Showing results for: Biodiversity and ecosystems
With large scale habitat loss, overharvesting, climate change and invasive species affecting most regions in the world, many thousands of animal and plant species are at risk of extinction due to human actions. The food system is the primary driver of biodiversity loss and ecosystem degradation. At the same time, food production is closely interlinked with and dependent on the continued existence of specific natural areas, because it relies on ecosystem services such as pollination, fish stock renewal and rain water cycling and countless others.
This paper by researchers from the USA, UK and Mexico examines the biodiversity conservation and carbon storage implications of a number of land-use scenarios related to cattle ranching in Yucatán, Mexico.
Geoengineering to fix climate change could harm biodiversity, according to two modelling studies.
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.
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.
This new book by Bioversity International summarizes the most recent evidence on how to use agrobiodiversity to provide nutritious foods through harnessing natural processes.
This paper models human and natural influences on the global capture of wild marine fish. The researchers show that wild fish harvest increases during the 20th century were most likely explained by improvements in fishing technology. Their simulated future projections, that assume ongoing technological progress and open access (i.e. no policy constraints), suggest a long-term decrease in harvest due to over-fishing.
This paper in Biological Conservation argues that the role of pesticides in driving biodiversity loss deserves renewed emphasis, quantification and amelioration. The authors present their views on how conservationists should support integrated approaches, for sustainable agriculture and rural development planning, that simultaneously address food security, pesticide use and biodiversity conservation.
Planetary health is a new approach that broadens health research to include the health of human civilisations and the natural (external) systems on which they depend. In a new journal, alongside The Lancet Public Health and The Lancet Global Health, The Lancet Planetary Health will explore the links between planetary and human health and how we can protect the environment on which we depend and develop sustainable systems that support human health.
In the latest in a series of articles seeking to shake up the conversation about food production and its trade-offs (see for example our previous summary of Elena Bennett’s Nature commentary, and the subsequent FCRN discussion forum), this opinion piece seeks to shift the focus of the discourse away from food production as the goal of agriculture, and towards food security, incorporating biodiversity outcomes.
This paper argues that the strength of the linkages between the ‘Human System’ and the Earth system warrants a new paradigm of modeling which incorporates key factors in one system as variables of a model of the other.
