ACCELERATING
SUSTAINABLE GROWTH

In the relentless struggle against climate change, two unsung heroes have emerged from the Earth's embrace - land and forests. While these resources may seem unassuming, they wield unparalleled influence in mitigating the colossal challenge posed by rising global temperatures. Let's delve into the intricate ways in which land and forests play a pivotal role in combating climate change.

The Carbon Dilemma: A Tale of Sinks and Sources

At the heart of the matter lies carbon dioxide (CO2), the notorious greenhouse gas responsible for trapping heat in our atmosphere. Forests, trees, and grasses collectively act as nature's "sinks" for CO2, heroically absorbing a significant portion of this harmful gas emitted through human activities. This process, known as carbon sequestration, is akin to Earth's own carbon capture and storage technology.

Yet, like a multifaceted puzzle, this story isn't solely one of absorption. The land also serves as a source of CO2 emissions, a consequence of activities such as deforestation and land degradation. These actions release stored carbon back into the atmosphere, contributing to the alarming rise in CO2 levels. Thus, understanding the delicate balance between land as a sink and a source is crucial in comprehending its role in the climate equation.

The Dance of Estimation and Uncertainty

Scientists shoulder the responsibility of deciphering the intricate dance between land, forests, and carbon. They endeavor to estimate the net impact of these natural systems on carbon emissions. This intricate task is no easy feat, considering the myriad variables at play - from diverse forest ecosystems to ever-changing human interventions

Enter climate change, a disruptor that further complicates this intricate ballet. Escalating temperatures place stress on forests, rendering them susceptible to devastating wildfires. As landscapes transform, their ability to sequester carbon is jeopardized. In essence, forests, once reliable carbon sinks, are challenged by the very crisis they seek to alleviate.

Peering Through the Numbers: Insights from Research

Research, as a beacon of understanding, illuminates the intricate nuances of this relationship. A study published in Nature Climate Change (2021) unveiled a striking revelation. Over the span of two decades, global forests sequestered twice as much carbon dioxide equivalent (CO2e) as they emitted. This delicate balancing act, led by Nancy Harris and her team at the World Resources Institute, demonstrated that forests annually absorbed approximately 15.6 billion tons of CO2e, overshadowing emissions from disturbances.

In parallel, the Intergovernmental Panel on Climate Change (IPCC) Special Report on Climate Change and Land 2019 corroborated this narrative. Land use, it indicated, contributed to 13% of human-induced CO2 emissions while concurrently acting as a net sink of around 11.2 billion tons CO2 per year. This net carbon absorption equated to a staggering 29% of total CO2 emissions during the same period.

The Green Road Ahead: Reforestation and Beyond

With our planet at a precipice, the preservation and expansion of forests are thrust into the global spotlight. As nations grapple with the inadequacy of emission reductions, reforestation emerges as a beacon of hope. The idea is simple yet profound: by nurturing existing forests and strategically planting new trees, we amplify nature's ability to counteract our carbon emissions.

However, this endeavor poses multifaceted challenges. Land ownership, equitable distribution of benefits, and the true cost of preserving these ecosystems become focal points. It is imperative that the noble cause of reforestation does not inadvertently perpetuate social or economic inequities.

In a world where climate solutions are paramount, the significance of land and forests as allies cannot be overstated. They stand as testament to nature's resilience and offer tangible pathways to confront climate change head-on. As we navigate the path to a sustainable future, the role of land and forests serves as a compelling reminder of the interconnectedness that binds humanity to the environment.

It all started in the 90s when international conferences took up a crucial issue of sustainable development. Decades after discussing climate-related challenges, now governments, people and corporations are actually assessing and contributing to the sustainability journey of the planet. The target set to lower the global temperatures is one such step. Such initiatives have turned people’s heads towards ever-pressing issues of global warming and associated challenges.

Here, often we are stormed with a sea of information that we focus majorly on the context rather than the significance of terms on an individual basis. Sustainability, climate change, net-zero, carbon emissions are the buzzwords. The context remains the same as that of climate change but fundamentally they are different. Everyone, including companies, tend to understand the climate lingo but hardly they are clear about the goals. Read on further and know the difference among the concepts of carbon-neutral, net-zero and climate positive.

Carbon neutral:

As the name suggests, carbon-neutral is the balancing out of carbon emissions from your firm. It is more like owning a complete responsibility for one’s own carbon emissions. Corporates and companies need to assess and analyse their carbon emissions. Such analysis gives an idea about the number of carbon emissions that need to be balanced out. It is then that firms plan to come out carbon neutral by saving an equivalent amount of carbon emissions somewhere else in the world.

Net-zero:

The Net-zero concept is a simple concept of balancing out the net emissions created. Here emissions are of greenhouse gases, particularly carbon dioxide. These levels are reached when anthropogenic emissions balance out with the help of pre-determined activities.

Climate Positive:

It lies in that much-awaited stage in the sustainability journey, wherein companies or entities tend to remove an additional amount of carbon from the atmosphere. It has reached the level of achieving net-zero emissions and now stands beyond the same. This term is often used interchangeably with climate negative.

Is your company carbon neutral or climate positive or has net-zero emissions?

Well, after knowing these are different and important concepts, a firm needs to introspect about these. Raising these questions can help us achieve our environmental goals faster. Prior to that, your company needs to analyse emissions. Accordingly, you can set realistic goals and plan a roadmap. For the same, consult a team of professionals dealing in the same.

Hopefully, tech giants and corporates are taking steps towards assessing their goals and contributions. However, a lot needs to be done collectively on this pressing issue, until we balance out our needs with our climate’s needs.

The tropics, a region encircling the Earth's equator, have long been perceived as lush rainforests with exotic animals and unchanging weather. However, they are also often associated with poverty, unstable governments, and environmental destruction. A new report, "The State of the Tropics," provides a deeper and more nuanced understanding of this diverse region.

Changing Perceptions

Historically, the tropics were misunderstood, with Aristotle even claiming that no civilization could thrive there. The report calls for a shift in perspective, urging recognition of the tropics from within and embracing local wisdom and experience. Compiled by 12 institutions, this comprehensive 400-page report delves into demographics, health, science, economics, biodiversity, and climate change..

Population Growth

Currently, the tropics are home to 40% of the world's population and 55% of children under five. Population growth is particularly rapid in Africa. By 2050, over half of the global population and 67% of young children will reside in the tropics. The region is expected to add 3 billion people by the end of the century, necessitating a rethinking of global priorities in aid, development, research, and education.

Economic and Social Challenges

A booming population drives increased demand for food, water, and resources. Tropical economies are growing 20% faster than those in temperate regions but still house two-thirds of the world's extreme poverty. While extreme poverty has decreased in Southeast Asia and Central America, it has doubled in Central and Southern Africa since the 1980s. Despite these challenges, there have been improvements, including a decline in undernourishment, rising life expectancy, and reduced maternal and child mortality.

Health Issues

The tropics face unique health challenges, with diseases like dengue fever and malaria remaining significant threats. These diseases are rarely found in temperate regions but are major health concerns in tropical countries.

Land and Environmental Struggles

Growing populations and consumption have led to land-use clashes. Indigenous groups struggle to maintain control over their lands as corporations seek resources for agriculture, livestock, and commodities. Conservationists are working to preserve vital ecosystems, as the tropics host 80% of Earth's terrestrial biodiversity and 95% of mangrove and coral reef biodiversity. Unfortunately, forest loss continues, especially in Oceania.

Oceanic Pressures

Marine resources in the tropics, including coral reefs and mangroves, face unprecedented pressures. Overfishing and destructive practices have depleted species. Mangroves, crucial for coastal protection and carbon storage, are being rapidly destroyed for aquaculture and development. Climate change and ocean acidification further threaten these ecosystems.

Future Challenges

Climate change poses significant challenges for the tropics, including extreme weather, rising seas, and changing precipitation patterns. These changes could impact agriculture and increase the number of refugees and regional conflicts. The tropics are expanding into temperate zones, which will have implications for water resource management and agricultural systems.

Conclusion

The future of the tropics is one of rising influence and wealth, alongside ongoing struggles with poverty, hunger, health standards, biodiversity, climate change, and resource conservation. The report emphasizes the importance of sustainable development and conservation to safeguard resources for future generations. The tropics hold great potential and influence, making it crucial to address these challenges thoughtfully and effectively.
