Abstract (sommario):

Wetlands have a very important role for humans and the environment. The function of wetlands as a support for human life, among others, water sources, a variety of habitats for living things, controlling floods, and drought. One of the wetlands in the Kelik river, Ketapang Regency. This wetland has an area of 2600 ha. The land is now a conservation area, with cultivation rights. The existing problem, namely, the land is the residual combustion that occurred in 2015 and is always flooded with water and the need for an existing drainage system on the land. Land needs to be managed properly in water management. Efforts to manage conservation areas so as not to experience drought, which results in fires, which will threaten land conservations. Methods for dealing with drainage systems by utilizing existing ditches or drains. Drainage design using hydrological and hydraulic studies. The method used in determining the flood discharge plan is based on the need for drainage modulus and the area of the ArcGIS software aid sub-area. The results of the study indicate the need to improve the existing channel. Repair through efforts to deepen the trenches and hold widening or normalization. Also, the depth of the new channel is needed to make an automatic door so that the water can be grounded to maintain the availability of water in the ground.

Abstract (sommario):

Abstract Greater Painted-snipe (or Greater Painted Snipe) Rostratula benghalensis is medium-sized wader that inhibits the wetland habitats in Africa and south and southeast Asia. Despite of its English name, Greater Painted-snipe does not belong to the true Gallinago taxa. The female in this species is the colourful mate while the male brownish with pale spots in general and smaller in size. This species is of least concern (LC) conservations status on the IUCN Red List. During one of the field surveys carried out by the Iraq Organization for Conservation of Nature (IOCN) in Iraq, the team was able to find this species in a meadow wetland of low grass close to River Euphrates bank, northwest of Basra Governorate which represents the first observation of this species in Iraq. By providing the documented observation and detailed description of this species, this paper confirms the first record of Greater Painted-snipe (or Greater Painted Snipe) Rostratula benghalensis as an addition to the Iraqi birds checklist.

Abstract (sommario):

Abstract Utliukskiy Liman is one of three typical and at the same time unique limans in the northwestern part of the Azov Sea Region of Ukraine. Despite the considerable anthropogenic transformation of the liman it continues to be a valuable wetland for migratory waterbirds. The current publication based on data collected from 1994 to 2015, in the period of autumn migrations 19 counts were conducted at Utliukskiy Liman. In total 1,134,832 ind. of 90 waterbird species (8 orders) were recorded. Averagely at liman were presented 59,728 waterbirds, with maximum 115,095 individuals. Throughout the season, many characteristics of waterbirds at Utliukskiy Liman are varying significantly due to the timing of migration of different waterbird species and their abundance. Detail information on this is presented in the paper. Among the counted birds, 60 species have certain conservations status. Maximum number of 20 counted species exceeded 1% of their geographical populations. According to obtained results, Utlyukskiy Liman occupies a stable place among the five most valuable wetlands of the Azov-Black Sea coast of Ukraine — in different years from 5th to 1st place on the total number of waterbirds.

Abstract (sommario):

Wetland conservation has gradually improved worldwide. In situ conservation is effective in protecting valuable wetlands. Here, we review the expansion, reformation and problems associated with wetland conservation in China. The wetland conservation system in China comprises a wetland protected area network (nature reserves, wetland parks, urban wetland parks, aquatic germplasm reserves and special marine reserves) and a wetland grading system. Following rapid expansion, national wetland protected areas cover 4.78% of the country. At the same time, a wetland grading system that categorises the importance of wetlands has expanded to 13 provinces. However, reforming wetlands, including improving the role of wetlands, adjusting departmental responsibility, reforming conservation systems and implementing comprehensive wetland conservation regimes, is somewhat arduous and complicated at present. Although these changes have contributed to wetland conservation in China, the wetland conservation system still faces considerable problems because of a lack of uniform and efficient regulations. Management functions and spatial scope overlap in different systems, and there is a disconnect between resource management and law enforcement. A unified legal system and wetland identity cards should be established, with stronger law enforcement. Synergy between wetland conservation systems should improve, innovative wetland conservation mechanisms should be used and better coordination among different protection systems is needed.

Abstract (sommario):

This work compares the applicability of several free-surface evaporation and runoff equations in simulating water level variations of small Mediterranean wetlands. The Amarga and Jarales wetland are two pilot sites with an evaporite-karst genesis located in southern Spain. The water level was continuously recorded in both wetlands, and exhaustive weather monitoring was performed. The combined datasets have permitted quantification of the surficial elements of their water budget (precipitation, runoff, and evaporation). Several campaigns of groundwater level measurements were also done to characterize the direction of groundwater flows. The morphometrical analysis of the Jarales wetland was accurately performed based on a LiDAR dataset. A total of 225 limnimetric simulations of the Jarales (90) and Amarga (135) wetlands were performed, combining different evaporation and runoff equations. During the study period, the curve number method, coupled with the Penman equation, reached the Jarales wetland’s best calibrations. The Vardavas–Fountoulakis modification of the Penman model fit better with the Amarga wetland record. The obtained results permit specification of the water budget of both wetlands during several years and confirm that the groundwater–surface water relationship affects the wetland hydric dynamic to different degrees. Nonetheless, the limnimetric models were calibrated for a short period, including dry years, making it necessary to extend the control period longer and validate the models under different hydroclimatic conditions. Finally, the differences between wetland functioning are explained in a conceptual hydrological model that can be useful for wetland conservation and management of related aquatic ecosystems. The understanding of the origin and fate of water in wetlands permits assessment of how future scenarios would affect hydric functioning and suggests adequate conservation measurements.

Abstract (sommario):

As the wetlands has decreased and degenerated badly due to human’s excessive use, it becomes to be a hotspot in international academe’s forefield to resume and rebuild wetlands. Simply opposing protection to using can effectively ease up the stress of wetland’s degradation in a short term, but is disadvantageous to wetland’s sustainable development. This article takes Tianjin Qilihai wetland as example, aiming at its existing problems, sums up two kinds of infection genes – exterior representation and interior motivation, and intensively analyzes the sticking point from three aspects – economic, acknowledgement and mechanism. It suggests that basing on the idea of accretion and co-prosperity, we can divide wetland area into three zone – core zone, buffer zone and experimental zone, and then let the interior dispersive inhabitants and production activities move out to the intensively constructed eco-town. Thus we can make scientific use of wetland’s economical value and promote circumjacent industries’ transformation. Moreover, by the recycling use of water on a model of source separation combined with wetland classification, the quantity of regenerated water would reach 18.25 million cubic meters. By the Low Impact Development (LID) strategies in the control and use of rainfall and flood, the quantity of rainwater for use would reach 8.62 million cubic meters per year. In this way, the wetlands’ ecological conservation would obtain regurgitation-feeding, the construction of eco-town would be organically combined with protection and using of wetlands, and an effective system of wetlands’ sustainable development and using would be established.

Abstract (sommario):

Artificial wetlands are built to meet the rising human population's water needs, with little attention paid to their ecological significance. The current study was carried out to assess the importance of artificial wetlands in biodiversity conservation. Habitat quality of wetlands was assessed using the birds as an ecological indicator. Bird surveys were carried out at the five artificial wetlands located in the Ajara conservation reserve, northern Western Ghats, India. Bird surveys were conducted for five years (2011–2015). During the study, 165 bird species were recorded, including 34 wetland birds and 131 wetland-associated birds. Wetlands in forested areas have a higher richness of wetland birds. Wetlands surrounded by exotic plantations, agriculture, and human settlements exhibit lower wetland bird richness than wetlands in forested areas. Land use attributes around the wetlands affect wetland bird diversity. The current study gives a glimpse that these artificial wetlands could serve as a possible habitat for wetland birds.

Abstract (sommario):

SUMMARYLaws are crucial tools to protect wetlands. How these laws are written has important implications for conservation. We assessed all wetland terms and definitions in Brazilian legislation to identify whether legislation uses any generic terms to represent several or all types of wetlands and to determine if definitions with clear descriptors exist that can easily be used to identify wetland systems. A total of 116 local wetland-related terms and 21 wetland definitions were found in Brazilian legislation. A direct Portuguese translation of the term ‘wetlands’ was found only once in the New Forest Code. The insertion of the term ‘wetlands’ in the New Forest Code has important practical implications for the conservation, since all different Brazilian wetland types would be represented by the generic term ‘wetlands’. The existence of a definition of the term ‘wetlands’ associated with attributes of water and biota in Federal legislation will help environmental technicians to identify wetland systems and to recognize different wetland types. The insertion of this definition in the New Forest Code would make it clear that the drainage of any wetland type – large or small – is prohibited, and those who do so would be breaking Brazilian environmental law.

Abstract (sommario):

Wetlands are important ecosystems in southern Brazil because they show high productivity and biological diversity. However, conservative data indicate that ~90% of the wetlands have disappeared as a result of agricultural expansion. In this sense, the understanding of species composition and richness patterns in fragmented and natural wetlands is a priority for biodiversity conservation strategies. The main goal of the present study was to determine how much variation in macroinvertebrate richness and composition is explained by wetland area, hydroperiod and altitude. This survey was carried out in an extensive area of the Neotropical region (~280000 km2 – southern Brazil) with a large number of wetland systems (72) and covering a wide gradient of altitude and wetland surface area. The macroinvertebrate richness was higher in permanent wetlands than intermittent ones, and intermittent wetlands supported a macroinvertebrate composition that clearly differed from those of permanent wetlands. Macroinvertebrate richness was positively affected by wetland area; however, this relationship was significant only in permanent wetlands. There is a need to promote conservation of all wetland systems in southern Brazil, regardless of their hydroperiod and area. These arguments are essential to develop conservation and management programs of wetlands in this region.

Abstract (sommario):

The restoration of natural wetlands is a wonderful, noble and pragmatic idea, but such efforts often meet resistance from certain segments of society. One reason for this is that the public perceives the environment in different ways than do the experts, such as landscape architects and land managers. This dissertation analyzes peopleâ s preferences for wetlands in comparison to those of landscape architects. It specifically studies the conflict about the wetland restoration program in the Malaysiaâ s Kelana Jaya Municipal Park. This dissertation is based on data obtained from a preference survey using photo questionnaires that polled both the publicâ s and landscape architectsâ group preferences for wetlands. The data was analyzed using the Content Identifying Method (CIM) to determine group preferences for wetlands and factors that influence these preferences. Park managers from several local authorities also were interviewed to determine their expectations of public preferences and attitudes toward wetland restoration and public participation. The public and landscape architects have significantly differed in stated preferences for wetlands. The public strongly prefers park-like landscapes that demonstrate human influences and provide the potential for human involvement; in contrast, landscape architects prefer natural wetlands that are visually pleasing, with well-defined spaces, visual coherence, and visual complexity. In addition, park managers did not accurately predict the publicâ s view of wetlands. Their prediction was similar to landscape architectsâ preferences. Attitudes toward wetland activities and safety, knowledge about wetland benefits, the motivation to use urban natural open spaces, and familiarity with nature significantly affected the publicâ s preferences. Further, the motivation to use urban natural open spaces was the best predictor of publicâ s preferences. The primary implications of this dissertation are that environmental education should be a core activity in changing peopleâ s perceptions of natural wetlands and that opinions of local people should be incorporated in many aspect of wetlands restoration, planning, design, and policymaking, especially in Malaysia.

Abstract (sommario):

This thesis examines the relationship between the underlying ecological values of wetlands and the economic values they produce. The importance of the roles that wetlands play is now well recognised yet losses continue at a global level. It is argued that one cause of wetland loss is a lack of awareness of the values of these systems due to inadequate information of the nexus between ecological functions and economic values. For example, the off-site, indirect benefits provided by wetlands have largely been ignored. This has led to an undervaluation of these ecosystems. The integration of ecological and economic values requires incorporating differing types of information and systems of value derived from differing disciplines with differing paradigms. To understand the differing disciplinary perspectives the thesis explores the ecological functions of wetlands and the economic goods and services that they provide. The functions and benefits of wetlands are linked at the ecological-economic interface. A consensus on the definition of ecological value could not be discerned within the discipline of ecology. Thus, a definition and index of ecological value is developed to demonstrate the attributes of coastal and wetland systems that provide for instrumental human benefits. These attributes include productivity, the ability to provide habitats for dependent species and the diversity of species and organisation they support. However, ecological information is not presently available to operationalise the index. The ability of economic techniques to capture this ecological value is then investigated. Three approaches for assessing non-market values (direct linkage models, revealed preference and stated preference models) are reviewed with respect to their ability to capture ecological value. An alternative biophysical approach, namely energy analysis, is also considered. The review suggests that it may be possible to measure ecological value using the contingent valuation method. The role of information in preference formation and willingness to pay bids is then investigated along with a number of other issues that need to be resolved before using the contingent valuation method. The wetlands of the case study area, Moreton Bay, Australia exhibit both ecological and economic values. The wetlands contribute approximately one-third of primary productivity in the Bay, provide habitat for a wide range of dependent species (including internationally recognised migratory wader birds) and have a diverse fauna with a relatively large number of endemic species. Economic values of the wetlands include both direct and indirect use values (for example, fishing, recreation, water quality improvements and storm buffering) and non-use values. Non-use values include the value in preserving the environment for future generations (bequest value) and the existence of vulnerable animals such as turtles and dugongs, which one may never expect to see. If consumers are willing to pay to preserve these animals, this is also a valid economic value. The economic technique of contingent valuation is tested to determine if it is possible to capture ecological value by providing respondents, selected by random sample, to a survey with the relevant information. A case study is undertaken in Moreton Bay to determine respondents' willingness to pay to improve water quality and hence protect the wetlands. To test the effects of differing types information, four different versions of the survey were sent to four groups of 500 respondents. Case A provided no extra information so it could be used as a control. Case B included information about the ecological values of the wetlands of Moreton Bay. Case C provided information about the economic use values of the wetlands in the Bay including direct and indirect use. Case D provided information about the non-use values of endangered species resident in the Bay that are dependent on the wetlands. The results indicate that the provision of different types of information influences willingness to pay. However, willingness to pay when provided with ecological information is not significantly different from willingness to pay when provided with other information. As it was not possible from the research undertaken to state that the contingent valuation method can capture ecological value, an alternative approach is proposed to link ecological and economic values. It is argued that ecologists and economists need to develop common aims and scales of assessment. Further, communication between the two disciplines can be enhanced through the use of agreed indicator terms. Through an iterative approach it should then be possible to understand the linkages between changes in indicators of ecosystem values and indicators of economic value.

Abstract (sommario):

Globally, amphibians have suffered dramatic population declines in the past twenty years with habitat destruction implicated as the primary threat. The Natural Resources Conservation Service’s Wetlands Reserve Program (WRP) restores wetlands on marginal agricultural land and is a means to restore the spatio-temporal wetland habitat required by amphibians to prevent, reverse, or stabilize declining population trends. The goal of WRP is “to achieve the greatest wetland functions and values, along with optimum wildlife habitat, on every acre enrolled in the program.” Functions and values are defined as the hydrological and biological characteristics of wetlands. A key unanswered question is to what extent is this goal being achieved? Amphibians enable quantifying the WRP goal due to their life-history requirements and explicit incorporation of their habitat needs into WRP plans. My research goal was to determine if hydrological and biological wetland characteristics had been restored to WRP sites in the Lower Grand River basin, north-central Missouri, based on distribution, recruitment success, and relative species richness estimates for members of a regional species pool. I identified three design strategies applied to WRP sites over time: walk-away, maximize hydrology, and naturalistic; the latter emphasizing restoring process as well as structure; and evaluated if design strategy was a useful covariate for restoration efforts. I encountered 10 amphibian species representing 59% of the regional species pool. Design strategy was not a predictive site-level covariate as sites within all three design strategies had varying hydrological wetland conditions resulting in greater habitat heterogeneity than anticipated on maximize hydrology and walk-away sites and less than anticipated on naturalistic sites. Amphibian detections occurred across all sites resulting in no difference among design strategy as the degree of heterogeneity in habitat conditions at the within site-scale demonstrated that amphibians were responding to ecological conditions that occur at a finer resolution than site. Results, irrespective of design strategy, indicate seven of the detected species or groups were widely- distributed, two were moderately- distributed, and two were sparsely distributed on WRP sites indicating hydrological wetland characteristics have been restored to sites given the moderate- to wide-distribution of species associated with both seasonal and permanent wetlands. Although species were successfully recruiting young into adult populations, only leopard frogs had high estimates of recruitment success whereas the remaining species had moderately high to moderate to low recruitment estimates indicating biological wetland characteristics are somewhat lacking to lacking for these species. Results from the relative species richness assessment indicate that, whereas 74% of the sites provided some degree of wetland habitat for members of the regional species pool over the course of the field season (7 March – 19 September), 52% of the sites lacked suitable habitat conditions during the peak of amphibian breeding and larval development (May through July). Targeting management actions that result in suitable seasonal wetland habitat conditions (shallow, vegetated wetlands that gradually dry by mid-to late-summer) throughout the time needed for species to complete their life history requirements is one method to increase the biological wetland value of restored WRP sites. Results show the value of WRP at conserving and restoring river-floodplain amphibians; however, achieving optimum wildlife habitat on every enrolled acre will be difficult at a site-level scale as habitat requirements, although overlapping, vary widely for the full range of species. Providing for all species in the regional species pool requires sites that transverse both the longitudinal and lateral floodplain gradient. If WRP is to realize its full potential, there must be recognition that optimum wildlife habitat can be defined at multiple spatial and temporal scales that match the landscape setting. Optimum wildlife habitat at a wetland scale is not the same as optimum wildlife habitat at the floodplain scale. The intent of WRP is to convert marginal, flood-prone agricultural lands back into wetlands so enrollment of lands located outside the active floodplain may be impracticable or unrealistic. Whereas attaining optimum wildlife habitat on every acre enrolled in the program may not be an achievable objective, providing optimum wildlife habitat for members of a regional species pool within an appropriately defined geography that includes both a longitudinal and lateral gradient represents an objective that is both desirable and attainable.

Abstract (sommario):

AbstractThe future of wetland bird habitat and populations is intrinsically connected with the conservation of rangelands in North America. Many rangeland watersheds are source drainage for some of the highest functioning extant wetlands. The Central and Pacific Flyways have significant overlap with available rangelands in western North America. Within these flyways, the importance of rangeland management has become increasingly recognized by those involved in wetland bird conservation. Within the array of wetland bird species, seasonal habitat needs are highly variable. During the breeding period, nest survival is one of the most important drivers of population growth for many wetland bird species and rangelands often provide quality nesting cover. Throughout spring and fall, rangeland wetlands provide key forage resources that support energetic demands needed for migration. In some areas, stock ponds developed for livestock water provide migration stopover and wintering habitat, especially in times of water scarcity. In the Intermountain West, drought combined with water demands from agriculture and human population growth are likely headed to an ecological tipping point for wetland birds and their habitat in the region. In the Prairie Pothole Region, conversion of rangeland and draining of wetlands for increased crop production remains a significant conservation issue for wetland birds and other wildlife. In landscapes dominated by agricultural production, rangelands provide some of the highest value ecosystem services, including water quality and wetland function. Recent research has shown livestock grazing, if managed properly, is compatible and at times beneficial to wetland bird habitat needs. Either directly, or indirectly, wetland bird populations and their habitat needs are supported by healthy rangelands. In the future, rangeland and wetland bird managers will benefit from increased collaboration to aid in meeting ultimate conservation objectives.

Abstract (sommario):

According to the definition of the International Union for Conservation of Nature and Natural Resources (IUCN), wetlands on Earth are areas that are flooded or saturated with water, artificial or natural, permanently or temporarily flooded with standing, sitting or running water. These areas include areas where water is the predominant element, such as swamps, wetlands, peatlands, estuaries, sea branches and lagoons, lakes, rivers and artificial reservoirs with a depth of more than six meters. Considering the importance of these territories and with the deep conviction that the preservation of their flora and fauna can be ensured by combining long-term national policy with coordinated international action, the scientific community reacted to the encroachments and unreasonable attitude to them by concluding 02.02. 1971 of the Convention on wetlands of international importance, especially as waterfowl habitats, known to the general public as the Ramsar Convention. The main objectives of this document are to manage wetlands as sites of great economic, cultural, scientific and conservation value, to avoid damage and loss and to preserve them through prudent use, i.e. through their continuous development. The object of study in the present work is the biological diversity, in particular the avifauna of some of the internationally important wetlands in the border areas between Bulgaria, Greece, the Republic of North Macedonia and Albania in view of the opportunities they offer for the development of some forms of alternative types of tourism.

Testo completo

Abstract (sommario):

The wetlands of the lower Songkhram River basin are protected as a Ramsar site and a regional environmental asset, but they are under threat from numerous factors related to developmental activities. The lower Songkhram River is the last free-flowing tributary of the Mekong River and is a lifeline for over 14 000 households and a haven to many endemic biodiversity species. Local communities in the region have unique associations with the natural resources in the river basin, including the wetlands, and they perceive immense value in conserving these ecosystems. Natural resource policies lack specific guidelines and collaborative approaches for the protection, conservation and management of the wetland resources of the lower Songkhram River. The way forward should be led by a synchronized planning process, collaborative governance of the wetland resources, and empowerment of already existing local community groups.

Abstract (sommario):

Wetland conservation and restoration is an essential component of delivering the Kunming-Montreal Global Biodiversity Framework (KM-GBF) vision of a world living in harmony with nature where “by 2050, biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering benefits essential for all people.” This document supports the inclusion of ambitious wetland commitments and actions in National Biodiversity Strategies and Action Plans (NBSAPs) as a pivotal way of boosting biodiversity, to achieve the goals of both the Convention on Wetlands and the KM-GBF. This report focuses on the critical role of wetlands in achieving the 23 targets of the KM-GBF by 2030. It provides guidance to Parties to the CBD on how to incorporate the role and importance of wetlands and key actions into their NBSAPs in relation to each target. It also provides Contracting Parties to the Convention on Wetlands, with information on how to support delivery of the KM-GBF and achieve targets within the Fourth Strategic Plan of the Convention on Wetlands and the forthcoming Fifth Strategic Plan.

Abstract (sommario):

In a collaborative effort to advance climate adaptation resources available to wetland practitioners, the Wisconsin Initiative on Climate Change Impacts (WICCI) and the Northern Institute of Applied Climate Science (NIACS) have partnered to create adaptation resources for non-forested wetland management. This effort is also supported by the USDA Northern Forests Climate Hub. This publication provides perspectives, information, resources, and tools to wetland managers and natural resource professionals in the Midwest and Northeast regions of the United States as they endeavor to adapt natural communities and ecosystems to the anticipated effects of climate change. In this publication, we identify potential strategies and approaches that facilitate climate adaptation while meeting wetland conservation or restoration management goals and objectives. Adaptation strategies and approaches are intended to build upon current management actions that work to sustain ecosystems over the long term and support site goals while also adjusting systems to changing conditions. While it is beyond the scope of this publication to comprehensively address all potential adaptation tactics applicable to the conservation of wetlands, we provide examples to guide thinking, recognizing that individual wetland management projects have unique goals. Wetland professionals, reliant on their expertise and judgement, can use the adaptation strategies and approaches presented in this document to develop custom adaptation tactics based on the local conditions

Abstract (sommario):

US Army Corps of Engineers (USACE) reservoir projects significantly alter river ecosystem structure and function. Each project adheres to a defined set of operating rules to achieve primary objectives, which typically include flood risk management, hydropower, or navigation along with ancillary objectives for drinking water/irrigation, recreation, and natural resources management. Environmental flows (E-Flows) planning under the Sustainable Rivers Program has demonstrated new opportunities for environmental pool management (EPM; Theiling et al. 2021a, 2021b) that have no negative impact on other reservoir functions. In some locations, water level drivers can be managed to improve ecological outcomes, like wetlands, waterbirds, reptiles, and water quality, by altering the magnitude, timing, frequency, and duration of pool level changes that affect riparian and shoreline plant communities. Reservoirs with large delta areas may provide particularly important wetland or riparian habitat management along avian migratory pathways or in wildlife conservation regions (Johnson 2002). These large deltas can be identified and characterized using available satellite imagery, which along with water level habitat drivers available in hydrology databases, can be used to identify USACE reservoirs with good potential for EPM. A spatial analysis of USACE reservoirs capable to support EPM can be developed utilizing estimates of water occurrence, transition, and seasonality as well as surface elevation data derived from satellite imagery to assess geomorphology drivers. USACE water management records can be used to assess wetland drivers. Nationwide screening will be broken down into ecoregions to establish the anticipated geographic range of variation for wetland and riparian habitat drivers. Southwestern US reservoirs, for example, will have much different hydrology and fauna than Midwest and Eastern US reservoirs.

Abstract (sommario):

Conservation of freshwater biodiversity has been seriously neglected throughout the world, and entire ecosystems are threatened with extinction. Unfortunately, freshwater sustainability issues do not appear to be a primary consideration in the planning and implementation of water use projects, nor in the allocation of use permits. This paper discusses the value and function of Latin American freshwater ecosystems and gives a comprehensive approach to developing a sustainable water resources management policy. Case studies of the network of private nature reserves in Colombia, restoring the Mississippi River wetlands, and the Paraguay-Paraná Waterway project are presented.
