Water conservation refers to reducing the usage of water and recycling of waste water for different purposes like domestic usage, industries, agriculture etc. This technical article highlights most of the popular methods of water conservation. A special note on rainwater harvesting is also provided.
Rainwater harvesting (RWH) considering as a technique system is being exploited of the variance topographic nature of the earth's surface, such as the use of valleys, depressions and oases , or through the berms or small dams from stone or cisterns building , to collect then reserve and store rainwater and floods during winter periods in various ways that differs in the purpose of collecting them depending on their rainfall rates and reuse when needed, whether for drinking, supplementary agricultural irrigation or to feed groundwater. Iraq in general and Nineveh Governorate in particular have been experiencing severe environmental conditions in the past two years, (2020/2021) & (2021/2022), and the most important of which is the rainfall lowing and the increasing demographic growth offset by significant water consumption, so as to ensure continued food production, increased irrigation projects have become urgent. Iraq is one of the countries that suffers from water scarcity in general and the amount of rainfall ranges (99.8 billion cubic meters/year) fluctuating and irregular distribution, so it requires investing this quantity and managing its use rationally by the system of rainwater harvesting .Northern of Iraq, including Nineveh Governorate is characterize by cereal winter crops production by depends mainly on rain fall to produce winter crops such as Wheat and Barley by rainfed agriculture method with rain requirements of more than (400mm/year), the rate of rainfall for a period (1970-2011) reached (170.3 mm/year).The rainy season in Nineveh Governorate extends from November to the end of May with fluctuating falls and small amounts that do not meet the needs of agricultural crops. This current study was prepared to activate the potential for harvesting rainwater for agricultural uses in the rain-fed areas prevailing in Nineveh Governorate. The agricultural system in semi-dry areas, including Nineveh Governorate, suffers from drought due to lack of rain and lack of yield in winter crops, including wheat and barley, which attracts the attention of researchers and stakeholders in finding a strategic solution to this problem, which lies in the activation of rainwater harvesting techniques, which is an integrated system for water management in rain lands in semi-dry areas to meet the lack of water need for agricultural crops. This system includes facilitating the flow of rainwater through canyons according to the decline of the land towards depressions, valleys and water basins prepared for this purpose to conduct supplementary irrigation with sprinkler irrigation techniques to activate the productivity of agricultural crops ,improve the performance capacity of rainfed farming systems, sustain green cover, reduce biodiversity extinction and address the problem of environmental drought to achieve agricultural sustainability.
Due to the ever-increasing population, surface water is not enough to meet all the demands and the dependence automatically goes to ground water that drastically leading to a constant depletion of ground water level causing the wells and tube wells to dry up. To enhance the availability of groundwater at specific places and times and utilize rainwater for sustainable development.
The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. Normally water is collected from the roofs of buildings and stored in rainwater tanks.
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. The harvested water can also be committed to longer-term storage or groundwater recharge.
"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.

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.

4. History
Around the third century BC, the farming
communities in Baluchistan (in present
day Pakistan, Afghanistan and Iran), and Kutch
(in present-day India) used rainwater harvesting
for irrigation.
Karez in Baluchistan
5. Rainwater Harvesting - Definition
Accumulating and storing of rainwater for reuse
before it reaches the aquifer.
Used to provide drinking water, water for
livestock, water for irrigation, as well as other
typical uses.
Rainwater collected from the roofs of houses
and local institutions can make an important
contribution to the availability of drinking water.
6. The climate in Pakistan
Pakistan is a predominantly dry country. The flat
areas in the south and centre have a desert-like
climate. May and June are the hottest months, when
it is 40 to 45 °C. The best travel period is from
December to March, when it is relatively cool. The
north of the country is visited by the monsoon in
July and August. In a short space of time a lot of
rain can fall and there can be heavy storms.
7. Importance of RWH in Punjab
The north Punjab areas Rawalpindi, Attock,
Jhelum and Chakwal natives rely on water
sources from rainfall and ground water. Pakistan
is known as an arid country having subtropical
climate and it may be divided into two regions.
1. Indus plain
2. Highlands
8. Dry climate is dominant in most of the country
parts except northern highlands. On an average
about 750mm of rain fall occurs annually in
northern areas. Baluchistan receives about
250mm of rainfall annually.
There is dire need to address the water shortage
issues across the country.
9. Need For Rainfall Harvesting in Urban
Areas of Punjab
Groundwater reservoirs have been declining in
urban areas due to rapid urbanization.
Excessive use of groundwater is causing
deterioration of water quality and drying up of
water wells.
The sweet water becoming scarce in urban
areas of Punjab Province.
Up-coning of deep saline water has started in
some parts of Punjab.
10. Name of city Faisalabad
Population( million) 2.83
11. There is a need to realistically estimate and
manage water resources for sustainable
development.
Storage of rain water on surface for future
use.
Recharge to ground water for sustainable
water supply in urban areas.
12. Rainwater harvesting techniques
There may be two rainwater harvesting
techniques for the accumulation of rainwater
that may be used for different purposes.
1. Land-based.
2. Roof-based.
13. Land-based
When the infiltration requirements of the soil have
been fulfilled and excess amount of rainwater flow
as overland flow and then become the runoff and this
runoff accumulated in reservoirs for agriculture
growth purposes, in ponds for recharging purposes
and in tanks for household, this type of rainwater
harvesting technique is called land-base.
14. Roof-based
The rainwater that falls on the top of the roof is
harvested for a domestic purpose, small scale
agriculture purposes and is also sometimes used
for drinking water because this water is usually
collected from clean surfaces. This type of water
harvesting is called roof-based water harvesting.
16. Factors affecting RWH system design
Rainfall quantity (mm/year)
Rainfall pattern
Collection surface area (m2)
Runoff coefficient of collection (-)
Storage capacity (m3)
Daily consumption rate (liters/capita /day)
Number of users
Cost
Alternative water sources
17.
18. RWH System Components
Catchment Area/Roof
- the surface upon which the rain falls
Gutters and Downpipes
- the transport channels from catchment
surface to storage
Leaf Screens and Roof washers
- the systems that remove contaminants and
debris
19. Cisterns or Storage Tanks
- where collected rainwater is stored
Conveying
- the delivery system for the treated rainwater,
either by gravity or pump
Water Treatment
- filters and equipment, and additives to
settle, filter, and disinfect
20.
21. Design considerations for rooftop
catchment systems
The material of the catchment surfaces must be
non-toxic and not contain substances which impair
water quality.
Roof surfaces should be smooth, hard and dense
since they are easy to clean and are less likely to
be damaged and shed materials into water.
Precautions are required to prevent the entry of
contaminants into the storage tanks.
22. No overhanging tree should be left near the
roof.
All gutter ends should be fitted with a wire
mesh screen to keep out leaves.
The storage tank should have a tight-fitting roof
that excludes light, a manhole cover and a
flushing pipe at the base of the tank.
The nesting of the birds on the roof should be
prevented.
23. A sloped bottom and a provision of a sump
and a drain are useful for collection and
discharge of settled grit and sediment.
Taps/faucets should be installed at 10 cm
above the base of the tank as this allows any
debris entering the tank to settle on the bottom
where it remains undisturbed, will not affect
the quality of water.
24. Design Consideration
An estimate of mean annual runoff from a given
catchment can be obtained using the equation.
S = R * A * C
Where
S = Rainwater supply per annum
R = mean annual rainfall
A = Area of the catchment
C = Runoff coefficient
Mean annual runoff
25. Catchment Area Size
Runoff depends upon the area and type of the
catchment over which it falls as well as surface
features.
Runoff coefficient for any catchment is the ratio of
the volume of water that runs off a surface to the
volume of rainfall that falls on the surface.
(C = V1/V2)
Type of Catchment Coefficients
Tiles 0.8 – 0.9
Corrugated metal sheets 0.7 – 0.9
26. Storage System
There are several options available for the storage
of rainwater. A variety of materials and different
shapes of the vessels have been used. In general,
there can be two basic types of storage system.
Underground tank or storage vessel
Ground tank or storage vessel
27. The choice of the system will depend on several
technical and economic considerations like, space
availability, materials and skill available, costs of
buying a new tank or construction on site, ground
conditions, local traditions for water storage etc.
Selection of System
28. Storage capacity
Knowledge of the rainfall quantity and
seasonality, the area of the catchment surface
and volume of the storage tank, and quantity
and period of use required for water supply
purposes is critical.
29. A better estimate of storage requirement can be
made using the mass curve technique based on
rainfall and water demand pattern.
Cumulative rainfall runoff and cumulative water
demand in year is calculated and plotted on the
same curve.
The sum of the maximum differences, on the
either side, between the rainfall curve and water
demand curve gives the size of the storage required.
