Importance of tracking forest cover changes.
The importance of tracking forest cover changes in North 24 Parganas cannot be overstated. Forests play a vital role in maintaining ecological balance and providing environmental services such as water regulation, soil conservation, and carbon sequestration.
Monitoring forest cover changes is crucial for understanding the impacts on climate change, desertification, soil erosion, and flooding. It also aids in developing sustainable forest management strategies that restore forest resources and ecosystem services.
As such, keeping a close eye on the forest dynamics of North 24 Parganas is essential for preserving its rich biodiversity and ensuring the well-being of its ecosystems for future generations.
The State of Primary Forests
In the span of two decades, from 2002 to 2023, North 24 Parganas witnessed the loss of less than 1 hectare of its humid primary forest.
This figure, while seemingly small, represents a significant change in an ecosystem that is both delicate and crucial for biodiversity.
Primary forests, often referred to as old-growth forests, are vital for maintaining ecological integrity as they house complex networks of flora and fauna that have evolved over centuries.
The reduction in the overall size of humid primary forests in North 24 Parganas was less than 0.1% during that time. Even though this percentage is tiny, it’s important to understand that any reduction in primary forest is significant.
These forests are irreplaceable repositories of genetic diversity and play a pivotal role in carbon storage, water cycle regulation, and providing refuge for countless species.
The conservation of these primary forests is not just about preserving trees; it’s about safeguarding the future of our planet’s climate and the myriad of life forms that depend on these forests for survival. It is a call to action for sustainable management and protection policies that will ensure these forests continue to thrive for generations to come.
Tree Cover Trends
The analysis of tree cover trends in North 24 Parganas from 2001 to 2023 reveals a loss of 37 hectares of tree cover. This loss, while numerically modest, signifies a broader environmental impact on the region’s landscape and its ecological functions.
The corresponding 0.11% decrease in tree cover might seem negligible at first glance, but it is a part of a larger narrative of habitat fragmentation and ecosystem degradation that can have far-reaching consequences for biodiversity and local climate regulation.
The 44.2 kilotonnes (kt) of COâ‚‚ emissions from this tree cover loss is a crucial number because it shows the carbon footprint linked to deforestation. To understand this better, worldwide information indicates that losing primary forests can lead to substantial carbon emissions.
For example, the destruction of primary rainforests in the tropics in 2022 resulted in 2.7 gigatonnes (Gt) of carbon dioxide emissions, which is equal to India’s yearly fossil fuel emissions. While the emissions from North 24 Parganas are much smaller in scale, they contribute to the cumulative global impact of deforestation on climate change.
The tree cover loss in North 24 Parganas also reflects the challenges faced by urban expansion and land-use changes. Studies have shown that urban growth dynamics can lead to a significant loss of vegetation and other non-urban/built-up areas.
This is particularly relevant for the district, which is part of the rapidly urbanizing Kolkata metropolitan area. The transformation of agricultural land into built-up areas and the decrease in water bodies and vegetation due to increasing urbanization are trends that have been observed in the region.
A Closer Look at the Numbers
The net change in tree cover in North 24 Parganas from 2000 to 2020 was a gain of 5.55 kha (5.3%). This positive change indicates a trend of recovery and growth in the district’s tree cover over the two decades.
Such a gain is significant as it reflects the efforts towards reforestation, afforestation, and natural regeneration of forests in the area. The increase in tree cover is crucial for enhancing biodiversity, improving air and water quality, and contributing to the fight against climate change by sequestering carbon dioxide.
When comparing the tree cover gain in North 24 Parganas to other districts in West Bengal, it is evident that there is a varied pattern of forest cover change across the state. For instance, districts like Bankura, Paschim Medinipur, Purulia, and Birbhum have recorded a rise in forest cover.
Specifically, Purulia has shown significant forest cover gains, which is notable given its geographical and climatic conditions.
Conversely, districts like South 24 Parganas, Uttar Dinajpur, Murshidabad, and Howrah have experienced a decline in forest cover.
This comparison highlights the diverse environmental challenges and conservation efforts in different parts of West Bengal. It underscores the need for tailored strategies that address the unique ecological needs of each district.
The tree cover gain in North 24 Parganas is a positive development, but it also serves as a reminder that continuous monitoring and sustainable management practices are essential to maintain and improve the forest cover in the region and across the state.
Land Cover Composition of 24 PGS (N)
In the year 2000, the land cover in North 24 Parganas comprised natural forests, plantations, and various other land uses, creating a diverse landscape.
The natural forests, which are critical for maintaining ecological balance and supporting a diverse range of species, covered an area of 32.2 kha.
Plantations, which include managed resources of economically important trees, spanned across 2.99 kha.
The remaining land cover was predominantly composed of other land uses, including agricultural fields, urban areas, and water bodies, accounting for 546 kha.
The percentage of land with more than 30% tree cover in North 24 Parganas was 5.5% as of 2000. This level of tree cover is essential for providing habitat for wildlife, maintaining soil health, and regulating the local climate. It also plays a significant role in the socio-economic aspects of the region, supporting livelihoods through forestry and agriculture.
It’s important to note that the land cover composition has likely evolved since 2000 due to various factors such as urbanization, agricultural expansion, and natural resource management practices.
These changes have implications for the sustainability of local ecosystems and the services they provide to the community. Therefore, continuous monitoring and adaptive management strategies are crucial to ensure the conservation and enhancement of the region’s land cover for future generations.
| Land Cover Type | Area (kha) | Percentage of Total Land Cover |
|---|---|---|
| Natural Forests | 32.2 | Approx 5.54 % |
| Plantations | 2.99 | Approx 0.51 % |
| Other Uses (agricultural fields, urban areas, and water bodies) | 546 | Approx 93.95% |
Drivers of Forest Change
The impact of fires on tree cover in North 24 Parganas, as well as other regions, is a significant concern for forest conservation efforts.
Fires, whether natural or human-induced, can lead to substantial loss of tree canopy and biodiversity, and contribute to carbon emissions which exacerbate climate change.
In the context of North 24 Parganas, the district lost 2 hectares of tree cover from fires between 2001 and 2023, with the year 2001 experiencing the most tree cover loss due to fires.
The year 2001 was particularly notable for tree cover loss due to fires in North 24 Parganas, with less than 1 hectare lost to fires — accounting for 25% of all tree cover loss for that year.
This highlights the vulnerability of forests to fire-related disturbances and the importance of implementing effective fire management strategies.
It is crucial to understand the underlying causes of these fires, which can range from natural factors such as lightning strikes to human activities including agricultural burning, land clearing, and accidental ignitions.
Globally, from 2001 to 2019, 119 million hectares of tree cover were lost due to fires. In India, fires caused 1.6% of tree cover loss between 2001 and 2022, with the maximum tree cover loss due to fires recorded in 2008.
This data underscores the need for comprehensive fire management plans that include prevention, early detection, and rapid response to minimize the impact of fires on forests.
In conclusion, The case of North 24 Parganas in 2001 serves as a reminder of the ongoing challenges in forest conservation and the need for sustained efforts to protect these vital natural resources.
