Fire has a long history in Australia and is a key driver of vegetation dynamics in the tropical savanna ecosystems that cover one quarter of the country. Fire reconstructions are required to understand ecosystem dynamics over the long term but these data are lacking for the extensive savannas of northern Australia. This paper presents a multiproxy palaeofire record for Marura sinkhole in eastern Arnhem Land, Northern Territory, Australia. The record is constructed by combining optical methods (counts and morphology of macroscopic and microscopic charcoal particles) and chemical methods (quantification of abundance and stable isotope composition of pyrogenic carbon by hydrogen pyrolysis). This novel combination of measurements enables the generation of a record of relative fire intensity to investigate the interplay between natural and anthropogenic influences. The Marura palaeofire record comprises three main phases: 4600–2800 cal BP, 2800–900 cal BP and 900 cal BP to present. Highest fire incidence occurs at ~4600–4000 cal BP, coinciding with regional records of high effective precipitation, and all fire proxies decline from that time to the present. 2800–900 cal BP is characterised by variable fire intensities and aligns with archaeological evidence of occupation at nearby Blue Mud Bay. All fire proxies decline significantly after 900 cal BP. The combination of charcoal and pyrogenic carbon measures is a promising proxy for relative fire intensity in sedimentary records and a useful tool for investigating potential anthropogenic fire regimes.

Fire regimes in many north Australian savanna regions are today characterised by frequent wildfires occurring in the latter part of the 7-month dry season. A fire management program instigated from 2005 over 24 000 km2 of biodiversity-rich Western Arnhem Land aims to reduce the area and severity of late dry-season fires, and associated greenhouse gas emissions, through targeted early dry-season prescribed burning. This study used fire history mapping derived mostly from Landsat imagery over the period 1990–2009 and statistical modelling to quantify the mitigation of late dry-season wildfire through prescribed burning. From 2005, there has been a reduction in mean annual total proportion burnt (from 38 to 30%), and particularly of late dry-season fires (from 29 to 12.5%). The slope of the relationship between the proportion of early-season prescribed fire and subsequent late dry-season wildfire was ~–1. This means that imposing prescribed early dry-season burning can substantially reduce late dry-season fire area, by direct one-to-one replacement. There is some evidence that the spatially strategic program has achieved even better mitigation than this. The observed reduction in late dry-season fire without concomitant increase in overall area burnt has important ecological and greenhouse gas emissions implications. This efficient mitigation of wildfire contrasts markedly with observations reported from temperate fire-prone forested systems.

The author examines the “In Thee rejoiceth” icons as visual sources that make it possible to reconstruct the ideal model of medieval society in the Moscow culture of the late 15th and early 16th centuries. This icon type, which includes the scenes of “Human race” collective praying to the Mother of God, is of Russian origin. Unlike other works of that time typologically close to it (“The Intercession”, “The Congregation of Our Lady”, “The Congregation of All Saints”, etc.), the “In Thee rejoiceth” icons demonstrate a historical connection to religious and socio-cultural facts of the Muscovy state. They clearly express the idea of Muscovy enjoying special patronage of the Mother of God, whose cult was actively developed in Moscow, the city that, as was believed at the Grand Dukes’ court, inherited the traditions and the spiritual authority of Constantinople. The depiction of the “Human race” in the “In Thee rejoiceth” icons can be viewed as a metaphorical image of the capital city community consisting of different groups of clergy and laity. This image corresponded to the ideas of the authorities and the population of the Russian state that existed under Ivan III and Vasili III.

For much of the twentieth century UK public policy has been based on a strong centralist, rationalist and managerialist framework. This orientation was significantly amplified by New Labour in the 1990s and 2000s, leading to the development of ‘evidence-based policy making’ (EBPM) and the ‘audit culture’ – a trend that looks set to continue under the current government. Substantial criticisms have been raised against the targeting/audit strategies of the audit culture and other forms of EBPM, particularly in complex policy areas. This article accepts these criticisms and argues that in order to move beyond these problems one must not only look at the basic foundation of policy strategies, but also develop practical alternatives to those strategies. To that end, the article examines one of the most basic and common tools of the targeting/audit culture, the aggregate linear X-Y graph, and shows that when it has been applied to UK education policy, it leads to: (1) an extrapolation tendency; (2) a fluctuating ‘crisis–success' policy response process; and (3) an intensifying targeting/auditing trend. To move beyond these problems, one needs a visual metaphor which combines an ability to see the direction of policy travel with an aspect of continual openness that undermines the extrapolation tendency, crisis–success policy response and targeting/auditing trend. Using a general complexity approach, and building on the work of Geyer and Rihani, this article will attempt to show that a ‘complexity cascade’ tool can be used to overcome these weaknesses and avoid their negative effects in both education and health policy in the UK.

The paper examines the application of the ecological thresholds concept to fire management issues concerning fire-sensitive vegetation types associated with the remote, biodiversity-rich, sandstone Arnhem Plateau, in western Arnhem Land, monsoonal northern Australia. In the absence of detailed assessments of fire regime impacts on component biota such as exist for adjoining Nitmiluk and World Heritage Kakadu National Parks, the paper builds on validated 16-year fire history and vegetation structural mapping products derived principally from Landsat-scale imagery, to apply critical ecological thresholds criteria as defined by fire regime parameters for assessing the status of fire-sensitive habitat and species elements. Assembled data indicate that the 24 000 km2 study region today experiences fire regimes characterised generally by high annual frequencies (mean = 36.6%) of large (>10 km2) fires that occur mostly in the late dry season under severe fire-weather conditions. Collectively, such conditions substantially exceed defined ecological thresholds for significant proportions of fire-sensitive indicator rain forest and heath vegetation types, and the long-lived obligate seeder conifer tree species, Callitris intratropica. Thresholds criteria are recognised as an effective tool for informing ecological fire management in a variety of geographic settings.
