Abstract Cellulosic biofuels from non-food feedstocks, while appealing, continue to encounter uncertainty about their induced land use change (ILUC) effects, net greenhouse gas (GHG) saving potential and their economic costs. We analyse the implications of multiple uncertainties along the biofuel supply chain from feedstock yields, land availability for production to conversion to fuel in the refinery on these outcomes. We find that compared to corn ethanol, cellulosic biofuels have a substantially smaller and less uncertain ILUC-related GHG intensity and lead to larger GHG savings at lower welfare costs of abatement, indicating the potential to make robust and substantial contributions to cost-effective climate change mitigation.

Abstract Using a hybrid multi-regional input–output approach, we traced sustainability footprints of a nutrient recovery strategy from sewage sludge applied in Italy. We then compared the results with the most common landfilling practice. Overall, accounting for indirect global upstream effects, using sewage sludge for organic fertiliser production generates more jobs and reduces more greenhouse gas emissions than landfilling. By contrast, landfilling stimulates the whole economy more, generating higher indirect turnover and reduces energy carrier use more. Finally, we accounted for uncertainties in these results using an error propagation method based on Monte Carlo simulations.

This study compares a real choice experiment (RCE) with three commonly used experimental auction (EA) mechanisms (Becker–DeGroot–Marschak, random nth price auction (RNPA), second price auction (SPA)) to determine whether willingness to pay (WTP) estimates differ across these elicitation methods. We use quality labels on eggs as the empirical application and find that the SPA, RNPA and RCE yield similar WTP estimates, while the BDM mechanism generally produces higher WTP estimates. We also compare these EAs and the RCE in an induced value setting and find that the BDM auction produces greater deviations from the underlying value than the other EAs and RCE. We suggest that RCEs may be preferable to BDMs for collecting WTP estimates in logistically difficult experimental settings.

This paper analyses data from a novel collective agri-environmental scheme (cAES) in Alsace, France, designed to protect the local European hamster population by motivating farmers to engage in habitat conservation measures. In contrast to typical conservation contracts that pay individual farmers based on their own performance, the cAES studied here pays farmers only when the percentage of land conserved by all farmers within a collective zone reaches a critical threshold. We find that the likelihood of participation is higher for farmers with a relatively large agricultural surface within the collective zone, increases with the number of farmers in a collective zone, and increases over time. Those with more land in the collective zone allocate more acreage to conservation. We define different contributor types and provide insight into the possible motives underlying contributions to collective conservation schemes.

Abstract Consumers and policymakers are increasingly concerned with environmental sustainability in food production. Yet rates of adoption of many conservation practices vary and are generally low. Existing instruments for practice adoption increase farmers’ expected net benefits from sustainable practices but do not manage associated risks which may be critical to risk-averse farmers. We build a model to characterize practice adoption by risk-averse farmers given practice-driven, long-run yield dynamics under various instruments, including price premiums, lump-sum subsidies and green insurance. We find rich scale and compositional effects that differ across instruments and that green insurance is significantly more cost-effective under plausible conditions.

Abstract This study explores the effectiveness of international efforts to build the capacities of national agricultural research and extension systems (NARES) in Africa and proposes actions to improve the performance of these systems. Analysis draws on agricultural research expenditure data in Africa, Asia and Latin America and key informant interviews of 26 senior representatives of international and African research organisations. We conclude that donors and international partners have increased the supply of professional African scientists while contributing relatively little to the institutional capacities of African NARES. We propose a transition to what we call a twenty-first century African-led agricultural research system and identify actions to manifest it.

Animal welfare is a credence attribute with public good characteristics. Using a discrete choice experiment, consumers’ willingness to pay (WTP) for a concretely planned state animal welfare label is derived and compared by product group (fresh vs. processed meat) and tax scenario (no tax vs. additional animal welfare tax included in price). Consumers have a positive WTP for the state label. However, label WTP is significantly lower for processed than for fresh meat. An additional tax does not impact label WTP on average. Results provide insights for both policymakers on label implementation and farmers on further investments in animal welfare.
