“…1b) contents. It was shown that NaCl and Cd bring ionic toxicity by elevated levels of Na + [28][29][30] and Cd 2+ [32][33] in plant tissues, which disturbs nutrient uptake and stomatal opening, inhibits some of the enzymes of the Calvin cycle, and affects plant biomass [62].…”

“…This concept is based on the assumption that vegetation coverage mitigates high LST occurrence values. The relationship between thermal characteristics of surface and vegetation indices has been extensively documented in the literature [7,13,[48][49][50][51][52]. Many studies have observed a negative relationship between LST and vegetation indices.…”

For a reliable assessment of sustainability in big cities, it is imperative to evaluate urban ecosystem conditions and the environment of the cities undergoing economic growth. Urban green spaces are valuable sources of evapotranspiration, which is generated by trees and vegetation; these spaces mitigate urban heat islands in cities. Land surface temperature (LST) is closely related to the distribution of land-use and land-cover characteristics and can be used as an indicator of urban environment conditions and development. This study evaluates the patterns of LST distribution through time by employing the thermal spatial distribution signature procedure using thermal infrared data obtained from Landsat-5 Thematic Mapper. A set of 18 images, between 1985 and 2010, OPEN ACCESSSustainability 2015, 7 3130 was used to study the urban environment during summer in 47 neighborhoods of Porto Alegre, Brazil. On a neighborhood scale, results show a non-linear inverse correlation (R² = 0.55) between vegetation index and LST. The overall average of the LST is 300.23 K (27.8 C) with a standard deviation of 1.25 K and the maximum average difference of 2.83 K between neighborhoods. Results show that the Thermal Spatial Distribution Signature (TSDS) analysis can help multi-temporal studies for the evaluation of UHI through time.

“…All these changes disturb the normal process of photosynthesis, leading towards less production of photosynthates and ultimately poor yield (Mondal, Khajuria, 2000). Drought stress also decreases the activity of Rubisco (Silva et al, 2012). Under drought stress 2-carboxyarabinitol-phosphate is formed in many plants which binds strongly with Rubisco and restricts its catalytic activity (Parry et al, 2002).…”

Oilseed rape (Brassica napus L.) is an important oilseed crop worldwide. Drought is the most detrimental environmental factor affecting the crop plants from germination up to maturity. A complete perspective of the effect of drought is crucial in understanding the influence of climate variability on rape cultivation. Water deficit stress affects morphology, physiology and development of rape crop. The aim of this article is to present an outline of the effects of drought stress on the growth, physiological processes, yield and quality parameters of rape crop. When drought stress occurs at critical stages, both short and long term, it can adversely affect important growth and physiological processes like leaf area, root growth, shoot growth, excised leaf water loss (ELWL), relative water content (RWC), photosynthesis and water use efficiency (WUE) by disturbing stomatal adjustment, producing reactive oxygen species (ROS), lowering stomatal conductance and destroying the chlorophyll and other pigments. Rape is more susceptible to water deficit stress during reproductive stages which ultimately affect the yield and oil quality. Some important management strategies for drought mitigation in rape, including use of compatible solutes, nutrients, plant growth regulators, different planting methods are also mentioned and discussed in this review paper.
