The greatness of water

“Venerated from a time before antiquity as life-giver, water has been held in the highest esteem in all cultures and eras. Water-related mythologies show as much the divine character associated with it, as its qualities that lie beyond the material. In our time, the intangible cultural heritage (ICH) and traditional knowledge that surround water still give us an entryway to a fuller understanding of the great life-giver.”

This is the introduction to my paper which has been published as a chapter in the book titled ‘Water: Interconnectivity between the Intangible Cultural Heritage and Science’, which is a joint publication by two centres, the International Information and Networking Centre for Intangible Cultural Heritage in the Asia-Pacific Region (ICHCAP) and the International Centre for Water Security and Sustainable Management (i-WSSM), both being UNESCO centres in the Asia-Pacific region and based in South Korea. The book is also part of the ‘Living Heritage Series’ published by ICHCAP.

My association with the ICHCAP centre goes back several years. As per the centre’s description of the book, it is meant to “promote the convergence of science and intangible cultural heritage (ICH) fields; to spread the value of the intangible cultural heritage of water. Nine stories on water management and water and culture were gathered in one place. It contains stories about water-related ICH elements, such as water management as the transmission of traditional knowledge and agriculture as water-related culture. Through this book, readers will be able to explore the value of water, which is an essential factor for humankind, from a cultural perspective.”

More from ‘With Okeanos and Ganga, the greatness of water’:

“But Ganga herself—for the great majority of the rivers in the Indian subcontinent are indeed feminine, a clear sign of the universal acknowledgment to be found among the very oldest cultures of the world that life-giving and life-sustaining waters are embodiments of the feminine force—has a mythic history.”

“Dispatched to the realms of man because of her transgressions in the heavenly realm, her descent to Earth would have been ruinous, an apocalypse, had she not been caught in the matted locks of the great god Shiva, the original yogi, who in so doing prevented all on Earth from being washed away by the force and volume of her waters. When set free, Ganga followed the course she currently occupies; in the mythic account it is said thereafter she descended further into the realm below that occupied by humans, and in this way Ganga watered all three worlds.”

“These accounts are very rich in allegorical symbolism, and it is the codes that have been included in the mythic retellings of the tale that signal the metaphysical consideration of the water element. These are the codes that—like so many concerning the stories of creation that abound in old cultures and within the unimaginably ancient seam of oral accounts told and retold by indigenous peoples—point to the true characteristics of what we have become used to calling the “elements,” such as water.”

“Similarly, in the ancient Greek cosmogony the Okeanos River was a great freshwater stream that encircled the flat disk of the Earth. It was considered in this cosmogony to be the source of all of the Earth’s fresh water, from the rivers and springs that drew their waters from it through subterranean aquifers, to the clouds that dipped below the horizon to collect their moisture from its stream. Okeanos also marked the outer boundary of the flat earth that it surrounded with a nine-fold stream. The Sun, Moon, and stars all rose from and set into its waters. At night the Sun god would sail around its northern reach in a golden boat to reach his rising place in the east from his setting point in the west. In a cosmological sense, the river symbolized the eternal flow of time.”

India’s material burden, gigantic and unseen

Mumbai as seen from an aircraft coming in to land. Neither city households nor wards care about the material throughput they cause and live with every day, week, month. Electricity and water, packaging and food, all contribute to the household footprint.

Should a trend continue as it has done for the last ten years, then in February or March of 2021 India’s annual extraction of material will cross 7.5 billion tons. It was in 2011, only eight years ago, that the country’s material extraction had crossed six billion tons. This stupendous mass comprises what are called non-metallic minerals, most of it limestone, structural clays, and the several kinds of mixtures of sand, gravel and crushed rock that are used for construction, which in 2017 amounted to an estimated 3.2 billion tons.

[This article was published in The New Indian Express.]

There was biomass, by which is meant harvested crops – foodgrain, horticultural crops, pulses, sugarcane and plantation crops – and crop residues, both straw and leaves, which was an estimated 2.8 billion tons (sugarcane accounting for nearly 370 million tons), coal of 732 million tons and wood of an estimated 242 million tons (of which about 210 million tons were used as fuel). Collated from data provided by national agencies, the International Resource Panel of UN Environment maintains the material use profiles of nearly every country.

Apportioned by household, at the beginning of 2020 this vast material budget can be atomised to about 26 tons for each, in much the same way as per capita income is calculated, as a notional distribution, for each individual of India. Yet material allocation is a measure that, for all its tangible bulk, is treated as nearly invisible. Money and income, wages and savings, credit and assets are calculated and assessed to the third decimal by the financial services industry. But there is no corresponding industry to measure, assess and pronounce upon the solvency of the material intake of a household, whether in quintals or in kilograms, whether as fluid diesel or as grain or as burnt brick.

When it comes to the physical basis for the household’s shelter, its roster of daily consumption, the durable goods purchased and disposed of, its tribe of electronic gadgets, there is no literacy effort to be found run by any industry, or by government, or even by centres of higher education. The Indian household – whether amongst the estimated 96 million in urban centres or the 183 million in villages – is transiting from circumspection born of scarcity to profligacy in material accumulation.

The forms and vegetal densities of a typical ruralscape of coastal Tamil Nadu, this being near Pondicherry. Unlike the overground forms of a town, here there is no disharmony. Dwellings, orchards, crop fields, bunds, tracks, ponds all blend in material balance.

That the consequences of such a trend cannot be contained or managed in a meaningful way was already being signalled to us a generation ago, when our mega-metropolises (cities and adjacent urban agglomerations with a combined population of 10 million and more) found no alternative to the small hills of refuse and compacted rubbish that towered over some unfortunate outlying ward. Those hills have only become larger at a faster pace, and they are joined – as a new category of topological landform – by the waste and rubbish pits (‘landfills’ in the American vernacular) that the great majority of our class 1 cities (population of 100,000 and more) turn to as their means to deal with the accumulation of unwanted material.

How did the material burden of our settlements grow so quickly? Part of the reason must be ascribed to the collective race away from poverty, both monetary and of basic goods. It is rare to find today a discussion about whether a poverty line is reasonable or not, although a generation ago it was an important subject just as it was in the previous generation. The race has been set as one by the intentions and terminologies of a kind of economics based almost wholly on the concept of development. Thus one of the standard references for many years, the Cambridge Economic History of India, advised that “the declared goals of development policy were to bring about a rapid increase in living standards, provide full employment at an adequate wage, and reduce inequalities arising from the uneven distribution of income and wealth.”

Yet the development policies of the socialists, of those who designed the ‘command economy’, of the licence raj mandarins, of the globalisers, of the commodities capitalists, of the services barons, of the infotech-biotech persuasions, not one of these policy pathways has advised where sufficiency lies, and what to do after we have consumed our way out of poverty and into maintenance. None of these can, because ‘growth’ and market control is the engine that motivates their methods. Sufficiency – or consumption stability – also has the accompanying corollaries of societies making purchases last (by repairing and reusing them) and not purchasing at all.

The weekly intelligencer

Indices, prices, data series, readings and jottings of note over the last week, fortnight and month, compiled for the week beginning 6 August 2017.

Quick Estimates of Index of Industrial Production (IIP) with base 2011-12 for the month of May 2017, released by the Ministry of Statistics and Programme Implementation, Central Statistics Office. The General Index for the month of May 2017 stands at 124.3, which is 1.7% higher as compared to the level in the month of May 2016.

India Meteorological Department, Hydromet Division. Until 2 August 2017, 67% of the districts have recorded cumulative rainfall of normal, excess or large excess and 33% of the districts have recorded cumulative rainfall of deficient or large deficient. This compares with 69% and 31% respectively at the same time last year.

Ministry Of Commerce and Industry, Office Of The Economic Adviser. The official Wholesale Price Index for All Commodities (Base: 2011-12=100) for the month of June 2017 declined by 0.1% to 112.7 (provisional) from 112.8 (provisional) for the previous month.

Ministry of Water Resources, Central Water Commission. As on 3 August 2017 the total live storage capacity of the 91 major reservoirs is 157.799 billion cubic metres (BCM) which is about 62% of the total estimated live storage capacity of 253.388 BCM. As per reservoir storage bulletin dated 03 August 2017, live storage available in these reservoirs is 67.683 BCM, which is 43% of total water storage capacity of these reservoirs. Last year the live storage in these reservoirs for the corresponding period was 65.109 BCM and the average of last 10 years was 69.510 BCM.

Reserve Bank Of India Bulletin, Weekly Statistical Supplement. 4 August 2017. Aggregate deposits Rs 106,254 billion. Bank credit Rs 76.888 billion. Money stock: Rs 14,689 billion currency with the public, Rs 101,600 billion time deposits with banks.

Ministry of Agriculture. The total sown area as on 4 August 2017 stands at 878.23 lakh hectare as compared to 855.85 lakh hectare at this time last year. Rice has been sown/transplanted in 280.03 lakh hectare, pulses in 121.28 lakh hectare, coarse cereals in 156.95 lakh hectare, oilseeds in 148.88 lakh hectare, sugarcane in 49.71 lakh hectare and cotton in 114.34 lakh hectare.

The drying of the Deccan

This panel of 12 images shows the change that takes place in a region of the Deccan. Each image shows what is called a Normalised Difference Vegetation Index (NDVI) for the region. This is a rolling eight-day series computed daily using imagery from the Terra/MODIS system and viewed using the NASA Worldview website.

The colours (green and brown shades, whitish shades) show us the vegetation health with deep green being better than light green, dark brown being better than light brown. The index is also used to signal where areas are beginning to experience arid and water-scarce conditions.

The region is the west-central Deccan – the Karnataka Plateau – corresponds to the Vijayapur (Bijapur) district of north Karnataka with parts of Bagalkot district and is part of the central Indian semi-arid bioclimatic zone.

The pictures in the panel show the vegetation extent and health (NDVI) calculated on that day for an eight-day period. Each picture is a fortnight apart, and this series starts on 4 November 2016 (bottom right) and ends on 7 April 2017 (top left). The retreat of the green is seen clearly from one fortnight to the next.

Of interest in this region is the Almatti dam and reservoir, in the Krishna river basin, which is visible in the lower centre of each picture. On 13 April there was no water in Almatti, which has a full capacity of 3.105 billion cubic metres (bcm). For the week ending 30 March it had 0.015 bcm of water, the week ending 6 April 0.001 bcm.

For the week ending 3 November 2016, which is when the panel of pictures begins, Almatti had 2.588 bcm of water. The reservoir water runs a hydroelectric power plant, of 240 MW, and which needs flowing water to turn the turbines.

When the reservoir is full, the hydel plant produces about 175 million units of electricity. But on 13 March the Central Electricity Authority’s daily report showed that Almatti could produce only 3.02 million units. On 10 April, this had plunged to 0.04 million units, but the hydel plant had produced no power since 1 April.

Dimensions of drought

We lack not at all for experience with drought, yet have not grown used to treating water with the greatest of care. Drought does not strike in the manner a hailstorm does, yet our administrations seem unable to read the signals. Citizens and panchayats alike can contribute to our managing droughts better, provided all are willing to change both perception and behaviour.

It is because drought is such a forbidding condition for any state to fall into that it becomes at once threatening and emotive. Its every symptom becomes a new trial for a drought-afflicted population and simultaneously a likely indictment of the administration, whether local or regional. Food and crop, water and health, wages and relief: this is the short list for which action is demanded by a population concerned for those in the drought-affected districts and blocks.

The administration is bound to answer, as it is likewise bound to plan, prepare, anticipate and act. But where the interrogation of a government for its tardiness in providing immediate relief comes quickly, a consideration of the many factors that contribute to the set of conditions we call drought is done rarely, and scarcely at all when there is no drought. It is the gap between these two activities that has characterised most public criticism of the role of administration today when there is drought.

For farmers and district or block-level administrators alike, drought is a normal and recurrent feature of climate in the dryland regions of India. It occurs in nearly all climatic zones – our long recording history of droughts and floods in particular show that whereas in eastern India (West Bengal, Odisha and Bihar) a drought occurs once in every five years, in Gujarat, East Rajasthan and western Uttar Pradesh the frequency is once in three years. Although the characteristics of what we call drought varies significantly from one meteorological sub-division to another, and indeed from one agro-ecological zone to another, the drought condition arises from a deficiency in precipitation that persists long enough to produce a serious hydrological imbalance.

Drought is a complex phenomenon. There is first a need to distinguish between meteorological and agricultural droughts. A meteorological drought is a period of prolonged dry weather conditions due to below normal rainfall. An agricultural drought refers to the impact caused by precipitation shortages, temperature anomalies that lead to increased evapotranspiration by crops and vegetation, and consequently to a shortage of the water content in the soil, all being factors that adversely affect crop production and soil moisture. The National Commission on Agriculture has defined an agricultural drought differently for the kharif (monsoon cropping season, July to October) and rabi (winter cropping season, October to March).

What the country has witnessed during March and April is an agricultural drought, brought about by the high temperatures which raised mean and maximum temperatures into the heat-wave band. This we have witnessed in Odisha, Telengana, Vidarbha, Marathwada, north interior Karnataka, Rayalaseema, coastal Andhra Pradesh, Tamil Nadu, eastern Madhya Pradesh and Chhattisgarh, Jharkhand and West Bengal.

Food, climate, culture, crops and government

The weekly standardised precipitation index of the India Meteorological Department (IMD) which is a running four-week average. This series shows the advancing dryness of districts in south India.

In November 2015, the Departmentally Related Standing Committee on Agriculture of the Lok Sabha, Parliament of India, invited suggestions and submissions on the subject “Comprehensive Agriculture Research based on Geographical Condition and Impact of Climatic Changes to ensure Food Security in the Country”.

The Committee called for inputs on issues such as the need to evolve new varieties of crops which can withstand climatic fluctuation; requirement to evolve improved methods of irrigation; the need to popularise consumption of crops/fruits which can provide better nutrition; the need to develop indigenous varieties of cattle that can withstand extreme climatic stress; the need to develop a system for precision horticulture and protected cultivation; diversification of species of fish to enhance production from the fisheries sector; the need to strengthen the agriculture extension system; and means to focus on agriculture education.

I prepared a submission as my outline response, titled “Aspects of cultivation, provision of food, and use of land in Bharat today and a generation hence”. The outline I provided includes several issues of current urgency and connects them to scenarios that are very likely to emerge within a generation. My intention is to signal the kinds of pathways to preparation that government (central and state) may consider. It is also meant to flag important cultural and social considerations that lie before us, and to emphasise that economic and quantitative measurements alone are not equipped to provide us holistic guidance.

The outline comprises three sections.
(A) The economic framework of the agriculture and food sector and its imperatives.
(B) The social, ecological, and resource nature of crop cultivation, considering factors that influence it.
(C) Methods, pathways and alternatives possible to adopt with a view to being inter-generationally responsible.

In view of the current climatic conditions – heat waves in the central and eastern regions of the country, stored water in our major reservoirs which are at or near ten-year lows – I reproduce here the section on the economic framework of the agriculture and food sector and its imperatives. The full submission can be found here [pdf, 125kb].

This framework considers the agriculture and food sector, including primary agricultural production recorded, the inputs and products of industry based on agricultural raw material (primary crop whether foodgrain, horticulture, spices, plantation, ruminants and marine, oilseeds, fibres), agribusiness (processing in all its forms), supply chains connecting farmers and farmer producer organisations to primary crop aggregators, buyers, merchants, stockists, traders, consumers, as well as associated service providers. This approach is based on the connection between agricultural production and demand from buyers, processers and consumers along what is called the supply chain.

 

Water storage quantities in the 91 major reservoirs in the first week of April 2016. Blue bars are each reservoir’s full storage capacity (in billion cubic metres, bcm) and orange bars are the current storage at the time. Data from the Central Water Commission, Government of India.

If this framework is considered as existing in Bharat to a significant degree which influences crop cultivation choices, the income of cultivating household, the employment generation potential of associated service providers, then several sets of questions require answers:

* Concerning economic well-being and poverty reduction: what role does agricultural development need to play in promoting economic stability in rural (and peri-urban) regions thereby contributing to poverty reduction and how can the agrifood sector best contribute to jobs and higher incomes for the rural poor?

* Concerning food security: what role can agricultural and agro-industry development play in ensuring rural and urban communities have reliable access to sufficient, culturally appropriate and safe food?

* Concerning the sustainability of food producing systems: how should agriculture and agro-industry be regulated in a participatory manner so as to ensure that methods of production do not overshoot or endanger in any way (ecological or social) conservative carrying capacity thresholds especially in the contexts of climate change and resource scarcity?

When viewed according to the administrative and policy view that has prevailed in Bharat over the last two generations, there is a correlation between agricultural productivity growth and poverty reduction and this is the relationship the macro- economic and policy calculations have been based upon. Our central annual agricultural (and allied services) annual and five-year plan budget and state annual and five-year plan budgets have employed such calculations since the 1950s, when central planning began.

However the choices that remain open to us are considerably fewer now than was the case two generations (and more) ago when the conventional economic framework of the agriculture and food sector took shape.

Water and a district in Maharashtra

In this panel of maps the relationship between the district of Parbhani (in the Marathwada region of Maharashtra) and water is graphically depicted over time. The blue squares are water bodies, as seen by a satellite equipped to do so. The intensity of the blue colour denotes how much water is standing in that coloured square by volume – the deeper the blue, the more the water.

Water bodies consist of all surface water bodies and these are: reservoirs, irrigation tanks, lakes, ponds, and rivers or streams. There will be variation in the spatial dimensions of these water bodies depending on how much rainfall the district has recorded, and how the collected water has been used during the season and year. In addition to these surface water bodies, there are other areas representing water surface that may appear, such as due to flood inundations, depressions in flood plains, standing water in rice crop areas during transplantation stages. Other than medium and large reservoirs, these water features are treated as seasonal and some may exist for only a few weeks.

Click on this detail for a full size image (1.7MB) of the panel of fortnightly maps.

The importance of monitoring water collection and use at this scale can be illustrated through a very brief outline of Parbhani. The district has 830 inhabited villages distributed through nine tehsils that together occupy 6,214 square kilometres, eight towns, 359,784 households in which a population of 1.83 million live (1.26 rural and 0.56 million urban). This population includes 317,000 agricultural labourers and 295,000 cultivators – thus water use and rainfall is of very great importance for this district, and indeed for the many like it all over India.

The map of Parbhani district and its talukas, from the Census 2011 District Census Handbook.

This water bodies map for Parbhani district is composed of 18 panels that are identical spatially – that is, centred on the district – and display the chronological progression of water accumulation or withdrawal. Each panel is a 15-day period, and the series of mapped fortnights begins on 1 January 2015.

The panels tell us that there are periods before the typical monsoon season (1 June to 30 September) when the accumulation of water in surface water bodies has been more than those 15-day periods found during the monsoon season. See in particular the first and second fortnights of March, and the first fortnight of April. [Here is a good quality image of the census map, 968KB.]

During the monsoon months, it is only the two fortnights of June in which the accumulation of water in the surface water bodies of Parbhani district can be seen. The first half of July and the second half of August in particular have been recorded as relatively dry.

This small demonstration of the value of such information, provided at no cost and placed in the public domain, is based on the programme ‘Satellite derived Information on Water Bodies Area (WBA) and Water Bodies Fraction (WBF)’ which is provided by the National Remote Sensing Centre (NRSC), Indian Space Research Organisation (ISRO), Department of Space, Government of India.

For any of our districts, such continuous monitoring is an invaluable aid to: facilitate the study of water surface dynamics in river basins and watersheds; analyse the relationships between regional rainfall scenarios and the collection and utilisation of water in major, medium reservoirs and irrigation tanks and ponds; inventory, map and administer the use of surface water area at frequent intervals, especially during the crop calendar applicable to district and agro-ecological zones.

Lessons of monsoon 2015 for district India

With two weeks of the June to September monsoon remaining in 2015, one of the end-of-season conclusions that the India Meteorological Department (IMD) has spoken of is that four out of ten districts in the country has had less rainfall than normal.

This overview is by itself alarming, but does not aid state governments and especially line ministries plan for coming months, particularly for agriculture and cultivation needs, water use, the mobilisation of resources for contingency measures, and to review the short- and medium-term objectives of development programmes. [See ‘A method for a post-carbon monsoon’ for a recent discussion.]

The detailed tabulation (done for 15 weeks) is meant to provide guidance of where this may be done immediately – in the next two to four weeks – and how this can be done in future. The districts are chosen on the basis of the size of their rural populations (calculated for 2015). Thus Purba Champaran in Bihar, Bhiwani in Haryana, Rewa in Madhya Pradesh and Viluppuram in Tamil Nadu are the districts in those states with the largest rural populations.

In this way, the effect of rainfall variability, from Week 1 (which ended on 3 June) to Week 15 (which ended on 9 September), in the districts with the largest rural populations can be analysed. Because a large rural population is also a large agricultural population, the overall seasonal impact on that district’s agricultural output can also be inferred.

The distribution of the districts is: six from Uttar Pradesh; five each from Andhra Pradesh, Bihar, Chhattisgarh, Gujarat, Haryana, Jharkhand, Karnataka, Maharashtra, Madhya Pradesh, Odisha, Punjab, Rajasthan, Tamil Nadu and West Bengal; four each from Assam, Jammu and Kashmir, and Kerala; three from Uttarakhand; two from Himachal Pradesh; one each from Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura.

Using the new 11-grade rainfall categorisation, a normal rainweek is one in which the rainfall is between +10% more and -10% less for that week. The overview for this group of 100 districts, only 11 have had five or more normal weeks of rain out of 15 weeks. In alarming contrast, there are 77 districts which have had three or fewer normal weeks of rain – that is, more than three-fourths of these most populous districts. Half the number (51 districts) have had two, one or no normal weeks of rain. And 22 of these districts have had only one or no normal weeks of rain.

From this group of 100 most populous (rural population) districts Gorakhpur in Uttar Pradesh and Nagaon in Assam have had the most deficit rainweeks, tallying 13, out of the 15 tabulated so far. There are ten districts which have had 12 deficit rainweeks out of 15 and they are (in decreasing order of rural population): Muzaffarpur (Bihar), Pune and Jalgaon (Maharashtra), Surguja (Chhattisgarh), Panch Mahals and Vadodara (Gujarat), Firozpur (Punjab), Thiruvananthapuram (Kerala), Hoshiarpur (Punjab) and Mewat (Haryana).

Monsoon 2015 could be 93% with ifs and buts

The India Meteorological Department has just released it’s long-awaited forecast for the 2015 Indian monsoon. In terms of the quantity of rainfall over the duration of the monsoon season (June to September) the IMD has said it will be 93% of the ‘Long Period Average’. This average is based on the years 1951-2000.

What this means is the ‘national’ average rainfall over the monsoon season for India is considered to be 89 centimetres, or 890 millimetres. So, based on the conditions calculated till today, the ‘national’ average rainfall for the June to September monsoon season is likely to be 830 millimetres.

There are caveats and conditions. The first is that the 93% forecast is to be applied to the long period average for each of the 36 meteorological sub-divisions, and a ‘national average’ does not in fact have much meaning without considerable localisation. The second is that the forecasting methodology itself comes with a plus-minus caution. There is “a model error of ± 5%” is the IMD’s caution.

This first forecast and the model that the forecast percentage has emerged from are thanks to the efforts of the Earth System Science Organization (ESSO), under the Ministry of Earth Sciences (MoES), and the India Meteorological Department (IMD), which is the principal government agency in all matters relating to meteorology. This is what the IMD calls a first-stage forecast.

As with all complex models, this one comes with several considerations. The ESSO, through the Indian Institute of Tropical Meteorology (IITM, which is in Pune), also runs what it calls an ‘Experimental Coupled Dynamical Model Forecasting System’. According to this, the monsoon rainfall during the 2015 monsoon season (June to September) averaged over India “is likely to be 91% ±5% of long period model average”. (The IMD forecast is available here, and in Hindi here.)

This is a lower figure than the 93% headline issued by the IMD. This too should be read with care as there are five “category probability forecasts” that are calculated – deficient, below normal, normal, above normal and excess. Each is accompanied by a forecast probability and a climatological probability (see the table). The maximum forecast probability of 35% is for a below normal monsoon, while the maximum climatological probability is for a normal monsoon.

As before, time will tell and the IMD will issue its second long range forecast in June 2015. Our advice to the Ministry of Earth Sciences and to the IMD is to issue its second long range forecast a month from now, in May, and also to confirm these forecasts two months hence in June, when monsoon 2015 will hopefully be active all over the peninsula.

An erratic monsoon with late spikes

From the first week of June 2014 until the middle of September 2014, there have been floods and conditions near drought in many districts, but for India the tale of monsoon 2014 comes from individual districts and not from a national ‘average’ or a ‘cumulative’.

The weekly rainfall variation table for Maharashtra’s districts. The period of the last week of August and the first two weeks of September is the only period during which these districts received rainfall at or above normal. But overall, the second deficient category, coloured light rose, dominates (this table uses my modified monsoon measure methodology, see text for link)

This revealing chart tells some of that tale. It shows that for the first six weeks of monsoon 2014, most districts recorded rain below their normals for those weeks.

The lines are percentile lines; they tell us what percent of districts recorded how much rainfall in a monsoon week relative to their normals for that week. This chart does not show how much rain – it shows distance away from a weekly normal for districts.

The left scale is a percentage – higher percentages indicate how much above normal districts recorded their rainfall, negative numbers show us how much below normal their rainfall was.

The dates (the bottom scale) are for weeks ending on that date for which ‘normals’ and departures from normal were recorded. The P_01 to P_09 lines are the percentiles (10th to 90th) of districts in every week.

The typical IMD map of ‘normal’ rainfall measured by the meteorological sub-divisions. The detailed weekly tables give us a very different picture.

The district weekly normal is an important measure for matters like sowing of crop and issuing water rationing instructions in talukas and blocks. In the week ending 23 July for example, we see that the 60th percentile line spiked above normal, and this means that in that week only four out of ten districts all over India received the amount of rain it should have based on the average of the last 50 years.

The districts overview chart is distilled from the detailed weekly tables I have assembled (see the image of the Maharashtra table). For the whole country, what the districts tell us about the monsoon so far is a very much more detailed and insightful tale than the typical offering by the Meteorological Department (see India sub-divisional map). These weekly district tables are coded using my modified monsoon methodology, geared towards aiding decisions for local administrations especially for prolonged arid conditions leading to drought.
