Environmental security
The protection of environment is needed for sustainable development. The Industrial pollution, degradation of forests, depletion of ozone layer, the green house gases results in global warming and climate which will have an adverse impact on environment and human health. There is a need for conservation of Biodiversity, protection of wetlands and prevention of environmental pollution, promotion of ecological balance enables sustainable development. There are several provisions provided in Indian Constitution for Protection of environment. There are certain legislations enacted viz. Environment Protection Act, Wildlife Preservation Act, Biodiversity Conservation Act, water and Air pollution prevention Acts etc The Judiciary playing a vital role in protection of Environment. Through Judicial Activism the Supreme Court can issue directions under writ Jurisdiction under Article 32 of Indian Constitution. The United Nation Organisation passed several UN conventions like Ramsar Convention on protection of wetlands, and UN convention on Biodiversity etc. World Environment Day is being celebrated across the world on 5th June every year.
Global Warming and Climate change
Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. Global warming is for real The average global temperatures are higher than they have ever been during the past millennium, and the levels of CO in the atmosphere have e crossed all previous records. The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and increasing extremities in weather patterns. Climate Change resulting from increased green house gases concentrations has the potential to harm societies and eco-systems. In particular, agriculture, forestry, water resources, human health, costal settlements and natural eco-systems will need to adapt to a changing climate or face diminishing functions. The changing climate patterns, and especially increased frequency and severity of extreme events, will increase vulnerability to the natural disasters, both slower on set ones such as drought and rapid onset disaster such as flood and cyclones.
Forest Conservation
The role of forests in the national economy and in ecology was emphasized in the 1988 National Forest Policy, which focused on ensuring environmental stability, restoring the ecological balance, and preserving the remaining forests. Other objectives of the policy were meeting the need for fuelwood, fodder, and small timber for rural and tribal people while recognizing the need to actively involve local people in the management of forest resources. Also in 1988, the Forest Conservation Act of 1980 was amended to facilitate stricter conservation measures. The 2009 Indian national forest policy document emphasizes the need to combine India’s effort at forest conservation with sustainable forest management. India defines forest management as one where the economic needs of local communities are not ignored; rather forests are sustained while meeting nation’s economic needs and local issues through scientific forestry.
Protection of Wetlands
Wetlands are complex ecosystems and encompass a wide range of inland, coastal and marine habitats. They share the characteristics of both wet and dry environments and show immense diversity based on their genesis, geographical location, hydrological regimes and substrate factors. They include flood plains, swamps, marshes, fishponds, tidal marshes natural and man-made wetlands. Among the most productive life support, wetlands have immense socio-economic and ecological importance for mankind. They are crucial to the survival of natural biodiversity. They provide suitable habitats for endangered and rare species of birds and animals, endemic plants, insects besides sustaining migratory birds. India has a wealth of wetland ecosystems distributed in different geographical regions. India is also a signatory to the Ramsar Convention on Wetlands and the Convention of Biological Diversity; Apart from government regulation, development of better monitoring methods is needed to increase the knowledge of the physical and biological characteristics of each wetland resource, and to gain, from this knowledge, a better understanding of wetland dynamics and their controlling processes. India being one of the mega diverse nations of the world should strive to conserve the ecological character of these ecosystems along with the biodiversity of the flora and fauna associated with these ecosystems. The Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. There are presently 158 Contracting Parties to the Convention, with 1758 wetland sites, totaling 161 million hectares, designated for inclusion in the Ramsar List of Wetlands of International Importance. Ramsar Convention is the only global environment treaty dealing with a particular ecosystem. The Ramsar Convention on Wetlands was developed as a means to call international attention to the rate at which wetland habitats were disappearing, due to lack of understanding of their important functions, values, goods and services. Governments which have joined the Convention are expressing their willingness to make a commitment for helping to reverse that history of wetland loss and degradation. In addition, many wetlands are international systems lying across the boundaries of two or more countries, or are part of river basins that include more than one country.
Conservation of Biodiversity
Conservation of Biodiversity is the need of the hour. The Biological Diversity Act, 2002 is a federal legislation enacted by the Parliament of India for preservation of biological diversity in India, and provides mechanism for equitable sharing of benefits arising out of use of traditional biological resources and knowledge. The Act was enacted to meet the obligations under Convention on Biological Diversity (CBD), to which India is a party. The National Biodiversity Authority (NBA) was established in 2003 to implement India’s Biological Diversity Act 2002. The NBA is a Statutory, Autonomous Body and it performs facilitative, regulatory and advisory function for the Government of India on issues of conservation, sustainable use of biological resources and fair and equitable sharing of benefits arising out of the use of biological resources.
Wildlife Conservation
Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans. Many nations have government agencies dedicated to wildlife conservation, which help to implement policies designed to protect wildlife. Numerous independent nonprofit organizations also promote various wildlife conservation causes. Wildlife conservation has become an increasingly important practice due to the negative effects of human activity on wildlife. Wildlife Conservation Act 2002 was enacted to protect wildlife in India. The main objective of Project Tiger is to ensure a viable population of tiger in India for scientific, economic, aesthetic, cultural and ecological values and to preserve for all time, areas of biological importance as a natural heritage for the benefit, education and enjoyment of the people. Project Elephant (PE), a centrally sponsored scheme, was launched in February 1992 to provide financial and technical support to major elephant bearing States in the country for protection of elephants, their habitats and corridors.
Ozone Depletion
Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth‘s stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens. The main source of these halogen atoms in the stratosphere is photo dissociation of man-made halocarbon refrigerants (CFCs, Subscribe on YouTube
