SOLAR DESALINATION PLANT: EVERYWHERE AND ANYWHERE

Solar desalination plant, California, Source: Cole Mellino, EcoWatch
Solar desalination plant and technique is simply to convert any salty water to usable water by solar energy. The seawater and solar available for desalination which can be used for drinking or agriculture or for industrial uses where saltiest water cannot be used. The Great Aristotle told this method during 4 BC, by heating and evaporating the non-potable sale water and vapor collected as potable water. Alexander the Great used the same technique during the voyage in ships during 200 AD.
Around the world, 125 countries are adopting solar desalination technology for drinking water and agricultural uses.
Middle East                                   53.5 %
North America                              17 %
Asian Countries                           10.7 %
Europe                                          10.1 %
Central and South America        02 %
Australia                                       0.5 %
Methods of Solar Desalination
The direct method, a distilling mechanism connected with a solar collector and in a simple cycle method, the salt water converted to usable water.
The second method, an array of solar collector consisting of photovoltaic and or fluid based thermal collectors and conventional separate desalination plant. The reverse osmosis [RO] and photovoltaic panels system available for commercial use from the year 2009 onwards. In the second method, water is cheaper when the production is increased. An average of 200 Liters water can filter in one square meter Photovoltaic panel processor in a day.  This method largely used for agriculture in arid countries and acute shortage of drinking groundwater countries. Around the world, 750 million people are not drinking or not using clean water at this stage. This may go up 1.9 billion in next 8 to 10 years.
Top Countries Using Solar Desalination
The top four countries using Solar Desalination drinking water around the world:
Largest Solar Powered Desalination Plant, Saudi Arabia, 
1.    Saudi Arabia – is the largest desalination water producer in the world and leader in this process for a long time. In Al Khafiji, the largest solar photovoltaic plant installed and working successfully in the Desert Nation. By 2019, Saudi Arabia wants to convert all its plant run by solar energy. In other words, shift towards solar desalination.
2.    Israel – the desert land is the pioneer in water conservation technology. The 80 to 85 % of the wastewater recycled in Israel. The country is planning to use recycled water minimum 55% for agriculture purpose. By installing, processing, and selling their solar desalination technology, 300 more companies earn nearly $ 2.5 Billion per annum.
3.    California – is one of the largest user and 17 plants installed in California. One of the largest independent water producers is WaterFX in California, making several initiatives and kind of researches to supply good water. California uses the water for agri-business and for commercial uses.
4.    South Asia – South India one of largest solar plant installed and produces 37 million cubic meters of water per annum in one plant, and the second plant produces 100 million liters of seawater. This is to mainly to take care of drinking and for commercial uses.
The initial cost is one of the worrying factors in these solar desalination processes. At the cost of USD 1.5 to 2.0 per cubic meter of water produced. The cost varies depending upon the technology used and output made. Israel’s Hadera plant make at a cost of USD 0.65 to 0.50.
Like Mobile towers, internet connection, the Solar Desalination Plants are inevitable in any country. Just planting one tree, one person, and one year will solve this problem. Green the earth and Green your life.

OVERVIEW OF FOSSIL FUEL AND FUTURE RESERVES


Fossil fuel is defined as fuel obtained from prehistoric organisms. It may be any fuel containing carbon that is derived from decomposed leftovers of plants and animals that have died thousands of years ago. Examples of fossil fuel include:
  • ·         Coal,
  • ·         Natural gas,
  • ·         Petroleum,
  • ·         Peat,

Crude oil (unrefined petroleum) has been the major source of oil over the years and being the major source of energy, it has been heavily exploited over the years. Crude oil is used as the source of fuel and energy for powering automobiles, machinery, residential homes and so forth.
The world’s reliance on crude oil comes with great cost. Primarily, oil is a hydrocarbon that contains high amount of carbon, thus when burnt, crude oil gives off carbon dioxide because its carbon content combines with oxygen and therefore, the resultant carbon dioxide is released into the atmosphere. Carbon dioxide is a colorless, odorless and tasteless gas that is a little heavier than air. Moreover, carbon dioxide causes global warming; it is a greenhouse gas. Global warming is one of the major issues faced by our planet and with the incessant burning of oil in automobiles and the projected increase, the world will likely face grave issue of global warming if nothing is done about it.
Furthermore, ozone depletion is a major issue caused by the burning of fossil fuel. The ozone layer is being gradually depleted, causing the amount of ultraviolet radiations reaching the earth to increase. These demerits are indeed grave, but no effective alternative to replacing crude oil has been developed. A lot of novel technologies are propping up as alternatives. However, these technologies are not yet mature to replace crude oil as a source of energy.
Natural gas is also an excellent source of energy, and there is even a higher deposit of natural gas than petroleum, but petroleum is still the dominant source of energy for several reasons. Crude oil accounts for more than 30% of the total energy needs of the world. This figure is above that of natural gas and coal. Crude oil can be refined into various forms such as diesel fuel, gasoline, kerosene and these sources of fuel are quite indispensable in the world today. Studies show that the global reliance on crude oil is not likely to change in the next 30 years.

We the habitats of this word need to think about our environment, future generations and natural blessings of God.

DEVELOPMENT OF SUPPORT SYSTEM MODEL FOR EFFECTIVE DECISION MAKING IN THE FOOD INDUSTRY

There is increased concern regarding global food safety in the present modern era. Irish pork incident that happened in 2008 caused the country-wide destruction of pork products and resulted in a fright of food borne illnesses throughout the northern global hemisphere. The Centers for Disease Control and Prevention has reported 76 million cases in which people suffered food borne disease every year. About 300,000 were hospitalized while about 5000 people died in the year 2009. The US Department of Agriculture has divined a continual increase in food-related diseases in the future. Therefore, it is vital for processed foods manufacturer to take mitigation strategies and framework during production and supply chain. Moreover, it is necessary to communicate the consumers or customers well in time to prevent them from diseases.
Many manufacturers forced to modify the entire production run of a particular product due to safety concerns. For instance, Peanut Corporation of America faced safety issues for their peanut butter by the year 2009. In the recent past, the Food and Drug Administration of the United States reported many incidents ranging from labeling to packaging errors having serious health hazards.
Effective management of processed food products in the context of safety has a great challenge for the industry as well as governments. Unhygienic and contaminated food products can make a potential threat for public health. This is imperative to evaluate existing safety challenges that may generate food borne diseases. The reliable knowledge management can facilitate decision-making during manufacturing of processed food. This all is possible by employing reliability engineering that is based on both qualitative and quantitative characteristics. The measurements of reliability is important for consumer requirements compliance that demands a state of art design in reliability to attain the goals. Reliability engineering emphasizes the significance of moral engineering principles to ensure the product reliability. Identification of possible causes of failure and eradication can help to improve product reliability.
In conclusion, the processed food industry has its unique set of hazards. It is overwhelmed by a long history of fatality and disease occurrence. The study emphasizes the importance of reliability engineering including knowledge management model within the supply chain of the food industry, effective communication and identification of steps to facilitate the industry. In addition, decision management model will enable the industry to overcome the product safety issues and incidents as well as rebuild trust among their customers.

CLIMATE CHANGE CLOSING THE GENDER GAP FOR VALERIAN PLANTS

Valerian plants are likely to grow in hot and cold mountain slopes depending on their sex. The growth of male’s valerian plants depends on heat and resultantly, global warming boosting their growth in the mountains of Colorado’s Rocky. The ratio of male to female plants changes with elevation because of males and females like dry and warm as well as cold and wet conditions, respectively. The female’s plants may probably account 80% in few upland sites, but the weather is becoming warmer on up slopes of the mountain due to climate change. Subsequently, more male’s plants are growing compared to females that is an indication of climate change
According to research conducted in the Rocky Mountains forty years ago, the number of males was one third compared to females which is on the increase with the passage of time. This shows that the warmer climate is lessening the females upside the mountains. The rate of change in male to female plants share has been changing equivalent to the magnitude of climate change since the late 1970s. The upslope area is going to dry due to the melting of snow and summers are becoming warmer. Resultantly, rainfalls and moisture of soil have been moving on the upside of the slope by 133m and 195m in every decade, respectively. Subsequently, the sex ratios of valerian plants and climate have become interlinked. Hence, the researchers can use this trend as a fingerprint to predict future scenario of the species’ population.Moreover, in 2011, the researchers observed a drastic increase in the share of males to females compared to the period of 1978-1980. This may eliminate flowers by destructing female’s plants in lower altitude. In short, the scientists have the opinion that migration due to climate change may set the geographical limits for only one sex of the plants.

ENVIRONMENTAL SECURITY ANALYSIS OF CAMBODIA IN PERSPECTIVE OF POPULATION DYNAMICS

1. Introduction

Cambodia has used the huge natural base asset to enjoy in building up the entire economic breakthrough but at the same time deteriorated the said resources at a greater rate of utilization. This reflects the lack of sustainability of the resources available in the state as compared to the levels of its population. Lack of proper management of the natural resources often results in the compromising of the long period economic threshold as well as conquering the poverty epidemic ("Global forest resources," 2010).
The states rural development is not as proportional comparing the public goods to the state of livelihoods as there is a decreased access and low quality that affects the poor population dearly. The people surviving below the poverty line are more prone to the frustrations of inadequacy of ownership of assets, life opportunities and are left to compromise with the changing and ever fluctuating climatic conditions of the state of Cambodia.

2. Overview of Current Challenges and Opportunities

The environment and climate change has come to be a priority concern of the government of Cambodia in the recent past, and it has been incorporated in the development schemes of the state's affairs. The studies and observations regarding the current situation showed that the government is committing itself in improving. He is addressing matters pertaining the environment and its conservation, demographic study and governance, human rights and the entire public education (Cambodia - European Community 2007; PSDA 2013).
The understanding of the environmental helps in shaping up an organism's life in the ecology. The parameters for coping in unstable areas are at stake because the survival rate depends on striving to survive as a result of improper provision of all what it takes to be an outstanding conqueror in the long run.

2.1 Environmental Concerns and Biodiversity

The most outstanding environment related security issues trending around the state of Cambodia includes the destruction and deterioration of the entire ecosystems, breakdown of the food supply chains, access to water supply, inadequate land use and poor government policies. Moreover, the issues are pertaining to the safeguarding of all the natural resources such as lack of the ability to utilize natural based products from the ecosystems and the outputs generated from the ecosystems such as forests and fisheries. There exist irresolvable disputes and high interests over resources that are scarce with the given high and rising population in the state of Cambodia. Lack of natural capital, pollution effects and the existence of conflicts over resources will be remained a newsmaker for the current situation.It may continue until proper guidelines on the empowerment of the unemployed and safeguarding of the natural resources are concerned (Dasgupta, Uwe, Craig & David, 2003. "Global forest resources," 2010).

3.0 Population Dynamics

The study of the interaction of mankind population change over a given period is known as population dynamics. It is a study that incapacitates all factors revolving around the human life including, age, birth and death rates, immigration and number of immigrants (Solbu, Engen & Diserud , 2013). Population dynamics is linked with social, economic and environment parameters that are integral for sustainable development. Figure 1 shows a graphical presentation of these parameters and their association with population dynamics. In this context, the human population trends are alarming in the state of Cambodia as they are increasing with a rapid growth rate and the available resources within the environment are constant. The entire population is of importance to the environment on both the positive and negative impacts that will be felt and seen later. The rising population in the Cambodia state is un-proportionally increasing the demands of the natural resources such as land adequacy, water availability and energy sourcing and supply.

Population dynamics exists in the context of persistent inequalities and a major influencing factor in the development process. This also incorporates the balance of growth and associated effects that would be seen in the coming years by the future generation.

3.1 Environmental Concerns & Population Dynamics

Key environmental issues related to population dynamics in the state includes land degradation, loss of biodiversity ecosystem, deforestation, scarcity and pollution of water, natural hazards as well as disaster and change in the climatic conditions. These environmental problems have effects on the vulnerability and poverty issues, economic development and public health (Cambodia - European Community 2007; Solbu, Engen & Diserud, 2013)..

4. Population Dynamics and Biodiversity

Implications and degradation of loss of biodiversity and services offered by the ecosystem are currently being felt on the ground by the residents. It is endowed with various natural resources, regimes of hydrology, and this diversified ecosystem provides resources and source of livelihood to the major part of the entire population. There lies a fishing viability in the course of rivers and lakes in the country, and the population of the country is dependent on it. Due to this increase in population, there is a decreased levels of productivity of the fisheries industry in regards of illegal and overfishing as well as the downgrading of the critical forest covers and exhaustion of the wetlands (Cambodia - European Community 2007). The fishery sector is not only on the lead for over-exploitation of the resources in Cambodia. There is a substantial lack of proper management with regards to matters of food security, the rights of humans and the basic social, economic needs which have a significant role to play in the country.

5. Population Dynamics and Pollution Effects on Environment

The forests cover of the land of Cambodia serves as a major source of many lives and ecosystem opportunities that entail climate control and regulation, water and air purification (Yusuf & Francisco, 2009). The forests are also in charge in the regulation of water flow to river basins such as the Mekong basins in the land of Cambodia. The rate of forest clearing and deforestation is still high as the total forest cover has decreased by over 15 % annually. Loss of forest cover downgrades the flexibility of the entire ecosystem to calamities as droughts, diseases and increased effects of climate change (Yusuf & Francisco, 2009). The accelerating factors to the decline in the forests cover in Cambodia is attributed to rising population and the need of resources such as sources of energy, shelters and settlement as well as infrastructural development. The increase in demographic pressure is in course as the residents are in need of more land for cultivation and pursuing their agricultural expansion. The poor planning and management of the current land allocation, as well as land grabbing by corrupt persons and officials in the departments of forestry and conservation, are also cause of concern. The state has a record of being one of the worst in the rates of deforestation (Dasgupta et al. 2003: PSDA 2013).
Deposition of silt, use of manure and fertilizer and practice of good agricultural practices are the surviving tactics of the Cambodia agricultural ventures. This is because the land of Cambodia is of low nutritional composition and fertility for crops to thrive. Low quantity and quality production of food crops have been attributed to the infertility of the soil (Yusuf & Francisco, 2009). Demographics or population dynamics has a direct and indirect cause to this issue at stake. For instance, land degradation is hugely influenced by soil erosion that is caused by deforestation and clearing of the soil cover thus leaching off all the soil constituents to the water- ways. This poses a huge problem to the entire population as the low yield in productivity raises the concern of food security, health of the entire population and adverse effects on land and water pollution (Yusuf & Francisco, 2009).
Pollution of water bodies is much attributed to the growing and high level of the population of residents. A good example is the Tonle Sap great lake where human settlement took course long ago, and they are now reclaiming parts of the shores to add more structures. This poses a huge risk to the entire population and the aquatic life such as fish. With increasing demand for processed products for the entire population, Cambodia has experienced an increased number of the industrial establishment which has had a great impact on the state’s economic (ADB, 2007: PSDA 2013).  On the contrary, there is inadequate control over the wastes produced by the manufacturers and processors. Most of the waste eventually discharged into the water bodies, and it poses a risk to the aquatic life. Discharge of waste water into water bodies is against the conduct of good business practice. In addition, lack of management and corruption of heads of such departments should be revoked off their working permits as they are helping in no way either man or the animal life in the water (Cambodia - European Community, 2007).
As the population scales to higher levels, there is the lack of income generating activities and this leads the people of Cambodia on the move to seek other applicable alternatives elsewhere that can facilitate them to acquire sustainability. This has brought about seasonal migration to and fro the neighboring countries for specific periods of time (ADB, 2007; PSDA 2013).
The environmental concerns in the country downgrade the value and access of the available resources and in the long run generates other health problems where the most affected are the poor persons. This increases the vulnerability and complications in the economic development and the fights against poverty. The present number of persons living below the poverty line is approximately 35%. (ADB, 2007: PSDA 2013). Even though, the standards of living have improved in the recent past but there is a continued widened gap between the rich and the poor. In Cambodia, because of the high population, poverty is not only inclined to the rural areas but also in the urban (Biddulph, 2012; Wingqvist, 2009). Urban poverty is on the rise with the increasing urban population. Agriculture, forests and fisheries in Cambodia serve as an income generating activity as well as assurances and provision of food security during the hard time. The poor Cambodians depend entirely on forestry, agricultural and fishery products for their daily living (Cambodia - European Community 2007).

5.1 Population Dynamics and Natural Calamities

Increased frequency of floods, rise in the level of sea water and widespread of common vector-borne illnesses is an impact of the changes in climate in the state of Cambodia. The major population makes all things impractical and impossible in combating various issues as fighting against diseases and protection against natural calamities like floods and drought. The institutions set aside by the government to fight against such risks, and natural forces remain limited and ineffective in their ability (Biddulph, 2012). The fishing communities of Cambodia are more vulnerable to the effects and impacts of the climatic changes. This is due to low possibilities of other income generating sources as there is no land available. In the case of availability, the high prices may not suit the demand by the poor as compared to the rich (Biddulph, 2012; Wingqvist, 2009).
In addressing the impacts and effects that come up with the population dynamics in ways that protect both the rights of mankind and at the same time protecting the natural environmental resources, various frameworks and formulation have to be set to address this issues. This demands to include involvement of all stakeholders in addressing and monitoring mechanisms to look into inequalities existing in Cambodia (ADB, 2007; PSDA 2013).
Securing resources to do planning and the utilization of the available data of the entire population will help a lot in the forms of allocation of resources by the government, foreign aids and other forms of dissemination that requires the availability of data at hand.

6. Conclusion

Population dynamics refers to the interaction of change in population change over a given period and is dependent on various factors including age, birth and death rates and so forth. Sustainability of a country's population is based on the available resources. Proper control and mitigation strategy regarding the planning and allocation of resources especially among a growing population becomes hectic for everyone. However for effective conservation and maintaining of the country's heritage, strict laws and regulations should be enforced to guard and protect it. The protection of forests and water bodies is also a significant advantage for the future generation.

THE BLESSINGS OF FASTING AND HOLY RAMADAN (RAMAZAN)

Holy Ramadan (Ramazan) is a religious practice involving fasting and separation unto God usually held on the ninth month of the Islamic Calendar. During the season, Allah expects the Muslims to demonstrate piety and this is achieved through fasting. It is ceremonially practiced among Muslims across the world. The beautiful thing about the Holy Ramadan is not just because it is an act of obedience to Allah but it carries with it a lot of benefits which faithful Muslims believe to obtain on fasting. Obviously, a lot of people would see fasting as futile efforts but it is obviously not. Holy Ramadan is obviously not a waste of time or energy; below are some of the interesting blessings you would obtain on fasting in Holy Ramadan.
-          Protection:
Muslims across the world rely on Allah for protection. Fasting in this holy season is one of the ways to obtain such blessing from Allah. This blessing comes with a number of packages including avoiding immorality, avoiding uproar, anger, avoiding stupidity and avoiding haram.
-          Taqwa:
Taqwa is one of the blessings a faithful Muslim should receive from Allah. It is not just a blessing but it encompasses a number of other blessings. Taqwa includes blessings like the fear of Allah, acceptance of little things that one has achieved, practice of the revelations from Allah, self-control, self-discipline, self-restraints, self-education and self-evaluation.
-          The revelation of the Holy Qur’an
Muslims across the world believe that the Holy Qur’an is an embodiment of a lot of blessings. Fasting in Holy Ramadan is an interesting avenue to obtain revelation.
Moreover, great joy comes from fasting.
-          The blessings of Sahoor:
Sahoor is a practice in Islam that has great significance. It implies late night meal and the meal is an avenue for Muslims to gain a number of blessings from Allah. Such blessings include Zikr, night prayers, recitation of the Holy Qur’an, remembrance and contemplation, Dua of Fajr and the Fajr Salat.
-          Itikaf which is translated “retreat” comes at the tail end of the Holy Ramadan. During the last ten days of the Holy season, Muslims are encouraged to hold retreat which allows them to enjoy a number of blessings from Allah. This includes untold blessings and rewards, contemplation, becoming better citizens of a country and peace of mind.

It is necessary to understand what fasting stands for in Islamism. Fasting comes from the Arabic word “sawn” which means “to refrain”. Thus, the Holy Ramadan is a season where Muslims refrain themselves from things that defile and keep themselves pure before Allah.

SUSTAINABLE SOLAR BUILDINGS BY USING SOLAR PANELS

Solar energy is a clean energy capable of generating electricity and heat for homes and industries. However, to effectively utilize solar energy, solar panels have to be installed to make solar buildings
design, especially at the rooftop. Solar panels, PVs, require large surface areas in order to accumulate enough solar power that would be used in powering the building when there is no sunlight. The intensity of sunlight varies and can be affected by a number of factors. This is why solar energy is not really a reliable source of energy but in some regions of the world prone to the high intensity of sunlight, solar energy comes handy. Moreover, solar PVs store solar energy to be used when it is mostly needed in solar buildings.
If supplying electricity and energy to the building is the only function of solar panels installed on rooftops, it would have been enough. However, solar panels do much more by reducing the amount of heat reaching the roofs by about 38%. This is especially useful in regions of the high intensity of sunlight. Studies have shown that the amount of heat reaching a building ceiling can be reduced by about five degrees Fahrenheit or three degree Celsius. Larger solar panels such as tilting panels, which provide a gap between the building and the solar panel making it possible for air to circulate, have even higher levels of cooling effects than flush solar panels.
Moreover, the cost can be saved as a result of the energy saving potential of solar panels. The cost that would have been spent on cooling the home or building can be saved. It is interesting to note that the cost saving the potential of solar panel is up to five percent discount of its cost. Cooling the building is not the only advantage of solar panels. During winter, solar panels come handy as they can be very helpful in holding heat at night in the building to help warm up the home. This is also an energy saving benefit of solar panels. The heat that accumulates in the building during the day is kept from escaping and, therefore, the home is warmed up.
Solar panels come handy as it offers benefit to the buildings and the environment. The energy saving potential of solar panels cannot be overstated. Moreover, they supply energy to the home. Solar energy is one of the best plans of actions on reducing the use of fossil fuels in homes and automobiles. Although the cost of solar PVs is high, their benefits are often commensurate to the cost or even surpass the cost. However, with the advancement in technology, the costs of solar PVs are expected to fall while their efficiencies in storing solar energies are expected to rise. If the expectations on solar energy is come through, it might as well effectively replace fossil fuel as a source of energy or perhaps go a long way to serve as an alternative. However, at the present most homes in the UK, up to half a million buildings, use solar panels.
