Education, gleaning and seagrass Wakatobi seagrass meadows are an essential resource base for local people contributing significantly to their welfare through the provision of fishing grounds, substrate for seaweed cultivation, nutrient cycling and, for the Bajo, a place to live. Despite the recognised importance of seagrass meadows, these habitats are suffering from increasing anthropogenic pressures. Recent Seagrass-Watch education and awareness raising held in Wakatobi, highlighted the importance of seagrass and the importance of minimising threats to ensure sustainable use of the resource. Clockwise from top: bringing in the gleaning 'catch', low tide gleaning typically a female activity; Halophila ovalis off Tomia Island ; Seagrass-Watch workshop on Hoga Island The destruction of seagrass meadows has been well documented and has wide ranging consequences, the most significant of which include a reduction of detritus production, which changes the fish community and alters the food web, beach erosion due to the loss of the binding roots, and loss of structural and biological diversity. Evidence from focus groups with the Pulo and Bajo communities indicates that significant areas of seagrass in the Wakatobi has already been destroyed or reduced in species and/or density. Few people in the Wakatobi are more aware of the significant threats to seagrass meadows than the Bajo, and for few people will the consequences of seagrass decline be more devastating. Fish are just one of many edible seagrass organisms. At low tide, nearly every accessible intertidal seagrass meadow in the Wakatobi is picked over by men, women and children gathering a major portion of their daily nutrition, and in many cases for fishing families this “gleaning” activity provides more essential nutrition than fishing itself. As each full moon approaches, the exposed intertidal zone at sunset becomes a significant fishing area, with numerous fishers and families collecting invertebrates, trapping fish stranded in tide pools, or bringing in their nets laden with fish after the tide has receded. Much of this fishing is subsistence and communitybased activity, but it also includes small family fishing collectives earning a basic living selling excess catch. In many locations it involves the whole family, including small children, and as a result exists as a social and recreational activity. Therefore, not only are these threats to seagrass threatening an important resource, they are also threatening a way of life. MARCH 2013 25
