Ever since the beginning of international climate conservation politics there has been variation across nations in political traditions in debating the climate issue. Political decision-makers have interpreted the scientific findings on global warming with different emphases, thereby giving rise to variation in views on preferred national or international solutions. These tensions first became evident before and during the Earth Summit of the United Nations in 1992 in Rio de Janeiro, when the United Nations Climate Change Convention was prepared and eventually signed. This article discusses the historical background of international climate conservation politics and illustrates the tensions…

Which has more influence on perception of pseudo-therapies: the media’s information, friends or acquaintances opinion, or educational background?

2019

This study analyses the discourses of Education and Journalism students in order to understand their perception of complementary and alternative therapies. Likewise, to know if educational background or friends or acquaintances opinion has a more considerable influence on their knowledge and use of these socially controversial techniques than the media. This study uses qualitative research methods based upon 12 discussion groups with 102 participants. Once transcriptions were completed, discourse analysis was conducted using linguistic corpus software (T-LAB. 9.1.). In the design of the research, these students were selected for their social involvement in their future careers, such as when…

Long-term effects of contrasting tillage systems on soil C and N pools and on main microbial groups differ by crop sequence

2021

Abstract Determining the best conservation agriculture practices for increasing soil organic carbon (C) and hence soil quality is of paramount importance in the semi-arid Mediterranean environment, where soils are experiencing a continuous decline in organic matter. Therefore, the aim of this long-term study was to assess the combined effects of tillage system and crop sequence on soil organic C and biochemical properties of soil generally used as indicators of soil quality. After 23 years of continuous application of contrasting tillage systems (conventional tillage [CT], vs. no tillage [NT]) and crop sequences (wheat monoculture vs. wheat-faba bean rotation), soil samples were collected f…

Long-term effects of soil management on ecosystem services and soil loss estimation in olive grove top soils

2016

Soil management has important effects on soil properties, runoff, soil losses and soil quality. Traditional olive grove (OG) management is based on reduced tree density, canopy size shaped by pruning and weed control by ploughing. In addition, over the last several decades, herbicide use has been introduced into conventional OG management. These management strategies cause the soil surface to be almost bare and subsequently high erosion rates take place. To avoid these high erosion rates several soil management strategies can be applied. In this study, three strategies were assessed in OG with conventional tillage in three plots of 1. ha each. Soil properties were measured and soil erosion …

Soil Quality as Affected by Intensive Versus Conservative Agricultural Managements

2017

Soils, the earth’s skin, are at the intersection of the lithosphere, hydrosphere, atmosphere, and biosphere. The persistence of life on our planet depends on the maintenance of soils as they constitute the biological engines of earth. Human population has increased exponentially in recent decades, along with the demand for food, materials, and energy, which have caused a shift from low-yield and subsistence agriculture to a more productive, high-cost, and intensive agriculture. However, soils are very fragile ecosystems and require centuries for their development, thus within the human timescale they are not renewable resources. Modern and intensive agriculture implies serious concern about…

Cover Crop Impact on Soil Organic Carbon, Nitrogen Dynamics and Microbial Diversity in a Mediterranean Semiarid Vineyard

2020

Cover crop (CC) management in vineyards increases sustainability by improving soil chemical and biological fertility, but knowledge on its effects in semiarid soils is lacking. This study evaluated the effect of leguminous CC management on soil organic carbon (SOC) sequestration, soil nitrate content and microbial diversity in a semiarid vineyard, in comparison to conventional tillage (CT). SOC and nitrate were monitored during vine-growing season

Nitrogen losses in vineyards under different types of soil groundcover. A field runoff simulator approach in central Spain

2017

The soils of Mediterranean vineyards are usually managed with continuous tillage, resulting in bare soil, low infiltration and high soil erosion rates. Soil nutrients, such as nitrogen, could be lost dissolved in the runoff, causing a decrease in soil fertility on such degraded soils and producing eutrophication downstream. The influences of groundcover on the soil erosion processes and sediment yields in Mediterranean vineyards have been widely addressed. However, the runoff process itself, excluding the effect of raindrop impacts, has barely been studied. Thus, a field runoff simulator was built to assess runoff and nutrient losses under different soil management strategies in Central Spa…

Bacterial growth and biological properties of Cymbopogon schoenanthus and Ziziphus lotus are modulated by extraction conditions

2020

Abstract The present study aims to evaluate the antibacterial activity and biological properties of two traditional Saharian plants (Cymbopogon schoenanthus and Ziziphus lotus). The plant extracts were obtained by using a different combination of extraction methods (conventional vs. ultrasound-assisted) and solvents (water vs. ethanol:water (50:50, v/v)). The antioxidant profile, anti-inflammatory activity and impact on bacterial growth (foodborne and probiotic bacteria) of the obtained extracts were assessed. The plant species showed the hierarchically more important role in determining the biological properties of the extracts, followed by extraction solvent and extraction conditions. Con…
