ABSTRACT
Globally, in the process of agricultural development, the initial use of pesticides was an indispensable tool that improved food security by protecting economically important crops. Nevertheless, incessant and indiscriminate utilization of pesticides due to modern agricultural and healthcare practices contaminated the environment and has become a serious ecological and public health hazard due to their persistent nature, multifaceted toxicity, and recalcitrance, long-range environment transport potential, bioaccumulation, and biomagnification knack. To combat pesticide pollution in agricultural and non-agricultural settings, diverse techniques categorized as physical, chemical, physicochemical, biochemical, and biological remediation techniques have been employed worldwide either independently or in the alliance. Selection of effective remediation technique through proper screening method is crucial for restoration of pesticide-polluted environs. This chapter appraises global ecological and health hazards of pesticides, global scenario of pesticide production and usage, selection of remediation technique through screening approaches, global scenario of pesticide remediation techniques, indicators of sustainable remediation, and economics of global remediation sector. This chapter particularly summarizes the current global scenario of all the existing and emerging pesticide remediation techniques used to combat the menace of pesticide pollution hitherto. Moreover, this chapter focuses on knowledge gaps and future research directions for developing novel strategies for minimizing pesticide-related ecological problems.
