Illegal changes of use in aged industrial and residential buildings is now a prevalent problem in Hong Kong. This research aims to develop a strategy for an effective and efficient control of illegal land use in a highly dense environment, with high rise buildings in multiple leasehold ownerships.

Multiple cases were qualitatively analyzed, based on documentary analysis of the court proceedings.

In Cases 1 and 2, lease conditions for restriction to industrial purposes on aged industrial buildings were found to be obsolete and not economically viable, thus resulting in illegal conversion of the premises for commercial use. Cases 2 and 3 showed that ambiguity in user clauses in land leases could lead to illegal changes of use from industrial or residential to commercial activities. Most importantly, Cases 1 and 3 demonstrated that limited resources for lease enforcement are the fundamental cause of the problem. Cases 4 and 5 proved that property managers could take effective legal action against changes of use in buildings with multiple ownerships.

The results of this study are derived from five typical cases in Hong Kong, but they form a baseline upon which further research can build to test their significance in many other settings. Ultimately, a more robust strategy can be developed for ensuring an effective and efficient control of illegal land uses in the leasehold system for Hong Kong and for those countries with a similar tenure system.

A total economic and management strategy should be implemented by the government. The land management system should work in partnership with private property managers which are empowered under the Deed of Mutual Covenant (DMC) of multiple occupied buildings to take instant action against individual owners for breaches of lease conditions. The system should also be more flexible to expand the scope of new uses for aged industrial premises, allow affordable premium for lease modifications, as well as review and clarify any ambiguous user clauses in the related land ordinances.

The public should be educated that it is important to seek approvals and consents from the government prior to making any changes of land use. The government should also establish a housing policy to provide sufficient affordable housing for the lower income group so that illegal sub‐divisions on buildings for residential purposes can be eliminated.

The improvement measures identified can effectively enforce compliance with lease conditions, which in turn can reduce the enforcement transaction costs, ensure efficient allocation and use of land in the leasehold system, and maintain building safety.

Bioenergy is a key component of climate change mitigation strategies aiming at low stabilization. Its versatility and capacity to generate negative emissions when combined with carbon capture and storage add degrees of freedom to the timing of emission reductions. This paper aims to explore the robustness of a bioenergy-based mitigation strategy by addressing several dimensions of uncertainty on biomass potential, bioenergy use and induced land use change emissions.

Different mitigation scenarios were explored by two different energy-economy optimization models coupled to the same land use model, which provides a common basis for the second generation bioenergy dynamics in the two energy-economy models.

Using bioenergy is found to be a robust mitigation strategy as demonstrated by high biomass shares in primary energy demand in both models and in all mitigation scenarios.

A variety of possible storylines about future uses of biomass exist. The comparison of the technology choices preferred by the applied models helps understand how future emission reductions can be achieved under alternative storylines.

The presented comparison-based assessment goes beyond other comparison studies because both energy-economy models are coupled to the same land use model.

Drawing from recent research on the West African country the Gambia, the proposed chapter illustrates the interactions between climate change and land use and management in a developing country and, in addition, explores the drivers of national climate change impacts on agriculture and other land uses.

The objective of this chapter is to provide an approach to the farmland abandonment problem in Galicia, the Spain’s north-western region. We describe the land use pattern that characterized the traditional agricultural system, and analyze the process of structural adjustment and changes in land use recorded in the last 50 years. The empirical basis is provided mainly by an original elaboration of agricultural census data for the period 1982–2009. The results show that in the last five decades the area devoted to crops and pastures was constrained to a small portion of the territory (just over 20%), while the agro-livestock uses of hill land which were very important up to the mid-twentieth century disappeared. All this led to a remarkable expansion of abandoned land, which currently occupies at least 20% of the regional area. The drivers of this farmland abandonment are diverse and vary from one zone to another. But among them the conditioners derived from the structure of land ownership must be emphasized, coupled with the poor functioning of the land market and leasing. Land abandonment has had a major impact on the dynamics of the agricultural sector, limiting the size of farms and causing an increasing intensification in a small portion of the territory. This has also led to severe environmental problems, especially forest fires. Consequently, improving mobility and land use should be a priority of agricultural and rural development policies in this region.

The present study assesses the morphological transition and the consequent changes in the use of land observed recently in southern Europe. We analysed the spatial distribution of basic land-use classes (built-up areas, cropland, forests) together with demographic and socioeconomic indicators with the aim to evaluate the differential impact of compact urban expansion and dispersed urbanization on peri-urban farming. Alternating distinct expansion waves over the last 50 years, Athens’ metropolitan region, Greece, was selected as the case study. Although per-capita built-up area was higher in the ‘dispersed’ urban wave compared with the ‘compact’ wave, cropland was the most vulnerable class to urbanization. A high rate of conversion from forests to cropland (in turn abandoned and, finally, developed) was observed since the early 1990s. This process is associated to land fragmentation and soil degradation driven by illegal housing and real estate speculation. Land-use changes are a target for policies mitigating soil consumption and promoting peri-urban agriculture on Mediterranean fringe land.

This paper seeks to discuss how an environmental change for an organisation can be a catalyst for the take‐up of intellectual capital (IC). In particular, it uses Laughlin's “colonizing” model of organisational change to understand the catalyst for change, being an ageing workforce, and the resultant formation of an accounting of IC.

This paper presents a case study of an Australian public sector organisation, which has created and implemented IC practice.

In this case, the impending retirements of the “baby boomer” generation were an environmental disturbance and a catalyst that allowed for an accounting of IC, especially its human capital.

This case study is limited to the presentation of findings of a phenomenon within a particular organisation within the Australian public sector context. Other forces may also have had an effect on the organisation, if not for the presence of the “ageing workforce” disturbance.

The paper contributes to the literature on IC by examining the impact of the take‐up of IC from inside a public sector organisation perspective.

Between 2006 and 2016, local communities in semi-arid Bobirwa sub-district in the Limpopo Basin part of Botswana had endured notable fluctuations in the delivery of critical ecosystem services. These changes have been coupled with adverse effects on local people’s livelihood options and well-being. However, a few such studies have focussed on the semi-arid to arid landscapes. This study therefore aims to provide recent knowledge and evidence of consequences of environmental change on semi-arid arid landscapes and communities.

To examine these recent changes in key ecosystem services, the authors conducted six participatory mapping processes, eight key informant interviews and several rapid scoping appraisals in three study villages. The analyses were centred on changes in seasonal quantities, seasonality, condition of ecosystem service sites, distance to ecosystem service sites and total area providing these services. Drivers of change in the delivery of key ecosystem services and the associated adverse impacts on human well-being of these recent changes in bundles of ecosystem services delivered were also analyzed.

Results show that adverse weather conditions, drought frequency, changes in land-use and/or land-cover together with unsustainable harvesting because of human influx on local resources have intensified in the past decade. There was circumstantial evidence that these drivers have resulted in adverse changes in quantities and seasonality of key ecosystem services such as edible Mopane caterpillars, natural pastures, wild fruits and cultivated crops. Similarly, distance to, condition and total area of sites providing some of the key ecosystem services such as firewood and natural pastures changed adversely. These adverse changes in the key ecosystem services were shown to increasingly threaten local livelihoods and human well-being.

This paper discusses the importance of engaging rural communities in semi-arid areas in a participatory manner and how such information can provide baseline information for further research. The paper also shows the utility of such processes and information toward integrating community values and knowledge into decisions regarding the management and utilization of local ecosystem services under a changing climate in data-poor regions such as the Bobirwa sub-district of Botswana. However, the extent to which this is possible depends on the decision makers’ willingness to support local initiatives through existing government structures and programmes.

This study shows the importance of engaging communities in a participatory manner to understand changes in local ecosystem services considering their unique connection with the natural environment. This is a critical step for decision makers toward integrating community values in the management and utilization of ecosystem services under a changing climate as well as informing more sustainable adaptive responses in semi-arid areas. However, the extent to which decision makers can integrate such findings to inform more sustainable responses to declining capacity of local ecosystems in semi-arid areas depends on how they value the bottom-up approach of gaining local knowledge as well as their willingness to support local initiatives through existing government structures and programmes.

The purpose of this paper evaluates the effects of the Great Western Development (GWD) policy on agricultural intensification, land use, agricultural production and rural poverty in western China.

The authors collect county-level data on land use, input application, grain crop production, income, poverty and geophysical characteristics for 1996–2005 and use a quasi-natural experimental design of difference-in-differences (DD) in the empirical analysis.

Results suggest that the GWD policy significantly increased the grain crop production in western China. This increase resulted from higher yield, with increased fertilizer use and agricultural electricity consumption per hectare, and more land allocated to grow grain crops. The policy also increased land-use concentration, reduced crop diversity and alleviated rural poverty in western China.

This paper makes three contributions. First, the authors add to the growing literature on the GWD policy by evaluating its effects on farm household decisions and exploring the mechanisms and broad socioeconomic impacts in western China. Second, the authors take advantage of a quasi-natural experimental design to improve the identification strategy where input use, land allocation, production and off-farm labor participation are all endogenous in a farm household. Third, the authors explore a long list of variables within one integrated dataset to present a comprehensive picture of the impact of the GWD policy.

Housing is a composite asset comprising land and improved components varying as proportions of total value over space and time. Theory suggests land and improvements (structures) are unique goods responding differently to economic stimuli. This paper aims to test the expectation of different overall house price changes in response to variation in land and improved components.

House price dynamics are decomposed to analyse the influence of land and structure components for the city of Perth, Australia both at aggregate level and for spatially defined housing sub-regions, sample period 1995-2010.

Values of land and improvements on that land evolve differently over time and are significantly influenced by the magnitude of land leverage. The study extends previous research through extensive spatial disaggregation of a larger more detailed data set than previously used in studies of this type confirming significant variation in land leverage ratios, overall price change and growth rates for land and improvements in sub-regional markets defined by spatial criteria.

The results suggest an important role for policy development with respect to housing affordability and supply side regulation of land in large urban housing markets.

The results suggest important implications for hedonic price analysis of housing markets. The inclusion of land leverage variables in hedonic regression could remove coefficient bias associated with omitted location amenity variables.

The paper adapts methodology from previous studies but extends previous literature through detailed analysis of a large Australian housing market (Perth) enabling extensive spatial disaggregation of the sample and providing greater insight to spatial variation of land leverage than in previous studies.

Consistent and reliable data on farmland values is critical to assessing the overall financial health of agricultural producers. However, little is known about the idiosyncrasies and similarities of standard land value data sources – US Department of Agriculture (USDA), Federal Reserve Bank land value surveys, and transaction prices. The purpose of this paper is to determine the differences and similarities of land value movements from three land value data sources.

In addition to Oklahoma transaction prices, two survey sources are considered: the USDA annual report and the quarterly Tenth District Survey of Agricultural Credit Conditions administered by the Federal Reserve Bank of Kansas City. The paper describes each data set and identifies differences in data sampling, collection, and reporting. Average values of Oklahoma farmland across data sources are examined. USDA estimates are regressed against quarterly Federal Reserve values across multiple states to determine the point in time represented by USDA estimates. Granger causality tests determine if Federal Reserve land value estimates anticipate movements in USDA land value estimates.

It is found that all three data sources are highly correlated, but transaction prices tend to be higher, especially for irrigated cropland and ranchland. USDA land values are reported as representing land values on January first, but instead they more closely represent first and second quarter land values according to a multi‐state comparison to changes in quarterly Federal Reserve land values. Given the finding that first quarter Federal Reserve Bank land values lead USDA land values and that they are published before the USDA release, Federal Reserve land values are a timely indicator of agricultural producers' financial position.

No previous research has addressed the topic of how various sources of agricultural land values compare.
