    The discursive structure of FLEGT (Forest Law Enforcement, Governance and Trade): The negotiation and interpretation of legality in the EU and Indonesia

    The FLEGT (Forest Law Enforcement Governance and Trade) initiative is among the recent attempts to combat deforestation and promote sustainable forest development. However, ideas about what the objectives of FLEGT are and how legality should be interpreted differ among different actors involved. Some advocate a narrow interpretation of legality that promotes a strong role of the state and focuses on law enforcement, while others advocate a broader interpretation that includes issues of participation and sustainability. These different interpretations mirror current developments in international forest governance which are influenced on the one hand by broader trends in governance, which focus on voluntary instruments, participation and marketization, while on the other hand, the nation state remains a very powerful actor. This article uses a discourse analytical approach to analyze the discursive structure of FLEGT, particularly the European Union FLEGT Action Plan and the Indonesian legality standards. Our findings show that FLEGT is first and foremost shaped by state oriented discourses that promote regulatory instruments and a narrow interpretation of legality. Sustainability and participatory considerations are present, both in the EU and in the Indonesian context, but they come in a secondary position. The article concludes by positioning these findings in the international forest governance debate and by discussing the implications of the discursive structure of FLEGT for sustainability, participatory governance and the state.

    Gonadal development and spawning behaviour of artificially-matured European eel (Anguilla anguilla L.) was studied. Treatment of males with Human Chorionic Gonadotropin (HCG; 1 IU g/week) resulted in a Gonado-Somatic Index (GSI) of 10.88 ± 3.39 and spermiation. Treatment of females with carp Pituitary suspension (cPs) (20 mg cPs/kg body weight per week) resulted in oogenesis with a GSI of 20.0 ± 11.3 (n = 7), and the number of eggs per female was 1874 * 103 ± 1116 * 103; (n = 7). Ovulation of the females was induced with 17, 20 dihydroxyprogesteron (DHP) at 2 g/g bodyweight. Eggs of European eel were found to be non-sticky and typically pelagic. Maximum speed of eggs rising to the surface in a water column was 2.24 ± 0.33 metres (m) per hour (h). To study behaviour in a qualitative way, two females were used together with three groups of three males. During a 283 minute (min) observation of the two females, we observed female-female interaction: 'lethargic behaviour' (33.6%) vs. 'cruising together' (66.4%). In the period when males and females were together (188 min), we observed 'approaching the head region of the female' (57.7%), 'touching the operculum' (39.4%), or 'approaching the urogenital area' (2.9%) by the males (total 725 seconds (s)). Sperm release in the presence of a female took 115 s of the total approaching time of 725 s (15.9%), while in the case of male-male interaction this was only 15 s of the total period of 116 s (12.9%). Induced spawning behaviour of eels was collective and simultaneous, corresponding to spawning in a group. This is the first time group spawning behaviour has ever been observed and recorded in eels
