Marine litter, long a neglected topic, has started to garner some attention. Marine litter is composed of a diverse mix of items from various sources and so a one-size fits all solution is unlikely to be effective. Abandoned, lost and discarded fishing gear (ALDFG), shipping wastes, plastic packaging (bottles, caps, bags, etc.) and plastic manufacturing pellets are amongst the most common and persistent items found. Comparing the feasibility and the financial case for recovery versus prevention for each of these groups reveals a worrying gap in our attempts to deal with the problem. Scale of the Problem Abandoned, lost and discarded fishing … Continue reading →
Habitat loss of native species in MENA region is increasing at a sensational rate as a consequence of natural and human causes. MENA has diverse ecosystems, including aquatic and terrestrial, with different climate patterns. The region have three globally recognized hotspots; the Irano-Anatolian region, the Mediterranean forest region and the Horn of Africa region. According to 2015 IUCN Red List, approximately 2476 species in MENA are under threat comprising of mammals, fishes, birds, molluscus, amphibians, reptiles, and other species. 28% of threatened species comprises of fishes, 18% plants, 12% birds, 9% mammals and rest others. IUCN data show highest threatened species in Turkey (379), … Continue reading →
Earth Day has now grown into a global environmental tradition making it the largest civic observance in the world and is widely celebrated event in which over one billion people from over 190 countries will participate by taking suitable actions for saving our mother Earth. The Earth Day was first organized in 1970 to promote respect for life on the planet and to encourage awareness on air, water and soil pollution. Each year a different theme or topic is selected. The theme of Earth Day 2018 is ‘End Plastic Pollution’. Plastic pollution is poisoning our oceans and lands, injuring marine life … Continue reading →
Anthropogenic climate change is hindering a wide variety of organisms, their genetics and species’ habitats – in short, biodiversity. The accelerated pace of human development and its impacts on biodiversity which sustain it, is both massive and significant. Biodiversity is inextricably linked to climate; climate change is both a cause and an effect of biodiversity change. Climate change jeopardizes the services offered by the global ecosystems that have been taken for granted. Let us examine how climate change is affecting specific ecosystems. Agricultural Ecosystem Agricultural ecosystems are spread around the globe; hence, the impacts of climate change on agricultural biodiversity will be diverse and extensive. … Continue reading →
Coral reefs around the globe are highly sensitive to abiotic and biotic factors that alter the natural balance of the marine ecosystem. This in terms threatens coral species with the effect of ‘bleaching’ which is slowly destroying the coral communities. As the ecosystem deteriorates, this in turn impacts the fisheries industry which in the Arab Gulf is a major source of local revenue and a major food source for the people of the region. Artificial Coral Reefs To counteract the susceptible marine ecosystems, a very innovative and creative approach that has been tried and tested in other parts of the … Continue reading →
Mangroves are trees and shrubs that have adapted to life in a saltwater environment, usually found in the intertidal zone of a coastal or estuarine area. The halophyte characteristics of a mangrove tree allows it to grow in saline environments where no other tree can, thereby making significant contributions to the local ecosystem. Yet these reservoirs of “blue carbon” are seriously threatened. Across the globe, coastal ecosystems are currently being lost at a rate of about 2% a year – a staggering number when the carbon storage potential is considered. In a harsh desert environment such as Qatar, mangroves are one … Continue reading →
