It’s late afternoon and I am sitting on the veranda at my parent’s house in the small mountain town of Montagu in the Western Cape Province of South Africa. In front of me lies a fishpond, inhabited mostly by Koi, and beyond that stretches a green lawn scattered with a variety of fruit trees. Some overripe apples have fallen to the ground, enticing several of the plump hens who have free range in the garden. To my left is a large vegetable patch and the chicken coop where my mother collects fresh eggs every morning. Grapevines creep up and over the latticework above my head, creating a dappled shade, and hummingbirds flit around the birdfeeders that have been hung from the pillars (read more).

Groundwater is among the world’s most important natural resources. It provides drinking water to rural and urban communities, supports agriculture and industry, sustains wetland and riparian ecosystems, and maintains the flow of rivers and streams. In many places, groundwater resources are susceptible to risks of overuse and contamination. Its sustainable management is increasingly critical; especially in climate-sensitive geographic areas such as islands and arid lands.

My main interest is in researching karst groundwater sustainability because aquifers storing groundwater in karst systems are commonly found throughout my home country, Jamaica, and other islands in the Caribbean. In Arizona, the major karst aquifer system is found in the north in the Coconino Plateau area; which includes the city of Flagstaff, and the Grand Canyon region. The physical characteristics of karst groundwater systems make them highly susceptible to pollution and climatic influences. Geologic features of karst landscapes, such as sinkholes, act as quick pathways for pollutants to be transported to the aquifer, given that there are little or no soil layers to filter pollutants en route to the aquifer.

An abundance of water or the lack of it has always featured heavily in my life. I grew up in the tropical island of Jamaica which is known as the “Land of Wood and Water”. Although surrounded by the Caribbean Sea, as you traverse the island you will be hard pressed to travel 5 miles without encountering a stream or water feature. Water is intertwined into every aspect of social, economic and cultural life. As children, we regularly went to the beach and played in a stream adjacent to our family farm, oblivious of the connections to exposure to agrochemical runoff from the farm that provided my family’s livelihood. Religious groups perform rituals such as baptisms in water bodies across the island. Tourism, the main contributor to the national economy, is built around water resources as a key natural asset.
