Impact of Climate Change and Adaptation Measures on Transhumance Herding System in Gatlang, Rasuwa

Abstract

Climate change impact is global and Nepal is no exception, posing vulnerability for different communities and regions. Transhumance herding is the culture and identity of indigenous settlement in Himalayan region where herders follow vertical transhumance herding as a part of subsistence mixed agriculture system for their livelihood. It differs from nomadism in terms of its periodicity, regularity, and mobility. This study confers the impacts of climate change and adaptation on transhumance herders in Gatlang of Rasuwa District. Focus Group Discussion, Key Informant Interview, and Questionnaire survey were carried out covering herder’s perception toward climatic variability, changes in the biophysical indicator, its impact and adaptation strategies. Data were analyzed using descriptive statistics, weighted mean, and Index of Usefulness of Practice for Adaptation (IUPA) tools. This study showed increase in mean average temperature (0.0202°C), increase in monsoon precipitation (2.1 mm) and decrease in winter precipitation (0.5 mm). Seasonal movement of livestock was mainly guided for adjusting temperature. The observed changes in biophysical indicator were diverse with shrinking grazing lands as most agreed statements followed by low crop productivity and faster melting of snow in rangeland. Herders perceived different adaptation strategies where reserving some grazing areas scored highest IUPA ranking followed by seasonal movement, storage of grass/hay, and so on. Though transhumance itself is one of the adaptation strategy against climate change people were not aware about changing monsoon precipitation and following same seasonal calendar as before which have affected livestock. These observations suggested that herders were unaware of the underlying cause and its impacts on the system which needed to be monitored scientifically.
