More than a fifth of the world's migrating species are at risk of going extinct as a result of climate change and human encroachment, according to this report by the United Nations. Migratory species globally are facing critical challenges, with nearly half in decline and over 20 per cent threatened …
Dinitrogen (N2) fixation is widely recognized as an important process in controlling ecosystem responses to global environmental change, both today and in the past; however, significant discrepancies exist between theory and observations of patterns of N2 fixation across major sectors of the land biosphere. A question remains as to why …

The ad hoc coastal development projects, which have been conceived and proposed in total disregard to environmental concerns, pose a serious threat to marine biodiversity and the livelihoods of 500,000 fishermen, besides putting human life at risk. The Sindh-Balochistan coast is very much vulnerable to cyclones and floods and implementation …
GDP does not calculate the wealth of ecosystems and biodiversity Human well-being is completely dependent on the smooth flow of ecosystem services, such as food, fibres, clean water, healthy soil and carbon capture. They are public goods, but with no market and no prices, and hence are rarely detected by …
Agartala, July 6: The Tripura Home Guards have set up a huge plant nursery during the spare time of the volunteers within a year and also announced to supply the plants to all public authorities for planting in their campus and along the busiest roads of the State in the …
Many evidences have been gathered to depict that climate change is taking place. A changing climate has strong implications for biodiversity changes and impact on the phenology and distribution of species alongwith community composition and ecosystem dynamics. These parameters may be used to find out indicator species to detect the …
The rapid increase in food prices in many countries has led to substantial media attention on agriculture. This publication does not attempt to cover everything there is to know about agricultural ecosystems. Rather, it tries to present well documented facts and figures to better understand the challenges facing the sustainable …
The Agri Horticultural Society of Western India, a non-governmental organisation taking care of the Empress Garden has decided to form a committee to protect the greenery in Pune. The committee will be named as - Harit Pune Sanrakshan Samiti, said Suresh Pingle, secretary of the organisation. "It has been observed …
The nonpartisan Heinz Center this week issued a comprehensive update on the health of U.S. ecosystems--along with a plea for the U.S. government to coordinate and fund future assessments.
Here the authors present results of the first multi-decadal experiment to examine the impacts of chronic, experimental nitrogen addition above ambient atmospheric nitrogen deposition. This total input rate is comparable to terrestrial nitrogen deposition in many industrialized nations. The researchers found that this chronic low-level nitrogen addition rate reduced plant …
The coastal and marine nitrogen cycle occupies a complex, central role within the biogeochemical cycles. Human interventions in the earth system have risen to unprecedented levels, strongly influencing the global nitrogen cycle. The nitrogen cycle in the open ocean compared to coastal ecosystems appears to have remained unharmed, although recent …
Cotton, as a commercial crop has gone through subsistence, ecological, exploitation, crisis and disaster phases of pest management, with insecticides on focus at the later three stages. Restructuring of pest-management strategies during the last few decades under the banner of Integrated Pest Management (IPM) or Insecticide Resistance Management (IRM)continued to …
Sustaining forest health is critical for sustaining livelihoods, conserving biodiversity, producing biomass and protecting watersheds and river valley systems Prof N H Ravindranath Climate change's impact on physical and biological systems is irrefutable. Forests account for nearly a third of the planet's land surface and over a billion people depend …
Not just humans, climate change will also impact the microscopic world of bacteria, fungi and other microbial populations that support life on earth. "Microbes perform a number of critical functions for ecosystems... we are only starting to understand the impact that global climate change is having on them," said Kathleen …
The hospitality industry is finding that "going green" saves money and prevents pollution. As a step in this direction, a few hotels in the Capital have introduced eco-friendly measures like using recycled paper and herbal soaps, planting trees around the property, non-toxic herbal pest control, noise filters... One of the …
Today, climate change is the most potentially dangerous environmental threat facing human beings and other life forms. The impact of climate change will be particularly severe in the tropical areas such as South Asia. South Asian countries already face tremendous pressure due to increased population growth, urbanization, industrialization and other …
This technical paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a …
Mangrove forests are highly productive but globally threatened coastal ecosystems, whose role in the carbon budget of the coastal zone has long been debated. Here we provide a comprehensive synthesis of the available data on carbon fluxes in mangrove ecosystems. Original Source
The rise in concentrations of carbon dioxide in the atmosphere from human activities is influencing climate patterns and vegetation across the United States and will significantly disrupt water supplies, agriculture, forestry and ecosystems for decades, a new U.S. government report says. The changes are unfolding in ways that are likely …
