Concept Definition Deliverable(s)
sustainable development goals

A set of goals adopted by the United Nations on September 25, 2015 to end poverty, protect the planet, and ensure prosperity for all as part of a new sustainable development agenda. Each goal has specific targets to be achieved over the next 15 years.

Scenarios and models assessment, Asia-Pacific assessment, Sustainable use assessment
sustainable development goals

Also, the Global Goals, are a universal call to action to end poverty, protect the planet and ensure that all people enjoy peace and prosperity. These 17 Goals build on the successes of the Millennium Development Goals, while including new areas such as climate change, economic inequality, innovation, sustainable consumption, peace and justice, among other priorities. The goals are interconnected; often the key to success on one will involve tackling issues more commonly associated with another.

sustainable development goals

A set of goals adopted by the United Nations in 2015 to end poverty, protect the planet, and ensure prosperity for all, as part of the 2030 Agenda for Sustainable Development.

Americas assessment, Africa assessment, Europe and Central Asia assessment
sustainable development

Development that meets the needs and aspirations of the current generation without compromising the ability to meet those of future generations.

Sustainable use assessment
sustainable forest management

Can mean many things to many people - yet a common thread is the production of forest goods and services for the present and future generations. The concept provides guidance on how to manage forests to provide for today’s needs (as best as possible) and not compromise (i.e. reduce) the options of future generations.

Land degradation and restoration assessment
sustainable intensification

A process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non- agricultural land.

Land degradation and restoration assessment, Pollination assessment
sustainable intensification

The goal of sustainable intensification is to increase food production from existing farmland while minimizing pressure on the environment. It is a response to the challenges of increasing demand for food from a growing global population, in a world where land, water, energy and other inputs are in short supply, overexploited and used unsustainably.

sustainable intensive agriculture

Process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non-agricultural land.

Land degradation and restoration assessment
sustainable land management

The use of land resources, including soils, water, animals and plants for the production of goods to meet changing human needs while ensuring the long- term productive potential of these resources and the maintenance of their environmental functions.

Land degradation and restoration assessment
sustainable land use

The land use that serves the needs (for food, energy, housing, recreation etc.) of all human beings living on Earth today and in the future, respecting the boundaries and the resilience of ecological systems.

Land degradation and restoration assessment
sustainable livelihood

Sustainable livelihoods is defined as the ability of the users to cope with and respond to the stresses and shocks related to fluctuations in the Nature’s contribution to people that adversely impact their material, relational and subjective dimensions of life and create vulnerabilities, develop their capabilities to strengthen access and entitlements to the variety of livelihood resources, without unnecessarily undermining the natural resource base (the wild species and its natural environment), so as to achieve a desirable standard of living that befits them as humans and also approved by the measures of wellbeing and human development.

Sustainable use assessment
sustainable soil management

Sets of activities that maintain or enhance the supporting, provisioning, regulating and cultural services provided by soils without significantly impairing either the soil functions that enable those services or biodiversity.

Land degradation and restoration assessment
sustainable use

The use of components of biological diversity in a way and at a rate that does not lead to the long-term decline of biological diversity, thereby maintaining its potential to meet the needs and aspirations of present and future generations (CBD, 1992).

Global assessment (1st work programme)
sustainable use (of biodiversity and its components)

The use of components of biological diversity in a way and at a rate that does not lead to the long-term decline of biological diversity, thereby maintaining its potential to meet the needs and aspirations of present and future generations.

Land degradation and restoration assessment, Asia-Pacific assessment, Americas assessment, Africa assessment, Europe and Central Asia assessment
sustainable use

Sustainable use is defined by the Convention on Biological Diversity since 1992 as “the use of components of biological diversity in a way and at a rate that does not lead to the long-term decline of biological diversity, thereby maintaining its potential to meet the needs and aspirations of present and future generations.” This assessment notes that sustainable use is also an outcome of social-ecological systems that aim to maintain biodiversity and ecosystem functions in the long term, while contributing to human well-being. It is a dynamic process as wild species, the ecosystems that support them and the social systems within which uses occur, change over time and space. This assessment notes the social, economic, and environmental dimensions of sustainability as identified by the 2030 Agenda for sustainable development and its Sustainable Development Goals.

Sustainable use assessment
sustainably-intensified agriculture

Any system that is designed to produce high yields but with careful management and selection of inputs to reduce harm to the environment. It includes development and use of crop and animal varieties better suited to their environment, use of new technology for pest and disease control and for input management.

Asia-Pacific assessment
swidden agriculture

Global assessment (1st work programme)
swidden

Swidden farming, also known as shifting cultivation or milpa in Latin America, is conventionally defined as an agricultural system in which temporary clearings are cropped for fewer years than they are allowed to remain fallow.

Land degradation and restoration assessment

Scenarios and models assessment
uncertainty

Any situation in which the current state of knowledge is such that: the order or nature of things is unknown, the consequences, extent, or magnitude of circumstances, conditions, or events is unpredictable, and credible probabilities to possible outcomes cannot be assigned. Uncertainty can result from lack of information or from disagreement about what is known or even knowable. Uncertainty can be represented by quantitative measures (e.g., a range of values calculated by various models) or by qualitative statements (e.g., reflecting the judgment of a team of experts).

The following have been identified as IPBES units of analysis globally: Terrestrial: Tropical and subtropical dry and humid forests Temperate and boreal forests and woodlands Mediterranean forests, woodlands and scrub Tundra and High Mountain habitats Tropical and subtropical savannas and grasslands Temperate Grasslands Deserts and xeric shrublands Wetlands - peatlands, mires, bogs Urban/Semi-urban Cultivated areas (incl. cropping, intensive livestock farming etc.) Aquatic, including both marine and freshwater: Cryosphere Aquaculture areas Inland surface waters and water bodies/freshwater Shelf ecosystems (neritic and intertidal/littoral zone) Open ocean pelagic systems (euphotic zone) Deep-Sea Coastal areas intensively used for multiple purposes by humans These IPBES terrestrial and aquatic units of analysis serve as a framework for comparison within and across assessments and represent a pragmatic solution. The IPBES terrestrial and aquatic units of analysis are not intended to be prescriptive for other purposes than those of IPBES assessments. They are likely to evolve as the work of IPBES develops.
