Climate-driven ecosystem succession in the Sahara: The past 6000 years

Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a "green Sahara" to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing …

Selling two environmental services: In-kind payments for bird habitat and watershed protection in Los Negros, Bolivia

Marketing several environmental services from a single area can help access diverse sources of funding and make conservation a more competitive land use. In Bolivia's Los Negros valley (Department of Santa Cruz), bordering the Ambor

The working for water programme: evolution of a payments for ecosystem services mechanism

A payments for ecosystem services (PES) system came about in South Africa with the establishment of the government-funded Working for Water (WfW) programme that clears mountain catchments and riparian zones of invasive alien plants to restore natural fire regimes, the productive potential of land, biodiversity, and hydrological functioning. The success …

Terms of reference for preparation of detailed project report of inter basin water transfer proposals

Paying for the hydrological services of Mexico's forests: Analysis, negotiations and results

Mexico faces both high deforestation and severe water scarcity. The Payment for Hydrological Environmental Services (PSAH) Program was designed to complement other policy responses to the crisis at the interface of these problems. Through the PSAH, the Mexican federal government pays participating forest owners for the benefits of watershed protection …

Designing payments for environmental services in theory and practice: An overview of the issues

Payments for environmental services (PES) have attracted increasing interest as a mechanism to translate external, non-market values of the environment into real financial incentives for local actors to provide environmental services (ES). In this introductory paper, we set the stage for the rest of this Special Issue of Ecological Economics …

Isotope techniques to identify recharge areas of springs for rainwater harvesting in the mountainous region of Gaucher area

Environmental isotope techniques have been employed to identify the recharge areas of springs in India, in order to construct artificial recharge structures for rainwater harvesting and groundwater augmentation for their rejuvenation. A model project was taken up in the mountainous region of Gaucher

Human-induced Arctic moistening

The Arctic and northern subpolar regions are critical for climate change. Ice-albedo feedback amplifies warming the Arctic, and fluctuations of regional fresh water inflow into the Arctic Ocean modulate the deep ocean circulation and thus exert a strong global influence.

Human-induced Arctic moistening

The Arctic and northern subpolar regions are critical for climate change. Ice-albedo feedback amplifies warming in the Arctic, and fluctuations of regional fresh water inflow to the Arctic Ocean modulate the deep ocean circulation and thus exert a strong global influence.

Design aspects of Nathpa Dam

During July 1986, hydrological studies were carried out in consultation with Central Water Commission (CWC) to estimate the Probable Maximum Flood (PMF) based on snowmelt flood peak and the Probable Maximum Precipitation (PMP) in the catchment area of the Nathpa dam.

Global and regional climate changes due to black carbon

Abstract Black carbon in soot is the dominant absorber of visible solar radiation in the atmosphere. Anthropogenic sources of black carbon, although distributed globally, are most concentrated in the tropics where solar irradiance is highest. Black carbon is often transported over long distances, mixing with other aerosols along the way. …

Water: Muddy waters

India is considering an ambitious plan to link the majority of its major river basins through a vast network of canals, diverting billions of litres from the country's more water-rich river basins to those that are water-deprived. Directed by India's National Water Development Agency (NWDA), the first canal of the …

Grand Canyon flushing experiment criticised

Urban sprawl development around Aligarh city: A study aided by satellite remote sensing and GIS

Rapid urbanization causes disorganized and uplanned growth of towns and cities. The pressure of an ever growing population becomes a burden on the limited civic amenities which are virtually collapsing. Asymmetrical growth of urban centres consumes agricultural land adjacent to these, resulting in lower agricultural productivity. Besides taxing the groundwater …
