A review of science–policy interface for water governance in the Caspian Sea

Science and policy have been interlinked for decades and perform essential nexus conditions in the governing aspects of environmental scenarios.This review paper examines the present challenges in the science–policy interface in terms of water governance in the Caspian Sea and identifies effective conditions that may be used in the current context to enhance the mechanism.The evaluation of the science–policy link in the water policy of the Caspian Sea reveals a gap between knowledge producer and governance system,impeding the translation of scientific information into action.Complicated and context-dependent solutions make it challenging to establish effective science–policy processes in the Caspian Sea water governance settings.Establishing a common governing authority,implementing water and resource management regulations,and protecting the natural environment through legal frameworks are crucial steps to address these concerns and ensure sustainable development.Collaboration among coastal states is essential in environmental,economic,and social aspects of regional development.However,the lack of a comprehensive approach,coherent activities,and effective utilization of national and regional power has hindered efforts to halt the environmental degradation of the Caspian Sea.Local governments need to recognize their responsibility to protect and utilize the Caspian Sea for present and future generations,considering both environmental and human security.The interlinkage of the Caspian Sea water governance with the Organization for Economic Co-operation and Development(OECD)water governance principles offers a framework for policymakers to assess gaps and make necessary amendments to existing mechanisms.Effective science–policy interaction,engagement of diverse stakeholders,institutionalizing agreements,and addressing collective action issues are critical for successful water governance.

Rural Development Transformation and Social Governance from the Perspective of Specialization:A Case Study of Ruiling Village in Guangzhou City,China

The reorganization of the global production network and the increased mobility of urban-rural elements have accelerated the differentiation of rural spaces,resulting in a trend towards specialization in rural areas.This paper focuses on the concept of specialization,and takes a renowned bonsai specialized village in Guangzhou City,China as a typical case to explore its transformation and development process,action logic and coupling mechanism with the social governance.The results show that:1)the development of rural specialization in Ruiling Village is shaped by several key actors,such as local governments,grassroots organizations,villagers,social organizations,policies,markets and infrastructure.The transfer of these key actors and the reconstruction of actor-networks in different stages have an important influence on the transformation and realization of rural development goals.2)Through subjects-driven,organization management and resource connection,social governance supports the specialization of rural industrial organization,operation,technology and mode.The governance structure shifts from decentralization to networking,refinement and integration.A coupling community of social governance and specialization is created by the social governance system of‘local government-grassroots organizationseconomic cooperatives-villagers’,which links industries,industrial chains and cooperatives.3)Social governance integrates into the value chain extension process of rural specialized development with a central,multi-level organizational structure.It promotes the construction of the whole value chain through organizational planning,resource integration and image shaping,thus realizing the value,branding and organization of the industry,as well as the integration of rural sustainable development and governance mechanism.Social governance has a profound impact on the development of rural specialization in terms of subject,structure and mode,and participates in the construction of the whole value chain of rural areas.This paper provides a new perspective for understanding the coupling effect of social governance in the rural development transformation,and promotes the rural sustainable development and governance.

Blockchain Governance: The Development and Application of a Framework for Waqf Institutions

The effectiveness of waqf administration is impeded by poor management of assets,opacity,and unstandardized reporting.Blockchain is expected to solve these issues due to its ability to record and trace every transaction,allowing administrators to discharge their accountability to waqf stakeholders.While there have been numerous proposals for waqf blockchain,there is no explicit framework for the governance of blockchain in waqf institutions.We propose a governance of blockchain framework for waqf institutions based on IT governance dimensions and blockchain governance dimensions from the literature.The framework comprises three dimensions(formation and context,actors,and means of governance/decision making)that subsume eight sub-dimensions across three layers and three stages.We then apply the framework on a blockchain-based waqf organization to examine its usefulness.The framework is among the first to be designed for waqf institutions.

Impact of forest governance and enforcement on deforestation and forest degradation at the district level:A study in West Bengal State,India

According to the United Nations Environmental Programme(UNEP),the world loses 1.0×106hm2forest land through deforestation annually.About 1.6×106people who depend on forests for livelihood are negatively affected by deforestation and forest degradation.The paper attempts to study the impact of forest governance,enforcement and socio-economic factors on deforestation and forest degradation at the local level in West Bengal State,India.The study was based on questionnaire survey data during 2020–2021 collected from three western districts(Purulia,Bankura,and Paschim Medinipur)where deforestation and poverty rates are higher than other districts in West Bengal State.The total number of selected villages was 29,and the total sample households were 693.A stratified random sampling technique was used to collect data,and a questionnaire was followed.Forest governance and enforcement indices were constructed using United Nation Development Programme(UNDP)methodology and a step-wise logistic regression model was used to identify the factors affecting deforestation and forest degradation.The result of this study showed that four factors(illegal logging,weak forest administration,encroachment,and poverty)are identified for the causes of deforestation and forest degradation.It is observed that six indices of forest governance(rule of law,transparency,accountability,participation,inclusiveness and equitability,and efficiency and effectiveness)are relatively high in Purulia District.Moreover,this study shows that Purulia and Bankura districts follow medium forest governance,while Paschim Medinipur District has poor forest governance.The enforcement index is found to be highest in Purulia District(0.717)and lowest for Paschim Medinipur District(0.257).Finally,weak forest governance,poor socio-economic conditions of the households,and weak enforcement lead to the deforestation and forest degradation in the study area.Therefore,governments should strengthen law enforcement and encourage sustainable forest certification schemes to combat illegal logging.

Improving Land Governance in Nigeria:The Case of Compulsory Acquisition and Compensation Practice

This paper examines land policies on acquisition and compensation practice in Nigeria with the aim of minimizing conflicts in land acquisition and compensation.It further explains the implications of uncoordinated land allocations arising from informal transactions.The paper used self-administered questionnaires on all the fifteen(15)registered estate firms in the 2009 NIESV Directory in Benin City,Edo state to obtain information that helped to determine the fairness of compensation practice and causes of conflict in some communities in the state.The paper revealed that the compensation on acquired landed properties in Nigeria violated the principles of good governance as against what is obtainable in advanced countries.It also observed that inadequacy of compensation paid and delay in payment are the causes of conflict between the acquiring authorities and the affected community/people.The paper concluded that a review of land policies on acquisition and compensation will be a panacea for achieving the principles of good governance.

Barriers to Community Participation in Governance Standards Setting for Sustainable Mangrove Management in Lamu County

Mangrove management requires an all-inclusive community engagement for sustainability in protection and conservation of mangroves. Previously, community participation was not considered pivotal but the rapid degradation of mangroves has necessitated their participation. Despite much legislation enacted, there are still challenges hindering community participation in Lamu County and this paper seeks to highlight barriers perceived by the various stakeholders in mangrove management. The study used a mixed methods approach to answer both qualitative and quantitative research questions and a correlational research design to explore all variables. The study shows that only 60% of the respondents agreed that there is lack of enforcement in mangrove conservation through community participation. However, less than 50% agreed on the challenges of lack of good management in mangroves (46%), lack of implementation mechanisms on mangrove conservation (47%) and lack of consultation in decision-making processes for mangrove conservation (36%). This demonstrates that lack of enforcement is the greatest challenge to the implementation of standards for mangrove conservation.
