Urbanization has been contributing more in global climate warming, with more than 50% of the population living in cities. Rapid population growth and change in land use / land cover (LULC) are closely linked. The transformation of LULC due to rapid urban expansion significantly affects the functions of biodiversity and ecosystems, as well as local and regional climates. Improper planning and uncontrolled management of LULC changes profoundly contribute to the rise of urban land surface temperature (LST). This study evaluates the impact of LULC changes on LST for 1997, 2007 and 2017 in the Rajshahi district (Bangladesh) using multi-temporal and multi-spectral Landsat 8 OLI and Landsat 5 TM satellite data sets. The analysis of LULC changes exposed a remarkable increase in the built-up areas and a significant decrease in the vegetation and agricultural land. The built-up area was increased almost double in last 20 years in the study area. The distribution of changes in LST shows that built-up areas recorded the highest temperature followed by bare land, vegetation and agricultural land and water bodies. The LULC-LST profiles also revealed the highest temperature in built-up areas and the lowest temperature in water bodies. In the last 20 years, LST was increased about 13ºC. The study demonstrates decrease in vegetation cover and increase in non-evaporating surfaces with significantly increases the surface temperature in the study area. Remote-sensing techniques were found one of the suitable techniques for rapid analysis of urban expansions and to identify the impact of urbanization on LST.

Urban expansion is a dynamic and complex phenomenon, often involving adverse changes in land use and land cover (LULC). This paper uses satellite imagery from Landsat-5 TM, Landsat-8 OLI, Sentinel-2 MSI, and GIS technology to analyse LULC changes in 2000, 2005, 2010, 2015, and 2020. The research was carried out in Opole, the capital of the Opole Agglomeration (south-western Poland). Maps produced from supervised spectral classification of remote sensing data revealed that in 20 years, built-up areas have increased about 40%, mainly at the expense of agricultural land. Detection of changes in the spatial pattern of LULC showed that the highest average rate of increase in built-up areas occurred in the zone 3–6 km (11.7%) and above 6 km (10.4%) from the centre of Opole. The analysis of the increase of built-up land in relation to the decreasing population (SDG 11.3.1) has confirmed the ongoing process of demographic suburbanisation. The paper shows that satellite imagery and GIS can be a valuable tool for local authorities and planners to monitor the scale of urbanisation processes for the purpose of adapting space management procedures to the changing environment.

Foreign land grabbing is acknowledged as a phenomenon that generates disempowerment and dispossession of local farmers, human rights violations. Previous studies have revealed the lack of ethical benchmarks in foreign large-scale land transactions that raise moral concerns. It is evident that when resources are scarce and people depend on them, the balance between values and interests transforms itself into a dilemma. Within this context, the aims of the paper were to bring to the fore critical reflection on a more ethical perspective of large-scale land acquisitions and to extend the scant information on what factors determine landowners not to sell their land to foreigners to limit land grabbing. This context justifies the need for a critical reflection on a more ethical perspective of large-scale land acquisitions. Therefore, two objectives were set. The first one is to document the role of ethics in large-scale land transactions. Based on the land grabbing literature, authors selected a set of eight land grabbing narratives, most often interrelated and overlapping, that pose ethical considerations. The second objective is to reveal how well a set of variables can predict the “Resistance to sell” the land to foreigners even when an attractive price is offered. As ethics is a social construct, the analysis captured the stakeholders’ perspective on land grabbing. Therefore, a questionnaire was applied to a sample of 332 Romanian landowners from twelve randomly selected counties to reveal their perceptions. Partial least squares structural equation modeling (PLS-SEM) was used to observe how well a set of seven variables could predict landowners’ “Resistance to sell” their land to foreign buyers. The use of PLS-SEM was justified by the existence of single items and the need to examine many structural model relations. Results showed that the variables with the strongest contribution to the prediction of the dependent variable are the “Probability to join an association for farmers rights defense”, the “Importance of the land price offered by the potential foreign buyer”, and the “Perceived effect of agricultural land conversion to urban land”. Raising awareness on the importance of buyer attributes, increasing people’s perception of the negative effect of agricultural land conversion to urban land, or strengthening the state’s image as a necessary actor to limit land grabbing will increase landowners’ resistance to sell their land to foreigners. Finally, it can be inferred that, within this frame of discussion, ethics should be valued as a means to create economically viable and morally justifiable solutions for foreign large-scale land transactions.

AbstractIn a country like Ethiopia where the vast majority of the populations are employed in agriculture, land is an important economic resource for the development of rural livelihoods. Agricultural land in peri-urban areas is, however, transformed into built-up regions through horizontal urban expansion that has an effect on land use value. In recent years Ethiopia has been experiencing rapid urbanization, which has led to an ever-increasing demand for land in peri-urban areas for housing and other nonagricultural activities that pervades agricultural land. There is a high demand for informal and illegal peri-urban land which has been held by peri-urban farmers, and this plays a vital role in the unauthorized and sub-standard house construction on agricultural land. This urbanization has not been extensively reviewed and documented. In this review an attempt has been made to assess the impacts of rapid urbanization on agricultural activities. Urban expansion has reduced the areas available for agriculture, which has seriously impacted upon peri-urban farmers that are often left with little or no land to cultivate and which has increased their vulnerability. Housing encroachments have been observed to be uncontrolled due to a weak government response to the trend of unplanned city expansion. This has left peri-urban farmers exposed to the negative shocks of urbanization because significant urbanization-related agricultural land loss has a positive correlation with grain production decrease. Appropriate governing bodies should control urban development in order to control the illegal and informal spread of urbanization on agricultural land that threatens food production.

Land is one of the most valuable assets required for agricultural production. In Africa, smallholder agricultural producers are faced with a lot of challenges that have highly impacted on productivity and sustainable food systems. The global demand for agricultural land for food and bio-fuel production has increasingly led to the emergence of land grabbing after the 2007-08 food price crisis. The rural poor are the victim of land grabbing as they are faced with declining farmlands, low income generation, and loss of livelihood activities. These have affected the food security status of the rural poor as farmlands are taken from them. The proponents of land grabbing revealed that developing countries are expected to benefit from investments inflow on grabbed land, development of infrastructure, increased income generation, and job creation. They argue that investment in agriculture is necessary to stimulate agricultural production; however, this situation has brought negative effects as most investors failed to keep their end of the transaction on land acquisition deals.

Cities in developing countries are urbanising at a rapid rate, resulting in substantial pressures on environmental systems. Among the main factors that lead to flooding, controlling land-use change offers the greatest scope for the management of risk. However, traditional analysis of a “from–to” change matrix is not adequate to provide information of all the land-use changes that occur in a watershed. In this study, an in-depth analysis of land-use change enabled us to quantify the bulk of the changes accumulating from swap changes in a tropical watershed. This study assessed the historical and future land-use/land-cover (LULC) dynamics in the River State region of the Niger Delta. Land-use classification and change detection analysis was conducted using multi-source (Landsat TM, ETM, polygon map, and hard copy) data of the study area for 1986, 1995, and 2003, and projected conditions in 2060. The key findings indicate that historical urbanisation was rapid; urban expansion could increase by 80% in 2060 due to planned urban development; and 95% of the conversions to urban land occurred chiefly at the expense of agricultural land. Urban land was dominated by net changes rather than swap changes, which in the future could amplify flood risk and have other severe implications for the watershed.

Indian agricultural companies have been involved in the recent trend in large-scale overseas acquisitions of farmland, criticized as “land grabbing”. India has joined China, Kuwait, Saudi Arabia and South Korea among other nations heavily investing in large-scale agricultural projects in Africa and elsewhere. Several factors are driving India's effort to “outsource its food production,” including the Government's growing strategic concerns about ensuring long-term food security and concerns about falling ground water tables. Eager developing country governments have also courted Indian agricultural investors, offering special incentives, including offers to lease massive tracts of arable land on very generous terms at much cheaper rates than land and water in India. The Indian Government has supported this trend through high-level trade diplomacy, foreign aid, and subsidized credit for its agricultural companies investing overseas. Critics call the trend “land grabbing” and claim there have been negative impacts on local peoples, who are often displaced in the process. The public disclosure of lease contracts between the Ethiopian Government and five Indian investors sheds light on the negative ethical, political, human rights and environmental consequences for local people in host countries. New and ongoing advocacy strategies are discussed, including the idea to establish international advocacy linkages between Indian activists fighting for small farmers rights and addressing “land grabbing” actions within India, and small farmers in Africa and elsewhere facing similar problems. One idea is for such linkages to inform Indian citizens who can take action to address the problem of land-grabbing by Indian companies operating overseas. International land rights advocates see a common struggle in which land deals must involve transparent and participatory relations between governments, companies and local democratic communities.

Abstract The Mediterranean landscape has been rapidly changing over the past decades. Many regions saw a population decline, which resulted in changing land use, abandonment of marginal lands and colonisation by shrubs and tree species. Typical features like farming terraces, olive yards, and upland grasslands have been decreasing over the past 50 years. This results in a declining biodiversity and loss of traditional Mediterranean landscapes. In this paper we assess the landscape changes that took place in two areas, in Portofino, on the Italian Riviera, and Lesvos, a Greek island near the Turkish coast. We compared land use maps and aerial photographs over the past decades to quantify the land use changes in these two areas. Additional information was acquired from farmers’ interviews and literature. We found that changes are related to societal changes in the appraisal of agricultural land uses, and to the urban expansion, tourism and recreation. These diffuse processes are a result of policy measures and autonomous societal transformations. This is confirmed by the results of two interview surveys: between 1999 and 2012 agricultural land use in Portofino regional Park and buffer zone further marginalised, and the associated landscape changes are perceived as a substantial loss of character and identity. This problem is emblematic for large parts of the Mediterranean. Comparing different landscapes reveal similar processes of landscape change, which can be related to similar driving forces. Based on such comparisons, we learn about possible trajectories of change, and ask for a comprehensive approach to land use management.
