“…Pre-monsoon precipitation, however, was negatively correlated with earlywood density but positively correlated with ring width. In contrary, latewood density did not show any coherent relationship with climate (Borgaonkar et al 2001).…”

A large number of tree species, especially of conifers growing in the Himalaya and a few broad-leaved taxa in the peninsular region, have been dendrochronologically analyzed in India. This paper is a review providing information as regards the present status and future prospects of tree-ring research in India. Many trees are recorded to have datable tree rings but only some of them have been used for climate reconstruction and other aspects, e.g., glacial fluctuation or palaeo-seismic dating. In future not only ring width which is widely used so far, but also other tree-ring parameters need to be analyzed for a better understanding of the regional climate and its linkage with other climatic phenomena in a global perspective.

“…the ratio between the weight and volume of a piece of wood) to micrometre precision (Pagotto et al, 2017;Polge, 1970;Schweingruber et al, 1978). The potential of wood density parameters such as MXD for dendroclimatic research using coniferous species was noted in the late 1990s in the Himalaya (Borgaonkar et al, 2001;Hughes, 1992Hughes, , 2001Pant et al, 2000). Both the MXD and MND are strongly influenced by pre-monsoon summer climate.…”

“…For instance, the MXD of C. deodara from the western Himalaya appears to be positively correlated with pre-monsoon temperature ( r = 0.39, p < .01 ) and precipitation ( r = 0.41, p < .01 ) between March and May (Pant et al, 2000). Although the climatic responses vary for different species and from place to place, studies show that compared to MXD, the MND records stronger climate signals in the western Himalaya (Borgaonkar et al, 2001). In the Kashmir valley, Hughes (2001) found that the relationship between MXD and temperature became weaker from the middle of the 20 th century, but no long-term trend was observed.…”

Recent developments in tree-ring research offer great potential for reconstructing past climate changes; determining the frequencies of natural hazards; and assessing the availability of freshwater resources over timescales that extend well into the pre-instrumental period. Here, we review the state of dendrochronological research in the Himalaya and outline future directions for tree-ring-based hydrological reconstructions in a region that has a pressing societal need to understand the causes and consequences of past, present and future changes in the hydrological cycle. We used ‘tree ring’ and ‘Himalaya’ as keywords to identify scholarly articles from the Web of Science that were published between 1994 and 2022. The resulting 173 publications were separated by their spatial coverage into the western, central and eastern Himalaya, as well as their scientific purpose (e.g. reconstructing growth-climate relationships, temperature, precipitation, streamflow, floods, droughts, etc.). Our analysis shows that dendrochronological research in the Himalaya primarily focused on understanding growth-climate relationships using annual tree-ring widths measurements obtained for coniferous species, and their application in climate reconstructions. Reconstructions of hydrological processes such as streamflows, and extremes such as glacial and landslide lake outburst floods, have received less attention. Recent advances in dendrochronology, including blue intensity (BI), quantitative wood anatomy (QWA), and tree-ring stable isotopes (TRSI) should be combined to improve the resolution and accuracy of hydrological reconstructions in all parts of the Himalaya. Such studies may allow us to better understand the effects of climate change and the Himalayan water resources for its lowland surroundings. They may also facilitate decision-making processes for mitigating the impacts of climate change on natural hazards, and for better managing water resources in the region.
