The data of long-term ecological studies (1999–2014) are used for assessing the impact of a new Caspian invader Mnemiopsis leidyi A. Agassiz, 1865 on marine and anadromous fish species. The introduction of the ctenophore and its massive development in the Caspian Sea have mainly affected planktophagous fish, especially the most abundant species anchovy sprat (Clupeonella engrauliformis Borodin, 1904) and sturgeons (Family Acipenseridae). Mnemiopsis leidyi is one of the main negative factors preventing the restoration of the populations of Caspian fishes, especially anchovy tyulka. The critical state of the resources of the spawning parts of sturgeon populations (Family Acipenseridae) has been reinforced as a result of the massive development of M. leidyi.

TKM: Proposed North-South Railway Project - Environmental Assessment Report. Based on its 2007 Presidential Decree, the Government of Turkmenistan (GT) signed a multilateral agreement in 2007, with its neighboring countries to construct new railway tracks to develop the North-South railway corridor for promoting regional trade, cooperation and integration. This is the region’s key route for transporting bulk goods, such as oil and oil products, mineral resources, agricultural products, and textiles.
The significance of the Project is that the proposed north-south railway line will improve Turkmenistan's accessibility to Kazakhstan, the Arabian Gulf countries, the Russian Federation, and South Asia; and increase regional trade. The Project will also contribute to sustainable economic growth in Turkmenistan and development of an integrated, efficient railway system in the region. The Project will reduce the transport cost, cut travel time, and improve accessibility to rural areas of the country. This will generate benefits beyond railway transport cost and time savings.
