The western honey bee (Apis mellifera) is the most frequent floral visitor of crops worldwide, but quantitative knowledge of its role as a pollinator outside of managed habitats is largely lacking. Here we use a global dataset of 80 published plant–pollinator interaction networks as well as pollinator effectiveness measures from 34 plant species to assess the importance of A. mellifera in natural habitats....
The Global Land Outlook is billed as the most comprehensive study of its type, mapping the interlinked impacts of urbanisation, climate change, erosion and forest loss. But the biggest factor is the expansion of industrial farming.
The impacts vary enormously from region to region. Worst affected is sub-Saharan Africa, but poor land management in Europe also accounts for an estimated 970m tonnes of soil loss from erosion each year with impacts not just on food production but biodiversity, carbon loss and disaster resilience. High levels of food consumption in wealthy countries such as the UK are also a major driver of soil degradation overseas...
This assessment on pollinators, pollination and food production has been carried out by experts from all regions of the world, who have analysed a large body of knowledge, including about 3,000 scientific publications. It represents the state of our knowledge on this issue. This report concludes that pollinators, which are economically and socially important, are increasingly under threat from human activities, including climate change, with observed decreases in the abundance and diversity of wild pollinators. However, the report also outlines a wide range of management and response options that are available to halt the further decline of pollinators. The assessment concludes that 75% of our food crops and nearly 90% of wild flowering plants depend at least to some extent on animal pollination and that a high diversity of wild pollinators is critical to pollination even when managed bees are present in high numbers. IPBES was founded four years ago with 124 member nations to form a crucial intersection between international scientific understanding and public policy making.
A growing number of pollinator species worldwide are being driven toward extinction by diverse pressures, many of them human-made, threatening millions of livelihoods and hundreds of billions of dollars worth of food supplies, according to the first global assessment of pollinators.
However, the assessment, a two-year study conducted by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), also highlights a number of ways to effectively safeguard pollinator populations.
The assessment, titled Thematic Assessment of Pollinators, Pollination and Food Production and the first ever issued by IPBES, is a groundbreaking effort to better understand and manage a critical element of the global ecosystem. It is also the first assessment of its kind that is based on the available knowledge from science and indigenous and local knowledge systems.
Report by the Centre for Ecology and Hydrology(CEH), published in the journal Science on 29 June 2017.
CEH researchers designed and oversaw the delivery of this trial, with all aspects of the project scrutinised by an independent Scientific Advisory Committee, chaired by Prof Bill Sutherland of Cambridge University. This work aligns with NERC and CEH’s scientific aim of monitoring the impacts of human actions on the environment.
IFPRI's 2017 Global Food Policy Report provides analysis of major global and country-level food policy developments across the developing world. With rapid urbanization dramatically shifting demographics in recent years, this year’s report focuses on how urbanization is changing food systems, nutrition, and development. The report finds that growing cities provide opportunities to boost farmers' incomes and give urban poor more diverse and nutrition food supplies, if the two areas are effectively connected through strong value chains.
Wild and managed pollinators provide a wide range of benefits to society in terms of contributions to food security, farmer and beekeeper livelihoods, social and cultural values, as well as the maintenance of wider biodiversity and ecosystem stability. Pollinators face numerous threats, including changes in land-use and management intensity, climate change, pesticides and genetically modified crops, pollinator management and pathogens, and invasive alien species. There are well-documented declines in some wild and managed pollinators in several regions of the world. However, many effective policy and management responses can be implemented to safeguard pollinators and sustain pollination services.
