Metropolitan food systems in developing countries: the perspective of urban metabolism
The paper focuses on urban food metabolism, by using the concept of the food system which includes the sub-systems of production, supply, distribution and consumption of food.

This article examines the Piedmont megapolitan political ecology and urban metabolism in Southern Appalachia. First, it considers the central role urban metabolic connections play in the region's pressing social and environmental crises. Second
, it illuminates these human and nonhuman urban metabolisms across the Piedmont megapolitan region using data from the Coweeta Long-Term Eco-logical Research (LTER) program, especially highlighting a growing “ring of asphalt” that epito-mizes several developing
changes to patterns of metabolism. The conclusion suggests that changing urban metabolisms indicated by Coweeta LTER data, ranging from flows of people to flows of wa-ter, pose a complicated problem for regional governance and vitality in the future.
An ecologo-physiologic and biochemical characteristics of about 150 plant species of the South-Western Kyzylkum are given. Originality of desert plants (in gas exchange and metabolism) that distinguish them from the others is revealed. A deep
capacity; and understanding its metabolism means that the causes and results of negative human impact can be explained. Presented are also the conditions and challenges which will have to be faced by the towns on their way to sustainability. - (L'A.).
in this review. As a consequence, the review has to be necessary selective, and papers are summarized under a series of general headings : macroecology as a subject; methods in macroecology; species range size distributions and range size variations; a metabolic
, and root systems are discussed, as are all their various interrelationships. The chapters on succession theory, the idea of climax, the law of relative constancy of location, and ecosystem metabolism in moist and arid environments provide the background
Soil erosion must be explored as a process in landscape metabolism. The multistage methodology developed for the purpose is based on point-by-point and areal logging techniques with different accuracy criteria. Transition from point-monitored
hydration and suggest moisture content > 14% is necessary to sustain such activity. The addition of nutrients did not trigger any significant increase in crust metabolic activity or photosynthetic response compared with deionised water over a 7-day period
. However, over longer periods (> 4 weeks) nutrient-enriched rainfall promoted an increase in cyanobacterial metabolic growth measures (chlorophyll a and greenness) compared with deionised water. The results show that the magnitude and frequency of hydration
Dynamic model of sheep productivity, describing the impact of environmental factors on main processes of vitability (basal metabolism, calorigenic activities, thermoregulation, grazing, growth) is offered. On the basis of this model it is possible
