Mangrove Forests: Presence and Significance
Mangrove forests comprise the interface between wetlands and sea grass meadows along a vast expanse of tropical shorelines all over the world.
They also occur along bays, estuaries or mouths of rivers by these shores.
Mangroves are present worldwide on various shorelines between approximately 25°N and 25°S latitude.
Mangrove forests are one of the greatest sources of biodiversity on this planet.
They have a rich underwater component, a surface component and an aerial component.
Mangrove communities include fish, insects, shellfish, birds of many species, saltwater crocodiles, monkeys, algae and fungi.
Many organisms, especially fish, spend their early years in the protection of the mangroves and their intricate below and above-ground root systems.
How are Mangrove Forests Useful?
Mangroves, along with sea grasses and wetlands, comprise the ‘blue carbon’ ecosystem of stored carbon in sediments along many tropical and subtropical coastal zones.
Their complex aerial and submerged root systems moderate current flows and the canopies moderate wind flow — they are the interface between the wetlands and sea grass communities for the continental flow of water and solutes into the ecosystem.
Mangroves also supply fuelwood and other forest products, like food and medicine, for people.
And, in addition to the nutrition they give us, mangroves protect us — along with other trees and forests, mangroves sequester a sizeable amount of carbon to offset greenhouse gas emissions created by human activities.
When mangrove trees die of natural causes, they generally fall into the sea and the carbon may be stored in the sediment on the sea floor for long periods of time.
Types of Mangrove Trees
The term ‘mangrove’ is used to refer to a whole community of trees and shrubs, which are not closely related.
The Mangrove trees have all adapted to harsh coastal environments of saline, brackish waters and low oxygen conditions.
There are over 100 species of trees and shrubs designated as mangroves.
However, there are three classic groups of mangroves — the red mangroves (Rhizophoraceae), the black mangroves (Acanthaceae) and the white mangroves (Combretaceae).
The current state of the mangroves
South Asia houses some of the most extensive areas of mangroves globally, while Indonesia hosts one-fifth of the overall amount.
India holds around 3 percent of South Asia’s mangrove population.
Besides the Sundarbans in West Bengal, the Andamans region, the Kachchh and Jamnagar areas in Gujarat too have substantial mangrove cover.
However, infrastructure projects — industrial expansion and building of roads and railways, and natural processes — shifting coastlines, coastal erosion and storms, have resulted in a significant decrease in mangrove habitats.
Between 2010 and 2020, around 600 sq km of mangroves were lost of which more than 62% was due to direct human impacts, the Global Mangrove Alliance said in its 2022 report.

Crisis in Ukraine and Gaza Impacts Global Fertilizer Supply, Pressuring India to Boost Production
Context:
As the conflict persists in Ukraine and Gaza, there is growing concern over potential price increases for key components used in petroleum-based chemical fertilizers. In light of these challenges, Nicholas Sitko, a Senior Economist at the Food and Agriculture Organization, emphasized the necessity for India to enhance its fertilizer production capabilities. This urgency is underscored by a statement from the Agriculture Minister of Uttar Pradesh, India’s largest foodgrain-producing state, noting that the state has only ten days’ worth of fertilizer stocks left. This comes at a critical time as the sowing of winter rabi crops, which rely heavily on fertilizers like Diammonium phosphate (DAP) and NPK (Nitrogen, Phosphorus, and Potassium), is underway across India’s wheat-growing states.

What is the current import fertilizer import scenario?
Though the latest data on import is yet to be made available by the Ministry, the Standing Committee of Parliament on Chemicals and Fertilizers, in August 2023, tabled a report on ‘Planning for Fertilizers Production and Import Policy on Fertilizers Including GST and Import Duty Thereon’ in both the Houses.
It expressed concern that the “production capacity of fertilizers does not commensurate with its demand/requirement and, therefore, the gap between demand and supply is met through imports.”
According to the report, about 20% of the domestic requirement of urea, 50-60% of the domestic requirement of DAP, and 100% of the domestic requirement of Muriate of Potassium (MOP, or Potash) is met through imports.
How has India’s fertilizer production changed?
In 2021-22, India’s yearly consumption of all major chemical fertilizers was approximately 579.67 lakh metric tonnes (LMT), comprising 341.73 LMT of urea, 92.64 LMT of DAP, 23.93 LMT of MOP, and 121.37 LMT of NPK.
In 2020-21, the total consumption of fertilizers was about 629.83 LMT. The country produced 435.95 LMT of chemical fertilizers in 2021-22, resulting in a shortfall of 143.72 LMT relative to demand.
While MOP is not produced here, in 2021-22, India produced 250.72 LMT of urea, 42.22 LMT of DAP, 89.67 LMT of NPK, and 53.34 LMT of Single Super Phosphate (SSP). Total production in 2014-15 was 385.39 LMT, indicating an increase of only about 50 LMT over seven years.
In the case of Urea, the most consumed fertilizer, in 2019-20, the production was 244.58 LMT and the use was 336.96 LMT. In 2020-21, the country produced 246.05 LMT of urea and consumed 350.51 LMT. In 2021-22, the figure was 250.72 LMT and 341.72 LMT, respectively.
The Centre allocated ₹ 1.79 lakh crore as fertilizer subsidy under the Budget estimates for 2023-24.
Out of this, for indigenous P&K Fertilizers, the subsidy amount was ₹25,500 crore and ₹18,500 crore for imported P&K Fertilizers.
For indigenous Urea, the subsidy was ₹1,04,063.20 crore while the subsidy for imported urea was ₹ 31,000 crore.
Current Geopolitical Impact
Ukraine and Gaza Crises: The conflict in Ukraine and instability in Gaza have disrupted global markets, particularly affecting the price of oil, a key input for fertilizer production.
Impact on India: As noted in the Lok Sabha, India heavily relies on fertilizer imports from countries like China, Russia, Saudi Arabia, UAE, Oman, Iran, and Egypt. The ongoing conflicts in Ukraine and tensions in West Asia pose risks to these imports, potentially leading to shortages and higher prices.
Strategic Responses for India
Enhancing Domestic Production: Increasing the production capacity of domestic fertilizer plants can reduce India’s dependence on imports. Recent initiatives have added significant urea production capacity.
Alternative Farming Practices: Experts suggest shifting towards natural farming methods and using innovative products like nano urea to decrease dependency on traditional, import-heavy fertilizers.
Investment in Fertilizer Sector: The Standing Committee of Parliament advocates for policies that stimulate investments across public, cooperative, and private sectors in fertilizer production.
Investment and Policy Shifts
New Investment Policy: Introduced in 2012, this policy has facilitated the establishment of new urea plants and the revival of old units, thereby bolstering domestic production capabilities.
Future Outlook: The government’s continued focus on enhancing local manufacturing infrastructure and adopting sustainable agricultural practices is crucial for securing India’s fertilizer needs amid global uncertainties.

Greenhouse Gas Bulletin
Highlights from the Latest Report
Greenhouse Gas Bulletin
Publication and Purpose:
The World Meteorological Organization (WMO) has published the Greenhouse Gas Bulletin annually since 2004. This report is essential for tracking changes in the concentrations of key greenhouse gases (GHGs) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) globally.
It is designed to provide scientific data for policy-makers, particularly in preparation for the UN Climate Change Conferences (COP).
Key Insights and Data:
The Bulletin reports on the globally averaged surface concentrations of these gases, offering comparisons with previous years and pre-industrial levels.
It also examines the role these gases play in radiative forcing, a measure of their impact on Earth’s energy balance and, consequently, on climate.
Highlights from the Latest Report
Concentration Levels in 2023:
Carbon dioxide levels reached 420 parts per million (ppm), methane levels at 1934 parts per billion (ppb), and nitrous oxide at 336.9 ppb.
These levels underline significant ongoing increases in greenhouse gases due to human activities such as fossil fuel combustion and cement production.
Impacts and Contributions:
CO2 remains the dominant greenhouse gas, responsible for approximately 64% of the anthropogenic warming effect.
The variability in CO2 levels is influenced annually by phenomena such as the El Nino–Southern Oscillation, which affects global carbon cycles and atmospheric concentrations.
Methane, which is particularly effective at trapping heat in the atmosphere, contributes about 16% to the warming impact of GHGs but stays in the atmosphere for a shorter duration compared to CO2.
Nitrous oxide, besides contributing to warming, also plays a role in ozone depletion, accounting for about 6% of the warming impact from GHGs.
Long-term Trends and Effects:
Since 1990, there has been a 51.5% increase in radiative forcing by long-lived greenhouse gases, with CO2 accounting for about 81% of this increase, highlighting the significant role of human activities in climate change.
