Water pollution through urban and rural land use and freshwater allocation in New Zealand New Zealand has 425,000 kilometres of rivers and streams, almost 4,000 lakes larger than 1 hectare in size, and about 200 groundwater aquifers (Ministry for the Environment, 2010). By international standards, freshwater in New Zealand is both clean and in good supply. However, some aspects of water quality are getting worse in areas dominated by intensive land use. Demand for water is increasing, particularly

Wetlands are an integral part of the hydrological cycle which sustains diverse plants and animals, thereby, making wetlands the most fertile ecosystems on the planet. As a result, wetlands are considered one of the important sources of livelihood for the communities living near such wetlands. In India, wetland covers 5% of the geographical area and comprising of one fifth of its known biodiversity. In Assam, as per the estimated figures, approximately 7, 64,372 ha or 9.74% of country’s area is covered

second largest freshwater lake in the world, in East Africa, Lake Victoria, was the home of approximately 400 kinds of cichlids. Cichlids are fishes that are colorful. The species of cichlid that was in Lake Victoria had very different eating habits. Some nibbled on algae; others eat organic material that was dead at the deepest part of the lake; while others ate the insects, shrimp, and all the species of cichlids. These Cichlids blossomed all through the lake ecosystem and supplied protein

ladders[iv]. Moreover dams trap sediments that accumulate and concentrate the pollutants in the water retention basin (video about the polluted water). The lack of supply of new sediment downstream of the dam could cause erosion problems that affect aquatic environments, collapsing banks or nibble beaches. The Elwha River, located in the Northwest of the US used to be full of salmons before the construction of the dams and the salmons represent a resource non negligible that must be protected for the

managers. INTRODUCTION Coral reefs, one of the oldest ecosystems on Earth, are highly complex and often called “rainforests of the sea” because of the diversity of life forms they support (Connell, 1978; Secord, 2001). Coral reefs are important both economically and ecologically. It is estimated that they provide US$375 billion per year around the world in goods and services, with approximately 500 million people dependent on these ecosystems for food, materials, or income (Wilkinson, 2002).

the wetlands of southern Florida were an interconnected hydrological assortment of lavish freshwater lakes and streams, cypress swamps, secluded estuarine lagoons, freshwater sloughs, tree islands, wet prairies, and mangrove swamps spanning 3.6 million hectares. After a century of intrusion, the daunting task of understanding, fixing, maintaining, and regaining a sustainable, natural Everglades-type ecosystem in South Florida is monumental. The area south of Lake Okeechobee now has a human population
