In arid and semiarid regions that have deep soils, plant root systems can extract soil water to a depth of 20m or more. An accurate evaluation of soil water conditions in such regions is essential in order to improve the understanding of the role of soils as a water pool and to design scientifically based water management strategies. However, the vertical distribution of soil water and its storage in deeper layers are unclear due to the shortage of field data.
Increase in soil nutrients in intensively managed cash-crop agricultural ecosystems in the Guanting Reservoir catchment, Beijing, China
Since the late 1970s, transitions in socioeconomic status and new governmental policies have led to drastic changes in agricultural land use types and farm management practices across rural China, such as an increase in the area of land cultivated for cash–crops (e.g. vegetables and orchards) and intensive fertilization and irrigation of this land. How this more intensive management and land use for the more profitable cash crops affects soil nutrients is of great concern for carbon, soil and water quality management.
Relative sea-level rise in the Basque coast (N Spain): Different environmental consequences on the coastal area
Short sediment cores taken from (i) a recently regenerated salt marsh (Plentzia estuary), (ii) an incipient marsh and (iii) a pristine marsh (Urdaibai estuary), have been interpreted for evidence of environmental impacts and sea-level change on the basis of microfaunal and geochemical determinations and historical land management data. Under the current relative sea-level rise scenario, it might be expected that salt marsh ecosystems lose their ability to keep up with tidal flooding and drown following a transgressional pattern where marsh vegetation replaces woody plant species.
Land demand for ethanol production
Several key indicators of the sustainability of biofuels are related to the land used to produce the feedstock.
Conflict resolution through collaboration: Preconditions and limitations in forest and nature conservation controversies
Increasing competition over the world's forest resources will likely aggravate conflict, though conflict should not be seen as bad per se. As the challenge is to develop institutions and practices capable of handling conflict constructively, various collaborative approaches involving disputing actors are evolving worldwide. In Sweden, most such approaches pertain to protected areas and few involve commercial forestry.
