The current effort in Australia to increase the proportion of perennial vegetation in agricultural landscapes to manage dryland salinity presents opportunities to improve the viability of remnant vegetation and its dependant biota. At this intersection of ecology and agriculture, many questions arise concerning interpretations of biodiversity from the perspectives of landowners and conservationists, the conservation priorities in agricultural landscapes, and the role of ecological science in understanding the functional contribution of emerging perennial-plant based farming systems to the viability of the native biota. This paper provides the background for the four papers that follow, presented originally at a workshop at Rutherglen in Victoria in October 2003 to discuss the issue of biodiversity values in agricultural landscapes. It then puts forward an approach to research into the biodiversity value of perennial land use systems based on three principles; understanding regional conservation priorities, appreciating farm scale priorities and constraints from the perspective of the landholder, and identifying response functions to establish the role of revegetation in maintaining the viability of the native biota.

The main stages of the formation of ecological paradigms of environmental management are considered, the fundamental role of V.V. Dokuchaev ideas and the importance of following V.I. Vernadskiy works in their development are shown. The role of scientists of the Club of Rome in the development of the ideology of sustainable development and its controversial perception by the world scientific community is reflected. The analysis of the existing paradigms, in particular of the co-evolutionary paradigm, and its implementation in the theory and practice of adaptive-landscape farming systems is given. The priority tasks for its improvement are defined. Further prospects for its development are considered in the framework of the proposed constructive-biospheric paradigm of environmental management, which implies the creation of a network of agricultural landscapes (agricultural, water, land reclamation, agro-industrial, rural forestry, livestock, residential) in compliance with the ecological status of the territory. The grouping of ecological functions of the landscape and mechanisms of their transformation into socio-economic functions are considered as tools for landscape-ecological planning and design.

THIS book is a valuable historic record of the practices employed by land managers, government programs and community groups to ensure a place for nature in farming landscapes. Its strength lies in the 16 case studies of individual properties and the 14 examples of general approaches to integrating conservation into production systems. Those two very practical sections, plus another describing programs such as Landcare, carbon credits and offsetting, make up just under half the book. This practical, real world middle section is sandwiched between two sections that are quite different in tone and character to the sympathetic description of local heroes in the book’s heart. At the beginning are six chapters that introduce the concepts of landscape and community ecology to establish the scientific case for conservation. This includes analysis of types of farming systems, patterns of remnant vegetation distribution, and the functional properties of the agricultural matrix from the perspective of biodiversity. At the end are four chapters reflecting on the case studies and their implications. In both the introductory and concluding sections, the voice is that of the concerned ecologist, looking over the farm fence and wondering aloud ‘is this really going to be enough?’ Right towards the end is the warning that unless things change, “…the biodiversity train wreck lying ahead could exceed even our worse fears.”

The functioning of various agroecosystems is nowadays shaped by different farming systems, which may impair their functions, as well as being beneficial to them. The benefits include ecosystem services, defined as economic and noneconomic values gained by humans from ecosystems, through supporting soil formation and nutrient circulation, and the impact of agriculture on climate and biodiversity. Their mutual flow and various disturbances depend on the agroecosystem’s management method, which is associated with the type of management of agricultural land (AL) in individual farms. This paper raises a problem of transformation in the structure of three main farming systems in Poland, in 2004–2018, in relation to the implementation of 16 selected ecosystem services and their scale. Special attention was given to organic farming, as the most environmentally friendly and sustainable. The analysis demonstrates the increase in ALs in that type of production during the analyzed period of time. Disparities of transformation associated with the type of agricultural system were noticeable at the regional level, which were presented in 16 Polish voivodeships. The results of the analysis confirm that the organic system, which is an important carrier of various ecosystem services, gained a stable position. Moreover, areas with integrated farming still do not exceed 0.5% of total agricultural lands in such voivodeships. The analysis of factors influencing the deterioration or disappearance of selected environmental services characterizing agricultural systems indicates the need to depart from an intensive conventional management system.

In promoting biodiversity conservation and ecosystem service capacity, landscape connectivity is considered a critical feature to counteract the negative effects of fragmentation. Under a Green Infrastructure (GI) perspective, this is especially true in rural and peri-urban areas where a high degree of connectivity may be associated with the enhancement of agriculture multifunctionality and sustainability. With respect to GI planning and connectivity assessment, the role of dispersal traits of tree species is gaining increasing attention. However, little evidence is available on how to select plant species to be primarily favored, as well as on the role of landscape heterogeneity and habitat quality in driving the dispersal success. The present work is aimed at suggesting a methodological approach for addressing these knowledge gaps, at fine scales and for peri-urban agricultural landscapes, by means of a case study in the Metropolitan City of Rome. The study area was stratified into Environmental Units, each supporting a unique type of Potential Natural Vegetation (PNV), and a multi-step procedure was designed for setting priorities aimed at enhancing connectivity. First, GI components were defined based on the selection of the target species to be supported, on a fine scale land cover mapping and on the assessment of land cover type naturalness. Second, the study area was characterized by a Morphological Spatial Pattern Analysis (MSPA) and connectivity was assessed by Number of Components (NC) and functional connectivity metrics. Third, conservation and restoration measures have been prioritized and statistically validated. Notwithstanding the recognized limits, the approach proved to be functional in the considered context and at the adopted level of detail. Therefore, it could give useful methodological hints for the requalification of transitional urban–rural areas and for the achievement of related sustainable development goals in metropolitan regions.

UNESCO’s world heritage program aims to protect sites of cultural and natural heritage worldwide. Issues of local communities and well-being have been given increasing attention by heritage conservation scholars, but a systemic review of UNESCO guidelines has not been performed. Here, we examine the evolution of the ‘Operational Guidelines for the Implementation of the World Heritage Convention’, documents representing the heritage conservation policies of UNESCO over the period 1994–2019. Using keyword analysis and document analysis, the findings show evidence of an increasing emphasis on local communities, growing primarily since 2005. However, the theme of well-being only first emerged in the operational guidelines in 2019. Political, economic, and environmental challenges idiosyncratic to specific places often complicate the role of local communities and well-being in heritage conservation priorities. Future research should investigate the potential implementation and implications of these changes for the guidelines at specific UNESCO world heritage sites.

The International Institute of Tropical Agriculture (IITA) has applied the concept of ‘circular bioeconomy’ to design solutions to address the degradation of natural resources, nutrient-depleted farming systems, hunger, and poverty in sub-Saharan Africa (SSA). Over the past decade, IITA has implemented ten circular bioeconomy focused research for development (R4D) interventions in several countries in the region. This article aims to assess the contributions of IITA’s circular bioeconomy focused innovations towards economic, social, and environmental outcomes using the outcome tracking approach, and identify areas for strengthening existing circular bioeconomy R4D interventions using the gap analysis method. Data used for the study came from secondary sources available in the public domain. Results indicate that IITA’s circular bioeconomy interventions led to ten technological innovations (bio-products) that translated into five economic, social, and environmental outcomes, including crop productivity, food security, resource use efficiency, job creation, and reduction in greenhouse gas emissions. Our gap analysis identified eight gaps leading to a portfolio of five actions needed to enhance the role of circular bioeconomy in SSA. The results showcase the utility of integrating a circular bioeconomy approach in R4D work, especially how using such an approach can lead to significant economic, social, and environmental outcomes. The evidence presented can help inform the development of a framework to guide circular bioeconomy R4D at IITA and other research institutes working in SSA. Generating a body of evidence on what works, including the institutional factors that create enabling environments for circular bioeconomy approaches to thrive, is necessary for governments and donors to support circular bioeconomy research that will help solve some of the most pressing challenges in SSA as populations grow and generate more waste, thus exacerbating a changing climate using the linear economy model.

Pasture-based livestock systems, often located in High Value Nature farmland areas, hold the greatest potential to deliver public goods across European agricultural systems. They play an important role in preserving agricultural landscapes, farmland biodiversity, cultural heritage, and in sustaining rural development. However, many of these functions are ignored in evaluation frameworks because public goods do not have market price and are often ignored in policy design, so farmers do not get the appropriate incentives to provide them. Different conceptual frameworks can be utilized to evaluate the multiple functions or services of these systems: Multifunctional Agriculture, Ecosystem Services, and Total Economic Value. We analyze the common characteristics of these concepts (e.g. they place human benefits and societal demands at the core of their definitions), their specificities (e.g. use of different units of analysis and spatial-temporal scales), and how they can be embedded in the wider concept of sustainability. Finally, we illustrate how the different concepts can be combined to evaluate pasture-based livestock farming systems from a socio-cultural and economic perspective. The public goods (ecosystem services) provided by representative case studies in Mediterranean and Nordic regions are quantified (also in monetary terms) under different environmental/policy scenarios. The results show that there is a clear underestimation of the socio-cultural and economic values of ecosystem services provided by these farming systems. They also show that the social welfare loss linked to further abandonment of livestock farming, and the associated environmental degradation, is very large. From a societal perspective, it is necessary to jointly measure the biophysical, socio-cultural and monetary values of ecosystem services (market and nonmarket) in order to promote the sustainability of pasture-based livestock systems.

The economic and socio-political interactions between countries can have major impacts on transboundary conservation decisions and outcomes. Here, we examined for 14 Western Indian Ocean (WIO) continental and island nations the extent of their marine coral reef species, fisheries and marine protected areas (MPAs), in the context of their geopolitical and socio-economic connections. We also examined the role of external countries and organisations in collaboration within the region. We found large variation between the different countries in their protected area size, and management, which result from different interests in establishing the MPAs, ranging from fisheries management, biodiversity conservation to asserting sovereignty claims. Seventy-four per cent of the 154 MPAs in the region belong to island nations; however, the largest MPAs in the WIO were established by European powers, and include Mayotte and Glorioso Islands (France) and Chagos (UK). While the majority of MPAs are managed by individual countries, between-country collaboration within and outside the region is key if the aim is to achieve effective conservation of ecosystems and species across the island and mainland nations in the region. This may be advanced by creating transboundary MPAs and by regional conservation investment by external powers that benefit from the region’s resources.
