Relationships of climate and irrigation factors with malaria parasite incidences in two climatically dissimilar regions in India

Abstract: We examine how climate and irrigation conditions are associated with malaria infection from 1986-1995 in two climatically dissimilar regions in India. We analyze annually averaged malaria parasite incidence (API) and seasonally averaged climate and irrigation variables in western Rajasthan and Arunachal Pradesh. In arid western Rajasthan, API is significantly positively correlated with summer precipitation and soil moisture, and negatively correlated with summer potential evapotranspiration. Irrigation variabl… Show more

“…During the months of March-April-May, a period of low precipitation, medium to higher temperature with lower relative humidity, there is an increase in the number of incidences of malaria. This also agrees with the findings of Lee et al [55], a study conducted in the humid Arunachal Pradesh, India, that suggests decreasing precipitation and increasing temperature resulted in increasing malaria incidence. With the arrival of the monsoon and during the June-July-August-September, the period of high to very high rainfall, higher temperature, and medium to high relative humidity, the malaria incidents were further on the rise.…”

“…However, feedbacks between irrigated agriculture and climate may compound trade-offs among several ecosystem services. Understanding irrigation-induced climate change is critical for informing stakeholder expectations and water management planning (Niles & Mueller, 2016), estimating growing season length and crop phenology (Zipper et al, 2016), forecasting crop disease and pest risks (Jones et al, 2017), and predicting chronic and infectious human disease risks (Kim et al, 2016;Lee et al, 2016). In this study, we use the Wisconsin Central Sands (WCS) as a representative region to quantify irrigation-induced changes to temperature and humidity in the Midwest United States and similar regions where irrigated agriculture is expanding.…”

“…Moreover, reductions in DTR and VPD can impact human health, specifically impacting vulnerable populations such as children and the elderly. For example, reductions in DTR can alleviate human respiratory and circulatory disease symptoms in children (Xie et al, 2017), reduce mortality in elderly populations (Kim et al, 2016), while increasing infectious and vector-borne disease risks in the general population (Lee et al, 2016). Thus, reductions in regional DTR and VPD could have far-reaching socioecological impacts.…”

“…Its level of endemicity and burden depends mainly on the environmental and ecological factors of the area affected [ 2 , 3 ]. Irrigated schemes provide a suitable environment for mosquito breeding and malaria transmission which needs special consideration in terms of malaria control and intervention selection [ 4 – 6 ]. Additionally, the risk of malaria endemicity is determined by many factors including the area of residence (urban or rural) and the level of interventions coverage [ 7 ].…”
