| Abstract: |
This study was conducted in seven vegetable seed production pocket districts representing
high hills, mid hills and terai region of Nepal. This study was based on the primary
information collected using semi-structured questionnaires, focus group discussions and
key informants survey. Meteorological data of last 10 years from different metrological
stations on or nearby the production pockets were collected and analyzed. The pattern of
rainfall shows a slightly increasing trend in the mountainous areas receiving higher
amount of annual precipitation. Amount of total precipitation in mid hills was found
decreasing continuously with a slight increase in the year 2007. The pre-monsoon and
winter rainfall was also in decreasing trend in terai whereas, rainfall pattern shows
increasing trend in high hills which shows terai areas more vulnerable due to erratic
rainfall pattern whereas high hills might benefit from the increasing rainfall pattern to
some extent. A slightly increasing trend was noted in average annual temperature within
the study area in a decade. The increasing trend of temperature was found higher in high
hills and mid hills as compared to Terai. Furthermore, warming in the winter was higher
as compared to other seasons. Eighty-six percent of respondents in high hills, 72% in mid
hills, 78% in terai responded that they felt increase in temperature as compared to
previous years. Similarly, the increase in winter temperature was felt more than that of
summer experiencing warmer witers than previous years. The high hills received higher
amount of precipitation in the recent years in terms of intensity and duration of monsoon.
Almost all vegetable seed producers in high hill felt increased precipitation whereas trend
of rainfall was in decreasing pattern in mid hills and Terai as experienced by 81% and
60% of the respondents respectively. Twenty percent in Mustang, 12% in mid-hills and
4% in Sarlahi reported that they felt some positive impacts due to climate changes. Fortyone
percent of the respondents in Mustang expressed their view that cultivation of brinjal,
chilly and cucurbits has been done successfully in Mustang these days. The flowering and
ripening of broad leaf mustard, cabbage and carrot has sifted 10-15 days before. Most
negative effects were felt in Sarlahi as responded by 89% of the farmers followed by mid
hills (78%) and Mustang (40%). Sixty-six percent of the respondents in Mustang, 72% in
mid-hills and 86% in Sarlahi felt that the planting time has pre-pond by about 15-20 days.
The shift was found greater in Mustang (25 days) and lower in Sarlahi (13 days).
However, planting time in case of rainy season crop had shifted some days after (22% in
mid-hills and 8% in Sarlahi) generally due to delayed monsoon. |
