Promoting wildlife habitat on working agricultural land is a growing conservation priority, and agri-environment schemes are using payments for environmental services (PES) to reach these privately owned lands. PES can be ecologically effective, but also expensive, putting pressure cost-effective, maximizing the value of their limited resources. This study assesses cost-effectiveness four in Ca...

Food security in the East African Highlands is dependent upon the productivity of lands managed by smallholders who face difficult challenges in maintaining the fertility of their soils. A study was conducted to identify indicators of soil fertility status that are consistent with farmers’ perceptions of soil fertility. Physical, chemical and biological properties of soils were measured from pa...

Urban sprawl (US), propelled by rapid population growth leads to the shrinkage of productive agricultural lands and pristine forests in the suburban areas and, in turn, adversely affects the provision of ecosystem services. The quantification of US is thus crucial for effective urban planning and environmental management. Like many megacities in fast growing developing countries, Chennai, the c...

Degraded lands have often been suggested as a solution to issues of land scarcity and as an ideal way to meet mounting global demands for agricultural goods, but their locations and conditions are not well known. Four approaches have been used to assess degraded lands at the global scale: expert opinion, satellite observation, biophysical models, and taking inventory of abandoned agricultural l...

Construction of coastal ports makes port area and nearby sea area become high risk region of ecological emergency and environmental pollution. It is helpful for providing references to protect ecological environment of port by quantifying port ecological carrying capacity. This paper will transfer resources and energy consumed in port production and operation to four ecological productive lands...

The Upper Yangtze River Basin comprises a densely-populated agricultural region with mountainous and hilly landforms. Intensive cultivation has been extended onto steep hillslopes, which constitute the principal source area for sediment production. Soil conservation on sloping arable lands is thus of utmost priority for persisting sustainable agricultural production and maintaining sound ecosys...

Wireless Sensor Networks have been used for various purposes in different spaces from the field of industry to our home surroundings because of their capacity to powerfully screen remote areas such as agriculture farm lands, health care system etc [1]. DEC (Deterministic Energy Efficient Clustering) protocol is fast, dispersive, organizing toward oneself and much productive as far as continuity...

It has been conservatively estimated that there are 74,356 kIn of running waters in the Pacific Northwest (Oregon, Washington, Idaho) that can C'r do support fisheries (Brin­ son et aI. 1981). On public lands in Oregon, the Bureau of Land Management (1980) es­ timates that 71,135 ha are dominated by riparian communities. These ecosystems are among the most productive wildlife habitats in North ...
