LTLS Analysis and simulation of the Long-Term / Large-Scale interactions of C, N and P in UK land, freshwater and atmosphere

www.ltls.org.uk

"The sustainability of our world depends fundamentally on nutrients. In order to feed 7 billion people, humans have more than doubled global terrestrial cycling of nitrogen (N) and phosphorus (P).
The world’s N and P cycles are now out of balance, causing major environmental, health and economic problems that have received far too little attention.
Insufficient access to nutrients still limits food production and contributes to land degradation in some parts of the world, while limited P reserves represent a risk for future global food security.
Unless action is taken, increases in population and per capita consumption of energy and animal products will exacerbate nutrient losses, pollution levels and land degradation, further threatening the quality of our water, air and soils, affecting climate and biodiversity."
From Our Nutrient World

The LTLS project aims to provide scientific knowledge that can help to address these problems. Our project is based on the UK, a region of the world which has seen enormous changes in nutrient levels and movements over the last 200 years.
We plan to assemble, enhance and analyse the large amount of data that has been gathered for the UK, in order to explain the present nutrient status of the country’s plants, soils, rivers, lakes and groundwater. If we can do that convincingly, we will have a basis for predicting and managing future changes.

The LTLS project began in October 2012 and is scheduled to finish in late 2015.
