Climate-Resilient Rice Variety Adoption in Flood-Prone Terai Districts

Level: MasterDifficulty: Intermediate

1. Introduction & Problem Statement

Overview: Study evaluating farmer uptake of drought/flood-tolerant rice cultivars.

Background Context (Nepal): Climate change amplifies flood and drought risks in Nepal's Terai rice bowl. Stress-tolerant rice varieties (STRVs) such as Sub1 flood-tolerant (Swarna-Sub1) and Sukha-drought tolerant varieties protect farmer yields.

2. Research Objectives

›Measure adoption rates and spatial diffusion of Climate-Resilient Rice Varieties (Swarna-Sub1, Ciherang-Sub1, Sukha series) in Jhapa and Kailali districts
›Identify socioeconomic determinants (farm size, seed access, extension contact, risk perception) driving STRV adoption
›Evaluate yield resilience and economic loss reduction under actual submergence / drought weather events
›Assess formal and informal seed supply chain bottlenecks restricting STRV seed availability at agro-vets
›Provide climate-smart agriculture policy recommendations for National Seed Board Nepal

3. Proposed Methodology

Field survey covering 200 rice farming households in flood-vulnerable river basins of Jhapa and Kailali
Multi-stage stratified random sampling across affected and non-affected farming clusters
Probit / Tobit econometric regression modeling in STATA / SPSS predicting adoption intensity
Focus Group Discussions (FGDs) with local seed producer co-operatives and district Agriculture Knowledge Centers (AKC)
Cost-benefit margin analysis comparing local traditional cultivars vs Sub1 varieties during flood years

$ Worked Example / Sample Scenario

Sample Scenario: Surveying 200 farmers in Jhapa during a 10-day flash flood event shows that Swarna-Sub1 rice survived complete flash submergence with an 82% survival rate, producing 3.8 tons/ha, while non-tolerant varieties suffered 90% crop loss.

7. Frequently Asked Questions (FAQs)

Q: How does Sub1 technology allow rice to survive flooding?

The SUB1A gene suppresses stem elongation during complete submergence, conserving carbohydrate reserves so the plant regenerates when floodwaters recede after up to 14 days.

Q: What regression model evaluates adoption decisions?

A Probit or Logit model estimates binary adoption (1 = Adopted STRV, 0 = Non-Adopted), while a Tobit model evaluates proportion of land area allocated.

Q: Where can I get NARC released rice variety manuals?

NARC National Rice Research Program (NRRP Hardinath) publishes official seed characteristics and release catalogs.

Q: What is the average rice yield in Nepal?

Nepal's average national paddy productivity is approximately 3.5–3.8 metric tons per hectare.
