Purpose This paper aims to gain insight on the perception and role of the local government officials on climate change and resilience in Uttarakhand, India. Uttarakhand, being a sensitive mountainous region in India, faces the brunt of frequent climate-related disasters and their severe impacts. Therefore, it is crucial to understand how authorities perceive the issue of climate-related disasters and their level of commitment toward mitigation and adaptation programs. Design/methodology/approach The literature review method was used for a holistic understanding of the impact of climate change and consequential disasters. A questionnaire survey method, comprising open- and closed-ended questions, was also used on officials of different departments. Findings Among the noteworthy findings of the study include the understanding of the perceptions of authorities and their role in decision-making on mitigating impacts of climate change-related disasters, their support or lack of it, for measures toward capacity building and spreading awareness of the intervention programs by the government. The study analyzes the perception of decision-making officials at state and district levels and infers that the variation on opinions may be attributable to multiple factors, including their past experiences of dealing with disasters. Originality/value This study offers insights into the role of perception of local government officials concerning climate change-related disasters and alleviation of their consequences through related programs. The findings have the unique potential to serve as a guide for the government at state and district levels to assess various aspects of different disaster mitigation measures based on sectors and departments.

Plant lifespan has important evolutionary, physiological, and ecological implications related to population persistence, community stability, and resilience to ongoing environmental change impacts. Although biologists have long puzzled over the extraordinary variation in plant lifespan and its causes, our understanding of interspecific variability in plant lifespan and the key internal and external factors influencing longevity remains limited. Here, we demonstrate the concurrent impacts of environmental, morphological, physiological, and anatomical constraints on interspecific variation in longevity among >300 vascular dicot plant species naturally occurring at an elevation gradient (2800-6150 m) in the western Himalayas. First, we show that plant longevity is largely related to species’ habitat preferences. Ecologically stressful habitats such as alpine and subnival host long-lived species, while productive ruderal and wetland habitats contain a higher proportion of short-lived species. Second, longevity is influenced by growth form. Small-statured cushion plants with compact canopies and deep roots, most found on cold and infertile alpine and subnival soils, had a higher chance of achieving longevity. Third, plant traits reflecting plant adaptations to stress and disturbance modulate interspecific differences in plant longevity. Importantly, we show that longevity and growth are negatively correlated. Slow-growing plants are those that have a higher chance of reaching a maximum age. Finally, changes in plant carbon, nitrogen, and phosphorus content in root and leaf tissue were significantly associated with variations in longevity. We discuss the link between the longevity and productivity and stability of studied Himalayan ecosystems and the intrinsic growth dynamics and physiological constraints under increasing environmental pressure.
