Digitalization and automatization of agricultural irrigation in Germany
Die Dürresommer der vergangenen Jahre (insbesondere 2018 und 2019) haben die Landwirte vor massive Wasserprobleme gestellt. Landwirtschaftliche Bewässerung nimmt in vielen Regionen in Deutschland stark an Relevanz zu. Hierbei kommt es zu Nutzungskonflikten zwischen Bewässerung und der Trinkwasserversorgung. Das Thema der wassersparenden Bewirtschaftung von landwirtschaftlichen Flächen wird aus der Sicht der Wirtschafts- und Nachhaltigkeitsdiskurse in Zukunft weiter an Bedeutung gewinnen. Die Bewässerung befindet sich in einer digitalen als auch technischen Transformation. Im Folgenden wird ein Überblick über die aktuellen Entwicklungen der Digitalisierung und Automatisierung von Bewässerungssystemen gegeben und daran anknüpfend wird auf aktuelle Forschungstätigkeiten eingegangen.Germany experienced historic droughts in the summers of 2018 and 2019. These events clearly indicate that irrigation will continue to become more relevant for the stability of the agricultural sector of multiple regions in Germany. Simultaneously, increased demand for irrigation water for agriculture correlates with increased intra-sectoral allocation conflict – especially with drinking-water suppliers and consumers. Water-use efficiency in the agricultural sector will become even more important given the economic and sustainability discourses that define our future. Irrigation is undergoing both a digital and a technical transformation. The following discussion provides an overview of the current developments in digitization and automation of irrigation systems for agriculture
Net-zero building designs in hot and humid climates: A state-of-art
Net Zero building is becoming a global trend as a strategy to reduce the carbon footprint. In order to achieve Net-Zero building design in hot and humid climates, efforts must be put to reduce the overall energy use to the maximum extent by integrating appropriate building technologies into the architectural designs. In this paper, the latest ideas dealing with building performances and net-zero building design projects, are reviewed and an outlook is given including new concepts of combined systems in hot and humid climate regions. The paper is structured in the following manner which includes basic guidelines, natural ventilation systems, cooling and dehumidification, insulation and construction materials, reviews of several net-zero energy building projects. The paper also proposes novel wind tower dehumidification design and ventilated attic building design for the hot and humid region. Thus the state of art review is presented for net-zero buildings in a hot and humid climate
