ABSTRACT In land system science (LSS), the globalisation of land use is often understood via trade flows. Fewer studies have explored the power asymmetries and local resistance that shape global connections. Consequently, calls for a deeper engagement with power and agency have been made within LSS. To accommodate this, we engage the ethnographic literature on encounters, emphasising the concepts of resistance and friction. These capture the ways actors position themselves in global systems, resist, and create global connections. To illustrate its relevance for land systems, we use qualitative data from the mining sector of Tanzania, highlighting the emergence of resource nationalism as an alternative form of globalisation (alter-globalisation). We argue that a focus on resistance, friction and alter-globalisation can move LSS towards a deeper engagement with power and agency in global flows, revealing the competing actors, values and visions embedded in land systems.

ABSTRACT Local farmers’ engagement and contributions are increasingly underscored in resources restoration policy. Yet, empirical context-situated understanding of the environmental impacts of farmer-led restoration remains scant. Using six Agent-based Modeling (ABM) simulations that integrate multi-type data, we explore the potential spatial-temporal aggregate patterns and outcomes of local restoration actions in Central Malawi. Findings uncover a 10-year positive trend and spatially explicit potential restoration extent and intensity, greenness, and land productivity, all varying by farmer’s participation level. Landscape regreening is modestly promising with fluctuating greenness levels and low, slightly incremental, then steady land-productivity levels. Findings also show appropriate incentives, restoration knowledge, and inspiring local leadership as propitious management options for boosting local restoration. Bundling these enabling management and policy options would maximize local restoration. Findings suggest empowering bottom-up restoration efforts for enhanced environmental impacts. We also demonstrate the potential of using ABM to offer insights for spatially targeted, evidence-based restoration policy implementation and monitoring.

ABSTRACT Soil degradation creates diverse problems across varying dimensions, including food and water insecurity as well as greater vulnerability to climate change especially in Brazil. This uncover the complexity of land use as well as the challenges to asses it. In this article, a multiple case study is presented. Results obtained from three surveys using the IQRM method are discussed to assess the extent to which agricultural land is capable of supporting the uses and management adopted by farmers. When inferring about the degree of adequacy of land use and management, IQRM makes it possible to indicate situations that deserve greater attention because they demonstrate a need for improvements or because they represent references of good environmental performance in a given context. The method IQRM integrated different kinds of knowledge in land use assessment. It is a crucial factor to foster social learning processes and sustainability in the Brazilian context.

ABSTRACT This paper explores how the state-led ‘freshening the coastal zones’ policy has been implemented in pursuit of sustainable development in the Vietnamese Mekong Delta. Drawing on a case study of the Ba Lai irrigation scheme in a coastal district of Ben Tre Province, the paper argues that the state’s ideology of ‘freshwater over saltwater’ results in contested land-use policies that, in turn, drive forced transformation of resource-based livelihoods. By unraveling the political ecology of these social-political dynamics, the study shows how contemporary land-use approaches have modified coastalscapes, evidenced by the continued expansion of freshwater-based agricultural systems. These agriculture-favored development policies have negatively affected agrarian communities’ options to sustain their traditional livelihoods (e.g. shrimp farming), which otherwise help yield higher incomes. This paper raises doubts about the ‘freshening coastal zones’ policy in addressing saltwater intrusion at the delta scale, while recognizing the equal role of saltwater in supporting coastal livelihoods.

ABSTRACT This study employed Contingent Valuation and Discrete Choice Experiment methods to investigate the potential of a Payment for Ecosystem Service mechanism that incentivizes sustainable land use practices by determining the willingness of ecosystem service beneficiaries to pay for delivery of services via adoption of sustainable land use practices by upland poor, ethnic minority communities, and vice versa, the willingness of communities to adopt such practices upstream of Vu Gia river, central Vietnam. From the users’ side, 64% and 56% of pooled respondents said they are willing to pay a higher rate for water and electricity consumption, respectively, if upstream watershed management is improved. On the providers’ side, WTA was high if the conditionality is relaxed. Our findings suggest a fundamental challenge in designing PES that matches the needs of buyers and providers – a scheme that ensures ecosystem service flows but does not impose stringent rules that limit stakeholders’ participation.

Introduction We are delighted to present this collection of articles under the theme ‘Women in Land Science.’ The three guest editors and one editor in chief all decided to collate such an issue at a March 2021 virtual meeting of the journal’s editorial board when brainstorming ideas of current interest and timely need, for this journal to address. The Journal of Land Use Science was seen as a perfect location for such a special issue focus. The journal itself is a strong representation of excellence in the field as well as representation by gender as highlighted both in the journal co-editors and the editorial board composition. More specifically, the journal is co-edited by two lead scientists, Dr. Daniel Müller and Dr. Darla Munroe, one man and one woman. Of the 22 members of the editorial board, there are 12 men and 10 women serving in this role. The representation of female scientists in key research leadership positions is an important factor within the discourse on gender bias. In a recently published piece in AGU Advances (Ranganathan et al., 2021), the authors highlight the continuing persistence of inequality within academia in the geosciences. Their research finds that while 27% of faculty in academia in the US are women, this is not equal across ranks. More specifically, while 46% of assistant professors are female, this decreases to only 19% of full professors. The researchers did not have sufficient data to determine all the causes of such discrepancies especially related to higher attrition of female researchers; however, they do discuss other research that has pointed to higher female attrition linked to existing institutional cultures and policies such as very weak or inadequate childcare and maternity leave, a lack of protection from harassment, inadequate timelines to tenure, and existing cultures of sexism all leading to academic careers becoming inaccessible to women and other historically excluded groups. This article was part of a special issue in AGU Advances addressing ‘Diversity, Equity, and Inclusion in the Earth and Space Sciences.’ Thus, the current JLUS issue is timely in that we are also making space for these discussions, happening in many other fields across the social and natural sciences. According to UNESCO Institute for Statistics (UIS), less than 30% of the world’s researchers are women (uis.unesco.org 2021) and so the goal of this special issue is twofold. First, we wish to highlight some of the amazing research being conducted and led by female research scientists within the field of land-use science. In addition, we also wish to contribute to the necessary discussions on the challenges and possible deterrents for women researchers within these same fields. The fact that such an issue could also be the very first Open Access issue for the journal was extra motivation for us to put out a call and move papers through the submission, review, and revision process as quickly as possible.

我们很高兴以“妇女参与土地科学”为主题，介绍这一系列文章。三位客座编辑和一位主编都决定在2021年3月的期刊编辑委员会虚拟会议上整理这样一个问题，当时正在集思集想当前感兴趣和及时需要的想法，供期刊解决。《土地利用科学杂志》(Journal of Land Use Science)被认为是刊登这类特刊的最佳地点。该期刊本身是该领域优秀人才的有力代表，在期刊共同编辑和编辑委员会的组成中都突出了性别代表性。更具体地说，该杂志是由两位首席科学家Daniel m勒博士和Darla Munroe博士共同编辑的，他们是一男一女。在编辑委员会的22名成员中，有12名男性和10名女性担任这一角色。女性科学家在关键研究领导岗位上的代表性是性别偏见话语中的一个重要因素。在AGU Advances最近发表的一篇文章中(Ranganathan et al.， 2021)，作者强调了地球科学学术界持续存在的不平等。他们的研究发现，尽管美国学术界27%的教职员工是女性，但这一比例在各个层级之间并不平等。更具体地说，46%的助理教授是女性，而正教授中只有19%是女性。研究人员没有足够的数据来确定这种差异的所有原因，特别是与女性研究人员的高流失率有关;然而，他们确实讨论了其他一些研究，这些研究指出，女性的高流失率与现有的制度文化和政策有关，比如育儿和产假非常薄弱或不足，缺乏对骚扰的保护，获得终身职位的时间限制不足，以及现有的性别歧视文化，所有这些都导致女性和其他历史上被排斥的群体无法进入学术生涯。本文是AGU Advances关于“地球和空间科学中的多样性、公平性和包容性”特刊的一部分。“因此，当前的JLUS问题是及时的，因为我们也在为这些讨论提供空间，这些讨论发生在社会和自然科学的许多其他领域。”根据联合国教科文组织统计研究所(UIS)的数据，世界上不到30%的研究人员是女性(uis.unesco.org 2021)，因此这一期特刊的目标是双重的。首先，我们希望强调在土地利用科学领域内由女性研究科学家正在进行和领导的一些令人惊叹的研究。此外，我们还希望就这些领域的女性研究人员面临的挑战和可能的阻碍进行必要的讨论。事实上，这样的问题也可能是期刊的第一个开放获取问题，这是我们发出呼吁并尽快通过提交，审查和修订过程的额外动力。这证明了作者们在本期杂志上的热情和奉献精神，我们收到了如此丰富的学术贡献，这些贡献在科学上是重要的，及时的，并且可以共同为土地系统科学界在未来几年扩大和多样化的努力中制定一个雄心勃勃的议程。在下面的各节中，我们首先回顾我们在土地利用科学中与性别平等的经验和关系。然后，我们简要地总结了本期杂志的三个新兴主题:本期杂志中土地科学应用之间的一致性，土地中现存性别差距的轮廓。1,1 - 11 https://doi.org/10.1080/1747423X.2022.2022285

ABSTRACT Most of the peri-urban areas in European cities are characterized by a mix of rural and urban uses. Despite being sprawled areas, they provide opportunities for improving green connectivity at a multiscale level, between urban-green and natural or agricultural peripheral extensions. Several land monitoring services, both at national and European levels, have become key tools to perform the analysis and diagnosis of its transformation patterns and dynamics. However, the accuracy of available datasets is typically not adequate for approaching the spatial complexity of these areas. This research proposes a methodology to improve precision by combining land use datasets and applies it to a specific study case, the peri-urban Spanish Mediterranean Huertas, highly valued agricultural and cultural landscapes under an intense urban pressure. Findings reveal that this method detects and solves inaccuracies, and it is easily replicable in different spatial contexts, becoming an effective tool for decision-making processes.

ABSTRACT Sustainability certification has been posited as a key governance mechanism to enhance the climate resilience of smallholder farmers. Whilst many certifications now include climate resilience in their standards, their ability to deliver this for smallholders remains untested. We take the case of the 2015–16 drought-shock to cocoa production in Ghana to examine whether certification can enhance smallholder climate resilience. We used a novel transdisciplinary methodology combining participatory outcome definition with household surveys, biophysical measurements, satellite data and counterfactual analysis. Utilising our climate resilience framework, we find that certification has a strong effect on the adoption of basic management, e.g. fertilization, but a weak influence on more complex resilience strategies, e.g. agroforest diversification. Beyond certification, we identify strong regional patterns in resilience. These findings suggest that certification has some potential to enhance climate resilience but greater focus on facilitating diversification and adapting to sub-national contexts is required for improved effectiveness.

ABSTRACT Biological invasions are complex processes requiring coordinated and spatially targeted management. This study assessed spatiotemporal trajectories and determinants of Prosopis cover in Baringo County, Kenya. Land cover data for every seven years between 1988 and 2016 revealed the presence of Prosopis. We tested for trajectory clusters using spatial autocorrelation and overlaid the trajectory categories with landscape features. Generally, most plots were only temporarily managed or not managed at all, while continuous management of Prosopis occurred mainly near rivers and on plots suitable for cultivation. Parcels within 250 m from roads, which are dispersal pathways for Prosopis seeds, were rarely cleared of Prosopis. We conclude that successful management requires incentives for stakeholders’ engagement in collective management action at a landscape level. Trajectory mapping should be integrated into planning tools to foster the prioritization of timely and context-specific response mechanisms.

This study assessed spatiotemporal trajectories and determinants of Prosopis cover in Baringo County, Kenya. Land cover data for every seven years between 1988 and 2016 revealed the presence of Prosopis. We tested for trajectory clusters using spatial autocorrelation and overlaid the trajectory categories with landscape features. Generally, most plots were only temporarily managed or not managed at all, while continuous management of Prosopis occurred mainly near rivers and on plots suitable for cultivation. Parcels within 250 m from roads, which are dispersal pathways for Prosopis seeds, were rarely cleared of Prosopis. We conclude that successful management requires incentives for stakeholders’ engagement in collective management action at a landscape level. Trajectory mapping should be integrated into planning tools to foster the prioritization of timely and context-specific response mechanisms.","PeriodicalId":56005,"journal":{"name":"Journal of Land Use Science","volume":"17 1","pages":"487 - 504"},"PeriodicalIF":3.2,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47993972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT The fusion of optical imagery with radar data can provide more accurate land cover change analysis of deforestation and tree-based agriculture. Radar data is limited temporally with most geographic areas not covered prior to 2007. This paper presents a new methodology to classify land cover change related to oil palm expansion that takes historic data limitations into account. Our approach utilizes Hansen’s Global Forest Cover data, optical imagery, and texture information, to extract land cover information in Sumatra and Western Malaysia, where historical data is absent. Our method demonstrates how to accurately classify oil palm without radar data with overall accuracies for optical only experiments within 4.4% of optical plus radar classifications. Our results show agricultural land use was the primary driver of land cover change with the largest increase due to oil palm expansion (6.1%). Better estimations of oil palm expansion could be used in sustainable land management policies.
