Recent nam ook het aantal meldingen van infecties van wilde zoogdieren toe. Inmiddels gaat het om meer dan 30 soorten. In nertsen en diverse zeezoogdieren was er zelfs sprake van grootschalige overdracht tussen zoogdieren. Deze bevindingen benadrukken dat het virus de mogelijkheid heeft om zich aan te passen aan zoogdieren en overdraagbaar te worden. Gelukkig wordt op dit moment het risico voor mensen nog niet hoog ingeschat.

Tijdens deze bijeenkomst lichten de sprekers recente ontwikkelingen toe in de HPAI-uitbraken in wilde vogels, pluimvee, mensen en andere zoogdieren, met focus op Nederland. Daarbij staan ze stil bij de interventie-opties die beschikbaar zijn om de gezondheid van dieren en mensen te borgen, en de moeilijkheden rondom deze interventie-opties.

Het H5N1-vogelgriepvirus heeft inmiddels de sprong gemaakt van vogels en pluimvee naar diverse zoogdieren en heeft zich ook verspreid naar andere delen van de wereld. Wat zijn de laatste ontwikkelingen rond vogelgriep? Welke opties zijn er om de gezondheid van dieren en mensen te borgen, en wat zijn hierbij de risico’s?

This talk will discuss McGregor's doctoral research which focused on three main topics: 1) a novel, NRT detection algorithm that was created to explicitly assess multiple spectra of trade-offs; 2) landscape processes that were incorporated into the algorithm using a Bayesian approach; and 3) an expansion of the methodology used to develop a continuously-improving model by integrating input from in-situ users.

Comparing Europe and America
The papers in this special issue explore the archaeology and historical ecology of wetland environments in various parts of Europe and northern America. These environments all have in common that they have been reclaimed at one or multiple moments in their history, and that these reclamations have shaped the subsequent development of the landscape and environment.

Besides showing the historical depth and variability of wetland reclamation, the papers also reflect upon the need for wetland environments globally to be restored in order to combat two of the key challenges of the Anthropocene – climate change and biodiversity declines.

This is the contribution by dr.Tymon de Haas and dr. Mans Schepers, in which they compare the diachronic development of two reclaimed wetland landscapes in the Netherlands (de Onlanden in Groningen) and Italy (the Pontine Plain):

Wetland reclamation has occurred under diverse geographic and socio-political conditions. A single reclamation event however, forms only one step in the evolution of what we refer to as reclamation landscapes. This paper assesses how interacting physical geographical, cultural and biological processes shape the landscape diachronically. Using a triangular model, we compare two wetland landscapes: the Pontine marshes in central Italy, reclaimed as part of Rome’s early Imperial expansion; and the Onlanden area in the northern Netherlands, reclaimed by emergent state societies in the Middle Ages. Reclamation turned out not fully resilient from a cultural perspective in both cases, as physical geographical and biological processes continued to raise challenges in both reclamation landscapes. It is argued that the triangular model offers potential to systematically explore the drivers behind landscape evolution comparatively. A better understanding of such drivers may in turn improve current landscape management policies, including rewilding efforts.

The Reclamation Landscapes of the Onlanden (Northern Netherlands) and Pontine Marshes (Central Italy): A Short Introduction
The two reclamation landscapes that are object of study are the Pontine marshes in central Tyrrhenian Italy, and the Onlanden in the northern Netherlands (Figure 2). Both areas are characterized by an extensive and ongoing research history, which includes various types of archaeological, palaeo-environmental, and geological studies. Both these areas specifically serve as examples of well-studied reclamation landscapes and we heavily rely on previously published work by ourselves and others for this paper. For more detailed information, as well as the source data underlying various aspects discussed here, we refer to the original sources.

The Onlanden are located in the Northern Netherlands, on the border between the provinces of Groningen and Drenthe. The area is divided in a number of sub-regions, largely determined by its reclamation history. In this contribution, we will primarily focus on the area known as the Roderwolderpolder. This relatively low-lying area has a diverse ecological history, but has been ‘wet’ in varying, and relevant, degrees throughout history. The southern part of the area consists primarily of peat soils. These occur in the Northern area as well, but there these have been covered by younger, clay sediments. The hydrological and pedological conditions of the area explain the name Onlanden, which literally translates to ‘bad lands’. No actual settlements developed within the reclaimed area, but villages do occur on higher sandy outcrops around it. The most important of these is the city of Groningen, which over time has expanded significantly and now borders the area. The expansion of the Medieval town of Groningen probably triggered the intensification of the exploitation and reclamation of the Onlanden in the Middle Ages. It has long been known that numerous raised homesteads or small dwelling mounds occur in the area that date back to this period. A major field-work project focusing on the aforementioned Roderwolderpolder was carried out from 2008 to 2011, resulting in an extensive edited volume that is the basis for the present analysis (Nicolay Citation2018a).1This is published in Dutch, but English summaries are provided for all chapters. This project followed the intended transformation of the area from an agricultural area, into an area used simultaneously for (wetland) nature development and water retention.
