- The annual phosphorus load to
Lake Ohrid is estimated at 240 t/y, 154 of which is in dissolved form,
readly available to the algae.
- More than 30% of the dissolved phosphorus
originates from the rivers and the springs, that is, form non-point
sources of pollution.
|
|

|
- The pollutions loads from the
non-point are often calculated on the basis of a set of
estimations/approximations, very often originating from different
regions or countries having different agricultural traditions and
practices.
- Having a clear picture of the
pollution loads and sources of pollution is substantial for the
identification and setting out of the management priorities.
|
|

|
- Because a limited amount of
funding is available, efforts to reduce phosphorus should focus on
sub-basins most affected by phosphorus. The regional watershed
associations of citizens can play a crucial role since they are familiar
with non-point pollution sources within the sub-basins. Therefore, it
rests heavily on public education and creating an active public
participation and public support.

- The watershed approach at
whole and the control of the non-point sources of pollution in
particular, relay very much on the involvement of and contribution from
the stakeholders and the public in general.
- The ongoing educational and
demonstration programs coincide with several important actions in the
field of the agriculture proposed by the Lake Ohrid Watershed Committee

- Lake Ohrid Conservation
Project provide a framework for coordination and cooperation among key
interests in the development and implementation of the management plan
for the Lake Ohrid Watershed. In this respect, the Agency for
Development and Promotion of the Agriculture of Republic of Macedonia
plays a very important role. This is especially true in tackling down
the non-point sources of pollution.
|
|

|
- Very important part of the
implementation strategy is the cooperation with agricultural
associations and individual farmers.
- The best example of
cooperation is the program for monitoring the activities of the
individual farms.
|
|

|
- The Monitoring program consists
of several modules:
- 1)Regular recording of a set of
parameters (monthly incomes and expenses , usage of pesticides ,
fertilizers , other agrochemicals)
- 2) Collecting information on
different practices (storage and application practices of the animal
manure , agricultural methods and technology used at the farm )
- 3) Data analysis (indicate the
sources of losses or inefficiency.
- 4) Field visits and
consultations (directly observing the practices applied and eventually
give direct recommendations and guidance )
|

- Educational Programs focus on several area
- Adequate use of agrochemicals,
handling of surplus pesticides and agrochemicals, controlling wash water
from agrochemical application machines; dumping of the packing etc, in
order to protect the surface and ground waters;
- New methods for maximum plant
protection and minimum pollution including:
- a) Solar radiation of the soil, by using
sunbeams and PVC foil
- b) b) Using biological substances. They stimulate
plant’s growing, protect them, they don’t pollute, they are not
toxically for plants
- d) c)Using bacteria in disintegration of surplus pesticides
that remained in the soil.
- d) Analysis of the soil to
find out which chemical element it consist from and their amounts; which
fertilizers and quantity of them are important for correct plant’s
growing.

- In the frame of the Lake Ohrid
Conservation Project pilot projects for establishing manure management
systems for dairy, pig and poultry farms in the Lake Ohrid watershed
will be financed
- The aim is to promote an
integrated land and water management and, ultimately, to reduce the
discharge of nutrients and other agricultural pollutants in Lake Ohrid,
other the surface waters and groundwater and the watershed.
- The pilot manure management
system should consists of manure pad and liquid animal waste storage
tanks and equipment for handling
and spreading of the waste.

- 1 Following a number of filed observations, visits of eligible farms and
calls for Expression of Interest published in national news papers, the
following sites have been selected by the WMCs in the Lake Ohrid
watershed:
- · Two dairy farms (25-45 cows; estimated amount
of manure per month: 1.000 - 2.000 tons) on the Macedonian part of the
watershed;
- · Two pig
farms (100 - 200 pigs) on the Macedonian part of the watershed;
- · One poultry farm - estimated amount of
manure per month: 10.000 tons) on the Macedonian part of the Watershed;
- A number of households having
a small number of animals with variable amounts of manure produced per
month in several villages on the Albanian part of the watershed.
|
|
13
|
- a) design and provide estimated costs for a typical waste
management system at pre-selected farms and at the household level;
- b) propose criteria for selecting/ranking eligible investments and
prepare an indicative investment program; and
- c) prepare construction and equipment specifications for bidding
documents.
