Conference Paper
Full-text available
The imperative for economic profitability causes agricultural intensification through conventional practices like monoculture, and synthetic agrochemicals increasing the carbon footprint and environmental degradation, exacerbating greenhouse gas emissions and environmental pollution. Organic farming (OF) offers sustainable alternatives, such as cro...
Conference Paper
Full-text available
Agricultural productivity is crucial for meeting the food demands of a growing global population, projected to reach 10 billion by 2050 [1]. However, conventional farming practices using chemical fertilizers have resulted in ecological imbalances, soil degradation, and threats to human health [2,3]. Farmers are increasingly turning to biofertilizer...
Conference Paper
Full-text available
Crops will increasingly have to undergo severe adaptation processes because climate change, which was once just a prediction, is now part of our daily lives. The process of maximizing production using less and less water is a line of research that is gaining scientific prominence and will certainly be one of the major solutions to food shortages in...

Climate—Madeira Strategy (CMS) foresees two models to describe the climate scenarios for the Madeira region in 2050 and 2070. These scenarios anticipate an average temperature rise of 1.4 to 3.7 °C and a decrease in precipitation by 30 to 40%. Consequently, Madeira’s agriculture will suffer the impacts of climate change. To understand these impacts...

Climate change does not happen in the distant future, but it is already present in our daily lives. The increase in temperature and decrease in precipitation volumes has gained prominence, making current and research work as a focus to overcome the constraints imposed by these two elements of the climate. The process of optimizing the use of water...

A agricultura na Madeira remonta ao início do povoamento. O trabalho abnegado dos agricultores, com mais de 600 anos, deu início a um processo de transformação do território, que permitiu o povoamento e a formação da agrodiversidade, com o desenvolvimento das suas várias componentes. A agricultura permitiu produzir o alimento, formar o território,...
Technical Report
O presente caderno de campo foi desenvolvido pelo ISOPlexis - Centro de Agricultura Sustentável e Tecnologia Alimentar da Universidade da Madeira, em parceria com a ACOESTE - Associação da Costa Oeste, com o intuito de auxiliar os agricultores na identificação dos recursos genéticos que têm nas suas explorações, ou dar a conhecer o património genét...

The use of neglected residues as a fertilizer into agro-systems intensifies the biosustainability and circular economy. In this line of thought, a research strategy was developed to test the potential of solar dehydrated sewage sludge (DSS), produced locally using residues of Porto Santo ETAR as amendment in sweet potato assays. Sewage sludge is a...

Common bean (Phaseolus vulgaris L.) is a staple food worldwide due to its nutritional value, with high protein and minerals content. Traditional agriculture is declining worldwide due to intensive agriculture, with loss of crop biodiversity and nutritional quality. The effect of location and weather events can also affect crop yield and quality, de...

Beta vulgaris L. subsp. maritima (L.) Arcang., sea beet, is a morphologically and genetically variable species, belonging to beet primary gene-pool. This crop wild relative is a valuable genetic resource for resistance improvement in beets and could play an important role in crop yield sustainability. Eleven Madeiran sea beet populations were chara...

Madeira Archipelago is a hotspot for crop wild relatives (CWR) of crop cultures. Some of these CWR are present in very specific environments, such as, in Ponta de São Lourenço or Desertas Islands. One such species is Beta patula Aiton, a Critically Endangered species which belongs to the Gene Pool 1b of cultivated beets. A continuous effort has bee...

Sweet potato (Ipomoea batatas (L.) Lam.) is an important staple food in several regions of the world. Water scarcity is the most devastating abiotic stress, with a great impact on crop productivity, food security, and subsistence. Drought restricts the nutrient intake and transport into the plant. Tolerant crops have morphological mechanisms of dro...
