What Are The Affects On Health?

 

As globalisation increases, producers look to new markets. People in developing countries like Vietnam are becoming more educated and able to focus on quality including the food they eat. With the rising power of supermarket chains in developing countries replacing traditional markets for fresh fruit and vegetables, comes a demand for ‘clean and green’ produce. Consumers demand to know what pesticides and other chemicals have been used to produce their food. Consumers demand that crops are safe.

 

Access to fresh quality food is a cornerstone for building healthy nations. Where that access is lacking hydroponic farming can deliver clean, efficient solutions for rural and urban populations. Studies suggest that the nutritional composition of hydroponic crops may be equal or superior to traditionally grown produce.

 

Some have expressed health concerns about hydroponically grown food because of chemicals in the nutrient solutions that have been modified to be water soluble. But evidence continues to show that hydroponics enhances well-being.

 

One of the greatest advantages of hydroponics is its portability. Plants grow in specific conditions of temperature, soil nutrient content and light. That is why in areas where sunlight is abundant and water is scarce, hydroponic systems are extensively used. The eco-friendly system reprocesses the water it intakes, conserving water that would disappear in soil-based agriculture.

Another great health benefit is the fruit and vegetables are completely pesticide free, as insects can’t enter the controlled greenhouse environment. Nor can hydroponically grown food contain bacterial contamination from animal manure. Even organic produce can be affected by bacterial contamination so hydroponics provides protection against food poisoning and the taste is just as good.

 

Benefits for farmers

 

With changing conditions like global warming, rising sea levels, floods, cyclones and salinity, farmers who adapt to new forms of agriculture will benefit.

 

In its quest for sustainable development, Vietnam is dealing with socioeconomic problems, high rates of unemployment and low wages, while contending with natural disasters like the annual typhoon season. Natural disasters destroy farmland and livelihoods. Small amounts of government relief help but are not enough to restore prosperity to farmers, so one disaster or one big flood can set rural communities back for years.

 

The cost of floods both human and economic are constant realities in central Vietnam. Damage to dwellings, roads, bridges, machinery, embankments, water supplies, wells, businesses, livestock, farms and fisheries have a direct impact on the national economy, stymying growth.

 

For a long time, urbanization of the countryside was a popular measure of economic development, but in recent times there has been a rethink about the path to progress. The environment has suffered from development and rising sea levels threaten the Mekong Delta.

 

In April 2008, United Nations (UN) Secretary-General Ban Ki-moon issued a warning that price increases in food are being felt across the world. The UN's position was that hydroponics could provide a source of plentiful, healthy food as the world population grows. Hungry countries could use hydroponic farming to increase production.
