Development of a Tool for Navigating the Evidence concerning Land Managers and Woodland Creation in the United Kingdom

Woodland creation has become an important objective for a variety of stakeholders to help tackle the climate and biodiversity crises. One of the key evidence needs is a better understanding of the multiple factors influencing the willingness and ability of landowners and managers to establish new woodlands. To address this gap, a systematic map of evidence was prepared comprising publications from academic journals and grey literature accessed through bibliographic databases (Web of Science, Scopus, and CAB Abstracts), libraries, direct requests to relevant organisations and individuals, and citation tracking from past reviews. A screening process refined the evidence base to 226 studies within the UK. The systematic evidence map codes the content of each study against a comprehensive list comprising actors, drivers of or barriers to woodland creation, and outcomes. These are presented as a freely accessible, interactive online dashboard detailing sources of evidence. The systematic evidence map helps users navigate the evidence, demonstrating where the bulk of the evidence lies and, conversely, several evidence gaps where there is comparatively little evidence. The findings serve as a basis for dialogue with stakeholders to determine priorities for future primary research

What Is the Evidence Base Linking Gender with Access to Forests and Use of Forest Resources for Food Security in Low- and Middle-Income Countries? A Systematic Evidence Map

In nearly all parts of the world, an important part of people's livelihood is derived from natural resources. Gender is considered one of the most important determinants of access and control over forests. It is thought that women and men within households and communities have different opportunities and different roles and responsibilities in relation to forest use. It is probable that when women have equal access to forests, better food security outcomes can be achieved for individuals and households that are dependent on forests for their livelihoods. A systematic evidence map of the evidence base linking gender with access to forests and use of forest resources for food security was undertaken. Ten bibliographic databases and 22 websites of international development and conservation organisations were searched using keywords suggested by stakeholders. Other articles were found by emailing authors and organisations to send potentially relevant publications. 19,500 articles were retrieved from bibliographic databases and 1281 from other sources. After iterative screening, 77 studies were included: 41 focussed on Africa, 22 on Asia, 12 on Latin America, 2 were global. Most indicators of food security measure access to food, measured by total consumption, expenditure, or income. Studies showed strong gender specialisation: commercial access and utilisation of forests and forest products dominated by men, whereas access for subsistence and household consumption is almost exclusively the task of women. Despite the large number of studies reviewed, limitations of the evidence base, including methodological heterogeneity, a dominance of case studies as the study design, and unequal geographical representation in study locations, make it difficult to generalise about the overall importance of gender and its effect on access to and use of forests for food security in developing countries. The critical gaps in the evidence base include geographical representation in primary research and a greater breadth of study designs to assess gender implications of access to forest resources globally

State of forest research in 2010s – a bibliographic study with special reference to Finland, Sweden and Austria

Using bibliometric methods, this report analysed the volumes of global forest research and research collaboration between researchers, institutes and countries during the period 2010–2019. The keywords used in the bibliometric search resulted in a good match with the publication lists of three major Finnish forest research organisations. The final corpus of “forest” publications consisted of 355,000 articles, proceeding papers, reviews, books, book chapters and letters listed in the Web of Science database. During 2010–2019, the volume of Finnish publications in forest sciences have increased and the share of internationally collaborative papers has also grown. However, the international position of Finnish and Nordic forest research is slowly declining, owing to the modest growth in publishing, compared to fast-growing countries like China and Russia. When comparing Finnish and Swedish research organisations, those from Sweden were more internationally oriented. In both countries, the five top institutes produced more than three quarters of their country’s respective publications. Analyses based on bibliometric data used in this study reveal the status regarding publication output and trends. These analyses can provide objective evidence that is needed when developing research strategies and policies as well as allocating funding resources

Is local best? Examining the evidence for local adaptation in trees and its scale

Background: Although the importance of using local provenance planting stock for woodland production, habitat conservation and restoration remains contentious, the concept is easy to understand, attractive and easy to ‘sell’. With limited information about the extent and scale of adaptive variation in native trees, discussion about suitable seed sources often emphasises “local” in a very narrow sense or within political boundaries, rather than being based on sound evidence of the scale over which adaptation occurs. Concerns exist over the actual scale (magnitude and spatial scale) of adaptation in trees and the relative dangers of incorrect seed source or restricted seed collection, leading to the establishment of trees with restricted genetic diversity and limited adaptive potential. Tree provenance and progeny field trials in many parts of the world have shown the existence of genotype by environment interaction in many tree species, but have not necessarily looked at whether this is expressed as a home site advantage (i.e. whether provenance performance is unstable across sites, and there is better performance of a local seed source). Methods/design: This review will examine the evidence for local adaptation and its scale in a number of native tree species from different trial sites across the globe (e.g. tropical, Mediterranean, temperate). These trials have been measured and in some cases results published in a range of formats. The data have, however, usually been presented in the form of which provenances grow best at which sites. The review will examine existing data (published and unpublished) in the context of the scale of local adaptation, with the results being presented in two formats: (a) relating survival, performance of provenances (classified by seed zone/provenance region of origin) to seed zone/provenance region of the planting site; (b) plotting survival, performance provenances against the distance (Euclidean/ecological) between the provenance and the trial site.EEA BarilocheFil: Boshier, David.

What do we know about the impacts of the Marine Stewardship Council seafood ecolabelling program? A systematic map

Abstract Background Voluntary Sustainability Standards and ecolabels are market-based mechanisms used to encourage producers and consumers toward environmental sustainability. The Marine Stewardship Council (MSC) aims to improve ocean health and promote a sustainable seafood market. There is growing interest in the program’s impacts (direct and indirect) from changes to fisheries management and consumer awareness to market access and the reputation of fisheries. To better understand what is known about the program’s impacts and the quality of evidence available, this map collates and describes articles on the environmental, social, institutional and economic effects of the MSC, identifying the methods used to determine impacts, and highlighting knowledge gaps and clusters. Methods Following an a priori protocol, systematic searches of peer-reviewed literature were conducted in Web of Science, SCOPUS and AGRIS. Grey literature was gathered from Google Scholar, Microsoft Academic, and three subject-specific websites. A total of 771 articles were retrieved, 271 of which were screened at full-text. 28 articles met all inclusion criteria and a further 37 met all the criteria but did not have a comparator. Additionally, 108 articles that describe the MSC but do not investigate its impacts (thus failing on ‘comparator’ and ‘outcome’ inclusion criteria) were included in the narrative report. This provides an overview of MSC topics that are of general interest to researchers in comparison to articles that investigate MSC’s impact. Results Evidence of the impact of MSC certification fall in the following topic categories: economic (38%), environmental (25%), governance (29%) and social (8%). These articles documented diverse outcomes related to MSC certification. The most common are price premiums, market access, changes in stock health, ecosystem impacts and fisheries management changes. A key knowledge gap are articles on the effects of the MSC’s Chain of Custody Standard and its effects on the supply chain. Generally, literature focused on European and North American fisheries with little focus on fisheries situated in lower-income countries. Conclusions Research interest in the MSC has grown over the last two decades, however, little research uses study designs and evidence that can robustly detect or attribute change to the MSC. Greater focus on conducting robust quasi-experimental designs would help to better understand the program effects. Comparing areas of interest in the general literature (which, for example, shows greater focus on the governance aspects of the programme than found in literature using comparators) suggests that this is partly due to lack of resources, data access and the challenge of obtaining counterfactuals. Nevertheless, some topics were absent in all areas, such as the social and economic dynamics that link harvesters and supply chain actors. It is important to fill the identified knowledge gaps as the behaviours of certified harvesters, supply chain actors and other stakeholders are the key through which the public influence sustainability, market inclusion/exclusion operates, and inequality is generated. Understanding these processes can have wider relevance in the field, informing the design of other sustainability interventions
