Resumen
La gestión estratégica de los acuíferos utilizando datos y políticas es esencial para maximizar los beneficios del riego. Este enfoque garantiza la utilización sostenible de los recursos hídricos para la agricultura.
Área de la Ciencia:
- Ciencias del medio ambiente
- Ciencias Agrícolas
- Hidrología
Sus antecedentes:
- Los acuíferos son recursos hídricos críticos para la agricultura mundial.
- Las prácticas de riego no sostenibles pueden conducir al agotamiento de los acuíferos.
- Las estrategias de gestión eficaces son necesarias para la seguridad hídrica a largo plazo.
Objetivo del estudio:
- Para destacar la necesidad de la utilización estratégica de los acuíferos en el riego.
- Hacer hincapié en la integración de conocimientos basados en datos y apoyo a las políticas.
- Promover la maximización de los beneficios derivados de los recursos acuíferos.
Principales métodos:
- Análisis de las prácticas de riego actuales y su impacto en los acuíferos.
- Revisión de los marcos políticos que influyen en la gestión de los recursos hídricos.
- Desarrollo de un modelo conceptual para el uso de acuíferos basado en datos y respaldado por políticas.
Principales resultados:
- El uso actual del acuífero para el riego a menudo carece de planificación estratégica.
- Las intervenciones políticas pueden orientar significativamente la extracción sostenible del agua.
- Los enfoques basados en datos mejoran la eficiencia y los beneficios del riego.
Conclusiones:
- Una estrategia coordinada que integre datos y políticas es vital para la gestión sostenible de los acuíferos.
- Maximizar los beneficios del acuífero requiere un cambio hacia el riego basado en la evidencia y regulado.
- La investigación futura debe centrarse en la aplicación y evaluación de dichas estrategias integradas.

Aquaporins
5.0K
Aquaporins or AQPs are a family of integral membrane proteins whose primary function is to transport water, while some called aquaglyceroporins also transport glycerol. In addition, aquaporins have also been suspected to be involved in transporting volatile substances, such as carbon dioxide and ammonia, across membranes. Such AQPs that act as gas channels are often highly expressed in cells involved in the gaseous exchange, such as red blood cells, epithelial cells, and pulmonary capillaries.

Quality of Water
173
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

States of Water
51.8K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Regulation of Water Output
373
The human body predominantly expels water through the urinary system. On average, an individual generates around 1.5 liters of urine each day. This amount can fluctuate based on how well a person is hydrated, but a critical minimum quantity of urine must be produced to ensure the body's proper functioning. Daily, the kidneys remove 600 to 1200 milliosmoles of dissolved substances, effectively excreting excess minerals and water-soluble toxins such as creatinine, urea, and uric acid from the...

Testing Water Quality
168
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Dialysis
779
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
