The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
This document contains the presentation by A.P.Dimri on "Wintertime Climatic Analysis over the Western Himalayas", presented at National Climate Research Conference, IIT Delhi, March 5-6, 2010. The eastward moving synoptic weather systems, Western Disturbances (WDs), are the most dominant source of precipitation over the western Himalayas. Topographic variability and landuse …
This paper presents a method for deriving the snowline altitude using a combined analysis of terrain elevation and multispectral Advanced Wide Field Sensor (AWiFS) data from the RESOURCESAT-1 satellite, launched by India on 17 October 2003. AWiFS is a unique instrument capable of acquiring imagery of the world repeatedly every …
The antagonistic potential of seventeen fungal isolates (15 Trichoderma harzianum and 2 Fusarium solani isolates) indigenous to the western Himalayan region of India, was evaluated in vitro and in glasshouse against two important stages (sclerotia and mycelium) in the infection cycle of three plant pathogens (Rhizoctonia solani, Sclerotina sclerotiorum and …
New Delhi: With the last spell of fog on January 27 and 28, this month is now officially the foggiest since the 1960s, having clocked a total of 172 hours of below 200 m visibility. The good news is that the Met department does not foresee too many dense fog …
The dynamics of plant bioresources including agriculture is different in the hills from those in the plains. The agriculture and forestry are the two major land use types and play an important role in providing food and livelihood security. The structure of vegetation for trees and shrubs layer was moderately …
There could be some reason for environmentalists to cheer. This year has seen a significant increase in snowfall in the upper region of Western Himalayas, the primary source of river water for northern India, vis-
Shimla: With an early departure of migratory birds from the Pong Dam and untimely blooming of rhododendron flowers in February acting as alarm signals, scientists and environmentalists today stressed the need for incorporating climate impact and vulnerability into forestry programmes without any further delay.
This issue is the first in the series of WII ENVIS Bulletin that deals with specialized habitats and threatened species covering various Biogeographic Zones of the country. India harbours nearly 45,000 species of plants, about 11% of the world
The documentation of forest wealth in the Himalayas is of great importance because biotic pressure on them. The applied system of management and conservation of forests is of immediate concern for the present and future generation. Such study is useful to know the type of plant community development through succession …
Fundamental to the onset of the Indian Summer Monsoon is the land-sea thermal gradient from the Indian Ocean to the Himalayas-Tibetan Plateau (HTP). The timing of the onset is strongly controlled by the meridional tropospheric temperature gradient due to the rapid pre-monsoon heating of the HTP compared to the relatively …
The changing global scenario and the amendment of national legislations on ownership over biological resources and intellectual property rights over the indigenous knowledge evolved by the local communities for the useful exploitation of these resources, demands that agricultural biodiversity and indigenous knowledge rich countries like India identify the agricultural heritage …
Biodiversity characterisation at landscape level has been carried out using Indian remote sensing satellite data in Western himalayas of India. This study presents the results of the project undertaken to build national database on biodiversity at landscape level.
This study describes time series analysis of snow-melt, radiation data and energy balance for a seasonal snow cover at Dhundi field station of SASE, which lies in Pir Panjal range of the N
The role of socio-cultural values in biodiversity conservation is an integral part of the people living in Uttarakhand, Central Himalaya, India. Due to a variety of reasons the area under traditional crops is declining very fast in the region but undoubtedly many of the crop varieties are still conserved in …
The results of trend analyses of the discharge data of four rivers in northwestern Himalaya, namely Beas, Chenab, Ravi and Satluj, are presented here and the impact of climate change in the last century is discussed. In the case of Satluj river, studies indicate an episodic variation in discharge in …
The vegetation of India evolved in time and space due to geomorphologic changes and the interactions of climate and biotic changes. There is a close linkage between climate and biota. Jul-Dec 2007
The contemporary trend of global warming is aptly highlighted in the IPCC report 2007. There is a strong consensus amongst scientists and planners today that the earth's climate is entering a warm episode, nudged primarily by human activities of fossil fuel burning and land use changes that inject steadily increasing …
Glaciers are the coolers of the planet earth and the lifeline of many of the world's major rivers. The interaction between glaciers and climate represents a particularly sensitive approach. 2006
