Crop Productivity and Sustainable Agricultural Systems in Snow-Receiving Hazardous Himachal Mountains: A Review

Abstract

The snow-receiving regions of Himachal Pradesh — Lahaul-Spiti, Kinnaur, upper Kullu and parts of Chamba, lying broadly above 2,000 m amsl — sustain agriculture under severe constraints: short growing seasons, snowmelt-dependent irrigation, fragmented holdings, steep erodible slopes and recurrent natural hazards. This paper reviews published literature, government statistical reports, and institutional assessments for the period 2000–2025 to assess crop types, productivity, investment cum developmental schemes, natural resources, hazards, and sustainability constraints having accessible intermittent and scattered evidence in the concerned and related regions. Reported snow season warming of about 1.2°C during 1982–2007 at Solang (2,500 m), nearly 50 percent reduction in seasonal snowfall, and earlier snowmelt have disrupted the kuhl-fed irrigation on which the region depends; only about 12 percent of Kullu's net sown area is irrigated. Yields remain well below national and international benchmarks — wheat about 1.85 t ha−1 (State average, 2023), barley 1.5–2 t ha−1, seed potato 20–30 t ha−1 — while apple productivity has been declining at about 0.183 t ha−1 per year. Public investment is substantial and rising, yet reported scheme progress for 2010–2015 shows near-uniform annual increments that warrant independent verification, and no published study relates investment to measured productivity gain in snow-receiving tracts. The review concludes that drought-resistant cum cold-tolerant and high-value crops, micro-irrigation and kuhl restoration, soil, snow and water conservation, afforestation and hazard-sensitive planning together offer a workable adaptation pathway, but that altitude-stratified monitoring, controlled crop trials and independent scheme evaluation are prerequisites for sound policy. Limitations of the underlying data are stated explicitly throughout.
