“…Wildlife crime represents a major threat to global biodiversity 1 – 4 . Many protected vertebrates, invertebrates and plants are targets for illegal activities when they have economic value 5 – 7 or when they are perceived to threaten livelihoods 8 – 10 . The effects of such activities can be profound 2 , 6 .…”

Patterns of satellite tagged hen harrier disappearances suggest widespread illegal killing on British grouse moors

Identifying patterns of wildlife crime is a major conservation challenge. Here, we test whether deaths or disappearances of a protected species, the hen harrier, are associated with grouse moors, which are areas managed for the production of red grouse for recreational shooting. Using data from 58 satellite tracked hen harriers, we show high rates of unexpected tag failure and low first year survival compared to other harrier populations. The likelihood of harriers dying or disappearing increased as their use of grouse moors increased. Similarly, at the landscape scale, satellite fixes from the last week of life were distributed disproportionately on grouse moors in comparison to the overall use of such areas. This pattern was also apparent in protected areas in northern England. We conclude that hen harriers in Britain suffer elevated levels of mortality on grouse moors, which is most likely the result of illegal killing.

“…However, the works of Booker et al (2012), Petersen et al (2015) and Volenzo and Odiyo (2020) found two main aspects of the supply chain of medicinal plants, a description of types of value chains and a description of the different supporting activities such as transports and storage, which are missing in studies conducted in Tanzania.…”

PurposeProducts of medicinal plants play significant roles in management of diseases. Their accessibility through trade plays a key role in health, economic and livelihood improvement. However, the traceability of the production process from their source in Tanzania is lacking. This study aims to depicture the production process of formulated products of medicinal plants.Design/methodology/approachThe study applied the value chain theory using qualitative data from literature review and survey to practitioners of traditional medicine. Survey data were collected through 15 in-depth interviews and ten focus group discussions in five regions of Tanzania.FindingsInput to output structure is performed through a five actors' value chain. The raw material is provided by harvesters who collected medicinal plants from wild. The processing is conducted by wholesalers and formulators. The wholesalers add value by drying, milling and bulk packaging of individual medicinal plants. Formulators mix different medicinal plants to create readymade products for specified diseases. Distribution is done by retailers and healers. There were six regulating and two supporting organizations. Private supporters were millers and transporters. Governance structure was deduced to be relational. Relational governance was a result of lack official standards along the value chain.Originality/valueThe described value chain can be used to guide investments in production of products of medicinal plants by improving formulation technology.

“…Previous studies have added and refined the initial process of VCA (Figure 1, Steps 1, 3 and 4) by adding consumer research to reflect the focus on consumer needs and wants (Collins and Dunne, 2008; Soosay et al , 2012). The approach of VCA was broadened and established as a research methodology by Hines and Rich (1997) and has been further developed and extended to a variety of situations (Jones and Womack, 1992; Rother and Shook, 1999; Petersen et al , 2014). Research has also been conducted on the “value” aspect of the VCA process (Babin and James, 2009; Manning, 2015).…”

Purpose Value Chain Analysis (VCA) is established as a diagnostic tool. The purpose of this study is to extend existing applications and develop an iterative and relational method. to facilitate the application of VCA to agri-food chains as a strategic process rather than a diagnostic tool. Design/methodology/approach Using a multiple case study design, the new approach to VCA was applied to four Australian prawn fisheries. These fisheries varied in size, location, management structures and marketing arrangements and allowed the general applicability of the approach to be explored. Findings The application of the revised VCA revealed the importance of undertaking a strategic approach, with the outcome for all fisheries being a greater understanding of their consumers and an enhanced realisation of commercial opportunities. Two fisheries completed the revised VCA, and the findings show that a relational approach is crucial in creating value. In addition, it was shown that formalised structures and the informal behaviours of the value chain members have a strong positive impact on the relationship process. Research limitations/implications The research furthers the value chain literature and contributes an iterative approach to the application of VCA. The research also shows that obtaining improvements is not achievable for all chains, and, if the entire chain is not engaged with the process, the value of the results will be compromised. Further research is needed to confirm the validity of findings in other food industries. Originality/value The relational approach is an original contribution to the area of VCA research and provides industry with a blueprint for creating successful value chains. Specifically, the areas of implementation and evaluation make an original contribution to the theoretical and practical knowledge of value chains.
