Showing results for: Ecosystems and ecosystem services
This book, by Leonard Rusinamhodzi, describes the concept of ecosystems services, shows how to identify and quantify ecosystems services in the context of sustainable food systems, and examines the challenges of maintaining ecosystems services in the face of climate change.
The first systematic analysis of marine wilderness around the world finds that only 13% of the ocean can still be classed as wilderness, i.e. having experienced low impacts from human-caused stressors such as fertilizer runoff, fishing and climate change. Only 4.9% of that wilderness (covering 0.6% of total ocean area) falls within official marine protected areas.
TEEBAgriFood, part of the UN Environment initiative The Economics of Ecosystems and Biodiversity, has released a report on the environmental, health and social costs and benefits of the agriculture and food system. It finds that the food system does not keep everyone healthy or protect the environment. It calls for a reform in how we measure food system performance, because relying on yield per hectare and market prices neglects other costs such as food-borne disease and environmental degradation.
This book, edited by John A. Herrmann and Yvette J. Johnson-Walker, explores the One Health concept, which links the health of humans, animals and ecosystems. Topics covered include the links between biodiversity and health, food and water security, zoological institutions, One Health initiatives and the social cost of carbon.
Although humans only make up 0.01% of life on Earth by weight, 83% of wild mammals and 15% of fish have been lost since the start of human civilisation, according to a new study. The study also finds that, of all mammals on Earth, 36% are humans, 60% are livestock and 4% are wild mammals, while 70% of birds are chicken and other poultry with only 30% being wild.
This open access book, edited by Kate Schreckenberg, Georgina Mace and Mahesh Poudyal, explores the link between ecosystems services and alleviating poverty. Topics include trade-offs associated with land intensification, population dynamics, governance for ecosystem health and human wellbeing, and payments for ecosystems services.
In this TED talk, ocean expert Nancy Rabalais discusses the “dead zone” in the Gulf of Mexico - an area of the ocean where there isn’t enough oxygen to support sea life. Fertiliser runoff from farmland further up the Mississippi River is causing the dead zone, according to Rabalais. She says that solutions could include growing perennial grains and using precision fertilisation.
A perspective piece and an editorial have featured in the same edition of Biological Conservation (March 2018): both tackle a recent debate among conservation biologists as to whether at a local level biodiversity or species richness is changing and in what direction.
The European Commission’s Joint Research Centre has developed a new online tool. DOPA Explorer 2.0 provides allows users to explore and compare protected areas, with regard to their species and ecosystems, and the pressures they are exposed to through human development.
This Research Handbook, edited by Mary Jane Angelo, Fredric G. Levin and Anél Du Plessis, brings together scholars from across disciplines and across the globe (including FCRN member Jonathan Verschuuren) to untangle the climate-food web and critically explore the nexus between climate change, agriculture and law, upon which food security and climate resilient development depends. It is a useful introduction to the research which is being undertaken in the area of climate change and agricultural law.
The planetary boundaries concept provides a theoretical upper limit on human activity which the planet is able to sustain without major perturbation to the current ‘Earth system’. Previously, nine planetary boundaries (PBs) have been proposed and recently Steffen et al. (2015) have updated these boundary definitions and assessed the current state of the position of human activity with respect to each boundary. In this article, researchers from a number of food, climate change, agricultural and environmental research institutions around the world build on this work by assessing the impact of agriculture on each PB status, based on a detailed literature review of the available research.
This new handbook, edited by Danny Hunter, Luigi Guarino, Charles Spillane and Peter C. McKeown, presents a comprehensive and multidisciplinary overview of the current knowledge of agricultural biodiversity.
In this article a group of American researchers provide commentary on how sustainable applications of integrated agricultural systems (IAS) can be designed to enhance all ecosystem services, without compromising the land’s resilience. The authors describe IAS as an interactive and synergistic resource transfer between multiple agricultural enterprises over space and/or time.
