Agriculture production is highly dependent on water and increasingly subject to water risks; and is the largest using sector and a major polluter of water. Improving agriculture’s water management is essential to a sustainable and productive agro-food sector.

The OECD actively participated in this event on the theme “Water for society – Including all” from 25-29 August through a series of events and by taking part in a number of workshops and seminars. Read more on the programme.

Today, management of water resources is one of the major challenges confronting Israel. Accelerated population growth - along with economic growth - has placed additional pressure on Israel's limited water resources but the country is at the forefront of green innovations for water management.&l

Climate change and rising demand are making it harder to meet the world’s water needs. At World Water Week 2013, the OECD will explore how to better manage this vital resource.

The OECD participated in this annual event held in Stockholm (1-5 September 2013) where two major reports "Water Security for Better Lives" and "Water and Climate Change Adaptation: Policies to Navigate Uncharted Waters" were launched by the OECD's Secretary-General, Angel Gurría.

Water shortages and floods illustrate the risks posed by too little, or too much, water. By 2050 more than 40% of the world’s population will live under severe water stress and nearly 20% could be exposed to floods.

Water security is one of the greatest challenges we face today, yet the situation has never looked more perilous. By 2050 the OECD Environmental Outlook projects that nearly 4 billion people will live in river basins under severe water stress, and global nitrogen effluents from wastewater are projected to grow by 180%. Whilst, over the same period, global demand for water is expected to grow by 55%.

Ministers from OECD’s 34 member countries today welcomed the new OECD Principles on Water Governance, which set standards for more effective, efficient and inclusive design and implementation of water policies, and encouraged governments to put them into action.

Rapid population growth, ageing infrastructure and new weather risks are straining the ability of cities in OECD countries to provide clean water and to protect against floods and droughts, according to a new OECD report. Cities will need large-scale investment and more effective tariffs and taxes to pay for upgrades to water systems.

This paper is part of the regional development working paper series covering water governance in Latin America and the Carribbean (LAC) countries.

In Latin American and Caribbean countries the population is growing faster than the world average, intensifying land use and increasing urbanisation. The region is also prone to the negative impact of climate change and natural disasters, putting further pressure on natural resources.

Mexico’s river basins are under severe water stress. The quality of rivers, lakes and aquifers is declining and floods, droughts, and hurricanes are more frequent. These are some of the alerts signaled in OECD’s Making Water Reform Happen in Mexico.

The Netherlands is a global pioneer in water management with a long history of containing flood risks and reclaiming land from the sea. Yet it will need to adapt its water governance policies to meet the looming challenges of shifting demographics, regional development and climate change, according to an OECD report.

The recent droughts in Brazil’s Rio de Janeiro and São Paulo states have exposed the need to shift from crisis management to effective risk governance of the country’s water resources, according to a new OECD report.

Owing to their combined open-framework structures and semiconducting properties, two-dimensional thio­stannates show great potential for catalytic and sensing applications. One such class of crystalline materials consists of porous polymeric [Sn3S72−]n sheets with molecular cations embedded in-between. The compounds are denoted R-SnS-1, where R is the cation. Dependent on the cation, some R-SnS-1 thio­stannates transition into amorphous phases upon dispersion in water. Knowledge about the fundamental chemical properties of the thio­stannates, including their water stability and the nature of the amorphous products, has not yet been established. This paper presents a time-resolved study of the transition from the crystalline to the amorphous phase of two violet-light absorbing thio­stannates, i.e. AEPz-SnS-1 [AEPz = 1-(2-amino­ethyl)­piperazine] and trenH-SnS-1 [tren = tris­(2-amino­ethyl)­amine]. X-ray total scattering data and pair distribution function analysis reveal no change in the local intralayer coordination during the amorphization. However, a rapid decrease in the crystalline domain sizes upon suspension in water is demonstrated. Although scanning electron microscopy shows no significant decrease of the micrometre-sized particles, transmission electron microscopy reveals the formation of small particles (∼200–400 nm) in addition to the larger particles. The amorphization is associated with disorder of the thio­stannate nanosheet stacking. For example, an average decrease in the interlayer distance (from 19.0 to 15.6 Å) is connected to the substantial loss of the organic components as shown by elemental analysis and X-ray photoelectron spectroscopy. Despite the structural changes, the light absorption properties of the amorphisized R-SnS-1 compounds remain intact, which is encouraging for future water-based applications of such materials.

By using small-angle neutron scattering (SANS) reinforced by scanning electron microscopy, the fine structure of catalysts for polymer electrolyte fuel cells has been investigated. The experimental data resulting from contrast variation with mixed light and heavy water (H2O/D2O) are well described by a core–shell model with fluctuations in concentration between water and Nafion.
