The Sulfated Laminarin Triggers a Stress Transcriptome before Priming the SA- and ROS-Dependent Defenses during Grapevine's Induced Resistance agains…
2018
Grapevine (Vitis vinifera) is susceptible to many pathogens which cause significant losses to viticulture worldwide. Chemical control is available, but agro-ecological concerns have raised interest in alternative methods, especially in triggering plant immunity by elicitor treatments. The β-glucan laminarin (Lam) and its sulfated derivative (PS3) have been previously demonstrated to induce resistance in grapevine against downy mildew (Plasmopara viticola). However, if Lam elicits classical grapevine defenses such as oxidative burst, pathogenesis-related (PR)-proteins and phytoalexin production, PS3 triggered grapevine resistance via a poorly understood priming phenomenon. The aim of this st…
The Green Deal and the CAP: policy implications to adapt farming practices and to preserve the EU's natural resources
2020
The June 2018 CAP proposals are only marginally consistent with the ambitions of the Green Deal. This is also the case of the regulation revisions being adopted by either the Council or the European Parliament in October 2020. Making EU agriculture consistent with the Green Deal but would require a whole food chain policy that encompasses more stringent instruments on the supply side and extensive changes in eating patterns.
Agricultural Insurances and Food Security. The New Climate Change Challenges
2015
Abstract Food security is one of the highest problems that the governments have to face in the third millennium. The complexity of this problem justifies the performance of researches, in view of finding viable solutions, not only in agriculture, but in other branches of activity too. Among them, the field of insurances is to be noted by its struggles to adapt to the new challenges. This paper tries to clarify the way in which insurances may become a key factor for the food security and addresses the following issues: food security factors; factors impacting on the development of agricultural insurances, risks connected to the agricultural activities and the way in which the insurance prote…
Evaluación de los recursos naturales para un uso y gestión sostenible de la producción agraria en una cuenca del centro-sur de Córdoba (Argentina)
2001
The economical and social development in the Center-South of Cordoba, (Argentina) depends on the agriculture. However, due to low production and severe soil erosion, the farms are not longer economically feasible. This situation implies that the agriculture in the region might not be sustainable in the long run. This study assessed the potential production of the natural resources in the Santa Catalina basin, in order to improve their use and management. The estimated potential production is 300 % higher than the actual production. In addition, the basin is severely affected by water erosion. A new and more sustainable production structure was proposed for the basin, which increases from tr…
Landscape of Exception as Spatial and Social Interaction Between High-Quality Agricultural Production and Immigrant Labour Exploitation
2021
This Chapter analyses the spatial and social interaction phenomena between high-quality agricultural production and immigrant labour exploita- tion that produce the landscape of exception, a particular declination of the Agambenian (2005) “state of exception” concept. The landscape of exception construction mechanism is generated within South-Eastern Sicily through the productive system of greenhouses, finalised to the vegetables production. Green- houses, in particular, represent an effective tool for spatial manipulation over the landscape and social control of migrant workers. In relation to these considerations, this work reflects on ethical challenges and dilemmas of planning, highligh…
Mutations in Romanian Agriculture after De-Collectivization and Privatization
2013
Abstract This paper aims at presenting mutations in agriculture occurred in the process of collectivization and privatization of it. In this paper we analyze the period 1990-2010 following: the dynamics of the use of the land by ownership, the dynamic structure of the value of agricultural production, the dynamic structure of the value of agricultural production and development park tractors and machinery on-farm ownership. In the analyzed period is shown that mutations that occurred in the ownership of the land and other means of production and the system of relations between agriculture and other sectors of the economy have influenced the evolution of the structure of agricultural product…
Research of organic agricultural production support in Poland
2017
The features of supporting organic production in Poland are analyzed in the article. Poland is characterized by the largest employment of the population and the number of farms in the organic sector among the countries of Europe. Despite the favorable natural and climatic conditions, the scientific and practical base, significant areas occupied by organic production, the powerful export potential of the country, the proportion of organic operators in the structure of agricultural producers is very low. The main obstacles to the transition to organic principles are the poor development of environmental infrastructure and support from various services of the entire agricultural system. Theref…
Influence of arbuscular mycorrhizae on biomass production and nitrogen fixation of berseem clover plants subjected to water stress.
2014
Several studies, performed mainly in pots, have shown that arbuscular mycorrhizal symbiosis can mitigate the negative effects of water stress on plant growth. No information is available about the effects of arbuscular mycorrhizal symbiosis on berseem clover growth and nitrogen (N) fixation under conditions of water shortage. A field experiment was conducted in a hilly area of inner Sicily, Italy, to determine whether symbiosis with AM fungi can mitigate the detrimental effects of drought stress (which in the Mediterranean often occurs during the late period of the growing season) on forage yield and symbiotic N2 fixation of berseem clover. Soil was either left under water stress (i.e., rai…
Przestrzenne zmiany w strukturze produkcji rolnej w Unii Europejskiej
2016
Wiele zachodzących zjawisk, ich rozwój czy też kierunki zmian, uzależnione są od przestrzennych interakcji zachodzących pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share, który został wprowadzony do badań przez Nazarę i Hewingsa, przedstawia przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury towarowej produkcji rolnej w krajach Unii Europejskiej według wybranych rodzajów produktów rolnych z zastosowaniem przestrzennej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa zmian wielkości zjawiska oraz zidentyf…
Specjalizacja i konkurencyjność krajów UE w zakresie produkcji zbóż
2018
W artykule przedstawiono wyniki badań dotyczących specjalizacji i konkurencyjności produkcji roślinnej w krajach Unii Europejskiej. Do badań wykorzystano metodę zmiany konkurencyjności Estebana-Marquillasa. Metoda ta pozwoliła wskazać wyspecjalizowane kraje icharakter zmian strukturalnych w zakresie produkcji upraw. Badania przeprowadzono na podstawie danych dotyczących wielkości produkcji roślinnej. Wszystkie dane zostały zaczerpnięte z baz danych Głównego Urzędu Statystycznego. Badanie obejmuje lata 2005-2016. Uzyskane wyniki pozwalają na wyodrębnienie (nierozłącznych) grup krajów specjalizujących się w produkcji poszczególnych gatunków zbóż. W zakresie produkcji pszenicy specjalizują się…
