The onset of the rainy season and farmers’ sowing strategy for pearl millet cultivation in Southwest Niger
2011
A multi-year (2004-2009) field survey of on-farm sowing practices in 10 villages located in south-west Niger close to Niamey, is analysed to investigate the relationships (i) between rainfall and the sowing date of pearl millet and the risk of sowing failure, (ii) between sowing and meteorological/agro-climatic onset dates, (iii) between sowing/onset dates, and simulated and observed yield/biomass at the end of the season. Even if some villages sow without any synchronous or anterior rainfall, most parcels (73% out of the 1551 available cases) are sown during and just after a 2-day wet spell receiving at least 10 mm. In fact, there is a strong correlation (r = 0.82-0.95 depending on onset d…
Estimating energy balance fluxes above a boreal forest from radiometric temperature observations
2009
Abstract The great areal extent of boreal forests confers these ecosystems potential to impact on the global surface-atmosphere energy exchange. A modelling approach, based on a simplified two-source energy balance model, was proposed to estimate energy balance fluxes above boreal forests using thermal infrared measurements. Half-hourly data from the Solar-Induced Fluorescence Experiment, carried out in a Finnish boreal forest, was used to evaluate the performance of the model. Energy balance closure, determined by linear regression, found all fluxes to underestimate available energy by 9% (r2 = 0.94). Significance in the energy balance of the heat storage in the air and in the soil terms w…
Research on ecological design to enhance comfort in open spaces of a city (Valencia, Spain). Utility of the physiological equivalent temperature (PET)
2013
For many years now, research has focused on issues concerning making cities easier to live in and some of the most important of these concern climatology and thermal comfort issues. There is also a growing awareness of the importance of open spaces and green areas, as key elements in providing opportunities for human interaction, leisure and physical exercise. They are important for all inhabitants, but particularly so for children and the elderly population. Of especial interest are the studies which have examined the interaction of comfort with the urban climate. This issue was studied throughout the twentieth century, but recently the role which can be played by biometeorological indices…
Overheating adaptations in acclimatised Singaporeans: Do spatial adaptation options matter? A pilot study Tanjong Pagar CBD case study
2022
Climate responsive design aims to mitigate extreme heat by consciously integrating climate principles inurban architectures and developments. Thereby, the adoption of climate-responsive design in urbanareas is foreseen to increase the adaptation capacities of urban dwellers to overheating. However,behavioural overheating adaptation can also be aspatial (e.g. a change in activity program, clothes, orfood regime), and thus not depend on the quality of outdoor spaces. According to the behaviouralplanned theory, the selection of one of these is determined by the individual knowledge of heatadaptation options, its transaction capacities with its daily routines, and cultural beliefs giving itscom…
