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 …
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-
Climate and its variability have been and continues to be the principal source of exceptional fluctuations which wreaked havoc on forests. In Chamba, up to an elevation of 1,800 m chir pine (Pinus roxburghii Sargent) is the main naturally occurring coniferous tree in forests. Plantations of Chir pine are also …
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.
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 …
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 …
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
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 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 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 …
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
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 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 …
Intense rainfall often leads to floods and landslides in the Himalayan region even with rainfall amounts that are considered comparatively moderate over the plains; for example, ‘cloudbursts’, which are devastating convective phenomena producing sudden high-intensity rainfall (∼10 cm per hour) over a small area. Early prediction and warning of such …
Two cases of intense western disturbances which affected the northwest India have been investigated using the India Meteorological Department’s operational limited area analysis and forecast system. The model results are compared with the synoptic observations, which have been enriched by additional stations installed under the national project ‘Parwat’. The analysis …
model town: Aizawl, the capital of Mizoram, is likely to be the northeast region's first planned township. The move to prepare the city's master plan was actually triggered by fears about an impending earthquake and a rapidly expanding hill town that is already bursting at its seams. In stark contrast …
