A swelling global population and the continued destruction of the natural world are helping to accelerate climate change. Nuclear and isotopic techniques provide data on water use including losses through soil evaporation and help optimize irrigation scheduling and improve water use efficiency. Overview. Meanwhile, our drinkable water sources are finite: Less than 1 percent of the earth’s freshwater is actually accessible to us. Agriculture in many parts of the world is highly efficient in producing and delivering high-quality products to consumers. The Most Common Types of Water Contamination Agricultural.
