摘要
The prospects and challenges facing eight small water impounding projects(SWIPs)in Talugtog,Nueva Ecija,an upland municipality located in Central Luzon,Philippines were evaluated using rapid appraisal and documentation of projects,interview of farmers and local officials,and a review of related studies undertaken on the same project sites.The challenges include the deterioration of structural facilities,inactive farmers associations,watershed degradation,and climate change.It also aims to evaluate improvement and innovation in the future implementation of SWIPs as rainwater harvesting facilities.The site was selected because it has the largest number of SWIPs established as one of the coping strategies during the 1997-1998 severe El Nino.Because of its location,it has no major irrigation systems and relies only on local rainwater storage facilities.The study involves 8 SWIPs established in two clusters(i.e.,5 and 3 SWIPs in a watershed)as rainwater conservation and management facilities.Results indicated these clusters of SWIPs offer multiple benefits in terms of supplemental irrigation,inland fish production,and water for domestic purposes and livestock production.They also serve as strategic small-scale upland structures that enhance recharging of groundwater,prevent flooding,and provide value-adding activities such as recreation,soil and water conservation,and environmental benefits.Previous studies also identified their benefits at the farm and community levels as conserved rainwater through storage in SWIPs is translated into more economic uses.However,some SWIPs are confronted with various challenges;deterioration of structural facilities,inactive farmer associations,unabated watershed degradation,and threats of climate change.These are seriously affecting the overall performance of SWIPs.Immediate actions should include the strengthening of small water impounding system associations(SWISA),repair and climate-proofing of structural facilities through the(SWISA)themselves,and watershed protection and management through the adoption of appropriate soil and water conservation measures.
