The original application was registered suo-motu based on the news item titled "Nayar …Reduced streamflow in water-stressed climates consistent with CO2 effects on vegetation
Global environmental change has implications for the spatial and temporal distribution of water resources, but quantifying its effects remains a challenge. The impact of vegetation responses to increasing atmospheric CO2 concentrations on the hydrologic cycle is particularly poorly constrained1, 2, 3. Here we combine remotely sensed normalized difference vegetation index …River–human harmony model to evaluate the relationship between humans and water in river basin
With the rapid population growth, ecological pressure caused by human activities on rivers is growing. Decision makers are often faced with the dilemma of how to maintain economic growth while also maintaining the resources of a river and its environment. In this study, a model has been proposed for the …Order of the National Green Tribunal regarding projects in the Netravathi basin across river Netravathi and its tributaries, Dakshina Kannada and Hassan Districts in Karnataka, …
Order of the National Green Tribunal (Southern Zone, Chennai) in the matter of M/s. A. Purushottam Chitrapur, Vs. Union of India & Others dated 07/09/2015 regarding projects in the Netravathi basin across river Netravathi and its tributaries / streams in Dakshina Kannada and Hassan Districts in Karnataka.Enhancing the climate resilience of Africa’s infrastructure: the power and water sectors
This book evaluates -using for the first time a single consistent methodology and the state-of-the-art climate scenarios-, the impacts of climate change on hydro-power and irrigation expansion plans in Africa’s main rivers basins (Niger, Senegal, Volta, Congo, Nile, Zambezi, Orange); and outlines an approach to reduce climate risks through suitable …Integrated water resources management in Central and Eastern Europe: IWRM versus EU Water Framework Directive
The countries of Central and Eastern Europe faced the challenges of becoming EU Member States. In the water sector, the environment and water quality requirements of the EU Water Framework Directive (WFD) dominate water resources planning and management. Many see this as a surrogate for IWRM, although IWRM has a …Good practices for regulating wastewater treatment: legislation, policies and standards
This UNEP publication presents a critical analysis of successful cases for regulating wastewater treatment and management in six countries - Argentina, Austria, Finland, Jordan, Singapore and South Africa. It reviews procedures and processes in the implementation of wastewater legislation and may be useful for other countries in addressing the global …A water-secure world for all - water for development: responding to the challenges
The Stockholm World Water Week’s focus on “Water for Development” comes at an opportune time. Water as a sector in world affairs is reaching a tipping point. Over the next two decades and more, the global push for food and energy security and for sustaining urbanization will place new and …Question raised in Lok Sabha on inter-state river water sharing disputes, 06/08/2015
Question raised in Lok Sabha on inter-state river water sharing disputes, 06/08/2015. On the complaint made by the State Governments, the Central Government has, so far, set up 08 Tribunals to settle water disputes among the States under the Inter-State River Water Disputes (ISRWD) Act, 1956. The present status of …Question raised in Rajya Sabha on Integrated Ganga Conservation Programme, 03/08/2015
Question raised in Rajya Sabha on Integrated Ganga Conservation Programme, 03/08/2015. The Cabinet approved the Namami Gange program on 13th May, 2015 as a comprehensive approach to rejuvenate the river Ganga by inclusion of all tributaries under one umbrella. The program envisages 100% central government funding. Details and salient features …Evaluation of spatial pattern of altered flow regimes on a river network using a distributed hydrological model
Alteration of the spatial variability of natural flow regimes has been less studied than that of the temporal variability, despite its ecological importance for river ecosystems. Here, we aimed to quantify the spatial patterns of flow regime alterations along a river network in the Sagami River, Japan, by estimating river …Hydrologic sensitivity of flood runoff and inundation: 2011 Thailand floods in the Chao Phraya River basin
The Thailand floods in 2011 caused unprecedented economic damage in the Chao Phraya River basin. To diagnose the flood hazard characteristics, this study analyses the hydrologic sensitivity of flood runoff and inundation to rainfall. The motivation is to address why the seemingly insignificant monsoon rainfall, or 1.2 times more rainfall …Agriculture intensifies soil moisture decline in Northern China
Northern China is one of the most densely populated regions in the world. Agricultural activities have intensified since the 1980s to provide food security to the country. However, this intensification has likely contributed to an increasing scarcity in water resources, which may in turn be endangering food security. Based on …Groundwater prospecting in Deccan traps covered Tawarja basin using Electrical Resistivity Tomography
Acute shortage of water supply for domestic and irrigation purposes in hard rock area is accentuated by occurrence of groundwater in limited quantity within sparsely distributed aquifers characterised with secondary porosity of finite areal extent. Tawarja river basin is in drought prone Latur district of India falling in basaltic Deccan …Assessment of hydroclimatic condition in extensive groundwater mining area, Southern India
The study highlights the climatic water balance, drought assessment and agricultural potentiality of Uppar Odai sub-basin located in the Southern part of India, Tamil Nadu state. The average annual precipitation in the sub-basin is 625 mm, which is much lower than the state average rainfall (970 mm). It has been …Assessment of snowmelt runoff in the eastern Himalayan region under climate change scenarios
In Eastern Himalayan region, snow melt is the major source of fresh water. Also, snow covered areas lying at low altitudes are expected to be most vulnerable to global warming. Thus, assessment of the snowmelt runoff under different climatic scenarios is important for efficient management and planning of water resources, …Uncertainty in global groundwater storage estimates in a total groundwater stress framework
Groundwater is a finite resource under continuous external pressures. Current unsustainable groundwater use threatens the resilience of aquifer systems and their ability to provide a long-term water source. Groundwater storage is considered to be a factor of groundwater resilience, although the extent to which resilience can be maintained has yet …Changing pattern of heavy rainstorms in the Indus basin of India under global warming scenarios
Estimation of extremely high rainfall (point or areal) is one of the major components of design storm derivation. The estimation of Probable Maximum Precipitation (PMP) involves selection of heavy rainstorms and its maximization for the moisture content during the rainstorm period. These heavy rainstorms are nothing but the widespread heavy …Incorporating local institutions in irrigation experiments: evidence from rural communities in Pakistan
Many irrigation systems are special cases of common-pool resources (CPRs) in which some users have preferential access to the resource, which in theory aggravates collective action challenges such as the under-provision of necessary infrastructure as a result of unequal appropriation of water resources. We present experimental evidence based on an …Report on Tawang river basin study: cumulative impact assessment of proposed hydel power projects, determination of basin carrying capacity, and landscape level biodiversity management plan
While considering the accordance of forest clearance for 750 MW Tawang-I and 750 MW Tawang-II projects, the Forest Advisory Committee (FAC) of the Ministry of Environment and Forests, (MoEF and CC) asked the Government of Arunachal Pradesh to conduct a study on Tawang river basin with the following objectives: To …The power of rivers: finding balance between energy and conservation in hydropower development
The Nature Conservancy’s white paper, “The Power of Rivers: Finding balance between energy and conservation in hydropower development,” addresses the global expansion of hydropower dams and the need to find development scenarios that provide energy, but also work for communities and nature. Designed as a resource for hydropower companies, governments, …
