This study explores the use of brackish water in irrigation as a potential solution to the growing problem of water scarcity in agriculture. With freshwater resources becoming increasingly limited, brackish water offers an alternative that could help maintain agricultural productivity. The study employs a salinity calculation model combined with a hydrological model to assess the impact of brackish water on soil and crop performance. Key factors such as water source salinity, crop water requirements, irrigation methods, and soil properties are considered in the model.

The salinity model quantifies salt levels in irrigation water and predicts potential risks such as soil salinization, which could negatively affect crop yields and soil fertility. By understanding how salt accumulates in the soil, the model helps identify crops that are more tolerant to saline conditions and suggests appropriate irrigation management strategies to minimize salt buildup. The study emphasizes the importance of selecting salt-tolerant crops and adjusting irrigation practices to mitigate salinity's negative effects.

This research also highlights the need for efficient water use in regions facing water shortages. By using brackish water for irrigation, valuable freshwater resources can be conserved for other uses, while still supporting agricultural production. The findings of this study provide practical guidelines for managing brackish water in agriculture, helping to preserve soil fertility, improve water use efficiency, and enhance long-term crop production. Ultimately, with proper management, brackish water can serve as a sustainable solution to the challenges of water scarcity in agriculture.

The group was tasked with designing a one-day ahead forecast model of the Danube River streamflow, for the section located near Vienna, Austria, and the Freudenau power plant, and to discuss the impacts of damming the river. This objective was accomplished using historical average daily datasets for inflow (m3/s), temperature (°C), and precipitation (mm/d) from 1990-2016. This dataset was further divided into a training subset from 1990-2004 (15 years) and a calibration subset from 2005-2016 (12 years).

The green hydrogen system designed in series with a solar power plant for La Gujaria, Colombia, incorporated detailed technology specifications and economic analysis. A 30-year financial roadmap was developed, considering policies and incentives, and included ROI, CAPEX, OPEX, and revenue projections. The system was estimated to recover the initial investment by the third year, with a 25% annual profit increase. By the 25th year, the system achieved a 72% net profit margin and an overall net profit of 800% of the initial investment, proving to be both economically and environmentally beneficial. The study concluded that large-scale operations would enhance efficiency and facilitate a faster transition to sustainable energy.

The study analyzes the failures of the Convention on Biological Diversity (CBD), focusing on both technical challenges and the lack of effective policy implementation. It highlights the importance of addressing these issues to avoid similar failures in achieving the Sustainable Development Goals (SDGs). The research also identifies new alternatives and incentives to foster international partnerships and cooperation, emphasizing the concept of Apparatus Mundi as a means to bridge the gap between technical and political aspects of international treaties.

As a professional in sustainable irrigation expansion, I specialize in integrating salinity management practices to optimize water use in agriculture. I design and implement innovative irrigation systems that promote water efficiency, prevent soil salinization, and ensure long-term agricultural productivity. My work involves analyzing water quality, soil conditions, and crop requirements to develop tailored solutions that address water scarcity and salinity challenges. I leverage advanced irrigation technologies and monitoring tools to improve sustainability in agricultural systems, while exploring alternative water sources and management strategies to support food security and environmental conservation.

The course covers key concepts in water, land, and landscape, starting with an overview of the water cycle and its importance in infrastructure design. It delves into hydrological processes such as precipitation, infiltration, evapotranspiration, and runoff, emphasizing their quantification. The role of soil parameters in hydrology is explored, along with watershed management practices. River morphology and restoration techniques are examined, along with flood and drought risk management strategies. The course also focuses on water infrastructure and urban hydrology, comparing nature-based solutions to traditional methods for managing floods and droughts. Resource use, water management, and non-conventional water use methods, like wastewater reuse and desalination, are discussed, integrating theoretical frameworks with case studies.
