Certain key water quality parameters were showing considerable increase in their values from Badwala to Etawah. The highest value of chloride was observed at Mathura (217.4 ppm). The fish diversity of the river Yamuna were investigated for the first time and 112 fish species belonging to 10 orders, 29 families and 73 genera were identified. Indian major carp fishery has considerably declined in the system while exotics, especially Cyprinus carpio and Oreochromis niloticus, are increasing at an alarming rate in the middle and downstream stretches. The exotic common carp was observed at all sampling sites except the uppermost, almost pristine Badwala and formed a maximum 27.0% of the total fish catch at Arail (Allahabad), Tilapia was recorded between the Panipat to Allahabad stretch, and formed a maximum...

Both rivers originate above 550 m above sea level in the Vindhya region. An interlinking project proposed for the rivers envisages diversion of water from Ken basin to the Betwa. The river sediment is alkaline and dominated by sand (78–89%) in both rivers. Oxygen-rich alkaline water and moderate values of chemical parameters show the pollution free and productive nature of both the rivers. There was no statistically significant difference in water quality between the Ken and Betwa rivers, except for total alkalinity. The biotic parameters were observed in similar ranges and moderate condition. A total of 61 planktonic forms were recorded from the rivers out of which 55 were phytoplankton. For the first time, 89 fish species belonging to 10 orders, 26 families, and 62 genera have been recorded in the river Ken, while 81 species classified under 10 orders, 24 families, and 55 gener...

Altogether 92 fish species representing 8 orders, 23 families and 64 genera were recorded. The most dominant family was Cyprinidae with 47 species (51%) followed by Bagridae with 7 fish species (8%). Labeo was the most dominant genera with 9 species, followed by Barilius (6), Garra and Mystus (4 species each). Species richness showed a trend of rapid decline along the altitude with highest records in the lowland sites, where ~93% of the total fish species recorded were between 138 and 320 masl. The Shannon Wiener Index (H’) was found to be maximum at R6 (3.254) followed by R7 (3.24) and R8 (3.074) sites, all constituting the lowland stretch of the river. Species composition showed a distinct assemblage of cold-water specific genera at higher elevatio...

An investigation was carried out in six sites at (Itahara, S1), (Madhavgarh, S2), (Bakiya upstream, S3), (Bakiya downstream, S4), (Chakghat, S5) and (Panasaghat, S6) of the river to document the fish diversity, seasonal variability, and impact of environmental variables on fish species composition during the period 2017 to 2019. Altogether 75 fish species belonging to 54 genera, 23 families, and 10 orders were recorded. Fish species richness at (S1), (S2), (S3), (S4), (S5), and (S6) and was recorded as 9, 39, 38, 13, 61, and 49, respectively. Family Cyprinidae with 31 species contributing 41% was the most dominant family, followed by Bagridae (8%) and Schilbeidae (6.7%). Seasonal variation in fish species richness and diversity indices were observed in the river stretch. Maximum species richness (45)...

Connectivity in the sub-region has gained severe traction in recent times. For instance, several bilateral agreements, the revival of routes and construction of economic corridors to facilitate seamless movement of goods and passengers have been initiated.

The paper briefly traces the evolution of Indo-Iran engagements and also analyses their respective macroeconomic parameters. It also outlines and discusses three major geopolitical and geo-economic influences including sanctions on Iran, payment mechanism, and Iran’s business environment. Moreover, the issues pertaining to access to oil, transit route through Afghanistan and other trade facilitation measures have also been discussed. The paper also uses the revealed comparative advantage index to identify some potential areas of cooperation. Also, it argues that India needs to be more cautious and pragmatic in its strategic endeavours.

This shift has called into question the dominant position of the US in the region, as China challenges the US both economically and militarily. India's role in southwest Asia. sharing a disputed border with China and now more engaged in Southeast and East Asian affairs has added to the complexity of security relationships. More recently, maritime territorial disputes in the South China Sea, impacting both ownership of resources and freedom of navigation of critical sea lines of communication, have increased volatility in the region, as China's so-called 'peaceful rise' is no longer viewed as being all-benign. As a result, Indo-Pacific countries are reformulating their individual strategic contours by entering into bilateral, and in some cases multilateral, security and geo-strategic arrangements. The United States has also reacted to this changing strategic landscape, announcing in 2011 a 'pivot' or 'rebalance' to Asia to ensure it remains engaged and relevant in the region. This paper will discuss the trajectory of Indo-Pacific security relationships, analysing the evolving strategic construct, cooperation, friction and challenges.27 page(s

To maintain the river in moderate condition and to keep basic ecosystem functions intact, at least 18.9% of mean annual runoff (MAR) has been estimated, while the actual discharge of the river was merely 5.16% of MAR. The river presently holds 89 fish species, but 20 species reported in an earlier study were not observed, while 14 new fish species were encountered. Sediments, water and macro-benthic biota of the river were also studied to know the effect of low discharge.
