    Population and land use outmigrations from urban to peripheral areas can result in nonfunctional unmaintained historic structures which deteriorate to the point where removal is cheaper than removal or demolition by neglect The increasing rate of neglected historic structures is a growing concern There is a need for research investigating connections between urban growth management and its effect on neglect This paper applies Newmans 2013 conceptual model of measuring neglect to Geographic Information Systems comparing rates of neglect in historic Doylestown Quakertown and Bristol boroughs

    Globally, agricultural soils are being evaluated for their role in climate change regulation as a potential sink for atmospheric carbon dioxide (CO2) through sequestration of organic carbon as soil organic matter. Scientists and policy analysts increasingly seek to develop programs and policies which recognize the importance of mitigation of climate change and insurance of ecological sustainability when managing agricultural soils.

    Maize is a key global cash crop, produced in every continent except Antarctica. As a flex crop, it has multiple uses including for direct human consumption, as an ingredient for animal feed, as a key component in processed foods, or in ethanol production. According to figures from FAOSTAT, global production increased from 0.2 to 1.2 billion tons between 1961 and 2020.

    This research was conducted on an area of inland sands characterised by various degrees of overgrowth by vegetation and soil stabilisation. This landscape’s origin is not natural but is connected to human industrial activities dating from early medieval times, which created a powerful centre for mining and metallurgy. This study aims to identify the changes in the above- and belowground phytomass in the initial stages of succession and their influence on the chemical properties and morphology of the soil.

    Agriculture is an important type of land use but suffers from drought, especially under global climate change scenarios. Although government is a major actor in helping farmers to adapt to drought, lack of funds has constrained its efforts. Public-Private Partnership (PPP) mechanism has been widely applied in urban infrastructure development to raise fund for public goods and services, but very few studies explored its role in rural areas.

    Land degradation is a global issue receiving much attention currently. In order to objectively reveal the research situation of land degradation, bibliometrix and biblioshiny software packages have been used to conduct data mining and quantitative analysis on research papers in the fields of land degradation during 1990–2019 (data update time was 8 April 2019) in the Web of Science core collection database. The results show that: (1) during the past 20 years, the number of papers on land degradation has increased.
