The widespread concern over the status of ecosystems is the product of a movement gathering momentum over the last hundred years. Conservation has evolved from the narrow goal of protecting wildlife in reserves to a far broader imperative — the management of Earth’s entire ecological support system in the face of climate change, population growth, and unsustainable resource demands.

Definition of ecosystem management

Ecosystem management is a process that aims to conserve major ecological services and restore natural resources while meeting the socio-economic, political, cultural, and needs of current and future generations (Mumba, Munang and Rivington, UNEP).

The principal objective is the efficient maintenance and ethical use of natural resources. It is a multifaceted and holistic approach that requires a significant change in how the natural and human environments are identified, valued, and managed.

Two themes run through virtually every definition of ecosystem management: (1) management should maintain or improve ecosystems, and (2) ecosystems should provide a range of goods and services to current and future generations. These twin commitments — ecological integrity and sustained human benefit — define the entire field.

The key insight that is often overlooked in environmental management is that ecosystems cannot simply be “preserved” — they are dynamic in character, constantly changing through succession, disturbance, and adaptation. Equally important, humans are an important habitat factor in many ecosystems; the ecological niche occupied by human communities cannot suddenly be left vacant when reserves are established. The classic failure of early East African National Parks — where excluding traditional hunters caused elephant and hippo populations to increase until they devastated their own habitat — illustrates this principle with painful clarity.

Evolving Definitions of Ecosystem Management

Multiple organisations and scholars have offered definitions, each emphasising different aspects. Together, they reveal how the concept has matured from a narrowly technical concern to a holistic socio-ecological governance framework.

“Regulating internal ecosystem structure and function, plus inputs and outputs, to achieve socially desirable conditions.”

Agee and Johnson, 1987 — earliest modern framing; emphasises regulation and social goals

“A strategy or plan to manage ecosystems for all associated organisms, as opposed to a strategy or plan for managing individual species.”

Forest Ecosystem Management Assessment Team, 1993 — key departure from single-species conservation

“A resource management system designed to maintain or enhance ecosystem health and productivity while producing essential commodities and other values to meet human needs and desires within the limits of socially, biologically and economically acceptable risk.”

American Forest Paper Association, 1993 — integrates risk assessment with human needs

“Integrating scientific knowledge of ecological relationships within a complex socio-political and values framework toward the general goal of protecting native ecosystem integrity over the long term.”

Grumbine, 1994 — explicitly embeds science within politics and values

“Management is driven by explicit goals, executed by policies, protocols, and practices, and made adaptable by monitoring and research based on our best understanding of the ecological interactions and processes necessary to sustain ecosystem structure and function.”

Christensen et al., 1996 — the most operationally complete definition; emphasises adaptive management

Core Global Initiatives

Global initiatives provide the overarching frameworks, funding, and targets necessary to mobilise international action for ecosystem restoration. Without global coordination, national efforts remain fragmented and insufficient to address planetary-scale ecological challenges.

UN Decade on Ecosystem Restoration (2021–2030)

• Co-led by UNEP and FAO, the UN Decade on Ecosystem Restoration is the most ambitious global ecological initiative in history. Its mandate is to prevent, halt, and reverse the degradation of ecosystems worldwide — on land, in freshwater systems, and in the ocean.
  • Target: restore billions of hectares of degraded land and ocean ecosystems.
  • Directly boosts biodiversity, enhances food security, and builds climate resilience.
  • Serves as the operational programme implementing SDG 15 (Life on Land), SDG 14 (Life Below Water), and the land degradation neutrality target under UNCCD.
  • Aligned with the Kunming-Montreal GBF’s “30×30” protected areas target and the “30by30” restoration target.

Global Environment Facility (GEF)

• The GEF is the primary multilateral funding mechanism for global environmental management.
• UNEP utilises GEF grants and co-financing to support countries in tackling severe environmental challenges, promoting integrated land and water management practices that actively protect and enhance vital ecosystem services.
• The GEF-8 replenishment (2022–2026) committed $5.33 billion — the largest in its history — for biodiversity, climate change, land degradation, international waters, chemicals, and forests.

Strategic Ecosystem-Based Approaches

Ecosystem management relies most fundamentally on ecosystem-based approaches — strategies that use nature’s own processes rather than engineering solutions to manage resources equitably and sustainably.

Ecosystem-based Adaptation (EbA)

• EbA uses biodiversity and ecosystem services as part of an overall adaptation strategy to help people and societies adapt to the negative impacts of climate change. Rather than relying solely on engineered grey infrastructure (sea walls, pipes, reservoirs), EbA deploys healthy ecosystems as natural infrastructure that provides adaptation benefits at lower cost and with positive ecological co-benefits.
  • EbA efforts focus on integrating ecosystem conservation directly into national development and adaptation plans.
  • Recommended to policy-makers: “Ensure ecosystem-based adaptation is an integral component of climate change policy at international, national and regional scales” (Mumba, Munang and Rivington, UNEP).
  • EbA should be incorporated into National Adaptation Plans of Action (NAPAs) and Nationally Appropriate Mitigation Actions (NAMAs).

Integrated Water Resources Management (IWRM)

• IWRM is a process that promotes the coordinated development and management of water, land, and related resources to maximise economic and social welfare without compromising ecosystem sustainability. It is the dominant paradigm in global water governance, replacing the older sectoral approach where irrigation, drinking water, industrial water, and river conservation were managed by separate agencies with conflicting mandates.
  • Treats watersheds as the fundamental unit of water management — matching ecological boundaries rather than administrative ones.
  • Requires genuine stakeholder participation, including local communities, farmers, industries, and downstream users.
  • Integrates environmental flows — the minimum water flows needed to sustain river ecosystem health — into water allocation decisions.
  • India’s National Water Policy (2012) adopted IWRM principles, recognising the river basin as the unit of planning and mandating environmental flows for all rivers.

Marine spatial planning and coastal management

• Marine Spatial Planning (MSP) is a coordinated management system designed to analyse and allocate the spatial and temporal distribution of human activities in marine and coastal areas to achieve ecological, economic, and social objectives.
• It is the marine equivalent of terrestrial land-use planning — creating designated zones for conservation, fisheries, shipping, aquaculture, tourism, and energy production within a single integrated framework.

Targeted Regional Ecosystem Management

Ecosystem management efforts are tailored to the unique ecological, social, and economic characteristics of different ecosystem types. Each major ecosystem type faces distinct pressures and requires specific management approaches.

Ecosystems and the Global Carbon Cycle — A Three-Way Balance

One of the most critical insights in modern ecosystem management science is that climate stabilisation cannot be achieved solely by reducing fossil fuel emissions — it requires the active management of the global carbon cycle through ecosystem protection and restoration. Mumba, Munang and Rivington (UNEP) articulate this as a three-component balance:

The dangerous paradox is that if emissions from human activity increase, emissions from ecosystems are likely to increase as well due to positive feedback mechanisms — permafrost thaw releasing methane, drought-killed forests releasing carbon, coral reef death eliminating marine carbon uptake — while the capacity of ecosystems to absorb emissions simultaneously decreases. Current policy is too focused on human-based emissions alone. Regulating these will be insufficient to achieve climate stabilisation without also managing ecosystem sink capacity.

Human activity has intervened in natural carbon cycles in two main ways: by creating major new sources of carbon from fossil fuel use, and by degrading natural carbon sinks through deforestation, wetland drainage, soil degradation, and ocean acidification. The net effect is an Earth emitting more carbon than it can absorb — and ecosystem management is the only available mechanism to re-balance the sink side of the equation.

Ecosystems as the “Win-Win-Win” Link

An ecosystem approach can simultaneously fulfil objectives for mitigation of, and adaptation to, climate change, while also forming the foundation for long-term sustainability. This triple benefit — described by Mumba, Munang and Rivington (UNEP) as the “win-win-win” link between mitigation, adaptation, and sustainability — is what makes ecosystem management qualitatively different from other environmental interventions.

The fourth win — profitable outcomes from utilising healthy ecosystems — is increasingly recognised through payment for ecosystem services (PES) schemes, REDD+ carbon finance, sustainable fisheries certification, and eco-tourism revenue. These mechanisms convert the economic value of ecosystem services into direct financial incentives for conservation, aligning market forces with ecological sustainability.

Ecosystems as a safety net

The adoption of an ecosystem management approach at global scale serves as a “safety net” against possible failures in efforts to reduce emissions from human activity. There is no absolute guarantee that emissions reduction targets will be either correct for climate stabilisation or met. Using the precautionary principle, ecosystems must be protected and promoted as the primary mechanism for climate regulation and as the foundation for supporting an adapting human society — not as an alternative to emissions reduction, but as an essential complementary strategy.

People in the balance

There is a need to balance many opposing demands within socio-ecological systems. A fundamental tension exists: the aspirations of the poor — for whom ecosystems provide essential livelihoods — must be respected and supported, while excessive resource consumption by the wealthy causes ecosystem degradation that ultimately harms the poor most severely.

The key to practical solutions lies in behavioural change, which happens when: (a) there is an economic benefit, and (b) there is a clear rationale as to why change is needed. New economic systems, societal ethics, and an ethos of collective responsibility — supported by investment in education — are therefore essential preconditions for effective ecosystem management.

Four Complementary Strategies for Ecosystem Protection

Mumba, Munang and Rivington (UNEP) propose four mutually reinforcing strategies for prioritising ecosystem protection in the face of climate change — a framework that applies equally to national and international governance.

• Political commitment
  • A sense of urgency to raise the profile of ecosystems in climate change and sustainability policy at local, national, and international levels. Without political will, no technical solution can be implemented at the required scale or speed.
• Investment
  • Explicit inclusion of ecosystem management in Global Climate Change Funds, development finance, and national budgets. The scale of investment must be commensurate with the quantified value of ecosystem services — currently massively undervalued in economic models.
• Incentives
  • Deliberate focus on introducing incentives to reduce emissions, ease pressures on ecosystems, and support increased environmental resilience. Includes carbon pricing, PES, REDD+ finance, and incentives for land and water protection.
• Information
  • Comprehensive monitoring of environmental variables; closer links between ecosystem management, climate adaptation, and disaster risk reduction. North-South and South-South information sharing. Expanded long-term ecosystem monitoring networks.

Transboundary Cooperation — Managing Ecosystems Across Borders

Because nature does not recognise political borders, transboundary cooperation is not an optional addition to ecosystem management — it is a structural necessity. Migratory species, shared river systems, contiguous forests, and atmospheric processes all operate across national jurisdictions. A unified international framework allows nations to implement major multilateral environmental agreements more effectively than any country could manage alone.

Key multilateral frameworks enabled by transboundary cooperation

Convention on Biological Diversity (CBD)

• Conservation of biodiversity, sustainable use, and equitable benefit sharing. 196 parties. Implementation requires cross-border species management and habitat connectivity.

Paris Agreement (UNFCCC)

• NDCs, carbon markets, and climate finance all require international coordination. Ecosystem-based mitigation (REDD+) is intrinsically transboundary — forests store carbon globally regardless of where they stand.

Ramsar Convention on Wetlands

• Internationally important wetlands designated as Ramsar sites. Migratory waterfowl and fish connect Ramsar sites across national boundaries — making transboundary coordination essential for wetland health.

UNCCD — Desertification

• Combat desertification in affected countries through National Action Programmes. Transboundary dust storms, shared dryland river systems, and cross-border pastoral routes require cooperative management.

Transboundary protected areas and peace parks

Transboundary Protected Areas (TBPAs) — also called “peace parks” — are among the most powerful instruments in ecosystem management, combining political reconciliation with ecological connectivity. Notable examples include the Greater Limpopo Transfrontier Park (South Africa, Mozambique, Zimbabwe), the Kavango-Zambezi TFCA (five southern African nations), and the Alps-Adriatic transboundary management area in Europe.

India’s Ecosystem Management Efforts — Synthesis

The economics of ecosystems — valuation challenge

The publication of The Economics of Ecosystems and Biodiversity (TEEB) final report at CBD COP 10 in Nagoya (2010) marked a turning point in how ecosystems can be valued and managed. TEEB set out the basis for ecosystem service valuation and methods for incorporating it into mainstream economics. The challenge — still largely unresolved — is making these approaches part of mainstream economic decision-making fast enough to halt the decline in ecosystem health. Resistance from entrenched economic thinking and vested interests in current economic models remains the dominant obstacle.

For India, ecosystem services valuation studies have revealed extraordinary values: the Sundarbans mangroves provide storm protection services worth ₹10,000–15,000 crore annually; India’s wetlands support fisheries worth over ₹8,000 crore per year; the Himalayan glaciers underpin agriculture, drinking water, and hydropower for over 500 million people — a value that no market currently prices. Including these values in national accounting (Green GDP or Genuine Progress Indicator) would radically shift the cost-benefit calculus of development decisions.
