Based on a bibliographic review, the article identifies and offers a critical analysis of scientific production by the public health field in Brazil on genetically modified organisms and food (in)security. Of the 716 articles found on the portals of the Scientific Electronic Library Online (SciELO) and the Coordinating Agency for the Development of Higher Education (Capes), only 8 address the f...

The FAO-56 Penman–Monteith (PM) equation is regarded as the most accurate to estimate reference evapotranspiration (ETo). However, it requires a broad range of data that may not be available or reasonable quality. In this study, nine temperature-based methods were assessed for ETo estimation during irrigation at fourteen locations distributed through hot-summer Mediterranean climate region Alen...

This paper examines and evaluates the integrated use of satellite remote sensing and meteorological data for estimating crop water requirements over agricultural areas of Cyprus. Intended purpose of this project is to estimate evapotranspiration using modeling techniques, satellite and meteorological data for monitoring irrigation demand. ETc was calculated with the FAO Penman-Monteith method b...

Accurate estimation of evapotranspiration plays a vital role in judicious irrigation scheduling. Keeping this view, study was undertaken to compare the performance five methods, viz. Penman method (PM), FAO Monteith (FAO-PM), Priestley-Taylor (PT), Radiation (FAO-RM) and Hargreaves methods (HM) for Sultanpur District Uttar Pradesh, India using daily weather data acquired from automatic station ...

Agricultural production is critical to meeting Indonesia's food demands. The water catchment area of Parit Keladi 1, located in Desa Keladi, Kecamatan Sungai Kakap, Kabupaten Kubu Raya, Provinsi Kalimantan Barat, includes tidal swamp land that has a variety plants. Cropwat 8.0 Software will be used this research assess crop needs. This employs primary and secondary data, including soil samples,...

Public opposition to genetically modified organisms (GMOs) remains strong. By contrast, studies demonstrate again and again that GM crops make a valuable contribution to the development of a sustainable type of agriculture. The discrepancy between public opinion and the scientific evidence requires an explanation. We argue that intuitive expectations about the world render the human mind vulner...
