Nitrates in Groundwater

Products from the wild, also known as non-timber forest products (NTFPs), are used as medicines, foods, spices, and a multitude of other purposes. They contribute substantially to rural livelihoods, generate revenue for companies and governments, and have a range of impacts on biodiversity conservation. However, there is little information available for those seeking to develop effective policy frameworks and regulation.

From the pre-historic era to modern times, cereal grains have been the most important source of human nutrition, and have helped sustain the increasing population and the development of human civilization. In order to meet the food needs of the 21st century, food production must be doubled by the year 2025, and nearly tripled by 2050. Such enormous increases in food productivity cannot be brought about by relying entirely on conventional breeding methods, especially on less land per capita, with poor quality and quantity of water, and under rapidly deteriorating environmental conditions.

Meager water supply causes severe problems in the growth of plants, which rely on sufficient water transmitted by the soil to meet their needs. This new edition of Water Dynamics in Plant Production describes the basic scientific principles of water transport in the soil-plant-atmosphere continuum, explains the linkage between transpiration water use and dry matter production paying particular attention to the various agronomic strategies for adaptation to climate-driven limitations of water resources.
