  • The concept of forest sustainability dates from centuries ago, although the understanding of sustainable forest management (SFM) as an instrument that harmonizes ecological and socio-economic concerns is relatively new. The change in perspective occurred at the beginning of the 1990s in response to an increased awareness of the deterioration of the environment, in particular of the alarming loss of forest resources. The main and most striking cause of this deterioration is the deforestation occurring in some areas of the world.

  • Conserving biodiversity and the ecosystem services that they provide is part of the larger objective of promoting human well-being and sustainable development. The Millennium Ecosystem Assessment (MEA) 2005 has brought about a fundamental change in the way that scientists perceive the role and value of biodiversity, and recognizes the dynamics and linkages between people, biodiversity and ecosystems. Human activities have direct and indirect impacts on biodiversity and ecosystems, which in turn affects the ecosystems services that they provide, and ultimately human well-being.

  • Since a falling apple around 1665 worked its magic in the imaginative mind of a youthful farmer at Woolsthorpe in Lincolnshire, the meaning of the word action and of the equal and opposite reaction, has been investigated in science and technology. More than 300 years ago this irreversible process had consequences that led to the development of a theory of gravitation still used by space agencies even today.

  • An ecosystem is a biotic (organic) community joined with the abiotic (inorganic) conditions it lives in. Abiotic factors determine the kind of biotic community that will be found in a given area because the biotic community is both supported by and limited by the abiotic factors. Ecosystems are important because they are the functional units of sustainable life on Earth, making them models of the cycles that produce sustainability.

  • Remote sensing has been defined as the detection, recognition, or evaluation of objects by means of distant sensing or recording devices. In recent decades, remote sensing technology has emerged to support data collection and analysis methods of potential interest and importance in forest management. Historically, digital remote sensing developed quickly from the technology of aerial photography and photointerpretation science. In forestry, information extracted visually from aerial photographs is well-understood, well-used, and integrated with field surveys.
