  • The Maharashtra climate action plan yields huge disappointments as it failed to recognize crucial issues in its implementation.
  • The issues like air pollution and damage through thunderstorms and lightening were ignored.
  • The plan only focused on six major factors.

Mumbai, Jan 1: Eight years after the Centre’s direction to formulate a state action plan on climate change, and seven years after awarding the contract for a comprehensive vulnerability assessment study, the Maharashtra cabinet has finally adopted a plan on climate change.

Titled ‘Assessing Climate Change Vulnerability and Adaptation Strategies for Maharashtra: Maharashtra State Action Plan on Climate Change, and prepared by The Energy and Resources Institute (TERI), the action plan assesses vulnerability of the state to changing climate and outlines broad and ambitious strategies for building a climate-resilient future.

The action plan, built on high resolution modelling for which TERI entered into a partnership with the UK Met Office, projects changes in temperature and rainfall across the state at a resolution of about 25 km by 25 km for time periods 2030s, 2050s and 2070s — with the average climate during 1970-2000 as the model’s baseline.

An important component of the action plan is the Macro Level Vulnerability Index based on 19 indicators, which has identified the most vulnerable districts in Maharashtra: Nandurbar is the most climate change-vulnerable district, followed by Dhule and Buldhana. Satara is regarded as the least vulnerable district. Ratnagiri and Sindhudurg are also considered less vulnerable to changes in the climate. The state government has announced setting up a panel of experts to oversee the implementation of the report.

But, meteorologists and environment experts aren’t satisfied with the action plan. “The state has taken considerable time to come up with its adaptation plan on climate change. But the plan misses out on some crucial weather events, such as thunderstorm and lightning, that are linked to climatic changes. Air pollution, an important environment factor, is also missing from the plan,” said Akshay Deoras, Nagpur-based meteorologist.

Ashok Jaswal, former scientist with the India Meteorological Department (IMD), Pune, stresses that an effective state action plan should include all direct and indirect climatic parameters.

“Air pollutants are aerosols and have their own different properties. Some are salt-based, whereas others are carbon-based, or dust, or smoke. Some reflect solar radiation, whereas others trap heat,” he said. “These aerosols influence cloud formation, rainfall and the overall climate, and must be a part of the state action plan on climate change.”

Broadly speaking, the plan discusses the impact of climate change on six sectors — agriculture, water resources, health, forests and biodiversity, livelihoods, and energy and infrastructure. It also makes projections for rainfall and temperature in the state; and assesses the future sea level rise. A section in the plan is dedicated to extreme rainfall, flooding and adaptation in the Mumbai Metropolitan Region.

The document shows that temperature and rainfall are projected to increase all over the state with some regional variations. Amravati division (Vidarbha region) and Aurangabad division (Marathwada region) are going to experience greater rise in annual mean temperatures than other parts of the state.

The projected increase in annual mean temperature for Amravati is expected to be 1.44-1.64 degree C, 2.2-2.35 degree C, and 3.06-3.46 degree C in 2030s, 2050s and 2070s, respectively. For the same time periods, the projected annual mean temperature increase for Aurangabad division is 1.44-1.56 degree C, 2.15-2.3 degree C, and 3.14-3.38 degree C, respectively. An increase in temperature is likely to lead to a decrease in yields for some crops, such as rice, sorghum and cotton.

Minimum temperature is also projected to increase, particularly in the divisions of Konkan, Pune and Nashik, which could have an adverse impact on crops sensitive to high night temperatures in the reproductive phase, such as grain growth in rice or tuberisation in potatoes, warns the state action plan.

The action plan notes that an increase in temperature will be conducive to malaria-transmitting mosquitoes in eastern and coastal (Thane and Raigad regions) Maharashtra in 2030s. By the 2050s, a faster rate of parasite development will take place in Aurangabad, Jalna and Nashik districts.

Since a warmer atmosphere has a higher capacity to hold water vapour, it will lead to intense rainfall events with longer dry or low rainfall spells in between. Extreme rainfall is projected to increase in all regions of the state with greater increases in the northern parts of the state.

Meanwhile, parts of south-central Maharashtra are projected to experience more dry days in the 2030s as compared to the baseline. These districts of Marathwada are already prone to recurring droughts and infamous for farmers’ suicides.

“The findings… clearly describe the adverse impacts of climate change on all regions of the state. The report shows the worrying trend of an increase in extreme weather events and heavy precipitation days,” said Parineeta Dandekar, associate co-ordinator of the South Asian Network on Dams, Rivers and People.

“Increased rainfall will lead to heavy flooding, which will have a direct bearing on the state’s water infrastructure. But, the action plan fails to elaborate upon ways to manage the water infrastructure in times of climate change.”

Lightning is listed as a state-specific disaster in Maharashtra, but the state action plan makes no mention of lightning, which is linked to climatic changes. “Rising temperature means more evaporation and high moisture content in the atmosphere, which leads to more thunderstorm activity and an increased incidence of lightning,” explained Jaswal.

A recent study, ‘Distribution of Lightning Casualities over Maharashtra’, has examined lightning deaths in the state between 1979 and 2011 and found 2,363 casualties from 455 lighting events. On an average 72 casualties per year have been reported with significant increasing trend.

“It is shocking that in spite of so many lives being lost each year due to lightning, the state action plan does not even mention the terms thunderstorm and lightning. Unless the plan acknowledges these weather events, how will the state government manage such disasters?” questioned Deoras.

The action plan does take note of the adverse impacts of hailstorm on horticulture crops in the state. For instance, it notes that hailstorms destroyed the grape crop in 2008-09. In 2010, almost 15 percent of the orange crop was destroyed due to rising heat and untimely hailstorm. But it fails to provide pointed information on ways to minimise impact on crops.

The action plan also makes no mention of air pollution. “Not including air pollution in the state climate action plan is a major drawback and the same must be rectified at the earliest,” said Jaswal.

Dandekar stresses on the need for translating action points into swift action. “The recommendations should not remain on paper, but must be included in the various state policies for immediate implementation,” she said. Deoras recommends setting up of a committee to reframe the action plan, by including the above-mentioned points, and then working towards the plan’s implementation by providing specific directions.

Children and young adults living in polluted megacities are at increased risk of developing Alzheimer’s, a debilitating brain disease characterised by memory loss, a new study has warned.

“Alzheimer’s disease hallmarks start in childhood in polluted environments, and we must implement effective preventative measures early,” said one of the researchers Lilian Calderon-Garciduenas from University of Montana in the US.

“It is useless to take reactive actions decades later,” Calderon-Garciduenas said. The findings, published in the Journal of Environmental Research, indicate that Alzheimer’s starts in early childhood, and the disease progression relates to age, pollution exposure and status of Apolipoprotein E (APOE 4), a well-known genetic risk factor for Alzheimer’s. The researchers studied 203 autopsies of Mexico City residents in the US ranging in age from 11 months to 40 years.

Metropolitan Mexico City is home to 24 million people exposed daily to concentrations of fine particulate matter and ozone above US Environmental Protection Agency standards. The researchers tracked two abnormal proteins that indicate development of Alzheimer’s, and they detected the early stages of the disease in babies less than a year old.

The scientists found heightened levels of the two abnormal proteins — hyperphosphorylated tau and beta amyloid — in the brains of young urbanites with lifetime exposures to fine-particulate-matter pollution (PM2.5).

They also tracked APOE 4 as well as lifetime cumulative exposure to unhealthy levels of PM2.5 — particles which are at least 30 times smaller than the diameter of a human hair and frequently cause the haze over urban areas. The researchers found hallmarks of the disease among 99.5 percent of the autopsies they examined in Mexico City. In addition, the findings showed that APOE 4 carriers had a higher risk of rapid progression of Alzheimer’s.

The researchers believe the detrimental effects are caused by tiny pollution particles that enter the brain through the nose, lungs and gastrointestinal tract, and these particles damage all barriers and travel everywhere in the body through the circulatory system.

The authors noted that ambient air pollution is a key modifiable risk for millions of people across the globe. “Neuroprotection measures ought to start very early, including the prenatal period and childhood,” Calderon-Garciduenas said. “Defining pediatric environmental, nutritional, metabolic and genetic risk-factor interactions are key to preventing Alzheimer’s disease,” she added.
