In urban wetland ecological system plants are important components, and plant landscape is one of the themes of landscape in the urban wetland and it is even the basic support of wetland ecosystem. The paper takes China Yangzhou Sanwan Wetland Park as a case, starting from maintaining wetland system ecological balance to protecting wetland functions and biodiversity, and realizing the sustainable use of the resources. Based on excavating the culture resources in Yangzhou, it also comprehensively utilizes natural wetland resources, surrounding natural and humanity resources to make a cultural and green plants group. So that we can build an urban wetland ecological system with “rhyme” and “green field”.

In order to clarify the natural purification potential of a natural wetland having free-flowing water, we performed a four-year study on such a wetland system which had been receiving for 12 years the domestic wastewater discharged from a residential area comprised of 45 households. The wetland's removal rate of organic matter throughout the four years ranged from 80% for COD to 95% for BOD, whereas the corresponding nitrogen removal rate was comparatively lower. Results indicate that NH4-N release from the bottom sediment and repression of nitrification are the main factors responsible for the wetland's low removal rate of nitrogen during winter. The wetland purification performance even in winter was determined as follows (g m−2 d−1): 2.2 BOD, 0.81 COD, 1.1 TOC, 0.10 T-N, and 0.023 T-P.

Wetlands provide important ecosystem services to rural communities. However, wetlands are often on communal land, so they may become degraded when individual users act to maximize their personal benefit from ecosystem services without bearing the full environmental costs of their actions. Although it is possible to manage communal resources sustainably, this depends on the dynamics of the socio-ecological system. In this study, we used a structured questionnaire to examine whether demographic characteristics of a rural community and the propensity for partaking in damage-causing activities affected the benefits obtained from the wetlands. Responses from 50 households in the rural Hlabathi administrative area within the Maputo-Albany-Pondoland Biodiversity Hotspot, South Africa, indicated that the entire community obtains some benefits from wetlands; most notably regulating ecosystem services. However, males were more likely to benefit from wetlands, which highlights a potential power imbalance. Respondents were more likely to blame others for wetland degradation, although there was no link between the damage-causing activities and benefits from wetlands. The high dependence on ecosystem services by community members, when combined with gender-based power imbalances and the propensity to blame others, could jeopardize the sustainable use of communal wetlands. Therefore, we describe how strong leadership could nurture a sustainable social–ecological system by integrating ecological information and social empowerment into a multi-level governance system.

This study used a bibliometric approach to quantitatively evaluate the status of wetland research in China using detailed information from 31794 articles retrieved from the Science Citation Index Expanded (SCIE) database and published from 1999 to 2019. We outline the progress of wetland research in China in terms of the number of articles published, active research institutions, funding provided, research directions, dynamic changes in the focus of the research and development trends. By analysing high-frequency keywords, we conclude that there are four focus areas of wetlands research in China: (1) climate change; (2) wetland pollution; (3) wetland plants and microorganisms; and (4) the conservation and management of wetlands. By combining focus area and high-citation analysis, we show that carbon storage and organic carbon mineralisation, biological remediation, constructed wetlands for the treatment of waste water and the sustainable use of ecological services are currently the most notable research areas, with a marked increase since 2009. These topics are in line with the focus of research globally over the past 6 years and are likely to become a primary research focus in future. The results of this study provide a useful theoretical basis and directions for further research in the sustainable development of wetland resources in China.

Natural water treatment systems such as wetlands are increasingly being recognised for their role as part of a multi-barrier system for water recycling. Natural wetland systems have the ability to provide effective treatment for a wide range of organic chemicals. However, techniques are required to validate the performance of these treatment processes in the field. This paper provides a new method for evaluating wetland systems using passive samplers and applies a statistical method for use in advanced water treatment processes. Three years of stormwater quality passive sampler data for diuron, simazine and atrazine is provided to determine herbicide removal between the inlet and outlet regions of a constructed wetland. Mean removal rates over the three year period for diuron, simazine and atrazine were 43, 54 and 50% respectively. The results show that this method coupled with passive samplers is amenable to wetland system barrier characterisation where opportunities for process validation is not feasible.

In Madagascar, as practically throughout the world, many protected areas were originally created with little consideration for the resource requirements of local people and consequently are now suffering from acute pressure from local exploitation. In an attempt to redress the problems, integrated conservation and development projects have been initiated. The original aims to protect a representative ecocomplex are now expected to be achieved by understanding people's requirements and enhancing traditional practices or providing alternatives, and the aims have been expanded to promote the sustainable use of resources also outside of reserves.These two projects, at Andohahela and Soalala, are duly considered, using a framework that has been developed to understand local people's behaviour in relation to resources. Economic, energy, cultural, and ecological, factors, acting as interdependent systems, are considered. The economic, energy, and cultural, factors influence each other, acting together to define the values or resources to people and driving their behaviour in relation to those resources. The behaviour affects the ecological system and may alter the availability of useful resources, depending on the level of use and their resilience. The availability of resources affects the energetic effort required to collect them, so establishing a feedback link.The aims of the projects are to establish ecological equilibria that protect the reserves and enable sustainable use to be made of resources outside the reserve. To achieve these goals they must influence people's behaviour suitably. Strategies include strengthening feedback from the ecological system, and providing energy or economic incentives. Development activities which aim to promote sustainable use of resources and protect biodiversity, through maintenance of the protected area, are assessed. Many projects give a high priority to income generation and improved access to social services; however, the conservation aims of a project often require a better targeted, resource management-based development package. This paper advocates the consideration of economic, energy, ecological, and above all cultural, factors in the design of effective activities for conservation and development projects.

Tropical wetlands are among the most productive ecosystems on earth which provide vital services and consist of various types of plant and animal communities that live in the water and on land. However, this golden area is one of the most undervalued ecosystems and the awareness on protecting the areas is still lacking among communities. The aim of this study was to review the wetland services in a tropical climate which functions to complete the ecosystem. In particular, this study will i) explore the values of wetland ecosystem towards human well-being in tropical culture and ii) to design a complete wetland ecosystem with respect to the local knowledge in a tropical climate. This study indicates that the new millennium of ecosystem services provided by tropical wetland has been disaggregated into provisioning of goods; regulating services, cultural development and supporting the process by considering the influence of Malay traditional wetland. Therefore, a complete tropical ecosystem is designed by imitating the natural wetland for societal well-being.

AbstractWetlands are abundant across the African continent and provide a range of ecosystem services on different scales but are threatened by overuse and degradation. It is essential that national governments enable and ensure the sustainable use of wetland resources to maintain these services in the long run. As informed management decisions require reliable, up-to-date, and large coverage spatial data, we propose a modular Earth observation-based framework for the geo-localisation and characterization of wetlands in East Africa. In this study, we identify four major challenges in spatial data supported wetland management and present a framework to address them. We then apply the framework comprising Wetland Delineation, Surface Water Occurrence, Land Use/Land Cover classification and Wetland Use Intensity for the whole of Rwanda and evaluate the ability of these layers to meet the identified challenges. The layers’ spatial and temporal characteristics make them combinable and the information content, of each layer alone as well as in combination, renders them useful for different wetland management contexts.
