Abstract:

<p><strong>Abstract.</strong> Historical landscape and habitat reconstruction can be an important mitigation tool for regional habitat loss, conservation and restoration (NRC 1992; Swetnam et al. 1999; Steiner 2000). Among landscapes and habitats, wetlands play an important role in providing ecosystem services. Any loss of wetland areas may cause serious and sometimes irreparable environmental and habitat damages (Soule, 1991). Wetlands have a paramount importance for ecosystems and are protected by the Ramsar Convention and regulated and valorized, in different ways, by loca

Abstract:

This is a historical overview of the role that wetland science has played in regard to wetland management policy in North America. The major focus will be U.S. based since this is where wetland science has a direct link to policy and vice versa. From an international perspective – please see the book- Sustaining the World’s Wetlands: Setting Policy and Resolving Conflicts. The linkage of wetland science to policy has not always been symbiotic as one can see from this article, but even the problematic nexus issues are instructive.

Abstract:

The homogenization of freshwater ecosystems and their biological communities has emerged as a prevalent and concerning phenomenon because of the loss of ecosystem multifunctionality. The millions of prairie-pothole wetlands scattered across the Prairie Pothole Region (hereafter PPR) provide critical ecosystem functions at local, regional, and continental scales. However, an estimated loss of 50% of historical wetlands and the widespread conversion of grasslands to cropland make the PPR a heavily modified landscape. Therefore, it is essential to understand the current and potential future stres

Abstract:

Constructed wetlands (CWs) for wastewater treatment are engineered systems that are designed and operated in order to use all natural processes involved in the removal of pollutants from wastewaters. CWs are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The basic classification is based on the presence/absence of wastewater on the wetland surface. The subsurface flow of CWs can be classified according to the direction of the flow to horizontal and vertical. The combination of various types of CWs is call

Abstract:

A wetlandscape is a landscape characterized by the presence of numerous interconnected wetlands (Bertassello et al. 2018). Loktak located in the Manipur River basin in India is a unique wetlandscape that includes numerous floodplain wetlands and associated channels. It hosts the Loktak wetland, the largest freshwater body in the northeastern India, also designated as Ramsar site and the Keibul Lamjao National Park, the only floating national park in the world. Like any other wetlands in the world, Loktak wetlandscape is also under great threat due to the changes in the hydrometeorological cond

The U.S. Army Corps of Engineers, NY District’s wetland mitigation proposal for Finderne Farms in Bridgewater, NJ, was approved in August 2005 by the state regulatory agency. The design goal was to provide mitigation for wetlands impacted by the Green Brook Flood Control project at a ratio of 2 : 1. As part of the design process in 2001, the available historical hydrologic data was evaluated. At that time, the NJ Department of Environmental Protection (NJDEP) Water Budget Manual was not available as a tool for accessing an acceptable design hydroperiod.

Abstract:

Cyanobacteria and other microbes are important moderators of biogeochemical processes in semi-arid floodplain wetlands with varying inundation regimes. Inundation is a key environmental driver for floodplain biological communities. Little is known about the effect of historical inundation frequency on the spatial abundance of floodplain–wetland Cyanobacteria and other microbes. In this study, soil samples were collected at two locations with a gradient of low-to-high inundation frequency in the Macquarie Marshes, south-east Australia. We used high-throughput sequencing to estimate the proporti

Abstract:

The Everglades, the largest Ramsar wetland in the USA, is a spatially complex mosaic of freshwater habitats heavily impacted by agriculture, urban land use, and efforts to manage water resources in southern Florida. Restoration and conservation of these habitats is challenging because they experience different threats, and require different water levels, hydroperiods and disturbances. Historically, Everglades hydrology was maintained by seasonal precipitation and surface-water flows, but was significantly altered in the 20th century to foster agriculture and urban growth.

Abstract. Recently, the provision of food and water resources of two of the world's largest river basins, the Murray and the Yangtze, has been significantly altered through widespread landscape modification. Long-term sedimentary archives, dating back for some centuries from wetlands of these river basins, reveal that rapid, basin-wide development has reduced the resilience of biological communities, resulting in considerable decline in ecosystem services, including water quality. Large-scale human disturbance to river systems, due to river regulation during the mid-20th century, has transform

Abstract:

Wetlands, particularly those in semi-arid or arid environments, are hotspots of biological diversity and productivity. Water resource managers are therefore increasing their efforts to conserve wetlands from environmental degradation. To do this, they require a thorough understanding of the wetting and drying regimes of these wetlands, and how potential land use, climate change and water resource development might affect inundation patterns. Hydrologic models can help to enhance this understanding, and to predict and assess future impacts. However, for semi-arid environments, data to assist in

Abstract:

Continuous urban expansion worldwide has resulted in significant wetland degradation and loss. A limited number of studies have addressed the coupling of wetland and urban dynamics, but this relationship remains unclear. In this study, a time-varying methodology of predicting wetland distribution was developed to support decision-making. The novelty of the methodology is its ability to dynamically simulate wetland shrinkage together with urban expansion and reveal conflicts and potential tradeoffs under different scenarios. The developed methodology consists of three modules: a historical chan

Abstract. Natural methane emissions from wetlands and fire, and soil uptake of methane, simulated using the Canadian Land Surface Scheme and Canadian Terrestrial Ecosystem (CLASS-CTEM) modelling framework, over the historical 1850–2008 period, are assessed by using a one-box model of atmospheric methane burden. This one-box model also requires anthropogenic emissions and the methane sink in the atmosphere to simulate the historical evolution of global methane burden. For this purpose, global anthropogenic methane emissions for the period 1850–2008 were reconstructed based on the harmonized rep

Crop production needs to double to feed the world’s growing population. Indonesia, as the fourth most populated country in the world, needs to meet its food security challenge with a shrinking arable land area. Indonesia has over 34 million ha of swampland. The scarcity of arable land in Indonesia means wetlands are likely to be converted to agricultural use. The challenge is to both profitably and sustainably do so.
