Hydroponic Technology: Soil-less Cultivation to secure the Future of food

The global hydroponics market is projected to reach USD 395.2 million by 2020, at a CAGR of 16% from 2015 to 2020.

With increase in population, the demand-supply chain in India is strained. Due to constant change in economic and social structure, the supply food is under threat. Researchers have found out a tool that leads to soil-less cultivation, which will secure the future of food. Bahrain-based K.V. Bhaskar Rao, CCA, American Society of Agronomy spoke to NewsGram sub-editor Deepannita Das over Skype to explain how hydroponic technology has become blessing in the field of agriculture.

  • Agriculture in India is a 370 billion dollar sector– but there is little use of technology to improve its productivity. Around 2 billion dollars of fruit and vegetables are wasted because of lack of supply chain management and cold storage facilities and 40% of it gets wasted in transit, according to 2014 reports.
  • India has approximately 8000 refer trucks capable of transporting fresh produce. Food inflation in India is growing at 7%, due to supply demand mismatch. This inflation translates into an additional 70,000 crore rupees opportunity.
  • According to the data collected in 2010, India uses 91% of available water for irrigation and livestock, 2% for Industry and 7% for municipalities. Out of this, 49% of water is used from ground water sources and by this excessive exploitation water table is receding at 3 to 10 feet per year.

The food services market in India was estimated at $48 billion in 2013 in a study by the National Restaurant Association of India and Technopak. In five years, that could be worth $78 billion – that is nearly what the Indian IT industry currently exports.

  • While volumes are picking up, restaurant owners are looking to cut import bills and chefs are exploring ways to reduce the carbon footprint of the dishes they create. Air transport of food implies higher energy consumption resulting in carbon emissions.

Exotic lettuce grown in India could be 30 per cent cheaper than the imported ones. Imported cherry tomatoes can cost Rs. 1,000 a kg whereas the domestically produced ones could be priced at Rs. 200.

  • Demand-driven exotic vegetables production is suitable for the farmers as they have assured market through contract with consumers. Exotic vegetable market is growing at the rate of 15 to 20% per annum is increasing day by day since India is importing more than 85% exotic vegetables.

Cities like Delhi, Bangalore and Pune are practicing soil-less cultivation in large farms. Apart from that people in other cities are going for roof tops to do the same, said Bhaskar.

Here, the concept of Hydroponics and Controlled environment agriculture comes into play.

The science of hydroponics refers to the process of growing vegetables or fruits, without using actual soil. Despite the fact that all plants grow in soil naturally, it’s actually not the best environment for them.

THE METHOD-

Hydroponics is broadly classified into two main categories based on the growing medium:

  1. Solution Culture: this system employs various techniques of growing. It may be Static, continuous flow (NFT = Nutrient Film Technique), Ebb & Flow, DWC (deep water culture), Aeroponics, Fogoponics, rotary etc.
  2. Medium culture: this system uses an inert porous medium and is termed as passive Hydroponics. Media may be like gravel, Perlite, rock wool, coco peat/husk etc.

 Adjiedi Bakas, the Dutch trend watcher, speaker and author of “Future of food” mentions urban farms based upon hydroponics will be developed in megacities. By 2050, 80% of people will live in cities. Food and agriculture become more industrial than ever yet the small markets for seasonal & locally produced food gains popularity amongst elites & becomes more profitable.

The global hydroponics market is projected to reach USD 395.2 million by 2020, at a CAGR of 16% from 2015 to 2020.

    If there is some technology which is helping to reduce consumption of water then definitely one should go for it. After all water level is constantly going down . we should emphasize on sustainable development.

Women Who Consume Food Late in The Evening Likely to Suffer Heart Disease: Study

Data from the food diary completed by each woman was used to determine the relationship between heart health and the timing of when they ate

Women who consume a higher proportion of their daily calories late in the evening are more likely to be at risk of Heart Disease than women who do not, researchers have warned.

For the study, the research team assessed the cardiovascular health of 112 women using the American Heart Association’s Life’s Simple 7 measures at the beginning of the study and one year later.

Life’s Simple 7 represents the risk factors that people can improve through lifestyle changes to help achieve ideal cardiovascular health and include not smoking, being physically active, eating healthy foods and controlling body weight, along with measuring cholesterol, blood pressure and blood sugar levels.

A heart health score based on meeting the Life’s Simple 7 was computed.

“The preliminary results indicate that intentional eating that is mindful of the timing and proportion of calories in evening meals may represent a simple, modifiable behaviour that can help lower heart disease risk,” said study lead author Nour Makarem from Columbia University in the US.

During the study, participants of the study kept electronic food diaries by computer or cell phone to report what, how much and when they ate for one week at the beginning of the study and for one week 12 months later.

Data from the food diary completed by each woman was used to determine the relationship between heart health and the timing of when they ate.

Researchers found that, after 6 p.m. with every one per cent calories consumed heart health declined, especially for women.

These women were found more likely to have higher blood pressure, higher body mass index and poorer long-term control of blood sugar.

Similar findings occurred with every one per cent increase in calories consumed after 8 p.m.

“It is never too early to start thinking about your heart health whether you’re 20 or 30 or 40 or moving into the 60s and 70s. If you’re healthy now or if you have heart disease, you can always do more. That goes along with being heart smart and heart healthy,” said study researcher Kristin Newby, Professor at Duke University. (IANS)
