This paper discusses the status of food security in Banten Province, Indonesia based on regional and city characteristics. Secondary data is used and is analyzed descriptively covering population dynamics, the population living in poverty, cereal production, disaster risk and soil types. Tangerang Region is found to have the largest population with the greatest number of people living in poverty among the regions and cities in Banten Province. Cereal production is dominated by the regions rather than the cities due to their vast area. Regarding arable land, flooding is the most threatening disaster in the major rice producing areas. In order to identify the distributions of regions and cities regarding food security, three indicator variables of food security dimensions are plotted, namely, cereal normative consumption, proportion of the population living in poverty, and proportion of malnourished babies. The three regions of Pandeglang Region, Lebak Region and Serang Region are grouped together in a less secure group.

Molecular systematics demonstrate that carnivorous plants have evolved at least ten times independently, in five orders, 12 families, and 19 genera of angiosperms. Carnivory has arisen once in Nepenthales (a segregate of Caryophyllales), once in Oxalidales, twice in Ericales, and three times each in Lamiales and Poales. Estimated crown ages of these ten lineages range from 1.9 to 81 million years (Mya), with the youngest three lineages (1.9 – 2.6 Mya) being all single genera of Poales, and all involving one or two carnivorous species in an otherwise noncarnivorous group. We now understand the evolution of carnivorous plants based on knowing when and (often) where they diverged from specific noncarnivorous ancestors; inferring which traits were gained, which were retained, and which of the latter may have been crucial preadaptations for carnivory; and identifying the evolutionary drivers of carnivory by evaluating the ecological differences between carnivorous plants and their noncarnivorous relatives.

AbstractTransnational cooperation is a common strategy for addressing research and development (R&D) issues resulting from similar challenges that cut across administrative borders. Value chains for food and drinks are complex, and transdisciplinary work is recognised as a method for solving complex issues. The Northern Cereals project ran from 2015 to 2018, and its goal was to increase cereal production and the value of grain products in four regions in the Northern Periphery programme area. The project included both R&D, but the main emphasis was on development, and was carried out by transdisciplinary cooperation between R&D partners and small and medium-sized enterprises (SMEs). By reviewing the project’s methods, outcomes and composition, we discuss if a framework of transnational and transdisciplinary cooperation can help to develop the value chain from local barley to beer. We found that transnational cooperation was achieved successfully, that stakeholder involvement was crucial, but that academic disciplines such as marketing and innovation could have been included. In addition, we recognised that much work remains to further increase cereal production and the use of local grain in the Northern Periphery region, but believe that this project has laid a good foundation for further progress.
