Since the Land Administration Bureau was established in 1986, China has carried out the national land-use planning twice, of which the first was focused on "serving for social and economic development", and the second converted to “protecting arable land". At present a new round of land-use planning is ongoing (2005-2020), but the aims and requirements are even more and higher(Zheng Weiyuan,200...

Woody perennials subjected to root oxygen-stress often respond with varying levels of reduced assimilation and leaf gas exchange. Yet in most of these studies, seedlings grown in pots were subjected to experimental conditions that rarely exist in nature for mature trees. To determine if flooding mature orchard-grown pecan (Carya illinoiensis (Wangh) K. Koch) results in a similar depressed photo...

Landowner perceptions of damage caused by beavers (Castor canadensis) and of beaver control programs in Arkansas were determined by mail survey. Beavers were present on lands owned by 36% of the 1,716 respondents. Girdled timber, blocked culverts and flooded timber were the first, second and third most common damages reported, respectively. Thirty-two percent of all respondents and 90% of those...

BACKGROUND In winter 2013/14 there was widespread flooding in England. Previous studies have described an increased prevalence of psychological morbidity six months after flooding. Disruption to essential services may increase morbidity however there have been no studies examining whether those experiencing disruption but not directly flooded are affected. The National Study of Flooding and Hea...

Abstract Monitoring land use/land cover (LULC) change is urgently needed in a sustainable environmental management process. Many aspects require accurate information about past, present, and future projections to develop strategies. Jakarta its surrounding cities (Tangerang Bekasi) called JATABEK one area frequently flooded. This research aimed derive the LULC map by integrating remote sensing ...

BACKGROUND AND AIMS Erythrina speciosa is a Neotropical tree that grows mainly in moist habitats. To characterize the physiological, morphological and growth responses to soil water saturation, young plants of E. speciosa were subjected experimentally to soil flooding. METHODS Flooding was imposed from 2 to 4 cm above the soil surface in water-filled tanks for 60 d. Non-flooded (control) plan...

Water extraction from floodplain river systems may alter patterns of inundation of adjacent wetlands and lead to loss of aquatic biodiversity. Water reaching the Okavango Delta (Delta), Botswana, may decrease due to excessive water extraction and climate change. However, due to poor understanding of the link between inundation of wetlands and biological responses, it is difficult to assess the ...
