The development of the forester's leadership role in forest land management is compared to rising profile of land between a sea or lake shoreline and a range of mountains, the progression is upward but the rate of climb changes. No plateau is identified. Reference is made to forestry leadership in several fields of forest land management; administration, land use, planning, research, forest management, recreational land use and fish and wildlife management. It is noted that forest land management includes activities for which foresters were not academically trained and reference is made to the fact that non-foresters, e.g. biologists and geographers are giving leadership in forest land management and thus providing beneficial competition and stimulation. The most important leadership role in the future may relate to regional planning. The forestry profession is cautioned not to abdicate this field to those in other disciplines.

This case study describes the application of a framework for developing stakeholder-driven scenarios of the future. The purpose of these scenarios is to inform land use planning toward the protection of ecosystems and derivable ecosystem services in Northwestern Virginia. We held two scenario development workshops with regional experts in conservation, agriculture, land use planning, policy, and economic development to create scenarios of land use in the northern Piedmont and northern Shenandoah Valley of Virginia. We structured the workshops around a framework that guided stakeholders through several steps eventually resulting in four unique scenarios describing the region in 50 years. Scenario narratives were defined by the intersection of highly influential and uncertain drivers of change relevant to land use planning and ecosystem services. Participants from the northern Shenandoah Valley region selected population growth and climate change adaptation as their scenario defining drivers, while participants from the northern Piedmont region selected planning strategy and climate change impact as their scenario defining drivers. Participants fleshed out scenarios into descriptive narratives that incorporated qualitative and quantitative measures of change. Details from the scenario narratives informed land use change models to further quantify tradeoffs between land use planning decisions and ecosystem services. Individuals interested in using scenario planning to guide research efforts, conservation, or land use planning, or even to broaden perspectives on how to view the future, will find value in this case study.

The land reclaimed from the seaside may have a long-term subsidence trend, which poses a potential geohazard in the future land use. Xiamen Xiang’an New Airport (XXNA) is built on reclaimed land since 2016. Based on the spaceborne Sentinel-1 data between January 2018 to April 2019 and the time series interferometric synthetic aperture radar (InSAR) technique, this paper analyzed the reclaimed land subsidence evolution at XXNA in this period. InSAR measurements show that XXNA is suffering from severe subsidence, mainly in three regions because of the earth and sand compacting. By analyzing the spatial subsidence characterizations of the main subsiding areas combined with historical land reclamation and future land use planning, we find the potential threat of subsidence to future land use. Correlation between subsidence and the period of reclamation was found, indicating that the consolidation and compression in dredger fill is the main cause of subsidence. By combining subsidence monitoring results with different land use types and adopting the Expectation (Ex) and Entropy (En) methods, we analyzed the key area with potential subsidence geo-hazard. This work shows that with SAR interferometry, it is possible to find the large area ground subsidence in the airport reclaimed area. The areas with potential subsidence geo-hazards are consistent with the deep reclaimed earth, which means high subsidence risk in the future.

This study aims to characterize the pollution conditions by measuring the concentrations of selected heavy metals. It also intends to investigate the relations between soil genesis and lithology. This provides knowledge about the future of the agricultural development in the area and helps decision makers in the land use planning.

Abstract. Increasing atmospheric carbon dioxide concentration [CO2] caused by anthropogenic activities has triggered a requirement to predict the future impact of [CO2] on forests. The Hindu Kush Himalayan (HKH) region comprises a vast territory including forests, grasslands, farmlands and wetland ecosystems. In this study, the impacts of climate change and land use change on forest carbon fluxes and vegetation productivity are assessed for HKH using the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS). LPJ-GUESS simulations were driven by an ensemble of three climate models participating in the CMIP5 (Coupled Model Intercomparison Project Phase 5) database. The modeled estimates of vegetation carbon (VegC) and terrestrial primary productivity were compared with observation-based estimates. Furthermore, we also explored the net biome productivity (NBP) and VegC over HKH for the period 1850–2100 under the future climate scenarios RCP2.6 and RCP8.5. A reduction is observed in modeled NBP and VegC from 1951–2005 primarily due to land use change. However, an increase in both NBP and VegC is predicted under RCP2.6 and RCP8.5. The findings of the study have important implications for management of the HKH region and inform strategic decision making, land use planning and clarify policy concerns.

Abstract. Increasing atmospheric carbon dioxide concentration [CO2] caused by anthropogenic activities has triggered a requirement to predict the future impact of [CO2] on forests. The Hindu Kush Himalayan (HKH) region comprises a vast territory including forests, grasslands, farmlands and wetland ecosystems. In this study, the impacts of climate change and land-use change on forest carbon fluxes and vegetation productivity are assessed for HKH using the Lund–Potsdam–Jena General Ecosystem Simulator (LPJ-GUESS). LPJ-GUESS simulations were driven by an ensemble of three climate models participating in the CMIP5 (Coupled Model Intercomparison Project phase 5) database. The modelled estimates of vegetation carbon (VegC) and terrestrial primary productivity were compared with observation-based estimates. Furthermore, we also explored the net biome productivity (NBP) and its components over HKH for the period 1851–2100 under the future climate scenarios RCP2.6 and RCP8.5. A reduced modelled NBP (reduced C sink) is observed from 1986–2015 primarily due to land-use change. However, an increase in NBP is predicted under RCP2.6 and RCP8.5. The findings of the study have important implications for the management of the HKH region, in addition to informing strategic decision making and land-use planning, and clarifying policy concerns.
