Natural Resources by-Dr. J. B. Kathiriyajbkathiriya
Natural resources are resources that exist without actions of humankind. This includes all valued characteristics such as magnetic, gravitational, and electrical properties and forces.
Biodiversity refers to “variety and variability among the living organisms and ecological complexes in which they occur”. This includes diversity within species, between species and of the ecosystem. It is defined as the totality of genes, species and ecosystems of a region.
Biodiversity or Biological diversity comprises Genetic diversity, Species diversity and Ecosystem diversity.
Physical & chemical evaluation of water jbkathiriya
Water sample is evaluated physically for colour, turbidity, odour, taste and electrical conductivity

he complete chemical examination of water in respect of its suitability or otherwise for drinking and for ordinary domestic uses normally includes determination of total solids, pH, hardness , free and albumoinoid ammonia, nitrate , nitrite, chlorides, and action on metals.
• It may also be necessary to examine waters for unusual constituents such as lead, zinc, arsenic, copper, iron, aluminium, magnesium, fluorides and cyanides, whose presence may be suspected from a consideration of the source of supply or from a history of toxic symptoms arising in man or animals drinking the water.
• Whilist the chemical examination and the interpretation of the results falls strictly within the province of the experienced analyst, some knowledge of the procedures involved will greatly aid the veterinary surgeon in appreciating the significance of the analytical findings.
• Total Solids
• pH value
• Hardness
• Chlorides
• The Nitrogen Constituents
• Reducing Powder or "Oxygen Absorbed"
• Natural Calamities like cyclones, flood, earthquake, volcanoes and landslides are normal natural events in the formation of earth, but they are disastrous when they strike human settlements.
• In India, natural disasters occur frequently . For example, about 260 million people are being affected by frequent floods which occur in eight major river valleys in 40 million ha..
• Drought affects nearly 86 million people 14 states including Tamilnadu.
• About ten million people are affected by cyclones in the entire 5700km long coastline of peninsular India in 9 states. This impact of earthquake is much more than the other disasters because about 400 million people in the seismic zones IV and V (55% of total area of India) are being greatly affected.
• About ten million people living along the entire sub Himalayan region and Western Ghats suffer a lot due to landslides. Since the disasters strike human settlements often in different parts of the world, they have to learn to minimize the effects of disasters.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
2. FoodResources
Food refers toanything eaten by man which gives
energy and which is able to meet physiological needs
for growth of humanbody
Today our food comes almost entirely from agriculture, animal
husbandry and fishing.
Although India is self-sufficient in food production, it is only because of
modern patterns of agriculture that are unsustainable and which
pollute our environment with excessive use of fertilizers and pesticides.
Importance of food
Food is a source of energy for man. It is used for
maintaining all body processes andactivities.
for physical and mentaldevelopment
for protection and regulation of bodyneeds.
3. Sources of food
Princeton societies obtained food mainlythrough
gathering and hunting.
Modern societies obtain foodthrough
cultivation throughagriculture
Domestication of animals
Fishing
World food supply
Ancient period : Through gathering andhunting.
Agricultural Revolution : with the application of
science and technology world food supplyincreased
remarkably.
4. Food security
It is the ability of all people at all times to access enough food for
an active and healthy life.
It is estimated that 18 million people worldwide, most of whom
are children, die each year due to starvation or malnutrition, and
many others suffer a variety of dietary deficiencies. The earth
can only supply a limited amount of food.
If the world’s carrying capacity to produce food cannot meet the
needs of a growing population then it will create problems.
Thus food security is closely linked with population control
through the family welfare program.
It is also linked to the availability of water for farming. Food
security is only possible if food is equitably distributed to all.
Many of us waste a large amount of food carelessly.
This eventually places great stress on our environmental
resources.
5. World food supply
It includes the adoptionof
Mixed farming
Good irrigation facilities
Control of soil erosion
Qualityseeds
Use of chemical fertilizers andpesticides
Good agricultural implements
Availability of storage and marketfacilities
Green Revolution : Resulted in remarkable increase in
food production which made a country self sufficient.
The quality of food alsoimproved.
6. World food Problems
Large Population - Inspite of green revolution it could
not meet the needs of growing population. agricultural
land got loot dueurbanization.
Energy : Farmers cannot afford fertilizersand
pesticides.
Land, weatherand climate : Agriculture is agamble on
climaticconditions
Absenceof food securitywhich dependson
food availability
purchasing power
7. Food Problems in India
The principle causes of food-shortage inIndia
• Want of improved methods of cultivationthrough
science and technology
• Poverty and lack of purchasingpower
• Tillers are not infeasts
• Excessive growth of population
• Lack of cold storagefacility
• Wastage of food for ignorance of preservingmethod
• Wastage of food in wrong process ofcooking
8. How to solve the food problem of India
• Introduction of improved method of cultivationbased
on science andtechnology
• Improvement of financial and educational statusof
Indian cultivators
• Balancing the demand withsupply
• Checking populationgrowth
• Increasing production of foodgrains
• Protection of food from rats, insecticidesetc.
• Judicious distribution of availablesupplies
• Proper publicdistribution
• Proper transportfacilities
9. Over Grazing
Live stock is an important source food in many
countries including India meat and milk are obtained
from live stock. Hence live stock less to be fed on
grazing lands.
Adverse effects of over grazing:
• Over Grazing Removes the Vegetation coverof the soil .
Plant population regeneration capacity islost
Exposes thesoil
Exposive leading to lessproduction
Leads to soilerosion
Leads towater infiltrationcapacityof soil

11. Effects of Modern agriculture
Modern agriculturerefers tocarrying on agriculturewith
the intensive use of irrigationfacilities,
chemical fertilizers, highyielding varietiesof qualityseeds,
pesticides and insecticides
modern form machinerywith aview toobtain higher
agricultural productivity andproduction.
It’s also called as greenrevolution.
Benefits of modernagriculture:
Contributed to high yields of agriculturalcrops.
Created awareness, interest among farmersfor
implementation of bettertechniques.
Improved income for thefarmers.
Rasied the standard of living of farmers.
Increased employmentopportunities.
Increased the economy of acountry.
12. Adverse impact of Modern agriculture
1. Fertilizer related problems.
Excessiveusageof chemical fertilizers lead toa micro
nutrient imbalance in the soil resulting in low
production.
Nitrogenand phosphorus used in agricultural fields is
washed off and released to the neighbouring water
bodies which causes eutrophication
2. Pesticide related problem.
Excessive usage of pesticides killed not only the
targeted pests and – insects but also non targeted
species which are useful foragricultural cropsand
ecosystem
Affected thequalityof food crops resulting in adverse
human health.
13. Adverse impact of Modern agriculture
3. WaterLogging
excess watergetsaccumulated in the fields due to
inadequate drainagefacilities
It is becauseof over irrigation of agricultural fields by
farmers.
Mechanical strength of water logged soil isreduced.
4. Salinity
Use of saline water forirrigation
Presence of excess salt in thesoil
Reduced cropproduction
5. Genetic diversity of Agriculturalcrops
