Towards integrated water resources management considering hydro-climatological scenarios: an option for sustainable development

Abstract

Background: In the rainfed areas, water, not land, is the foremost restraining resources for better agricultural production to satisfy the growing demand of food and other needs. Water harvesting and enhancing productivity of available water, and not volume of yield per units of land, is therefore a better solution for rainfed agriculture. Under these circumstances, it is necessary toimplement efficient and effective integrated water resources management practices. Elsewhere rainfed dependent highland parts of Ethiopia, in the Beressa watershed most of the rainwater lost in the form of runoff particularly during excess rainfall; therefore, the benefit of rainwater during less rainy season is insignificant. The objective of this study therefore was to assess crop water requirement and net irrigation requirement using CROPWAT8.0 model and Rainfall Contribution Index (RCI) for various crops and to describe the benefits of water harvesting and integrated and sustainable water resources management. Crops growing during the month of February to June (less rainy season) are among the highest irrigation requirements.Results: Based on RCI (as the value far from 1) reflect rainfall contribution is insufficient to satisfy the crop water requirements for the whole growth stages. Therefore, there is a need for supplemental irrigation and rainwater harvesting and a necessity for integrated water resources management. To reduce the intensity of water shortage therefore conservation planning and water management at watershed level in an integrated manner is critical. Similarly, soil and water conservation management practices is essential for the communities to reduce runoff and other resources for future uses and determine the optimal amount of water resources consumption at the irrigation fields is an urgent issues. Conclusions:As a result, there is a need to do more efforts related to water harvesting and integrated water resources management for the sustainability of agriculture and over all human survival. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Dynamics of land use and land cover changes in Huluka watershed of Oromia Regional State, Ethiopia

“…Many of them strongly affirm that it is vital to institutionalize sustainable biological and physical soil conservation measures to mitigate land degradation and improve the livelihood of the local community in the watershed (Amdihun et al 2014;Wolancho 2015;Wolka et al 2015;Yimer et al 2015;Tadesse et al 2017;Deribew and Dalacho 2019;Kidane et al 2019). Others assert that integrated water resources planning and management is vital as one of the elements of natural resources management (Laekemariam et al 2016;Qayum et al 2016;Seyoum 2016;Teshome 2016;Miheretu and Yimer 2017;Meshesha and Khare 2019). Others attest that payments for ecological services are vital for the sustainable management of natural resources (Tolessa et al 2017;Bogale 2020;Hasan et al 2020).…”

Ensemble machine learning paradigms in hydrology: A review

“…Ante el crecimiento poblacional, cambio climático natural e inducido por el hombre, es esencial disponer de herramientas y técnicas para garantizar la seguridad alimentaria continua. Programas de planificación agrícola han demostrado efectividad en brindar apoyo a la toma de decisiones (Meshesha and Khare, 2019;Randall et al, 2022) La planificación de cultivos se refiere al diseño de cultivos en tiempo y espacio determinado, tiendo en cuenta etapas de producción, transporte y comercialización (Hajimirzajan et al, 2021), En la etapa productiva se considera recomendaciones en fechas de siembra, practicas o labores, variedades, ciclos, rotaciones entre otras. La planificación además considera evaluar los impactos al ambiente, por lo que es considerada como una de las herramientas de la gestión ambiental.…”

Study of Yeh Embang Watershed Characteristics for Sustainable Water Management

“…Sustainable watershed management is a step that must be taken to maintain the sustainability of water resources in order to combat the effects of climate change on the Yeh Embang watershed. Analysis of watershed characteristics is one of the important components as the basis for the preparation of watershed management patterns [12]- [15].…”
