The planting of sand-binding vegetation in the Qinghai Lake watershed at the northeastern edge of the Qinghai–Tibet Plateau began in 1980. For this paper, we took the desert on the eastern shore of Qinghai Lake as the study area. We analyzed a variety of aged Hippophae rhamnoides communities and aeolian activities, and we discuss the relationship between them. The main conclusions are as follows: (1) With an increasing number of binding years, the species composition became more abundant, natural vegetation began to recover, and biodiversity increased year by year.
Applying Text Mining for Identifying Future Signals of Land Administration
Companies and governmental agencies are increasingly seeking ways to explore emerging trends and issues that have the potential to shape up their future operational environments. This paper exploits text mining techniques for investigating future signals of the land administration sector. After a careful review of previous literature on the detection of future signals through text mining, we propose the use of topic models to enhance the interpretation of future signals.
Temporal Variation in Preferential Water Flow during Natural Vegetation Restoration on Abandoned Farmland in the Loess Plateau of China
The restoration of vegetation in abandoned farmlands is an effective approach to control soil erosion on the Chinese Loess Plateau. However, few studies have investigated the effect of natural restoration age on the infiltration patterns and preferential flow in soil layers. This study examined the effect of the temporal variations in the degree of preferential flow and their contribution on the total infiltration in abandoned farmlands restored with different vegetation communities.
Power of Agricultural Credit in Farmland Abandonment: Evidence from Rural China
Labor, land, and funds are keys to revitalizing rural areas around the world. Previous studies have focused on the impacts of funds on agricultural production, but placed little emphasis on its role in agricultural land-use transformation. Thus, this study explores the quantitative relationship between agricultural credit and farmland abandonment from the perspective of rural revitalization.
Household Land Allocations and the Youth Land Access Nexus: Evidence from the Techiman Area of Ghana
Building inclusive societies that reflect the needs of all categories of people within the social spectrum is critical to achieving sustainable development. This is reflected in the Sustainable Development Goals (SDGs) which among things seek to ‘by 2030, empower and promote the social, economic and political inclusion of all, irrespective of age, sex. This places enormous tasks on all governments especially in developing countries like Ghana to ensure that the youth are not left behind in access and control over land as a building block for economic empowerment.
