Narratives of land abandonment in a biocultural landscape of Spain
No full textRural abandonment is a significant process in the Mediterranean region, posing sustainability challenges for rural and urban areas. Although there is an increase in studies focusing on the ecological implications and impacts of land abandonment and the role of rewilding, there is a knowledge gap in the study of the socio-cultural dimension of abandonment from the local perspective, even though it is crucial for land management decision. This study focuses on a case study in Western Spain, where a social survey was used to assess the perceptions of local communities regarding land abandonment and their implication on nature’s contributions to people and quality of life. A survey campaign was administered in the case study region during the summer of 2020, collecting 205 face-to-face surveys. The results show that local communities overall have a negative reaction toward rural abandonment. In addition, local respondents recognize how traditional agriculture is the main source for maintaining nature’s contributions to human well-being. Additionally, four groups of narratives toward rural abandonment were identified representing clusters of respondents with different motivations and interpretations of rural abandonment. This paper calls for understanding better the perceptions, values, and motivations toward rural abandonment and how their outcomes can be used as input for landscape management. Our results indicate that the local population perceives that the loss of rural livelihoods may entail serious environmental and societal problems, as locals are forced to abandon their rural-associated ways of life and migrate to urban areas.</p
Diverging values and development options for agroforestry in a metropolitan area of North Africa
No full textThe use of large green infrastructures in peri-urban areas, such as urban forests, has become one of the most relevant tools to mitigate some of the negative impacts of urbanization while providing multiple benefits to city dwellers. However, these peri-urban forests are often highly contested spaces. Agroforestry offers a promising solution to reconcile diverging interests in the peri-urban context. In this study, we look at the Maâmora cork oak forest in Morocco, which exemplifies some of the challenges faced by large-scale green infrastructures that become enmeshed in rapid urbanization. We explore these dynamics and (1) map how local residents perceive a peri-urban agroforest, (2) characterize groups of residents according to their perceptions, and (3) disentangle preferences for the development of green infrastructure. To do this, we conducted 278 participatory mapping interviews in three urban and three rural settlements around Maâmora, mapping urban and rural residents’ uses, values, disvalues, and development preferences. Our results show how urban agroforestry could reconcile multiple demands in peri-urban green spaces. However, our analysis reveals contrasting development preferences between rural and urban residents and points to a growing disconnection from nature among urban dwellers, which risks marginalizing diverse perspectives from those residents more closely connected to the landscape. Our analysis also highlights the importance of exploring disvalues for a better recognition of the plural values of nature and to identify potential conflicts in the context of urban and rural planning.</p

No full textEcological and social outcomes of urbanization on regional farming systems: a global synthesis
No full textThough urban land covers only around 0.5% of the Earth’s terrestrial surface, urbanization often leads to significant changes in land use and land cover. However, knowledge on the ecological and social outcomes of urbanization is largely fragmented across a multitude of local-level studies. We synthesized the outcomes of urbanization on 15 ecological and social variables associated with regional farming systems, namely water quality, agro-biodiversity, carbon sequestration, control of invasive species, soil fertility, control of soil erosion, pollination, cultural identity, food security, income and employment, demographic stability, conflict mitigation, social network, health and education, and equity. From 246 cases, positive, negative, and non-conclusive urbanization outcomes were extracted. Additionally, distributions of these outcomes by continent, population size of towns/cities, national per-capita GDP, and dominant farming systems were assessed. As a result, more negative than positive outcomes were found. Although ecological outcomes were largely negative, social ones were mostly positive. Threats to water quality, demographic stability, and cultural identity arose as particularly pressing issues. The ecological outcomes related to pollination were largely positive but all other ecological variables reported higher negative outcomes. The social outcomes related to the economic viability of farming and employment were largely positive, whereas those related to cultural and equity aspects were predominantly negative. The ecological outcomes were frequently negative in the Global South, medium-large cities, poor countries, and for livestock or fishery systems. The social outcomes were more frequently negative in the Americas, highly populated cities and megacities, wealthy countries, and for livestock and fishery systems. The threats and opportunities of rural–urban transformations in different dimensions and contexts of farming systems should be considered in any urban planning strategy

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
