Abstrak.Berbagai perubahan pada ekosistem sungai di perkotaan khususnya Sungai Code penggal Gemawang-Sardjito, mengindikasikan pemahaman masyarakat mengenai jasa ekosistem masih minim. Guna mengetahui kondisi sebenarnya, maka studi ini dilakukan. Tujuan yang ingin dicapai antara lain untuk mengetahui gambaran karakteristik ekosistem dan mengidentifikasi tingkat pengetahuan masyarakat mengenai jasa ekosistem dan komponen sungai. Penelitian menggunakan metode wawancara terstruktur dan observasi lapangan. Analisis deskriptif yang dilengkapi uji statistik dan analisis spasial digunakan dalam penelitian ini. Hasilnya menunjukkan bahwa dominasi talud dan permukiman menyebabkan menurunnya peranan ekosistem sungai. Pengetahuan masyarakat terkait komponen sungai minim, namun pengetahuan tentang jasa ekosistem cenderung tinggi. Sebagian besar masyarakat tidak bisa menentukan area sempadan sungai dengan benar. Selain itu, pengetahuan masyarakat terkait jasa ekosistem belum menyeluruh. Hal ini menunjukkan perlunya peningkatan pemahaman sosial masyarakat terkait ekosistem sungai. Abstract.Some changes in urban ecosystem of Code River, particularly in line Gemawang-Sardjito indicated the lack of community understanding to ecosystem services. This study was conducted in order to assess the actual conditions. The objectives of this study are to analyze the ecosystem characteristics and to identify the level of community knowledge regarding to ecosystem services and river components. This study used structured interview and filed observation. Descriptive and spatial analyses combined with statistical test are used in this study. The results showed that settlements and embankment caused the declining of river ecosystem roles. We also found that the community knowledge was high related to ecosystem services, however their knowledge to the river components was minimal. Most of them could not determine the riparian area correctly. Moreover, the community knowledge regarding to ecosystem services had not been thorough yet. Therefore, the improvement of community understanding to the river ecosystem is necessary.

Fisheries are an important resource in Zambia, but are experiencing overexploitation and are under increasing pressure from external development activities that are compromising river ecosystem services and functioning. One such system is the Kafue Flats floodplain, which is under threat from hydropower development. This paper reviews the effect of potential hydropower development on the Kafue Flats floodplain and explores mechanisms to optimise the expansion of hydropower while maintaining the ecosystem functioning and services that the floodplain delivers. Since completion of the Kafue Gorge and Itezhi-tezhi dams, seasonal fluctuations in the height and extent of flooding have been suppressed. This situation is likely to get worse with the proposed incorporation of a hydropower scheme into Itezhi-tezhi dam, which will operate under a hydropeaking regime. This will have major ramifications for the fish communities and ecosystem functioning and is likely to result in the demise of the fishery, along with destruction of the wetlands and associated wildlife. To redress the problem, it is recommended that an environmental-flow study is conducted, as initiated by World Wildlife Fund, to protect provision of the existing ecosystem services and optimise hydropower development, thus ensuring sustainability of the aquatic resources of the Kafue Flats for future generations.

Global Carbon

River ecosystems are one of the dynamic components of the terrestrial carbon cycle that provide a crucial function in ecosystem processes and high value to ecosystem services. A large amount of carbon is transported from terrestrial to the ocean through river flows. In order to evaluate the contribution of Sile River ecosystem to the global carbon stock, the river ecosystem Organic Carbon (OC) stock was quantified for sediments and dominant submerged aquatic macrophytes (SAMs) during the two sampling periods at three different stations along the Sile River (North Eastern Italy). The total mean ecosystem OC stock was 95.2 ± 13.8 Mg C ha−1 while those of SAMs ranged from 7.0 to 10.9 Mg C ha−1 which accounted for approx. 10% of the total OC stock. The total aboveground biomass retains approx. 90% of the SAM carbon stock, with a mean of 8.9 ± 1.6 Mg C ha−1. The mean sediment OC stock was 86.6 ± 14.5 Mg C ha−1 with low seasonal variations among the sites. Indeed, various environmental parameters and hydrodynamics appear to affect the accumulation of OC within the river ecosystem. The results highlight the role that freshwater river ecosystems play in the global carbon cycle, which consequently provide a baseline for future river ecosystem monitoring programs. Furthermore, future studies with additional sites and seasonal surveys of the river will enhance our understanding of the effects of global climate change on the river ecosystem and improve the ecosystem services.
