Since climate-related crop failure has activated a shift in cropping system, creating adaptation and mitigation methods is essential.

On the outset, Cheriyan’s two-acre cardamom farm is a thriving inexperienced panorama underneath the cerulean sky. However on nearer inspection, you will note the wilted shoots and broken pods — byproducts of an erratic climate.

The Malayalam month of Edavam has come to an finish with none regular downpour, the dry spell stretching all by the third week of June apart from some delicate, dwindling drizzles. Crops miss that wealthy monsoon hue and farmers in Idukki, a district that recorded a big rain deficit of 69% through the June 1-22 interval, are bracing for a attainable crop failure.

“It is for the primary time we’re experiencing a virtually dry monsoon whereas the temperature retains rising. A delayed or failed monsoon will have an effect on the capsule formation and the yield will dip,” says the 67-year-old from Kumily.


Cardamom is one among the many many thermosensitive crops hit by rising mercury ranges, change in climate patterns and excessive weather conditions, including to the agrarian misery within the State. Farmers complain that the inconsistent rain sample is inflicting crop loss and delayed flowering, whereas the aberrancy in temperature and humidity is triggering pest assaults. The autumn in yield has hit their livelihood and at current a lot of them are gazing an unsure future.

“Nearly all of residents in our village are depending on the only crop of cardamom and it is virtually not possible for us to change. I’ve been cultivating cardamom for the final 22 years and the altering local weather is posing a severe risk to us. We’ve got been farmers for generations and at current we’re in the course of a serious disaster,” provides Mr. Cheriyan, as his cousin Shaji agrees.

“There was a gentle rise in common daytime temperature. We used to develop orange previously, however we needed to give up after the spike in temperature began impacting the fruition of orange groves. The high-range local weather is not any extra the identical and the cardamom farmers are having a tough time,” factors out Mr. Shaji.

Based on Suresh Kumar, a farmer from Kattappana, it began with the floods of 2018 when incessant rain precipitated widespread crop injury. “After the primary floods, the proportion of rain has by no means been the identical and our harvest cycle additionally modified. Through the month of June we add manure to expedite the germination of charams (panicles) and if there is no such thing as a rain, the expansion will decelerate. Although the crops presently look wholesome because of the pre-monsoon rain, the yield will probably be very poor,” he says.

He provides that whereas 250 kg of dried cardamom is the typical yield you normally get from one acre, now it has come all the way down to 160-170 kg. Although there was a substantial dip in yield from particular person holdings, the general manufacturing of the spice has elevated as a result of space extension over the last 5 years.

“In 2017-18 there was a pointy rise in demand and the costs crossed Rs4,000 per kilogram. With the costs going by the roof, many farmers stopped cultivating different crops and planted cardamom anticipating bumper returns. As manufacturing and provide elevated, costs got here all the way down to Rs680, which hardly covers the manufacturing value. Whereas enormous estates that domesticate a spread of crops and generate enormous volumes of cardamom will not be a lot affected, small-scale farmers are struggling,” he provides.

Pest and pesticide use

Pointing to the deformed pods fallen from the plant, Child says pest assaults have develop into extra frequent with the change in local weather. “We’re unable to regulate these pests with very excessive resistance and as they simply adapt to adjustments. We’re compelled to spray pesticides to salvage what’s left of our crop,” provides the farmer from Udumbanchola. He confirms that they make common journeys to pesticide sellers to purchase what is known as ‘vesham’ (poison) in native parlance.

“It might be extremely poisonous and we do not know if it is authorized or whether or not the ratio is right. We additionally worry that they could destroy the soil in the long term, however we have no different choices since we hardly get any help from authorities. We lack some other means to manage,” he provides.

Whereas local weather change is an element impacting the crop, this indiscriminate use of chemical pesticides may give rise to a spate of antagonistic consequence, says Muthusami Murugan, Professor and head of the Cardamom Analysis Station at Pampadumpara, Idukki. “Local weather change has introduced a variety of variations in rainfall behaviour together with depth and wet days on annual and seasonal scale. This has had a constructive impact on pest strain and affected the cardamom yield. However high-intensity chemical use will have an effect on the expansion, growth, flowering and capsule setting of cardamom underneath the altering weather conditions within the Indian cardamom hills,” he says.

Cashew nut

The Aralam Farming Company Kerala Restricted in Kannur, which produces round 90% of the uncooked cashew nut in Kerala, noticed a report fall in yield this season. Unfold throughout 350 hectares, Aralam orchards produce high-quality nut that enjoys an enormous demand within the inside market. “Our whole yield over the last season was 184 tonnes and this time it got here all the way down to 90, which implies there was greater than 50% dip in manufacturing,” says S.Bimalghosh, managing director of the farm.

Whereas extra rainfall through the flowering season affected the fruit setting course of, the wayward climate additionally tousled the standard of the produce. “As a result of steady rain the nuts began sprouting on the tree and even the fallen ones started to germinate inside a few days. We misplaced round 1500 kg of nut as a result of sprouting induced by unseasonal rain,” he provides.

In a bid to save lots of the sinking cashew sector, the State authorities had launched an intensive plantation drive distributing round 25 lakh high-yielding grafts during the last 5 years. At current the cultivation is unfold over one lakh hectares of land and a surge in annual nut manufacturing was additionally reported over the last season.

“However the image has modified this time and the farmers have reported an unprecedented dip in manufacturing. The rain that continued until November precipitated the flowers to fall and the rise in temperature throughout December-January was additionally not beneficial for the crop. There was a constant enhance in manufacturing until 2018, however we’re seeing variations over the last couple of years,” says Shirish Kesavan, particular officer (cashew) and chairman, Kerala State Company for the enlargement of Cashew Cultivation (KSACC).

Spike in pest inhabitants

Variations in temperature and relative humidity usually facilitate the emergence of recent pests and ailments, leaving many crops inclined to assaults and outbreaks. “Whereas these adjustments will speed up fungal an infection in some crops, you will note minor pests turning into main pests for some. With the rise in temperature, the variety of lifecycles will enhance and there will probably be a spike in pest inhabitants. Sooner or later, controlling these pests and ailments will probably be a key concern,” says P. Shajeesh Jan, Division of Agricultural Meteorology, Regional Agricultural Analysis Station (RARS), Wayanad.

Whereas pure enemies are multiplying within the heat climate situations, excessive rainfall occasions have been wiping out soil nutrient reserves, producing a unfavorable affect on the crops. “Extreme rainfall will decrease soil fertility and switch it acidic. With the highest soil washed away there will probably be a depletion in natural matter,” he provides.

Based on a examine carried out by the Indian Cardamom Analysis Institute underneath the Spices Board and Faculty of Local weather Change and Environmental Science underneath Kerala Agricultural College, thermosensitive crops like cocoa, black pepper, cardamom, espresso and tea could also be underneath risk because the temperature vary throughout the Cardamom Hill Reserve (CHR) of Idukki district is growing. It additionally finds a rise within the floor air temperature throughout the State and requires proactive measures to alleviate dangers associated to the standard and amount of the crops. Whereas poor rain impacts pepper pollination, resulting in a dip in manufacturing, change in humidity ranges will affect the scale and high quality of espresso bean.

A worrying shrinkage in paddy farming space is without doubt one of the main finds within the examine on ‘Local weather change and cropping sample of plantation crops and spices in Kerala’. “The rise in space underneath banana, areca nut and rubber is usually on the expense of paddy fields. Rubber has encroached on an increasing number of areas of the State. The paddy cultivating areas of the excessive ranges have both paved the way in which for rubber cultivation or to pineapple, areca nut, banana and different seasonal crops,” it says.

For the reason that onset, distribution and behavior of the monsoon have modified through the years, virippu (wet season) paddy, which is closely depending on monsoon, is underneath extreme risk in lots of components. “Since virippu paddy is principally a rainfed crop, farmers is not going to have assets for supplemental irrigation. This yr water was launched from the Malampuzha dam to save lots of the crop in Palakkad which has the most important acreage of paddy farms. For the reason that first crop is all the time rainfed, we irrigate the farms solely through the mundakan season (second crop) from October to December. Water deficit is a serious problem for paddy and this variation in sample has altered our conventional crop calendar,” says climatologist Gopakumar Cholayil.


Paddy farmers are a anxious lot since incessant summer season showers had wreaked havoc in Kuttanad, destroying the harvest-ready puncha crop in April 2022. “Heavy downpours began at first of the harvest season and inside no time the paddy polders had been inundated. It was virtually not possible to empty the water and the crop began rotting in entrance of our eyes. Persevering with crop failure and mounting money owed are making our life depressing,” says Purushan, a farmer from Alappuzha.

Whereas many farmers couldn’t reap the harvest, those that managed had been unable to move it and the standard of the produce was very mediocre at many polders. “Furthermore, heavy summer season rainfall aggravated bacterial leaf blight illness in paddy and this yr a variety of farmers needed to undergo yield losses as a result of that,” provides Mr.Cholayil.

Extended dry spells, delayed monsoons, depth shifts and cloudbursts – all of them level to the truth that the rainfall situation within the State has modified. In January 2021 Munnar recorded sub-zero temperature and the chilly wave had a devastating affect on the vegetable tracts in Vattavada.

“In Marayur, sugarcane farmers misplaced a complete season and it is a clear-cut instance of the local weather change,” he observes. Through the time Kerala witnessed an exceptionally excessive rainfall of 105.5 mm in opposition to the traditional of 11.0 mm. “In Idukki daytime temperature is rising whereas night time temperature is falling. In the long term, this widening hole in temperature vary will adversely have an effect on the high-range crops rising in forest-agro ecosystems,” he says. Because the shift in rainfall and temperature developments have gotten extra pronounced, farmers are compelled to go for crops which have comparatively greater resilience.

Since climate-related crop failure has activated a shift in cropping system the place non-foodgrain crops are steadily changing foodgrain crops, creating adaptation and mitigation methods is essential. “We can’t formulate the technique with out constant research. Our analysis ought to focus extra on spell evaluation as a substitute of month-to-month or yearly statistics. Heavy rain inside a brief span of time, variations in high-range temperature, excessive climate occasions — all these point out that the local weather is altering and it will probably have a severe affect on the meals safety of the State. We want short-term and long-term programmes as a substitute of in search of quick-fixes throughout climate-related contingencies. A joint effort of consultants from varied streams is essential for creating the technique,” says Mr. Cholayil.
