Saving the Hilsa by letting the Narmada flow!
This study proposes a novel method to determine optimum freshwater release from the Sardar Sarovar Dam to minimise the negative impact on hilsa fish migration in downstream estuaries. Posted on 20 Apr, 2024 08:17 AM

While dams are said to play a crucial role in meeting growing water demands, generating energy, and protecting from floods, controlled water release from dams can significantly impact the ecosystem of estuaries and the fish living in its waters.

Understanding drought impacts and strategies: Orange growers in Vidarbha
Discover the systematic strategies employed to mitigate water scarcity and adapt to climatic adversities Posted on 19 Apr, 2024 03:50 PM

Drought, a climatic phenomenon marked by insufficient rainfall over an extended period, severely impacts livelihoods by causing water shortages for essential activities like farming. This leads to reduced agricultural income, livestock mortality, food insecurity, and health issues.

Collaborative approaches to water governance in Indus, the Ganga and the Brahmaputra basin
As the demand for water from the Hindu Kush Himalaya region is expected to rise due to population growth, the impacts of temperature increases, and development requirements, researchers emphasise the urgent need to enhance scientific collaboration and rejuvenate existing treaties and governance structures. Posted on 18 Apr, 2024 09:05 AM

The future of over one billion people and globally significant ecosystems hinges on collaborative efforts to address the challenges posed by climate change and water management in three critical river basins: the Indus, the Ganga, and the Brahm

Role of irrigation in improving farm efficiency in tribal villages of Eastern India
This study found that irrigation, mainly surface irrigation played an important role in improving farm efficiency, but was only accessible to farmers living in the plains. Posted on 13 Apr, 2024 03:21 PM

Agricultural productivity continues to be low in South Asian economies such as India. For example, the average paddy production per hectare in India is 3590 kg, which is much lower compared to 6686 kg per ha.

Mapping groundwater in drought prone Marathwada
Mapping groundwater potential zones (GWPZ) can greatly help in efficient groundwater management through careful use and identifying areas for construction of recharge structures to improve groundwater resources in the region. Posted on 12 Apr, 2024 10:16 AM

As high as  0.6 million Indians suffer from high to very high water stress because of insufficient availability of freshwater.

Himalayan lakes, under stress!
Despite the large dependence of the increasing population on Himalayan lakes, information on the lakes continues to be limited thus hindering their sustainable management. Posted on 31 Mar, 2024 09:19 PM

Freshwater lakes in the Indian North Western Himalayan region (INWH) are unique and an important source of water for the growing population in the region. The INWH region covers the two states of Uttarakhand and Himachal Pradesh and two union territories of Jammu and Kashmir, and Ladakh in India.

Heat stress among salt pan workers of Tamil Nadu
This study finds that heat stress can increase the risk of salt pan workers to a number of health hazards. Posted on 25 Mar, 2024 01:47 PM

Climate change is expected to increase temperatures by at least 1.5 C around the globe thus increasing the frequency and intensity of heat waves. Increased heat will have a considerable impact on the working population, particularly manual labourers who work in outdoor settings.

Can traditional tanks help Bengaluru revive its declining groundwater levels?
A study that examined the contribution of tanks in groundwater recharge in urban Bengaluru found that presence of more impermeable surfaces in the city led to some amount of groundwater recharge from tanks, but was influenced by location, area concerned, water level fluctuations and alternative recharge sources available. Posted on 19 Mar, 2024 11:21 PM

Can traditional tanks help Bengaluru in reviving its groundwater levels and in preventing the growing water crisis that the city is currently facing?
