Water security in the context of "Southern Nevada"

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.

WASH (or WatSan, WaSH; stemming from the first letters of "water, sanitation and hygiene") is a sector in development cooperation, or within local governments, that provides water, sanitation, and hygiene services to communities. The main purposes of providing access to WASH services are to achieve public health gains, implement the human right to water and sanitation, reduce the burden of collecting drinking water for women, and improve education and health outcomes at schools and healthcare facilities. Access to WASH services is an important component of water security. Universal, affordable, and sustainable access to WASH is a key issue within international development, and is the focus of the first two targets of Sustainable Development Goal 6 (SDG 6). Targets 6.1 and 6.2 aim for equitable and accessible water and sanitation for all. In 2017, it was estimated that 2.3 billion people live without basic sanitation facilities, and 844 million people live without access to safe and clean drinking water. The acronym WASH is used widely by non-governmental organizations and aid agencies in developing countries.

The WASH-attributable burden of disease and injuries has been studied in depth. Typical diseases and conditions associated with a lack of WASH include diarrhea, malnutrition, and stunting, in addition to neglected tropical diseases. There are additional health risks for women, for example, during pregnancy and birth, or in connection with menstrual hygiene management. Chronic diarrhea can have long-term negative effects on children in terms of both physical and cognitive development. Still, collecting precise scientific evidence regarding health outcomes that result from improved access to WASH is difficult due to a range of complicating factors. Scholars suggest a need for longer-term studies of technological efficiency, greater analysis of sanitation interventions, and studies of the combined effects of multiple interventions to better analyze WASH health outcomes.

Water crisis could refer to:

• Water security, a goal of water management and policy
• Water scarcity, a shortage of water in a specific geography, such as the Cape Town water crisis
• Drought, the meteorological conditions created by lack of precipitation

Nature-based solutions (or nature-based systems, and abbreviated as NBS or NbS) describe the development and use of nature (biodiversity) and natural processes to address diverse socio-environmental issues. These issues include climate change mitigation and adaptation, human security issues such as water security and food security, and disaster risk reduction. The aim is that resilient ecosystems (whether natural, managed, or newly created) provide solutions for the benefit of both societies and biodiversity. The 2019 UN Climate Action Summit highlighted nature-based solutions as an effective method to combat climate change. For example, nature-based systems for climate change adaptation can include natural flood management, restoring natural coastal defences, and providing local cooling.

The concept of NBS is related to the concept of ecological engineering and ecosystem-based adaptation. NBS are also related, conceptually to the practice of ecological restoration. The sustainable management approach is a key aspect of NBS development and implementation.

Environmental vegetarianism is the practice of vegetarianism that is motivated by the desire to create a sustainable diet, which avoids the negative environmental impact of meat production. Livestock as a whole is estimated to be responsible for around 15% of global greenhouse gas emissions. As a result, significant reduction in meat consumption has been advocated by, among others, the Intergovernmental Panel on Climate Change in their 2019 special report and as part of the 2017 World Scientists' Warning to Humanity.

Other than climate change, the livestock industry is the primary driver behind biodiversity loss and deforestation and is significantly relevant to environmental concerns such as water and land use, pollution, and unsustainability.

Climate change is posing an increasing threat to global socioeconomic development and environmental sustainability. Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. Climate change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.

The effects of these climatic changes have made already existing challenges with water security, food security and economic growth even more difficult. Harvests and agricultural production which account for about 33% of total Gross Domestic Product (GDP) are also at risk. The increased temperatures, rainfall variability in arid and semi-arid areas, and strong winds associated with tropical cyclones have combined to create favourable conditions for the breeding and migration of pests. An increase in temperature of up to 2.5 °C by 2050 is predicted to increase the frequency of extreme events such as floods and droughts.

Central California is generally thought of as the middle third of the U.S. state of California, north of Southern California (which includes Los Angeles and San Diego) and south of Northern California (which includes San Francisco and San Jose). It includes the northern portion of the San Joaquin Valley (which itself is the southern portion of the Central Valley, beginning at the Sacramento–San Joaquin River Delta), part of the Central Coast, the central hills of the California Coast Ranges and the foothills and mountain areas of the central Sierra Nevada.

Central California is considered to be west of the crest of the Sierra Nevada. East of the Sierra is Eastern California. The largest cities in the region (over 50,000 population), from most to least populous, are Sacramento, Fresno, Bakersfield, Stockton, Modesto, Elk Grove, Salinas, Visalia, Clovis, Tracy, Merced, Manteca, Turlock, Tulare, Madera, Lodi, Porterville, Santa Cruz, Hanford, and Delano. Over time, droughts and wildfires have increased in frequency and become less seasonal and more year-round, further straining the region's water security.

Fresno County (/ˈfrɛznoʊ/ ), officially the County of Fresno, is a county located in the central portion of the U.S. state of California. As of the 2020 United States census, the population was 1,008,654. The county seat is Fresno, the fifth-most populous city in California. Fresno County comprises the Fresno, CA Metropolitan Statistical Area, which is part of the Fresno–Madera, CA Combined Statistical Area. It is located in the Central Valley, south of Stockton and north of Bakersfield. Since 2010, statewide droughts in California have further strained both Fresno County's and the entire Central Valley's water security.

The Sacramento Valley is the area of the Central Valley of the U.S. state of California that lies north of the Sacramento–San Joaquin River Delta and is drained by the Sacramento River. It encompasses all or parts of ten Northern California counties. Although many areas of the Sacramento Valley are rural, it contains several urban areas, including the state capital, Sacramento.

Comparatively water-rich relative to the other segment of the Central Valley to the south, the San Joaquin Valley, there are slight differences in the crops typically grown in the Sacramento Valley. Much wetter winters (averaging between 25–60 inches (640–1,520 mm) of annual precipitation in the nearby foothills) and an extensive system of irrigation canals allows for the economic viability of water-thirsty crops such as rice and rootstock walnuts. Since 2010, statewide droughts in California (combined with unprecedented summer heat) have strained both the Sacramento Valley's and the Sacramento metropolitan region's water security.
