Although it's major development components have
been completed, the success of this entire programme depends on
the continued flow of adequate quantity and quality of water into
the reservoirs and sustainable management of natural resources on
the whole Mahaweli Basin.
With these concerns in mind, Mahaweli Authority
of Sri Lanka (MASL) established the Upper Mahaweli Environment and
Forest Conservation Division (EFCD).
Land Use
Planning
Land use planning is a decision support activity,
which provides information and guidelines on sustainable land resources
management. This section works in the field of land use mapping,
provision of technical guidance on land resource assessment, environmental
management activities, land use planning and watershed management.
Sedimentation
Monitoring Programme
The main objective of the section is to implement monitoring programs
to obtain information on river sediment transport and to quantify
the effects on sub watersheds of Upper Mahaweli watershed. Apart
from that our section takes care of maintenance and construction
activities of the division.
Hydrological performance monitoring is important
to identify the situation of the watershed. Sediment and water yields
are two indicators monitored under this programme. As the resources
are scarce, the division decided to move along the selected sub-watersheds
and sediment monitoring is done only for a short period of time.
This will enable us to calibrate it with the water flow. Subsequently,
water flow monitoring is done automatically. During the calibration
period, all possible flow patterns (peaks and low flows) are covered.
We are aware of the fact that this kind of monitoring will help
only to detect non-point, and continuous sources of sediments. This
helps us to identify our long-term conservation programme. In any
case, point sources are incidental and natural recovery is very
speedy. Damage control from such sources needs more of regulatory
measures rather than technological.
Natural
Resource Conservation
§ This section is responsible for Planning
& implementation of natural resources conservation programmes
related to watershed management in the Upper Mahaweli Catchment
Area (UMCA)
§ The implementation of natural resources management
activities are carried out through Local government institutions
and other line agencies in the UMCA
Environmental
Education
The principle mode of operation for the Environment
education is based on participation. Following approaches and strategies
are being used various means of mass media/ communication; newsletters,
radio programmes, exhibitions, video films, slide shows, competitions,
leaflets, posters, booklets, excursions, training programmes, projects,
seminars, workshops, meeting etc. Communication support materials
are developed and collated by the section itself.
The target groups range from School children to
line agency staff, the local political leaders, under graduate youths,
farmers, extension workers, NGO staff etc.
Training
Centres
EFCD has three training centers: – Polgolla, Doragala and
Pallekelle. These training centres are equipped with audio-visual
facilities and other training equipments. Pallekelle center has
residential facilities for 20 participants. Demonstrations are established
on soil and water conservation, medicinal plants, watershed management
and the biodiversity aspects.
Mahaweli
Pavithra Ganga (CLEAN RIVER) Prpgramme
The Mahaweli-Ganga has a catchment of 10,400 kms,
which is 1/6th of total land area of Sri Lanka. The Mahaweli-Ganga
has been dammed at 5 places and constructed large water reservoirs
for irrigation & hydropower generation. The Polgolla reservoir/
barrage is the major diversion point for entire Mahaweli development
network.Polgolla reservoir is being polluted due to the garbage
/ industrial waste dumping in to the Mahaweli river and major tributaries.
It is also recorded that, quality of the water is being drastically
deteriorated.
There is also a increasing trend to pollute Kandy
lake. Deforestation of the sensitive catchment areas, vegetation
burning, soil erosion, encroachment, improper and illegal house
construction, illegal sand mining and improper garbage/sewage disposal
are the major reasons for the above situation.
This situation negatively affect the beauty of the
world heritage Kandy city and the objective of the Mahaweli development
programme. The “Mahaweli Clean River (Pavithra Ganga) programme”
is an initial intervention of future Mahaweli River Basin Management
Agency.
“Mahaweli Pavithra Ganga Programme”
is a concept in which the theme is to keep Mahaweli River &
reservoirs clean in a sustainable manner. This programme is implemented
based on local government institutional areas, which are, located
either sides of the Mahaweli river from Hatton to Victoria dam in
the Upper Mahaweli Catchment. The extent of Upper Mahaweli Catchment
is 3118 km2. The Upper Mahaweli is the upper part of the Mahaweli
River above the Rantembe dam. This Upper Mahaweli catchment area
can be considered as the heart of the country.
