Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue of Land entitled “Land Use Policy and Food Security: 2nd Edition”.

Food security is the foundation of the stable development of human society and economy, and the land use policy of a country is closely related to food security. For example, in recent years, China has implemented a large number of land use policies (such as high-standard farmland construction, one household and one field, and the separation of three rights, etc.), which have profoundly affected the development of related markets (non-agricultural employment market, land transfer market, and socialized service market), changed the pattern of land use by farmers (self-support, transfer and abandon land), and contributed to the food security and sustainable development of China and even the world. However, we still lack systematic research and understanding on how these useful land use policies systematically affect market development, how to reshape farmers' land use patterns, how to change farmers’ planting structure, and how to ensure farmers’ food security and sustainable development. Based on this background, this Special Issue is dedicated to building a theoretical and practical research platform for studies systematically assessing the direct and indirect impacts of land use policies on food security and sustainable development. Original research and review articles in this research field are welcome. Topics of interest include, but are not limited to, the following: 

  • Evolution of logic and enlightenment of land use policy;
  • Land use policy and market development;
  • Land use policy and food security;
  • Land use policy and sustainable development.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Land is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Given the constraints of limited cultivated land resources, ensuring and enhancing crop productivity are crucial for food security. This study takes Chengdu as a case study. Using the cultivated land productivity (CLP) evaluation model, we calculated the cultivated land productivity index (CLPI) and analyzed its spatial distribution characteristics. The Geographical Detector model was employed to identify the main factors influencing CLP, and corresponding countermeasures and measures were proposed based on the limiting degrees of these factors. The findings reveal that Chengdu’s CLP index ranges from 1231 to 3053. Global spatial autocorrelation analysis indicates a spatial agglomeration pattern in Chengdu’s overall crop productivity distribution. The local spatial autocorrelation analysis demonstrates that township (street)-level crop productivity in Chengdu is primarily characterized by “high–high”, “low–low”, and “low–high” clusters. Key factors influencing the spatial differentiation of CLP in Chengdu include the agronomic management level, soil bulk density, irrigation guarantee rate, soil body configuration, field slope, and farmland flood control standard. Interaction detection shows that there are both double-factor and nonlinear enhancements among the factors. Specifically, the interaction between soil bulk density and the agronomic management level among other factors have the most explanatory power for the spatial differentiation of CLP. The CLP in Chengdu is highly restricted by its technical level, with the agronomic management level severely limiting CLP by more than 50%. These research results provide a theoretical reference for regional high-standard farmland construction and the protection and utilization of cultivated land resources. Full article
