Built heritage constitutes an invaluable asset to be treasured and wisely managed in order to avoid loss of place identity, cultural and social degradation and loss of leisure and tourism opportunities. The present paper focuses on the modern built heritage of the Thessaly Region (Greece), giving special emphasis to the “konakia” monuments built during the late 19th and early 20th century that were once used as residences by the big landowners of the Thessalian agricultural plain (“tsiflikia”). Field research conducted, as well as a survey of secondary data, revealed that only fifteen (15) “konakia” remain in Thessaly, equally dispersed in Larisa, Trikala and Karditsa Prefectures. Given their use, all of the “konakia” are found within—or in the vicinity of—agricultural land and settlements. Most of them present severe signs of abandonment, while only four (4) of them are in use (either as second-homes or as spaces with cultural and administrative use). Starting in 1979 (until 2005), with the exception of the Averof “konakia”, all of the rest have been designated as part of the modern built heritage of Greece. Considering these facts—and that most of such properties are private—the paper proposes a six (6) step methodology, for their wise management and integration in the spatial and cultural landscape of Thessaly: (1) Selection of the proper type of (re)use of the monument(s), (2) selection (or reconsideration) of the protection status and zoning, (3) identification of the urban regeneration interventions, (4) introduction of the necessary amendments to the urban/local plan, (5) selection of the proper financial tools and (6) selection of the proper marketing strategy. The paper concludes by highlighting the need to address the “konakia” as a set of monuments, to achieve stakeholders’ engagement and local community involvement, without undermining either protection status or the private rights of owners over these cultural properties.

Abstract. In steep landscapes, river incision sets the pace of landscape evolution. Transport of coarse sediment controls incision by evacuating material delivered to river channels by landslides. However, large landslide-derived boulders that impede bedrock erosion are immobile even in major runoff-driven floods. Glacial lake outburst floods (GLOFs) mobilize these boulders and drive incision, yet their role in regional-scale erosion is poorly understood, largely because of their rarity. Here, we find a topographic signature consistent with widespread GLOF erosion in the Nepal Himalaya. In rivers with glaciated headwaters that generate GLOFs, valleys stay narrow and relatively free of sediment, with bedrock often exposed to erosion. In turn, tributaries to these valleys are steep, allowing less efficient erosional regimes to keep pace with GLOF-driven incision. Where GLOFs are less frequent, valleys are more alluviated and incision stalls. Our results suggest the extent of headwater glaciation may play an important role in erosion of Himalayan river valleys and deserves more attention in future work.

Abstract. Glacial lake outburst floods (GLOFs) pose a significant threat to downstream communities and infrastructure due to their potential to rapidly unleash stored lake water. The most common triggers of these GLOFs are mass movement entering the lake and/or the self-destruction of the terminal moraine due to hydrostatic pressures or a buried ice core. This study initially uses previous qualitative and quantitative assessments to understand the hazards associated with eight glacial lakes in the Nepal Himalaya that are widely considered to be highly dangerous. The previous assessments yield conflicting classifications with respect to each glacial lake, which spurred the development of a new holistic, reproducible, and objective approach based solely on remotely sensed data. This remote hazard assessment analyzes mass movement entering the lake, the stability of the moraine, and lake growth in conjunction with a geometric GLOF to determine the downstream impacts such that the present and future risk associated with each glacial lake may be quantified. The new approach is developed within a hazard, risk, and management action framework with the aim that this remote assessment may guide future field campaigns, modeling efforts, and ultimately risk-mitigation strategies. The remote assessment was found to provide valuable information regarding the hazards faced by each glacial lake and results were discussed within the context of the current state of knowledge to help guide future efforts.
