Assessing the effects of different land use scenarios on subsequent changes in ecosystem service has great implications for sustainable land management. Here, we designed four land use/land cover (LULC) scenarios, such as business-as-usual development (BAUD), economic development priority (EDP), ecological protection priority (EPP), and afforestation development priority (ADP), through a Cellular Automata-Markov (CA-Markov) model, and their effects on ecosystem service values (ESVs) were predicted, using historical LULC maps and ESV coefficients of the Lower Meghna River Estuary, Bangladesh. Findings revealed that agricultural and mangrove forest lands experienced the greatest decreases, while rural and urban settlement land had the greatest increases, leading to a total ESV decrease of US$105.34 million during 1988-2018. The scenario analysis indicated that ESV in 2038 would also decrease by US$41.37 million and US$16.38 million under the BAUD and EDP scenarios, respectively, while ESV will increase by US$60.61 million and US$130.95 million under the EPP and ADP scenarios, respectively. However, all the future land use scenarios will lead to 1.65%, 10.21%, 7.58%, and 6.75% gaps in total food requirements, respectively. Hence, from the perspective of maximizing ESVs and minimizing the trade-offs in food gaps, the ADP scenario could be the optimal land management policy for the studied landscape.

Land use and climate change exert pressure on ecosystems and threaten the sustainable supply of ecosystem services (ESS). In Southeast-Asia, the shift from swidden farming to permanent cash crop systems has led to a wide range of impacts on ESS. Our study area, the Nabanhe Reserve in Yunnan province (PR China), saw the loss of extensive forest areas and the expansion of rubber (Hevea brasiliensis Müll. Arg.) plantations. In this study, we model water yield and sediment export for a rubber-dominated watershed under multiple scenarios of land use and climate change in order to assess how both drivers influence the supply of these ESS. For this we use three stakeholder-validated land use scenarios, varying in their degree of rubber expansion and land management rules. As projected climate change varies remarkably between different climate models, we combined the land use scenarios with datasets of temperature and precipitation changes, derived from nine General Circulation Models (GCMs) of the Fifth Assessment Report of the IPCC (Intergovernmental Panel on Climate Change) in order to model water yield and sediment export with InVEST (Integrated Valuation of Ecosystem Services and Trade-offs). Simulation results show that the effect of land use and land management decisions on water yield in Nabanhe Reserve are relatively minor (4% difference in water yield between land use scenarios), when compared to the effects that future climate change will exert on water yield (up to 15% increase or 13% decrease in water yield compared to the baseline climate). Changes in sediment export were more sensitive to land use change (15% increase or 64% decrease) in comparison to the effects of climate change (up to 10% increase). We conclude that in the future, particularly dry years may have a more pronounced effect on the water balance as the higher potential evapotranspiration increases the probability for periods of water scarcity, especially in the dry season. The method we applied can easily be transferred to regions facing comparable land use situations, as InVEST and the IPCC data are freely available.

PurposeIn geopolitical conflict zones, the phenomenon of abandonment often correlates with challenges of legal definitions and ownership status. The abandoned properties in conflict zones share similar characteristics with what is commonly known as a brownfield site. However, due to the nature of geopolitical conflict zones, which is mixed with people and sentiments other than technical challenges, the usual solutions to the brownfield question, cannot provide enough tools to deal with the land management of areas engulfed in conflicts. This paper, therefore, aims to discuss and propose a land-use typology that describes abandoned properties in a geopolitical context.Design/methodology/approachThe proposed land-use typology serves as the main conceptual framework that integrates the sustainable brownfield regeneration approach with social theories of space and place. As an inductive research approach, this conceptual framework brought the fundamental and comparative literature on brownfield regeneration to support the main argument related to the similarities and challenges of the regeneration of abandoned properties in conflict zones. The approach used in this paper addresses the broader consideration of land management in geopolitical contexts and urban conflict zones that considers the relationship of exercise of extreme power over space.FindingsThe findings highlight an insufficient understanding of the origin of the property problems in geopolitical conflict zones, especially after a power struggle, producing significant land management issues. In a geopolitical context, urban planners and economists' perspective on definitions of space and place defined by maps, GIS data sets, Excel and other similar tools may not bring any practical or long-term solution to the land management challenges. The study suggests that dealing with abandoned properties and regeneration plans in conflict zones requires identifying and evaluating geo-political, geo-social, geo-economic characteristics of the area before any further action.Practical implicationsThis paper's findings are of particular interest to decision-makers and conflict stakeholders in geopolitical conflict zones, such as local governments, policymakers and peacekeeping agencies. The findings of this research can clarify and help them have an alternative understanding of the space engulfed in the conflict, other than a technocratic, mapping, GIS, statistical way of understanding and approaches to the complex aspect of a space.Originality/valueThis paper's conceptual framework provides a value-added contribution to the literature on land management in conflict zones by taking the reader's attention to the origin of the problems and their associated real estate issues in geopolitical contexts. For the first time, this inductive research proposes a land-use typology that considers the complexity of the interrelationship between land policies, land-use theory, social theories of space and place and the exercise of extreme power over space. This paper produced a concept that is not easily measurable by quantitative nor qualitative approaches.

The land and town planning legislation concerning the planning of land use development within the united territorial communities (UTC) is considered. It is found that legislative norms need to be finalized. The necessity of updating the existing land management documentation developed prior to the adoption of the Law of Ukraine "On Land Management" and changes in the structure of urban development in connection with the adoption of the Law of Ukraine "On Regulation of Urban Development" was proved as they do not ensure the integrity of the planning process within the territories of these communities through their institutional incapacity (proved by the example of the Palan Unified Territorial Community of the Uman district of the Cherkasy region). The priority of land management and urban planning documents as the most influential tools in planning the development of land use systems in UTC is scientifically grounded and their interdependence established.

The accident at the Fukushima Daiichi Nuclear Power Plant has raised questions about the accumulation of radionuclides in soils, the transfer in the foodchain and the possibility of continued restricted future land use. This paper summarizes what is generally understood about the application of agricultural countermeasures as a land management option to reduce the radionuclides transfer in the food chain and to facilitate the return of potentially affected soils to agricultural practices in areas impacted by a nuclear accident.

<p>The assessment of climate change and land use modifications effects on hydrological cycle is challenging. We propose an approach based on Budyko theory to investigate the relative importance of natural and anthropogenic drivers on water resources availability. As an example of application, the proposed approach is implemented in the island of Sardinia (Italy), which is affected by important processes of both climate and land use modifications. In details, the proposed methodology assumes the Fu’s equation to describe the mechanisms of water partitioning at regional scale and uses the probability distributions of annual runoff (Q) in a closed form. The latter is parametrized by considering simple long-term climatic info (namely first orders statistics of annual rainfall and potential evapotranspiration) and land use properties of basins.</p><p>In order to investigate the possible near future water availability of Sardinia, several climate and land use scenarios have been considered, referring to 2006-2050 and 2051-2100 periods. Climate scenarios have been generated considering fourteen bias corrected outputs of climatic models from EUROCORDEX’s project (RCP 8.5), while three land use scenarios have been created following the last century tendencies.</p><p>Results show that the distribution of annual runoff in Sardinia could be significantly affected by both climate and land use change. The near future distribution of Q generally displayed a decrease in mean and variance compared to the baseline.   </p><p>The reduction of  Q is more critical moving from 2006-2050 to 2051-2100 period, according with climatic trends, namely due to the reduction of annual rainfall and the increase of potential evapotranspiration. The effect of LU change on Q distribution is weaker than the climatic one, but not negligible.</p>
