DESCRIBING RELATIONSHIPS: DIRECT AND INDIRECT DRIVERS OF BIODIVERSITY CHANGE<br />

Within the context of Figure 2.2, all organizations<br />

contribute to changes in biodiversity<br />

in some manner, either positively or negatively.<br />

The Millennium Ecosystem Assessment<br />

(MA) 11 provides a framework for those<br />

trying to categorize or describe the types of<br />

activities that can result in biodiversity<br />

change.<br />

It is vital to recognize that the depletion of<br />

ecosystem services is generally addressed at<br />

the local scale, even if the human activities<br />

and the effects (such as climate change,<br />

decreased supplies) are felt globally.<br />

ecosystem services and<br />

drivers of biodiversity<br />

change.<br />

• Changes in local land use and cover (e.g., land<br />

conversion resulting from real estate development,<br />

intensive farming on degraded land)<br />

• Species introduction or removal (e.g., invasive insects<br />

introduced in agricultural production to fight plant<br />

diseases, genetic engineering)<br />

• Technology adaptation and use (e.g., changed fishing<br />

practices to reduce by-catch, filters to reduce emissions)<br />

• External inputs (e.g., fertilizer use, pest control, irrigation<br />

to increase production)<br />

• Harvest and resource consumption (e.g., exploitation<br />

of natural resources, fisheries, bush meat)<br />

• Climate change (e.g., human activities contributing to<br />

global warming such as deforestation and use of fossil fuels)<br />

• Natural, physical, and biological drivers (e.g.,<br />

evolution, volcanoes)<br />

• Demographic (e.g., migration of workers as a result of<br />

new production activities, population growth)<br />

• Economic (e.g., globalization, international supply<br />

chains, market, policy framework)<br />

• Socio-political (e.g., governance, institutional and legal<br />

framework, conventions such as the Convention on<br />

Biological Diversity)<br />

• Science and technology (e.g., research results,<br />

Environmental Impact Assessment (EIA), innovations)<br />

• Cultural and religious (e.g., beliefs, consumption<br />

choices to reduce biodiversity impacts, green electricity)<br />

• Provisioning (e.g., food, water, fiber, fuel)<br />

• Regulating (e.g., climate regulation, water,<br />

disease)<br />

• Cultural (e.g., spiritual, aesthetic, recreation,<br />

education)<br />

• Supporting (e.g., primary production, soil<br />

formation)<br />
