BACKGROUND Owing to the emergence of some challenges in the demographic structure of many countries and possible decrease in young human workforce in the future decades, the reduction in the fertility rate has become a major public concern. This study aimed to investigate the effects of climatic factors on fertility. AIM In this correlational study conducted during 2005-2009, the relationship...

Water in the XXI century has become the primary factor for sustainable development, eradication of poverty and reversal of ecosystem degradation. Increasing water demand for agriculture and urbanisation, combined with pollution, eutrophication and amplification of the stochastic character of climatic processes, increases water limitations for ecosystems and societies. The transdisciplinary scie...

Investigating the Effect of Climate Indices on Number Beehives in Last Six Climatic Decades

The record drought of 2012 brought the issue of climatic vulnerability to the agricultural enterprise front and center. The swings in the temperature patterns associated with higher frost and freeze risks, as well as the midseason heat stress and heavy rain/severe weather risks have brought about potentially newer climatic regimens to light. Several associated shifts are apparent in regional gr...

Using outdoor public spaces as a place of social interaction is in a great consideration these days. Providing tolerable thermal condition as long as possible is one of the primary stage for people’s presence in these places. Outdoor thermal indices are introduced to help architects making appropriate decisions in climate responsive design procedure. By doing some field study research in extr...

isfahan province is located in the center of iran and has arid and semi-arid climate. in recent years, water shortage has increased in this region and has affected crop production. wheat is one of the most important crops of the province. in the present research, an index (dei) has been developed for drought evaluation using long term climatic data through application of principle components an...

The reliability of paleoclimatic inferences from lake-sediment records rests on the understanding of how various sediment indicators respond to environmental changes. Despite the recent proliferation of paleoclimatic records, only a limited number of studies have rigorously evaluated potential indicators by comparing lake-sediment records with instrumental weather data. We analyzed annually lam...
