validation  season, respectively.

Based  on  the  Mann - kendall  test  the  cultivated  area  showed a

significant  decreasing  trend  (P = 0.002) for  the  last  thirty  years

with   a current   cropping   intensity  of   0.48. The   study  showed

mixed    results,  The  adoption  of   WUAs   policy   resulted  in  no

significant    improvement   (P = 0.29)   in    the    monthly   overall

consumed   ratio,  indicating   the   poor   performance   of   WUAs

policy.   The  scheme  water  depletion  fraction  (DE) was found poor

(less    than  1%)    throughout    the    studied    seasons  due   to   high

evaporation    losses.  Relatively,   the   adoption  of    WUAs   policy

however  in  the  second  season  is  significantly  increased (P = 0.0)

the   DF   from   0.07%    to    0. I %   because  of  the improvement in

irrigation   adequacy,  This   improvement   was  not   sustained  since

the   DF   was   decreased   to   0.05%  in the validation season. On the

basis   of   standardized   gross   value   of   production,    the   WUAs

policy   succeeded   ill   increasing   fanners'   income by widened crop

choices.  The  WUAs   policy   is   a good  turning point; however  its

adoption  should  be  followed  by  irrigation  canal  maintenance  and

capacity building programs.
