The valuation of Wetland Conservation in an urban/peri urban watershed
Regional Environmental Change, 2013Co-Authors: V. Lantz, Peter C. Boxall, Mike Kennedy, Jeff WilsonAbstract:This study estimates the social benefits of Wetland Conservation in the Credit River watershed, located in an urban/peri urban area in Southern Ontario, Canada. A stated preference approach was employed to value Wetland Conservation programs which ranged from retaining the existing Wetlands to restoring various levels of acres of Wetlands over the 2009–2020 period. A total of 1,407 households completed an internet-based survey which presented trade-offs in binary choice scenarios framed as referenda. Responses were analyzed using various models, one of which was a latent class analysis which segmented respondents into three classes. This econometric approach uncovered significant preference heterogeneity for Wetland Conservation. Assignment of respondents to the classes suggested that about one-third of the sample was willing to pay small amounts to retain the existing Wetlands. An additional third was willing to pay several hundred dollars a year for retention and small positive amounts for additional restoration. The final third were apparently willing to pay considerable sums for retention, but lesser amounts for additional restoration. However, further analysis revealed that respondents in this third class largely constituted yea-sayers. These results suggest caution in interpreting associated economic valuation estimates and highlight the importance of attempting to understand hypothetical bias in Wetland and other such valuation studies.

what did china s national Wetland Conservation program achieve observations of changes in land cover and ecosystem services in the sanjiang plain
Journal of Environmental Management, 2020Co-Authors: Hengxing Xiang, Zongming Wang, J. Zhang, Dehua Mao, Bai ZhangAbstract:Abstract China implemented the National Wetland Conservation Program (NWCP) from 2002 to protect and rehabilitate Wetlands. Under the background of sustainable development, assessment on the effectiveness of the NWCP is important to ecosystem management, especially in the Sanjiang Plain, the largest marsh distribution area and hotspot area with Wetland loss. To achieve this aim, this study examined the changes in land cover and ecosystem services (ESs) from 1990 to 2000 and from 2000 to 2015 in the Sanjiang Plain as well as the nine national nature reserves for Wetlands (NNRWs) by means of Landsat series images and the InVEST model. Results reveal that the NWCP played critical roles in reducing Wetland loss and improving regional ESs. The shrinkage rate of Wetlands in the Sanjiang Plain has been decreased remarkably, with a declined rate of Wetland loss from 750 km2 yr−1 to 189 km2 yr−1. The reduction rate of habitat area in good suitable grade and ecosystem carbon stock declined notably during the period 2000–2015 compared to the period 1990–2000. The amount of water retention increased by 5.4%, while the grain production capacity was enhanced by nine times from 1990 to 2015. Specifically, since 2000, the reduction rate of Wetland area in NNRWs (33 km2 yr−1) was obviously lower than that in the entire Sanjiang Plain, whilst various ESs in NNRWs were better than that in the whole Sanjiang Plain. This study is expected to provide an example for evaluating the effectiveness of the NWCP at other regions and support regional Wetland Conservation management.

The Legal Structure of Taiwan’s Wetland Conservation Act
Sustainability, 2014Co-Authors: Marc A. RosenAbstract:In July of 2013, Taiwan passed its Wetland Conservation Act and will begin the implementation of the Act on 2 February 2015. With this Act, Taiwan has become the second Asian country to have specific legislation on Wetland Conservation and protection. This new law enables the society to achieve sustainable utilization on Wetland ecological services. The core concepts of the Wetland Conversation Act include biological diversity Conservation and wise use of Wetland resources. Special political circumstances prevent Taiwan from registering its Wetlands as a Conservation priority under the Ramsar Convention. This new law allows the government to evaluate and assign a specific area as a "Wetland of Importance." Under this status, any development activities within the designated area shall be prohibited unless the developer prepares a usage plan for review. The usage plan and the original usage of the natural resources within the Wetland area shall also follow the "wise use" principle to protect the Wetland and biological service system. However, this new law does not provide clear separation between the two different "wise use" standards. If the development is deemed necessary, new law provides compensation mitigation measures to extend the surface of the Wetland and provides additional habitats for various species. Wetland Conservation and management rely heavily on systematic research and fundamental data regarding Taiwan's Wetlands. Determining how to adopt these scientific methodologies and transfer them into enforceable mechanisms is a sizeable challenge for both biologists and lawyers as the Wetland Conservation Act creates many legal norms without clarifying definitions. This article will review the current Wetland regulations from the legal perspective and provide suggestions for enforcement in the future.
