    This report reviews the terrestrial Essential Climate Variables (ECVs), which are endorsed by the United Nations Framework Convention on Climate Change (UNFCCC) and the Group on Earth Observations (GEO). Details are provided on why these observations are needed to understand the causes of climate change, analyse the potential impacts, evaluate the adaptation options and enable characterization of extreme events such as fl oods, droughts and heat waves. It highlights some of the activities being undertaken, the need for the standardization of methods and harmonization of data and the major observational gaps and funding requirements needed to allow countries and international agencies to monitor, implement and report on issues related to climate change.

    The observations, data and information that GTOS assists in providing to stakeholders, including the terrestrial Essential Climate Variables, continue to be required to assess the causes of climate change; to analyse the potential impacts; evaluate the adaptation options, and to enable the characterization of extreme events such as floods, droughts and heat waves.

    Land cover change is a pressing environmental issue, acting as both a cause and a consequence of climate change. Reliable observations are crucial to monitor and understand the ongoing processes of deforestation, desertification, urbanization, land degradation, loss of biodiversity, ecosystem functions, water and energy management, and the influence of land cover changes on the physical climate system itself. A number of disciplines (geography, ecology, geology, forestry, land policy and planning, etc.) use and refer to land cover and land cover change as one of the most obvious and detectable indicators of land surface characteristics and associated human induced and natural processes. Current and future IPCC Assessment Reports are based upon an uncertain understanding of the land surface dynamics and related processes. Applications of land cover and land dynamics in climate change-related Earth System Models and Impact Assessment Models need to be better linked and coordinated. The importance of these issues requires continuous monitoring systems and data.
