Agriculture is the major user of water in most countries. It also faces the enormous challenge of producing almost 50% more food by 2030 and doubling production by 2050. This will likely need to be achieved with less water, mainly because of growing pressures from urbanisation, industrialisation...

Groundwater has provided great benefits to agriculture irrigation in semi-arid OECD countries, but its intensive use beyond recharge in certain regions has depleted resources and generated significant negative environmental externalities. The report provides a characterisation of the diversity...

Improving water quality is consistently ranked as a top environmental concern in OECD public opinion surveys. The key challenges for policy makers in addressing water quality issues in agriculture are to reduce water pollution while encourage benefits, such as maintaining aquatic life. This book...

Climate change is expected to increase the frequency and magnitude of extreme weather events, notably of droughts and floods to which the agriculture sector is particularly exposed. While agricultural productivity growth and policy development have allowed to better cope with these risks and...

This Test Guideline lists methods for determining the density of liquids and solids, giving only a very succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in kg/m3. Several methods are for liquid substance only: hydrometer,...

This Test Guideline describes methods to measure the viscosity of liquids. The methods listed are appropriate in principle for the investigation of Newtonian liquids. The measurement of non-Newtonian liquids is only possible with the rotational viscometer. Viscosity measurements are carried out...
