Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

27.1K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Underflow Gates01:30

Underflow Gates

159
Underflow gates are vital for controlling water flow in irrigation canals. The three main types of underflow gates — vertical, radial, and drum gates — serve different purposes while ensuring effective flow management. Vertical gates move up and down, generating a free-flowing water jet; radial gates pivot to regulate the flow; and drum gates rotate for precise adjustments. The flow through these gates is influenced by downstream conditions, resulting in free or drowned outflow.Free and...

Key Elements for Plant Nutrition

23.2K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Water and Mineral Acquisition

34.3K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Regulation of Water Output01:26

Regulation of Water Output

1.6K
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...

Área de la Ciencia:

  • Ciencias Agrícolas Ciencias Agrícolas
  • Ciencias ambientales Ciencias ambientales.
  • Seguridad Alimentaria Mundial La seguridad alimentaria mundial es un hecho.

Sus antecedentes:

  • La humanidad se enfrenta al desafío de satisfacer el doble de la demanda de alimentos para 2050 en medio de la degradación ambiental de la agricultura.
  • Se propone una intensificación sostenible para aumentar los rendimientos y disminuir los impactos ambientales, pero sus implicaciones globales no están claras.

Objetivo del estudio:

  • Evaluar las perspectivas de intensificación global cerrando las brechas de rendimiento.
  • Para analizar los patrones espaciales de la gestión agrícola y las limitaciones de rendimiento.
  • Identificar los cambios de gestión necesarios para aumentar los rendimientos.

Principales métodos:

  • Evaluación a escala global de las brechas de rendimiento (diferencia entre los rendimientos observados y los alcanzables).
  • Análisis de los factores que controlan la variabilidad del rendimiento: uso de fertilizantes, riego y clima.
  • Evaluación de los cambios de gestión necesarios para el cierre de la brecha de rendimiento.

Principales resultados:

  • Cerrar las brechas de rendimiento podría aumentar la producción mundial en un 45% -70% para la mayoría de los cultivos.
  • La variabilidad del rendimiento está impulsada principalmente por el fertilizante, el riego y el clima.
  • Es posible reducir significativamente el impacto ambiental eliminando el uso excesivo de nutrientes, lo que permite un aumento de la producción de cereales de ~ 30%.

Conclusiones:

  • El cumplimiento de los objetivos futuros de seguridad alimentaria y sostenibilidad es alcanzable a través de cambios significativos en la gestión de nutrientes y agua.
  • La intensificación sostenible requiere estrategias de gestión regionales adaptadas para cerrar efectivamente las brechas de rendimiento.
