Three closed circles show how both economy and society are subsets of our planetary ecosystem. This view is useful in correcting the misconception sometimes drawn from the earlier “three pillars” diagram that parts of social and economic systems can exist unconcerned from vironmt.

Economic Development And Its Impact On The Environment

Natural Resource economics deals with the supply, demand, and allocation of Earth’s natural resources. One of the main goals of natural resource economics is to better understand the role of natural resources in the economy in order to develop more sustainable methods of managing those resources to ensure that they are available for future generations. Resource economists study the interactions between economic and natural systems with the goal of developing a sustainable and efficient economy.

Triple Bottom Line

Natural resource economics is an interdisciplinary field of academic research within economics that aims to address the relationships and interconnections between human economies and natural ecosystems. It focuses on how to operate an economy within the ecological limits of the Earth’s natural resources.

Resource economics brings together and connects various disciplines in the natural and social sciences related to the broader fields of earth science, human economics, and natural ecosystems.

Economic models must be adapted to accommodate the special characteristics of natural resource inputs. The traditional curriculum of natural resource economics emphasized fisheries models, forestry models, and mineral extraction models (ie fish, trees, and ore). However, in recent years, other resources, particularly air, water, global climate, and the “hostile resources” of gerals, have become increasingly important for policymaking.

Academic and policy interest has now moved beyond optimal commercial exploitation of the standard resource trio to compass management for other purposes. For example, natural resources have more broadly defined recreational as well as commercial values. Their mere existence can also contribute to overall social welfare levels.

The field of economics and policy focuses on the human aspect of vironmtal problems. Traditional areas of vironmtal and natural resource economics include welfare theory, land/place use, pollution control, resource extraction, and non-market valuation, and resource depletion.

Sustainability, vironmtal management and vironmtal policy. Research topics may include agriculture, transportation and urbanization, land use in poor and industrialized countries, international trade and vironmt, climate change, and methodological advances in non-market valuation.

Hotelling’s rule is an economic model of non-renewable resource management developed by Harold Hotelling in 1938. It shows that efficient exploitation of a non-renewable and inconsistent resource, under otherwise stable economic conditions, leads to depletion of the resource. This rule states that the increasing scarcity of resources will result in a net price or “Hotelling rt” that rises annually at a rate equal to the rate of interest. Incompatible resources of inorganic materials (i.e. minerals) are rare; Many resources can be increased by recycling and the availability and use of substitutes for d-used products (see below).

Vogely stated that the development of a mineral resource occurs in five stages: (1) Carat operating margin (production rate) governed by the proportion of the reserve (resource) already depleted. (2) Insive developmt margins governed by the trade-off between rising required investment and early realization of restructuring. (3) Extensive development margins where extraction of known but previously uneconomic deposits was initiated. (4) The cost per unit of extraction is highly uncertain, with the exploration margin of finding new deposits (resources) balanced against the cost of failure versus the search for usable resources (deposits) that have a marginal cost of extraction. Higher than the first three stages above. (5) Technical margin interacting with the first four stages. A special case of Gray-Hotelling (exhaustion) theory is that it only covers stages 1-3 and not the more important stages 4 and 5.

Sustainability, The Systems Approach And The Sustainable Development Goals

These conflicting views will be substantially mitigated, or at least mitigated, by a more in-depth consideration of resource-related topics in the next section.

The concept of perpetual resources is a complex one because the concept of resources is complex and changes to a lesser extent with new technology (usually more efficient recovery), new needs and new economics (eg changes in prices of materials, changes in energy costs, etc.). On the one hand, a material (and its resources) can end a period of scarcity and become a strategic and critical material (immediate exhaustion crisis), but on the other hand a material can fall out of use, its resource can continue. A resource may become a paleosource if it was not previously perpetuated and the material is almost entirely obsolete (e.g. Arrowhead-grade flint resources). Some of the complexities that affect a material’s resourcefulness include recyclability, availability of suitable substitutes for the material in its d-use products, and other less important factors.

The federal government suddenly became interested in resource issues on December 7, 1941, shortly after Japan cut off the United States from tin and rubber, making other materials such as tungsten very difficult to obtain. This was a worst-case scenario for resource acquisition, becoming a strategic and critical asset. A government stockpile of strategic and critical materials was established after the war, with about 100 different materials purchased for cash or obtained by trading US agricultural commodities for them. In the long term, the shortage of tin later led to the complete substitution of aluminum foil for tin foil and the substitution of aseptic packaging for polymer-lined steel cans and tin electroplated steel cans.

Resources change over time with technology and economics; More efficient recovery results in lower ore grade required. The average grade of processed copper ore has dropped from 4.0% copper in 1900 to 1.63% in 1920, 1.20% in 1940, 0.73% in 1960, 0.47% in 1980 and 0.44% in 2000.

Perspective: Of Climate Change, Taxes, And Socio Economic Development

In 1960, the Belgian Congo (the world’s only significant source of cobalt) was hastily neglected, the cobalt-producing province seceded into Katanga, several wars and rebellions, local government removals, and the removal of railroads left the cobalt supply in a state of flux. Destruction and Nationalization. The invasion of the province by Katangan rebels in 1978 disrupted supply and transport and briefly tripled the price of cobalt. Cobalt supplies were disrupted and prices soared, and nickel and other substitutes were pressed into service.

After this, the idea of ​​a “resource war” was popularized by the Soviet Union. More than the chaos caused by the Syrian cobalt situation, this is a strategy designed to destroy economic activity outside the Soviet bloc (Third World?) by acquiring vital resources through uneconomic means (military?). , keeping these minerals from the West.

An important way to avoid a cobalt situation or a “resource war” is to use substitutes for a material in its d-use. Some of the criteria for a satisfactory substitute are (1) availability in sufficient quantities domestically or from adjacent nations or possibly foreign allies, (2) having physical and chemical properties, performance, and longevity comparable to those of the first choice material, ( 3) well-established and known behavior and properties, especially as a constituent of foreign alloys, and (4) the ability to process and process with minimal changes in existing technology, capital plant, and processing and manufacturing facilities. Some suggested substitutions were alumina for bauxite, molybdenum and/or cobalt for nickel and copper alloy automobile radiators for aluminum alloy automobile radiators.

Materials can be removed without material substitutes, for example, by using high-tsion electrical discharges to shape hard objects previously shaped by mineral abrasives, providing superior performance at low cost.

An important method of replacing a resource is synthesis, for example industrial diamond and many types of graphite, but some forms of graphite can be replaced by a recycled product. Most graphite is synthetic, for example, graphite electrodes, graphite fibers, graphite shapes (machines or machinery) and graphite powder.

Another way to replace or extend a resource is to recycle materials from trash or waste. This depends on whether or not the material has been dissolved or remains a durable product that can no longer be used. Landfilling a durable product depends on its resistance to chemical and physical degradation, availability, availability, price, and ease of extraction from the original product.

For example, bismuth in stomach medicine is hopelessly dispersed (dispersed) and therefore cannot be recovered, while bismuth alloys can be easily recycled and recycled. A good example of where recycling makes a big difference is the availability of resources for graphite, where flake graphite can be obtained from a recyclable resource called kish, a steelmaking waste that separates the carbon from the malted metal into graphite in kish. .
