Flexible Macroblock Ordering:

In this paper, we make use of the explicit assignment of macroblocks to slice groups to hide messages in the video stream. Since macroblocks can be arbitrary assigned to slice groups, we propose to use the slice group ID of individual macroblocks as an indication of message bits. Assume for instance that two slice groups are used, the allocation of a macroblock to slice group 0 indicates a message bit of 0 and the allocation of macroblock to slice group 1 indicates a message bit of 1. Hence, one message bit per macroblock can be carried.

Bio-Gas plant Visit


Biogas is an odorless, colorless gas commonly referred to as sewer gas.It is primarily made of methane, and 1,000 cubic feet of biogas can produce the same energy as 600 cubic feet of natural gas or 5.2 gallons of gasoline.A family of four may use 150 cubic feet of gas daily to power the appliances and lighting in their home.

USAGE OF BIOGAS PLANT:

A biogas plant converts biological waste into energy.It can use anything from livestock, chicken or human waste to agricultural compost or plant clippings. When these things decompose, they create methane.A biogas plant is a technology to capture these methane emissions and burn them to create more useful products.

Steps Involved in a Biogas Plant

  • Biogas is produced in several key stages that allow materials to decompose. A biogas plant is designed to take in biological matter and decompose it to produce useful gas, especially methane, which is a major component in natural gas that is mined from deposits.
  •  This methane can be used in similar devices to natural gas and does not deplete natural gas resources.
  • These plants are used to recycle waste from restaurants, farms and other places, or to provide developing nations with an alternative source of gas for heating and powering various appliances.
  • Biogas plants use a simple process to turn biomaterials in gas.

Working

  • The digester, shaped like a cube or a cylinder, has an inlet for slurry to enter it. The gas holder is made from steel and floats in the digester.
  • Its placement cuts off air to the digester, and the gas tank absorbs the emitted gas, sending it out of the plant through a pipe. Overflow from the digester is fed to the sludge receptacle.




Reduce co2 emission from Industry


Coal is the major fossil fuel used in industrial units and power plants for power generation in India.The carbon dioxide emitted as a product of combustion of coal (fossil fuels) is currently responsible for over 60% of the enhanced greenhouse effect.Combustion converts coal into useful heat energy, but it is also a part of the process that engenders the greatest environmental and health concerns.

Combustion of coal at thermal power plants emits mainly 
  • carbon dioxide (CO2)
  • sulphur oxides (SOx)
  • nitrogen oxides (NOx) and CFCs


other trace gases and air borne inorganic particulates, such as fly ash and suspended particulate matter (SPM).CO2, NOx and CFCs are green house gases (GHGs).   

There are three ways to reduce the CO2 emissions from a coal plant:


1. Fuel switching - replacing part or all of the fuel with a lower carbon fuel like biomass or natural gas (fuel switching)
2. Efficiency improvement - increasing the efficiency of the plant so less CO2 is emitted to produce the same output
3. Carbon Capture strategies – capturing the CO2 in the flue gas and storing it







Biodiversity action plan

Biodiversity:
Biodiversity encompasses the whole variety of life on Earth. It includes all species of plants and animals, but also their genetic variation, and the complex ecosystems of which they are part. It is not restricted to rare or threatened species but includes the whole of the natural world from the common place to the critically endangered.  The world is losing biodiversity at an ever-increasing rate as a result of human activity. On a world scale the rate of loss is now recognised to be a cause for serious concern, requiring concerted international action to prevent continued loss of the variety and totality of life on Earth. In the UK we have lost over 100 species during the last century, with many more species and habitats in danger of disappearing, especially at the local level. 
Benefits of biodiversity:
Biodiversity brings benefits to local communities through benefiting health, improving the local economy, maintaining environmental quality and ecosystem services and providing recreation and education resources for people of all ages. Therefore biodiversity cuts across many Local Authority activities.
Biodiversity Action Plan:
In situ conservation:
Expand the PA network of the country including Conservation and Community Reserves, to give fair representation to all biogeography zones of the country.  In doing so, develop norms for delineation of PAs in terms of the objectives and principles of the National Environment Policy, in particular, participation of local communities, concerned public agencies, and other stakeholders, who have direct and tangible stake in protection and conservation of wildlife, to harmonize ecological and physical features with needs of socio economic development. 

Establish self-sustaining monitoring system for overseeing the activities and effectiveness of the PA network.

Ensure that human activities on the fringe areas of PAs do not degrade the habitat or otherwise significantly disturb wildlife.

Mitigate man-animal conflicts.

Promote site-specific eco-development programmes in fringe areas of  PAs, to restore livelihoods and access to forest produce by local communities, owing to access restrictions in PAs.

Promote voluntary relocation of villagers from critical habitats of PAs.

Devise effective management and conservation techniques for the forest preservation plots to ensure conservation of representative areas of different forest types.

Strengthen research work on PAs, Biosphere Reserves and fragile ecosystems by involving local research institutions and universities, so as to develop baseline data on biological and managerial parameters, and functional properties of ecosystems.

Strengthen the protection of areas of high endemism of genetic resources (biodiversity hotspots), while providing alternative livelihoods and access to resources to local communities who may be affected thereby. 

Continue to promote inter-sectoral consultations and partnerships in strengthening biodiversity conservation activities.

Strengthen capacities and implement measures for captive breeding and release into the wild of identified endangered species.

Reintroduction and establishment of viable populations of threatened plant species.
Control poaching and illegal trade in wild animals and plant species.

Periodically revisits the norms, criteria and needs of data for placing particular species in different Schedules of the Wildlife (Protection) Act.

Promote ecologically and socially sensitive tourism and pilgrimage activities with emphasis on regulated and low impact tourism.

Promote ecologically and socially sensitive tourism and pilgrimage activities with emphasis on regulated and low impact tourism.

Formulate and implement partnerships for enhancement of wildlife habitat in Conservation Reserves and Community Reserves, on the lines of multistakeholder partnerships for afforestation, to derive both environmental and eco-tourism benefits. 
Promote conservation of biodiversity outside the PA network, on private property, on common lands, water bodies and urban areas.

Formulate and implement programmers for conservation of endangered species outside PAs.

Ensure conservation of ecologically sensitive areas, which are prone to high risk of loss of biodiversity due to natural or anthropogenic factors.

Ensure that survey and bioprospecting of native economically important biological resources is undertaken on a priority basis.

Integrate conservation and wise use of wetlands and river basic management involving all stakeholders, in particular local communities, to ensure maintenance of hydrological regimes and conservation of biodiversity.

Consider particular unique wetlands as entities of incomparable values, in developing strategies for their protection and formulate conservation and prudent use strategies for each of these, with participation of local communities, and other stakeholders

On-farm conservation
Identify hotspots of agro-biodiversity under different agro-ecozones and cropping systems and promote on-farm conservation.
Provide economically feasible and socially acceptable incentives such as value addition and direct market access in the face of replacement by other economically remunerative cultivars.
Develop appropriate models for on-farm conservation of livestock herds maintained by different institutions and local communities.
Develop mutually supportive linkages between in situ, on-farm and exsitu conservation programmes.

Ex situ conservation

Promote ex situ conservation of rare, endangered, endemic and insufficiently known floristic and faunal components of natural habitats, through appropriate institutionalization and human resource capacity building. For example, pay immediate heed to conservation and multiplication of rare, endangered and endemic tree species through revitalization of institutions such as Institute of Forest Genetics and Tree Breeding. 

Focus on conservation of genetic diversity (in situ, ex situ, in vitro) of cultivated plants, domesticated animals and their wild relatives to support their breeding programmes.

Develop cost effective and situation specific technologies for medium and long term storage of seed samples collected by different institutions and organizations.

Undertake DNA profiling for assessment of genetic diversity in rare, endangered and endemic species to assist in developing their conservation programmes. 

Develop a unified national database covering all ex situ conservation sites. 

Consolidate, augment and strengthen the network of ex situ centers of zoos, aquaria etc.

Develop networking of botanical gardens and consider establishing a Central Authority for botanic gardens to secure their better management,on the lines of Central Zoo Authority.

Provide for training of personnel and mobilize financial resources to strengthen captive breeding projects for endangered species of wild animals.

Strengthen basic research on reproduction biology of rare, endangered and endemic species to support reintroduction programmes.

Encourage cultivation of plants of economic value presently gathered from their natural populations, causing their decline. 

Promote inter-sectoral linkages and synergies to develop and realize full economic potential of ex situ conserved materials in crop and livestock improvement programmes.

Economically effective and socially viable incentives for conservation and sustainable use of biological diversity are being encouraged.  These include use of wood substitutes, alternative energy sources (biogas, wind mills, solar cookers, wave energy, fuel efficient stoves, etc.), establishment of nurseries, tree planting; stall feeding, water harvesting and pollution abatement measures.
The forestry sector in India is being re-defined with a growing emphasis on poverty alleviation and livelihood opportunities, while at the same time ensuring sustainable management and use of forest resources.   The current trend in forest management is towards greater participation and involvement of all stakeholders dependent on the forests.
In forest:
Production of wood and non-timber forest products, first for meeting subsistence needs and then the surplus for commercial purposes.
Protection and setting aside of areas to be managed as wild life reserves or plantations for recreational and environmental purposes.
Regulating the conversion of forest lands for non-forestry uses.
Regeneration of wastelands and degraded forests.
Functional and land capability classification of forests and land use planning to ensure healthy and sustainable land use systems with acceptable, safe minimum standards.
Protection of adequate extent of natural forests for their long-term contributions, including conservation of biodiversity.
Management and utilization of forest resources for maximizing their sustainable contribution and value addition towards improved welfare of society. 
Promotion of efforts for producing forest goods and services outside forest areas (e.g. agroforestry plantations, home gardens) and development of potential substitutes for wood from non-forest sources (e.g. rubber wood,coconut wood)
Waste reduction and waste recycling programme.
Feasible medium for encouraging participation of people and the private sector.
A proper and realistic system for cost, values and benefits attributable to forestry to ensure a strong ecology – economy interface.
Honey Bee Network is an important example to illustrate the measures taken to protect and encourage customary use of biological resources in India. 

Action Points:

Secure integration of biodiversity concerns into inter-sectoral policies and programmes to identify elements having adverse impact on biodiversity and design policy guidelines to address such issues. Make valuation of biodiversity an integral part of pre-appraisal of projects and programmes to minimize adverse impacts on biodiversity.

Promote decentralized management of biological resources with emphasis on community participation.

Promote sustainable use of biodiversity in sectors such as agriculture, animal husbandry, dairy development, fisheries, apiculture, sericulture, forestry and industry.

Debate on Nuclear power





Just 22% agreed that "nuclear power is relatively safe and an important source of electricity, and we should build more nuclear power plants". In contrast, 71% thought their country "could almost entirely replace coal and nuclear energy within 20 years by becoming highly energy-efficient and focusing on generating energy from the Sun and wind". Globally, 39% want to continue using existing reactors without building new ones, while 30% would like to shut everything down now.


Farm visit by TPM's




              

Organic foods are getting more popular among the world compare to the bigger consumption of conventional foods. There certain true organic foods may cost a bit more, but most of the peoplearket, organic foods are everywhere. There are clearly many benefits to organic foods, but there are specific like: it is healthier, protect the environment, different taste.
The organic farming and produce of organic foods has been prevalent from the time agriculture was first conceived. The natural way of growing crops started becoming unpopular and economically less feasible. More crop yields meant higher profits to the farmer and better agree, taste and quality are well worth compare to conventional. In today`s superm utilization of the land. The farmers who used fertilizers started growing two crops during the same time-period. That was the begging of fast growing industry of conventional foods. 
Organic foods are healthier than conventional in many aspects. The nutrients present in organic foods that are not in commercial foods. "Organic food for mineral levels, the researchers also looked for the amount of the heavy metals aluminum, cadmium, lead and mercury. Aluminum has been implicated for years in the development of Alzheimer's disease. It's content in organic food averaged 40% less that in commercial foods. Lead toxicity, which has been in the new a lot lately, can adversely affect our children's' IQ. It averaged 29% lower in organic foods. Mercury, which can cause neurologic damage, averaged 25% lower in organic foods" (Crinnion, Walter). The organic meat is healthier compare the conventional gown, full with antibiotics and many other chemicals for fast growing, which goes to us. The healthier means saver way of leaving. 
People consume more conventional food which evokes more farmers to use pesticides and to double their crops. The pesticides are dangerous for environment and wild life. People should buy more organic foods and lower the production of the conventional. That`s one of the ways to protect and safe the environment and wildlife of the world. Used chemicals kill different insects which are part of our ecosystem. Chemicals go from soil to the water reservoir and again back to us. 
The organic foods are proven to taste better and different than conventional grown foods. The organic food not only taste better, but doesn`t contains preservatives. The conventional milk, has inspiration date around 2 months compare to the organic one it`s not more than two weeks. The smell and the taste of organically grown tomatoes are totally different. 
The organic farms will continue to grow and produce more quality foods around the world. The healthier and long lasting life is connected with the consumption of more organic foods, which taste better and than the conventional. The organic farms help to reduce chemicals that are used for produce their crops. That's the way to save the environment and the wild life of the world.
