Shelter and site planning
Introduction
Refugees arriving in any specific area tend to
settle down in different ways: often, they concentrate on an unoccupied
site and create a 'camp'; at other times, they spread out over a wide area
and establish rural settlements; and sometimes they are hosted by local
communities (rural or urban). The latter two situations, also called 'open
situations', occur less frequently than the first (see below and the
Introduction to Part II).
A poorly planned refugee settlement is one of the most
pathogenic environments possible. Overcrowding and poor hygiene are major
factors in the transmission of diseases with epidemic potential (measles,
meningitis, cholera, etc.). The lack of adequate shelter means that the
population is deprived of all privacy and constantly exposed to the
elements (rain, cold, wind, etc.). In addition, the surrounding
environment may have a pronounced effect on refugee health, particularly
if it is very different from the environment from which they have come
(e.g. presence of vectors carrying diseases not previously encountered).
Camps usually present a higher risk than refugee
settlements in open situations as there is more severe overcrowding, and
less likelihood that basic facilities, such as water supply and health
care services, will be available when refugees first arrive2,7. Relief
work is more difficult to organize for very large camp populations, such
as some of the Rwandan refugee camps in Zaire (Goma, 1994) which contained
more than 100,000
refugees.
In order to reduce health risks, it is essential that
site planning and organization takes place as early as possible so that
overcrowding is minimized and efficient relief services are provided.
Shelters must be provided as rapidly as possible to protect refugees from
the environment, and infrastructure installed for the necessary health and
nutrition facilities, water supply installations, latrines, etc. All this
must be initiated within the first week of intervention3.
Relief agencies are usually faced with one of two
possible situations: either the camp is already established with a refugee
population that has spontaneously settled on a site prior to the arrival
of relief agencies, or site planning is possible prior to their arrival,
for example, when they are being transferred to a new camp.
Whichever is the case, prompt action must be undertaken
to improve the site and its-facilities; poor organization in the early
stages may lead to a chaotic and potentially irreversible situation in
regard to camp infrastructure, with consequent health risks. For example,
lateral expansion of a site must be accounted for from the beginning in
order to avoid overcrowding if refugee numbers increase.
Two possibilities: a refugee camp or
integration into the host population
There is always a lot of discussion as to whether the
formation of a refugee camp is acceptable, or whether resources would be
better directed to supporting local communities who host refugees. The two
main types of refugee settlement - camp or integration into the local
population - each offer both advantages and disadvantages as laid out
below:
Camp or integration into the local population:

more difficult to reach, leading to difficulties in monitoring health
needs
-
Implementation
of relief programs more complex, requires knowledge of local
situation
-
Risks
destabilizing the local community, risk of tensions between local
community and
refugees
Health agencies are generally not involved in deciding
between the two options. Every refugee situation is specific to
itself. The main factors
influencing the way in which they eventually settle are the number of
refugees, the capacity for the local community to absorb them, the ethnic
and cultural links between the refugee and local communities and the
political and military situation. In practice, the predominant factor is
the relationship between refugees and the local population.
It should, however, be pointed out that relief programs,
particularly food aid may well play a role in attracting refugees into a
camp situation even when integration would probably be a better option for
them.
It is camp situations that are dealt with more
specifically here, because camp populations are exposed to greater health
risks. However, most of the principles described below may also be applied
to open
situations.
Site planning
Site planning must ensure the most rational organization
of space, shelters and the facilities required for the provision of
essential goods and services. This requires supervision by experts (e.g.
in sanitation, geology, construction, etc.) which must be integrated into
the planning of other sectors, especially water and sanitation. It is
therefore essential that there is coordination from the beginning between
all the agencies involved and between the different sectors of activity,
especially in an emergency situation when time is generally in short
supply.
Site planning in refugee situations is normally the
responsibility of UNHCR (or an agency delegated by UNHCR). As UNHCR is
usually not present where there is an internally displaced settlement,
another agency will have to take charge. Although health agencies will not
always be involved in organizing a site, they should nevertheless make
sure that this is undertaken correctly because of its direct influence on
the subsequent health situation; it is therefore necessary to have an
understanding of the basic principles of site planning.
As stated above, the possibilities in regard to site
planning depend largely on which of the two refugee situations described
will be encountered.
1.
In
most cases refugees have already settled on a site and planners may well
be faced with chaotic conditions. The immediate priority must be to
improve or reorganize the existing site, and in rare instances it may even
be advisable to move the refugee population to another site (see
below).
2.
The
ideal but far less frequently encountered situation is that where site
planning can be carried out before the arrival of refugees on a new site.
The most appropriate site layout may then be worked out in advance and in
accordance with
guidelines.
In both situations, the following principles must be
respected as far as possible.
-
Sufficient
space must be provided for everybody: space for every family to settle
with the provision of amenities (water and latrines) and other services,
and access to every sector. High density camps should be avoided because
they present a higher risk for disease transmission, fire and security
problems2.
-
Short-term
site planning should be avoided, as so-called temporary camps may well
have to remain much longer than expected (e.g. some Palestinian refugee
camps have been in existence since 1947) 2. This means that
consideration must be given to the possibilities for expansion should the
population increase1.
-
A
few small camps (ideally circa 10,000 people) are preferable to one large
camp because they are easier to manage and because they favor a return to
self-sufficiency2.
Unfortunately, this is rarely possible when there is a massive
influx of refugees (e.g. the refugee movements in Rwanda and Burundi,
1993-94).
-
Refugees
should be involved and consulted. Their social organization and their
opinions should be taken into account wherever possible.
-
Local
resources (human and material) and local standards should be employed
whenever feasible. Seasonal changes (e.g. the rainy season) must also be
taken into
consideration.
SITE
SELECTION
The ideal site, responding to all requirements,
is rarely available. The choice is generally limited, as the most
appropriate areas will already be inhabited by local communities or given
over to farming. In any case, relief agencies are seldom on the spot to
select a site before refugees arrive.
However, there are certain criteria in regard to site
selection which must still be taken into accountl,9.
-
Security
and protection: the settlement must be in a safe area (e.g. free of
mines), at a reasonable distance from the border, and from any war
zones.
-
Water:
water must be available either on the site or close
by.
-
Space:
the area must be large enough to ensure 30m2 per person (see
Table 5.2).
-
Accessibility:
access to the site must be possible during all the seasons (e.g. for
trucks).
-
Environmental health risks: the proximity of vector
breeding sites transmitting killer diseases should be avoided as far as
possible (e.g. tsetse fly for trypanosomiasis). Where such areas cannot be
avoided, they must be treated.
-
Local
population: every effort should be made to avoid tensions arising between
local and refugee communities; for instance, legal and traditional land
rights must be respected.
-
It
is important that the terrain should slope in order to provide natural
drainage for rainwater off the
site4.
Energy sources should also be considered when selecting
a site, particularly as deforestation resulting from using wood for
cooking fuel entails politico-ecological problems.
SITE ORGANIZATION
Once the site has been secured, the planning and
location of the required infrastructure must be worked out. A map should
be used and the road network drawn onto it. The area should then be
divided into sections and locations decided for the different facilities.
Good access by road to every section and each installation is essential
for the transport of staff and materials (e.g. food and drugs) in order to
ensure the different services are able to function.
Several factors should be taken into account in
deciding the spatial organization of facilities and shelters (location and
layout):
-
space
required per person and for each installation
-
accessibility
of services
-
minimum
distance required between facilities and shelters (see table
5.2)
-
cultural
habits and social organization of the refugee population (clans and
extended families)
-
ethnic
and security factors, relationships among different sections/ members of
the community,
etc.
Cultural
and social traditions are a determining factor in ensuring refugee
acceptance of the infrastructure and services provided, particularly in
regard to housing, sanitation, burial places, etc. However, as the layout that might
be preferred by the refugees is not always the one that would allow the
most efficient delivery of aid, site planning generally requires
compromise solutions that take into account the different points of
view2.

ESSENTIAL INSTALLATIONS
Essential installations are described in Table 5.3. Some
are likely to be centralized:
-
reception
center
-
health
center
-
hospital
-
meeting
place for home-visitors,
etc.
Other facilities, such as health posts, latrines,
washing areas, etc., should be decentralized. Care must be taken to ensure
that there is sufficient space for such decentralized services in all the
camp sub-divisions.

sites

-

community facilities: market, schools, cemetery, meeting places,
etc. |
The location of health
facilities must be carefully determined.
-
The
central health facility should be located in a safe and accessible place,
preferably on the periphery of the site in order to avoid overcrowding and
allow for future expansion. The space required depends on the type and
desired capacity of the medical services to be
provided.
-
The
hospital, if one is necessary, is usually an expansion of the in-patient
service of the central facility. The criteria are thus similar but more
space is required (in line with the number of beds). It is particularly
important to plan space for water and sanitation facilities, as well as
room for eventual expansion (e.g. outbreaks of
disease).
-
The
peripheral health facilities should be centrally located within the areas
they are to serve so as to ensure easy access. The number required depends
mainly on the size of the population (e.g. 1 health post per 3,000-5,000
refugees).
-
A
site for a cholera camp must be identified in advance, separate from other
health facilities. It must be large enough to ensure sufficient capacity
for potential needs and be provided with adequate water and sanitation
facilities6.
THE LAYOUT OF SHELTERS
The way shelters are grouped has an important influence
on the re-establishment of social life, on the use of latrines and
water-points, and on security.
In general, the site should be divided into
smaller units for management purposes. For example, it could be divided
into sectors of 5,000 and sections of 1,000 people. However, the formation
of such units must take into account the existence of any groups within
the population which may be mutually hostile,
Two main ways of grouping shelters are
described:
1.
The
preferred method is to organize the site into basic community units,
constituted by a number of shelters and community facilities (latrines,
water-points and washing areas) 1,3. These basic units should
correspond in design as closely as possible to that with which the
refugees are most familiar. Examples for designing such community units
are available in several reference books
2,4,9.
2.
Laying
out shelters in lines and rows is another possibility, but is usually not
recommended because this deprives families of personal space, and
increases the distances to latrines and water-points. On the other hand,
such a layout can be implemented quickly and is often preferred when there
is a sudden and massive influx of refugees to cope
with.
Since in most cases the population will have settled on
a site before any site planning can be carried out, solutions will have to
be sought for improving the situation.
-
Usually,
the site may be improved without moving all the shelters. A better
organization of facilities, improving access to all sections of the camp,
and carefully planning sections for new arrivals will decrease health
risks and improve camp management,
-
A
thorough reorganization of the site (and most shelters) may sometimes be
necessary, although radical change is usually not advised. Such
reorganization should be considered when there is a real threat to refugee
health from overcrowding or a danger of fire, etc. For example, it was
decided to move and reorganize all shelters in the Rwandan camps for
refugees from Burundi in 1993, in order to counter the high fire risk and
to facilitate the management of relief
assistance.
-
Critical
problems, such as a lack of water in the area, insecurity or potential
danger resulting from the camp's proximity to the border, may present
major obstacles to the camp remaining where it is. A move to a new site
could then be considered, but the operational problems involved in a move
and the social and psychological consequences for the population must be
carefully weighed up in advance,
Shelter
provision
The objectives of providing shelters are: protection
against the elements and against vectors, provision of sufficient housing
space for families, and restoring a sense of privacy and security.
Shelters are required in every refugee emergency; but the type and design
of shelter, who constructs it and how long it should last will vary in
every
situation2.
However, some general principles may be
concluded2:
- Shelters that have already been built by
refugees or buildings occupied by them (e.g. schools) must be assessed. It
is important that consideration is given to the amount of space available
for each person, to ventilation (e.g. risk of respiratory infection) and
for protection against rain, as these factors may entail significant
health risks.
- Wherever possible, refugees should construct their own
shelters and should receive material (including appropriate tools) and
technical support to assist them in doing
so.
- It is best to use suitable local materials where
available. Special emergency shelters (e.g. tents) and pre-fabricated
units have not yet proven practical because of their high cost and the
problems of transporting them. It is also difficult to persuade refugees
to accept something which is not within their cultural traditions.
However, some types of prefabricated shelter are still being tested and
may be suitable for use in the first weeks of an emergency.
- A minimum sheltering space of 3.5m2 per
person is recommended in an emergency. However, different cultures have
different needs. - Single-family shelters are preferable (unless
multi-family units are traditional).
WHEN
REFUGEES FIRST
ARRIVE
The provision of shelter is a high priority. Immediate action should be taken
to assess the arrangements already made and provide material for temporary
shelters2.
There are several common solutions for temporary
shelters:
-
Shelters
built by the refugees themselves, with material found locally or
distributed by agencies, are the most common
solution.
-
Tents
may be useful when local material is not available and as very short term
accommodation, but they are expensive and do not last
long.
-
Plastic
sheeting may be used for constructing temporary shelters or to protect
them. Methods for setting up plastic temporary shelters are described in
guidelines5.
-
Local
public buildings, such as schools, may provide shelter initially but are
not usually suitable for large numbers. They are a very temporary
solution.
THE POST-EMERGENCY PHASE
Temporary shelters should no longer be used after the
emergency stage has passed; an early start must be made to constructing
shelters made of more permanent material.
However, it must be acknowledged that there are certain
constraints involved in such shelter construction programs10.
-
Any
shelter building or rehabilitation program takes time.
-
Such
programs are costly (although they may produce savings in other sectors).
-
As
there is a vast range of options for building shelters and a wide range of
criteria have to be taken into account, such programs are complex to
manage. This is a specialized
job and requires
expertise.
This can often become a highly political issue with
local authorities obstructing the building of (semi-) permanent housing
when they want to prevent refugees settling for a long period of time,
Longer-term housing should be similar to that with which refugees are
already familiar, but should also reflect local
conditions2. The
use of local material is preferable, but its availability may be
problematic (e.g. degradation of the environment through deforestation).
In countries such as Afghanistan or the countries of
Eastern Europe, where very low temperatures may be experienced in winter,
shelter provision is essential for protection against the cold. Although a
few solutions have been proposed (e.g. winter tents and the provision of
heaters), this is a particularly difficult problem to deal with in an
emergency
situation.
Once time allows, traditional housing may be built, if
the materials are available, and there are sufficient financial resources.
Principal
recommendations regarding shelter and site planning
-
Site
planning and improvement should take place as early as possible in
order to minimize overcrowding and make it possible to organize
efficient relief services.
-
A
site should be selected with a view to security, access to water,
the provision of adequate space, environmental health risks, and the
local population.
-
Site planning must ensure the most rational
organization of the available space in regard to shelters and the
necessary facilities and installations. Where refugees have already
settled on a site before any planning could be envisaged, it is not
usually advisable to institute radical changes, but improvements and
reorganization should be carried out.
-
Small
sites are preferred. The cultural and social patterns should be
taken into account.
-
The
provision of material for temporary shelters is a high priority when
refugees first arrive.
These should preferably be single-family shelters,
constructed out of local material (when available) by the refugees
themselves. |
