Strategic Design of Public Food Procurement to Leverage Positive Food Systems Outcomes: A Framework of Actions

open access: yesSustainable Development, EarlyView.
ABSTRACT There is substantial potential for the procurement of food by public institutions to contribute to Sustainable Development across multiple environmental, social, and economic outcomes. In this study we used theories of policy instrumentation and learning to analyse global guidance for designing public food procurement instruments to leverage ...

Towards GMO-free landscapes? Identifying driving factors for the establishment of cooperative GMO-free zones in Germany [PDF]

open access: yes
Since the end of the quasi-moratorium on genetically modified organisms (GMO) in the European Union in 2004, the establishment of GMO-free zones has become an EU wide phenomenon.

Precision determination of the pi-N scattering lengths and the charged pi-NN coupling constant [PDF]

open access: yes, 1999
We critically evaluate the isovector GMO sumrule for the charged $\pi N N$ coupling constant using recent precision data from $\pi ^-$p and $\pi^-$d atoms and with careful attention to systematic errors. From the $\pi ^-$d scattering length we deduce the

Estimating Causal Effects With Observational Data: Guidelines for Agricultural and Applied Economists

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Consumer Benefits of Labels and Bans on GMO Foods: An Emprical Analysis Using Choice Experiments [PDF]

open access: yes
Applying a choice experiment on the choice of consumer goods we show that Swedish consumers do not regard GMO food as being equivalent to conventional food. A central argument by proponents of GMO is that the end products are identical to those where GMO

A Window of Opportunity for GMO Regulation: Achieving Food Integrity Through Cap-and-Trade Models from Climate Policy for GMO Regulation [PDF]

open access: yes, 2017
GMOs are the links of our centralized food system, largely dependent on international trade. GMOs are inherently unsustainable because they reduce biodiversity, harm the environment, and empower positive feedback loops between monocultures, industrial ...

Genetic engineering for SIT application: a fruit fly‐focused review

open access: yesInsect Science, EarlyView.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.

Pollen from genetically modified plants in honey – problems with quantification and proper labelling

open access: yesJournal of Apicultural Science, 2013
Maize can be a valuable source of pollen when plants attractive for bees are not available. Honeybees can forage from conventional maize as well as from genetically modified (GM ) maize.

Functional validation of a white pupae minimal gene construct in Ceratitis capitata (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
An intronless version of the white pupae (wp) gene was engineered to restore the wild type brown puparium color in white pupae phenotype mutants of the Mediterranean fruit fly, Ceratitis capitata. Functionality of the minimal gene version (mini‐wp) was verified in vivo, as one copy of mini‐wp successfully restored the wild type phenotype in homozygous ...
