In Nederland bestaat 11% van het oppervlak uit bossen. Deze bossen vervullen belangrijke functies, zoals recreatie, bron van biodiversiteit en leverancier van grondstoffen voor bioenergie en de bioeconomie. Daarnaast passen bossen in de cultuur en tradities van Nederland. De houtoogst in Nederland is laag – ongeveer de helft van de jaarlijkse bijgroei – en redelijk constant. Diverse (overheids)acties in de afgelopen 20 jaar hebben hier geen verandering in gebracht. Het is belangrijk om de houtoogst te verhogen vanwege de positieve effecten op de staat van het Nederlandse bos en vanwege de toekomstige grotere vraag naar hout. Uit een recente enquête onder particuliere boseigenaren in Twente is gebleken dat de helft van deze eigenaren – goed voor 2/5 van het bos in Twente – niet oogst. Daarnaast is ook gebleken dat een belangrijk deel van deze eigenaren bereid is te oogsten als de omstandigheden zouden verbeteren. In dit Plan van Aanpak zijn een aantal acties opgesteld met als doel de houtmobilisatie onder particuliere eigenaren te verhogen.

De export van boomkwekerijproducten is in 2014 met een kleine 5% gestegen tot € 1.250 mln. Het belang van Duitsland als exportbestemming is de laatste jaren sterk afgenomen. Naar het VK, België en Italië nam de export daarentegen sterk toe. Een gelijkblijvende exportwaarde in 2015 lijkt aannemelijk. De exportwaarde van boomkwekerijproducten steeg in 2014 met een kleine 5%. Omdat de importwaarde zeer klein is, heeft deze nauwelijks invloed op de handelsbalans van boomkwekerijproducten. Hierdoor steeg de handelsbalans van boomkwekerijproducten met deze exporttoename. De toename werd binnen de EU-landen gerealiseerd, want de exportwaarde en handelsbalanswaarde met landen buiten de EU nam af.

forest products - south-africa - dry forests - papyrifera - ethiopia - environment - zimbabwe - trade
African dry forests provide non-timber forest products (NTFPs) of high commercial value, such as frankincense and gum arabic. Nonetheless, their deforestation and conversion to croplands is intensifying. Expected higher financial return from crop production is a main driver of conversion, but research supporting this underlying claim is scarce. We compared the financial returns for two crop production options (sesame and cotton) and forest use, in a dry forest area known for its frankincense production in northern Ethiopia. Net revenue was highest for sesame and lowest for cotton agricultural use. The forest based revenue was intermediate. The revenues from the crop production options were more sensitive to a range of uncertainties than the forest land use. Our results show that forest land use that includes commercial NTFPs is financially competitive to some commercial crop options and offers returns of better reliability. The hypothesis that forest based revenues are lower than crop based ones is not supported by our results. Therefore, the continued deforestation of dry forests cannot be explained by lower returns alone, but other factors such as awareness, market access, property right and institutional issues may also play a role to drive deforestation and conversion of dry forests to croplands.

This book aims at both academics and professionals in the field of forest-people interfaces. It takes the reader on a journey through four major themes that have emerged since the initiation of 'social forestry' in the 1970s: non-timber forest products and agroforestry; community-based natural resource management; biocultural diversity; and forest governance. In so doing, the books offers a comprehensive and current review on social issues related to forests that other, more specialized publications, lack. It is also theory-rich, offering both mainstream and critical perspectives, and presents up-to-date empirical materials. Reviewing these four major research themes, the main conclusion of the book is that naïve optimism associated with forest-people interfaces should be tempered. The chapters show that economic development, political empowerment and environmental aims are not easily integrated. Hence local landscapes and communities are not as 'makeable' as is often assumed. Events that take place on other scales might intervene; local communities might not implement policies locally; and governance practices might empower governments more than communities. This all shows that we should go beyond community-based ideas and ideals, and look at practices on the ground.

Consumption and/or domestic activities in the private domain are much studied subjects. In the field of home economics and related fields of study, the household is the main unit of analysis. This paper focuses on how the household is conceptualized in literature during 2000–2010. The paper contains two lines of investigation. The first questions whether and in which way the household is defined in a selection of peer-reviewed articles of which the concept is part of the title. The second is about the multifaceted nature of the concept and elicits the facets that feature in the articles. A systematic review was performed using the bibliographic database Web of Science, as it covers different branches of science, including, but not limited to, home economics, developmental sociology, environmental sciences and transportation. The search was formulated by means of a Boolean expression. Articles were included when they were written in English, published between 2000 and 2010, and contained Househ* in title and Theor* in the topic, and either member* or product* or care or livelihood in the topic. Abstracts and full papers were assigned to Atlas.ti, a program for computer-assisted qualitative data analysis. Bottom-up and top-down coding procedures were used for a domain analysis and a quantitative content analysis. The results show that very few (less than 10%) of the papers give a definition of the concept ‘household’. Instead, some papers give a study description based on so-called household characteristics, thereby implicitly indicating dimensions of the concept. In the Results sections, some of the characteristics used for inclusion or exclusion of study participants are mentioned, but also other characteristics. It is concluded that descriptions of households do contain commonly used facets that together construct the concept of household as a group of people sharing resources, expenditures and activities.

Forest resource access is often conceptualized as a `bundle of rights` held by different social groups at different times. In Uganda, similar to other parts of the world, professional foresters and scientists concerned with resource conservation have conceived of forests mainly in terms of access rights that are formalized through legal boundaries based upon a strong notion of property (especially State and private) This study argues that local people's access to forest resources is not only based on such formal bundles of legal rights, but also entails local norms and `morals` that regulate access to land and other forest resources. Such `bundles of rights` or `powers` are embedded within specific cultural social, political and economic contexts and are related to intra-community and intra-household power relations, and particularly to gender relations. The most important `bundle of rights` to resources is usually considered to be that relating to land, where it is widely recognised that legal (de jure) and customary (often de facto) tenure may differ significantly

Om tot een beter begrip te komen van de factoren die de rol van niet-houtige bosproducten en diensten in de samenleving en hun plaats in het bosbeleid beïnvloeden is een vergelijkend onderzoek uitgevoerd tussen Nederland en Noorwegen. Vier producten en diensten zijn meer in detail bekeken: jacht, recreatiehuisjes, bessen en paddestoelen, en drinkwater. Een en ander wordt bestudeerd in het licht van de verschillen in bosgerelateerde karakteristieken tussen Nederland en Noorwegen (institutioneel raamwerk; economische karakteristieken; demografie en boskwaliteit/kwantiteit; houdingen, waarden en gebruiken)

In het kader van de streekplanherziening Zuid-Holland Oost is een schatting gemaakt van de toekomstige ruimtebehoefte voor de boomteelt in de regio Boskoop tot 2015. Op basis van toekomstige ontwikkelingen in de vraag naar boomteeltproducten, de (inter)nationale concurrentiepositie van de boomteelt in de regio Boskoop en de bedrijfsstructuur is de extra ruimtebehoefte geschat op 2% per jaar. Het totale areaal boomteelt in 2015 komt hiermee op 1.435 ha (+ 335 ha), waarvan de helft pot- en containerteelt en de helft in de vollegrond. Ook zal tot 2015 de teelt onder glas gestaag toenemen. Om het boomteeltcentrum in de regio Boskoop in stand te houden is niet alleen behoefte aan extra ruimte, maar zal ook voldaan moeten worden aan een aantal kwalitatieve randvoorwaarden. De belangrijkste randvoorwaarden zijn: planologische zekerheid, ruimte voor ondersteunend glas, goede bedrijfsstructuur, goede infrastructuur, kwalitatief goed opgeleid personeel en professioneel ondernemersschap

<p>Relationships between exposure to mould spores, IgG antibodies against moulds and respiratory and febrile symptoms were studied among wood trimmers. A new method for quantitative assessment of mould spore exposure by scanning electron microscopy was developed. This method was validated by comparison with other microscopical methods. The precision of mould counts was in accordance with expectations if aggregation of mould spores was taken into account. Specific IgG antibody levels, which are biomarkers of exposure, were correlated with exposure levels to spores from the corresponding mould species. Respiratory symptoms were correlated with factors associated with mould spore exposure, exposure measured in the working environment and specific IgG antibody levels to moulds. Antibodies to the most prevalent mould among those assessed by serology, <em>R. microsporus</em> , was the best indicator of retrospectively recorded symptoms, especially when the average antibody level in groups of sawmill workers working in the same working area was used. The results support the hypothesis that exposure to mould spores may cause respiratory symptoms in wood trimmers.
