Agricultural land abandonment is an emerging problem in European Union (EU), and about 11% of agricultural EU at high risk the coming 10 years. Land may have both positive negative effects ecosystems. Due to potential for increase soil fertility, study vegetation succession on quality great importance. In this study, we investigated abandoned vineyard where, after a period 30 years, rows alleys...

there are many reports of serious problems of dust storm events in the western parts of iran. based on many researches, iraq is one of the main sources of dust storms in western parts of iran. the radial basis function network (rbfn) model has been used to assess wind erosion hazard in iraq as a main source area of dust storms over several western cities of iran. the percentage of vegetation is...

given the critical role played by urban green spaces and the emergence of remote sensing as avaluable natural resource management tool, this study sought to identify trends in green spaces within thecontext of south africa’s transition period (1990 - 2000). using the city of port elizabeth as a case study, threesets of landsat - 5 thematic mapper images (1990, 1995 and 2000) were geo-processed,...

Background and Aim: Iran has experienced a great variation in women's status in recent years. There is a little knowledge on how and why advancing gender equality and equity and the empowerment of women play a role in recent fertility reduction in the country. This study was conducted to gain insight into the role of gender beliefs and women's empowerment in the couples 'experiences of fertilit...

The objective of this work was to determine the suitability poultry methacompost from 2nd methanizer BRIN FOUNDATION in Yaokokoroko (Bondoukou, Côte d’Ivoire), be used improvement soil fertility. studied has a C/N ratio = 17.26, which could characterize stable with high amending power. It also contains mineral elements Nitrogen (N) 0.68% DM; Phosphorus (P) 0.084% Potassium (K) 0.67% Calcium (Ca...

Abstract. Although the generally high fertility of volcanic soils is often seen as an opportunity, short-term consequences eruptions on natural and cultivated vegetation are likely to be negative. The empirical knowledge obtained from post-event impact assessments provides crucial insights into range parameters controlling recovery vegetation, but their limited coverage in time space offers a s...

Plants acquire carbon through photosynthesis to sustain biomass production, autotrophic respiration and production of non-structural compounds for multiple purposes1. The fraction of photosynthetic production used for biomass production, the biomass production e ciency2, is a key determinant of the conversion of solar energy to biomass. In forest ecosystems, biomass production e ciency was sugg...
