Soil salinity is a serious threat to coastal agriculture and has resulted in significant reduction agricultural output many regions. Jaffna Peninsula, semi-arid region located the northern-most part of Sri Lanka, also victim adverse effects salinity. This study investigated long-term soil changes their link with land use changes, especially paddy land. Two Landsat images from 1988 2019 were use...

The massive abandonment of arable land in Russia the 1990s had a heavy impact on country’s land-use structure. cessation cultivation leads to decrease provisioning ecosystem services within landscape, while creating an opportunity enhance supply diverse regulation services. Consideration this is increasingly important for environmental management and landscape planning. In article, we present a...

Forest succession on degraded tropical lands often is slowed by impoverished seed banks and low rates of seed dispersal. Within degraded landscapes, remnant forests are potential seed sources that could enhance nearby forest succession. The spatial extent that forest can influence succession, however, remains largely unstudied. In abandoned agricultural lands in Kibale National Park, Uganda, re...

Landscape in the southern United States changed dramatically during the 1930s and the following decades when massive agricultural and abandoned logging lands were converted to forest lands through natural restoration and silviculture. The impacts of this forest restoration on hydrology were investigated in this study by conducting numerical experiments with a regional climate model. Climatic an...

Broomsedge (Andropogon virginicus L.) is a dominant grass revegetating many abandoned coal-mined lands in West Virginia, USA. Residual soils on such sites are often characterized by low pH, low nutrients, and high aluminium. Experiments were conducted to assess the resistance of broomsedge to limited phosphorus (Pi) availability and to investigate the role that arbuscular mycorrhizal (AM) fungi...
