Protecting Life on Land for a Sustainable Future
Imagine a world where the air we breathe is polluted, the water we drink is contaminated, and the delicate balance of nature is on the verge of collapse. Our planet's ecosystems, with their remarkable biodiversity, provide essential services that sustain life and bolster our resilience against mounting challenges. Yet, the actions of humankind have drastically altered the face of these terrestrial ecosystems, leading us down a perilous path with alarming consequences.
The evidence of our impact on ecosystems is undeniable. Shockingly, approximately 40,000 species teeter on the brink of extinction within the coming decades. This staggering number vividly illustrates the magnitude of the threat posed to the intricate web of life surrounding us. The destruction of our forests is a prime example of this crisis, as an area equivalent to the size of Iceland—10 million hectares—is lost each year. The consequences of rampant deforestation reverberate throughout the natural world, resulting in the loss of critical habitats for countless species and the disruption of vital ecosystem functions.
In 2015, the international community acknowledged the urgent need to address the global triple planetary crisis of climate change, pollution, and biodiversity loss. As part of the United Nations Global Goals, Sustainable Development Goal 15 was established with a specific focus on protecting, restoring, and promoting the sustainable use of terrestrial ecosystems. This goal acknowledges the crucial importance of preserving biodiversity, combating land degradation, and ensuring the sustainable management of forests.
We need to understand the implications of biodiversity loss. Preserving biodiversity and maintaining healthy ecosystems not only support the survival of countless plant and animal species but also directly benefit human well-being. Achieving SDG 15 has the potential to enhance food security, promote sustainable livelihoods, and increase resilience to climate change. Furthermore, it offers opportunities for eco-tourism, nature-based solutions, and the sustainable use of natural resources. In summary, SDG 15 plays a vital role in achieving sustainable development by safeguarding life on land and fostering harmony between human activities and the environment.
Key Targets and Indicators:
SDG 15 encompasses a set of specific targets and indicators that help measure progress and guide efforts toward its achievement. These targets include halting deforestation, restoring degraded land, conserving biodiversity, and combating desertification. Indicators such as forest cover, protected areas, species extinction rates, and land degradation provide a roadmap for tracking progress and identifying areas that require intervention.
Why it Matters
The degradation of land is posing a significant threat to the quality of life for approximately 3.2 billion individuals, exacerbating climate change, and pushing numerous species towards extinction. Our planet's land area is comprised of forests, which encompass nearly 31 percent of its total expanse. These forests play a crucial role in sustaining our existence, providing us with clean air to breathe, fresh water to drink, and nourishing food to eat. They serve as habitats for over 80 percent of terrestrial species, encompassing a diverse array of animals, plants, and insects. Unfortunately, the current era is witnessing an unprecedented acceleration in the decline of biodiversity, presenting potential consequences that are cause for concern.
Biodiversity Loss: Forests are home to a diverse range of plant and animal species. When forests are lost, numerous species lose their habitats, leading to a decline in biodiversity and the potential extinction of certain species.
Carbon Emissions: Forests store vast amounts of carbon dioxide, a greenhouse gas that contributes to climate change. When forests are cleared or burned, the stored carbon is released into the atmosphere, exacerbating global warming.
Climate Regulation: Forests play a crucial role in regulating local and global climates. They influence rainfall patterns, maintain moisture levels, and help stabilize temperatures. Forest loss can disrupt these climate-regulating functions.
Social and Economic Impacts
Displacement of Indigenous Communities: Many indigenous communities rely on forests for their livelihoods, cultural practices, and identity. Forest loss can lead to the displacement and marginalization of these communities.
Loss of Ecosystem Services: Forests provide a wide range of ecosystem services, including water purification, soil conservation, and flood control. When forests are lost, these services are compromised, affecting communities that depend on them.
Economic Consequences: Forests contribute to the economy through timber production, non-timber forest products, ecotourism, and other forest-related industries. Forest loss can result in economic losses and reduced opportunities for sustainable economic development.
To develop effective strategies and policies for safeguarding, restoring, and promoting the sustainable use of terrestrial ecosystems, managing forests sustainably, combating desertification, halting and reversing land degradation, and addressing biodiversity loss, it is crucial to have a comprehensive understanding of the significant developments and challenges in this area. A recent report by the United Nations on Sustainable Development Goal 15 provides a snapshot of the goal, shedding light on the current state of affairs. By examining the following fact, we can gain insights into the progress made and the setbacks encountered about SDG 15.
SDG 15 Factsheet
Forest Cover Loss: The global forest cover decreased from 31.9% of the total land area in 2000 to 31.2% in 2020, resulting in a net loss of approximately 100 million hectares.
Deforestation Drivers: Agricultural expansion is the leading cause of deforestation, accounting for nearly 90% of global deforestation. This includes 49.6% for cropland expansion and 38.5% for livestock grazing.
Forest Certification: Between 2010 and 2021, the area of forest land under certification schemes witnessed a 35% increase. The proportion of forests under long-term management plans also rose from 54% in 2010 to 58% in 2020.
Protected Areas: In 2020, more than 700 million hectares of forest (18% of global forest cover) were legally designated as protected areas, offering crucial conservation measures.
Habitat Encroachment: Human activities such as logging and farming are encroaching upon habitats, endangering approximately 20% of reptile species.
Biodiversity Coverage: The mean percentage coverage of key biodiversity areas globally increased from over one quarter in 2000 to nearly one-half in 2021, highlighting efforts to protect critical habitats.
National Targets: An increasing number of countries are setting national targets to incorporate ecosystem and biodiversity values into their accounting and reporting systems. As of January 2022, 37% of assessed countries are on track to achieve or surpass their national targets.
A Look at Challenges and Way Forward.
The importance of healthy natural ecosystems cannot be overstated, as they form the foundation for many business activities and the well-being of communities. Taking care of these ecosystems can yield immense benefits. However, achieving the objectives of SDG 15, which focuses on life on land, is confronted by significant challenges. Deforestation, habitat loss, and land degradation pose major threats to biodiversity and ecosystems.
