Corals and coral-associated species are highly vulnerable to the emerging effects of global climate change. The widespread degradation of coral reefs, which will be accelerated by climate change, jeopardizes the goods and services that tropical nations derive from reef ecosystems. However, climate change impacts to reef social-ecological systems can also be bi-directional.For example, some climate impacts, such as storms and sea level rise, can directly impact societies, with repercussions for how they interact with the environment.
In March 2015, regional Pacific stakeholders and Governments engaged in collaborative planning to establish a new direction in the management of Coastal Fisheries. A New Song for Coastal Fisheries: Pathways to Change calls for a “...new and innovative approach to dealing with declines in coastal fisheries resources and related ecosystems”. A New Song is an important step forward for coastal fisheries management across a complex and diverse region. This paper argues that a strategic and integrated approach to capacity development, learning and training will support its full implementation.
Suspending horticulture in sacks above the ground can result in higher levels of productivity for vegetables when the challenges of unfertile or saline soil, flooding, waterlogging, and land and water constraints are regularly encountered. Previously used feed and fertilizer sacks are filled with a high-productivity soil mixture. Vegetables are grown on the top and/or in holes cut into the sides of the sacks. While growing vegetables in sacks has existed for many years in Bangladesh, the technique has been modified by WorldFish in collaboration with farmer researchers.
A habitat is the environment where species such as fish live, feed and breed. A small, specialized area of a habitat (a microhabitat) can be created and managed as a way to attract and encourage a species to use the environment. These microhabitats help maintain the biodiversity of ecosystems, which in turn support livelihood activities and the production of food. This brief describes the use of fish ring microhabitat developed by WorldFish for use in rice fields in Bangladesh and its benefit.
Leadership is heralded as being critical to addressing the “crisis of governance” facing the Earth's natural systems. While political, economic, and corporate discourses of leadership have been widely and critically interrogated, narratives of environmental leadership remain relatively neglected in the academic literature. The aims of this paper are twofold. First, to highlight the centrality and importance of environmental science's construction and mobilization of leadership discourse.
The main objectives of the paper were to assess the adequacy of the micronutrient intakes of lactating women in a peri-urban area in Nepal and to describe the relationships between micronutrient intake adequacy, dietary diversity and sociodemographic variables.
Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) seeks to reduce poverty and improve food security for many small-scale fishers and farmers who are dependent on aquatic agriculture systems by partnering with local, national and international partners to achieve large-scale development impact. This study on promising practices in food security and nutrition assistance to vulnerable households in the Tonle Sap region forms part of the preliminary research that informs AAS work in the highly productive Mekong Delta and Tonle Sap Lake floodplain.
The challenge to manage coastal resources within Asia-Pacific's Coral Triangle has gained global attention. Co-management is promoted as a key strategy to address this challenge. Contemporary community-based co-management often leads to ‘hybridization’ between local (customary) practices, and science-based management and conservation. However, the form of this hybrid has rarely been critically analysed. This paper presents examples of co-management practices in eastern Indonesia and Solomon Islands, focusing in particular on area closures.
Small-scale fisheries present challenges to management due to fishers’ dependency on resources and the adaptability of management systems. The authors compared social-ecological processes in the sea cucumber fisheries of Zanzibar and Mayotte, Western Indian Ocean, to better understand the reasons for resource conservation or collapse.
