The aim of the project Biobased Fertilisers Achterhoek (‘Kunstmestvrije Achterhoek’ in Dutch) is to make fertilisation practices more sustainable through the use of locally available nutrients from renewable sources. The project is part of the Sixth Action Programme of the Netherlands which serves the Nitrates Directive. One of the objectives was t...

Extensieve melkveehouderijen en akkerbouwbedrijven hebben verdienmodellen nodig om duurzaam bij te kunnen dragen aan doelen op het gebied van biodiversiteit en waterkwaliteit. Dit rapport presenteert en analyseert rekenvoorbeelden van verdienmodellen op basis van (combinaties van) lagere kosten, hogere opbrengsten en ontwikkelmogelijkheden voor het...

As a growing demand for food and feed resources arises, alternative feed and food resources are sought to relieve pressures on the environment and existing food and feed resources. One alternative that has been given increasing interest is the application of black soldier fly (BSF) larvae to waste streams. In the context of the biobased economy, bl...
Intercropping is the simultaneous cultivation of two or more crop species in the same field. It has been practiced in China for thousands of years. In recent decades, researchers in several disciplines have shown increasing interest in intercropping systems, due to their potential to generate higher yields and counteract resource degradation. Much ...
The smallholder agriculture sector in East Africa is the dominant economic and social activity for millions of farm households who are often resource-poor, food-insecure and most vulnerable to climate change. In this region, population pressure has led to shorter fallow periods or continuous cropping even on hillslopes causing erosion and leading t...
Many monoculture forests (dominated by a single tree species) have been converted to mixed-species forests (dominated by more than one tree species) in Europe over the last decades. The main reason for this conversion was to increase productivity, including timber production, and enhance other ecosystem services, such as conservation of biodiversit...
Yield gap analysis is useful to understand the relative contribution of growth-defining, -limiting and -reducing factors to actual yields. This is traditionally performed at the field level using mechanistic crop growth simulation models, and directly up-scaled to the regional and global levels without considering a range of factors intersecting at...
