Technical geographyTechnical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information. The other branches, most commonly limited to human geography and physical geography, can usually apply the concepts and techniques of technical geography. However, the methods and theory are distinct, and a technical geographer may be more concerned with the technological and theoretical concepts than the nature of the data.
Land change scienceLand change science refers to the interdisciplinary study of changes in climate, land use, and land cover. Land change science specifically seeks to evaluate patterns, processes, and consequences in changes in land use and cover over time. The purpose of land change science is to contribute to existing knowledge of climate change and to the development of sustainable resource management and land use policy.
LandLand, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays important roles in Earth's climate system, being involved in the carbon cycle, nitrogen cycle, and water cycle.
Accaparement des terresL’accaparement des terres (en anglais, land grabbing) désigne de manière péjorative l'acquisition légale, et parfois controversée, de grandes étendues de terrains. Il s'agit souvent de terres agricoles dans des pays en développement, par des entreprises transnationales et gouvernementales. L'accaparement des terres est une notion polysémique qui recouvre des réalités diverses. Il s'agit principalement d'achats à grande échelle, le plus souvent par des entreprises étrangères, de terres.
