A four-season exploration of surface water quality and trophic status in the highly dynamic waters of Karun-4 Dam Lake, SW Iran
This study explores seasonal fluctuations in water quality and phytoplankton communities within Karun-4 Dam Lake, the largest double-arch dam in the Middle East situated in Iran. Employing a systematic approach, 26 sampling stations were strategically selected to collect surface water samples at a depth of 50 cm during the midpoints of each season throughout 2019. Significant seasonal variations in water quality parameters and phytoplankton composition were observed. Predominant species included
Chrysophyceae
(38%) and
Bacillariophyceae
(32%), indicative of nutrient-rich conditions, particularly during spring and summer, as evidenced by the eutrophic state (Carlson Trophic State Index: 59.43 and 53.96, respectively). Summer exhibited the highest diversity (Shannon–Wiener Index = 2.27) and lowest evenness (Pielou’s Evenness Index = 0.21). PCA and CCA analyses revealed season-specific preferences for nutrients and ions among phytoplankton species. Water temperature emerged as a crucial factor in spring and summer, while environments with elevated bicarbonate and alkalinity levels were less favorable during winter and fall. This study provides essential insights into Karun-4 Lake's dynamic ecological conditions, underscoring the necessity for ongoing monitoring to discern long-term trends and anthropogenic impacts for effective ecosystem management.

Observation of excess heavy metal concentrations in water resources to infer surface water influences on shallow groundwater: a typical example of the Porsuk River (Eskisehir-Turkey)
The Eskisehir province is well-known due to its industrial and agricultural activities, which are a threat for the aquatic environment. Hence, monitoring of water quality in the area is of vital importance because of an excess heavy metal contents, especially As. The Porsuk River is heavily polluted by industrial activities from Kutahya city. It discharges into the Porsuk Dam and from there it flows relatively clean to Eskisehir city center, but beyond this point it increasingly deteriorates due to the negative impact of industrial and agricultural activities up to the junction point of Porsuk and Sakarya rivers. Heavy metal concentrations and As contents in surface and ground waters were selected as pollution indicators to examine pollution level and compare an interaction between river and groundwater. For this purpose, water samples taken between 2008 and 2010 from the Porsuk River along the section from the west of Kutahya to the discharge point into the Sakarya River, as well as groundwater samples from the wells located close to or far of the Porsuk River, were evaluated. Based on the obtained results, we found that the Porsuk River, especially at the locations close to the Sakarya River, and groundwater are polluted in terms of heavy metals and As compounds. In conclusion, the heavy metal and As pollution is also observed in the wells close to the locations in which groundwater is fed by the Porsuk River since it acts as an influent river. Thus, surface water is considered as a polluting source of groundwater.

The World Bank policy for projects on international waterways : an historical and legal analysis
This book deals with the evolution and context of the Bank policy for projects on international waterways. It starts with a brief description of how the Bank faced the challenges stemming from such projects, and the different approaches deliberated by the Bank that led to the issuance of the first policy in 1956. The Book then reviews the implementation experience and analyzes the principles and procedures, as well as the main features of each of the policies issued in 1956, 1965 and 1985. The principles of international water law prevailing at each stage of the policy updates are examined and compared with those of Bank policy.The book also discusses in details the notification process: its basis, by whom, to whom, its content, different riparians’ responses, and the exceptions to the notification requirement. It analyzes how the Bank handles an objection from one or more of the riparians to projects proposed for Bank financing. It also examines how the Bank has dealt with transboundary groundwater, as well as the linkages between the policy for projects on international waterways and the policies on disputed areas and environmental impact assessment. The conclusion provides an overview of the main findings of the book, and highlights some of the lessons drawn from the implementation experience of the policy.

Efficiency in reaching the millennium development goals
To reach Millennium Development Goals (MDGs) countries (or states or provinces within countries) have two options: increasing these inputs used to \"produce\" the outcomes measured by the MDGs, or increasing the efficiency with which inputs are used. This study looks at whether improvements in efficiency could bring gains in outcomes. Two chapters use world panel data to analyze country level efficiency in improving education, health and GDP (and thereby poverty) indicators. Two other chapters use province and state level data to analyze within-country efficiency in Argentina and Mexico for improving education and health outcomes. Together, the four chapters suggest that apart from increasing inputs, it is necessary to improve efficiency in order to reach the MDGs. While this conclusion is hardly surprising, the analysis helps to quantify how much progress could be achieved through better efficiency, and to some extent, how efficiency itself could be improved.

Proposals for the integrated management of the shared transboundary water resources of the Jordan River Basin
The Israelis, Palestinians, Jordanians, Syrians and Lebanese share a common geography and a common hydrology on the Jordan River Basin. This paper presents proposals for the establishment of an International Jordan River Joint Commission to manage the water quantity and quality questions of shared transboundary water resources of the Jordan River Basin. The approach proposed is to base the solution of the quantity questions on the concept of equitable apportionment to meet the minimum human and social needs for survival as expressed in the Helsinki Rules drafted by the International Law Association. It is proposed that the method of a fair and equitable water allocation defined as the Minimum Water Requirement-MWR should be equal amount of water -- 125 cubic metres/person/year, for essential human survival needs including domestic consumption and urban/industrial use with only a minimal allocation for local production of fresh vegetables. It is proposed that all five riparians share in the responsibility of managing the environmental aspects of the shared waters as well as sharing in the obligation to assist, in proportion to their available resources, those riparians -- Jordan and the Palestinians, who will be unable, in the future, to meet their Minimum Water Requirement-MWR needed for survival.

Oil: Reopening the Door
Oil-exporting nations are seeking the capital, technology and management skills of the very international oil companies they shut the door on in the 1970s. Driving the changed relationship is broadened competition for market share and needed investments that meet the double criteria of economic and environmental competitiveness. Now flat, oil demand could increase by 20 percent in the next decade, pushed by Asia's economic growth. Even with the opening of Russia, most increased production can be expected from the Middle East, maintaining that troubled region's strategic importance.
