Wonder Of The Greenhouse Effect

In arid cold desert of Ladakh, the changing seasons signifies a completely different lifestyle for its people.  Summers are short when few vegetables can be grown in the plain areas and when the cattle herds can be taken up to the mountains to graze in the green, luxuriant pastures.  All this would change after October when the temperatures start plummeting; when snow starts to cover the mountains and icy wind begin to blow.
The road links primarily National Highways from Manali in Himachal Pradesh and from Srinagar begin to look deserted and slowly get covered by snowfall, so thick and continuous that it takes a long time to melt and clear once the winter ends.  To the rest of the world, Ladakh remains cut off, inaccessible for six months.  The whole region gets covered by a white blanket of snow.  But how do the people manage, in this bone-chilling, mind-numbing winter?  The whole of Ladakh goes into a deep recess with all of life being sustained on resources gathered and stored in the summer.
Around 90 percent of Ladakhi people are dependent on agriculture for their livelihood.  In the rest of the country, we hear of two seasons of cultivation, the ‘rabi’ and ‘kharif’. The range of crops that can be grown in the plains is vast, their sowing and harvesting being done according to seasons. Here in Ladakh the farmers have to cultivate land in a very compressed time frame with a limited range of cultivable crops. 
In the long winters, where does the food, specially the vegetables come from, considering the short growing period and limited range of crops?  It is required for keeping up the nutritional needs of the people. In Ladakh, one is dependent on what has grown before the snow begins to fall.    Airlifting vegetables from outside is simply too expensive.
I know these processes only too well, coming as I do from an agricultural background. I vividly remember when as a child, my grandparents would take me to the fields and dig the ground (sadong) deep, down to 5-6 feet.  Curious, I would scamper around and ask why the soil was dug so deep.  Nodding wisely, my grand mother then told me a fact, which is a truism for all time, for all people in Ladakh. “We have a long winter ahead, so we have to store vegetables like potato, carrot, radish and turnips for survival”.
Grandmother’s words have remained with me and today I can see the wisdom in it, signifying a way of life, a pattern of consumption for the entire region, a pattern that ensures their very survival.  If you slip up here, nature is unlikely to give you a second chance.  A totally different scenario from the plains where you just walk down or cycle down or take a bus at the most to the nearest mandi. If vegetables are not available on one day for any reason, you are bound to get them the next day.  In Ladakh you will have to wait for the season to change for that to happen! 
Still everything was not perfect.  Left in this kind of storage, deep underground, there were problems of ventilation.  The moisture in the ground, lack of air would make the vegetables rot gradually.  Of course, they would not rot all together; yet it was impossible to ‘isolate’ the ones which were rotting fast and the rest, so in the end, it the entire mass would be affected.  Some could be salvaged and consumed fast, others thrown away. Every winter, it would be an exercise in deft management of underground supplies; the price to pay was heavy however.  The lack of fresh food would invariably affect the health of the people.  Malnutrition, heart diseases, indigestion, acidity and body fatigue were common.
Age-old practices of cultivation, cooking, consumption and also storage have been followed in Ladakh, evolved by our ancestors, who have observed nature’s patterns and developed practices in sync with it. . However, as I grew up, I realised that we need to move beyond this traditional wisdom, to evolve  ‘good practices’ based on modern technologies to improve the quality of life in the region.
I have been amazed and delighted both to find Greenhouses coming up on Ladakh’s desolate and icy landscape over the last few years. The region is blessed with plentiful sunshine in the winter months.  The Jammu and Kashmir state government has taken cue from this and introduced an initiative to build these structures. Now farmers in Ladakh have the option of. Growing vegetables throughout the year, something unbelievable in grandmother’s days! I was glad to be witnessing this change, in era, in practices, in the way of life that us Ladakhis have known over the generations.
It is actually a concerted effort. Government departments like Horticulture, Sher-e-Kashmir University of Agricultural Sciences and Technology (SKUAST), Agriculture and Defence Research & Development Organisation (DRDO) all are involved in this initiative. Non governmental organisation like Ladakh Environmental and Health Organisation (LEHO) also have played an important role in creating awareness amongst the farming community about new technologies.  providing hybrid seeds. And offering support to build these structures including providing poly film on subsidised basis
The ‘Greenhouse effect’ if it can be called that in Ladakh has a salutary effect, not only on the food production, sustainability and diversification of crops but an additional income to its vast majority, still dependent on farming in this high desert mountainous region.  The results are stupendous.  Farmers are growing vegetables which for Ladakh are exotic; capsicum, cucumber, brinjal, cauliflower onion, carrot, spinach tomato, chilli broccoli and knol khol.  They are also growing seeds, gradually getting into multiple cropping. Unheard of plant varieties like rose garlic, sweet potato, asparagus are now growing beautifully in the winter season and being ready for planting of their cutting again in the early spring out in the open.  This is really Ladakh’s version of ‘rabi’ and ‘kharif’!
For my grandmother’s generation, it is nothing short of a miracle. Biting frost outside and all these wonderful vegetables happily growing, cocooned in their hothouses, receiving the goodness of sunshine within and protected from the cold without. This is not a miracle, but a technological marvel, a sign of the changing times.  To use the scientific and technological advances for the good of the people, particularly in harsh terrains like Ladakh is what I believe to be wisdom, equal to but different from those passed down over the generations.

Nagarjunasagar Wildlife Sanctuary
      Evolved out of different needs, the town of Srisailam is divided into three zones. Srisailam or the original pilgrim town centers round the age-old temples dedicated to Lord Mallikarjuna and Goddess Bhramaramba, incarnations of Shiva and Parvati. A fairly stocked marketplace and several lodges for pilgrims lie alongside the temple quadrangle.About eight kilometers from the temple town is Sunnipenta, another ridge top where most offices and a few eating houses are located. Also located here is the office of the Project Tiger and the Field Director. The dam site on the river Krishna-the Srisailam Hydel Projects-makes up the third zone.

     

Nestling in the Nallamalai Hill ranges, an offshoot of the Eastern Ghats, with cliffs, gorges, ridges and plateaus, endowed with a variety of flora and fauna, the NSTR protects a large portion of the once flourishing ecological system that existed here. Without having the benefit of being an erstwhile royal game preserve, the forest in this area was always open to human visitation. Pilgrims from all over southern India carved out routes through the forest to reach Srisailam. It was in 1973 that the area was declared a sanctuary and incorporated under Project Tiger a decade later.

     

A little over 6 sq km in area, the Rollapadu grasslands near Srisailam are dotted with dry, thorny bushes and is home of about a hundred blackbucks. From a distance, one can observe families of blackbucks out on their breakfast trail, a couple of bustards gazing at the horizon while taking a tentive foot forward. At present, day visits to Rollapadu Sanctuary is permitted.
     

     

Places Nearby Nagarjunasagar Wildlife Sanctuary:
      Mannanur is a pre-existing tribal hamlet with a comfortably furnished camp bungalow. Next to the bungalow are a crocodile pond and an environment education center. From Mannanur, one can explore the western corner of the tiger reserve. The forest area here is thickly set with miscellaneous timber species with local names like Nallamadi (Terminalia tomentosa), Chirumanu (Anogeissus latifolia), etc., as well as stretches of teak forest. One can also spot spotted deers, sambars, and nilgais here.Nagarjunasagar is the place where excavations have unearthed many historical monuments belonging to 1st and 2nd century AD. The place is also home to a large dam built on the river Krishna.

Troposphere ozone layer acts as a shield against all ultraviolet radiation approaching the planet Earth through absorption. It was noticed in mid 80s that ozone layer has thinned on the poles of the planet due to release of man-made substances commonly known as Ozone Depleting Substances, (ODS) into its atmosphere. The consequences of this change are adverse as the harmful radiations reach to the surface of the earth, strongly influencing the crops yield and vegetation. These radiations are also a major cause of skin cancer that has long exposure to Ultra Violet (UV) radiation.

      
 About 90 per cent of the Earth’s protective ozone layer resides in the stratosphere between 15km and

50km altitude. Molecular oxygen is broken down in the stratosphere by solar radiation to yield atomic oxygen, which then combines with molecular oxygen to produce ozone. Ozone is destroyed naturally through a series of catalytic cycles involving oxygen, nitrogen, hydrogen and to a lesser extent chlorine and bromine species. The abundance of stratospheric ozone is therefore chemically controlled by the stratospheric abundances of compounds containing hydrogen, nitrogen, chlorine and bromine. Increases in the abundances of methane and nitrous oxide (sources of hydrogen and nitrogen oxides respectively) thus affect the abundance and distribution of stratospheric ozone. Stratospheric ozone is also affected by the abundance of carbon dioxide (CO2), because the rates of the chemical reactions that control the abundance of ozone are temperature-dependent, and the abundance of CO2 plays a key role in determining the temperature structure of the stratosphere. While methane is a more potent greenhouse gas than CO2, there is over 200 times more CO@ in the atmosphere. Hence the amount of warming methane contributes is 28% of the warming caused by CO2.

      

A United Nations report has identified the worlds rapidly growing herds of cattle as the greatest threat to the climate, forests and wildlife. Livestock are responsible for 18% of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together. Burning fuel to produce fertilizer to grow feed to produce and to transport it – and clearing vegetation for grazing – produces 9% of all emissions of CO2, the most common greenhouse gas. And their wind and manure emit more than one third of emissions of another, methane, which warms the world 20 times faster than CO2.

      

Livestock belch out or release methane gas as they digest their food. And a methane molecule released into the atmosphere, has a 25 times greater capacity for trapping heat than a carbon dioxide molecule. Rice, meat, dairy products and fish are associated with high methane emissions while wheat, vegetables and fruits contribute to an oxide of nitrogen – another greenhouse gas that has an even greater heat trapping capacity than methane. Bananas had the least global warming potential, according to the research analysis inasmuch as much of the emissions associated with bananas emerge from their transportation from plantations to retail outlets.

      

In early 1990s, the Indian scientists were caught by surprise when the US researchers had suggested that India’s paddy fields were producing a large amount of methane unmindful of the fact that the livestock industry had a much bigger impact on the environment. This prompted an indigenous research in the subject that showed that the US claims were far exaggerated. The research also led to the assessment of the greenhouse gas emissions during each stage, of the lifecycle of various food items from the farm to the dining table viz. production, processing and cooking, so to say, to generate a comparative chart.        The research designed to generate raw data about the global warming potential of Indian food items has determined the Global Warming Potential in gram carbon dioxide per kg thus: Apple (357), Banana (98), Basmati rice (859), Chapati (250), Dosa (729), Fish (756), Idli (682), Parantha (261), Potato (132), Poultry meat (801), Milk (766), Mutton (9149), Rice (712). ( Stop Smoking for the sake of life )

      

The data thrown up as above clearly shows that a kilogram of mutton has a global warming potential 12 times higher than a kilogram of fish. The global warming potential of poultry meat – chicken or duck – is only slightly higher than that of fish. It also makes it abundantly clear that vegetarians are far more environment-friendly than the non- vegetarians. For the sake of the planet earth and for their own sake, the latter can do their bit by eating a little less meat – or better still, shift over to “mock meats” or vegetarian meats, now available in a large number of Washington area restaurants, where the wizardry and skill of counterfeiting meat has become a sophisticated art.
