Global trends in cereal and meat production; total use of nitrogen and phosphorus fertilizers; increased use of irrigation; total global pesticides production

Production gains are attributed to improved crop varieties and livestock, soil management, improved access to resources (nutrients and water), infrastructure developments, policy initiatives, microfinance, education, better communication and advances in market and trade systems. This has also increased the demand and use of irrigation, phosphorus and nitrogen.

Solid waste management cost for selected cities

As garbage piles up, however much space we set aside for landfill, we are beginning to realise that producing waste at this rate is no longer viable. It is time for the three “Rs”: Reduce, Reuse, Recycle and integrated waste management. Waste management strategies are as diverse as waste itself. But whatever we do there is no escaping the “waste of waste” (unless we rein in our greed and buy less).

Water management in Central Asia: state and impact

The problems precipitated by this crisis have aggravated the social and economic difficulties caused by the collapse of the Soviet Union. Following the break- up of the Soviet Union the interests of Up-strea...

Not only are there benefits from the grown products, depicted in this figure,...

Transboundary river basins of the Balkans, detail

All the Balkan countries are now committed to the European integration progress, with the goal of joining the European Union. They must consequently accept the acquis communautaire and transpose it into their national legislation. One major challenge – and not just for new member states – is the Water Framework Directive, which introduces new rules for water management hinging on transboundary river basins.

Transboundary river basins of the Balkans, overview

Prior to 1992, there were only six transboundary river basins in the Balkans, but after the break-up of former Yugoslavia, the number more than doubled. There are now 13 internationally shared river basins and four trans-boundary lake basins. Such a fragmented situation means that new international legal regimes specifically for water basins need to be worked out. Talks between the countries concerned are also essential to develop future policies...
