“…Transitioning from the potentially opaque measures used by the GCJV for habitat objectives and UMGLJV for threat of development to natural measures such as hectares of selected habitat types and rate of habitat conversion, respectively, could increase transparency and repeatability of the value model. Replacing the constructed categorical measures (i.e., High, Medium, Low) for social objectives (i.e., bird watching and waterfowl hunting opportunity) with empirical data such as hunting days afield or bird watching day-trips in the county could also improve model repeatability and transparency (Pickard 2015;Krainyk et al 2021).…”

The North American Wetlands Conservation Act (16 U.S.C. 4401-4412) provided funding and administration for wetland management and conservation projects. The North American Wetland Conservation Fund, enabled in 1989 with the Act, provides financial resources. Resource allocation decisions are based, in part, on regional experts, particularly migratory bird Joint Ventures (JVs) (i.e., partnerships for cooperative planning and coordinated management of the continent’s waterfowl populations and habitats). The JVs evaluate funding proposals submitted with their respective regions each year and make funding recommendations to decision makers. Proposal evaluation procedures differ among JVs, however, it could be helpful to consider a transparent, repeatable, and data-driven framework for prioritization within regions. We used structured decision making and linear additive value models for ranking proposals within JV regions. We used two JVs as case studies and constructed two different value models using JV-specific objectives and weights. The framework was developed through a collaborative process with JV staff and stakeholders. Models were written in Microsoft Excel. To test these models, we used six NAWCA proposals submitted to the Upper Mississippi / Great Lakes Joint Venture in 2016 and seven proposals submitted to the Gulf Coast Joint Venture in 2017. We compared proposal ranks assigned by the value model to ranks assigned by each JV’s management board. Ranks assigned by the value model differed from ranks assigned by the board for the Upper Mississippi / Great Lakes Joint Venture, but not for the Gulf Coast Joint Venture. However, ranks from the value model could change markedly with different objective weights and value functions. The weighted linear value model was beneficial for ranking NAWCA proposals because it allows JVs to treat the ranking as a multiple objective problem and tailor the ranking to their specific regional concerns. We believe a structured decision making approach could be adapted by JV staff to facilitate a systematic and transparent process for proposal ranking by their management boards.

“…We express the marginal value of nodes in terms of Δ DUD (DUD baseline − DUD knockout ) and Δ SURV (SURV baseline − SURV knockout ), such that a positive value represents a net positive contribution (i.e., marginal value) of a node and a negative value a negative contribution. SURV is important because of its effects on population dynamics and DUD is a useful metric because it is commonly used by waterfowl managers to quantify total duck use of an area through time (Krainyk et al., 2021).…”

Marginal value analysis reveals shifting importance of migration habitat for waterfowl under a changing climate

Migratory waterfowl are an important resource for consumptive and non‐consumptive users alike and provide tremendous economic value in North America. These birds rely on a complex matrix of public and private land for forage and roosting during migration and wintering periods, and substantial conservation effort focuses on increasing the amount and quality of target habitat. Yet, the value of habitat is a function not only of a site's resources but also of its geographic position and weather. To quantify this value, we used a continental‐scale energetics‐based model of daily dabbling duck movement to assess the marginal value of lands across the contiguous United States during the non‐breeding period (September to May). We examined effects of eliminating each habitat node (32 × 32 km) in both a particularly cold and a particularly warm winter, asking which nodes had the largest effect on survival. The marginal value of habitat nodes for migrating dabbling ducks was a function of forage and roosting habitat but, more importantly, of geography (especially latitude and region). Irrespective of weather, nodes in the Southeast, central East Coast, and California made the largest positive contributions to survival. Conversely, nodes in the Midwest, Northeast, Florida, and the Pacific Northwest had consistent negative effects. Effects (positive and negative) of more northerly nodes occurred in late fall or early spring when climate was often severe and was most variable. Importance and effects of many nodes varied considerably between a cold and a warm winter. Much of the Midwest and central Great Plains benefited duck survival in a warm winter, and projected future warming may improve the value of lands in these regions, including many National Wildlife Refuges, for migrating dabbling ducks. Our results highlight the geographic variability in habitat value, as well as shifts that may occur in these values due to climate change.

Purpose The growth of global food delivery (FD), which could reach a market value of 1510 billion dollars by 2027, could raise significant sustainability concerns, especially in terms of the social impact related to the expansion of the gig economy. This study, therefore, aims to analyze the social sustainability of the FD, taking Italy as a case study. The results could be a baseline to suggest practices that could promote a more socially responsible FD sector. Methods Social life cycle assessment (S-LCA) was used, following the guidelines of the Product Social Impact Life Cycle Assessment (PSILCA) and considering four categories of stakeholders (workers, value chain actors, society, and local community), 11 risk categories, and 13 subcategories, mainly based on both the availability of data and their adherence to the objectives of the study and FD. Results and discussion The main risks are associated with low wages, improper working hours, high accidentality, and approximation in food handling. Specifically, the wages of riders, 23% of whom are migrants, are just 14% above the poverty line in Italy and 67% below the median income. With 30-h work weeks, moreover, riders may face high risks of economic vulnerability. Stressful working conditions and the absence of mandatory protective equipment have resulted in 17 fatalities × 100,000 workers and 25 accidents × 1000 workers, which could generate a medium risk that violations of labor laws will occur. All this is also due to the low unionization in the Italian FD. Finally, results also show a flaw in food safety, as riders are not required to have HACCP and ATP attestation. Conclusions Italian legislation and the business models of FD companies are still shown to be insufficient to guarantee the fairness of protections for riders, which are substantiated by low wages, high accident rates, poor union rights, and improper working hours. In addition, doubts are raised about the hygiene of containers carrying food during transport, as they could induce a potential microbiological health risk for consumers, especially related to food handling during transport.
