A vulnerability assessment A
vulnerability assessment is the process of identifying,
quantifying, and prioritizing (or ranking) the
vulnerabilities
in a system. Examples of systems for which vulnerability assessments are
performed include, but are not limited to, information technology systems,
energy supply systems, water supply systems, transportation systems, and
communication systems. Such assessments may be conducted on behalf of a range
of different organizations, from small businesses up to large regional infrastructures.
Vulnerability from the perspective of disaster management means assessing the
threats from potential hazards to the population and to infrastructure. It may
be conducted in the political, social, economic or environmental fields.

The area of land draining into a stream or a water course at a given location is known as catchment area or Drainage area or Drainage basin.
CENSUS DEFINITIONThe basic unit for rural areas is revenue village, which has definite surveyed boundaries. The revenue village may comprise several hamlets, but the entire village has been treated as one unit .In un-surveyed areas like settlements within forest areas, each habitation area with locally recognised boundaries within each forest range officer's area was treated as one unit.
The following criteria were adopted for treating a place as urban in 1991 Census:
(a) All statutory towns i.e. all places with a municipality, corporation, cantonment board or notified town area committee, etc.
(b) All other places which satisfied the following criteria:
(i) A minimum population of 5,000
(ii) At least 70% of the male working population engaged in non-agricultural pursuits
(iii) A density of population of at least 400 persons per sq. km. (1000 per sq. mile)
Note:
A town with a population of one hundred thousand and above is generally referred to as a 'city'. The urban criteria of the 1981 and 1991 censuses varied slightly from that of the 1961 and 1971 censuses. The workers in occupations of forestry, fishing, livestock, hunting, logging, plantations and orchards etc. (falling in industrial category III) were treated as non- agricultural activities in 1961 and 1971 census whereas in 1981 and 1991 censuses, these activities have been treated as agricultural activities for the purpose of determining the male working population in non-agricultural pursuits.
The urbanised outgrowths of the cities and towns have also been treated as urban. In several areas around a core city or a statutory town fairly large well-recognised railway colony, university campus, port area, military camp etc, might have come up. Even id such places are lying outside the statutory limits
of the corporation, municipality or cantonment, etc, in most cases they fall within the revenue limits of
the village or villages, which is or are contiguous to the town. Since such areas are already urbanized, it is not considered realistic to treat such areas lying outside the statutory limits of a town as rural units, although a few of them may not satisfy some of the prescribed eligibility tests to qualify themselves as independent urban units. Such areas have been termed as 'outgrowth' (OG's) and reckoned along with
the town . Each such town together with its out-growth is treated as an integrated urban area and is designated as 'urban agglomeration'(U.A) therefore constitutes:
(i) A city or a town with a continuos outgrowth, the outgrowth being outside the statutory limits but falling within the boundaries of the adjoining villages or
(ii) Two or more adjoining towns with their outgrowths, if any as in (I) above or
(iii) A city and one or more adjoining towns with or without outgrowths all of which form a continuous spread.
The concept of urban agglomeration (U.A) was adopted for the first time in 1971 census and continued in 1981 and 1991 censuses.
Census houseIs a building or part of a building having a separate main entrance from the road or common courtyard or staircase etc, used or recognised as a separate unit. It may be occupied or vacant. It may be used for residential or non- residential purpose or both

Emission Factor: Emission Factor: For stationary sources, the relationship between the amount of pollution produced and the amount of raw material processed or burned. For mobile sources, the relationship between the amount of pollution produced and the number of vehicle miles traveled. By using the emission factor of a pollutant and specific data regarding quantities of materials used by a given source, it is possible to compute emissions for the source. This approach is used in preparing an emissions inventory.

standards. This is seen as a form of corporate
social responsibility allowing
companies to address their obligation to minimise the harmful impacts to the
environment by voluntarily following a set of externally set and measured
objectives.

1965 during theConstitutive Assembly of ICOMOS,2 the scope of heritage was
redefined. Heritage wasthen defined as monuments and sites:
Article
3:1
The
term monument shall include all real property, … whether they contain buildings
or not, having archaeological, architectural, historic or ethnographical
interest and may include besides the furnishing preserved within them
The

HouseIn the context of planning, 'house' means a building for human habitation. It can take many forms, a mud-hut with a single room to a place with 500 rooms. For modern planning, the majority of houses are either one, two or three storey single-family dwellings and either detached, semi-detached or terraced i.e., structurally joined in rows of three or more. Except in housing statistics, the term is not usually applied to single-floor dwellings in multi-storey building; these are called 'apartments' in USA and most European countries and 'flats' in Great Britain.
HouseholdA household is a group of persons who commonly live together and would take their meals from the common kitchen unless the exigencies of work prevent any of them from doing so. There may be households of persons related by blood or a household of unrelated persons or mix of both.

Rainwater harvestingWater in the atmosphere can be tapped through the condensation of mist or air moisture of through ran-catchment. The former sources have proved feasible where other sources are not available. The interception of rainwater before it reaches the ground has the advantage that the water may collect with minimum contamination. The amount of water, which can be collected, is determined by the amount of rainfall and the size of the collection area. Rainwater can be harvested on roof or ground. Contamination with bird droppings, dust and other deposits on the roof can be overcome by the installation of simple devices to separate the first flush of water from remainder to be stored. Ground catchments are ideal for collecting surface run-off which require a degree of protection to prevent gross pollution of the water.

R-Value The R-value is a measure of thermal
resistance used in the
building and construction industry.
Under uniform conditions it is the ratio of the temperature difference across
an insulator and the heat flux (heat
transfer per unit area per unit time, ) through it or . The R-value being discussed is the unit thermal
resistance. This is used for a unit value of any particular material. It is
expressed as the thickness of the material divided by the thermal
conductivity. The higher the number, the better the building insulation's
effectiveness. R-value is the reciprocal of U-factor.

U-factor The U-factor or "U-value", is the overall
heat transfer coefficient that
describes how well a building element conducts heat or the rate of transfer of
heat (in watts) through one square metre of a structure divided by the
difference in temperature across the structure. The elements are commonly
assemblies of many layers of components such as those that make up
walls/floors/roofs etc. It measures the rate of heat transfer through a
building element over a given area under standardised conditions. The usual
standard is at a temperature gradient of 24 °C (75 °F), at 50% humidity with no wind (a smaller U-factor is better at reducing heat transfer).
It is expressed in watts per metres squared kelvin, or W/m²K. This means that
the higher the U value the worse the thermal performance of the building
envelope. A low U value usually indicates high levels of insulation. They are
useful as it is a way of predicting the composite behaviour of an entire
building element rather than relying on the properties of individual materials.
Unidirectional Externality These are externalities in which the external costs or benefits of the resource use are 'one way'.
Urban acupuncture
