The effects of market regulation and environmental policy on eight types of renewable energy in the EU are identified in a study which examines nearly three decades’ worth of data. The researchers found that reducing entry barriers is a major driver of renewable energy innovation and that the ability of environmental policy to promote renewable energy innovation depends on the technology; for example, quota systems appear to work better with older technologies.
Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season.
Non-conservative tillage techniques, such as milling and harrowing, are the most common way to manage soil in Mediterranean olive orchards. A new study confirms the value of alternative methods based on the use of spontaneous cover crops which can significantly improve soil structure and reduce erosion whilst maintaining yields.
A reforestation project has revitalised its surroundings just 80 years after its inception. In the late 1920s, the Saldaña badlands in northern Spain were a barren region, with a thin layer of intensely weathered soil, and only 5% vegetation cover. Now that cover has increased dramatically to 87%, the soil quality is improving, and the water flow in the area has stabilised, bringing greater environmental security to the local community.
Water scarcity is an important cause of low crop yields worldwide. Yields could be significantly improved by focusing attention on unproductive water losses and improving retention of plant-available water in soils, and particularly the largely unexplored interactions between soils and roots. A new review of scientific literature sets out key soil management measures for crops under drought conditions.
Comprehensive data analysed in a new study show how extensive rainfall can erode soils across the EU and Switzerland, revealing that Mediterranean regions have the highest risk for erosive events and floods. The resulting dataset can also be used for disaster planning and relief.
Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study investigated the impact of ERA on agricultural fields in Finland, showing that the practice can reduce nitrogen leaching and may help to achieve agricultural nitrogen-reduction targets.
Worsening soil erosion in north-western Europe may be the result of a switch from traditional dairy farming to cash crops. However, even if all dairy farming ceased, reductions in runoff of up to 76% could be achieved if best agricultural practices are employed, at a cost of approximately €45 per hectare for the first three years, new research from the Austreberthe watershed in France suggests.
An extensive field investigation discovered that 38% of soils in southwest England show signs of enhanced surface water runoff due to soil degradation. The study also revealed which types of fields and soils are linked to the most or least degradation.
Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient run-off that would have affected neighbouring waterways.
In the face of substantial evidence that modern land use management practices have increased runoff at the local scale, a new study reveals changes in local land use management practices can reduce the risk of local flooding. However, there is little evidence so far that these local increases in runoff culminate in large-scale flooding effects. To address this lack of evidence, the researchers present a model that maps the downstream rate of flow back to its source areas.
Land use changes over the last century in the Mediterranean area may be sparking shifts in weather patterns locally, across Europe, and around the globe, suggests a new study. The findings bring to light new complexities that can be integrated into climate models and predictions.
Land use changes over time have altered relations between soils and water cycles throughout the world. Soils have been lost and degraded, and the closely interlinked processes of soils and water have become an urgent issue for European policymakers. This Thematic Issue aims to provide a review of new research into the links between soil and water issues in Europe, including a message that the soil-water links must be considered at their proper spatial scales.
