Multiple-Scale Geodiversity: Determination, Classification and Implications

Dear Colleagues,

Geodiversity is defined as the natural heterogeneity of geological, geomorphic, and soil characteristics, and demonstrates the complexity of natural systems. Spatial scales in studies on geodiversity have usually ranged between watershed and vegetation patchiness. Many studies have assessed the impact of geodiversity on biodiversity, and particularly on vegetation diversity. Other studies have focused on the impact of geodiversity on surface processes, with the specific impact on hydrological connectivity and its implications for water overland flow, soil erosion, and hydro-geomorphic functioning. Overall, it seems that geodiversity affects natural cycles, environmental sustainability, and ecosystem services. Recent studies have highlighted the ameliorative impact of geodiversity on the susceptibility of water-limited ecosystems to climatic change. Specifically, recent modelling studies have shown that geodiversity increases the durability and resilience of high-geodiversity ecosystems in long-term drought episodes. Despite being predominantly determined by natural conditions, geodiversity can also be formed by anthropogenic activities. Practically, human-made geodiversity, either intentional or unintentional, can either restore or degrade the ecological functioning of target lands, such as water harvesting systems or trampling routes formed by grazing of domesticated animals. This Special Issue will encompass studies dealing with the entire range of spatial and temporal scales, as well as with all biomes and land uses, where geodiversity is relevant. Field and experimental studies and modeling and conceptual studies are welcomed.

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 250 words) can be sent to the Editorial Office for assessment.

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.
