Summary
Land use change has reduced Earth's capacity to provide benefits by 10%, impacting agriculture, forestry, and medicine. Urgent action is needed to prevent further degradation and utilize natural recovery for ecosystem services.
Area of Science:
- Ecology
- Environmental Science
- Conservation Biology
Background:
- Land use change significantly impacts terrestrial ecosystems globally.
- Approximately 43% of Earth's vegetated land shows reduced capacity to supply human benefits.
- This degradation results in a substantial loss of potential direct instrumental value (PDIV).
Purpose of the Study:
- To quantify the impact of land use on ecosystem services.
- To project future losses of PDIV under current trends.
- To assess the potential for natural recovery of ecosystem functions.
Main Methods:
- Analysis of terrestrial vegetated surface impacts.
- Calculation of potential direct instrumental value (PDIV) reduction.
- Biophysical modeling to assess recovery potential.
Main Results:
- Recent land use has diminished the PDIV by approximately 10%.
- Without intervention, global PDIV loss could reach 20% by 2020.
- A feasible recovery of 5% PDIV is possible within 25 years through natural mechanisms.
Conclusions:
- Urgent strategies are required to mitigate land degradation.
- Harnessing natural recovery is crucial for retaining ecosystem values.
- Preventing irreversible damage to productive land is paramount for human well-being.

01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
02:26Ecological Disturbance
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
02:31Habitat Fragmentation
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
02:41Responses to Drought and Flooding
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
02:23The Soil Ecosystem
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
02:07Conservation of Declining Populations
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
