Management Sustainability - past present and future trends

Research related to sustainable management is rapidly increasing in quantity and is found in divergent literature and disciplines. Now is the time to offer a comprehensive review that identifies, synthesizes, and integrates previous research and highlights knowledge gaps and the way forward. This methodical literature search helped systematize 86 articles in the Scopus database published by 2018. Using a systematic and in-depth content analysis using bibliometric techniques, the authors reviewed the articles and identified the main theories used and the methodological orientations in these. articles. This review helps to identify significant knowledge gaps in terms of theoretical orientation and core content. The main contributions of this paper are: to outline and summarize a multilevel analysis of emerging sustainable management literature; integrate and extract potential theoretical contributions in this field; and indicate directions for future research.

Drivers of Long-Term Land-Use Pressure in the Merguellil Wadi, Tunisia, Using DPSIR Approach and Remote Sensing

Increasing land use pressure is a primary force for degradation of agricultural areas. The drivers for these pressures are initiated by a series of interconnected processes. This study presents a novel methodology to analyze drivers of changing land use pressure and the effects on society and landscape. The focus was on characterizing these drivers and relate them to land use statistics obtained from geospatial data from the important semiarid Merguellil Wadi between 1976 and 2016. Cause-and-effect relationships between different drivers of land use change were analyzed using the DPSIR approach. Results show that during the 40-year period cultivated land increased and wetland areas decreased substantially. Drivers for change were pressure from economic development, cultivation practices, and hydro-agricultural techniques. This leads to stress on water and soil resulting in soil erosion, poverty increase, and rural exodus. We show that hydro-agricultural techniques adapted to the semiarid climate, allocation of land property rights, resource allocation, and improved marketing of agricultural products can help rural residents to diversify their economy, and thus better preserve the fragile semiarid landscape. Results of this study can be used to ensure sustainable management of water and soil resources in areas with similar climate and socio-economic conditions.

Sustainable Management of Environmental Risks in Agricultural Production: Ensuring the Right to Food

The current research is about the sustainable management of environmental risks in agricultural production to ensure the right to food. In a globalized world, agricultural production is determined by external economic, environmental, social, legal, and political factors, as well as internal factors depending on each State’s conditions. Environmental risk factors, particularly, the growing climate change and its negative effects or the occurrence of a global pandemic, restrict agricultural industry development and create uncertainty in guaranteeing people’s right to food. Agricultural production is the first right to food material guarantee. Ensuring agricultural production is ensuring people’s right to food, their food security or at least the minimum necessary to avoid hunger. The aim is to systematize environmental risks sustainable management concepts and characteristics applied in agricultural production to guarantee the right to food. The environmental risk’s sustainable management entails an efficient use of financial and economic resources in agricultural production to prevent or reduce the environmental risk identified impact. The research establishes some general points of environmental risks sustainable management in agricultural production to guarantee the right to adequate food. The following research methods and techniques were selected: the theoretical-legal and document analysis.

Sustainable management of populations impacted by harvesting and climate change

The sustainable use of natural resources is critical for addressing the global challenges of today. Strategies for sustainable harvesting need to consider not only harvested species, but also other non-harvested species interacting with them in the same ecosystem. In addition, environmental variation needs to be considered, with climate change currently being one of the main sources of this variation. Understanding the consequences of complex interactions between different drivers and processes affecting dynamics of species and ecosystems across spatial scales requires large-scale integrative research projects. The Norwegian research initiative “Sustainable management of renewable resources in a changing environment: an integrated approach across ecosystems” (SUSTAIN) was launched to fill knowledge gaps related to the sustainable management of populations and ecosystems experiencing climate change. SUSTAIN investigated terrestrial, marine and freshwater ecosystems in boreal and Arctic regions, using both theoretical developments and empirical analyses of long-term data. This Climate Research Special contains both synthesis articles and original research exemplifying some of the approaches used in SUSTAIN. In this introduction we highlight 4 key topics addressed by SUSTAIN: (i) population structure, (ii) interactions between species, (iii) spatial processes, and (iv) adaptive management. These topics are fundamental to the understanding of harvested species from an ecosystem perspective, and to ecosystem-based management approaches, which we are striving to work towards.

The Potential of Esteya spp. for the Biocontrol of the Pinewood Nematode, Bursaphelenchus xylophilus

The pinewood nematode (PWN), Bursaphelenchus xylophilus, is the causal agent of pine wilt disease (PWD) and a quarantine organism in many countries. Managing PWD involves strict regulations and heavy contingency plans, and present climate change scenarios predict a spread of the disease. The urgent need for sustainable management strategies has led to an increasing interest in promising biocontrol agents capable of suppressing the PWN, like endoparasitic nematophagous fungi of the Esteya genus. Here, we review different aspects of the biology and ecology of these nematophagous fungi and provide future prospects.
