This paper assesses the reflectance difference values between the
respective spectral bands in the visible and near-infrared (VNIR) of
Sentinel 2A/2B Multi-Spectral
Instrument (MSI) and Landsat 8/9 Operational Land Imager (OLI) sensors for seagrass, algae, and
mixed species discrimination and monitoring in a shallow marine environment
southeast of...

This paper assesses the reflectance difference values between the homologous visible and near-infrared (VNIR) spectral bands of Sentinel-MSI-2A/2B and Landsat-OLI-8/9 sensors for seagrass, algae, and mixed species discrimination and monitoring in a shallow marine environment southeastern of Bahrain in the Arabian Gulf. To achieve these, a field sur...
Seagrass beds play an important role in carbon storage, as well as an effective removal of CO2 from the "biosphere-atmosphere" system, which plays a significant role in the amelioration of climate change impacts. The present study focused on carbon content modeling and mapping in submerged aquatic vegetation (SAV) including seagrass and algae speci...

An integrated environmental assessment of the Askar environ, Kingdom of Bahrain using DPSAIR framework
Submerged aquatic vegetation (SAV) comprised of mixed seagrass and algae species in shallow water has gathered more attention in recent studies at local, regional, and global scales. The objective of this research is to validate and to investigate the potential of several spectral indices for percentage of submerged aquatic vegetation cover (PSAVC)...
The coast of Askar is one of the common fishing grounds exposed to several anthropogenic activities. Twenty-seven monitoring stations have been selected to assess the total petroleum hydrocarbons (TPHs) in Askar coastal sediments. The stations are distributed into three sectors; one is associated with intertidal zone and other two are associated wi...
Seagrass (Halodule uninervis and Halophila stipulacea) and algae (green and brown) species are widely distributed along the coastal zones of the Bahrain national water. In this study the potential of Landsat-OLI VNIR spectral bands was investigated for distinction and discrimination among these species using spectral reflectances. The measured spec...
Stock of the spangeld emperor (Lethrinus nebulosus) sampled from commercial catches at Al-Freya landing site in the Jubail marine wildlife sanctuary, east of Saudi Arabia, was assessed from April 2012 to January 2013.
Accumulation of 8 heavy metals (HM), Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn, was assessed in the leaves and sediments of gray mangrove ( Avicennia marina (Forsk.) Vierh.) at three sites along Tubli Bay using Inductive Coupled Plasma Analyzer. The results showed no significant differences in HM contents in the leaves of mangroves between the sites excep...
This research was conducted in four sites at Mahazat as-Sayd reserve in Saudi Arabia to determine the optimum habitats’ constituents for Asian houbara bustard
Chlamydotis macqueenii
via assessing abiotic and biotic factors with special reference to vegetation aspects. Vegetative parameters were quantified using combinations of distance and line int...
Jabel Samhan reserve in the mountains of Dhofar of Sultanate Oman is characterized by being a habitat for frankincense trees Boswellia sacra Flueck that are exposed to anthropogenic and natural pressures; which endanger trees survival. The present study aims to conduct an integrated environmental assessment of frankincense tree stands using DPSIR f...
The present paper is concerned with annual catch of commercial fisheries in the Kingdom of Bahrain 2004-2009 based on landing statistics provided by the General Directorate for the Protection of Marine Resources.
An integrated environmental assessment of rangeland resources in Jabal Samhan protectorate area of Dhofar, Sultanate of Oman was conducted using DPSIR analysis matrix. Assessment included monitoring current state and direction of rangeland resources, direct and indirect pressures influencing resources and their impacts. Effectiveness of government...
A Vegetation survey aimed at the estimation of species and community parameters was conducted for Mangrove assembly along the coasts of Tubli Bay of Bahrain. Satellite imagery (IKONOS) coupled with ground truthing were used to calculate the areas of the Mangrove. Results showed that Mangrove coverage and density at Sanad site were 70% and 1245 tree...
نظرا لمحدودية مساحة مملكة البحرين وقلة الموارد المعدنية فيها، فقد واجه قطاع البناء والتشييد مشكلة توافر الرمال اللازمة لعمليات التنمية الحضرية السريعة التي واكبت الطفرة الاقتصادية والاجتماعية التي شهدتها المملكة خلال العقود الثلاثة الماضية. وقد تغلب على هذه المشكلة من خلال سحب الرمال البحرية أو تجريفها (Dredging) من المياه الإقليمية الضحلة التي تتو...

this assessment, the UNEP Secretariat and the authorsprovide an objective evaluation and analysis designed tosupport environmental decision making. Expert judgmentis applied to existing knowledge to provide scientificallycredible answers to policy-relevant questions.
Environmental governance is the mechanism through which peace and resilience can be realized in West Asia. Good governance implies that issues such as conflict resolution, food, water and energy are examined in a holistic framework. Economic, social and environmental spheres must be integrated into a multi-sectoral policy design within the goals of sustainable development.
Sustainable growth in the economies of West Asia will enable progress on food security, sustainable water sources, reduced vulnerability to natural and man-made disasters, reduced risks of climate change, permanent energy solutions and conservation of natural resources. The outlook calls for concerted efforts by governments, civil society and the private sector in West Asia to address environmental challenges in the region.
