“…Climate change and anticipated increase in water consumption owing to the burgeoning human population are projected to exacerbate water scarcity problems. For instance, water consumption is expected to increase by 18% and 50% in developed and developing countries, respectively, in 2025 (Setegn & Donoso, 2015). Consequently, about 1.8 billion people worldwide are expected to face acute water shortages for domestic, agriculture and industrial purposes (Yannopoulos et al, 2019).…”

In dryland areas, integrating biochar soil amendment with in situ rainwater harvesting systems may decrease soil erosion, improve soil quality, and increase crop productivity and yield. This study was conducted to investigate the effect of maize straw biochar amendment and ridge‐furrow rainwater harvesting systems on run‐off, sediment yield and the physico‐chemical properties of a Calcic Cambisol soil in semiarid areas. The experiment was conducted on alfalfa (Medicago sativa) production land at the Anjiagou Catchment experimental station in Gansu province, China. The experimental layout was a split‐plot design with three replications. Biochar was applied at a rate of 0 and 30 t ha−1, respectively. The tillage treatments were flat planting, open‐ridging, and tied‐ridging (TR). Overall, the integration of maize straw biochar with TR decreased soil bulk density at 0–40 cm depth. Biochar application reduced run‐off by 37.8% and soil loss by 55.5% during alfalfa‐growing seasons compared to the control. In general, biochar addition increased soil total potassium, but the same effect was not observed for soil pH, total nitrogen, total phosphorus, and available phosphorus. These findings demonstrate the potential of integrating maize straw biochar and tillage systems to reduce soil erosion and improve soil quality for rainfed crop production in semiarid areas. Further studies on the effect of biochar‐tillage system interaction are warranted to improve soil conditions for plant growth and increase crop yield in dryland areas.

“…Esto provoca que las redes de monitoreo y las bases de datos sean cada vez más escasas, a pesar de que se ha demostrado que el análisis espacial de variables hidrológicas permite mejorar el conocimiento de los factores que ayudan a disminuir el riesgo por fenómenos extremos (Carrera-Hernández y Gaskin, 2007;Jacobi et al, 2013;Welz y Krellenberg, 2016). Es decir, la estimación del riesgo y la vulnerabilidad requiere conocer procesos cada vez más complejos y se precisan análisis probabilísticos más detallados para enfrentar la ocurrencia en el tiempo y el espacio de fenómenos extremos cada vez más severos (Gutiérrez-López et al, 2015).…”

Uno de los principales problemas en la gestión del agua en Latinoamérica y el Caribe es sin duda la escasa red de estaciones climatológicas e hidrométricas. La estimación de los eventos de diseño de las obras hidráulicas será tan buena como tan buena sea la calidad de la información utilizada. La calidad de la información se encuentra asociada con circunstancias como el proceso de recolección de mediciones, la longitud de los registros y la representatividad de la información en el sitio; en este sentido, el hidrólogo se enfrenta a dos problemas complejos. El primero consiste en tener las herramientas adecuadas para llevar a cabo una crítica aceptable de los datos a utilizar, lo que conlleva a definir conceptos muy precisos y seguirlos. El segundo es la necesidad de diseñar proyectos en sitios donde los datos climatológicos o los registros hidrométricos son escasos o nulos. Este trabajo presenta el detalle de los conceptos y las seis reglas que deben respetarse cuando se realiza una regionalización hidrológica con el objeto de transferir información hidrológica: (i) Caracterizar la variabilidad (espacio-temporal) de las mediciones, (ii) Identificar las variables que describen el fenómeno a estimar, (iii) Verificar la homogeneidad e independencia de las series de tiempo, (iv) Identificar regiones hidrológicamente homogéneas, (v) Construir ecuaciones regionales de transferencia de información y (vi) Verificar la validez de las ecuaciones regionales. Con este trabajo se pretende que los estudios de regionalización hidrológica se presenten de manera adecuada en países donde la transferencia de información es de gran importancia para el diseño de obras hidráulicas.

Integrated water resources management and the land‐water nexus: A South African perspective

As a source of diffuse pollution, land use/land cover (LULC) can have profound impacts on water quality. Accordingly, the importance of managing the land‐water nexus is often emphasized in the rhetoric of Integrated Water Resources Management (IWRM). Several authors, however, have cautioned that this need is frequently overlooked in practice. This is partly because stakeholders and policymakers are not equipped with clear and accessible information about the impacts of LULC on water resources and the consequent need to manage both in a sustainable and coordinated manner. The result is persistent sectoral fragmentation in the management of these two resources, and a concomitant failure to develop proactive and data‐driven catchment management strategies. Aimed principally at academics, researchers, and policymakers, this article argues that there is an urgent need, especially in developing countries such as South Africa, for ongoing research into the impacts of LULC on water resources. More particularly, there is a need to develop accurate models that will provide stakeholders and policymakers with the motivation, knowledge, and understanding necessary to develop effective, informed, and coordinated management strategies. A failure to do so, as illustrated by the current situation in South Africa, may have dire socioeconomic and ecological consequences.
