The cultivation of bioenergy crops could be considered as sustainable; however, its use in fertile lands could conflict with food production. The general purpose of this study is to identify areas where traditional food crops are not economically sustainable, but where they could be substituted by energy crops without changing the land use in Spain. We studied the profit margin of the main crops of the country, which are wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.), the spatial location of the growing areas, and the biophysical constraints.

Urbanization brings significant changes to the urban food system. There is growing attention to food self-sufficiency in metropolitan areas for the concern of greenhouse gas (GHG) mitigation in food transportation. In China, grain self-sufficiency in metropolitan areas is also an important issue for grain security and involves coordination among contradictory policy goals. Based upon a comprehensive statistical analysis of 70 metropolitan areas in mainland China, we investigated the regional differences in the trends of grain self-sufficiency capacity in these areas from 1990 to 2015.

Economic efficiency is the key issue of sustainable development in urban agglomerations. To date, more attention has been paid to the estimates of productivity gains from urban agglomerations. Differing from the previous studies, this paper focuses on the influencing factors and mechanisms of the economic efficiency of urban agglomerations, and check the effects of three different externalities (industrial specialization, industrial diversity and industrial competition) on the economic efficiency of urban agglomerations.

In this article, the authors propose an impact assessment method for life cycle assessment (LCA) that adheres to established LCA principles for land use-related impact assessment, bridges current research gaps and addresses the requirements of different stakeholders for a methodological framework. The conservation of biodiversity is a priority for humanity, as expressed in the framework of the Sustainable Development Goals (SDGs). Addressing biodiversity across value chains is a key challenge for enabling sustainable production pathways.

Soil nutrients are of great significance for maintaining forest growth and ensuring land productivity. A comprehensive scientific evaluation of soil fertility is helpful for sustainable forest management. There are many uncertainties in traditional evaluation methods, that is fuzziness and randomness, which often lead to a large deviation of the evaluation results. In order to comprehensively consider the fuzziness and randomness of soil fertility evaluation, the cloud model was introduced to evaluate the soil fertility of Chinese fir plantations.

Residential carbon dioxide emissions can be divided into a direct component caused by consumers via direct energy usage and an indirect component caused by consumers buying and using products to meet their needs, with a higher proportion caused by the latter. Based on Beijing panel data for 1993–2012, an economic boom period in China, indirect carbon dioxide emissions were separately calculated for urban and rural households using the consumer lifestyle approach (CLA) model.

Designing and implementing investment projects are activities that have a direct impact on the natural environment and pose a threat to sustainable development of rural areas. The issue of agricultural production space protection during the implementation of linear projects in Poland is often only mentioned at the design stage as the final element. The aim of the study is to propose a tool to enable an assessment and modelling of a motorway design variant in order to minimise the impact on the agricultural production space.

Expansion of arid lands due to climate change, particularly in water stressed regions of the world can have severe implications on the economy and people’s livelihoods. The spatiotemporal trends in aridity, the shift of land from lower to higher arid classes and the effect of this shift on different land uses in Syria have been evaluated in this study for the period 1951–2010 using high-resolution monthly climate data of the Terrestrial Hydrology Research Group of Princeton University.

Mallorca keeps an age-old biocultural heritage embodied in their appealing landscapes, largely exploited as an intangible tourist asset. Although hotel and real estate investors ignore or despise the peasant families who still persevere in farming amidst this worldwide-known tourist hotspot, the Balearic Autonomous Government has recently started a pay-for-ecosystem-services scheme based on the tourist eco-tax collection that offers grants to farmers that keep the Majorcan cultural landscapes alive, while a growing number of them have turned organic.

Slovakia faces a critical period in land and property management. The Land Registry still maintains its old 1990s information system and obsolete manual record system, whose structure and links of the real estate records and ownership titles are unable to meet the current requirements of companies in its graphical representation and visualization of data. Basically, it is a partially structured, digitalized and yet still analog system for recording land titles.

One of the contemporary citys ambition nowadays is to be more comfortable flexible and coeval Although numerous urban design attempts have appeared to enhance the users gratification there are urgent demands to upgrade the classical public space to be more agreeable with the necessities of everyday life Most of the urban areas after industry era are zoning based meanwhile have been less adaptable to daily life conditions economically environmentally and psychologically alike The zoning based space has a single activity such as public or private workspace or leisure space etc while the urgen

The paper seeks to assess the impact of access to the land of Egypt on urban development in an attempt to identify policies and laws that can be categorized as a catalyst in urban conflict A systematicreview of Data on land tenure environment of Egypt land access land governance and tenure security the actors involved in these processes their roles the land tenure related challenges they face and measures that can be taken to address these challenges was collected at country level In the context of Egypt Access to land is deemed with obstacles confronting beneficiaries and legal procedures
