Key Ideas and Applications for Ecosystem Services
SUMMARY
The importance of natural ecosystems and their role in enhancing human welfare and quality of life have drawn
increasing attention from the general public. The existence, well-being, and prosperity of humans are dependent upon
ecosystem services and their continuous provision.
In order to make decisions about natural resource management that will benefit landowners and society as a whole,
governments, communities, and natural resource managers are adopting a more comprehensive ecosystem approach.
Because it is the direct source of certain services, like food and fiber, and because it supports other services, like clean
water and air, through the participation of organisms in energy and material cycles, biodiversity is essential to the
creation of ecosystem services.
An overview of ecosystem services and how they are valued is given in this paper. The total economic value is made up of
both non-use and use values, such as the market values of goods and services and the intrinsic values of ecosystems and
biodiversity.
This paper provides examples of how an ecosystem approach has resulted in the achievement of multiple outcomes, as
well as new opportunities for developing markets for ecosystem services that were previously undervalued.
1. INTRODUCTION
Human societies have long recognized how dependent they are on the products and services offered by
nature, particularly fiber, fuel, and food. The importance of intangible services, like soil fertility, water filtration,
climate control, and cultural and recreational benefits, has come to light in recent years. It is becoming
increasingly important to quantify and value these "ecosystem services" within economic and management
frameworks as our understanding of how dependent humans are on natural processes at various temporal and
spatial scales grows.
Definition of Ecosystem Services
Ecosystem services are the benefits provided to humans through the transformations of resources (or
environmental assets, including land, water, vegetation and atmosphere) into a flow of essential goods and
services e.g. clean air, water, and food (after Constanza et al. 1997).
Natural ecosystems have historically been altered by humans to benefit species that produce obvious benefits,
such as agricultural commodities, while usually ignoring the invisible but crucial ecosystem services, such as
pollination, soil fertility, insect control, and erosion control, which are costly and occasionally impossible to
replace if lost.
Certain ecosystem services, like water flow, nutrient movement, and climate regulation and stabilization, have
been even less evident until recently, when disruptions to these systems have made climate change, soil
erosion, and eutrophication worse. Ecosystems, like all complex systems, can seem to be functioning normally
up until they abruptly collapse because the underlying foundation may have deteriorated without any clear
warning signs. Fisheries are a well-known example of an industry that can suddenly collapse even in cases
where catch levels have been steady for years (Mullon et al. 2005).
,The landscape, where native vegetation has been replaced by pastures and crops, is another example. Because
of their shallow root systems, they don't absorb as much irrigation water or rainfall as native plants do. Up to
ten times faster, the extra water finds its way to the groundwater. This causes groundwater levels to gradually
rise, which dissolves the natural salt present in the worn soils that cover a large portion of Australia. These
alterations may not cause salt to appear on the surface of the land or enter streams for ten to one hundred
years (Australian State of the Environment Committee 2001). Production and biodiversity may suffer greatly as
a result of this.
Understanding and appreciating ecosystem services, as well as incorporating them into economic frameworks,
become crucial when externalities like restoring degraded river systems become a significant financial burden
on society. This is because many ecosystem services are difficult to observe until they stop flowing, which is
why they have not been formally counted in economic systems.
Therefore, preserving natural ecosystems and the services they offer is crucial for long-term community
well-being, economic growth, and efficiency. Even though it hasn't been their primary goal, the wide range of
public and private biodiversity protection measures have been essential in ensuring that ecosystem services
continue to flow.
Emerging concerns are examined in this paper.
● Recognizing the benefits even though we are still unable to precisely quantify them, as well as
identifying, measuring, and valuing ecosystem services
● Using what you've learned to conserve biodiversity and manage the environment and its resources.
2. ESSENTIAL IDEAS: BIODIVERSITY, RESILIENCE, AND ECOSYSTEMS
An ecosystem is a dynamic community that consists of populations of microorganisms, plants, animals, and other living
things interacting as a single functional unit. The presence and distribution of ecosystems are determined by
environmental factors, including soil type, landscape position, climate, and water availability. Sunlight, soil, nutrients, and
water are ecosystems' primary inputs; waste products from one component of the system serve as fuel for other
components. The self-regeneration of biomass, or carbon-based life, is a crucial result.
An ecosystem works by continuously cycling materials and energy through living things that develop, procreate, and
eventually pass away. Over millions of years, in response to a variety of stresses—such as diseases or droughts—and
ecological interactions—such as competition or predation—the cycling of materials and energy through living things has
changed. The ability of species and ecosystems to survive and adapt is called into question by recent changes in the
frequency and intensity of these disturbances and stresses.
Ecosystems are frequently altered to suit societal demands, necessitating the addition of potentially harmful or beneficial
inputs like fuel, fertilizers, and pesticides. Commodity production is one of the advantages, but pesticides or fertilizers
that wash into streams can degrade the water's quality. In addition, towns and cities can be seen as altered,
human-dominated ecosystems that produce concentrated waste streams that are naturally detoxified and absorbed.
These ecosystems depend on flows of resource inputs from which energy, water, and materials are extracted and used to
support human wellbeing and culture. Reusing and recycling waste materials more often can be thought of as a way to
change ecosystems into a more cyclical form that is more in line with the structure of natural ecosystems.
, The foundation of ecosystem services is Biodiversity
The ability to provide ecosystem services depends on biodiversity, which is made up of genetic variation in plants,
animals, and microorganisms as well as how these populations are organized into ecosystems. Numerous services,
including food and fiber, are directly derived from the diversity of organisms. Through their involvement in the energy
and material cycles, organisms also serve as the foundation for other services, such as clean air and water. The ability of
an ecosystem to generate and provide essential services is directly impacted by changes in and loss of biodiversity, which
can also have an impact on the ecological, economic, and social systems' long-term capacity to adapt and respond to
external pressures.
There is continuous scientific discussion and extensive research on the intricate nature of the relationship that exists
between biodiversity, ecosystem resilience, and the generation of ecosystem services (Haberl et al. 2005, Ridder 2008).
Several significant concerns have been identified, including:
● It is obvious that species diversity affects an ecosystem's ability to generate services. Maintaining ecosystem
services requires conserving or restoring the ecosystems' structure and, consequently, their ability to function, as
opposed to merely maximizing the number of species present. Maintaining the underlying structure is crucial
because the various structural components of ecosystems change under different disturbances or stresses at
different rates and scales.
● It is less evident to what extent biodiversity richness is required to sustain ecosystem service production. There is
often some functional redundancy or duplication among the species that make up ecosystems. Nevertheless, lost
species diversity is typically difficult or impossible to replace, so that does not make those species expendable or
replaceable. Therefore, maintaining biodiversity richness is probably going to act as a kind of natural insurance
against the eventual loss of ecosystem services (see Cork et al. 2007).
● Not all ecosystem services are produced by a single ecosystem. For example, water flows through and is
influenced by numerous ecosystems, all of which depend on one another to maintain adequate levels of water
quality and volume.
Food and fiber production services can be provided by modified ecosystems, but productivity depends on the underlying
ecosystem services continuing to exist. When thinking about the long-term maintenance of all ecosystem services, the
degree to which ecosystems are modified to produce services—along with specific management interventions and the
additional use of fertilizers, herbicides, insecticides, and water—become significant. A persistent emphasis on some
services (like food) at the expense of others (like nutrient cycling or soil formation) may eventually jeopardize the
sustainability of the ecosystems that supply these services.
It's common to underestimate and have a poor understanding of the role that biodiversity plays in preserving vital
services in landscapes that humans have altered.
Little areas of native vegetation can offer significant ecosystem services, such as serving as dispersal sources, refugia
(places to survive in unfavorable conditions), and stepping stones to larger patches. It has been proposed, for instance,
that these remnants could serve as a source and refuge for grassland specialists, which could aid in the restoration and
preservation of grasslands on a landscape scale. Remaining forests in agricultural landscapes are thought to be crucial in
temperate Australia because they provide a source of seeds for the regeneration of woodland ecosystems (Michaels et
al. 2008).
Compared to complex ecosystems, modified ecosystems are typically less resilient to external pressures (such as changes
in climate) due to their simpler ecological makeup. As a result, in order to continue providing services over the long run,
they run a higher risk of failing or requiring more artificial inputs (Walker and Salt 2006). An ecosystem's current
condition does not always predict its future state, particularly when confronted with extreme or changing circumstances
or events (Fischer et al. 2006).
