We analyze the decision to participate and performance at the Modern Olympic Summer Games at the country level. We use an unbalanced panel of 118 countries over all 24 editions of the Summer Games since 1896. The main focus of the paper is on economic, geographic and demographic determinants of Olympic participation and success. We estimate the impact of income per capita, population size, home...
Background: Ever increasing global population requires to find additional options or increase the efficiency of food and feed supply to fulfil its dietary needs. In agricultural sector, competing situations with energy supply occur and ask for more sustainable solutions in an ethically correct manner. Methods: The Sustainable Process Index (SPI) provides a powerful method for an ecological eval...
Rainfall is one of the most important climatic variables that determine spatial and temporal patterns climate variability a region, which provides useful information for planning agricultural production. For purpose crop planning, rainfall data two districts Tripura viz., Unakoti West aperiod 20 years (2001-2020) were collected used to analyze probability weekly rainfall. The incomplete Gamma d...
in recent years, in order to enhance the health of agroecosystems, concerns on ecological inputs especially to produce medicinal plants, has been increased. in order to evaluate the effects of winter cover crops on pgprs activities and soil nitrogen content in simultaneous application of organic manures and biological fertilizer in a low input production system of cucurbita pepo under minimum t...
Perennial biomass crops on marginal land improve both regional climate and agricultural productivity
Abstract Perennial grasses can reduce soil erosion, restore carbon stocks, and provide feedstocks for biofuels bioproducts. Here, we show an additional benefit, amelioration of regional climate warming, drying. Growing Miscanthus × giganteus , example perennial biomass crops, on US marginal land cools the Midwest Heartland summer by up to 1°C as predicted a new coupled climate‐crop modeling sys...
In intensively cropped agricultural landscapes, the vegetation in edges and hedges (henceforth “field margins”) represents an important semi-natural habitat providing fundamental resources for insect pollinators. We surveyed pollinating insects associated with two mass-flowering crops, apple oilseed rape, compared fauna of main crop that field margins grass-dominated landscapes Ireland. Differe...
The first significant processing of Terra MODIS data, called Collection 3, covered the period from November 2000 to December 2002. The Collection 3 leaf area index (LAI) and fraction vegetation absorbed photosynthetically active radiation (FPAR) products for broadleaf crops exhibited three anomalies (a) high LAI values during the peak growing season, (b) differences in LAI seasonality between t...
Seasonal Effects of Water Quality on Infant and Child Health in India This paper examines the impact of fertilizer agrichemicals in water on infant and child health using data on water quality combined with data on the health outcomes of infants and children from the 1992-93, 1998-99, and 2005-06 Demographic and Health Surveys of India. Because fertilizers are applied at specific times in the g...
Hybrid poplars have demonstrated high productivity as short rotation woody crops (SRWC) in the Midwest USA, and the hybrid aspen ―Crandon‖ (Populus alba L. × P. grandidenta Michx.) has exhibited particularly promising yields on marginal lands. However, a key obstacle for wider deployment is the lack of economic returns early in the rotation. Alleycropping has the potential to address this issue...
