Hydroponics
Hydroponics (From the Greek words hydro, water and ponos, labor) is a method ofgrowing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants
may be grown with theirroots in the mineral nutrient solution only or in an inert medium,such as perlite, gravel, mineral wool, or coconut husk.
Researchers discovered in the 19th century that plants absorb essential mineral nutrientsas inorganic ionsin water. In natural conditions, soil acts as a mineral nutrient reservoir
but the soil itself is not essential to plant growth. When the mineral nutrients in the soil
dissolve in water, plant roots are able to absorb them. When the required mineral
nutrients are introduced into a plant's water supply artificially, soil is no longer requiredfor the plant to thrive. Almost any terrestrial plant will grow with hydroponics.
Hydroponics is also a standard technique in biology research and teaching.
Hydroponics culture is not new. One of the first experiments in water culture wasmade by Woodward in England in 1699. By the mid-19th century, Sachs and Knop,the real pioneers in the field, had developed a method of growing plants without soil.The term hydroponics was first used by Dr. W. F. Gericks in the late 1930s todescribe a method of growing plants with roots immersed in an aerated, dilutesolution of nutrients.Today, hydroponics is used in commercial greenhouse vegetable production aroundthe world. There are several advantages to hydroponics culture with some problems.In automated hydroponics culture, some of the watering and fertilizer additions canbecomputerized, reducing labor input.
Advantages of Hydroponics Land is not necessary. It can be practiced even in upstairs, open spaces and
in protected structures. Clean working environment. The grower will not have any direct contact withsoil. Low drudgery. No need of making beds, weeding, watering, etc. Continuous cultivation is possible. No soil borne diseases or nematode damage. Off-season production is possible. Vegetable cultivation can be done with leisure sense. Many plants were found to give yield early in hydroponics system. Higher yields possible with correct management practices. Easy to hire labour as hydroponics system is more attractive and easier than
cultivation in soil. No need of electricity, pumps, etc. for the non-circulating systems of solutionculture. Possibility of growing a wide variety of vegetable and flower crops includingAnthurium, marigolds, etc. Water wastage is reduced to minimum. Possible to grow plants and rooted cuttings free from soil particles for export.

Environmental management system (EMS) refers to the management of an
organization's environmental programs in a comprehensive, systematic, planned and
documented manner. It includes the organisational structure, planning and resources fordeveloping, implementing and maintaining policy for environmental protection.
An Environmental Management System (EMS):
Serves as a tool to improve environmental performance
Provides a systematic way of managing an organizations environmental affairs
Is the aspect of the organizations overall management structure that addresses
immediate and long-term impacts of its products, services and processes on the
environment
Gives order and consistency for organizations to address environmental concernsthrough the allocation of resources, assignment of responsibility and ongoing
evaluation of practices, procedures and processes
Focuses on continual improvement of the system
Environmental impact assessment
An environmental impact assessment (EIA) is an assessment of the possible positive or
negative impact that a proposed project may have on the environment, together consistingof the natural, social and economic aspects.
The purpose of the assessment is to ensure that decision makers consider the ensuing
environmental impacts when deciding whether to proceed with a project. The
International Association for Impact Assessment (IAIA) defines an environmental impact
assessment as "the process of identifying, predicting, evaluating and mitigating thebiophysical, social, and other relevant effects of development proposals prior to major
decisions being taken and commitments made."[1]. EIAs are unique in that they do notrequire adherence to a predetermined environmental outcome, but rather they require
decisionmakers to account for environmental values in their decisions and to justify those
decisions in light of detailed environmental studies and public comments on the potential
environmental impacts of the proposal[2].
EIAs began to be used in the 1960s as part of a rational decision making process. It
involved a technical evaluation that would lead to objective decision making. EIA was
made legislation in the US in the National Environmental Policy Act (NEPA) 1969. It has
since evolved as it has been used increasingly in many countries around the world. As perStephen J(2006) , EIA as it is practiced today, is being used as a decision aiding tool
rather than decision making tool. There is growing dissent on the use of EIA as its
influence on development decisions is limited and there is a view it is falling short of itsfull potential.There is a need for stronger foundation of EIA practice through training for
practitioners, guidance on EIA practice and continuing research[3].

The International Organization for Standardization (ISO) Standard 14011 covers EIA and
includes key steps for carrying out the assessment. These steps include the scope of EIA.
EIAs have often been criticized for having too narrow spatial and temporal scope. Atpresent no procedure has been specified for determining a system boundary for the
assessment. The system boundary refers to the spatial and temporal boundary of the
proposals effects. This boundary is determined by the applicant and the lead assessor,but in practice, almost all EIAs address the direct, on-site effects alone [4] .
However, as well as direct effects, developments cause a multitude of indirect effects
through consumption of goods and services, production of building materials and
machinery, additional land use for activities of various manufacturing and industrialservices, mining of resources etc . The indirect effects of developments are often an order
of magnitude higher than the direct effects assessed by EIA. Large proposals such as
airports or ship yards cause wide ranging national as well as international environmentaleffects, which should be taken into consideration during the decision-making process [5].
Broadening the scope of EIA can also benefit threatened species conservation. Instead ofconcentrating on the direct effects of a proposed project on its local environment some
EIAs used a landscape approach which focused on much broader relationships betweenthe entire population of a species in question. As a result, an alternative that would cause
least amount of negative effects to the population of that species as a whole, rather than
the local subpopulation, can be identified and recommended by EIA [6].
There are various methods available to carry out EIAs, some are industry specific andsome general methods:
Industrial products - Product environmental life cycle analysis (LCA) is used for
identifying and measuring the impact on the environment of industrial products.These EIAs consider technological activities used for various stages of theproduct: extraction of raw material for the product and for ancillary materials and
equipment, through the production and use of the product, right up to the disposal
of the product, the ancillary equipment and material[7].
Genetically modified plants - There are specific methods available to performEIAs of genetically modified plants. Some of the methods are GMP-RAM,
INOVA etc.[8]
Fuzzy Arithmetic - EIA methods need specific parameters and variables to be
measured to estimate values of impact indicators. However many of theenvironment impact properties cannot be measured on a scale eg landscape
quality, lifestyle quality, social acceptance etc. and moreover these indicators are
very subjective. Thus to assess the impacts we may need to take the help ofinformation from similar EIAs, expert criteria, sensitivity of affected population
etc. To treat this information, which is generally inaccurate, systematically, fuzzy
arithmetic and approximate reasoning methods can be utilised. This is called as afuzzy logic approach[9].

At the end of the project, an EIA should be followed by an audit. An EIA audit evaluates
the performance of an EIA by comparing actual impacts to those that were predicted. The
main objective of these audits is to make future EIAs more valid and effective. The twomain considerations are:
scientific - to check the accuracy of predictions and explain errors. management- to assess the success of mitigation in reducing impacts.
Some people believe that audits be performed as a rigorous scientific testing of the nullhypotheses. While some believe in a simpler approach where you compare what actually
occurred against the predictions in the EIA document[10].
After an EIA, the precautionaryandpolluter pays principlesmay be applied to prevent,
limit, or require strict liability orinsurance coverage to a project, based on its likelyharms. Environmental impact assessments are sometimes controversial.
E-Waste ManagementDefinition of e-waste :
Electronic waste, popularly known as e-waste can be defined as electronic equipments /
products connects with power plug, batteries which have become obsolete due to:
advancement in technologychanges in fashion, style and status
nearing the end of their useful life.
Classification of e-waste :
E-waste encompasses ever growing range of obsolete electronic devices such ascomputers, servers, main frames, monitors, TVs & display devices, telecommunicationdevices such as cellular phones & pagers, calculators, audio and video devices, printers,
scanners, copiers and fax machines besides refrigerators, air conditioners, washing
machines, and microwave ovens, e-waste also covers recording devices such as DVDs,CDs, floppies, tapes, printing cartridges, military electronic waste, automobile catalytic
converters, electronic components such as chips, processors, mother boards, printed
circuit boards, industrial electronics such as sensors, alarms, sirens, security devices,
automobile electronic devices.
Indian Scenario :
There is an estimate that the total obsolete computers originating from government
offices, business houses, industries and household is of the order of 2 million nos.
Manufactures and assemblers in a single calendar year, estimated to produce around 1200tons of electronic scrap. It should be noted that obsolence rate of personal computers
(PC) is one in every two years. The consumers finds it convenient to buy a new computer
rather than upgrade the old one due to the changing configuration, technology and theattractive offers of the manufacturers. Due to the lack of governmental legislations on e-

waste, standards for disposal, proper mechanism for handling these toxic hi-tech
products, mostly end up in landfills or partly recycled in a unhygienic conditions and
partly thrown into waste streams. Computer waste is generated from the individualhouseholds; the government, public and private sectors; computer retailers;
manufacturers; foreign embassies; secondary markets of old PCs. Of these, the biggest
source of PC scrap are foreign countries that export huge computer waste in the form ofreusable components.
Electronic waste or e-waste is one of the rapidly growing environmental problems of theworld. In India, the electronic waste management assumes greater significance not only
due to the generation of our own waste but also dumping ofe-waste particularly computer
waste from the developed countries.
With extensively using computers and electronic equipments and people dumping old
electronic goods for new ones, the amount ofE-Waste generated has been steadily
increasing. At present Bangalore alone generates about 8000 tonnes of computer waste
annually and in the absence of proper disposal, they find their way to scrap dealers.
E-Parisaraa, an eco-friendly recycling unit on the outskirts of Bangalore which is locatedin Dobaspet industrial area, about 45 Km north of Bangalore, makes full use ofE-Waste.
The plant which is Indias first scientific e-waste recycling unit will reduce pollution,
landfill waste and recover valuable metals, plastics & glass from waste in an eco-friendly
manner. E-Parisaraa has developed a circuit to extend the life of tube lights. The circuithelps to extend the life of fluorescent tubes by more than 2000 hours. If the circuits are
used, tube lights can work on lower voltages. The initiative is to aim at reducing the
accumulation of used and discarded electronic and electrical equipments.
India as a developing country needs simpler, low cost technology keeping in view of
maximum resource recovery in an environmental friendly methodologies. E-Parisaraa,deals with practical aspect ofe-waste processing as mentioned below by hand. Phosphor
affects the display resolution and luminance of the images that is seen in the monitor.
E-Parisaraas Director Mr. P. Parthasarathy, an IIT Madras graduate, and a former
consultant for a similar e-waste recycling unit in Singapore, has developed an eco-
friendly methodology for reusing, recycling and recovery of metals, glass & plastics with
non-incineration methods . The hazardous materials are segregated separately and sendfor secure land fill for ex.: phosphor coating, LEDs, mercury etc.
We have the technology to recycle most of the e-waste and only less than one per cent ofthis will be regarded as waste, which can go into secure landfill planned in the vicinity by
the HAWA project.
Carbon credit

6/25
A carbon credit is a generic term for any tradable certificate or permit representing the
right to emit one tonne of carbon dioxide or carbon dioxide equivalent (CO2-e).[1][2][3]
Carbon credits and carbon markets are a component of national and international attemptsto mitigate the growth in concentrations ofgreenhouse gases(GHGs). One carbon credit
is equal to one ton of carbon dioxide, or in some markets, carbon dioxide equivalentgases. Carbon trading is an application of an emissions trading approach. Greenhouse gas
emissions are capped and then markets are used to allocate the emissions among thegroup of regulated sources. The goal is to allow market mechanisms to drive industrial
and commercial processes in the direction of low emissions or less carbon intensive
approaches than those used when there is no cost to emittingcarbon dioxideand otherGHGs into the atmosphere. Since GHG mitigation projects generate credits, this
approach can be used to financecarbon reduction schemesbetween trading partners and
around the world.
There are also many companies that sell carbon credits to commercial and individual
customers who are interested in lowering theircarbon footprinton a voluntary basis.These carbon offsetters purchase the credits from an investment fund or a carbon
development company that has aggregated the credits from individual projects. Thequality of the credits is based in part on the validation process and sophistication of the
fund or development company that acted as the sponsor to the carbon project. This is
reflected in their price; voluntary units typically have less value than the units soldthrough the rigorously validated Clean Development Mechanism.
ISO
ISO stands for the International Organization for Standardization, located in Geneva,Switzerland. ISO is a non-governmental organization established in 1947. The
organization mainly functions to develop voluntary technical standards that aim atmaking the development, manufacture and supply of goods and services more efficient,safe and clean.

Global warming
Global warming is the increase in the average temperatureofEarth's near-surface air
and oceans since the mid-20th century and its projected continuation. According to the2007 Fourth Assessment Reportby the Intergovernmental Panel on Climate Change(IPCC), global surface temperature increased 0.74 0.18 C(1.33 0.32 F) during the
20th century.[2][A] Most of the observed temperature increase since the middle of the 20th
century has been causedby increasing concentrations ofgreenhouse gases, which resultfrom human activity such as the burning offossil fuel and deforestation.[3]Global
dimming, a result of increasing concentrations of atmospheric aerosols that block sunlight
from reaching the surface, has partially countered the effects of warming induced by
greenhouse gases.
Climate model projections summarized in the latest IPCC report indicate that the global
surface temperature is likely to rise a further 1.1 to 6.4 C (2.0 to 11.5 F) during the 21st
century.[2] The uncertainty in this estimate arises from the use of models with differingsensitivity to greenhouse gas concentrationsand the use of differing estimates of future
greenhouse gas emissions. An increase in global temperature will cause sea levels to rise
and will change the amount and pattern ofprecipitation, probably including expansion of
subtropicaldeserts.[4] Warming is expected to be strongest in the Arctic and would beassociated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects
include changes in the frequency and intensity ofextreme weatherevents, species

extinctions, and changes in agricultural yields. Warming and related changes will vary
from region to region around the globe, though the nature of these regional variations is
uncertain.[5] As a result of contemporary increases in atmospheric carbon dioxide, theoceans have becomemore acidic, a result that is predicted to continue. [6][7]
The scientific consensusis that anthropogenic global warming is occurring.[8][9][10][B]
Nevertheless, politicalandpublic debate continues. TheKyoto Protocolis aimed at
stabilizing greenhouse gas concentration to prevent a "dangerous anthropogenicinterference".[11] As of November 2009, 187 states had signed and ratified the protocol
Ecolabel
Ecolabels and Green Stickers are labelling systems for food and consumer products.Ecolabels are often voluntary, but Green Stickers are mandated by law in North America
for major appliances and automobiles. They are a form ofsustainability measurement
directed at consumers, intended to make it easy to take environmental concerns intoaccount when shopping. Some labels quantify pollution or energy consumption by way of
index scores or units of measurement; others simply assert compliance with a set of
practices or minimum requirements for sustainability or reduction of harm to the
environment. Usually both the precautionary principle and thesubstitution principleareused when defining the rules for what products can be ecolabelled.[citation needed]
Ecolabelling systems exist for both food and consumer products. Both systems were
started by NGOs but nowadays the European Union have legislationfor the rules of
ecolabelling and also have their own ecolabels, one for food and one for consumerproducts. At least for food, the ecolabel is nearly identical with the common NGO
definition of the rules for ecolabelling. Trust in the label is an issue for consumers, asmanufacturers or manufacturing associations could set up "rubber stamp" labels togreenwashtheir products.
Many people believe that most food ecolabels are the same as organic labelling. This is
not inaccurate, a great many certification standards with ecolabels exist, such as
Rainforest Alliance, Utz coffee, cocoa and tea, GreenPalm, Marine Stewardship Council,and many more; these are aimed at sustainable food production and good social and
environmental performance. These are mainstream standards aimed at improving whole
sectors of the food industry, in addition there are many more of these which are business-to-business standards that do not carry consumer-facing ecolabels.

environmental management system as such and therefore does not dictate absolute
environmental performance requirements (National Academy Press 1999), but serves
instead as a framework to assist organisations in developing their own environmentalmanagement system (RMIT University). ISO 14001 can be integrated with other
management functions and assists companies in meeting their environmental and
economic goals.
ISO 14001, as with other ISO 14000 standards, is voluntary (IISD 2010), with its mainaim to assist companies in continually improving their environmental performance,
whilst complying with any applicable legislation. Organisations are responsible for
setting their own targets and performance measures, with the standard serving to assistthem in meeting objectives and goals and the subsequent monitoring and measurement of
these (IISD 2010). This means that two organisations that have completely different
measures and standards of environmental performance, can both comply with ISO 14001requirements (Federal Facilities Council Report 1999).
The standard can be applied to a variety of levels in the business, from organisationallevel, right down to the product and service level (RMIT university). Rather than
focusing on exact measures and goals of environmental performance, the standardhighlights what an organisation needs to do to meet these goals (IISD 2010). Success of
the system is very dependant on commitment from all levels of the organisation,
especially top management (Standards Australia/Standards New Zealand 2004), whoneed to be actively involved in the development, implementation and maintenance of the
environmental management system (iso14001.com.au 2010). In 2008 there were an
estimated 188 000 companies from 155 countries, certified as ISO 14001 compliant
(ISO14001.com.au 2010)
ISO 14001 is known as a generic management system standard, meaning that it isapplicable to any size and type of organisation, product or service, in any sector of
activity and can accommodate diverse socio-cultural and geographic conditions
(Standards Australia/Standards New Zealand 2004). All standards are periodicallyreviewed by ISO and new ones issued (Standards Australia/Standards New Zealand
2004).
[edit] Basic principles and methodology
The fundamental principle and overall goal of the ISO 14001 standard, is the concept of
continual improvement (Federal Facilities Council Report 1999). ISO 14001 is based on
the Plan-Do-Check-Act methodology (Standards Australia/Standards New Zealand 2004)which has been expanded to include 17 elements, grouped into five phases that relate toPlan-Do-Check-Act; Environmental Policy, Planning, Implementation & Operation,
Checking & Corrective Action and lastly Management Review (Martin 1998).

[edit] Plan establish objectives and processes required
Prior to implementing ISO 14001, an initial review or gap analysis of the organisations
processes and products is recommended, to assist in identifying all elements of thecurrent operation and if possible future operations, that may interact with the
environment, termed environmental aspects (Martin 1998). Environmental aspects caninclude both direct, such as those used during manufacturing and indirect, such as raw
materials (Martin 1998). This review assists the organisation in establishing theirenvironmental objectives, goals and targets, which should ideally be measurable; helps
with the development of control and management procedures and processes and serves to
highlight any relevant legal requirements, which can then be built into the policy(Standards Australia/Standards New Zealand 2004).
Greenhouse effectThe greenhouse effect is a process by which thermal radiation from a planetary surfaceis absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since
part of this re-radiation is back towards the surface, energy is transferred to the surface
and the lower atmosphere. As a result, the temperature there is higher than it would be ifdirect heating by solar radiation were the only warming mechanism.[1][2]
This mechanism is fundamentally different from that of an actual greenhouse, which
works by isolating warm air inside the structure so that heat is not lost by convection.
The greenhouse effect was discovered by Joseph Fourierin 1824, first reliablyexperimented on by John Tyndallin 1858, and first reported quantitatively by SvanteArrhenius in 1896.[3]
If an ideal thermally conductive blackbodywas the same distance from the Sun as the
Earth is, it would have a temperature of about 5.3 C. However, since the Earth reflects
about 30%[4] (or 28%[5]) of the incoming sunlight, the planet's effective temperature (thetemperature of a blackbody that would emit the same amount of radiation) is about 18
or 19 C,[6][7] about 33C below the actual surface temperature of about 14 C or 15 C.[8] The mechanism that produces this difference between the actual surface temperatureand the effective temperature is due to the atmosphere and is known as the greenhouse
effect.
Global warming, a recent warming of the Earth's surface and lower atmosphere,[9] is
believed to be the result of a strengthening of the greenhouse effect mostly due to human-produced increases in atmospheric greenhouse gases.[10

The ozone layer is a layer inEarth's atmosphere which contains relatively high
concentrations ofozone (O3). This layer absorbs 9799% of theSun's high frequency
ultraviolet light, which is damaging to life on Earth. [1] It is mainly located in the lowerportion of the stratosphere from approximately 13 to 40 kilometres (8.1 to 25 mi) above
Earth, though the thickness varies seasonally and geographically.[2] The ozone layer was
discovered in 1913 by the French physicistsCharles FabryandHenri Buisson. Itsproperties were explored in detail by the British meteorologistG. M. B. Dobson, who
developed a simple spectrophotometer(theDobsonmeter) that could be used to measure
stratospheric ozone from the ground. Between 1928 and 1958 Dobson established aworldwide network of ozone monitoring stations, which continue to operate to this day.
The "Dobson unit", a convenient measure of the columnar density of ozone overhead, is
named in his honor.
Origin of ozone
The photochemical mechanisms that give rise to the ozone layer were discovered by the
British physicistSidney Chapman in 1930. Ozone in the Earth's stratosphere is created byultraviolet lightstriking oxygenmolecules containing two oxygen atoms (O2), splittingthem into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines
with unbroken O2 to create ozone, O3. The ozone molecule is also unstable (although, in
the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule
of O2 and an atom of atomic oxygen, a continuing process called the ozone-oxygen cycle,thus creating an ozone layer in thestratosphere, the region from about 10 to 50 kilometres
(33,000 to 160,000 ft) above Earth's surface. About 90% of the ozone in our atmosphere
is contained in the stratosphere. Ozone concentrations are greatest between about 20 and40 kilometres (12 and 25 mi), where they range from about 2 to 8 parts per million. If all
of the ozone were compressed to the pressure of the air at sea level, it would be only a
few millimeters thick.
Food chain
Food chains and food webs are representations of the predator-preyrelationships
between species within an ecosystem orhabitat.
Many chain and web models can be applicable depending on habitat orenvironmental
factors. Every known food chain has a base made ofautotrophs, organisms able tomanufacture their own food (e.g. plants,chemotrophs).
Organisms represented in food chains
In nearly all food chains, solar energy is input into the system as light and heat, utilized
by autotrophs (i.e., producers) in a process called photosynthesis. Carbon dioxide isreduced (gains electrons) by being combined with water (a source of hydrogen atoms),
producing glucose. Water splitting produces hydrogen, but is a nonspontaneous
(endergonic) reaction requiring energy from the sun. Carbon dioxide and water, both

stable, oxidized compounds, are low in energy, but glucose, a high-energy compound and
good electron donor, is capable of storing the solar energy.[1] This energy is expended for
cellular processes, growth, and development. The plant sugars are polymerizedforstorage as long-chain carbohydrates, including other sugars, starch, and cellulose.
Glucose is also used to make fatsand proteins.[2]
Proteins can be made using nitrates,sulfates, and phosphatesin the soil.[3] When autotrophs are eaten by heterotrophs, i.e.,
consumers such as animals, the carbohydrates,fats, and proteins contained in thembecome energy sources for the heterotrophs.[2]
The food chain consists of four main parts:
The Sun, which provides the energy for everything on the planet.
Producers: these include all green plants. These are also known as autotrophs,
since they make their own food. Producers are able to harness the energy of thesun to make food. Ultimately, every (aerobic) organism is dependent on plants
for oxygen (which is the waste product from photosynthesis) and food (which isproduced in the form of glucose through photosynthesis). They make up the bulkof the food chain or web.
Consumers: In short, consumers are every organism that eats something else.
They include herbivores (animals that eat plants), carnivores (animals that eat
other animals), parasites (animals that live off of other organisms by harming it),and scavengers (animals that eat dead animal carcasses). Primary consumers are
the herbivores, and are the second largest biomass in an ecosystem. The animals
that eat the herbivores (carnivores) make up the third largest biomass, and are alsoknown as secondary consumers. This continues with tertiary consumers, etc.
Decomposers: These are mainly bacteria and fungi that convert dead matter into
gases such as carbon and nitrogen to be released back into the air, soil, or water.Fungi, and other organisms that break down dead organic matter are known as
saprophytes. Even though most of us hate those mushrooms or molds, they
actually play a very important role. Without decomposers, the earth would becovered in trash. Decomposers are necessary since they recycle the nutrients to
be used again by producers.
Eco hotels
WHAT ARE ECO HOTELS?
Eco hotel is used to describe a hotel that is enviornment friendly.
The basic definition of a green hotel is an environmentally-responsible lodging that follows the practices of green living.
These hotels have to be certified green by an independent third-partyor by the state they are located in.

Traditionally, these hotels were mostly presented as Eco Lodges becauseof their location, often in jungles, and their design inspired by the use oftraditional building methods applied by skilled local craftsmen in areas,such as Costa Rica and Indonesia.
Today, the term has developed to include properties in less naturallocations that have invested in improving their green credentials.
CRITERIA FOR AN ECO HOTEL
An eco hotel must usually meet the followingcriteria
Dependence on the natural environment Ecological sustainability Proven contribution to conservation Provision of environmental training programs
Incorporation of cultural considerations Provision of an economic return to the local community
Characteristics of eco-hotel
Green hotels follow strict green guidelines to ensure that their guests arestaying in a safe, non-toxic and energy-efficient accommodation. Here aresome basic characteristics of a green hotel:
Housekeeping uses non-toxic cleaning agents and laundry detergent
100% organic cotton sheets, towels and mattresses
Non-smoking environment Energy-efficient lighting
Serve organic and
local-grown food
Non-disposable dishes

IMPACT OF TOURISM AND TRAVEL
These are environmentally-friendly, energy conserving, non toxicand recyclable. Environmentally friendly hotels
They not only save money for the owner and guests, but alsoresources for the world.
Thus many of tourists will be attracted to a green hotel just becauseit is taking environmentally friendly steps. Organizations like the

Carbon Bank
"Carbon Bank" is a term used to describe the international effort to reduce carbongas emissions (Carbon dioxide, Methane, CFC's etc) which may contribute to
global warming. An industrialized nation may produce more than its share and a
less developed nation may be provided incentives for not destroying its rainforests such as food aid and so on, since plant life, and especially the very rich
plant life of the tropical rain forests removes carbon dioxide from the air by
photosynthesis.

continuous movement of water on, above and below the surface of the Earth. Water canchange states among liquid,vapour, and ice at various places in the water cycle.
Although the balance of water on Earth remains fairly constant over time, individual
water molecules can come and go, in and out of the atmosphere. The water moves from
one reservoir to another, such as from river to ocean, or from the ocean to theatmosphere, by the physical processes of evaporation, condensation, precipitation,
infiltration, runoff, and subsurface flow. In so doing, the water goes through different
phases: liquid, solid, and gas.
The hydrologic cycle also involves the exchange of heat energy, which leads to
temperature changes. For instance, in the process of evaporation, water takes up energy
from the surroundings and cools the environment. Conversely, in the process of
condensation, water releases energy to its surroundings, warming the environment.
The water cycle figures significantly in the maintenance of life and ecosystems on Earth.
Even as water in each reservoir plays an important role, the water cycle brings added
significance to the presence of water on our planet. By transferring water from one
reservoir to another, the water cycle purifies water, replenishes the land with freshwater,and transports minerals to different parts of the globe. It is also involved in reshaping the
geological features of the Earth, through such processes as erosion and sedimentation. Inaddition, as the water cycle involves heat exchange, it exerts an influence on climate aswell.
Coastal Land Management-australia
Coastal Responsibilities
The Borough acts as the Crown Land Manager for most foreshore areas within the
Borough on behalf of the Department of Sustainability and Environment. Themanagement of the coast and foreshore areas is therefore a responsibility shared byCouncil with the State Government.
A Queenscliffe Coastal Management Plan has been developed to provide guidance on
Coastal Management in the Borough of Queenscliffe. The plan can be downloaded on

This plan is underpinned by the Victorian Coastal Strategy (VCS), which provides a
long-term vision for the planning, management and sustainable use of our coast, and the
policies and actions Victorians will need to implement over the next five years to helpachieve that vision.
It identifies and responds to three significant issues affecting Victorias coast that requirespecific attention:
Climate Change
Population and Growth
Marine Ecological Integrity
The Victorian Coastal Strategy 2008 is established under the Coastal Management Act
1995, and is the third VCS to be produced since 1997 they are reviewed every fiveyears. The VCS can be downloaded on this page.
Foreshore Reserves
The Council, in conjunction with the Department of Sustainability and Environment,
manage and maintain numerous reserves located along the bayside beaches and the surf
beach at Point Lonsdale.
From the sensitive shores of Swan Bay, to the pleasant bayside beaches of Queenscliff
and Point Lonsdale, to the rugged face of Bass Strait at Point Lonsdale's surf beach, the
features, flora and fauna are a treat for the locals and visitors alike.
Water (Prevention and Control of Pollution) Cess Act
The Water (Prevention and Control of Pollution) Cess Actwas enacted in 1977, toprovide for the levy and collection of a cess on water consumed by persons operating and
carrying on certain types of industrial activities. This cess is collected with a view toaugment the resources of the Central Board and the State Boards for the prevention and
control of water pollution constituted under the Water (Prevention and Control of
Pollution) Act, 1974. The Act was last amended in 2003.
Furnishing of Water Consumption Return
Under the provisions of the Water (Prevention & Control of Pollution) Cess Act, 1977,
every person carrying on a specified industry (Annexure-I) and every local authority is
required to furnish a return on Form-I (Annexure-II) showing the quantity of water
consumed in a month on or before the 5th of the following month to the concernedRegional Office of the Board for onward transmission to the Assessing Authority
(Member Secretary).

In the case the industry/local body fails to furnish the returns, the said authority shall,
after making such inquiry as it deems fit by order, self assess the amount of cess payable
by the concerned persons for carrying on of any specified industry or local authority, atthe rate as shown in (Annexure-III) as the case may be.
The industry/local authority is required to pay cess amount within a period of 45/30 daysfrom the date of assessment order, failing which interest @ 2% per month, on the amount
of cess is payable. The assessing authority may also levy a penalty equivalent to theamount of cess not paid by the due date.
Where any person or local authority liable to pay cess under this Act installs any plant for
the treatment of sewage or trade effluent, such person or local authority shall from suchdate be entitled to rebate of 25% of the cess payable by such person or, as the case may
be, local authority.
Provided that a person or local authority shall not be entitled to the said rebate, if he or it
consumes water in excess of the maximum quantity as may be prescribed (Annexure-IV)
for any specified industry or local authority or fails to comply with any of the provisionsof Section 25 of the Water (Prevention & Control of Pollution) Act, 1974 or any of the
standards laid down by the Central Government under the Environment (Protection) Act,1986.

ENVIRONMENTAL LEGISLATION
Legislative Environment
The Indian Constitution provides necessary directives and powers for framing and enforcing
environmental legislation. The Ministry of Environment and Forests (MoEF), the Central
Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) form theregulatory and administrative core.
6.1.1 Administrative Issues
The powers of the Environment (Protection) Act have been exercised by theCentral Government through the Ministry of Environment and Forests (MoEF).
However, the monitoring mechanism for implementation of the Act is stillundefined, although for the various regulations enforcement institutions have
been enlisted. Also in several areas of environmental concern, such asvehicular-pollution control, the MoEF has no decisive role, since it is
implemented by a separate Ministry through the Motor Vehicles Act.
In general, environmental issues are on the concurrent list which means that
they are included in jurisdiction of both Central and State Governments. Thelocal bodies, in turn, have certain responsibilities. Central Government gives
the policy guidelines, but the implementation of environmental laws and
regulations is a state responsibility. Every state and union territory has a
Department of Environment. States also have the State Pollution Control Board(SPCB) whose activities are coordinated by the CPCB. The SPCB can be seen
as an executing agency of the Department of Environment together theymanage the implementation of environmental laws on a state level. Apart from
coordinating the activities of SPCBs the CPCB is advising the Central
Government in all the matters related to protection of environment. As it is
stated in the Constitution of India, it is the duty of the state (Article 48 A) to
protect and improve the environment and to safeguard the forests and wildlifeof the country.
The major instrument with the State to check environmental degradation is
undoubtedly regulation. The country has adopted almost all environmentalprotection Acts and rules enforced in developed countries. The government has
formulated comprehensive legislation to enable the institutions like pollutioncontrol boards to effectively protect the environment. There are around 30 acts

The legislation on environmental and pollution control related issues is extensive andverymuch industry specific.
The most important Act is The Environment (Protection) Act, 1986. The Environment
(Protection) Act, 1986 intends to achieve the place of umbrella legislation by providing
solution to virtually every kind of environmental problems through appointment ofauthorities and rule-making mechanism. It also aims at coordinating the activities of various
Central and State Authorities established under previous enactments like Water and Air Acts.
The Environment (Protection) Act, consisting of 26 sections distributed in four chapters, for
instance prohibits persons carrying on industry operation etc. from discharging or any
environmental pollutants in excess of the prescribed standards. Further, the statute permits
handling of hazardous substance only in accordance with the procedure and after complyingwith such safeguards that are prescribed for the same. The Act provides for penalties
(including imprisonment) in cases of contravention of the provisions.
The concentration of powers in the central government is the hallmark of the Environment
Act: Extensive powers have been given to the central Government for prevention, control andabatement of environmental pollution. The Central Government can, by notification in
the official Gazette, introduce new environment-related standards, restrictions and
prohibitions.
Some of the important rules made under the Act include:
The Environment (Protection) Rules, 1986
The Hazardous Wastes (Management and Handling) Rules, 1989
The Manufacture, Storage and Import of Hazardous Chemical Rules, 1989
The Hazardous Micro-Organism Rules, 1989
The Chemical Accident (Emergency Planning, Preparedness and Response)
Rules, 1996
The Bio-Medical Waste (Management and Handling) Rules, 1998
The Recycled Plastics Manufacture and Uses Rules, 1999
The Municipal Solid Waste (Management and Handling) Rules, 2000
The Noise Pollution (Regulation and Control) Rules, 2000
The Ozone Depleting Substances (Regulation and Control) Rules, 2000.
Out of these the Environment (Protection) Rules, 1986 cover the widest array
of issues. The Rules lay down procedures for setting standards for emissionsand discharge of environmental pollutants and introduce standards for
numerous industries (totally 86). Subsequently CPCB has identified 17
categories of major polluting industries2 for which action plans have beenformulated and standards introduced.
Besides the aforesaid existing procedural Rules framed under the parent Act,
there are various quasi-laws like
Emission Standards as per Air Act, 1981
Emission Standards for Automobiles for Prevention and Control of Pollution.
