Outline of Final Research Achievements

The main achievements of my research were as follows; (1) Unraveling the post-war changes in agricultural practices and their effects on farmland biodiversity by literature review (Agrit. Syst.), (2) Quantifying the effects of organic and low-input farming on farmland biodiversity and the trade-offs between yield and biodiversity, by large-scale field surveys and statistical modelling (Sci. Rep., Ornithol. Sci., and in preparation), and (3) Understanding the effect of rice-field abandonment and fallow on biodiversity by a meta-analysis (Cons. Biol.) .
