Spatial variability of climate and land use pattern in Dabka watershed.
32ºC in 1985-1990. The average minimum annual temperature was 7ºC in
1985-1990, whereas it had gone down to 4ºC by 2005-2010. The climate data
indicate increasing trends of extreme cold and hot weather in the months of
January and May. Consequently the average annual temperature increased
about 2ºC in 1985-2010 at a rate of 0.10ºC a

.
Rainfall:
In the 2005-2010 period, average annual rainfall within the
watershed varied between 1623 mm at Maniya (on an environmentally
stressed barren hill slope) and 2187 mm at Ghughu (on dense forest hill
slope), while it was 1969 mm at Bausi (on agricultural land), and 2086 mm
at Jalna (on fairly dense forest/shrub land). Throughout the watershed the
