Recognizing the close interrelation between forests and water
Recognizing the close interrelation between forests and water. Concerned that climate change will have severe effects on the frequency, scale and intensity of natural hazards such as floods, debris flow, avalanches, storms, and droughts and will have an impact on forest and water resources and their management. Stressing the role of forests and forest management in protecting water quality, managing water resources for the quantity of all waters, flood alleviation, combating desertification and soil protection as well as the importance of mountain forests in the reduction of land slides, erosion and effects of avalanches. Emphasising that the full economic value of forests has to be adequately recognised and in particular the value of providing ecosystem services

FOREST EUROPE (Ministerial Conference for Protection of Forests in Europe)
On the 5th Ministerial conference of Forest Europe held in Warszawa in 2007, were adopted joint declaration and 2 Ministerial resolutions: The Warsaw Declaration recognizes the role of forests and their sustainable management in climate change mitigation and highlights the need to ensure adaptation of forests and forest management to climate change. Warsaw Resolution 1 (Forests, Wood and Energy) urges the countries and the European Community to enhance the contributions of the forest sector to energy production and mobilization of wood resources. Warsaw Resolution 2 (Forests and Water) called for action to coordinate policies on forests and water, as well as to promote the management of fresh water resources as part of sustainable forest management.

PROJECT Taking in consideration close cooperation with CNVP (a legacy organisation of SNV in the Balkans for forestry and rural development) following the Warszawa resolutions, we prepared a proposal project - 'Study and Analysis of Innovative Financing for Sustainable Forest Management in the Southwest Balkans‘. - 2 pilot case studies: In Albania focus was on Forest –water relations, while in Kosovo on wood biomass energy. CNVP was responsible for overall project management. World Bank – PROFOR financed the project with total duration of 36 months in 2 phases. .

ALBANIA CASE STUDY – PROBLEM
In the late 90’s of the XX century, significant part of the forest in the ULZA reservoir catchment was fully destroyed. It enabled high erosion processes and siltation of the UlZA reservoir. The main use of water from the reservoir is for energy production – Ulza HPP. Lower part of the forest in the reservoir catchment is under competences of the Communes and Communal forest associations. Forest cut is restricted. Citizens from the commune need fuel wood but they can not supply from their region. Beneficiary of cut restriction was State Energy Company of Albania. ( now ULZA HPP is sold) Because is restricted right of communes to use the forest with aim to protect the Ulza Reservoir from siltation, beneficiary should indemnify the Commune . The possible instrument for this is Payment for Ecosystem Service. PES could be calculated based on model for erosion and sedimentation WB and the Government of Albania were in the process of finalization of the expected new ESP (Environmental Services Project). The ESP will among others focus on specific environmental services and pilot for Payment for Environmental Services. The study carried out in frame of this project on watershed management, demonstrated through sound scientific methodologies how payments for environmental services (PES) could benefit rural land owners and private dam operators while improving environmental sustainability. The baseline data generated formed the basis for a local PES scheme.

Study region: Ulza reservoir basin – Mati river
m asl High roughness of the terrain A = 1244 km2 Vl = 240 mil. m3

The Ulza Hydro Power Plant (HPP) is located on Mat River upstream from mouth of Fani River and near the village of Ulza and Burrel town. It is a 64 m high concrete gravity dam with straight axis with impounded volume of 240 mil m3. The reservoir created serves as a head pond for the Mat river cascade. Downstream from Ulza Dam is located Shkopeti dam that is 50 m high concrete gravity dam with impounded volume of 40 mil m3. Ulza dam has been constructed in the period of year 1952 to It is a concrete gravity dam with a straight axis. Water tightness of the dam foundation is achieved by a grout curtain. The maximum height of the dam above foundation is 64.2 m and the crest length is 260 m. The crest elevation is at m asl and the maximum water level in the reservoir is at m asl (full supply level). Minimum foundation level is 67.5 m asl. The dam volume is 0.26 million m3. The following are some basic characteristics of the Mat River: • Annual discharge volume: 3,250 million m³ • Specific discharge: 40.1 l/s/km² • Ratio of wettest month (December) to driest month (August): 10 • One in 10 years high flow: about 25 times the river module • Storage capacity of Ulza reservoir: 240 million m³ (about 15% of annual flow of the Mat River) The average annual inflow into the reservoir is million m3. The reservoir total storage is 240 million m3 and The active storage volume is 124 million m3. Maximum water level is m asl, while Maximum operation water level is little bit less, i.e m asl. Minimum operation water level is 117 m asl.

WHY STILL HIGH EROSION INTENSITY in ULZA reservoir catchment
25
Ulza (Alb) vs Kalimanci (MKD)
Almost the same catchment area 1983 Z = 0,58 G = m3 y 2014 Z = 0.30 G = m3 y 2014 Z = 0,54 G = m3 y
27
Why decrease of sediment yield in the Kalimanci reservoir
Dry period (lower precipitation, lower discharge…) Consolidation >>> “effective sediment” (permanent decrease per years based on measuring) Erosion control works
28
MASS AFFORESTATION
29
CHECK DAMS
30
During the filed visit of the ULZA reservoir catchment hasn’t been noticed any check –dam.
All natural factors are worse then in Kalimanci catchment. BUT Focus on erosion control was on agricultural land where are noticed terraces. Beside it were noticed forest plantations. But should be payed attention on hydraulic structures in the torrential beds too.

Thank you for your attention!
SOIL Erosion "The threat of nuclear weapons and man's ability to destroy the environment are really alarming. And yet there are other almost imperceptible changes – I am thinking of the exhaustion of our natural resources, and especially of soil erosion - and these are perhaps more dangerous still, because once we begin to feel their repercussions it will be too late." (p144 of The Dalai Lama's Little Book of Inner Peace: 2002, Element Books, London) Thank you for your attention!
