Soil quality evaluation is the foundation for understanding current situation of soil and promoting sustainable utilization land resources. However, impacts different long-term afforestation timescales on in a typical watershed valley area still insufficient. Here, based samples collected from years 2, 5, 11, 15, 31 natural sample plots with similar site conditions same region, gray target mode...

On the basis of monthly runoff series obtained in 1950-2013 and annual sediment load measured in 1956--2013 at five key hydrological stations in the middle and lower reaches of the Yangtze River basin, this study used the Mann-Kendall methods to identify trend and abrupt changes of runoff and sediment load in relation to human activities. The results were as follows: (1) The annual and flood se...

The worldwide historical carbon (C) losses due to Land Use and Land-Use Change between 1870 and 2014 are estimated at 148 Pg C (1 Pg=1billionton). South America is chosen for this study because its soils contain 10.3% (160 Pg C to 1-m depth) of the soil organic carbon stock of the world soils, it is home to 5.7% (0.419 billion people) of the world population, and accounts for 8.6% of the world ...

The paper is based on empirical research of a territorial transect in Cambodia’s Tonle Sap floodplain. flooded forests the Lake are determined by significant seasonal flood up to 13 m, where large gradient wetness and alluvia flow dramatically transform territory. zooms into case study inhabited RAMSAR area Boeng Chhmar with its five floating villages, which dispersed along waterways. one riche...

Abstract Afforestation and reforestation are considered important measures for climate change mitigation. Because the land area available tree planting may serve multiple purposes, striking right balance between goals other objectives is crucial. We conducted a survey of Norwegian population to investigate potential land-use conflicts that arise from executing large-scale afforestation programm...

BACKGROUND Deforestation due to tobacco farming began to raise concerns in the mid 1970s. Over the next 40 years, tobacco growing increased significantly and shifted markedly to low- and middle-income countries. The percentage of deforestation caused by tobacco farming reached 4 % globally by the early 2000s, although substantially higher in countries such as China (18 %), Zimbabwe (20 %), Mala...

BACKGROUND Enhancing water provision services is a common target in forest restoration projects worldwide due to growing concerns over freshwater scarcity. However, whether or not forest cover expansion or restoration can improve water provision services is still unclear and highly disputed. PURPOSE The goal of this review is to provide a balanced and impartial assessment of the impacts of fo...

Pollen is one of the primary causes of allergic rhinoconjunctivitis in urban centers. In the present study, the concentrations of 39 different pollens in the Santiago de Chile metropolitan area over the period 2009-2013 are characterized. The pollen was monitored daily using Burkard volumetric equipment. The contribution of each type of pollen and the corresponding time trends are evaluated. Th...

Drought stress is a major environmental factor limiting plant growth. Selection of drought-tolerant plants critical importance in vegetation restoration and forestation programs. Alnus subcordata Acer velutinum are two valuable, dominant, endemic species the Hyrcanian forests. There fast-growing significant diffuse-porous hardwood afforestation reforestation. One-year old seedlings both were ex...
