    Underground sites have become an attractive tourist destination for an increasing number of visitors. This flow of visitors has made sustainability a major issue, that is, the way in which tourism development ensures economic benefits for host communities and respects local identity without compromising the environmental resources.

    Etiopía

    Eucalyptus wood products contribute significantly to the income of smallholder growers in many parts of Ethiopia. This has incentivized smallholders to convert arable lands to Eucalyptus plantation. Given the limited attention and availability of empirical evidence, this study examined the Eucalyptus wood products value chain in terms of the actors engaged, the type and importance of channels, margins analysis and the overall value chain governance in the main Eucalyptus growing areas of the Blue Nile highlands of Northwestern Ethiopia in 2019/2020.

    With the continuous urbanization, China is facing a dilemma of achieving two conflicting targets in land governance, i.e., the continuous supply of urban construction land to support urbanization and the preservation of cultivated land for food security. Under China’s dual land system, the implementation of the “Linkage between Urban-land Taking and Rural-land Giving” (Linkage) policy is of great significance in promoting more inclusive urbanization by commodifying the land development right and connecting urban and rural land markets.

    Rwanda

    Land, as a valuable natural resource, is an important pillar of Rwanda’s sustainable development. The majority of Rwanda’s 80% rural population rely on agriculture for their livelihood, and land is crucial for agriculture. However, since a high population density has made land a scarce commodity, growth in the agricultural sector and plans for rapid urbanisation are being constrained, and cross-sectoral trade-offs are becoming increasingly important, with a risk that long-term sustainability may be threatened if these trade-offs are not considered.

    New towns are a major form of urban growth in China. In recent years, increasing numbers of large new town projects have been planned and built in and around existing cities. These new town projects have frequently been employed by city governments as central elements of pro-growth strategies, based on ideas of urban entrepreneurialism, which seek to promote economic growth, project a dynamic city image, and increase urban competitiveness. This article studies how the pro-growth, urban entrepreneurial approach affects the planning and development of Chinese megacities.

    The study set out to understand drivers of Land-Use Land Cover (LULC) changes in dry-land areas and investigate factors helping mitigate the adverse impacts of climate anomalies on LULC changes. By employing a mixed-methods design, it combined LULC data with socioeconomic and climatic data, to analyze the pattern of LULC changes and its socioeconomic and climatic driving forces along with moderating factors. It was found that rangeland decreased by 764 km2 (13% of total area) between 1986 and 2015.

    The ecological benefit of cultivated land is the non-market value or ecological service value created by cultivated land protection. Based on the trinity concept of comprehensive protection of quantity, quality, and ecology of cultivated land, this study calculates the ecological benefits of cultivated land protection in the Yangtze River Economic Belt. Through the theory of ecological supply and demand balance, the study estimated the ecological benefit spillover of cultivated land protection in the basin.

    Ecological degradation caused by rapid urbanisation has presented great challenges in southern China. Fractional vegetation cover (FVC) has long been the most common and sensitive index to describe vegetation growth and to monitor vegetation degradation. However, most of the studies have failed to adequately explore the complexity of the relationship between fractional vegetation cover (FVC) and impact factors.

    This study has examined the process of urban space development in Krakow (southern Poland) using two developments as an example. The planning documents were analysed and spatial data obtained from the CAPAP (Centre for Spatial Analysis of Public Administration) project were processed. The data source for analysis comprised 2D outlines of certain buildings from the topographic object database (BDOT10k), elevation data from lidar aerial laser scanning at a density of 12 points per square meter and a numerical terrain model (NMT) with a one-meter mesh grid.

    China

    In the current context of rapid global urbanization, China’s urbanization is also accelerating, and the rational planning and sustainable use of state land and space have become a growing concern. The expansion of urban geographic space is inevitably accompanied by the massive expropriation of rural land.
