The Ecophysiology and Biotechnology, Polymers and Advanced Materials, Ecological Innovation and Development, and Plant Immunity and Biochemistry research groups at the Universitat Jaume I in Castelló have obtained nearly 450,000 euros to carry out two projects in the agri-food sector in the Valencian region (AGROALNEX) as part of the Recovery, Transformation and Resilience Plan (PRTR) funded by the European Union – Next Generation EU.

The Valencian regional government, through its Department of Innovation, Universities, Science and the Digital Society, had launched a call for applications for these subsidies with the aim of promoting the transformation of the agri-food sector towards a greener, healthier, more sustainable and more digital scenario to bridge the gap between scientific discoveries, the development of technologies and their implementation.

The study **“Development of an active and biocircular agricultural padding film”**, coordinated by Luis Cabedo Mas, of the [Polymers and Advanced Materials](https://www.uji.es/serveis/ocit/base/grupsinvestigacio/detall?codi=239) (PIMA) research group, and José María Lagarón Cabello, from the Food Safety and Conservation area of the [Institute of Agrochemistry and Food Technology](https://www.iata.csic.es/es/investigacion) (IATA), is intended to develop a biodegradable and agrocompostable film capable of encapsulating and releasing active agents that cause a plant immune response. José Gámez Pérez (PIMA), Rosario Vidal Nadal ([Green Innovation & Development](https://www.uji.es/serveis/ocit/base/grupsinvestigacio/detall?codi=016)) and Victoria Pastor Fuentes ([Plant Immunity and Biochemistry Group](https://www.uji.es/serveis/ocit/base/grupsinvestigacio/detall?codi=246)) are also taking part in the project.

The main contribution of [ActiBioMulch](mailto:https://agroalnextgva.umh.es/2023/10/06/058-actibiomulch/) to the circular economy is in providing more sustainable plastics for the agricultural sector that, at the same time, play an active role in combating pests. This reduces the use of conventional plastics and biocides in agriculture, which prevents the degradation and contamination of soil and water, as well as the introduction of these compounds into the food chain.

Given the fact that plants are constantly exposed to different stresses, the impact that the use of controlled release molecules has on the environment and agriculture will represent an advance in biology, biochemistry and plant physiology. At the same time, having a relatively constant inducer concentration will allow a more efficient defensive response using sustainable treatments.

The main aim of the **“Implementation of new techniques to increase the resilience of citrus-growing to climate change”** project, coordinated by Aurelio Goméz Cadenas and Carolina Clausell Terol of the [Ecophysiology and Biotechnology](https://www.uji.es/serveis/ocit/base/grupsinvestigacio/detall?codi=122) group, is to generate scientific knowledge and technological development applied to citrus cultivation and the protection of water resources, thereby contributing to improving people's quality of life. Specifically, the project focuses on the sustainable use of water resources in agriculture and improving the adaptation of citrus fruits to climate change. On the one hand, the amount of water used in the irrigation of citrus fruits will be considerably reduced through physiological and agronomic approaches, while, on the other, new palliative treatments, based on clean techniques for delayed delivery, will make it possible to reduce impact of water stress on the trees bearing these crops.

This approach will contribute to reducing the water footprint of citrus cultivation in the Mediterranean area while increasing the resilience of citrus trees to climate change. Citrus-growing will only be sustainable if it is able to maintain the quantities and qualities of harvests in a situation where less water is available, and this approach will contribute to achieving this goal.
