ABSTRACT Romanian farming is characterized by fragmented land, high age of operating farmers and low productivity that raises the question of barriers and necessities for consolidation, development and succession. This study explores the development trajectories of smallholder farming in the Romanian counties of Cluj and Maramureș using the concepts of embeddedness (as outlined in the framework of global production networks) and the resource-based view. It aims to understand the interplay of framework conditions with the way how smallholders mobilize different types of resources. Conceptually, the study shows that the resource-based view should be applied within wider contexts: Aspects of societal and network embeddedness (including prevalent mistrust, informality in governing land and misaligned regulative incentives) favour high reliance on family for resource mobilization and hinder consolidation, succession and innovation. While commonalities with post-socialist countries exist, several structural factors are unique to Romania.

ABSTRACT What are patterns of gender and authorship in urban land science? Our bibliometric analysis shows that the proportion of women shrinks among highly productive, impactful, and senior authors, akin to a pyramid shape. First, women are only one in ten researchers with an h-index above the 95th percentile. Second, women are first authors on 20% of all influential papers cited more than one hundred times. Third, women publish less frequently (1.6 papers/year) than men (2.2). Fourth, women have shorter career lengths (9.4 years) than men (11.8). Since the 2000s, citation rates for women and men have converged. For the generation starting careers since 2016, the proportion of women with an h-index above the 90th percentile increased to 25%. During the Covid-19 pandemic, there was a 51% increase in productivity for women. Despite these changes, gender disparities in urban land science are most pronounced among the most productive and impactful authors.

ABSTRACT Land cover and land use changes cause global environmental degradation yet changes in cover may have different impacts than changes in use. Here, we examine changes in land cover (rangeland conversion to vineyard) and land use (assocaited grazing loss on proximate rangelands) in Santa Barbara County, USA, between 1984 and 2019 paying attention to (1) instances where grazing was removed and (2) the effectiveness of local policies in keeping grazing active. We found that 13% of rangeland parcels converted to vineyards, and that 69% of these properties ceased grazing, even though 92% of the rangeland parcels in our analysis that converted to vineyards still had over 100 acres (40ha) that could be grazed. Statistical models showed that land use policy did not have a significant impact on these changes. Our results show the importance of distinguishing between land use and land cover to understand social and natural system changes.

ABSTRACT Understanding the scale of land use/cover (LULC) map and its impacts on representing LULC is central to address earth observation issues. However, there is an absence of quantitative uncertainty evaluation of upscaled maps to be used over decades. An approach based on the Shannon entropy theory was then proposed to tackle this issue by reporting categorical heterogeneity information contained in upscaled pixels. The Majority Rule-Based aggregation algorithm was performed to generate upscaled maps at different widely used scales using a national LU map. The results reveal that substantial uncertainties inevitably exist in the upscaled maps. Additionally, the analysts demonstrate that the proposed approach can-and-indeed accurately provide spatially uncertain information of upscaled maps. These findings suggest that this approach is necessary for users to most effectively use these maps in earth observation models and should be extensively used in the future work.

ABSTRACT Tropical rainforest ecosystems that function as biodiversity pools had been undermined because of anthropogenic activities. Research has shown that protected areas (PAs) have become the first safeguard for biodiversity. However, how to measure the effectiveness of PAs remains unclear. We present spatiotemporal changes within the PAs and non-PAs in the Leuser Ecosystem, which is one of the significant global landscapes, using intensity analysis during two time periods and propensity score matching to investigate the effectiveness of PAs. We classified land cover using machine learning based on remotely sensed data. Our results revealed the effectiveness of PAs compared with non-PAs. The new conservation intervention after 2008 resulted in the deacceleration of deforestation from 2000–2010 to 2010–2020. In addition, PAs can reduce deforestation two times more effectively than non-PAs. Therefore, PAs and good governance within the Leuser Ecosystem are crucial in maintaining the natural ecosystem to address global conservation targets.

ABSTRACT The identification or delineation of a spatially contiguous area within a larger region is an important land use planning problem and is utilized across a range of disciplines and management contexts. This involves the selection of individual spatial units, such as parcels, forest stands, management areas, etc., for an intended goal, purpose, usage and/or activity with constraints on maximum size along with contiguity requirements. The goal of this paper is to present a new spatial optimization model that can be used to simultaneously delineate single or multiple patches, where each is a contiguous set of individual spatial units, meets specific size requirements and is spatially distinct. We structure this new model as a mixed integer-linear program. We also present an application of this new model to a land management problem encountered by the USDA Forest Service involving wildfire mitigation efforts.

ABSTRACT In western Uganda, land inheritance has been the key means to bequeath livelihood opportunities to children, but land competition is increasing rapidly. Shrinking parcels and higher prices have made bequeathing land more difficult, especially for women, whose control over land has been customarily limited. We surveyed 50 rural women about their strategies and challenges investing in children’s future livelihoods. We present both quantitative and qualitative analysis of their responses. Over 80% believed it is better to invest in education rather than land, to help children secure remunerative off-farm jobs. Mothers wanted the majority of their children to leave the village to seek work elsewhere, equally for sons and daughters. Many also wished to provide a land-based safety net but worried this was no longer possible. Mothers’ assets affected both aspirations for and educational attainment of their children, highlighting potential for intensifying land competition to exacerbate inequality.

Urban land use transitions along with the rapid urbanization development cause obvious negative effects on the local ecological system. This paper explored the dynamic patterns of land use in central China’s largest city Wuhan, using high-resolution Landsat Thematic Mapper (TM) data in 1990, 2000 and 2010. The aggregate ecosystem services value, its dynamics, and spatial features were discussed based on the equivalent value per unit area approach, with the revision of Xie et al.’s (2015) unit parameters, adapted to Wuhan’s local situation. The results indicated that Wuhan’s ecosystem services value had been experiencing a continuous decrease during 1990 and 2000 and the following decade. The decrease was mainly due to urban expansion. However, Wuhan’s ecosystem services value decreased less between 2000 and 2010 with a much faster urban expansion pace than those in the former decade. The results illustrated that urban development severely affected ponds, rivers/lakes in their contribution to the ecosystem services that they naturally provided. Ponds and rivers/lakes contributed importantly to urban ecosystem services, even with a small proportion of area. Farmland contributed highly to urban expansion space as well as highly to the loss of related ecosystem services such as food provision and nutrient cycle maintenance. Forest land followed with an important contribution to climate regulation, soil conservation and waste regulation. The optimization of land use structure and configuration could improve urban ecosystem services. The authors conclude that even though the awareness of ecological resources conservation and sustainable development planning is emphasized, the practices are still in a challenge. The integration of ecosystem services dynamics to urban planning is an essential way that the large cities of China can realize sustainable development during its rapid urbanization.
伴随着城市化快速发展的城市土地利用转型对当地生态系统产生了明显的负面影响。利用高分辨率Landsat Thematic Mapper (TM)数据，对1990年、2000年和2010年中国中部最大城市武汉的土地利用动态格局进行了研究。基于单位面积等值法，并对Xie et al.(2015)的单位参数进行了修正，探讨了武汉市生态系统总服务价值、动态特征和空间特征。结果表明:1990 - 2000年及其后10年，武汉市生态系统服务价值呈持续下降趋势;减少的主要原因是城市扩张。2000 - 2010年武汉市生态系统服务价值下降幅度较小，城市扩张速度明显快于前10年。结果表明，城市发展严重影响了池塘、河流/湖泊对其自然提供的生态系统服务的贡献。池塘和河流/湖泊对城市生态系统服务做出了重要贡献，即使面积很小。农田对城市扩张空间的贡献很大，对食物供应和养分循环维持等相关生态系统服务的损失也很大。其次是林地，对气候调节、土壤保持和废物调节有重要贡献。土地利用结构和配置的优化可以改善城市生态系统服务。本文认为，虽然强调了生态资源保护意识和可持续发展规划，但在实践中仍面临挑战。将生态系统服务动态与城市规划相结合是中国大城市在快速城市化进程中实现可持续发展的重要途径。

Spherical fuzzy set (SFS) is also one of the fundamental concepts for address more uncertainties in decision problems than the existing structures of fuzzy sets, and thus its implementation was more substantial. The well-known sine trigonometric function maintains the periodicity and symmetry of the origin in nature and thus satisfies the expectations of the experts over the multi parameters. Taking this feature and the significance of the SFSs into the consideration, the main objective of the article is to describe some reliable sine trigonometric laws for SFSs. Associated with these laws, we develop new average and geometric aggregation operators to aggregate the Spherical fuzzy numbers. Then, we presented a group decision-making strategy to address the multi-attribute group decision-making problem using the developed aggregation operators. To verify the value of the defined operators, a MAGDM strategy is provided along with an application for the selection of an authentic COVID-19 laboratory. Moreover, a comparative study is also performed to present the effectiveness of the developed approach.

This article Based on the field survey of 15000 farmers in Gansu, Ningxia, Inner Mongolia, Shaanxi and Qinghai provinces, we used mediator model,analyzed the impact of farmers' livelihood strategies on land circulation and income growth. The research results showed that the farmers’ dependence on land gradually weakened, the willingness of farmland transfer decline, the willingness of farmland transfer to rise; Farmer’s livelihood strategy directly affected income growth, while indirectly income growth by land circulation. Therefore, further promotion on agricultural science and technology achievements transformation and talent support for rural development should be strengthened, the agricultural support system which increases farmers' income should be promoted, farmers' agricultural labor remuneration and scale economic benefit should be encouraged by new styles of agricultural businesses. We should continue to strengthen the progress of the land property rights system, promote the transfer of rural surplus labor through skills training, employment and encourage startups, so that farmers will be both participants and beneficiaries from the farmland transfer.
