Estimation and Determination of Carrying Capacity in Loblolly Pine
Stand carrying capacity is the maximum size of population for a species under given environmental conditions. Site resources limit the maximum volume or biomass that can be sustained in forest stands. This study was aimed at estimating and determining the carrying capacity in loblolly pine. Maximum …

An assessment of recreational carrying capacity at Infanta, South Cape
… are made. An assessment of recreational carrying capacity indicates in broad terms what levels of use are acceptable for the different recreational activities pursued in the area. At the present population pressure these levels are already attained or exceeded for most activities. Major …

Quantifying China's carrying capacity : using optimization to explore sustainable food production
… region for given natural resources and diet (the carrying capacity). A quantitative assessment of carrying capacity provides insight into the food security of the study region as well as the stress on the environmental system; in addition, this methodology can be used to assess the carrying …

Evaluation of environmental carrying capacity and application of the sustainability target method
The environmental carrying capacity (CC) is defined as the capacity of the earth to absorb or tolerate potentially stressful burdens imparted at various scales and locations, that is, to accommodate the ecological stresses without showing permanent damage. The CC can be used as a reference dataset …

The concept of carrying capacity as a tool for managing scenic roadways
… on many of our nation's scenic highways. The carrying capacity concept says that there is an acceptable level of use or change for a resource beyond which that resource will be significantly degraded. This thesis examines the applicability of this concept to the problems of crowding and …

Regional food security in south-central Appalachia: Connecting diet, land requirement, and agricultural carrying capacity
… and nutritional sciences to test the capacity of regional food systems to meet complete diet food need in the south-central Appalachian foodshed. First, a complete diet approach was applied to the entire foodshed to test the influence of animal product and fat consumption on the land …

Fecal Coliform as an Indicator of Water Quality and Recreational Carrying Capacity At Ozark National Scenic Riverways
Visitor impacts on the Ozark National Scenic Riverways (ONSR) has been a continuing concern of the park management. Preliminary studies from 1980 indicated a postive relationship between levels of canoe use and fecal coliform densities. Water quality data were collected at seven locations on the …

The appropriated carrying capacity of tomato production : comparing the ecological footprints of hydroponic greenhouse and mechanized field operations
… of the ecological footprint (or appropriated carrying capacity) to compare the productivity of hydroponic agriculture with that of conventional open field operations. I assess and compare the biophysical inputs required by these operations to produce 1000 tonnes of tomatoes. These figures are …

The designing and testing of a game to demonstrate concepts related to the human carrying capacity of New Zealand
… certain concepts related to New Zealand's human carrying capacity. Principally, the game seeks to show that if the population rises above a particular level, the quality of life will deteriorate. Initially, games are considered in general, with particular reference to the use of games for …

A finite element calculation method for the heat transfer effects on the current-carrying capacity of underground electrical cables
… thermal conductivity and a negligible thermal capacity. The individual thermal conductivity of each air gap is calculated by assuming the convection and radiation heat exchanges as separate thermal resistances acting in parallel between cables and ducts. The convection component is calculated …

An extension of the recreational carrying capacity concept : a procedure for recreation resource allocation in the planning of natural landsapes
Investigating the recreational carrying capacity of a new coastal national park in South Africa was the initial problem to be addressed. However, an examination of the concept and attempts to operationalize it shows clearly that it is illusory. Instead, the problem is conceived of as a process in …

The lateral load carrying capacity of wall ties used in cavity wall construction in the Western Cape : a comparison between the Butterfly-type wire tie and the Crimped-type wire tie
The aim of the testing was to compare the relative positives and negatives of the Butterfly Tie and the Crimped lie as regards to water transfer, tensile and compression strengths based on the Australian Code [AS 2699-l 984] requirements as it is more comprehensive. The reason was because the …
