       5               decomposition methods assume the simultaneous occurrence of various trends, the outcome


                       being sensitive to the sequence chosen. A number of conclusions can be drawn about the
                       applicability and utility of these methods. Several methods to evaluate changes and measures
                       exist. All give different results and one is not better than the other, so it is very important that
                       when presenting the results the method chosen is also explained.
            9-12 December, 2013  6.8 The policy narrative sheet – summarizing policy failures and successes








                  The final step in the policy analysis approach is to develop a policy narrative that summarizes the results
                  of the policy analysis (steps A-D and the analysis of relative policy impacts, if known). The purpose is to
                  develop credible statements regarding the adequacy of past and current policy responses for restoring
                  and maintaining the state of the environment, and facilitating adaptation to impacts.

                  The policy narrative sheet should have components similar to those illustrated in Table 13

                      Groundwater Protection in Wadi Ma'awil,  Barka town,  Oman
                      (Al-Shoukri,. and Abahussain,  2008).



                      Introduction
                      Wadi Ma'awil, in coastal part of Al Batinah Region northern Oman, groundwater is the

                      main source for water supply. Unfortunately, during the last 30 years this resource has been
                      deteriorated in terms of quality and quantity

                      Population growth, economic development, urbanization expansion beside the frequent
                      drought periods has been associated with increasing water demands. Many anthropogenic
                      activities such as agricultural and inefficient and inadequate waste management are threatening

                      groundwater quantity and quality. The heavy reliance on groundwater has caused lowering
                      of groundwater levels and drying of Aflaj and springs in the interior regions, and causing
                      seawater intrusion in the coastal areas of Oman. The cost of water contamination and its
