“…Gradually, these wells extracted non-renewable groundwater from surficial unconfined aquifers and from desert aquifer containing non-renewable groundwater with severe drops in their water levels (Figure 1). In addition to declining groundwater levels over-exploitation has resulted in ceasing of spring and seepage discharges along wadis and to desert oasis such as Azraq and Taba with dramatic impacts on biodiversity and irrigated farming and livestock (Alhejoj et al, 2014(Alhejoj et al, , 2017 (Figure 2). Agriculture based on the extraction of non-renewable groundwater in Jordan is of low-value (Taimeh, 2015) and can in no way cover the cost of substituting the extracted water, which is only possible in the case of Jordan by desalinating sea water at Aqaba and transferring it to the depleted aquifers.…”

This study discusses the present water security situation in Jordan and delineates the required policies and programs to reach at a more robust and resilient water security situation. Although Jordan has achieved much in securing the different components of its water sector system, some components have still to be adequately addressed and others strengthened. Increasing the available water resources, which is practically only possible by desalinating sea water at Aqaba under sole Jordanian sovereignty, is found to be the most important and vital issue in improving the country's water security situation. It improves the security issues of providing dearly needed additional water, releases the overexploited aquifers and saves them from depletion and quality deterioration, allows introducing new industries to Jordan, de-sharpens the conflict on the shared water resources with Jordan's neighboring countries and is expected to render these conflicts to a problem of royalty on water resources and not as it is at present a social, economic, human, environmental and political conflict. Desalination will also make Jordan more resilient to climate change. Infrastructure security must be strengthened in Jordan both against natural hazards and against intended sabotage and damage. Water quality protection from pollution and deterioration has still to be adequately addressed requiring strengthening of laws and regulations and their application. The already delineated surface and groundwater protection zones have to be strictly adhered when licensing human activities in addition to implementing cybersecurity best practices. In addition, technology-dependent management tools have to be strongly advanced using integrated water re-How to cite this paper: Salameh, E.

“…A number of nominal species have already been synonymised under T. jordani based on similarities in shell morphology and overlapping distribution ranges. These include N. michonii Bourguignat, 1852, N. karasuna Mousson, 1874, and N. orontis Blanckenhorn, 1897(Martens 1879, Alhejoj et al 2017. Moreover, Sands et al (2019a) suggested that T. niloticus (Reeve, 1856) from the Nile River, Egypt (which has been considered a potential synonym of N. africana Reeve, 1856;Brown 1994) is conspecific with T. jordani on the basis of molecular data-something additionally supported by Glöer (2019).…”

“…It plays an important role in the ecology of freshwater ecosystems by managing the growth of certain algae and acting as a food source for other organisms (Kiss-József Rékási and Richnovszkyt 1995;Lappalainen et al 2001;Råberg and Kautsky 2008;Peters and Traunspurger 2012). Species of Theodoxus can be used as indicators of environmental health (Alhejoj et al 2017) and setting (Moissette et al 2016), which is of particular usefulness to (palaeo)ecologists. Moreover, some species are known to act as hosts for a number of trematodes and ciliates, which is of broad interest to parasitologists (Raabe 1968;Abdel-Hafez and Ismail 1987).…”

Asia contains a high species diversity of the freshwater gastropod genus Theodoxus. Recent molecular and morphological reviews of this diversity have uncovered a number of yet undescribed species while suggesting the urgent revision of several others. Moreover, some of these studies have indicated a number of species previously not recorded for this continent. Despite the advancements, a taxonomic revision and an update on the distribution of Theodoxus spp. in Asia is still pending. Here, we construct the most robust phylogeny of Theodoxus up to now and review original descriptions, type material, recent taxonomic revisions, compendia, and species lists to provide a comprehensive checklist of all known extant Asian Theodoxus spp. Our checklist also provides descriptions for three recently discovered and yet undescribed species (Theodoxus gurur Sands & Glöer, sp. nov., Theodoxus wesselinghi Sands & Glöer, sp. nov., and Theodoxus wilkei Sands & Glöer, sp. nov.), as well as shows the need to synonymise several previously described morphospecies. The present revision recognizes 14 extant Theodoxus spp. for Asia. Some of these species are widespread, while others are endemic to just a single location. Based on the revised and new distribution data, we provide updates and new assessments of species conservation statuses.

“…As such, these aquatic macrozoobenthic organisms are well-suited indicators of environmental conditions in aquatic regions (Bahtiar et al 2022;Foster et al 2022). When an area's environment becomes contaminated, these organisms also become polluted by accumulating pollutants in their bodies, corresponding to the environmental pollutant concentrations (Alhejoj et al 2017). A higher macrozoobenthic diversity index within a certain environment indicates that the aquatic area remains in good condition, whereas lower macrozoobenthic diversity indicates light to severe pollution (Harahap et al 2018;Herawati et al 2020).…”

Abstract. Mawardi AL, Khalil M, Sarjani TM, Armanda F. 2023. Diversity and habitat characteristics of gastropods and bivalves associated with mangroves on the east coast of Aceh Province, Indonesia. Biodiversitas 24: 5146-5154. Mangrove areas are vital for various gastropod and bivalve species as breeding, nursery, and stable nutrient supply grounds. This study aims to understand the habitat characteristics and diversity index of gastropods and bivalves and identify the associated species with mangrove vegetation along the east coast of Aceh Province, Indonesia. This research utilized a survey method with gastropod and bivalve sampling conducted using purposive sampling. Sampling was carried out at 6 research locations with varying environmental conditions. Gastropods and bivalves were collected from each research location using 1 m x 1 m plots. All collected gastropod and bivalve samples were preserved in a 4% formalin solution and later identified at the Biology Laboratory of Samudra University. A total of 5,293 individuals of gastropods and bivalves were found in the research locations, comprising 48 species and 21 families. The diversity index of gastropods and bivalves across all research locations showed a moderate criterion, indicating slight pollution on the east coast of Aceh Province. The highest diversity was observed at location 5, far from settlements and active fishing vessel activities. On the other hand, the lowest diversity was found at location 2, an area with active fishing vessel transportation to and from the fish auction site (TPI).
