FOOD SYST. 27/09/19 Organic Farming Provides Reliable Environmental Benefits but Increases Variability in Crop Yields: A Global Meta-Analysis. Introduction Organic agriculture is an ecologically intensive production system expanding worldwide as demand for sustainability increases (Eyhorn et al., 2019; Willer et al., 2019).

FRONT. SUSTAIN. FOOD SYST. 27/09/19 Organic Farming Provides Reliable Environmental Benefits but Increases Variability in Crop Yields: A Global Meta-Analysis

Although organic farms produce lower yields than comparable conventional farms (Seufert et al., 2012; Ponisio et al., 2015), they are more profitable, more friendly to pollinators and the environment, and deliver equally or more nutritious foods with fewer pesticide residues (Kennedy et al., 2013; Tuck et al., 2014; Reganold and Wachter, 2016; Kovács-Hostyánszki et al., 2017; Seufert and Ramankutty, 2017). Not taking variability of sustainability metrics into account when comparing production systems is a key knowledge gap. Producers depend on reliable provisioning of yields, profits, and environmental services to ensure production system sustainability over time. Figure 1. Methods Data Generation. NATURE - 2018 - A global meta-analysis of yield stability in organic and conservation agriculture. Data generation We used two datasets: (1) a dataset on organic farming by Ponisio et al.21 comparing the yields of organic and conventional farming and (2) a dataset on no-tillage by Pittelkow et al.12 comparing the yields of no-tillage and conventional tillage.

Both datasets were generated for meta-analysis studies, comprising data from published experiments, and were published as supplemental material. Only field experiments containing side-by-side yield comparisons were included in the database to ensure comparability of the cropping system treatments. Because the focus of this study was on temporal yield stability, i.e., annual variability across years, single year comparisons from the original datasets were combined in order to create observations that were based on several years for each crop investigated (i.e., multiple year observations (MYO)).

Abstract Background Selection of pesticides with small ecological footprints is a key factor in developing sustainable agricultural systems.

PLOS 22/06/10 Choosing Organic Pesticides over Synthetic Pesticides May Not Effectively Mitigate Environmental Risk in Soybeans

Policy guiding the selection of pesticides often emphasizes natural products and organic-certified pesticides to increase sustainability, because of the prevailing public opinion that natural products are uniformly safer, and thus more environmentally friendly, than synthetic chemicals. Methodology/Principal Findings We report the results of a study examining the environmental impact of several new synthetic and certified organic insecticides under consideration as reduced-risk insecticides for soybean aphid (Aphis glycines) control, using established and novel methodologies to directly quantify pesticide impact in terms of biocontrol services. Conclusions/Significance These data bring into caution the widely held assumption that organic pesticides are more environmentally benign than synthetic ones.

Editor: Stephen J. Copyright: © 2010 Bahlai et al. NATURE 14/11/17 Strategies for feeding the world more sustainably with organic agriculture. General description of the SOL-model The SOL-model26 is a bottom-up, mass-flow model of the agricultural production and food sector.

NATURE 14/11/17 Strategies for feeding the world more sustainably with organic agriculture

It is calibrated with FAOSTAT data37, in particular the food balance sheets38, and covers all countries and geographic territories as well as commodities covered in FAOSTAT. Given lack of data for a range of those, this amounts to detailed coverage of 180 primary crop and 22 primary livestock activities in 192 countries. Behind this, data on commodity trees from FAOSTAT are used, covering around 700 intermediate products. In the following, only the main aspects and general traits of the SOL-model are presented, as a detailed description is already available elsewhere26.

Each crop and livestock activity in the SOL-model is characterized by a set of inputs and outputs, i.e. all physical flows of quantities and nutrients related to the individual activities.

An international team of experts led by Newcastle University has shown that organic crops are up to 60% higher in a number of key antioxidants than conventionally-grown ones.

NEWCASTLE UNIVERSITY 11/07/14 Organic vs non-organic food

Analysing 343 studies into the compositional differences between organic and conventional crops, the team found that a switch to eating organic fruit, vegetable and cereals – and food made from them – would provide additional antioxidants equivalent to eating between 1-2 extra portions of fruit and vegetables a day. The study, published today in the prestigious British Journal of Nutrition, also shows significantly lower levels of toxic heavy metals in organic crops. Cadmium, which is one of only three metal contaminants along with lead and mercury for which the European Commission has set maximum permitted contamination levels in food, was found to be almost 50% lower in organic crops than conventionally-grown ones.

INTECH 05/01/12 Organic Food and Agriculture - New Trends and Developments in the Social Sciences

This global survey of the organic food and farming considers how the social sciences have come to understand in what way consumers make their choices as they shop, and how new national markets evolve. It also surveys how established organic sectors in North America and Europe are changing in response to the changes, that in part, the organic movement has created. Moving from a wide range of social science disciplines, methodologies and perspectives, this book represents an excellent starting place for new readers, and offers innovation to those already familiar with the literature.

Plus d’une centaine d’agriculteurs et de techniciens, à laquelle il faut ajouter presque autant d’étudiants, ont assisté aux interventions et aux démonstrations de matériels. La manifestation doit également son succès à l’image professionnelle de l’agriculture bio qu’elle véhicule. Point de place pour des babas cool armés de binettes!
