Thermography for soil salinity assessment

Abstract

data integration. Therefore, this chapter addresses question 2. The auxiliary line of research described in this chapter is the specificities of application on salt tolerant crops (quinoa). Chapter 4 is devoted to the validation of the thermography approach on regional scale and a robustness test, by applying the approach in several different locations of Australia where different crops are grown both in irrigated and rainfed conditions. This way research question 3 is addressed. Chapter 5 describes the validation on the global scale and issues of temporal development of the soil salinization problem. Comparison with several studies describing soil salinity change presented in the chapter together with global assessment of affected lands and its change in the period from 1986 to 2016. Chapter 6 synthesises the findings from all the chapters, puts them into a broader perspective and reflects on implications, methods and data used. Moreover, suggestions for further research are given. The general overview of the structure is given in Figure 1.3.
