Thesis Topic Ideas: Climate Change Impact on Rice Yield in Terai

1. Introduction & Problem Statement

Overview: Agronomic and climate trend analysis measuring how rainfall variability and temperature spikes impact paddy productivity across Terai districts.

Background Context (Nepal): The Terai region produces the majority of Nepal's paddy crop. Unpredictable monsoon patterns, droughts, and flash floods threaten national food security.

2. Research Objectives

• ›Analyze 20-year historical climate data (rainfall, maximum temperature) alongside paddy yield statistics in selected Terai districts
• ›Quantify yield losses caused by delayed monsoons and drought spells
• ›Assess farmer adoption of drought-tolerant rice varieties (Sukha series)
• ›Provide climate-smart agricultural adaptation recommendations

3. Proposed Methodology

1. Collect historical weather data from Department of Hydrology and Meteorology (DHM) and yield data from MoALD
2. Perform multiple regression and time-series trend analysis in SPSS/STATA evaluating climate impact on yield (tons/ha)
3. Field survey of 100 rice farmers in Jhapa/Morang evaluating perceived climate impacts
4. Calculate economic loss per hectare during extreme weather years
5. Draft agronomic recommendations

$ Worked Example / Sample Scenario

Sample Scenario: Econometric regression over 20 years of DHM climate data in Jhapa indicates that a 1°C increase in average monsoon temperature reduces paddy productivity by 0.32 tons/ha.
