Abstract. Sofiyanti N, Isda MN, Juliantari E, Pranata S, Suriatno R. 2019. The inventory and spore morphology of ferns from Bengkalis Island, Riau Province, Indonesia. Biodiversitas 20: 3223-3236. Bengkalis Island is one of main islands at coastal region of Riau Province, Indonesia. The first fern inventory had been conducted on this island, to identify the fern checklist as well as examined the morphology of their spores. Samples were collected from 2 subdistricts and 12 study sites, using exploration method. The spore specimens were coated using AU, before observation using Scanning Electron Microscopy (SEM). A total of 22 fern species are recorded from Bengkalis Islands. These species belong to 3 orders, i.e. Gleicheniales (1 species), Polypodiales (20 species) and Schizaeales (1 species). The spore characteristic indicated similar unity of spore, i.e. monad spore, with triangular, subtriangular, tetrahedral and reniform shape. Three basic types of spore have been observed, i.e. monolete, dilete, and trilete. The spore class observed in this study are small (22 ± 0.88 µm), medium (27.35 ± 1.45 to 47.85 ± 0.88 µm) and large (51.34 ± 1.83 to 53.8 ± 1.81 µm). The ornamentation of perisphore is the main character to distinguished species within one genus.

“…Subsequently forest and peat fires created haze problems (Collier 1979;Sabiham 2004). Peatland drainage led to land subsidence, frequent flooding and loss of agricultural land in coastal areas where the mineral soil is below sea level (Hooijer et al 2012;Sutikno et al 2017;Bassi et al 2020). This mirrors exactly the recent flooding experienced in the Food self-sufficiency strategies may benefit countries with large populations, high food insecurity, rich agricultural resources, and where the dominant staple food is traded globally by few suppliers (Clapp 2017).…”

Highlights• This brief reviews the interlinkages between food, nutrition and the environment in Indonesia, and the role of national food policies in addressing the challenges in these sectors.• While Indonesia is a mega-biodiverse country, nationally supported agricultural production programs tend to focus on a few high-value commodities, contributing to low dietary diversity.• Lessons from past food estate programs suggest that food system interventions that focus heavily on increasing monocropping, especially rice production, overlook the capacity of local people to develop their own food systems, while failing to provide healthy diets, and damaging the environment.• To move towards sustainable food systems, we argue that policies need to: focus on delivering healthy and diverse diets; support local food production practices that are environmentally sustainable; embrace local cultures and values; re-evaluate centralized and top-down policies; and avoid overly focusing on production of rice.• Policies that decentralize and localize food production can enhance resilience and the sustainability of food systems.

“…Laju abrasi di Pulau Rangsang dalam rentang tahun 1999-2014, berkisar antara 2,80 -12,28 meter per tahun, sementara laju akresi berkisar antara 0,20-8,21 meter per tahun (Hakim et al, 2014). Sementara laju abrasi di Pulau Bengkalis dalam medio 1988-2014 menunjukkan laju abrasi yang lebih tinggi lagi yaitu 32,75 meter per tahun (Sutikno et al, 2017). Tingkat abrasi yang tinggi pada ke dua pulau disebabkan karena sebagian wilayah pesisirnya berhadap langsung dengan perairan Selat Malaka, sehingga tidak terdapat pelindung dari pengaruh dinamika oseanografi yang dapat mempengaruhi garis pantai.…”

Mapping of coastline changes helps in coastal development and monitoring. The city of Dumai, on the east coast of Riau Province, has undergone significant and radical changes caused by the intervention of humans and nature over the past three decades. This study mapped and measured the rate of change of the coastline of Dumai City for 30 years. The Landsat (TM, and OLI) image series, 1990, 1999, 2008, and 2020 became a data source to generate coastlines through on-screen digitization techniques, then to study the temporal behavior of coastlines using the Digital Shoreline Analysis System (DSAS) and geographic information systems to describe the spatial and temporal variations of coastlines. The results showed that the coastline length during the observation ranged from 123,14 to 125,23 km, while the average accretion rate was 1.17 meters per year while the average abrasion rate was 2.04 meters per year. Those rates of change affected coastline expanded to the sea for 60,82 hectares and eroded 760,20 hectares coastline to the land.
