While most land administration systems traditionally have a primary objective of supporting the operation of land markets, they are increasingly evolving into a broader land information infrastructure which supports economic development, environmental management and social stability in both developed and developing countries.
As most land use systems (AF, AC) were only of small size (<2 ha), small-scale point counting was the only possible method, regardless of the fact that bird point diversity in tropical forests may only reflect a small proportion of the overall alpha-diversity [42].
The most spatially distinct land system was Skukuza, which exhibited some of the highest initial net primary production (NPP) values and also the greatest decreases in NPP into the future.
Spray irrigation systems are among the most land-intensive disposal systems.
Animals had to change their feeding and excretory systems, and most land animals developed internal fertilization of their eggs.
Since most significant human impacts on the land system can be captured at this scale, a number of researchers are focusing on such products.
Because of the major role of Northern Eurasia in the global land system, they find that most studies focus on the land processes (i.e., land and water carbon cycle, energy balance) or on the fate of the land system under climate change (permafrost thawing, agriculture, wildfire).
This perspective has also moved land system science from a focus on the most dramatic land cover changes to giving more attention to subtle changes of human interactions with the natural surroundings, including land management and the provisioning of a wide range of ecosystem services.
Most studies assessing the impacts of such events, however, have focused on land conversions (e.g., deforestation) and short time periods (i.e., decades), mainly because reliable and more comprehensive long-term historic datasets of land system change and its underlying drivers are missing for most parts of the world (Singh et al., 2013).
Most of the landing system is actually very similar to what brought Spirit and Opportunity to the surface.
