The COVID-19 pandemic has caused global disruption, with the emergence of this and other pandemics having been linked to habitat encroachment and/or wildlife exploitation. High impacts of COVID-19 are apparent in some countries with large tropical peatland areas, some of which are relatively poorly resourced to tackle disease pandemics. Despite this, no previous investigation has considered tropical peatlands in the context of emerging infectious diseases (EIDs). Here, we review: (i) the potential for future EIDs arising from tropical peatlands; (ii) potential threats to tropical peatland conservation and local communities from COVID-19; and (iii) potential steps to help mitigate these risks. We find that high biodiversity in tropical peat-swamp forests, including presence of many potential vertebrate and invertebrate vectors, combined, in places, with high levels of habitat disruption and wildlife harvesting represent suitable conditions for potential zoonotic EID (re-)emergence. Although impossible to predict precisely, we identify numerous potential threats to tropical peatland conservation and local communities from the COVID-19 pandemic. This includes impacts on public health, with the potential for haze pollution from peatland fires to increase COVID-19 susceptibility a noted concern; and on local economies, livelihoods and food security, where impacts will likely be greater in remote communities with limited/no medical facilities that depend heavily on external trade. Research, training, education, conservation and restoration activities are also being affected, particularly those involving physical groupings and international travel, some of which may result in increased habitat encroachment, wildlife harvesting or fire, and may therefore precipitate longer-term negative impacts, including those relating to disease pandemics. We conclude that sustainable management of tropical peatlands and their wildlife is important for mitigating impacts of the COVID-19 pandemic, and reducing the potential for future zoonotic EID emergence and severity, thus strengthening arguments for their conservation and restoration. To support this, we list seven specific recommendations relating to sustainable management of tropical peatlands in the context of COVID-19/disease pandemics, plus mitigating the current impacts of COVID-19 and reducing potential future zoonotic EID risk in these localities. Our discussion and many of the issues raised should also be relevant for non-tropical peatland areas and in relation to other (pandemic-related) sudden socio-economic shocks that may occur in future.

Tropical peatlands such as Ghana’s Greater Amanzule peatland are highly valuable ecosystems and under great pressure from anthropogenic land use activities. Accurate measurement of their occurrence and extent is required to facilitate sustainable management. A key challenge, however, is the high cloud cover in the tropics that limits optical remote sensing data acquisition. In this work we combine optical imagery with radar and elevation data to optimise land cover classification for the Greater Amanzule tropical peatland. Sentinel-2, Sentinel-1 and Shuttle Radar Topography Mission (SRTM) imagery were acquired and integrated to drive a machine learning land cover classification using a random forest classifier. Recursive feature elimination was used to optimize high-dimensional and correlated feature space and determine the optimal features for the classification. Six datasets were compared, comprising different combinations of optical, radar and elevation features. Results showed that the best overall accuracy (OA) was found for the integrated Sentinel-2, Sentinel-1 and SRTM dataset (S2+S1+DEM), significantly outperforming all the other classifications with an OA of 94%. Assessment of the sensitivity of land cover classes to image features indicated that elevation and the original Sentinel-1 bands contributed the most to separating tropical peatlands from other land cover types. The integration of more features and the removal of redundant features systematically increased classification accuracy. We estimate Ghana’s Greater Amanzule peatland covers 60,187 ha. Our proposed methodological framework contributes a robust workflow for accurate and detailed landscape-scale monitoring of tropical peatlands, while our findings provide timely information critical for the sustainable management of the Greater Amanzule peatland.

The Many

The globalization of the economy encourages massive population displacements and inevitably generates a cosmopolitization of societies. This leads to concern, misunderstanding and rejection. The most vulnerable social groups in society can perceive the population as intruders and enemies in social competition. Undoubtedly, the extreme spatial instability of fishery resources is among the many factors affecting migration dynamics. Various reasons for the mobility of fishermen are relevant around this concept. These include aspect related to traditions, to the capitalisation of activity, to technological innovations, and to innovation exchanges concerning the location of fish stocks. This article reflects on spatial increase of fishermen’s. The analyse are part of the paradigm of the sustainable management of common renewable resources, in particular fishery resources. It presents three lines of analysis: the reason for mobility; the choice of destination; and are the integration into host units.

This paper highlights the lessons of using adaptive learning in community forestry that effectively help to resolve forest based conflicts in Terai region of Nepal. The paper is based on a three-year action research carried out in Terai. Qualitative methods including participatory rural appraisal tools and documentation of engaged action and reflections were used. Methods and tools that largely fall under adaptive learning were deployed. The field data was complemented by review of secondary data and literature on environmental history of Terai. We found that policies on land and forest in Terai for the last fifty years have induced and aggravated conflicts over access and control between state and communities and also within diverse groups of local communities. These conflicts have had serious negative impacts on sustainable management of forests and on local people’s livelihoods, particularly resource poor and landless people. Centralised and bureaucratic approaches to control forest and encroachment have largely failed. Despite investing millions of Rupees in maintaining law and order in forestlands, the problem continues to worsen often at the cost of forests and local communities. We found that transferring management rights to local communities like landless and land poor in the form of community forestry (CF) has induced strong local level collective action in forest management and supported local livelihoods. Moreover, adding adaptive learning, as a methodological tool to improve governance and enhance local level collective action significantly improves the benefit of CF. It implies that a major rethinking is needed in the current policies that have often led to hostile relationships with the local inhabitants- particularly the illegal settlers. Instead, transferring forest rights to local communities and supporting them through technical aspects of forest management will strengthen local initiatives towards sustainable management of forests.

The basic principle of Pro Silva silviculture is to be multifunctional and to seek to combine into a harmonious whole all the benefits provided by the forest. It is thus a management system constantly adapted to follow the evolution of different needs and requirements. On the occasion of the International Year of Biodiversity, it is here explained why this form of management meets in an optimal manner the interests of biodiversity without however pushing into the background the other functions, in particular carbon management. Intrinsically it corresponds to the principles of sustainable management, maintaining the balance between economic, social and ecological interests.
