“…Recent studies have proposed FUs that address the delivery of different functions (type III). For example, a multi-product approach has been proposed by Röös et al (2016) and Costa et al (2018). Costa et al (2018) propose a FU based on a population demand for five food and energy products over a period of 7 years.…”

Costa et al (2018) propose a FU based on a population demand for five food and energy products over a period of 7 years. This approach enables agricultural systems and rotations producing a range of different products to be compared in terms of their delivery of a proportion of overall human consumption.…”

“…The choice of impact categories varies among the studies, and global warming potential is by far the most adopted impact category across all studies, which neglects potentially important co-benefits and trade-offs. For example, Costa et al (2018) showed that complex crop-animal-tree rotation systems had a lower global warming potential but very high abiotic depletion (due to more use of animal feed compounds) compared with conventional (separate) systems. Regarding the calculators and tools designed to address LCA cropping system interactions, the Crop.LCA tool (Goglio et al 2018b) is the only one that provides acidification potential, eutrophication and energy demand alongside global warming potential.…”

Purpose There is an imperative to accurately assess the environmental sustainability of crop system interventions in the context of food security and climate change. Previous studies have indicated that the incorporation of legumes into cereal rotations could reduce overall environmental burdens from cropping systems. However, most life cycle assessment (LCA) studies focus on individual crops and miss environmental consequences of inter-annual crop sequence and nutrient cycling effects. This review investigates state-of-the-art representation of inter-crop rotation effects within legume LCA studies. Methods A literature review was undertaken, starting with a search for all peer-reviewed articles with combinations of ‘LCA’, ‘legumes’ and ‘rotations’ or synonyms thereof. In total, 3180 articles were obtained. Articles were screened for compliance with all of the following requirements: (i) reporting results based on LCA or life cycle inventory methodology; (ii) inclusion of (a) legume(s); (iii) the legume(s) is/are analysed within the context of a wider cropping system (i.e. rotation or intercropping). Seventy articles satisfying these requirements were analysed. Results and discussion We identified three broad approaches to legume LCA. Most studies involved simple attributional LCA disregarding important interactions across years and crops in rotations. N-fertilizer reduction through legume residue N carryover is either disregarded or the benefit is attributed to the following crop in such studies, whilst N leaching burdens from residues are usually attributed to the legume crop. Some studies applied robust allocation approaches and/or complex functional units to enable analysis of entire rotation sequences, accounting for nutrient cycling and break crop effects. Finally, a few studies applied consequential LCA to identify downstream substitution effects, though these studies did not simultaneously account for agronomic effects of rotational sequence changes. Conclusions We recommend that LCA studies for legume cropping systems should (i) evaluate entire rotations; (ii) represent nitrogen and ideally carbon cycling; (iii) for attributional studies, define at least two functional units, where one should encompass the multifunctional outputs of an entire rotation and the other should enable product footprints to be calculated; (iv) for CLCA studies, account for both agronomic changes in rotations and markets effects; (v) include impact categories that reflect hotspots for agricultural production.

“…(Andrade, 2011, p.122) Portanto o estudo pesquisado enquadra-se nos tipos de pesquisas já mencionadas. Assim, novas técnicas e conceitos têm emergido, como a integração lavourapecuária-floresta em áreas produtivas tradicionais do cerrado brasileiro, as quais aumentam a complexidade da gestão agropecuária (COSTA et al, 2018, MARQUES et al, 2020. Ainda na mesma linha, a agricultura urbana e periurbana, nas quais a produção de alimentos apresenta um potencial para a redução de impactos relacionados à logística, além de promover a soberania alimentar (DE NADAI et al, 2019) Diante das mudanças no setor, a capacidade para desenvolver e adequar as atividades setoriais coincidem com o anseio por uma produção integrada e dinâmica, Assim sendo, o modelo de produção agropecuária convencional e baseado no uso intensivo de insumos químicos, biotecnológicos e aparatos mecanizados, tem sido disseminado em universidades públicas e privadas (PINTO, 2014), refletindo-se no ensino técnico conforme é observado por Soares (2001).…”

“…Integrated systems can combine crop production, livestock, and forestry, supporting the production of at least three types of product from the same land area over a defined period These systems, based on intercropping, succession, and/or rotation, can optimize the biological cycling of nutrients between plants and animals, improving production efficiency and maintaining long-term soil fertility, considering they are also organic methods. For example, an integrated system includes tropical forage plants, which replenish soil organic matter, recycle nutrients underground, and contribute to biological plowing and microbial activity due to their extensive root systems [44].…”

Textile natural fibers production regarding the agroforestry approach

et al. 2019

View full text Add to dashboard Cite

As sustainability is becoming an important topic for both agriculture and the textile sector, there is an increasing market demand for plant-based fibers production. Diversified farming systems, such as agroforestry, have received considerable attention for their potential to contribute to more environmentally sustainable and socially just agricultural methods, that offers a smart use of water and soil nutrition. They can be a direction for rural development through contributions in agrobiodiversity, livelihood diversity, labor availability and economic growth. They are currently being promoted in many regions to contribute for food security, climate change adaptation and mitigation. In this study, the research methodology was based on a systematic literature review and secondary data collection and analyses. The aim was to investigate initiatives towards sustainable textile fibers cropping, including different species and plantation methods. The results indicate few cases worldwide and suggest cotton as the main experimented specie, generally cultivated with two other ones. They were identify three methods applied in cotton crops: (1) crop rotation, (2) agroecological intercropping and (3) agroforestry. Results also demonstrates different production challenges, concerning machinery development to mixture crops, ideal species groups, economic viability and process scalability. Forest management methods that can sustain good mixes of tree species need to be designed, promoting rich agrobiodiversity landscapes. Thus, defining, measuring and rewarding good farming practices are the main possible drivers to motivate farmers to change to new approaches towards sustainability in textile fiber production. Further investigation is demanded to evaluate different species possibilities and cropping maintenance, as well as addressing public policies and coordinating stakeholders interests.
