Special Issue Information

Dear Colleagues,

Agricultural land use changes have influenced environmental systems on a global scale. As a consequence, such changes are one of the major issues facing environmental planning and management. Accordingly, without proper planning and management of agricultural land use and various agricultural activities, environmental systems as well as ecosystem services may suffer, particularly in terms of water quality, water quantity, as well as biodiversity. Therefore, to avoid and mitigate the impacts of such land use and agricultural activities on the environment, much effort in land use planning and management should be undertaken to assess the impacts of various land use changes on agricultural systems, model agricultural land use changes, evaluate land use planning and management strategies, as well as sustain ecosystem services.

In order to promote a deeper understanding of the impacts various land use changes and agricultural practices have on environmental systems, Environments is launching a Special Issue entitled “Impacts of Land Use Changes on Agricultural Environments”. Articles related, but not limited, to innovative or significant findings in: agricultural land use change studies; agricultural land use and water quality or quantity; the impacts of agricultural land use on ecosystem services; agricultural land use planning and modeling; agricultural land use management; and teleconnection of agricultural land use changes across various scales would be appropriate. Of course, studies on other related topics are welcome as long as they provide novel insights with the aim to investigate the issues or provide pertinent solutions for the negative effects that agricultural land use changes have on the environment.

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. Environments 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 1800 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.

Current intensification and changes in agricultural land use practices increase environmental impact that can be reduced by bridging the gap between socio-economic demands and scientific justification of sustainable agricultural land use. This can be achieved by replacing the goal of maximum crop yields with the goal of minimal environmental impact. This paper presents results of integrated crop simulation system development for analysis of alternative planning strategies in agricultural land use, with focus on the crop rotation influence on environmental sustainability. The effective tools used in analysis include (1) long-term analysis of changes in agricultural land using a dynamic crop model with daily time step; (2) justification of arbitrary crop rotation scheme of different agro-technologies and sparing measures; and (3) analysis of modern farming management methods using model-oriented approach. The results of study also include estimation of two alternative practices of crop harvesting including remaining or removing whole crop residues from the agricultural field and their influence on basic parameters of soil fertility. In addition, we analyzed comparative efficiency of different agricultural measures neglecting the negative influence of possible climate changes in long-term consequences. Corresponding efficiency rating is the following: organic fertilizer, green manure legume sparing harvesting, winter catch crop, and rotation scheme. Full article

Understanding long-term vegetation dynamics, their responses to climate, and other driving factors is crucial for integrated basin management in the Mekong River Basin (MRB) in a context of global change. In this study, Normalized Difference Vegetation Index (NDVI) and climate data from 1982 to 2013 were collected from Global Inventory Modeling and Mapping Studies (GIMMS) and Climate Research Unit Time Series Version 3.23 (CRU-TS 3.23). The long-term monthly average, Mann–Kendall trend (M–K) test, Sen’s slope, the coefficient of variation, correlation analysis, and the Partial Least Square Regression (PLSR) model with the Variable Importance in Projection (VIP) were applied in this study. The results showed an increasing temporal trend in NDVI and climate variables, especially temperature, in all vegetation types. There is a significantly increasing NDVI trend with relatively stable NDVI fluctuation across the majority of the MRB except in part of the Tibetan plateau in China. There is a positive spatial correlation between NDVI and air temperature, precipitation and PET (potential evapotranspiration) in the upper part of the basin. Air temperature is an important explanatory factor for all vegetation types, especially in forest ecosystems and croplands, while the role of precipitation and PET vary depending on vegetation type. In addition to physical aspects of the MRB, such as runoff, we conclude that the vegetation dynamics related to climate variables in the MRB should be considered in policies as the framework for ecological and environmental management plans of the MRB.
