The importance of playgrounds in school spaces

India is a big country with a growing population as a concerning issue. There is an increase in construction activities such as, construction of flats, malls bungalows and so on. With land becoming scarce in these areas there is an increase in traffic, and problems of parking, pollution, and so on.

One of India’s biggest cities Ahmedabad, with a population of 52,52,197 has total number of schools at around 2323. (Gujarat Revenue Department) It has been reported that in the country, 52% schools do not have a playground. The same may be applied to Ahmedabad as well (India together). It is also interesting to see a British study (Find Articles) suggesting almost 60% to 80% students injured on school playgrounds. These same playgrounds generally have an important role in mental and physical growth of a child. When children are not involved in any co-curricular activities, they may also suffer from depression, and the proportion of such children according to an Australian study is 8.4%. (Medicine Net). One can note that playgrounds provide an avenue for a child’s mental and physical growth, which can help them bring out their various potentialities. Playgrounds are also useful during emergencies.

If a school does not have a playground, in an emergency situation, school authorities can make provisions for a party-plot, garden, or any such empty space close by so that children can be assembled during emergencies and their safety/security can be assured.

Approaches in Risk Reduction (The ALARP approach)

Activities at work or play can be hazardous, with it being in our nature to take precautions to protect ourselves from the unexpected accidents or disasters. There always exists a risk, but then a question can be asked- does one need to put efforts so as to reduce this risk, which may result in life, injuries or monetary losses to a minimal, if not zero? If yes, then what kind of effort and how much of it is needed?

In view of these, one can talk of approaches, or one can say frameworks which can be used in defining approaches towards risk reduction. Some of these well known approaches used are –

1. As Low As Reasonably Practicable (ALARP),
2. As Low As Reasonably Achievable (ALARA),
3. So Far As Is Reasonably Practicable (SFAIRP), and
4. There can be more.

Let us discuss ALARP in this post. ALARP, “As Low As Reasonably Practicable”, can be defined as an approach to reduce the risk to as low as possible using best available practices and standards. Here, “best Practice” can be referred to the best available technology in the best practicable environmental conditions. See Knol for a good explanation. Also see the figure below.

It is interesting to look at the HSE, UK for the definition of ALARP, and see how it came into existence. The case law of Edwards V. National Coal Board in 1949 became an act in 1974. The blog by Safety Health Environment Ltd, is useful to look at where Edward’s fatal accident, when a section of the road on which he was traveling subsided. The section of road concerned had no timber support although other sections were properly supported. Lord Asquith (the judge in National Coal Board) decided that it was not all of the roadways that needed shoring up; just the ones that required it. The Court of Appeal then decided that if the ‘consequences’ and the ‘degree of the risk’ are small and the ‘cost of the measures’ to reduce the risk is very expensive, it would be unreasonable to incur that cost. The UK legislation (Health and Safety at Work etc Act 1974) then defined ALARP where they ensured that all plants/equipments and systems at work are safe and without risks to health, or life.

In monetary terms, ALARP is subject to cost-benefit based risk reduction; where the benefit should outweigh the cost.

Therefore, it is more a best common practice of judgement to balance risk and benefit. ALARP is not used in the same way by other countries as in the UK, for it may be interpreted according to the local culture. There are similar other approaches like ALARA and SFAIRP which will need mentioning.

Earthquake Threat in the Indian Subcontinent- India Seismic Zone Map and its Field Implementation

It is well established that 60% of India’s population is estimated to be directly under earthquake threat. And, add some more to it, it will cover the whole South Asian subcontinent. One may like to reiterate that approximately 20% of the present world population lives in the subcontinent, and the region has a 10-15% decadal increase in population. The internet (wikipedia) link elaborately explains composition of these countries. See the image below for the increase in population of India over the last 60 years. The subsequent image shows comparative population increase in the subcontinent.

This increase in population coupled with concern of quality of structures being built leading to increased risk in these areas is thwarted with a parallel argument; whether things are actually that bad in these growing economies, such as South Asia?

Well, it is easier to immerse oneself in numbers or debate, and therefore, become lost. Or, else one can take note of the red spots in the zoning map with hope. Actually, the inspiration to this post is also the India’s earthquake zoning map until someone unknown re-filled the riskiest zone (Zone V) with red. Image below shows that Zone V is more dangerous than Zone II. Red draws most attention, and zoning can be, for ease of implementation, reflected by the fact that India’s seismic map has four zones now. Note Zone I doesn’t exist anymore in the map. This simplification was done to assist implementation in the vast plural context of India after the unfortunate 2001 Gujarat earthquake. This map is a result of the hard and perseverant intelligent work by the Bureau of Indian Standards along with senior experts such as Dr. Arya, and many other engineers who previously worked and have been working on this overwhelming issue of reducing earthquake vulnerability, or for that matter vulnerability to any natural disasters in the country.

Or, it can be argued that major factors - such as terrain, political, technological capacities, growth, to name some will continue to challenge the implementation of earthquake risk reduction activities in the subcontinent for the coming years. And in case of India, one can pick these red blocks and see clearly where urgent interventions are required - its North Eastern states, and states of Himachal Pradesh, Uttarakhand, and Bihar. Recent devastations in the subcontinent in Kashmir (2005) and Kutch (2001) are well known. These red spots are the riskiest spots, also known as ‘hot spots’. Perhaps, an independent but interconnected framework may help.

Amidst the so called tough ground realities, a stronger coordination is required to avert this ‘time bomb’. “We are sitting on a time bomb”, is what I recall during a meeting with a senior official at Shimla (Zone IV), a nice mellow hill town and state capital of Himanchal Pradesh; situated in a state that is tweaked red. It was 2004 then.
