Slash-and-mulch : Exploring the role of shrub-based agroforestry systems for smallholder farmers in the Sahel
Agriculture in the lowlands of south Brazil is of strategic importance at the national level, since it supplies around 80% of the rice consumed by the Brazilian population. In Rio Grande do Sul, the southernmost state in Brazil, three million hectares of lowlands are ready for grain-based agriculture. Of this area, about half is fallow, partly used...
Potato has multiple benefits and thus can play a vital role in ensuring food security in Ethiopia. However, for diverse reasons, its productivity is low. The farming systems in Ethiopia in which potato is grown, are predominantly mixed farming systems. Most of the research in Ethiopia is focused on crop-specific constraints and thus there is limite...
Microalgal triglycerides (TAGs) are promising feedstocks for the commodity markets (i.e. food, chemical and biofuel). Nevertheless, microalgal TAGs are not yet economically feasible due to the high production costs. To reduce these costs, TAG productivity needs to be maximized. The aim of this thesis was to increase microalgal TAG productivity by i...

.Abstract long Global demands for food and biofuels increase rapidly, together with an increase of concerns for depleting fossil resources and climate change. New sustainable sources of vegetable oil, from now on referred to as triacylglycerol (TAG), are therefore highly desired. Arable land to produce these TAGs is however limited. Microalgae have...
The increasing world population and living standards have enlarged the demand for food, feed, and for chemicals. Traditional fossil fuel based commodities need to be replaced, not only because these resources are finite, but also to relieve the impact of carbon emission and pollution, resulting from fossil fuel derived processes. Much attention is ...
Kunnen bedrijven nog wel ontwikkelen na de komst van de Melkveewet en fosfaatrechten? Onderzoekers in Wageningen brachten via een rekenmodel de gevolgen in kaart. Zij concluderen dat het interessant blijft om beschikbare stalcapaciteit te benutten en dat fosfaatrechten niet snel de limiterende factor zijn.
Thesis abstract The thesis explored how the global market for Nile Perch fish has reconfigured the social and the natural in dramatic ways. The demand for Nile Perch and Dagaa played, willingly or unwillingly, an important role in converting its products into regionally and globally desired commodity. It has also simultaneously restructured the org...
Vanaf 2011 heeft het Praktijkonderzoek Plant & Omgeving (PPO) sector Fruit te Randwijk het rassenonderzoek met zwarte bessen gedurende vier jaren voortgezet. Het doel is (nieuwe) rassen te zoeken en te toetsen onder Nederlandse (Zeeuwse) teeltomstandigheden, die een verbetering kunnen zijn van de huidige rassen voor wat betreft de productiviteit, d...
