Improper Household Waste Disposal In Rural Territory.Case Study: Neamt County, Florin C. Mihai
Florin C MIHAI
Open dumping of waste generated and uncollected is the most common option in waste management schemes from rural areas. Lack of sanitation services or rudimentary waste management systems favored this practice. This paper proposes a method to estimate the amounts of household waste uncontrolled disposed at local administrative unit level (commune) for 2003 and 2010. Based on estimating the amounts of waste generated and uncollected are introduced new indicators in the quantitative analysis taking into account the household waste composition, individual composting of biodegradable waste or recyclable waste from households for a more proper assessment of waste disposed. Usually household …

Self management of natural resources has started to gain increasing attention as an alternative tool to command-and-control and market-based tools, but the fundamental question remains: is self management economically beneficial such that it should be promoted in the first place? This article uses a unique set of survey data from South Korea and applies an empirical strategy to provide some of the first quantitative evidence that self management is benefiting the fishermen. We find that positive benefits of fishery self management—an increase in fishery revenue and reduction in cost—are perceived by member fishermen, which is a good start considering the …

When considering the market for biomass from corn stover resources erosion and soil quality issues are important to consider. Removal of stover can be beneficial in some areas, especially when coordinated with other conservation practices, such as vegetative barrier strips and cover crops. However, benefits are highly dependent on several factors, namely if farmers see costs and benefits associated with erosion and the tradeoffs with the removal of biomass. This paper uses results from an integrated RUSLE2/WEPS model to incorporate six different regime choices, covering management, harvest and conservation, into a simple profit maximization model to show these tradeoffs.

The purpose of this paper is to introduce the concept of power density [Watts/m2] into economics. By introducing an explicit spatial structure into a simple general equilibrium model we are able to show how the power density of available energy resources determines the extent of energy exploitation, the density of urban agglomerations, and the peak level of income per capita. Using a simple Malthusian model to sort population across geographic space we demonstrate how the density of available energy supplies creates density in energy demands by agglomerating economic activity. We label this result the density-creates-density hypothesis and evaluate it using …

Human Development And Resources Use In The Coastal Zone: Influences On Human Health, Robert E. Bowen, Anamarija Frankic, Mary E. Davis
Robert E. Bowen
Coastal watersheds and nearshore marine areas are the most valuable and dynamic places on Earth. Human population growth is great in these regions, which are home to some of the most sensitive habitats in the world. Coastal areas provide more than half of the overall service value derived from the global environment (Costanza et al., 1997). Natural (e.g., hurricanes and tsunamis) and human pressures on this environment require it to constantly adjust. More than any other area, the global coast has defined the progress of human culture and continues to be a singular influence in how humans connect to the …
