AbstractThis article examines the development of Singapore's Gardens by the Bay, a parkland and botanical gardens complex on a reclaimed land platform which opened in 2012. It provides three readings of the development based on different types of technopolitical governance. First, it discusses the significance of the location of the Gardens on one of Singapore's reclaimed land platforms, part of the 'terraforming' strategies of the government's land development process. Second, it situates the project within the state's complex botanical relationship with colonial and postcolonial knowledge circuits, and suggests that this is part of the governance challenge of 'acclimatizing' to the tropical climate. Third, it suggests that the Gardens are part of an 'exhibitionary complex' based on engaging publics with the state's ability to harness science to provide a controlled, ordered polity. To illustrate this, the article brings together the political discourse of two Singaporean prime ministers with a discussion of the architectural design and environmental engineering of the project, and the curatorial practices of the state's National Parks Board. The article demonstrates the complex interplay of environmental, architectural and botanical engineering with state strategies of both citizen engagement and tourist attraction, and the importance of the practice of exhibition within urban megaprojects.

Conservation areas with the objective for collection and exchange plant materials have been speculated as weed bank for surrounding areas. Objective of this study was to identify and characterize ruderal invasive weeds in the Bogor Botanic Gardens (BBG). Observations were conducted in all vak (collection blocks) in the BBG in order to identify the weeds species, determine their invasiveness, dominance and distribution. Weeds associations with host plants were observed. Current weed control program and data of dead trees collection were analyzed in relevant to weed. Distribution of weeds outside BBG was observed by transects method following river and road directions. Results showed that there were seven invasive weeds, i.e., Cecropia adenopus (Cecropiaceae), Cissus nodosa Blume (Vitaceae), Cissus sicyoides Blume (Vitaceae), Dioscorea bulbifera L. (Dioscoreaceae), Ficus elastica Roxb. (Moraceae), Mikania micrantha H.B.K. (Asteraceae) and Paraserianthes falcataria (L.) Nielsen (Fabaceae). These seven weeds species invaded 41 out of 215 plant families in BBG. Six species of weeds, i.e., C. adenopus, C. nodosa Blume., C. sicyoides Blume., D. bulbifera L., M. micrantha H.B.K. and P. falcataria (L.) Nielsen, were introduced as BBG collections for the first time while the F. elastica Roxb was considered as native. It is most likely that the weeds dispersal agents are the wind, birds, bats, visitors, and waters. All of these weeds existed in surrounding areas outside BBG. Given the detrimental impact of invasive weeds on the plant collection in BBG, it is necessary to develop long–term comprehensive control measures both inside and neighboring areas by involving other government authorities beyond BBG.

Indonesia holds a large percentage of Malesian Sapotaceae taxa with an estimated 15 genera and 158 species. Bogor Botanic Gardens currently hold 12 genera and 41 species of which 29 are native to Indonesia. This represents just under 20% of Sapotaceae species currently recorded from Indonesia. The utility of these collections is dependent on the type of data associated with them and on the quality of identification of the material. Of the 29 native species only three have had a global threat assessment made and, of these, one, Madhuca boerlageana (Burck) Baehni, is considered Critically Endangered. The regional botanic gardens initiative of the Indonesian government is establishing botanic gardens in each of the 47 ecoregions of Indonesia. This new initiative is potentially very important for in situ and ex situ conservation of the Indonesian flora. So far it has brought into cultivation 39 threatened species, however none of these are Sapotaceae. The lack of global IUCN threat data is a major impediment to the prioritisation of collection, cultivation and conservation of Sapotaceae species.

Abstract
Islamic environmentalism has increased within the last several decades in the Muslim world and in Muslim-minority countries. The Arab Gulf is one of the regions in which environmentalism – let alone Islamic environmentalism – has been greatly understudied. This paper aims to partially fill this gap by exploring the Qur'anic Botanic Garden (QBG) in Qatar as an illustrative – albeit imperfect – example of Islamic environmentalism, combining environmental aspirations of many modern botanic gardens with religious and cultural aims. After briefly introducing Islamic environmentalism and the significance of environmentalism in the Arab Gulf region, I draw on field research conducted in Qatar to elucidate how the QBG utilizes Islamic scripture, beliefs, and values to articulate its vision and objectives. This paper also examines how QBG leaders' religious and cultural views influence environmental advocacy within the QBG and beyond. Finally, this research critically explores the QBG's potential impact on socio-environmental realities in Qatar. While the QBG may succeed in making intellectual advancements and promoting religious and ecological values, this paper posits that such a state-sponsored institution's inability to politicize ecological degradation demonstrates the difficulty of reforming development models to achieve more socially just and sustainable ends. I conclude that the broader potential of Islamic environmentalism lies in its ability to unite Muslims and people in the Arab Gulf region behind a shared socio-environmental vision. Its efficacy also comes from mobilizing people to advocate alternative development models prioritizing the integrity of all people and honouring planetary boundaries over economic growth or political gain.

Mass digitization is a large undertaking for a collection. It is disruptive of routine and can challenge long-held practises. Having been through the procedure and survived, we feel we have a lot of experience to share with other institutions who are considering taking on this challenge. The changes that digitization has made to our institution are positive and the digitization a success, but that is not to say that we would not have done some things differently, were we to repeat the exercise. In 2015 Meise Botanic Garden received a grant from the Flemish Government to upgrade its digitization infrastructure and mass digitize 1.2 million specimens from its African and Belgian Herbaria. The new infrastructure improved our workflow significantly, enabling us to digitize specimens five to ten times faster while also improving their quality. The mass digitization part of the project was split into two parts, imaging and transcription. The contract was awarded and out-sourced to Picturae, who started imaging in May 2016 using a conveyor belt installation. Prior to starting, a significant amount of preparation was required at the herbarium. Within one year, 1.2 million specimens were imaged. The images were captured as TIFF files and stored in triplicate at The Flemish Institute for Archiving (VIAA), while smaller derived JPEG 2000 and JPEG files were generated for day-to-day use. The second part of the project was label transcription. A third of the specimens were transcribed in-house for capturing minimal data (barcode, filing name, collector, collector number & country of origin). This was partly done to reduce costs, but also allowed us to compare in-house to out-sourced transcription. Some 500,000 specimens were transcribed, either completely or partially, by Alembo (subcontracted by Picturae).The remaining 200.000 specimens from our Belgian Herbarium are being transcribed using crowdsourcing. The latter is being realized through the citizen science platform DoeDat (www.doedat.be) that was launched in ...

Botanic gardens' purposes have varied in time and space from their medicinal origins in the Italian universities to the somewhat multi-purpose function they have today. The history of the Brussels Botanic Garden, established as a company in 1826, suggests that it was first fashioned by the then leading-class and its needs: it tended to focus on agricultural and industrial developments as well as selling luxury goods. Later, as a State institution from 1870 until the First World War, the Botanic Garden had to deal not only with the diversification of disciplines and new trends in the sciences, but also with growing democracy alongside the concomitant political and philosophical issues. In such a context dreams of "pure" science, like taxonomy and floristics, had to cope with practical and political issues linked to the growing social demands and the garnering of votes.

Many lessons have been learnt with respect to implementing mass digitization, both practically and sociologically. Many of the problems encountered during the project could have been avoided by changing the workflow. The addition of extra control points during the process could have reduced problems encountered later in the data capture process. Solving these problems at a later stage was time consuming. Trying to "save money" can result in a disruptive workflow, which may lead to a number of costly errors. Mass digitization has fundamentally changed the workflow in our collections and the way in which our herbarium is managed. All images for the African and Belgian collections may be now found on our new virtual herbarium www.botanicalcollections.be.
