Marginal areas in economically advanced countries are a critical issue that European and national policies have been addressing for some time. These affected by depopulation, infrastructural gaps labor systems do not reach the corresponding levels where often agriculture still plays role. In Italy, despite fact National Strategy Inner Areas (SNAI) has active about decade with aim of increasing territorial cohesion these fragile areas, rather limited results achieved terms halting economic marginalization demographic decline. this specific context, our work is aimed at analyzing land use changes, loss ecosystem services trends Mediterranean region (Irpinia—Southern Italy) on district municipal scales last 30 years (1990–2018) to capture current, subtle socio-economic dynamics. The analysis carried out indicated substantial increase urban due development new industrial discontinuous fabric (urban sprawl) expense natural (mainly meadows shrublands). agricultural remained substantially unchanged extension, slight heterogeneous an expansion high-value crops (vineyards), most suitable multifunctional activities (experiential rural tourism). trend highlighted widespread phenomenon exception those municipalities who orbit around provincial capital Avellino. depopulation mostly located inner characterized more rugged morphology gaps. Unexpectedly, show significant anticorrelation among population which indicator social phenomena as complex they underestimated. As final step, highlights also carbon storage mainly attributable soil sealing large areas. This study can help comprehensively understand conditions marginal Europe over recent decades light main dynamics better direct efforts towards containment human hemorrhage, consisting persistently negative migratory rates, sustainable empowerment geo-economic peripheries.

The aim of this research is the quantitative characterization climate risk, in order to support spatial planners choosing resilient adaptive actions at urban and territorial scale. According Sixth Assessment Report Intergovernmental Panel on Climate Change, risk combination hazard, exposure, vulnerability parameters. Vulnerability a function sensitivity capacity. From planners' point view, expresses degree which study area influenced by variability. In regard, authors have implemented GeoDataBase quantify over southern Italian region, analyzing long-term measured meteorological data (air temperature precipitation) subsequently generating synthetic maps interpolating data. As result, present Calabria providing useful physical data-based identification priority areas for planning purposes.

Nghiên cứu sử dụng mô hình RUSLE kết hợp với công nghệ GIS và viễn thám để đánh giá về mức độ xói mòn đất do mưa tại lưu vực Sông Công trên địa bàn một số xã huyện Định Hóa. Kết quả cho thấy 66,62% diện tích không bị mòn. Tuy nhiên, khu nhẹ trung bình (chiếm 28,37% 4,56%) tập ở các có dốc như Thanh Định, Điềm Mặc Bình Thành, trong khi mạnh chỉ chiếm 0,45%, rải rác Phú Đình, Mặc. Để bảo vệ tài nguyên bền vững, nghiên nhấn cần duy trì lớp phủ thực vật ít mòn, áp canh tác theo đường đồng quản lý nước hiệu quả. Tại tăng cường trồng cây che cải thiện hệ thống thoát nước. Đồng thời, việc dõi tình trạng cùng tuyên truyền nâng cao nhận thức của người dân, sẽ góp phần giảm thiểu nguy cơ phát triển vững
