This short chapter is a comment on the chapter titled "Significance of the Silent Revolution of intensive groundwater use in world water policy", by M.R. Llamas & P. Martínez-Santos (this volume). The main argument of Llamas & Martínez-Santos is that intensive use of groundwater offers an important window of opportunity for solving the so called world water crisis. In response to this, my comment is divided into three parts. In the first section, I try to ascertain the magnitude as well as the causes of water crisis in the world. In doing so, I particularly look at water poverty of nations. In the second section, I critically analyze the postulates of Llamas & Martínez-Santos and comment on how viable their recommendation of mitigating water crisis or meeting Millennium Development Goals (MDG) with intensive groundwater use is likely to be. In the third, and the final section, I present some of my thoughts on groundwater governance, which I believe will be vital, if groundwater is ever poised to tackle world's water problems.
