Modified stove assembled with heat-exchanger and water tank (Daler Domullodzhanov)
In Tajikistan, forest cover has been reduced to 3% of the land area: it must not be allowed to decrease further. Forest destruction contributes to natural disasters that affect the environment and agricultural land, as well as damage houses and endanger lives. Examples are:
- floods: such as in 2012 that caused huge losses for rural households and infrastructure;
- landslides caused by soil erosion;
- fertile soil washed away, and water infiltration and holding capacity of the soil reduced;
- fewer reliable water sources and reduced flows with poorer quality;
- microclimatic changes and reduced rainfall becomes less.
To reduce pressure on the existing forest area of the Muminobod district and also to decrease the use of dried cow dung cakes for fuel that are better used as fertilizer, in the framework of the energy efficiency project of Caritas Switzerland a modified metallic stove has been developed that uses much less firewood than the stoves currently in use. This energy-efficient stove was developed in close cooperation with local blacksmiths and active women field promoters in pilot houses. There are multiple advantages including a 30% saving of energy for cooking, simultaneous heating of water and warming the living space. Furthermore, the stoves are cheaper, the work of women is reduced and there is no smoke inside the room. Further advantages can be obtained by using accessories such as a heat exchanger, and a water boiler/water radiator to make the stove multi-functional.
The stoves are 70 cm in length, 32 cm wide, and 20 cm in height with 2 burners of different diameters.
Advice on installation and best use of stoves and accessories include removing ash before lighting; cleaning the chimney; regulating the flame by use of the inlet draft controller; ensuring regular air exchange in the room; installing the heat exchanger at a minimum 40 cm height from the stove and cleaning regularly. To ensure proper circulation of the water in the system water tank should be lifted 15—20 cm from the ground level.
Moreover, other international organisations have provided technical and financial support to farmers to establish agroforestry plots and orchards, to rehabilitate degraded forest areas, and to set up nurseries to produce planting materials to sustain the afforestation process. The fruit orchards have multiple benefits: they yield fruits, produce firewood, anchor topsoils, prevent soil erosion, maintain water balance, protect the environment and absorb greenhouse gasses.
