RESUMO

Future trajectories of agricultural productivity need to incorporate environmental targets, including the reduction of pesticides use. Landscape features supporting natural pest control (LF-NPC) offer a nature-based solution that can serve as a partial substitute for synthetic pesticides, thereby supporting future productivity levels. Here, we introduce a novel approach to quantify the contribution of LF-NPC to agricultural yields and its associated economic value to crop production in a broad-scale context. Using the European Union as case study, we combine granular farm-level data, a spatially explicit map of LF-NPC potential, and a regional agro-economic supply and market model. The results reveal that farms located in areas characterized by higher LF-NPC potential experience lower productivity losses in a context of reduced synthetic pesticides use. Our analysis suggests that LF-NPC reduces yield gaps on average by four percentage points, and increases income by a similar magnitude. These results highlight the significance of LF-NPC for agricultural production and income, and provide a valuable reference point for farmers and policymakers aiming to successfully invest in landscape features to achieve pesticides reduction targets.

RESUMO

Recent studies have estimated the potential yield impacts of pesticide reductions in the European Union. While these estimates guide policy design, they are often based on worst-case assumptions and rarely account for positive ecological feedbacks that would contribute to sustainable crop yields in the long term.

RESUMO

Significant shares of harvests are lost to pests and diseases, therefore, minimizing these losses could solve part of the supply constraints to feed the world. Cisgenesis is defined as the insertion of genetic material into a recipient organism from a donor that is sexually compatible. Here, we review (i) conventional plant breeding, (ii) cisgenesis, (iii) current pesticide-based disease management, (iv) potential economic implications of cultivating cisgenic crops with durable disease resistances, and (v) potential environmental implications of cultivating such crops; focusing mostly on potatoes, but also apples, with resistances to Phytophthora infestans and Venturia inaequalis, respectively. Adopting cisgenic varieties could provide benefits to farmers and to the environment through lower pesticide use, thus contributing to the European Green Deal target.

RESUMO

BACKGROUND: In 2013, the European Commission restricted the use of three neonicotinoids (clothianidin, imidacloprid and thiamethoxam) and the pyrazole fipronil, which are widely used to control early-season pests. Here, we used original farm survey data to examine the impact of the restrictions on pest management practices in eight regional case studies including maize, oilseed rape and sunflower in seven European Union (EU) countries. RESULTS: In four case studies, farmers switched to using untreated seeds as no alternative seed treatments were available. In three case studies, farmers switched to using unrestricted neonicotinoid- or pyrethroid-treated seeds. In five case studies, farmers increased the use of soil or foliar treatments, with pyrethroids as the principal insecticide class. Other changes in pest management practices ranged from increased sowing density to more frequent scouting for pests. Many farmers perceived that the time, cost and amount of insecticides required to protect crops increased, along with pest pressure. Alternative seed treatments were mostly perceived as being less effective than the restricted seed treatments. CONCLUSION: Farmers generally relied on alternative seed treatments or more soil/foliar treatments in the first growing season after the restrictions took effect. Further study is required to assess the effectiveness and sustainability of these alternatives compared with the restricted insecticides. © 2017 The Authors.

RESUMO

This article aims to inform the reader of the importance of searching patent landscapes in plant biotechnology and the use of basic tools to perform a patent search. The recommendations for a patent search strategy are illustrated with the specific example of zinc finger nuclease technology for genetic engineering in plants. Within this scope, we provide a general introduction to searching using two online and free-access patent databases esp@cenet and PatentScope. The essential features of the two databases, and their functionality is described, together with short descriptions to enable the reader to understand patents, searching, their content, patent families, and their territorial scope. We mostly stress the value of patent searching for mining scientific, rather than legal information. Search methods through the use of keywords and patent codes are elucidated together with suggestions about how to search with or combine codes with keywords and we also comment on limitations of each method. We stress the importance of patent literature to complement more mainstream scientific literature, and the relative complexities and difficulties in searching patents compared to the latter. A parallel online resource where we describe detailed search exercises is available through reference for those intending further exploration. In essence this is aimed at a novice patent searcher who may want to examine accessory patent literature to complement knowledge gained from mainstream journal resources.

RESUMO

In 2007, a genetically modified herbicide tolerant (GMHT) sugar beet (Beta vulgaris L.) tolerant against glyphosate, a commonly used broad spectrum herbicide, was commercialised in the USA and Canada. The speed of uptake of GMHT sugar beet by farmers has no precedent. While it took the hitherto most successful GM crop in the USA 15 years to reach an adoption rate of 95%, GMHT sugar beet achieved this figure after only 2 years. This paper traces the history of GMHT sugar beet which started at the European continent and describes the economic and environmental impact of its introduction in the USA. The results suggest that the rapid adoption is economically sound with adopter rents averaging $257/ha. Moreover the adoption has a high potential to reduce the environmental impact of sugar beet production. Will these experiences bring GMHT sugar beet back to its roots in Europe?

RESUMO

This article analyses European Union (EU) farmers' attitudes towards adoption of genetically modified crops by identifying and classifying groups of farmers. Cluster analysis provided two groups of farmers allowing us to classify farmers into potential adopters or rejecters of genetically modified herbicide-tolerant (GMHT) crops. Results showed that economic issues such as the guarantee of a higher income and the reduction of weed control costs are the most encouraging reasons for potential adopters and rejecters of GMHT crops. This article also examines how putting in place measures to ensure coexistence between GM and non-GM crops may influence farmers' attitudes towards GMHT crop adoption. Results show that the implementation of a coexistence policy would have a negative impact on farmers' attitudes on adoption and consequently may hamper GMHT adoption in the EU.

RESUMO

Production of foreign molecules in transgenic plants is anticipated to be an alternative to already established, microbial or animal expression systems with lower production costs. This article reviews the different technologies and approaches currently used to produce economically interesting molecules in plants or plant cell cultures, to evaluate their technical feasibility and economic implications, and to assess the potential socioeconomic and environmental impacts deriving from the adoption of molecular farming products.

RESUMO

The complete nucleotide (nt) sequences of genomic RNAs 1 and 2 of Cucurbit yellow stunting disorder virus (CYSDV) were determined for the Spanish isolate CYSDV-AlLM. RNA1 is 9123 nt long and contains at least five open reading frames (ORFs). Computer-assisted analyses identified papain-like protease, methyltransferase, RNA helicase and RNA-dependent RNA polymerase domains in the first two ORFs of RNA1. This is the first study on the sequences of RNA1 from CYSDV. RNA2 is 7976 nt long and contains the hallmark gene array of the family Closteroviridae, characterized by ORFs encoding a heat shock protein 70 homologue, a 59 kDa protein, the major coat protein and a divergent copy of the coat protein. This genome organization resembles that of Sweet potato chlorotic stunt virus (SPCSV), Cucumber yellows virus (CuYV) and Lettuce infectious yellows virus (LIYV), the other three criniviruses sequenced completely to date. However, several differences were observed. The most striking novel features of CYSDV compared to SPCSV, CuYV and LIYV are a unique gene arrangement in the 3'-terminal region of RNA1, the identification in this region of an ORF potentially encoding a protein which has no homologues in any databases, and the prediction of an unusually long 5' non-coding region in RNA2. Additionally, the CYSDV genome resembles that of SPCSV in having very similar 3' regions in RNAs 1 and 2, although for CYSDV similarity in primary structures did not result in predictions of equivalent secondary structures. Overall, these data reinforce the view that the genus Crinivirus contains considerable genetic variation. Additionally, several subgenomic RNAs (sgRNAs) were detected in CYSDV-infected plants, suggesting that generation of sgRNAs is a strategy used by CYSDV for the expression of internal ORFs.
