The present study investigated diffusive emissions of methane (CH4) and nitrous oxide (N2O) to the atmosphere from three relatively small (3–120 km2) reservoirs (Masinga, Kamburu and Gitaru) on the Tana River (Kenya). Sampling was conducted biweekly in 2011, 2012 and 2013, at sampling sites upstream and downstream of these reservoirs while five sampling campaigns were carried out in 2011, 2012 and 2013 for different sites within each of the reservoirs.
The principle purpose of this report is to provide recommendations, advice and practical guidance, for establishing programmes to monitor and assess the distribution and abundance of plastic litter, also referred to as plastic debris, in the ocean.
The UN General Assembly has made a unanimous decision to start negotiations to
Complex social-ecological interactions underpin many environmental problems. To help capture this complexity, we advance an interdisciplinary network modeling framework to identify important relationships between people and nature that can influence environmental conditions.
Environmental flows improve water management by ensuring a sustainable water supply meets the needs of people, agriculture, energy, industry and the environment within the limits of availability. The application of environmental flows supports the health of aquatic ecosystems and the well-being of people who depend on them. By providing a system for equitable allocation of water, based on available supply, the application of environmental flows can support development and poverty alleviation.
Without drastic efforts to reduce carbon emissions and mitigate globalized stressors, tropical coral reefs are in jeopardy. Strategic conservation and management requires identification of the environmental and socioeconomic factors driving the persistence of scleractinian coral assemblages—the foundation species of coral reef ecosystems. Here, we compiled coral abundance data from 2,584 Indo-Pacific reefs to evaluate the influence of 21 climate, social and environmental drivers on the ecology of reef coral assemblages.
Pollution from land-based run-off threatens coastal ecosystems and the services they provide, detrimentally affecting the livelihoods of millions people on the world's coasts. Planning for linkages among terrestrial, freshwater and marine ecosystems can help managers mitigate the impacts of land-use change on water quality and coastal ecosystem services.
In August, the Ninth Conference of Parties to the Nairobi Convention adopted Decision CP.9/6 on Ocean Governance, urging parties to work with regional bodies to implement AMCEN’s Cairo Declaration, the 2050 Africa Integrated Maritime Strategy, and the provisions of Agenda 2063 on ecosystem-based management approaches. The decision also requested the Secretariat to contribute to the development of an African strategy on ocean governance.
World Oceans day was 8 June, 2019. This year, the Nairobi Convention celebrated by releasing information on major issues facing the Western Indian Ocean (WIO) region and how the Contracting Parties are working to sustainably protect, manage, and use their marine and coastal resources.
