Heat waves have a drastic impact on urban populations, which could increase with climate change. The authors evaluated new indicators of elderly people’s exposure to heat in Paris, from a public health prevention perspective, using satellite thermal images.

We assessed a donor-funded grassland management project designed to create both conservation and livelihood benefits in the rangelands of Mongolia's Gobi desert. The project ran from 1995 to 2006, and we used remote sensing Normalized Differential Vegetation Index data from 1982 to 2009 to compare project grazing sites to matched control sites before and after the project's implementation.

An important source of uncertainty in anticipating the effects of climate change on agriculture is limited understanding of crop responses to extremely high temperatures. This uncertainty partly reflects the relative lack of observations of crop behaviour in farmers’ fields under extreme heat. We used nine years of satellite measurements of wheat growth in northern India to monitor rates of wheat senescence following exposure to temperatures greater than 34 °C.

Heavy rains on 18 and 19 September 2010 in the Ganga watershed associated with a regional monsoon event that occurred between Myanmar and Middle East caused disastrous landslips in Uttarakhand, Indian Central Himalaya and floods in the plains of Punjab, Uttar Pradesh and Delhi. Relation between quantum of rainfall per day and slope failure has been examined in the light of similar studies in other parts of Himalaya. The cloud movement and rainfall pattern

Recent clusters of outbreaks of mosquito-borne diseases (Rift Valley fever and chikungunya) in Africa and parts of the Indian Ocean islands illustrate how interannual climate variability influences the changing risk patterns of disease outbreaks. Although Rift Valley fever outbreaks have been known to follow periods of above-normal rainfall, the timing of the outbreak events has largely been unknown. Similarly, there is inadequate knowledge on climate drivers of chikungunya outbreaks.

For long we have been fed lies. Mumbai has no scarcity of houses and the key to the truth lies in using digital technology to unlock the city's housing potential.
