Compost no solution to fertiliser issue
Most writers have referred to compost as organic fertiliser, which is technically incorrect. Incorporation of compost into agricultural lands is not new. It is an age-old practice. The nutrient content of compost is about 2%, which is negligible compared to what inorganic fertilisers yield, e. g. to get the same amount of nitrogen obtained from 100 kg of urea one needs 2300 kg of compost. Therefore, it is not possible to compare compost manure with inorganic fertiliser.
Compost at best is a soil conditioner, which improves the physical properties of a soil and is complementary when used in conjunction with inorganic fertiliser. Benefits of the use of compost are manifold. Foremost amongst them are: Improves water holding capacity;
Improves cation exchange capacity meaning availability of nutrients to plants; Improves aeration; Improves the tilth of the soil. Enhances the soil microflora important in healthy plant growth.
As a lot has been said by others, I will not attempt to elaborate on a comparative analysis.
It is important to bear in mind that compost has no set standard. It can vary from one source to another. Somebody has advocated the use of poultry manure in large doses. It is very acidic and rich in phosphates. It can also contain undigested antibiotics, used widely in the industry. These things can get washed away and enter water bodies, which eventually enter the human body, Danger!
It must also be said that some writers adopted a hunt with the hound and run with the hare kind of attitude when dealing with the subject. They tried to soften the deadly blow by saying that it should have been a phased-out transition going up to 20 years for a complete change. How come? Even in 100 years, inorganic fertilisers can never be replaced with compost. It will be a futile attempt. As most of us know, if the ban on importation of inorganic fertilisers and agrochemicals continue, the first victim would be the tea industry, followed by all short-term crops, like vegetables, including potato, rice and so many others. We easily could once again be another first in the world. Records would tumble for the asking.
On a different note, a big noise was made recently that the sugar industry is switching over to compost as fertiliser! The writer spent about 30 years in the sugar industry, in different capacities as research manager, plantation manager, general manager, advisor and, until recently, as consultant. The present plight of the industry is quite pitiable. We recorded sugar recoveries of 8.5-9% from certain plantations, which now yield bearly 6%. It means a drop of 2.5-3 tons of sugar from every 100 tons crushed. Considering that they crush about 250,000 tons, the loss is about 7500 tons of sugar and Rs. 750 million. Sizable indeed. The recovery in certain factories today is a little over 5%.
Sugar is made in the field by the cane, and the factory only extracts it. Sugar does not accumulate automatically in the cane. It has to be managed, and the fertiliser plays an important role in it. The type of fertiliser applied and its timing are vital. Compost, besides other constraints, cannot do this. I will not dwell further on sugar. It is a different kettle of fish.
Where are we heading?

A harsh reflection of Sri Lanka’s early-warning gap
Cyclone Ditwah:
Cyclone Ditwah, which swept across Sri Lanka at the end of November, caused massive damage to the country, the extent of which need not be mentioned here, as all are aware of it by now. Heated arguments went on among many parties with regard to how this destruction could have been mitigated and who should take responsibility. Although there may have been shortcomings in several aspects of how we responded to Ditwah, this article highlights a critical area that urgently requires attention if we are to protect ourselves from similar hazards in the future.
As is common in many situations, it has once again showcased a concerning weakness in the country’s disaster-management cycle, the gap between issuing early warnings and the expected public response. The Meteorological Department, the Irrigation Department, the National Building Research Organization, and other authorities issued continuous warnings to evacuate well in advance of imminent threats of flooding, landslides, and water hazards. However, the level of preparedness and community reaction fell short, leading to far greater personal property damage, including loss of a few hundred lives.
Sri Lanka is not unfamiliar with natural disasters. One of the most devastating disasters in our history could be considered the 2004 Tsunami event, which resulted in over 35,000 deaths and over $1 billion in property damage in the coastal belt. After the event, the concepts of disaster management were introduced to the country, which we have been adhering to since then. Again in 2016, the country faced massive river flooding, especially in western and southern regions, and until recently experienced repeated floods and landslides due to rains caused by atmospheric disturbances, though less in scale. Each of these events paved the way for relevant authorities to discuss and take appropriate measures on institutional readiness, infrastructure resilience, and public awareness. Yet, Cyclone Ditwah has demonstrated that despite improvements in forecasting and communication, well supported by technological advancements, the translation of warnings into action remains critically weak.
The success of early-warning systems depends on how quickly and effectively the public and relevant institutions respond. In the case of Ditwah, the Department of Meteorology issued warnings several days beforehand, supported by regional cyclone forecasting of neighbouring countries. Other organisations previously mentioned circulated advisories with regard to expected flood risk and possible landslide threats on television, radio, and social media, with continuous updates. All the flood warnings were more than accurate, as low-lying areas were affected by floods with anticipated heights and times. Landslide risks, too, were well-informed for many areas on a larger spatial scale, presumably due to the practical difficulties of identifying such areas on a minor scale, given that micro-topography in hill country is susceptible to localised failures. Hence, the technical side of the early-warning system worked as it should have. However, it is pathetic that the response from the public did not align with the risk communicated in most areas.
In many affected areas, people may have underestimated the severity of the hazard based on their past experiences. In a country where weather hazards are common, some may have treated the warnings as routine messages they hear day by day. As all the warnings do not end up in severe outcomes, some may have disregarded them as futile. In the meantime, there can be yet another segment of the population that did not have adequate knowledge and guidance on what specific actions to take after receiving a warning. This could especially happen if the responsible authorities lack necessary preparedness plans. Whatever the case may be, lapses in response to early warnings magnified the cyclone’s impact.
Enforcing preventive actions by authorities has certain limitations. In some areas, even the police struggled to move people from vulnerable areas owing to community resistance. This could be partly due to a lack of temporary accommodation prepared in advance. In some cases, communities were reluctant to relocate due to concerns over safety, privacy, and the status quo. However, it should be noted that people living in low-lying areas of the Kelani River and Attanagalu Oya had ample time to evacuate with their valuable belongings.
Hazard warnings are technical outputs of various models. For them to be effective, the public must understand them, trust them, and take appropriate action as instructed. This requires continuous community engagement, education, and preparedness training. Sri Lanka must therefore take more actions on community-level disaster preparedness programs. A culture of preparedness is the need of the day, and schools, religious institutions, and community-based organisations can play an important role in making it a reality. Risk communication must be further simplified so that people can easily understand what they should do at different alert levels.
Cyclone Ditwah has left, giving us a strong message. Even an accurate weather forecast and associated hazard warnings cannot save lives or property unless the public responds appropriately. As it is beyond doubt that climate change intensifies the frequency and severity of extreme weather events, people in Sri Lanka have to consider preparedness as a routine part of life and respond to warnings promptly to mitigate damage from future disasters.

Feeling sad and blue?
Here is what you can do!
Comedy and the ability to have a good laugh are what keep us sane. The good news to announce is that there are many British and American comedy shows posted up and available on the internet.
They will bring a few hours of welcome relief from our present doldrums.
Firstly, and in a class of its own, are the many Benny Hill shows. Benny is a British comedian who comes from a circus family, and was brought up in an atmosphere of circus clowning. Each show is carefully polished and rehearsed to get the comedy across and understood successfully. These clips have the most beautiful stage props and settings with suitable, amusing costumes. This is really good comedy for the mature, older viewer.
Benny Hill has produced shows that are “Master-Class” in quality adult entertainment. All his shows are good.
Then comes the “Not the Nine o’clock news” with Rowan Atkinson and his comedy team producing good entertainment suitable for all.
And then comes the “Two Ronnies” – Ronnie Barker and Ronnie Corbett, with their dry sense of humour and wit. Search and you will find other uplifting shows such as Dave Allen, with his monologues and humour.
All these shows have been broadcast in Britain over the last 50 years and are well worth viewing on the Internet.
Similarly, in The USA of America. There are some really great entertainment shows. And never forget Fats Waller in the film “Stormy Weather,” where he was the pianist in the unforgettable, epic, comedy song “Ain’t Misbehavin”. And then there is “Bewitched” with young and glamorous Samantha Stevens and her mother, Endora who can perform magic. It is amazing entertainment! This show, although from the 1970s was a milestone in US light entertainment, along with many more.
And do not overlook Charlie Chaplin and Laurel and Hardy, and all the Disney films. Donald Duck gives us a great wealth of simple comedy.
The US offers you a mountain of comedy and good humour on Youtube. All these shows await you, just by accessing the Internet! The internet channel, ‘You tube’ itself, comes from America! The Americans reach out to you with good, happy things right into your own living room!
Those few people with the ability to understand English have the key to a great- great storehouse of uplifting humour and entertainment. They are rich indeed!

There is much to learn
After the recent disaster, a great deal of information has been circulating on WhatsApp and YouTube regarding our reservoirs, highways, etc.
In many of these discussions, people have analysed what went wrong and how the damage could have been prevented. My question is this: why do all these knowledgeable voices emerge only after disaster strikes? One simple reason may be that our self-proclaimed, all-knowing governing messiahs refuse to listen to anyone outside their circles. It is never too late to learn, but has any government decision-maker read or listened to these suggestions?
When the whole world is offering help to overcome this tragedy, has the government even considered seeking modern forecasting equipment and the essential resources currently not available to our armed forces, police, and disaster-management centres?
