Special Issue Information

Dear Colleagues,

Land degradation has become one of the biggest environmental challenges that human society is currently facing. All these physical and ecological attributes of land systems are constantly eroded by the multitude of land degradation pathways/processes that occur on various spatial scales throughout the world. As an interdisciplinary and complex issue, land degradation is currently caused by 17 land degradation pathways (aridity, biological invasions, coastal erosion, land erosion by water, land erosion by wind, land pollution, land subsidence, landslides, permafrost thawing, salinization, soil acidification, soil biodiversity loss, soil compaction, soil organic carbon loss, soil sealing, vegetation degradation, and water logging). However, recent progresses in land degradation processes and control are short of large-scale, long-term, interdisciplinary, and multidimensional studies.

The aim of this Special Issue is to collect papers (original research articles and review papers) to give insights about large-scale, long-term, interdisciplinary, and multidimensional studies on land degradation in different degradation pathways. New findings and progresses on land degradation and control are also welcome. The discussion of new forms of land degradation and pathways is encouraged in the Special Issue.

This Special Issue will welcome manuscripts that link the following themes:

  • Vegetation degradation and restoration;
  • Land use and degradation;
  • Land degradation pathways and control;
  • Soil carbon loss and sequestration;
  • Farmland degradation and protection;
  • Soil erosion and degradation;
  • Long-term land degradation effects;
  • Land degradation and ecosystem services;
  • Land degradation and environment effects.

We look forward to receiving your original research articles and reviews.

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.

Investigating the changes in the runoff and sediment coupling relationship in the Middle Yellow River Basin of China can not only deepen the understanding of soil loss control in arid areas, but also help solve key issues of regional ecological protection. Since the 1960s, soil- and water-conservation projects have been implemented in the Middle Yellow River Basin, inducing a significant reduction in runoff and sediment and changes in the relationship between runoff and sediment. The study identified the change points of coupling relationship between runoff and sediment in the Wuding River Basin (WRB) by constructing a diagnostic method based on coupling coordination degree and the Pettitt test; the study validated this using the Copula function and analyzed the impacts of erosion energy and underlying surface factors. The results showed the following: (1) the method based on coupling coordination degree and the Pettit test could accurately reflect the coupling relationship of runoff and sediment and identify two change points (1971 and 1996); (2) runoff and sediment in the WRB decreased gradually over three periods (P1, 1960–1970; P2, 1971–1995; P3, 1996–2020), with an average annual runoff of 15.34 × 108, 10.72 × 108, and 8.32 × 108 m3 and average annual sediment load of 1.84 × 108, 0.82 × 108, and 0.32 × 108 t, respectively; (3) the maximum possible joint design value of runoff and sediment under different return periods in P1 were all the highest, followed by P2 and P3, and the larger the return period, the higher the maximum possible joint design value; (4) runoff erosion power could promote runoff and sediment in PE (1960–2020), P1, P2 and P3 at a significant level, check dams and terrace could decrease runoff and sediment significantly in PE, and the highest contribution to runoff reduction was check dam (95.4%), while the highest contribution to sediment reduction was REP (93.8%). The study can provide a new way to analyze the changes in the runoff and sediment relationship and provide scientific support for runoff and sediment regulation in the Middle Yellow River Basin.
