“…Adaptation strategies should minimize harm from and exploit beneficial opportunities associated with climate change (Klein et al, 2014;Kurukulasuriya & Rosenthal, 2013). Many of these strategies are low-cost interventions; however, adoption of them may be slowed by uncertainty about their effectiveness, reluctance due to increased risk, the relative invisibility of productivity losses associated with soil loss, lack of concern for off-farm damages associated with highly erosive farming practices, and lack of knowledge about options (Barrowclough & Alwang, 2018). Some suggest that CA can help arrest soil degradation and increase long-term productivity (Barrera et al, 2019;Barrowclough et al, 2016;Delgado et al, 2019).…”

“…With respect to the soil management practices, deviation ditches were associated with large reductions in erosive soil loss, but tend to be prohibitively expensive for farmers to build. Contour plowing is relatively inexpensive, and we already see wide adoption of this practice (Barrowclough & Alwang, 2018).…”

The Andean region of Ecuador is dominated by small-scale agriculture on steep slopes vulnerable to erosion, soil degradation, and subsequent productivity loss. Soil erosion rates exceed the average rate of soil formation by 9-286 times, making current agricultural practices in the region unsustainable, and threatening to increase food insecurity. The projected effects of a changing climate vary across the Andean region, with higher precipitation and erosion rates projected for some areas. However, even in areas where the precipitation rates are expected to be lower, the projected erosion rates will still be unsustainable. Research on conservation agriculture (CA) practices conducted from 2008 to 2017 in the highlands of Ecuador suggests that yields and cost savings ultimately make several CA production systems profitable compared to conventional practices. In the very short term, large gains did not emerge, and the best that could be said about CA is that it did not reduce productivity. Over the medium term, improvements in soil health (lower erosion) led to higher profitability that made the practices more profitable than conventional practices over the entire rotation. However, adoption of these alternatives by local producers, even in research areas, is low. Lack of public or private agricultural extension contributes to slow diffusion of new technology and best management practices in the region. There is a need to develop improved communication with local farmers to more effectively relay how CA protects the soil, mitigates degradation, and provides a means to achieve food security and avoid a humanitarian crisis.

“…With respect to the fisheries sector, Bronnmann and Asche [ 12 ] examine preferences for sustainable fisheries comparing ecolabelled wild salmon with farmed salmon, Ropars-Collet et al [ 13 ] examine people’s preferences for the provision of amenities from the fishing sector along the coasts of the English Channel and the North Sea, and Paltriguera et al [ 14 ] evaluate people’s preferences for recreational attributes of a coastal Marine Protected Area in England. Within conservation, Barrowclough and Alwang [ 15 ] study farmers’ attitudes towards conservation agriculture in Ecuador, Brouwer et al [ 16 ] measure the non-market benefits of ecological river restoration, Fujino et al [ 17 ] study attitudes towards a Japanese biodiversity conservation policy and Dechasa et al [ 18 ] estimate the economic values of wetlands services. In a more general context, Huynh et al [ 19 ] explore new ways of understanding and measuring preferences for different remediation technologies for contaminated environment approaches in New South Wales, Australia and Seeteram et al [ 20 ] analyze the willingness to pay for restoration of ecosystem services in south Florida (US).…”

Modelling welfare estimates in discrete choice experiments for seaweed-based renewable energy

We explore what researchers can gain or lose by using three widely used models for the analysis of discrete choice experiment data—the random parameter logit (RPL) with correlated parameters, the RPL with uncorrelated parameters and the hybrid choice model. Specifically, we analyze three data sets focused on measuring preferences to support a renewable energy programme to grow seaweed for biogas production. In spite of the fact that all three models can converge to very similar median WTP values, they cannot be used indistinguishably. Each model is based on different assumptions, which should be tested before their use. The fact that standard sample sizes usually applied in environmental valuation are generally unable to capture the outcome differences between the models cannot be used as a justification for their indistinct application.

“…Their findings indicate substantial demand for river rehabilitation in developing world cities and that choice experiments can provide relevant information for land use planning. In addition, Barrowclough and Alwang (2017) investigated farmers' expectations regarding effects of a hypothetical set of conservation-oriented agricultural production practices on yields, labor use, erosion, and costs. Thus, DCEs have been extensively applied to address broad aspects of sustainable agricultural production in diverse settings abroad.…”

Appropriate environmentally friendly agricultural technologies and practices must be implemented in China (and many other countries) to reduce farmland non-point source pollution and meet sustainability objectives. A major hindrance to their implementation is that Chinese farmers have very low willingness to accept such practices. Discrete choice experiments (DCEs) have known value for identifying goods or policies with attractive attributes, and thus exploring target groups' choice behavior and addressing such problems. Sound questionnaire design is of paramount importance for robust results. This article describes the nature and theoretical foundations of DCEs and considers their use in diverse applications abroad, and their limited but growing applications in China. It then presents a case study, focused on the detailed design of DCEs intended to gauge paddy farmers' willingness to accept several agriculturally friendly techniques and related compensation methods, problems encountered, and predictions for future studies. KeywordsDiscrete choice experiments • Fractional factorial orthogonal design • Environmentally friendly agricultural technology • Agri-environmental policy design * Liang-guo Luo
