Showing results for: Agricultural biodiversity
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.
This paper, taken from an inaugural edition on planetary health in the Lancet, analyses global food and nutrient production and diversity by farm size, providing evidence on how smallholder farmers contribute to the quantity and quality of our global food supply and discussing the structural impacts of agriculture on nutrient availability.
This review assesses the performance of organic cropping systems as an approach to sustainable agriculture, and seeks to identify the contextual considerations (such as type of cropping system) that may affect this performance. The scope of the review is constrained to the level of the farming system (i.e. excludes considerations of other components of the food system, such as packaging or transport). In order to provide an unbiased assessment of organic farming as a means of sustainable agriculture, rather than approaching the question from the usual “What does organic farming do well/badly?” angle, the authors ask “What constitutes successful sustainable agriculture?” then measure organic farming against this yardstick.
This paper makes an important methodological contribution to the highly disputed debate about whether the net effect of agricultural intensification on biodiversity is positive or negative. What is already known is that there is clear relationship between increased agricultural intensification and decreased biodiversity on the land that has been intensified.
Initiated in 1999, the Grain-for-Green Program was set up primarily to reduce soil erosion and uses cash payments to incentivise people to replant trees on sloped crop and scrubland. This study examines the effects on bird and bee species in the scheme across the country. It finds that the program has not greatly benefited birds and bees due to the common practice of monoculture tree planting.
This editorial article focuses on an aspect of agricultural food loss and waste, not often considered: the effects that a reduction in food loss and waste at the production stage, might have on the species that have become reliant on food waste.
In this modelling study, the authors examine potential trade-offs between sufficient food provisioning in the future and sustaining biodiversity. On the one hand they find that cropland expansion increases food security, particularly in areas which are currently struggling with access to safe and nutritious food.
Researchers from Conservation International have found a small island near Timor-Leste with staggering species richness. Atauro Island, home to about 8,000 people sits in the middle of the so-called Coral Triangle, known for its biodiverse marine environments.
The OneHealth project, launched in 2015, explores the relationship between infectious diseases, biodiversity and ecosystems, the economics of disease and disease drivers, and the impacts of climate change and demography on health.
This report by members of the Environmental Pillar and Stop Climate Chaos aims to better inform discussions across civil society, media and government, and at EU policy level, regarding Ireland’s climate, energy, and wider environmental responsibilities.
Biofuel policies have been a major driver of rising prices for biofuel crops around the world, such as rapeseed, corn and soy. In this paper researchers take France as an example and show that a tax of €0.05–0.27 per kg of fertiliser could help to limit French farmers’ use of fertiliser (driven by the high rapeseed prices resulting from biofuels policy).
This paper presents biodiversity scenarios as a useful tool to help policymakers predict how flora and fauna will likely respond to future environmental conditions. Although changes to land use are a major driver of biodiversity loss, the study finds that scenarios focus overwhelmingly on climate change. The researchers argue that this imbalance makes scenarios less credible, and they make recommendations on how to improve and make more plausible projections.
