Estimating Socio-Cultural Services of Coastal Wetlands: A Case of Negombo Lagoon in Sri Lanka

Knowledge on social and cultural systems is essential for comprehensive understanding of ecosystem changes, monitoring biodiversity, development and implementation of resource management strategies. Social values of coastal landscapes reveal the attributes of locations and their relative importance for people. Aim of the study was to evaluate the cultural services and derive the monetary value of social landscape through valuing socio-cultural services of Negombo lagoon. A discrete choice experiment approach was used to estimate the individual’s preference towards social landscape by incorporating featured attributes. The individual preference was expressed through the marginal willingness to pay (MWTP) by integrating a monetary attribute into choice sets. Thus, the MWTP or the implicit price of social landscape attributes included in the choice task was estimated and then the total social landscape value was derived as 13,055 LKR per monthly per household. The social landscape values of Negombo lagoon demonstrated the important ecological, and socio-cultural knowledge, which should be integrated as guiding policies in ecosystem conservation and management strategies. Further, the challenging management paradigm for coastal and marine landscape of Negombo lagoon, and associated services should contain not only the biological and physical benefits but also socio- cultural values too.

Unravelling Lessonia trabeculata management in coastal areas of the Atacama region of northern Chile through a DPSIR approach: Insights for sustainable plans

Subtidal Lessonia trabeculata is one of the primary kelp resources of northern Chile. It is an ecosystem engineer that provides habitat, shelter, and food for invertebrates and fish. This fishery has been developed by a collection of stranded algae carried out by legally registered fishers and illegal collectors in open-access areas and management and exploitation areas for benthic resources. Due to the current high demand on the international market, the collection of dead plants is supplemented by direct extraction. In response, a management plan has been implemented to regulate extraction efforts and institute annual quotas. The dynamics of the L. trabeculata fishery in the Atacama region over 20years were evaluated using the conceptual framework of the driver-pressure-state-impact-response (DPSIR) approach. The fishing dynamics are strongly conditioned by price fluctuations, promoting the growth of fishing efforts (pressure) in response to economic indicators (driving forces). This often leads to a high volume of extractions of resources (impact) reflected in the increase in extractors and landings in spite of the establishment of quotas (responses), that generate intense pressure on local populations of algae and other commercially important fish and invertebrates (state). A lack of knowledge was detected regarding population aspects and its associated communities. Consequently, this kelp has been mismanaged without a specific focus on this species. Finally, the indicators included in the present DPSIR analysis enable a global understanding of the L. trabeculata fishery, and it should be considered as a basis for future studies and the implementation of resource management strategies.

Incorporating Fishermen’s Local Knowledge and Behavior into geographical information Systems (giS) for Designing marine Protected areas in Oceania

Drawing on our experience in establishing marine protected areas (MPAs) in the Roviana and Vonavona Lagoons, New Georgia, Solomon Islands, this paper shows how a geographical information system (GIS) database can be used to incorporate sociospatial information, such as indigenous knowledge and artisanal fishing data, along with biophysical and other information to assist in MPA design. We argue that converting peoples’ knowledge and socioecological behavior into geo-spatial data allows researchers to formulate hypotheses regarding human responses to inter- and intra-habitat variability, along with other marine ecological processes, and help in the designing and implementation of resource management strategies in a cost-effective and participatory way, bridging the gap between indigenous and Western cognitions of seascapes. More generally, we show the significance of combining spatial tools, anthropological fieldwork, and social and natural science methods for studying artisanal fisheries with the goal of aiding the design of marine protected areas.
