No till soil organic carbon sequestration could be overestimated when slope effect is not considered

2020

Abstract No tillage (NT) soil management has been considered a strategy for the implementation of environmental sustainability and a possible tool of soil organic carbon (SOC) sequestration. Considering the wide range of data on SOC change after NT application in relation to conventional tillage (CT) in different studies, further researches are needed over a diverse range of soil and climate before a proper estimation of the benefits can be provided by the NT. A data set composed of cereal cropping system studies, comparing the SOC content under CT and NT was compiled from the literature using the scientific repositories “Scopus” and “Science direct”. This aims to i) discriminate and quanti…

A review of soil carbon dynamics resulting from agricultural practices

2019

Abstract Literature related to the carbon cycle and climate contains contradictory results with regard to whether agricultural practices increase or mitigate emission of greenhouse gases (GHGs). One opinion is that anthropogenic activities have distinct carbon footprints – measured as total emissions of GHGs resulting from an activity, in this case, “agricultural operations”. In contrast, it is argued that agriculture potentially serves to mitigate GHGs emissions when the best management practices are implemented. We review the literature on agricultural carbon footprints in the context of agricultural practices including soil, water and nutrient management. It has been reported that the ma…

Long-term effects of contrasting tillage on soil organic carbon, nitrous oxide and ammonia emissions in a Mediterranean Vertisol under different crop…

2018

This 2-year study aimed to verify whether the continuous application of no tillage (NT) for over 20 years, in comparison with conventional tillage (CT), affects nitrous oxide (NO) and ammonia (NH) emissions from a Vertisol and, if so, whether such an effect varies with crop sequence (continuous wheat, WW and wheat after faba bean, FW). To shed light on the mechanisms involved in determining N-gas emissions, soil bulk density, water filled pore space (WFPS), some carbon (C) and nitrogen (N) pools, denitrifying enzyme activity (DEA), and nitrous oxide reductase gene abundance (nosZ gene) were also assessed at 0–15 and 15–30 cm soil depth. Tillage system had no significant effect on total NH e…

Ethique professionnelle et régulation économique du marché des soins ambulatoires : de la théorie des contrats à l'économie des conventions

1992

What is the part played by professionnal ethics in the economic regulation of the market for ambulatory care (heterogeneity, uncertainty, information asymmetry...) and extrinsic rigidities (imposed by medical corporation and public authorities) ? Is it the internal control variable from "interested" self-regulation that implicitly relies on teological conception of ethics ? Or, the essential being of conventions for "quality" and "activity" that, through the cycle of gift economics, set upspontaneous order, with respect to professional ethics ? What usecan we do with such theoritical approach for the understanding andthe trend of politics in ambulatory care ?

In tema di proprietà: il modello romano nella tradizione giuridica

2021

We are back to discuss ownership. In fact, beyond all possible predictions, the history of property law is combined with that of fundamental human rights. The individual perspective of absoluteness, present in the codicistic tradition, the predominantly economic content of the property right, governed by the Constitution, are today deeply intertwined with the perspective of the protection and enhancement of the subject who owns it, in accordance with the provisions of the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR) and the Charter of Fundamental Rights of the European Union (Charter of Nice). . This new perspective of protection is associated with …

Management of Cultural Landscapes: What Does this Mean in the Former Soviet Union? A Case Study from Latvia

2009

Concern about changing cultural landscapes has increased recently, with the advent of the European Landscape Convention placing signatory countries in a position of having to develop action for protecting and managing cultural landscapes. In countries of the former Soviet Union the landscape underwent many changes as a result of agricultural collectivisation and its aftermath. This situation has been analysed for six sample rural municipalities (pagasts) in Latvia, one of the three former Soviet countries to join the European Union (EU), using maps from the period 1901 to 1927 (to represent the ‘traditional landscape’) and 1997 orthophotographs updated to 2000 (to represent the ‘post-Soviet…

Challenges in EU External Climate Change Policy-Making in the Early Post-Lisbon Era: The UNFCCC Copenhagen Negotiations

2011

The 15th United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP) meeting held in Copenhagen from 7 to 18 December 2009, which took place one week after the entry into force of the Treaty of Lisbon on 1 December 2009, has brought about rather disappointing outcomes from the perspective of the European Union (EU), which had previously displayed substantial leadership within the UN climate regime. Contrary to the EU’s objectives for the COP15 meeting, no legally binding agreement was reached to succeed the Kyoto Protocol after 2012 and the final Copenhagen Accord contained disappointingly few ambitious targets. This chapter tries to explain how this resul…

Bezpieczeństwo granic Unii Europejskiej w kontekście kryzysu migracyjnego 2015/2016

2016

The European Union is a space within which the freedom of movement of citizens, expressed through freedom to travel. work, study or live in a chosen EU country, is realized. The implementation of this freedom was a result of the abolition of Controls at internal borders of the Union. However. for a Member of the EU, the price of this freedom is the necessity to ensure national security, which makes the protection of external borders a special task. The European Union, through the Schengen Agreement, created institutions for the protection of external borders in terms of ensuring the national security of Member States, The current migration crisis is a serious verification of the effectivene…

Instytucja granic zewnętrznych Unii Europejskiej a zapewnienie bezpieczeństwa państw członkowskich w warunkach współczesnego kryzysu migracyjnego

2017

Unia Europejska to przestrzeń w obrębie której realizowana jest swoboda przemieszczania się obywateli. Realizacja tej swobody nastąpiła w wyniku zniesienia kontroli na wewnętrznych granicach Unii. Jednak dla państwa unijnego ceną tej wolności jest zapewnienie bezpieczeństwa narodowego co czyni szczególnym ochronę granic zewnętrznych. Unia Europejska, głównie poprzez Układ z Schengen stworzyła instytucje dla ochrony granic zewnętrznych pod kątem zapewnienia bezpieczeństwa narodowego państw członkowskich i ich obywateli. Obecny kryzys migracyjny stanowi poważną weryfikację dla oceny skuteczności działania tych instytucji. Celem niniejszego artykułu jest analiza problemu funkcjonowania zewnętr…
