Answers
Resources can be classified in four categories on the basis of status of developement
- Potential resources
- Developed resources
- Stock
- Reserves
Differentiate between Potential and developed resources :
(i) The avalaiblilty of technology is there to extract potential resources but these resources have not been developed properly.
(ii) These resources are not been utilised.
(iii) Lack of awareness about such resources.
(iv) Quantity and quality of resources have not been determined.
(v) For example: Western part of india particularly Rajasthan and Gujarat have enormous potential for the development of wind and solar energy but so these are not been utilised due to lack of awareness.
(i) The avalaiblilty of technology is there to extract potential resources but these resources have been developed properly.
(ii) These resources are been utilised.
(iii) There's awareness about such resources.
(iv) Quantity and quality of resources have been determined.
(v) For example: Petroleum
Differentiate between Stock and Reserves :
(i) There is absence of technology to extract such resources and are called stock
(ii) People are not able to utilise because there's no technology to access such resources.
(iii) For example: Water is a compound of two inflammable gas ( hydrogen and oxygen) which can be used as a rich source of energy but we do not have the proper technology to use them for this purpose hence such resources are considered stock .
(i)There is presence of technology to extract such resources
(ii)Such resources are preserved for future use or used only to a limited extent and are called reserves.
(iii) For example: Water in dams ,forests etc. River water can be used for generating hydroelectric power but it is being only to a limited extent so that it can be used in the future
Explanation:
1. Differentiation between potential and developed resources:
Potential Resources:
- Potential resources refer to the resources that exist in a region and may be used in the future.
- They have the potential to be utilized and exploited with advanced technology or economic feasibility.
- These resources are not currently being used due to various constraints, such as lack of technology, infrastructure, or economic viability.
- The actual existence and quantity of potential resources are uncertain and require further exploration and evaluation.
- Examples of potential resources include undiscovered mineral deposits, unexplored oil reserves, or unutilized agricultural land.
Developed Resources:
- Developed resources are the ones that have been surveyed, evaluated, and are currently being utilized for various purposes.
- These resources have been explored, extracted, and made available for human use.
- Developed resources have undergone the necessary processes, such as extraction, refinement, and manufacturing, to convert them into usable forms.
- The quantity and quality of developed resources are known and can be measured.
- Examples of developed resources include cultivated agricultural land, operating mines, or established infrastructure like roads and buildings.
2. Differentiation between stock and reserves:
Stock:
- Stock refers to the total amount of a particular resource present in a specific region or globally.
- It represents the overall quantity of a resource available, regardless of its accessibility or economic viability.
- Stock includes both identified and unidentified resources, as well as those that have been discovered but not yet evaluated or exploited.
- It provides an estimate of the total potential of a resource but does not consider factors like extraction costs or technical feasibility.
- Stock can be thought of as the entire resource pool, including both reserves and undiscovered resources.
Reserves:
- Reserves, on the other hand, represent the portion of a resource that has been identified, evaluated, and is economically and technically feasible to extract.
- Reserves are the subset of stock that can be extracted using existing technology and at current market prices.
- They are the known and recoverable portion of a resource that can be economically exploited with existing infrastructure and methods.
- Reserves are typically classified into different categories based on their level of certainty and potential for profitable extraction, such as proven reserves, probable reserves, or possible reserves.
- Reserves are the economically viable portion of a resource that can be extracted and utilized in the present or near future.
In summary, potential resources refer to untapped resources with future usability, while developed resources are currently being utilized. Stock represents the total amount of a resource, including both identified and unidentified resources, whereas reserves refer to the economically extractable portion of the stock.
