Natural resources can be a substantial part of a country's wealth; [7] however, a sudden inflow of money caused by a resource extraction boom can create social problems including inflation harming other industries ("Dutch disease") and corruption, leading to inequality and underdevelopment, this is known as the "resource curse".
Class IX – Repair parts and components to include kits, assemblies, and subassemblies (repairable or non-repairable) required for maintenance support of all equipment. Class X – Material to support nonmilitary programs such as agriculture and economic development (not included in Classes I through IX).
Diagram as published by McKelvey in 1973 [1] Diagram as published by McKelvey in 1976 [2]. A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery.
Natural resources are resources that exist without actions of humankind; this includes characteristics such as magnetic, gravitational, and electrical properties and forces. Resources may be classified as renewable or nonrenewable .
Natural resources are derived from the environment. Many natural resources are essential for human survival, while others are used to satisfy human desire. Conservation is the management of natural resources with the goal of sustainability. Natural resources may be further classified in different ways. [1] Resources can be categorized based on ...
Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, indicated and measured as categories. Inferred Mineral Resource is the part of a mineral resource for which quantity, grade (or quality) and mineral content can be estimated with a low level of confidence. It is inferred from geological ...
Classification and management of natural resources such as minerals and petroleum are classified using differing schemes. [4] [5] In 1997, UNECE published the United Nations Framework Classification for Reserves and Resources of Solid Fuels and Mineral Commodities (UNFC-1997) as a unifying international system for classifying solid minerals and fuels.

Soil texture triangle showing the USDA classification system based on grain size Map of global soil regions from the USDA. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
