English summary report: Supermarkets on the move for sustainable crop protection

Authors: Eric Hees, Peter Leendertse en Erwin Hoftijser

April 2016

Chemical pesticides and their negative effects on humans and the environment are currently topics of great interest. Attention has focused on the possible impact of neonicotinoids (a group of insecticides) on bee mortality and other effects on the ecosystem, exceedances of water quality standards for natural habitats and drinking water and the possible effects of spraying for local residents.Plant protection products differ greatly in the risks they pose for the surroundings. Reducing total use is therefore only part of the solution. It is particularly important to reduce the use of high-risk products. Change can be achieved through a twofold strategy: making optimal use of (inter)national knowledge and practical experience with non-chemical measures and ecological methods, while at the same time reducing the environmental effects of chemical plant protection.

Report: A strategy for a more sustainable agricultural sector

Report: A strategy for a more sustainable agricultural sectorIncluding the CAP as an effective instrument for sustainable development

Auhtor: Claudia Rieswijk (trainee CLM)

December 2015

The Common Agricultaral Policy (CAP) could be much more effective for climate, as well as soil, water and biodiversity. The report states how CAP can make the future more "green". The conclusions are partly based on the input of 20 stakeholders and several farmers from all over the country. The research is an extensive evaluation of the impact of the current CAP on the Dutch agriculture. It also reflects how the CAP could be more effectively put to use, to enhance a healthy agriculture in the future. The report shows that an important improvement can be made in involving and enthusing farmers. A critical look on the effect of farming payments would also be a good idea. Both policy makers and entrepreneurs are in doubt wether those payments achieve the desired effects. Another important conclusion is the underestimation of the power of the second pillar, also known as POP.

Report: LCA of Dutch pork

GLAMUR report LCA of Dutch pork, assesment of three pork production systems in the Netherlands Assesment of three pork production systems in the Netherlands

Authors: Carin Rougoor, Emiel Elferink, Tjerk Lap en Annelies Balkema

May 2015

Three different pork production systems in the Netherlands are compared in a LCA using 5 environmental impact categories, namely global warming potential, fossil energy use, eutrophication potential, land use and water use. The local pork production system using locally cultivated and residual food products as feed and on farm produced bio-energy has the lowest environmental impacts in all 5 categories. Cultivation and transport of feed products and to a lesser extent manure management are the process steps where the largest environmental
impacts occur for all cases.

Article: Effective agri-environmental management requires adequate monitoring

Article: Effective agri-environmental management requires adequate monitoringAuthors: Wouter van der Weijden en Adriaan Guldemond

May 2015

Our knowledge regarding the effectiveness of agri-environmental management is still incomple. Therefore, monitoring must be improved. The Dutch government has been subsidising agri-environmental management by farmers since 1981. However, a fierce debate regarding its ef­fectiveness has been going on for decades. This is, for a large part, due to the fact that the results of this type of management have not been system­atically monitored, and some fauna! groups (fish, for instance) have not been monitored at all. Consequently, it is often impossible to distin­guish clear connections between management and changes in populations. This is detrimental in three respects: to farmland biodiversity, it negatively impacts the motivation of the participating farmers and vólunteers and it is harmful for the government and the tax­paying society, who want to know if their money is being spent effectively. If this remains unclear, agri-environmental management is at risk of be­ing shut down.
