Brief Description:

Quinoa (Chenopodium quinoa Willd.) is a major Andean seed crop that has become a popular food product in Europe. Quinoa has a high potential to improve food security due to its stress-tolerance, genetic diversity, nutritional quality and low production costs. The United Nations declared 2013 the International Year of Quinoa, and the FAO emphasized the nutritional benefits and agricultural adaptability of quinoa.Quinoa seeds contain essential micronutrients, including vitamin E, pro-vitamin A carotenoids, and minerals, but also anti-nutritional saponins. Because of their bitter taste, saponins need to be removed before consumption, which is time- and resource-consuming and adds to the production costs. Breeding efforts therefore focus on producing quinoa accessions with low saponin content (‘sweet’). In floral clusters of ‘sweet’ accessions we observe a transcriptional down-regulation of many genes in the mevalonate (MVA) pathway, which results in saponin biosynthesis. The pathway is also involved in the synthesis of vitamin E, carotenoids, and phytosterols, which raises the question if the downregulation of the MVA pathway in ‘sweet’ quinoa also influences the content of these important and in part essential nutrients in quinoa seeds. Furthermore, if the contents of nutrients and anti-nutritional compounds are both altered, how does this affect their digestion, bioaccessibility and absorption in humans? This project brings together experts in plant science, saponins, and human nutrition to investigate the mechanisms regulating saponin and nutrient synthesis in quinoa and their impact on digestion and bioaccessibility of essential nutrients for humans.

Brief Description:

Quinoa is a pseudo-cereal, initially cultivated in the Andean region. It has gained attention throughout the Mediterranean because it yields well even on marginal soils and is tolerant to drought, soil salinity and other abiotic stresses. Moreover, it is considered among the world’s healthiest foods. Its grains contain a balanced composition of minerals, vitamins, dietary fibre, fats, and high-quality, gluten-free proteins with a balanced amino acid profile. Our vision considers the whole system by enabling successful and widespread agroecological quinoa farming and marketing its products.

Q4M brings together scientific partners and societal stakeholders from five Mediterranean countries (Tunisia, Algeria, Morocco, Spain and France) in collaboration with quinoa and breeding experts from Germany. Together, the consortium will advance climate-resilient quinoa germplasm and upscale quinoa cultivation and valorisation in an integrated approach. Guided by National priorities and reinforced by a multi-stakeholder network, we will demonstrate the power and benefits of agroecological quinoa farming at twelve distinct multi-agroecosystem demo sites. We will use various crop combinations under varying agronomic regimes facing diverse climate and soil conditions.

Main objectives:

1. Breed/establish multi-purpose quinoa varieties better adapted to saline, marginal Mediterranean soils, resilient to climate change, reducing post-harvest processing, and enriching crop diversity for sustainable agricultural management.

2. Establish zero-waste valorisation chains/nets for quinoa delivering affordable gluten-free food products and other non-foods.

3. Provide guidance, support and a networking platform for stakeholders.

 

HoLa Science – Hohenheim Lab for highschool students for STEM and agricultural research

 

HoLa Science Project

 Project start in October 2023


Motivation & Goals

- Early orientation and motivation of pupils in grades 8-12 for scientific work in natural and agricultural science or technical subject areas

- Demonstrating opportunities for professional development (training and/or studying) in STEM and agricultural subjects at the University of Hohenheim and getting pupils excited about technical connections and phenomena at an early stage

- Link current research with the school curriculum and underpin or expand it with practical experiments on socio-politically highly relevant issues

- Support the training of pupil‘s teachers and trainee teachers in a teaching-learning laboratory and at the same time use their didactic competence to expand the portfolio of the school laboratory (courses, summer camps, girls' day).

funded by:
PRIMA and Bundesministerium für Bildung  und Forschung for German partners

in progress since 2023


Brief description:

The PureCircles consortium has the following main objectives:

- Establish, test and validate the technical components of a recirculating system for integrated water and resources management IWRM system in Egypt, Tunisia, Morocco, Portugal and Spain.

- Maximize crop yield and resource efficiency (energy, water and nutrients) by complementing the hydroponic water rehabilitation system with customized water management plans for field crops in all study sites.

- Reducing water demand, optimizing salinity balance, and limiting sediment and pollutants in runoff water.

- AI-assisted irrigation and fertilization management tool.

- Installation and testing of agrophotovoltaics (e.g., flexible PV for greenhouses, agrovoltaics in fields) to evaluate their impact on crop yields and operational efficiency, and evaluation of the potential for dual-use PV panels to generate energy and captured rainwater (for groundwater recharge, salt leaching from soil, and irrigation) at study sites.

- Develop and test an AI-based decision and management tool that integrates the main components of the circular IWRM system with smart agriculture.

 

Ta’aziz Kurzmaßnahme - Ta'awon4Quinoa - Cooperation for Quinoa




gefördert vom DAAD aus Mitteln des Auswärtigen Amts (AA)

Travelling conference planned for Dec. 2023


The project "Ta'awon4Quinoa - Cooperation for Quinoa" aims to build networks and competences in the field of biodiversity of diversified agroecosystems, with a special focus on quinoa and other non-native "superfoods". For this purpose, (1) the existing partnerships with scientists from the Maghreb countries Tunisia, Algeria and Morocco are to be intensified, (2) expanded for the topic of biodiversity, and (3) new networks for future cooperation in Egypt are to be initiated.

In order to enable this exchange and knowledge building, we are planning a "Travelling Conference" as part of the Ta'ziz funding. The aim is for all those involved to know the different levels of biodiversity, to be able to use standardized procedures to record and then evaluate the context specifically for the respective locations.

The travelling conference is intended to nurture collaborations for a long-term exchange and future cooperation in order to prepare a thematically focused scientific partnership "Agrobiodiversity" between Germany and the transition countries Tunisia, Algeria, Morocco and Egypt. A participatory approach to solving current social challenges can be promoted and long-term added value can be generated in the sense of the UN Sustainable Development Goals (SDG).
