Barriers to evidence use for sustainability: Insights from pesticide policy and practice.
Calls for supporting sustainability through more and better research rest on an incomplete understanding of scientific evidence use. We argue that a variety of barriers to a transformative impact of evidence arises from diverse actor motivations within different stages of evidence use. We abductively specify this variety in policy and practice arenas for three actor motivations (truth-seeking, sense-making, and utility-maximizing) and five stages (evidence production, uptake, influence on decisions, effects on sustainability outcomes, and feedback from outcome evaluations). Our interdisciplinary synthesis focuses on the sustainability challenge of reducing environmental and human health risks of agricultural pesticides. It identifies barriers resulting from (1) truth-seekers' desire to reduce uncertainty that is complicated by evidence gaps, (2) sense-makers' evidence needs that differ from the type of evidence available, and (3) utility-maximizers' interests that guide strategic evidence use. We outline context-specific research-policy-practice measures to increase evidence use for sustainable transformation in pesticides and beyond
Economics and Policy of Pesticide Reductions in Perennial Crops: The Role of Information within the Supply Chain
Short supply chains and the adoption of fungusâresistant grapevine varieties
Using fungus-resistant grapevine varieties can reduce pesticide use substantially, while maintaining production quantity and quality. Using survey data from 775 producers in Switzerland, we investigate the adoption of fungus-resistant varieties and especially analyze the relevance of marketing channels and short supply chains. We find that 20.1% of respondents use fungus-resistant varieties but the acreage is only 1.2%. Our results narrow down to a simple conclusion: the less distant the producer is from the final consumer, the more likely they use fungus-resistant varieties. For example, producers selling their wine mainly via direct marketing have a higher (8%â38%) uptake of fungus-resistant varieties
Data on Swiss grapevine growersâ production, pest management and risk management decisions
We present survey data from 436 grapevine growers across Switzerland and their production, pest, and risk management decisions. The online survey was conducted in spring 2022 in the three main official languages in Switzerland (German, French, Italian). The survey was used to obtain information on variety choice and farm management strategies, as well as farmer, farm, and spatial environmental characteristics. Moreover, we collected information around fungus-resistant grapevine varieties such as knowledge, attitudes, and perceptions of these varieties. We also elicited the current cultivation and growersâ intentions on future acreage under these varieties. In addition, data were collected on growersâ pest management strategies against weeds, insects, and fungi. Characteristics of the farm manager collected include education, farming goals, wine-related expertise, and information sources used. Information about the farm consist of marketing channels, labels, direct payment schemes, production systems and pesticide application machinery, among other details. Moreover, risk and time preferences, self-efficacy and locus of control were collected via self-assessed scales. The survey data were matched with spatial climatic data on municipality level (e.g. on temperature, precipitation, the number of yearly hail days, average sunshine duration and relative humidity) as well as pest pressure (e.g. infection risk by Oidium and Peronospora viticola) at weather station level.ISSN:2352-340
Farm-level data on production systems, farmer- and farm characteristics of apple growers in Switzerland
We here present survey data from apple growers across Switzerland. Data from 245 apple growers was collected, using an online survey in French and German in 2022. The sampled growers represent 24.4% from total land under apples. Apple production is one of the most economically relevant and pesticide intensive crops. Hence, the focus of the survey is on growersâ pest management decisions and marketing strategies. Survey data contains details on growersâ agronomic practices such as grown cultivars, pest management against fungi, insects, and weeds, as well as pesticide use for cosmetic purposes. Moreover, we collected information on pest management after harvest, i.e. storage loss strategies. Marketing characteristics include the sales channel chosen as well as labels used and contract arrangements with buyers. Moreover, detailed data about farm management strategies, behavioral factors, as well as other farm- and farmer characteristics was collected. Survey data is matched with a rich set of environmental data, i.e. precipitation, temperature, and apple scab infection risk.ISSN:2352-340
Nudging farmers towards low-pesticide practices: Evidence from a randomized experiment in viticulture
Planting fungus-resistant grapevines is an effective way to reduce pesticide use in grapevine production, but their uptake remains low. We explore whether providing personalized or general information on growersâ use of environmentally toxic fungicides changes their planting intentions of fungus-resistant varieties (i.e. salience nudging), conducting a randomized experiment with 436 grapevine growers in Switzerland. We find no effect of providing personalized or general information on the intended plantation share of fungus-resistant varieties. However, exploratory analyses suggest that growers' perceptions about fungus-resistant varieties may cause the null result, with growers having non-compliant environmental perceptions being particularly prone to boomerang effects.ISSN:2769-248
Ukraineâs path to European Union membership and its long-term implications. Bruegel Policy Brief Issue 05/24, March 2024.
Whether and when Ukraine accedes to the European Union will depend greatly on how and when its war with Russia ends and post-war reconstruction starts, and how the EU handles issues of governance, security, migration, trade, investment, the energy transition, decarbonisation and the EU budget.
The enlargement process is likely to overlap with post-war reconstruction, increasing the EU's influence in fostering Ukraineâs institutional development. Ukrainian leaders will have strong incentives to comply with the accession criteria, which the EU should use astutely to create a better-functioning economy and public institutions, especially by reducing opportunities for corruption. This will require clearer standards for rule-of-law and fundamental values, including effective tools to ensure continued compliance after accession. That is also the most effective way to ensure a positive impact of future enlargements on EU governance.
The EU will also need to develop assistance programmes to help the Ukrainian government manage post-war external and internal security challenges, including the large number of weapons in circulation, and to encourage Ukrainian refugees to return to the country when possible, as they will be needed for the reconstruction effort.
If the current EU budget rules were applied and there were no transitional arrangements â which is unlikely â we calculate the total annual cost of Ukraine's integration into the EU budget at 0.13 per cent of EU GDP, which would hardly change net recipient/payer positions of current EU members. Some of this funding would come back to the EU via EU companies participating in EU-funded projects in Ukraine. Ukraineâs entry into the EU would benefit EU GDP via trade, migration and foreign direct investment, boosting employment, production and tax revenues in the EU.
The history of EU enlargement shows that the strongest motivation for difficult reforms is a credible and predictable accession process based on rewarding reforms. Both Ukraine and the EU would benefit from progressive integration of the country into EU policies, alongside the formal accession negotiations. That would show the Ukrainian public the tangible benefits of moving towards EU standards, while also bringing Ukraine into areas such as energy cooperation and decarbonisation
