Ecosystem Management and Conservation

Ecosystem management and conservation have become increasingly important in recent years, as concerns about the state of our environment and natural resources continue to grow. The main goal of ecosystem management is to effectively maintain and ethically utilize natural resources while considering the social, economic, political, and cultural needs of both present and future generations.

Ecosystem management is a comprehensive and integrated approach that calls for a significant shift in the way we perceive and interact with natural and human environments. Numerous organizations and individuals have offered various definitions of ecosystem management, but two key themes emerge across most of these explanations:

• Ecosystem management should focus on preserving or enhancing the health and functioning of ecosystems.
• Ecosystems should provide a diverse range of goods and services to meet the needs of current and future generations.

In essence, ecosystem management aims to balance the conservation of ecological systems and resources with the needs and desires of human populations. This involves incorporating scientific knowledge of ecological relationships and processes into decision-making, while also taking into account complex social, political, and value-related factors. By adopting an adaptive and holistic approach to resource management, we can work towards preserving the integrity of our ecosystems for the long term.

Components of Ecosystem Management are:
Ecosystem Management involves several key components that help maintain and protect the biodiversity and ecological integrity of our environment. These components include:

• Recognizing the interconnectedness of various aspects of biodiversity, such as genes, species, populations, ecosystems, and landscapes. This allows for a more comprehensive understanding of the environment and its complex relationships.
• Incorporating appropriate spatial scales to encompass relevant ecological processes, while also focusing on ecological boundaries rather than administrative ones. This ensures that the management considers the actual environmental needs rather than being constrained by political borders.
• Acknowledging the role of human society as part of the ecosystem and considering the current needs for maintaining a healthy environment to meet future demands. This involves finding a balance between human development and environmental protection.
• Mimicking natural disturbance patterns to help maintain biodiversity. This can involve methods such as controlled burns or other techniques that replicate the effects of natural disturbances on ecosystems.
• Ensuring the ecological integrity of the environment by protecting viable populations, patterns, and processes of all native species. This involves the conservation of habitats and the promotion of diverse and healthy ecosystems.
• Taking into account appropriate time scales and adopting long-term planning for ecosystem management. This allows for more effective and sustainable management practices that account for the natural cycles and processes of ecosystems.
• Implementing management experiments that include a well-designed experimental plan, along with adequate monitoring and documentation of the effects of these management practices. This helps to promote learning and improvement in ecosystem management techniques.
• Encouraging interagency coordination and communication with society to ensure that ecosystem management plans are effectively implemented and understood by all stakeholders. This promotes greater collaboration and public involvement in the management of our environment.

Ecosystem management involves preserving and protecting wildlife and natural habitats from human modification and depletion. Nature reserves, wildlife refuges, and similar controlled areas have been created worldwide to protect habitats and their communities. However, it is essential to understand that ecosystems are dynamic and that humans play a significant role in their existence.

The second aspect of ecosystem management focuses on maintaining a sustained yield from organic resources, such as breeding stocks of marine animals and forestry practices. Soil conservation, which aims to sustain agricultural fertility, also falls under this category. Some argue that this is the most critical aspect of ecosystem maintenance, especially considering the growing pressure on food resources.

There is a need for a fundamental shift in how ecosystems are valued and managed due to the threats posed by climate change and unsustainable demands for ecosystem services. Current economic models and political decision-making processes undervalue ecosystems. The authors propose four strategies to prioritize ecosystem protection and argue that the conservation and sustainable management of ecosystems should be at the heart of decision-making. Ultimately, it is crucial to protect vital ecosystem services that we all depend on.

Defining the problem
The problem of increasing greenhouse gas emissions is twofold: human activities are causing emissions to rise, while the global capacity to absorb them is decreasing due to ecosystem degradation. This imbalance leads to climate instability and a reduction in essential ecosystem services, such as clean air, food, and water security.

• By appropriately valuing, protecting, and managing the world's ecosystems, we can achieve two crucial objectives: cost-effective climate stabilization through natural carbon sequestration processes, and securing the delivery of vital ecosystem services.
• To stabilize the climate, we must balance emission sources (both human and natural) with the global ecosystems' ability to act as a carbon sink. By protecting and managing the world's ecosystems, we can enhance their capacity to absorb carbon and secure essential life-supporting ecosystem services, which in turn will help society adapt to climate change.
• Even without human activities, carbon would still flow through the atmosphere due to natural biological and geological processes. Our planet is a dynamic system that produces and absorbs carbon and other greenhouse gases through various natural cycles and ecosystems, resulting in past climate patterns influenced by factors such as the Milankovitch Cycles and solar activity.
• Human activities have disrupted these natural carbon cycles in two main ways: by creating significant new sources of carbon emissions through the use of fossil fuels, and by degrading natural carbon sinks by polluting or transforming ecosystems. The combination of these human interventions has altered the planetary balance between carbon sources, sinks, and storage pools, resulting in the Earth emitting more carbon than it can absorb. This growing imbalance is evident in the increasing CO2 concentrations in the atmosphere, which contribute to climate change.

In summary, there are three main components to the global carbon cycle:

• Emissions from human activities
• Emissions from ecosystems
• The single guaranteed sink: the capacity of global ecosystems to absorb carbon

By understanding and addressing these components, we can work towards a more sustainable balance between emissions and the planet's ability to absorb them.

The crucial point to understand here is that global and regional ecosystems play a significant role in regulating the climate, both by releasing greenhouse gases (sources) and capturing them (sinks), as well as through other direct and indirect climate interactions.

• Currently, ecosystems absorb approximately half of the CO₂ emissions generated by human activities, with oceans taking in about 24% and land around 30%. The remaining portion is added to the atmospheric pool. However, the ability of ecosystems to absorb CO₂ is decreasing by about 1% per decade and is expected to decline more rapidly due to climate change and human impacts. At the same time, emissions from human activities are increasing: it is estimated that annual global CO₂ emissions from human activities are around 10 gigatons, with about 1.5 Gt coming from land-use changes (primarily deforestation).
• The net result is a growing imbalance between emissions and the capacity to absorb them. To stabilize the climate, it is necessary to manage all three components of the global carbon cycle, not just those related to fossil fuels and other human activities. The main issue is that the post-2012 negotiations focus primarily on one component of the three-way balance, specifically human-generated emissions. The danger of this approach is that regulating human-based emissions alone may not be enough to achieve climate stabilization.

Climate stabilisation: the need for balance

Climate stabilization is a critical issue that requires a balanced approach to effectively address the problem. A simplified representation of the global climate stabilization challenge can be described as a three-way balance:

• Climate stability = Global ecosystems' capacity to absorb greenhouse gases (GHGs) - (natural emissions from ecosystems + human-induced emissions)
• The evolution of this balance will largely determine the rate and magnitude of human-induced climate change and the necessary mitigation efforts to stabilize CO₂ (and other GHG) concentrations at any given level. Currently, the balance is skewed towards climate instability.
• There is a dangerous paradox at play: if human-induced emissions continue to increase, emissions from ecosystems are also likely to rise due to positive feedback mechanisms, while the capacity of ecosystems to absorb emissions decreases. This imbalance carries significant risks of irreversible climate destabilization. As evident in the figure, ecosystems play a role in two of the three components of the stabilization balance.

Focusing solely on human-based emissions and not fully recognizing the role ecosystems play in climate regulation risks addressing only one aspect of the three-way balance. To achieve climate stabilization (or resilience), there is a need to balance the three components in ways that:

• Maximize the global ecosystem capacity to absorb GHGs,
• Minimize emissions from ecosystems (or at least be able to quantify them and understand the underlying processes), and crucially,
• Reduce emissions due to human activity.

Ecosystems, therefore, play a vital and increasingly important role in both ecosystem-based mitigation (carbon sequestration and storage) and ecosystem-based adaptation (i.e., the foundation for societal adaptation to climate change impacts).

Ecosystems: the “˜Win-Win-Win’ link between mitigation, adaptation and sustainability
An ecosystem-based approach can achieve both climate change mitigation and adaptation goals while also serving as the foundation for long-term sustainability. Protecting ecosystems offers numerous benefits, both directly through the sustainable management of biological resources and indirectly through the safeguarding of ecosystem services.

• From a social perspective, this approach can provide secure livelihoods, especially for the poor, public health benefits, cultural and aesthetic values, and community support. Economically, resilient ecosystems ensure the provision of services that support all types of economic activity. In terms of climate regulation, ecosystems can function as tools for mitigation by reducing natural sources of emissions or increasing absorption capacity through appropriate management. Environmentally, resilient and healthy ecosystems can support long-term sustainability.
• These combined benefits offer multiple cost-effective advantages and opportunities to human societies, including economic, cultural, health, and many more. Additionally, a fourth 'win' can be achieved by generating profitable outcomes through the utilization of healthy ecosystems' benefits. It is crucial to highlight that these solutions are achievable. Some are relatively simple and can be implemented immediately at a low cost, while others may require careful planning, development, and more significant investments.

Ecosystems as a ‘safety net’

• Ecosystems can act as a safety net against potential failures in reducing emissions from human activities. Adopting an ecosystem management approach at a global scale should not be seen as a substitute for reducing human emissions, but rather as a complementary strategy for both mitigation and adaptation. Although it is crucial to agree on emissions reduction, there is no guarantee that the targets set will be adequate for climate stabilization or achieved. Therefore, under the precautionary principle, ecosystems should be protected and promoted as the primary mechanism for climate regulation and the basis for supporting an adapting human society.
• However, traditional approaches to addressing economic and environmental issues, such as cost-benefit analysis and risk assessments, may not effectively deal with the uncertainty in ecosystem responses to climate change and the additional pressures from a rapidly growing society. Since the resilience capabilities of ecosystems cannot be accurately defined, the security provided by them acting as a safety net is uncertain.
• As a result, there is a need for a significantly greater effort to ensure the health of ecosystems and avoid exceeding their tolerance limits. This requires a deeper scientific understanding of biodiversity and ecosystem processes to identify their vulnerability and the risk of exceeding resilience. Additionally, there is a need to monitor the health of ecosystems to better recognize emerging threats.

People in the balance

• There is a crucial need to find a balance between various competing demands and trade-offs within socio-ecological systems. As the human population continues to grow, so does the expectation for improved living standards and material possessions, resulting in increased resource consumption. To achieve a balanced system, it is necessary to shift human expectations, aspirations, and behaviors, as well as manage resource use.
• It is important to recognize that poverty alleviation is a primary objective and the aspirations of less fortunate individuals should be respected and supported. On the other hand, excessive resource consumption must be reduced to achieve sustainable levels of equity and environmental preservation. Ecosystems provide essential resources for livelihood, especially for those in poverty, while excessive resource demands from wealthier individuals contribute to ecosystem degradation.
• One of the keys to implementing effective solutions lies in behavioral change. People are more likely to adopt new practices if there are economic benefits and a clear rationale for change. Thus, creating a balanced system requires the development of new economic structures, societal ethics, and a sense of shared responsibility, all of which should be supported by investments in education.

The Economics of Ecosystems

• The Economics of Ecosystems and Biodiversity final report, presented at the Convention on Biological Diversity 10th Conference of the Parties meeting in Nagoya, Japan, signifies a shift in the way ecosystems are valued and utilized. The report outlines the need for valuation and the methods to achieve it. The challenge lies in incorporating these approaches into mainstream economics. A crucial question remains: how long will it take for these approaches to become mainstream and effectively halt the decline in ecosystem health amid climate change uncertainties and ecosystem resilience? A determining factor will be the resistance from existing economic thinking and vested interests in current economic models.
• This article emphasizes the importance of placing ecosystem protection and valuation at the core of economic and political decision-making. To promote the adoption of these goals, it is essential to foster a society-wide understanding and appreciation of the significance of biodiversity and ecosystems in providing the vital 'life support systems' we rely on. Once this is achieved, new policies and economic models will be easier to develop and implement. Providing evidence of the economic benefits of ecosystems is a crucial step in this process, but it may not be enough on its own. Without the fundamental acceptance of the vital role biodiversity and ecosystems play by all sections of society, there is a risk that market-driven mechanisms aimed at protecting them will only partially succeed, and past market failures that resulted in ecosystem degradation may be repeated.
• Engaging with politicians and business leaders is crucial to strike a balance between ecosystem protection and the continued use of natural capital. This also includes integrated moves towards low carbon economies, such as the Green Economy Initiative. To provide a secure foundation for the transformational change needed for sustainable resource use, it is essential to apply the precautionary principle and establish a predetermined level of conservation and protection for ecosystems that economic activity cannot degrade. This would maintain a fundamental level of ecosystem health and resilience in the face of market failures and uncertainties in climate change impacts.

Four complementary strategies
Four essential strategies can be employed to address climate change and sustainability through ecosystem management and protection:

• Political commitment: Elevate the importance of ecosystems in climate change and sustainability policies at local, national, and international levels to create a sense of urgency.
• Investment: Incorporate investments in ecosystem management and protection into global climate change funding. Ensure that the scale of investment is proportionate to the value of ecosystem services provided.
• Incentives: Implement incentives to reduce emissions, alleviate pressures on ecosystems, and support changes that enhance environmental resilience and resource sustainability. This includes incentives for increased land and water protection.
• Information: Establish comprehensive information networks and strengthen connections between ecosystem management, climate change adaptation, and disaster risk reduction communities, as well as between science, economics, politics, and policy. Encourage information sharing between countries, including North-South and South-South exchanges. Expand and support long-term monitoring of critical environmental variables and processes related to ecosystem-based climate change mitigation and adaptation.

Policy recommendations for decision-makers include:

• Integrate ecosystem-based adaptation into climate change policies at international, national, and regional levels.
• Acknowledge the vital role of healthy ecosystems in climate change mitigation, adaptation, and long-term sustainability.
• Include emissions from ecosystems and their stored greenhouse gas stocks in the United Nations Framework Convention on Climate Change (UNFCCC) reporting sectors.
• Protect and preserve existing carbon stocks in ecosystems, such as soils and vegetation, to prevent further emissions.
• Enhance ecosystem carbon sink potential and reduce deforestation.
• Recognize the global public good provided by ecosystem interactions and services that cross national boundaries.
• Align climate change policies with other relevant conventions, such as those related to habitat, water, and biodiversity.
• Integrate ecosystem-based mitigation into Nationally Appropriate Mitigation Actions (NAMAs) and ecosystem-based adaptation into National Adaptation Plans of Action (NAPAs).
• Support funding for national and local projects that strengthen ecosystem resilience and build adaptation capacity in human systems.
• Improve education, training, and communication capabilities.
• Promote strategies that emphasize protected areas and integrated sustainable resource use from ecosystems.
• Support research on climate-ecosystem interactions, ecosystem processes and functions, the complex relationships between society and ecosystems, and the development of climate models that include ecosystem feedbacks.

Conclusion

In conclusion, ecosystem management and conservation are critical components in addressing climate change and ensuring the long-term sustainability of our environment. By focusing on preserving ecosystems, we can achieve a balance between human development and environmental protection. This involves adopting adaptive and holistic approaches to resource management, incorporating scientific knowledge, and considering various social, political, and economic factors. To effectively tackle climate change and maintain our planet's health, we must prioritize ecosystem protection, invest in ecosystem management, implement incentives for sustainable resource use, and strengthen information sharing and collaboration among various stakeholders.
