Due to the multiple impacts of landform effects, spatial heterogeneity and land use policies, farmland dynamics in mountainous areas are complicated. This study investigated farmland dynamics based on land use data from a typical mountainous area, Panxi, in China for 1990, 2000 and 2010, discussed the relationship between altitude, slope and farmland changes and presented an analysis of the driving forces of farmland change. Our findings are as follows: (1) from 1990 to 2010, the area of converted farmland was relatively small (313 km2), accounting for only 2.6% of the region’s farmland.

Forests are under pressure from land use change due to anthropogenic activities. Land use change and harvest are the main disturbances of forest landscape changes. Few studies have focused on the relative contributions of different disturbances. In this study, we used the CA-Markov model, a land-use change model, coupled with a forest landscape model, LANDIS-II, to simulate dynamic change in Taihe County, China, from 2010 to 2050. Scenarios analysis was conducted to quantify the relative contributions of land use change and harvest.

When developing land to meet various human needs, conducting assessments of different alternatives regarding their sustainability is critical. Among different alternatives of land-use, devoting land to bioenergy is relatively novel, in high demand, and important for addressing the energy crisis and mitigating carbon emissions. Furthermore, the competition and disputes among limited land-use for bioenergy and the combination of food production and housing are tense. Thus, which alternative of land-use is more sustainable is an important question, yet it is still under-investigated.

In Hong Kong, reclamation is the main method for developing new land use areas as most country parks and mountains are protected under a land policy that emphasizes conservation for their high ecological value. Therefore, the land use for urbanized area in Hong Kong is limited, which has become an issue of concern. Hong Kong’s population is increasing; however, the amount of available land use is insufficient to meet the demand. Developing a high density of buildings is one of the critical strategies of Hong Kong’s government.

The paper examines the applicability of the concept of ‘generation rent’ in the ‘super-homeownership’ housing regime and better-off focused welfare regime of Hungary. Available official statistical and survey data show the increase in private rentals among young households, and the appearance of private rental housing as a potential longer-term solution in the attitudes of young people towards housing. In the Hungarian context, the strong role of intergenerational transfers in access to home ownership and public housing policies contribute to the development of a ‘generation rent’.

This study assesses the impact of insecure land tenure on sustainable agricultural development in Africa to demonstrate how the economic profitability of agriculture strongly depends on land tenure security. The Republic of Benin is used as the case study following the country’s recent enactment of land law 2013-01 that focuses on reorganizing the land sector, which has suffered from inappropriate management since the colonial era.

Compelling evidence in Sub-Saharan Africa (SSA) shows that Climate-Smart Agriculture (CSA) has a positive impact on agricultural productivity. However, the uptake of CSA remains low, which is related to anthropogenic, or human-related, decisions about CSA and agricultural land use. This paper assesses households’ decisions to allocate agricultural land to CSA technologies across space and over time. We use the state-contingent theory, mixed methods, and mixed data sources. While agricultural land is increasing, forest land is decreasing across countries in SSA.

Improving agricultural production efficiency is an effective means to ensure food security and promote agricultural sustainable development in China. Stable agricultural land property rights help optimize the allocation of production factors and improve production efficiency, and it is of great practical significance to study the influence of farmland tenure security on agricultural production efficiency.

A stable farmland tenure can optimize farmers’ allocation of production factors and then determine the income level and structure of farmers. In recent years, the reform of China’s farmland tenure system had been making efforts to strengthen the stability of farmland tenures. Will the farmland tenure security restrict agricultural development? Based on the data of the 2018 China Labor Dynamics Survey (CLDS), this paper empirically analyzes the impact of farmland tenure stability on rural household income and its mechanism.

One of the world’s major issues is climate change, which has a significant impact on ecosystems, human beings, agricultural productivity, water resources, and environmental management. The General Circulation Models (GCMs), specially the recently released (coupled model intercomparison project six) CMIP6 are very indispensable to understand and support decision makers to identify adaptation strategies in response to future climate change in a basin. However, proper selection of skillful GCMs and future climate assessment is a prior task to climate impact studies.
