The present study provides scenario of wetlands of Sirohi district of Rajasthan, India. Landsat TM data of October, 1992, IRS-P6 LISS-III data of October 2005 and IRS-P6 AWiFS data of January, February, March, April and May months (2005) have been used in the study. Visual interpretation technique was adopted to map the areal extent of wetlands on 1:50,000 scale. Wetlands were classified following the Ramsar classification. The total extent of wetlands for the Sirohi district as a whole is estimated to 11,961 ha with representation 189 wetlands during 1992 which later decreased 11,307 ha in 2005 with a loss of 654.2 ha during 13 years. Of the total wetland area of the district, rivers accounted for 61.9% area, followed by reservoirs (15.1%), seasonal lakes (15%), perennial lakes (5.6%), and ponds (2.5%). Further it is also observed that drastic reduction in the water spread area from February to May months. For conservation of wetlands it is necessary to assess the changes which take place in the water bodies from time to time.

These wetlands which have historically provided a range of water services to the city are now believed to be threatened by degradation due to the recent changes in the urbanization patterns and urban lifestyle in Colombo. This paper presents a study on the current state and recent trends in surface water quality in a selected segment of these wetlands. The study was carried out as a part of a broader multidisciplinary research. The paper consists of a historical analysis of trends in surface water quality parameters and situation analysis of short term spatial and temporal water quality variation in the study area. The research identified that water quality parameters indicating domestic wastewater related pollution showed an increasing trend during the study period. BOD, Phosphates and Fecal Coliform were recorded in levels exceeding the accepted ambient water quality standards. Concentrations of several heavy metals were also above the ambient water quality standards. A distinct difference was observed in water quality between peripheral areas and internal water ways of the wetland. All evidence directs towards severe water quality degradation in the wetland dominated by domestic waste discharges and scattered solid waste dumps. This condition may lead to a nutrient enrichment of the wetland and cause biological and physical responses that may affect adversely on the water services provided.

Hence, an inventory of wetlands of any region is a pre-requisite for their conservation and management. This study has been carried out to delineate the change in freshwater lake of ‘Deepor Beel’ wetland of Assam, India, using LANDSAT TM data. Field observation shows that the ecosystem is facing both natural as well as anthropogenic threats. Rapid urbanization, Illegal settlements, industries, invasive species ( Eichhornia crassipes ) are the major cause of this wetland decline. It has been found that massive decline occurred between the period 1991 to 2001 i.e., 1.891 sq.km which was at the rate of -0.171 per year where as the decline between the period 2001 to 2010 was found to be 1.013 sq. km which was at a rate of -0.101. The total area of open water bodies has decreased by 2.904 sq. km from 1991 to 2010 i.e. 59.19%. Thus the overall rate of change in the water bodies from 1991 to 2010 to other land use categories was found to be -0.145. Hence the study reveals the potentiality of Landsat TM data mapping the change in the wetland ecosystem. It is further hoped that the study will have high utility in preparing management plan for conservation of this ecosystem.

This paper focused the importance of diversified livelihood options for the resources users to increase income, diversify income sources and improve the wetland productivity. A long-term support to 2,004 resources users was provided to explore income generation schemes through skills and credit. Income generation activities were adopted in 15 different types of trades that covered poultry and livestock rearing, fish culture, operating small business, tailoring or establishing tree nursery. These offered greater income and stability for the resources users. The overall income gained by the resources users around 64% where income generation activities contributed 50% of the total income they gained in 2006. Fishing effort was reduced almost 43% and over 14% fishers left fishing. New livelihoods helped them moving into other occupations reducing dependency on wetland resources that enabled habitat and fish stock recovery. Exploring diversified livelihoods could help the resources users to involve in wetland resources restoration process without livelihood deprivation.

Wetlands in Yankari Game Reserve, Nigeria are key stone ecosystem that provides a stopover, breeding and/or foraging platform for migratory and resident birds. This study determined the density and diversity of birds in the wetlands of Yankari Game Reserve. Ten wetlands within the reserve were identified and surveyed. The sizes (kilometer square) and isolation distances (kilometer) of the wetlands were measured (using GPS and Map Source) to determine their effects on bird density and diversity. Point count survey method was used to count birds. One hundred and twenty three species of birds belonging to 51 families were recorded in the wetlands. Significant patterns in the densities of birds were observed across the wetlands (Kruskal-Wallis H, X2=167.116, P=0.001) and also sizes of wetlands (Wilcoxon test: Z= -2.803, P=0.005). There was differences in mean number of birds in survey time (Kruskal-Wallis, X2=15.784, P=0.045). Evenings were probably most preferred in bird-wetland utilization.

Various avifauna species were seen including those that are common and non- migrating. The predominant species are the little egret, Egretta garzetta and the maritime kingfishers, Todiramphus chloris whose sizes are remarkably bigger compared to its inland counterparts. This maybe attributed to the rich source of riverine food primarily crustaceans and fishes. Outwards towards the sea, in mangrove studded islet, a small population of the huge Egretta alba could be found roosting. The mangrove bounded-river starts in a snake- like contour until it widens into a vast area surrounding islets of varying sizes in its midst. A tourist can devote his time leisurely kayaking in a banca or taking a ride in a motorized boat to explore the aesthetic beauty of this river all throughout its length. The small but very few family to single nipa huts can be seen in its banks as well as modified shelters of fishermen on floating rafts.

Periphyton from rice stems, especially, from cultivars locally known as ‘ Amo ’ were collected from a depth of 7.0-8.0 cm from surface water and 5.0 cm above from the field bottom. Glass slides (15 × 18cm) were fitted in periphyton sampler and fixed at different depths. The rice fish environment was found to harbor rich periphytic diversity throughout the whole cropping season of 2002 and 2003. Total 88 genera of periphytic microalgae were reported from the environment with an order of preference of Chlorophyceae>Bacillariophyceae>Cyanophyceae. The Shannon Wienner diversity (H´) and evenness (J) indices of periphyton from rice stems indicated tendencies of Chlorophycea and Cyanophyceae to exhibit periphytic life on rice stems, whereas Bacillariophyceae preferred glass slide. Dry matter (DM) and Ash free dry matter (AFDM) values reflected the affinity of non algal periphytic resource to associate on both rice stems and glass slide. The results of periphytic Chl-a from rice stem was significantly higher to glass slides and show selectivity of algal periphytic resource to colonize on rice stem. Its sudden decline during late aquatic phase on rice stem explains heterotrophic nature of rice fish environment. The rice stems as natural substrate, thus, exhibited a rich ground for periphyton growth in rice fields of Apatani Plateau. It also stands as potential candidate to be used as a source for organic nutrients in the form of periphyton for aquaculture.

The zooplankton abundance showed distinct seasonal or temporal variation in the Jheels. A total of 18 species belonging to 12 families and 15 genera were recorded. The population density of total zooplankton showed summer maxima in the Jheel. Maximum abundance of rotifer fauna was recorded during summer season in sewage sites whereas Cladocera population showed maximum density at non-sewage sites. Copepods showed postmonsoon maxima in sewage sites in the Jheels. Some species i.e., Polyarthara vulgaris were quite abundant in the polluted water of the Santragachi Jheel. Out of 15 genera of Zooplankton, Brachionus, Keratella, Polyarthra, Diaphanosoma, Ceriodaphnia, Bosmina, Heliodiaptomus and Mesocyclops were found to be dominant in Santragachi Jheel. Highest percentage of similarity was recorded between S1 and S3 sites of the Jheel. Results of ANOVA (2 - way) indicated that zooplankton population differs significantly in relation to stations and seasons of the Jheel. Population of Rotifera, the most dominant group was found to be positively influenced by Biological Oxygen demand (BOD), Free Carbon-di-oxide FCO 2 ), CaCO 3 hardness (CaHa), Total suspended solid (TSS), Chloride(Cl) and Phosphate (PO 4 ) in the Jheels. Total Cladocera showed positive correlation with PO 4 in the Jheel. The Copepods expressed positive correlation with BOD and ammonia. Increment of population density of several zooplankton organisms (i.e., Keratella tropica , Polyarthra vulgaris ) and low value of community indices especially species diversity and species richness indicated the rise of pollutional stress on the Santragachi Jheel.
