Bulgaria has a long tradition of smallholder farming, predominantly producing for self-consumption. As a result of land reform and farm restructuring, many rural households received agricultural land. Some developed commercial farms but most households stayed as subsistence farmers and used their small pieces of land to produce for self-consumption and market the excess output to top up their non-farm incomes or meagre pensions. They had little capital and insecure access to markets.

Infield systems originated during the early Iron Age and existed until the 19th century, although passing many transitions and changes. The core features of infield systems were enclosed infields with hay-meadows and crop fields, and unenclosed outland mainly used for livestock grazing. We examine the transitions and changes of domesticated landscapes with infield systems using the framework of human niche construction, focusing on reciprocal causation affecting change in both culture and environment.

In recent years, market-oriented allocation of land has been promoted to support rural revitalization and urban–rural integrated development. To follow the path of sustainable development, it is necessary to improve the efficiency of resource utilization and to rationally allocate and use resources on the premise of ensuring the sustainable use of resources. This study aims to measure the degree of land marketization in Shaanxi Province, China during the period 2008–2019 and analyze its driving forces. The methods used include Gray Relation Analysis and Hot Spot Analysis.
