Water resource management in the context of "Water scarcity"

Land management is the process of managing the use and development of land resources. Those resources are used for a variety of purposes for example agriculture, forestry, water resource management, human settlements and tourism. One aim of land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion. Unsustainable land managements leads to land being over- or misused which in turn degrades the land, reduces productivity and disrupts natural equilibriums.

Sustainable land management (SLM) is the set of practices and technologies that aim to integrate the management of land, water, and other environmental resources to meet human needs while ensuring long-term sustainability, ecosystem services, biodiversity, and livelihoods. Sustainable forest management is a sub-category of sustainable land management.

Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία (-logía) 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and drainage basin sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.

Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality.

Environmental resource management or environmental management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors between meeting needs and protecting resources. It is thus linked to environmental protection, resource management, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, wildlife management, environmental management systems, and others.

Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the atmosphere. It covers both water evaporation (movement of water to the air directly from soil, canopies, and water bodies) and transpiration (evaporation that occurs through the stomata, or openings, in plant leaves). Evapotranspiration is an important part of the local water cycle and climate, and measurement of it plays a key role in water resource management and agricultural irrigation.

The Paracas culture was an Andean society existing between approximately 800 BCE and 100 BCE, located in what today is the Ica Region of Peru. The Paracas people had extensive knowledge of irrigation and water management and made significant contributions in the textile arts. Most of the information about the lives of the Paracas people comes from excavations at the large seaside Paracas site on the Paracas Peninsula, first formally investigated in the 1920s by Peruvian archaeologist Julio Tello.

The Paracas Cavernas are shaft tombs set into the top of Cerro Colorado, each containing multiple burials. There is evidence that over the centuries when the culture thrived, these tombs were reused. In some cases, the heads of the deceased were taken out, apparently for rituals, and later reburied. The associated ceramics include incised polychrome, "negative" resist decoration, and other wares of the Paracas tradition. The associated textiles include many complex weave structures, as well as elaborate plaiting and knotting techniques.

The Nunavut Land Claims Agreement (NCLA, French: L'Accord sur les revendications territoriales du Nunavut) was signed on May 25, 1993, in Iqaluit, by representatives of the Tunngavik Federation of Nunavut (now Nunavut Tunngavik Incorporated), the Government of Canada and the Government of the Northwest Territories. This agreement gave the Inuit of the central and eastern Northwest Territories a separate territory called Nunavut. It is the largest Aboriginal land claim settlement in Canadian history.

The NLCA consists of 42 chapters, which address a broad range of political and environmental rights and concerns including wildlife management and harvesting rights, land, water and environmental management regimes, parks and conservation areas, heritage resources, public sector employment and contracting, and a range of other issues. The agreement defines two geographic areas covered by the agreement: the first consists of the Arctic islands and the mainland eastern Arctic, and their adjacent marine areas; the second includes the Belcher Islands, and associated islands and adjacent marine areas.
