| Abstract: |
Household survey was done with randomly selected 148 respondents from three districts, representing the altitudinal
variation focusing to maize growing areas in inner terai (Chitwan), mid (Kaski), and high (Mustang) hills of Nepal to
explore the farmers’ perception on climatic variabilities and maize production relating to the insect diversity. Data were
collected through purposive random sample survey of households using a stratified-multi stage cluster sampling method.
Findings revealed that majority of farmers were aware of climate change, particularly about the climatic variability and
its impact on maize production, but they posses poor knowledge about appropriate adaptation strategies. The findings also
showed that most of the respondent farmers (68.9%) experienced increased temperature whereas about one-third (35.5%)
also experienced about erratic rainfall pattern. About three-fifth of the respondent farmers felt about the emergence of insect
pests in the last decade, and they relate this fact as the effect of climate change, resulting decreased maize production over the
years. Analysis of the recorded temperature revealed an increment of 0.02-0.07°C/ temperature/year with the increment of
precipitation of 24.6 mm/year between 1980 and 2018, and these facts matches well to the perception of respondent farmers.
Findings also identified the major problems related to the maize production as pest severity, lack of labour, unavailability
of improved seed, poor extension service, and frequently occurrence of drought. Likewise, pest attack was also revealed as
an important cause of decreased maize production. About two-fifth (44%) respondent farmers considered stem borer as the
most prevalent pest in all ecological domains, causing significant damage to maize. Majority of the farmers followed only
cultural practices to manage pests whereas their poor knowledge on insect and disease management was the major challenge
to increase maize productivity that needs serious consideration for a better policy formulation and planning |
