Natural Resources

---

Various types of resources are found in nature, the basic source of their creation is nature and all of them get established in a new form due to human influence. In this way, nature creates resources for humans which humans make usable through their efforts, desires and technical skills, but its actual physical basis is provided by nature. Man strengthens the economic system by exploiting resources from his environment. He keeps changing the physical environment which depends on his interest, skills and powers. But there is a limit to the change in the natural environment by humans, beyond which, instead of creation of resources, their decline begins.

The word ‘Resource’ which is made up of two words Re and source which mean Re = long term or again and source = means or solution respectively. That is, those resources available in nature on which a biological community can depend for a long period and which have the capacity to replenish or rebuild.

Norton S. Ginsburg said that “When the substances freely provided by nature are covered by human activities, they are called natural resources.”

According to Gaudí, “The human usable components of the natural environment are called natural resources.”

Thus, on the basis of continuity or continuity of use, Natural resources can be divided into three categories –

1. Renewable resources –
   • All those resources come under this category which can be re-produced.
   • For this, physical, mechanical and chemical reactions are adopted, hence these resources are inexhaustible and their life-sustaining re-use is possible.
   • Example– solar energy, wind, water, soil, agricultural produce and human resources.
2. Non-renewable resources –
   • These are such resources in the category of sustainable use of resources which cannot be replenished once they are exploited.
   • Their quantity is limited and the period of formation is also long.
   • Hence, if the resources of this category are exploited at a fast pace, they get exhausted.
   • Mineral resources present in the earth’s crust come under this category.
   • Example- petroleum, natural gas, copper, bauxite, uranium, thorium etc.
3. Recyclable resources –
   • Some such resources are found on the earth which can be used again and again.
   • For example, water resources are used in different forms at different times. Similarly, iron is also used in different forms.

Earth was earlier called the water planet because it is the only planet in our solar system where water is available in abundance. Water is used as raw material in various construction processes. It is an important environmental component. Along with this, it is a very rich medium in which things dissolve easily and it has been helping the animal world to maintain its existence from the origin of life on earth till today. Water has been known as a resource by the human world since the distant past and we will study it as an essential element for the support of life. In this we will analyze various traditional methods of water conservation by human societies. The pattern of water use by various civilizations of the world is constantly changing with technological development as well as more appropriate allocation of water. At the same time, our attention has also been drawn to the concern arising from the increasing demand for water in these various developmental activities. Along with this, the subject related to the historical perspective of water rights as well as the theoretical proposition or problem related to it have been examined in this unit.

Water – A resource

Water is one of the most essential resources on Earth, vital for all forms of life. Water is indispensable for life and development, making its sustainable management a global priority. Here’s a brief overview of water as a resource :-

1. Types of Water Resources

Water: Properties and Distribution

Water resources are essential for life and have unique properties and distribution patterns on Earth. Here’s an overview:

1. Properties of Water Resources
   • Chemical Composition: Water (H₂O) consists of two hydrogen atoms bonded to one oxygen atom. This simple structure gives water its unique properties.
   • States of Matter: Water exists naturally in three states: solid (ice), liquid (water), and gas (water vapor).
   • High Specific Heat: Water can absorb a lot of heat before its temperature rises significantly. This property helps regulate Earth’s climate and temperature.
   • Surface Tension: Due to hydrogen bonding, water has a high surface tension, allowing it to form droplets and enabling insects to walk on its surface.
   • Solvent Properties: Water is known as the “universal solvent” because it can dissolve more substances than any other liquid, which is crucial for biological processes and nutrient transport.
2. Distribution of Water Resources
   • Global Distribution:
     • Oceans: About 97% of Earth’s water is in the oceans, making it saline and not directly usable for drinking or irrigation.
     • Freshwater: Only about 3% of Earth’s water is freshwater. This includes:
       • Ice Caps and Glaciers: Approximately 68.7% of the world’s freshwater is locked in ice caps and glaciers.
       • Groundwater: Around 30.1% of freshwater is found underground in aquifers.
       • Surface Water: Rivers, lakes, and reservoirs hold about 0.3% of the freshwater.
       • Atmosphere: A small fraction of water is present in the atmosphere as water vapor.
   • Water Cycle:
     • Evaporation: Water from oceans, lakes, and rivers turns into vapor and rises into the atmosphere.
     • Condensation: Water vapor cools and forms clouds.
     • Precipitation: Water falls back to Earth as rain, snow, sleet, or hail.
     • Infiltration and Runoff: Water soaks into the ground to replenish aquifers or flows over the surface to rivers and lakes.

Understanding the properties and distribution of water resources is essential for managing this vital resource effectively.

  • Ancient Periods:
    • Community-Based Management: In ancient India, water was considered a common resource managed collectively by communities. Village assemblies (sabhas) and local councils (panchayats) played key roles in overseeing water distribution and maintenance of water bodies such as tanks, wells, and canals. These assemblies had the authority to resolve disputes and ensure equitable distribution.
    • Customary Rights and Riparian Principles: Rights to use water were generally tied to land ownership and proximity to water sources, following riparian principles where those owning land adjacent to water bodies had primary access. However, usage was regulated to ensure that downstream users were not deprived.
    • Sacred and Social Value of Water: Water was often regarded as sacred in Indian culture, and religious beliefs influenced water rights. For example, rivers like the Ganges were revered, and access to such water bodies was often considered a communal right, with temples and religious institutions playing a role in water management.
    • Construction of Water Bodies: Rulers and local chieftains sponsored the construction of stepwells, tanks, and other water bodies as acts of public welfare, and in return, these structures often came with communal rights attached. The construction of these water bodies often included explicit agreements on maintenance and rights of usage among local communities.
  • Medieval Period:
    • State Control and Royal Patronage: During the medieval period, especially under rulers like the Cholas in South India, the state began to exert more control over water resources. Rulers constructed large irrigation systems and asserted rights over rivers and water bodies, although community management and customary rights still played a significant role. Kings and local rulers often funded the construction and maintenance of water structures, ensuring water availability for agriculture and drinking.
    • Mughal Period: Under the Mughal Empire, the state’s role in water management became more pronounced, with the construction of canals and other irrigation works under state supervision. However, local customs continued to influence water rights at the community level.
  • Colonial Period:
    • Shift to State Control: The British colonial administration significantly altered traditional water rights and management systems. The British introduced centralized control and large-scale irrigation projects, such as canals in Punjab, to boost agricultural production. This often undermined traditional, community-based water management systems.
    • Land Revenue Systems and Water Rights: The introduction of land revenue systems like the Permanent Settlement linked water rights to land ownership formalized under colonial laws, disrupting the earlier community-based systems. This shift also led to the marginalization of traditional water users, such as pastoralists and fisherfolk.
    • Codification of Water Laws: The British codified water laws, which formalized the state’s ownership and control over surface water resources, sidelining customary and communal water rights.
  • Post-Independence:
    • After independence, the legacy of colonial water laws continued to influence India’s approach to water rights, with the state retaining significant control over water resources. While modern water laws began to develop, they often had to contend with the deeply entrenched customary practices and local traditions that had historically governed water rights.
• Community and Indigenous Rights
  • Marginalized Groups:
    • The right to water is particularly crucial for marginalized groups, including Dalits and Adivasis, who often face discrimination and lack access to clean water. 
    • Efforts are being made to ensure their water rights are protected and enforced.

Energy Conservation

Energy conservation is the practice of reducing energy consumption through efficient use and mindful behavior. It is not just about saving energy but also about optimizing resources to create a sustainable future. With growing concerns over climate change, resource depletion, and rising energy costs, energy conservation has become a critical issue globally. This essay explores the importance of energy conservation, its methods, benefits, and the role individuals and governments play in promoting it.

1. Methods of Energy Conservation
   • Energy-Efficient Technologies: Innovations in technology play a significant role in conserving energy. Energy-efficient appliances, such as refrigerators, air conditioners, and light bulbs, use less energy to perform the same functions as their less efficient counterparts. Smart home systems, which automatically adjust lighting, heating, and cooling based on occupancy, also contribute significantly to energy savings.
   • Building Design and Insulation: Buildings are major consumers of energy, primarily for heating, cooling, and lighting. Improved building design, including better insulation, energy-efficient windows, and the use of renewable energy sources like solar panels, can drastically reduce energy consumption in residential and commercial buildings.
   • Transportation Efficiency: Transportation is another major energy consumer. Energy conservation in this sector can be achieved through fuel-efficient vehicles, electric cars, public transportation, carpooling, and cycling. Reducing vehicle use not only saves energy but also reduces air pollution and traffic congestion.
   • Behavioral Changes: Simple actions, such as turning off lights when not in use, unplugging devices, reducing water heating temperatures, and using appliances during off-peak hours, can collectively make a significant impact on energy consumption. Public awareness campaigns can help educate individuals about these small but effective measures.
   • Industrial Energy Conservation: In industry, energy conservation can be achieved through optimizing manufacturing processes, using energy-efficient machinery, and recovering waste energy. Companies can conduct energy audits to identify areas where energy use can be reduced.
2. Benefits of Energy Conservation
   • Environmental Benefits: By reducing energy consumption, we lower greenhouse gas emissions and other pollutants, leading to improved air quality and a healthier environment. Energy conservation also helps preserve ecosystems that might otherwise be disrupted by mining, drilling, and other energy-related activities.
   • Economic Benefits: Energy conservation leads to cost savings for consumers and businesses alike. It reduces the need for expensive energy infrastructure, such as new power plants or grid expansions, which can have high economic and environmental costs.
   • Enhanced Energy Security: Reducing energy consumption decreases reliance on imported energy sources, thereby enhancing national energy security. This is particularly important for countries that import large quantities of oil and gas.
   • Improved Quality of Life: Energy conservation can lead to more stable energy prices, reduced air pollution, and a healthier living environment. It also encourages innovation and can create jobs in industries related to energy efficiency and renewable energy.
   • Resource Management: Fossil fuels like coal, oil, and natural gas are finite resources. Energy conservation helps extend the lifespan of these resources, ensuring they remain available for future generations. It also reduces the need for new energy infrastructure, such as power plants, which often have significant environmental footprints.

   • Technological Limitations: While many energy-efficient technologies are available, they are not always accessible or practical for all applications. Continued investment in research and development is needed to improve the performance and affordability of these technologies.

Metal and Mineral resources in India

---

India is endowed with a vast and diverse range of mineral and metal resources, making it one of the world’s leading producers of key minerals. These resources play a crucial role in the country’s economic development, industrial growth, and infrastructure expansion. India’s mineral wealth includes a variety of metallic minerals such as iron ore, manganese, bauxite, copper, zinc, and gold, as well as non-metallic minerals like limestone, mica, and gypsum. The mining and extraction of these resources are fundamental to various industries, including steel, cement, aluminum, and energy, which are the backbone of the Indian economy.

The country’s geological diversity and favorable geological settings have resulted in the distribution of minerals across several regions, with major deposits found in states like Odisha, Jharkhand, Chhattisgarh, Rajasthan, Karnataka, and Gujarat. The mining sector in India is a significant contributor to GDP, providing employment to millions and supporting downstream industries.

India’s strategic location also allows it to serve as a hub for exporting minerals to other countries, further enhancing its economic prospects. However, the extraction and utilization of these resources must be balanced with environmental considerations and sustainable practices to ensure the long-term availability and responsible use of these valuable assets.

Metal Resources

Metallurgy is the oldest of the applied sciences. Historically, its traces can be traced back to 600 B.C. when it was in its infancy. However, to understand the picture of the process of metallurgy, it would be useful to know the relationship between man and metals. At present, there are 86 metals that we know about. Before the 19th century, only 24 of these metals were discovered and out of these 24, 12 were discovered in the 18th century. Thus, from the discovery of the early metals gold and bronze to the end of the 17th century, only 12 metals could be discovered. Out of these, four metals, Arsenic, Antimony, Zinc and Bismuth were discovered in the 13th and 14th centuries, while Platinum was discovered in the 18th century. The other seven metals are known as archaic metals and are the basis of all early civilizations. These seven metals are as follows in the order of their discovery:

1. Gold
2. Bronze
3. Silver
4. Lead
5. Tin
6. Iron
7. Mercury

Some of these metals were known to Harappan, Mesopotamian, Egyptian, Greek and Roman civilizations. Five of the seven can be found in their native regions, for example, gold, silver, bronze, iron (obtained from meteor showers) and mercury. However, these metals were not found in abundance and the first two of them – gold and bronze – were widely used.

• Gold
  • In ancient times, gold items were found in abundance, especially in the form of jewellery. Gold can be easily converted into flakes and wires. So, based on this knowledge, man learned to convert gold metal into jewellery.
  • Since this metal is very soft and malleable, it can be used only for ornamental purposes and has no other use.
  • Another characteristic of gold is that it is not a corrosive or discoloured metal, so it serves this purpose very well.
  • Gold is widely scattered on the surface of the earth and is obtained from two types of deposits– in the form of deposits, which are found in solid rocks and are extracted from mines by traditional mining techniques and placer deposits, which are deposited in gravels and pebbles and are found in the beds of rivers and are obtained by cutting lode deposits.
  • Since gold is found as an alloy, goldsmiths in ancient times used to collect small pieces of it from river beds etc. and join them together by crushing them.
  • Gold became a rare and valuable metal due to mankind’s fascination with the colour of heaven and as a result it came into the category of precious metals in everyday life.
  • In the early stages of metallurgy, all metals were transformed by carbon or hydrogen, so most metals were not available in their pure form once smelted. The history of refining gold i.e. separating it from silver is very old. In the second millennium BC, the process of mixing molten lead with crushed quartz was used to separate the metal by grinding it.
• Bronze
  • The use of bronze is more important than ancient gold because bronze was used in the making of tools, implements and weapons in the beginning.
  • Evidence of the making of artistic objects by melting bronze, such as rings, bracelets, chisels, has been found in the Nile Valley till 3600 BC.
  • Its use is found in abundance in the making of weapons and tools till 3000 BC.
  • Malachite, a green brittle stone, was the source of bronze for the early smelters.
  • It is more likely that the initial bronze was obtained by the ancient potters through the furnace used for baking utensils because its temperature is 1100° to 1200°. If Malachite is put into these furnaces, bronze nuggets can be obtained easily.
  • Although the first smelted bronze was found in the Nile Valley, it is believed that this bronze was brought to Mintra by Garjiyan and smelted bronze was first found in West Asia between 4000 and 4300 BC.
• Copper (Mixture of Tin and Bronze)
  • Pure copper is rare. In fact, the Sumerians discovered in 1000 BC that if two different raw metals were mixed together in the smelting process, a different kind of bronze could be produced that was easier to flow. This mixture was stronger and easier to cast.
  • An axe head from 2500 BC was found to contain 11% tin and 89% bronze. This was actually the discovery of copper.
  • Copper was a more useful metal than bronze. It could be used to make agricultural implements and weapons, however, tin had to be discovered to make the metal of choice.
  • Tin does not occur in nature in its natural form.
  • The first tin-made artifacts were found in Western Asia in 2000 BC, however tin smelting was not common until 1880 BC. It was only then that it became popular in Western Asia.
  • Tin was transformed by charcoal and was initially thought to be a form of lead.
  • Both tin and lead were referred to by the Romans as Plumber.
  • Tin was referred to as Plumber Candidum and lead as Plumber Nigrum.
  • Tin was rarely used in its natural form and was usually alloyed with bronze to form copper.
  • The most common form of tin as a raw metal is oxite cassiterite. By 1400 BC copper had become the most dominant alloy.
• Silver
  • Although silver was found naturally, it was rarely found.
  • Silver is the most chemically active metal among the noble metals and is harder than gold and softer than bronze.
  • It comes second to gold in terms of ductility and malleability.
  • It is generally stable in clean air and water, but when it comes in contact with oxygen, hydrogen and sulphur, it becomes discoloured or tarnished.
  • Due to its softness, it is used in jewellery and is also a measure of wealth. In a way, silver can be prepared easily like gold.
  • Galena (lead ash) always contains a part of silver and it has been found that if lead is oxidised in the form of a powder, a drop of silver will definitely remain in it.
  • Another change in this process came about due to the discovery that if lead oxide is added to bone ash, it will dissolve in it and most of the material can be prepared.
  • By 2800 BC culling became a common method of producing silver.
• Iron
  • In ancient times, iron was obtained in very small quantities from meteorites. This natural iron could be easily identified because it contained nickel.
  • Hematite, the oxide form of iron, was widely used in ancient times for making beads and jewellery. It could be easily transformed or changed by carbon. However, a temperature less than 700-800 C is not suitable for forging, for this the temperature should be above 1100°.
  • Iron was first known to man in the form of wrought or wrought iron. It is a very interesting fact that iron was five times more valuable than gold and it was used for jewellery.
  • Iron weapons revolutionized warfare and iron tools and implements revolutionized agriculture.
  • Iron and steel became the building blocks of civilization.
  • An iron pillar of 400 A.D. still stands in the Qutub Minar complex, Delhi. It is made of wrought iron and rusts very little.
  • Iron is very rare to find in its natural form.
  • There is only one known source of iron which is in Greenland where iron is found in the form of lumps in the basalt and these lumps come out of the surface of coal which are a mixture of very rare nickel iron.
• Lead
  • Lead is not found freely in nature, but galena (lead sulphide) was used by the ancient Egyptians as eye paint.
  • Galena has a metallic appearance and hence it must have attracted the attention of ancient metallurgists.
  • The production of metallic lead from raw metal must have been relatively easy and in the absence of lead it could be made by converting galena. The melting point of lead is 327°C, so it can be flowed and stored in the furnace even at the lowest temperatures.
  • Initially lead was not widely used because it was very ductile.
  • The first use of lead is known to have been around 3550 BC.
  • Lead is highly malleable, ductile and indestructible, hence it is a very useful material for pipers. Many lead piper bees bearing the emblems of the Roman kings can still be found today.
  • Lead can also be flowed and collected from the bottom of the fire. This is an important process for this metal.
• Mercury
  • Mercury was known in ancient times and has been found in Egyptian tombs dating back to 1500 and 1600 BC.
  • The Roman historian Pliny outlined a method for cleaning it by squeezing it through leather. He also stated that it is poisonous.
  • Mercury, also known as quick silver, is the only metal that is molten at room temperature.
  • Although it can be found naturally, the most common ores it is found in are Calomel, Livingstonite, Cordierite and its sulphide Cinnabar.
  • It can be easily extracted by distillation as mercury decomposes at moderate temperatures and is volatile.
  • Mercury is widely used because it dissolves gold and silver (alloys) and is the basis for many plating techniques. There are also indications that it was an expensive item and was probably worshipped by the Egyptians.

India

The history of metal use in India is rich and spans several millennia, reflecting advancements in technology, trade, and cultural practices. Here’s a broad overview:

• Early Beginnings (3000–1500 BCE)
  • Bronze Age (Indus Valley Civilization): The Indus Valley Civilization (circa 3300–1300 BCE) was one of the earliest cultures to use bronze, a copper-tin alloy. They created tools, weapons, and intricate jewelry, and their metallurgical skills were highly advanced for their time. The famous bronze sculpture of the “Dancing Girl” from Mohenjo-Daro is an example.
• Vedic Period (1500–500 BCE)

Mineral Resources

To classify a ‘pure’ mineral as a mineral, the element must be solid and crystalline in structure. It must also be inorganic, naturally occurring and a homogeneous or homogenous element. Minerals that do not meet this definition, even though they have a defined chemical composition and are homogeneous, are sometimes classified as Minoraloids. The internal structure of a mineral is crystalline, with an algebraic spatial arrangement of molecules in an orderly fashion. This crystalline structure is based on regular internal atomic or ionic arrangement, which is the case with most minerals. Even when the mineral crystals are too small to be seen or have a crude structure, the crystalline structure can be determined by X-ray analysis and/or optical microscopy.

A mineral can be defined both in terms of its chemical and crystalline structure. In fact, two or more minerals may have the same chemical composition but their crystalline structures, also known as polymorphs, must be different. Similarly, some minerals may have different chemical composition but the same crystalline structure. The crystalline structure significantly affects the physical properties of minerals. For example, diamond and graphite are similar in properties because both are pure carbon but graphite is very soft while diamond is the hardest of all minerals.

A mineral is a naturally occurring substance. An inorganic substance is an organic substance with a definite chemical composition and a crystalline structure. A rock is a group of two or more minerals (a rock may also contain organic remains). A particular mineral in a rock may vary considerably. Some minerals, such as quartz, mica or feldspar are common while others occur only in one or two places in the world. More than half of the minerals are so rare that only a few specimens of them are known, and most are known by only one or two particles.

There are currently about 4000 known minerals according to the International Mineralogical Association, which is responsible for the recognition and nomenclature of minerals found in nature. Minerals may be classified on the basis of their composition. The list given below is arranged according to their bulk abundance on the earth’s surface :-

1. Silicate Class – Feldspars, quartz, olivines, pyroxenes, amphiboles, garnets and mica;
2. Carbonate Class – lime dolomite stalactites and stalagmites;
3. Blue Vitriol or Sulfates – anhydrite (Calcium Sulfate), Celestite (Strontium Sulfate), barite (Barium Sulfate and gypsum Chydrated Calcium Sultate, Sulfate class also includes chronate, molybdate, selenate, sulfite, tellurate and tungstate minerals;
4. Halide Class – fluoride, chloride and iodide minerals;
5. Oxide Class – hemetite, magnetite, chromite, rutile and ice
6. Sulfide Class – selenides, tellurides, arsenides, antimonides, bismuthimides and sulfosalts;
7. Phosphate Class – Phosphate, arsenate, vanadate and antimonite.

Minerals are most commonly used by humans as food. They are inorganic compounds that are essential for life and good diet. Some of these are: Minerals are salt; others include potassium, calcium, iron, zinc, magnesium and bronze. These can be obtained naturally through food or added as minerals or as trace elements. For a long time, humans have been adding these minerals to their food based on experience.

With the advent of metal technology, complexity entered the process of living. For example, the question arose as to who would have control over this new technology because those who were making these art objects were not necessarily the same people who were in power.

In most civilizations, copper technology brought with it scripts, which led to the beginning of a new chapter in the historical development process. If the advent of copper is the starting point of a new chapter in the stratification of social relations, iron provides the entry of tools for dwelling in new territories that were not yet inhabited. As a result of the process of expansion of agriculture, new and more capable tools were obtained. With its advent, not only did tools for cutting forests become available, but it also became possible to use them for exploring the hidden possibilities inside the land and for draining rivers. Similarly, minerals also have an important place in food supplements and ornaments.
