Overview
Background
The sustainable
development of forests has emerged as one of the most difficult,
serious, and pressing environmental issues of our time. Human-induced
changes in Earth's forests have affected natural resource
availability, biodiversity, atmospheric composition, and climate.
Satellite observations provide a unique source of consistent
information about forests over wide areas in a short period
of time. Such observations are necessary to begin understanding
the complex feedback processes between forests and climate
change. They also provide resource managers with the information
they need to assess the current state of the forests, weigh
the requirements of different uses by multiple stakeholders,
and manage forestland resources in a sustainable manner. It
is important to recognize, however, that the information provided
from satellites complements, but does not replace, the detailed
information obtained form aerial photography and ground-based
measurements.
Global
Observation of Forest and Land Cover Dynamics (GOFC-GOLD)
is a coordinated international effort working to provide ongoing
space-based and in-situ observations of forests and other
vegetation cover, for the sustainable management of terrestrial
resources and to obtain an accurate, reliable, quantitative
understanding of the terrestrial carbon budget. Originally
developed as a pilot project by the Committee on Earth Observation
Satellites (CEOS)
as part of their Integrated Global Observing Strategy, GOFC-GOLD
is now a panel of the Global Terrestrial Observing System
(GTOS).
GOFC-GOLD
is working to accomplish its objectives by:
- Providing
a forum for users of satellite data to discuss their needs
and for producers to respond through improvements to their
programs;
- Providing
regional and global datasets containing information on:
-
Location of different forest types;
-
Major changes in forest cover;
-
Biological functioning of forests (this will help quantify
the contribution forests make as absorbers and emitters
of greenhouse gases).
- Promoting
globally consistent data processing and interpretation methods;
- Promoting
international networks for data access, data sharing, and
international collaboration;
- Stimulating
the production of improved products.
Potential
users of GOFC-GOLD products include global change researchers,
international agencies, national governments, non-governmental
organizations, and international treaties and conventions
(such as the Framework Convention on Climate Change). One
of the most important challenges facing GOFC-GOLD is to develop
methods and implement systems that provide both research and
operational information on a regular sustained basis.
