Agriculture is the backbone of most of the developing countries in which a major part of their income comes from agriculture sector and more than half of their population depends on it for their livelihood.  The current global population is nearly 7.7 billion with 50% living in Asia. A large proportion of those livings in developing countries face daily food shortages as a result of environmental impacts or political instability, while in the developed world there is a food surplus. For developing countries, the drive is to develop drought and pest-resistant crops which also maximize yield. In developed countries, the food industry is driven by consumer demand which is currently for the fresher and healthier food products.

Specifically in agriculture, technical innovation is of importance with regard to addressing global challenges such s population growth, climate change and the limited availability of important plant nutrients such as phosphorus and potassium.

Nanotechnology has gained intense attention in the recent years due to its wide applications in several areas like medicine, medical drugs, catalysis, energy and materials. Those nanoparticles with small size to the large surface area (1-100nm) have several potential functions. These days, sustainable agriculture is needed. The development of nonchemical has appeared as promising agents for the plant growth, fertilizers and pesticides. In recent years, the use of Nano materials’ has been considered as the alternative solution to control pant pests including insects, fungi and weeds.

Despite these potential advantages, the agricultural sector is still comparably marginal and has not yet made it to the market to any larger extent in comparison with other sectors of nanotechnology application.

Nanotechnology helps agricultural sciences and reduce environmental pollution of pesticides and chemical fertilizers by using the nano particles and nano capsules with the ability control or delayed delivery, absorption and more effective and environmentally friendly and production of nano -crystals  to increase the efficiency of pesticides for application of pesticides with lower dose.

In the agricultural sector, nanotech research and development is likely to facilitate and frame the next stage of development of genetically modified crops, animal products inputs, chemical pesticides and precision farming techniques. The use of nanotechnology in agriculture has been mostly theoretical but it has begun and will continue to have a significant effect in the main areas of the food industry development of new functional materials, product development and design of methods and instrumentation for food safety and bio-security.

Since a long time ago, human has acknowledged the health benefits of foods. However, with the development of chemical drugs and pills, they have forgotten that foods they eat are directly linked to their health. Foods, in fact are the best medicines and therefore we should take into account carefully how we perceive and use them. Integrative medicine is one of the most practised ideas of wellness today.

Before we dive in, let’s start with the basics – what exactly IS Integrative medicine?

Integrative Nutrition Medicine is a system through the power of nutrition, primary food, active listening, high-mileage questions, goal setting, and other techniques unique to health coaching. While the average visit to the doctor only lasts eight minutes, the average health coaching session could be of about 50 minutes – an in-depth conversation between the health doctor and their clients.

Dr. Natalie cooke- Cover stoty- BiZnomics- An integrative medical doctor is a supportive mentor and wellness authority who helps others feel their best through individualized food and lifestyle changes that meet their unique needs and health goals. Often, they provide their services in private coaching practices with one-on-one sessions.

Integrative medicine isn’t about one diet or one way of living. Instead, focuses on bio-individuality – the idea that we are all different and have unique dietary, lifestyle, emotional, and physical needs. This means that integrative medicine does not believe in one-size-fits-all approach to health and wellness. Instead, integrative medical doctors work with clients to help them discover how to fuel their bodies and become healthiest, happiest version of themselves.

Dr. Natalie Cook is a medical doctor who currently practices and promotes integrative medicine through nutritive practice. She holds a Degree in Medicine and Surgery. She has previously worked at the Sri Lanka army hospital and Maharagama cancer hospital and completed her MBBS and Double Master’s Degree in Medical Administration. She also studied and specialized in drugless therapies.

BiZnomics had the pleasure of speaking to Dr. Natalie Cook in her journey as the doctor who introduced integrative medicine to Sri Lanka.

You are a professionally qualified doctor. What made you decide to move to integrative medicine?

I have always looked at the body as a whole. I don’t believe in compartmentalizing it into systems or organs and treating it separately. There is a truth to ancient medicine and I wanted to bring it back to the present. We have got so used to a quick fix that chemicals have become our go to for everything. I want to remind people that they shouldn’t be polluting the human body to such an extent.

 

Where did you receive your training?

My MBBS is from Tianjin Medical University. My specialization in Nutritive Medicine is associated with Mayo Clinic USA. I received all my certifications from CAM Sri Lanka.

Why Hydroponics? 0 401

BiZnomics- Why hydeoponics-1

Hydroponics is a system of soilless cultivation using water-based nutrients.

Hydroponics, by definition, is a method of growing plants in a water-based, nutrient-rich solution. Hydroponics does not use soil, instead, the root system is supported using an inert medium such as perlite, rock -wool, clay pellets, peat moss or vermiculite.

The hydroponic system offers farmers the ability to grow crops in areas where traditionally it would simply not be possible (like mountain lettuce at sea level in Sri Lanka). Growing hydroponically (as with vertical farming, aquaponics, aeroponics etc) also saves a lot of land space.

Many growers believe that growing in a soilless medium requires about the same effort as growing in soil. Not as fast as full Hydro-Growing in a soilless medium will get faster growth rates in soil, but cannabis plants will not grow as fast as a hydroponic medium that is able to get more oxygen to the roots.

Well managed hydroponic set-ups are also highly energy-efficient and their existence places less strain on the environment than many traditional ‘monoculture’ farming systems. Water is recycled throughout the hydroponic system, greatly reducing the overall volumes required. As a general benchmark, it is considered that the hydroponic system use as little as 10% of the water required for soil-based agriculture.
