Abstract: The wetlands of Kashmir are highly productive life support systems and are of immense socio-economical value to the people. The present studies concern with wetlands viz. Khushalsar, Anchar, Ahansar, Waskursar, Mansbal and Wular lake, which fall on the flood plains of River Jhelum and enjoy typical rural environment. The littoral zones of all these wetlands are occupied by emergent aquatic plants like Typha angustata and Phragmites communis, followed by rooted floating leafy aquatic plants like Nelumbo nucifera, Nymphaea alba, Nymphoides peltata, and Trapa natans which are extensively used for fodder, food and medicinal purpose. In the present study survey of such valued aquatic plants, their density, frequency, phenology, dry weight and therapeutic values were recorded in order to assess their role in maintaining the health of their users. The distribution frequency and density of various aquatic plants varied from wetland to wetland which could be because of availability of nutrients and the nature of the bottom sediment. It has been observed that the local knowledge on such valued plants abounds and their use is an important link between the dwelling communities and the biodiversity of the area.

Abstract: Important freature of any environmental strategy is that environmental objective require action in several areas, which typically lie in the purview of different ministries. The Ministry of Environment and Forests (MoEF) has the important role of monitoring the development process and its environmental impact in a perspective of sustainable development and to devise suitable regulatory structures to achieve the desired results. While this role is crucial, environmental objectives can be achieved if environmental concerns are internalized in policy making in a large number of sectors. This would require sharing of responsibility at all levels of government and across sectors with respect to monitoring of pollution, enforcement of regulations and development of programmes for mitigation and abatement. The Eleventh Five Year Plan of India has taken the due note of the concern in terms of threat to food security due to degradation of land, forest and overexploitation of groundwater, lack of access of the community to basic services particularly eneryg, drinking water, sanitation facilities, low level of socio-economic development, high incident of unemployment, stagnant infant mortality and under-nourishment amongst children and the deterioration in quality of life. There is a pathoply of evidence evidence to indicate that poverty reduction and sustainable economic growth is undetermined by degradation of soil, scarcity of freshwater, over-exploitation of coastal ecosystems, loss of forest cover, biodiversity as genetic, species and ecosystem level, and long term change in the climate. The Eleventh Plan therefore, marks a paradigm shift as it visualize that economic growth alone is not the objective of national planning and the development objective not to be GDP of per capita income, and to promote greater participation of the community in the decision making process. The eleventh plan has indicated the monitorable targets as indicators of human development as well as the human welfare as the determinant factor of the development strategy. The study of provisions regarding protection of the environment in XIth Five Year Plan reveals that definitely some attempts will be made in Indian economy to protect the enviornment. But it seems those are not adequate. Some additional provisions and efforts are necessary. This plan does not much talk on the problem of air pollution and noise pollution, which are very much important in urban areas and have very bad consequences. The plan also does not consider what can be role of the private, cooperative sectors and NGOs in the protection of the environment. Likewise, what responsibility a city in our country is expected to discharge concerning environment protection. The plan also lacks in providing for the problems of climate change and global warming.

Abstract: Soil is the source for most of the essential nutrients required by crops for their healthy growth. These nutrients are not always enough in the soil for a plant to grow healthy. The soil analysis provides the farmer with an estimate of the amount of fertilizer nutrients needed to supplement those in soils. Soil is studied for its pH, texture, percent exchangeable sodium, percent organic matter, and salinity expressed as electrical conductivity, water holding capacity and the nutrients available to plants. The present study deals with analysis of 23 soil samples belonging to three different ecological regions.

Abstract: An earthworm bioassay was conducted to assess the ecotoxicity of Annona squamosa oil cake amended soil using the species Eudrilus eugeniae. Mortality and abnormal morphology of earthworms exposed to different concentrations of the oil cake, i.e., 10, 100, 112.5, 125 amd 150 g/kg were examined. Mortality was measured as the ecological end point in the tests. Annona squamosa oil cake was toxic to the earthworm and the severity of the response increased with increasing concentration of the oil cake. The LC50 value showed that the mortality observed was significantly different from the negatice control, suggesting that it may be attributed to the effect of addition of Annona squamosa oil cake.

Abstract: Cypermethrin is a synthetic pyrethroid class of insecticide. Toxic effects of cypermethrin were explored by selecting Meretrix meretrix as an animal model. After acute (96 hours) exposure to Cypermethrin, tissues of Meretrix meretrix like gill, mantle, foot, hepatopancreas, male gonad and female gonad, were investigated for histological alterations. Pesticide stress showed histological changes, deterioration of tissue and damage at cellular and subcellular levels. There was remarkable damage in all tissues. Gills showed damage in epithelial cells and connective tissue in LC50 group. Mantle of clams from LC0 group showed considerable damage to the dorsal as well as ventral epithelium, connective tissues and blood spaces. Hepatopancreas of clams from LC50 group showed swelling of tubules. Male gonad showed severe damage; follicle wall was ruptured; sperms were clumped in a mass. Female gonad showed deterioration of ooplasmic material. LC50 group showed more damage than LC0 group. Foot of LC50 group shoed significant damage i.e. folding of marginal epidermis, shrinkage of epidermis, loss of connective tissues took lace as compared to control group of the clam. These histological changes were more prominent in gill and hepatopancreas as compared to other tissues.

Abstract: Groundwater is an important resource and the quality of groundwater has to be good for consumption purpose. Nitrate contamination in groundwater is a major problem in many places. Nitrate pollution in the groundwater of the Chennai coastal aquifers was assessed to find out the extent of pollution in the area. From the samples collected from various locations, it is identified that the concentration of nitrate in groundwater ranged between 9 mg/L and 106 mg/L, and 27.7% of the samples have high nitrate. It was found that the higher concentration of nitrate is due to the use of fertilizers and leaching from septic tanks of residential buildings in this region. It is evident from the present study that the groundwater of this area is highly contaminated with nitrate and mitigative measures are needed to be takne to treat the groundwater which is used for domestic purposes.
