Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. To determine the value of enhanced crop pollination as a means of ecological intensific

Jordbrukets intensitet har under de senaste decennierna ökat genom effektiviserad teknikanvändning och ökade insatser av pesticider och växtnäring. Detta har inte bara lett till ökade skördar utan även till negativa konsekvenser för den biologiska mångfalden i jordbrukslandskapet.I denna studie inventerades förekomsten av kärlväxter i 160 höstvetefält (Triticum aestivum L.) på 32 gårdar i Uppsala-

We examine if international trade improves labor market integration of immigrants in Sweden. Immigrants participate substantially less than natives in the labor market. However, trading with a foreign country is expected to increase the demand for immigrants from that country. By hiring immigrants, a firm may access foreign knowledge and networks needed to overcome information frictions in trade.

The 2015 Paris Agreement encourages stakeholders to implement sustainable forest management policies to mitigate anthropogenic emissions of greenhouse gases (GHG). The net effects of forest management on the climate and the environment are, however, still not completely understood, partially as a result of a lack of long-term measurements of GHG fluxes in managed forests. During the period 2010–20The 2015 Paris Agreement encourages stakeholders to implement sustainable forest management policies to mitigate anthropogenic emissions of greenhouse gases (GHG).

Adolescent mental health is key for later well-being. Yet, causal evidence on environmental drivers of adolescent mental health is scant. We study how an important classroom feature---the gender composition in compulsory-school---affects mental health. We use Swedish administrative data ($N=576,285$) to link variation in gender composition across classrooms within cohorts to mental health. We find

The situation in East Timor is turbulent and future growth prospects are indeterminate. This paper discusses the economic challenges facing East Timor. Most inhabitants depend on subsistence farming and there is a need to both modernize agriculture and to foster a modern sector that can generate employment for the growing population. Public expenditures play an important role in this development a

The book is monograph on the work of Swedish filmmaker and visual artist Lena Mattsson (b. 1966) with an introductory essay by Andersson, and two texts by Wiberg and Nilsson respectively. The book is illustrated with photographs and film stills from the whole of Mattsson's career, but the main focus is on her recent projects.A monograph on the art of visual artist and filmmaker Lena Mattsson, Sweden (b. 1966). The book includes a lengthy essay by Andersson and two brief texts by Wiberg and Nilsson, and is furthermore illustrated with photographs and film stills from the whole of Mattsson's career. Focus is on her recent works, though.
