Global Population

A key challenge for humanity is how a future global population of 9 billion can all be fed healthily and sustainably. Here, we review how competition for land is influenced by other drivers and pressures, examine land-use change over the past 20 years and consider future changes over the next 40 years. Competition for land, in itself, is not a driver affecting food and farming in the future, but is an emergent property of other drivers and pressures. Modelling studies suggest that future policy decisions in the agriculture, forestry, energy and conservation sectors could have profound effects, with different demands for land to supply multiple ecosystem services usually intensifying competition for land in the future. In addition to policies addressing agriculture and food production, further policies addressing the primary drivers of competition for land (population growth, dietary preference, protected areas, forest policy) could have significant impacts in reducing competition for land. Technologies for increasing per-area productivity of agricultural land will also be necessary. Key uncertainties in our projections of competition for land in the future relate predominantly to uncertainties in the drivers and pressures within the scenarios, in the models and data used in the projections and in the policy interventions assumed to affect the drivers and pressures in the future.

Economic Ties

China has significantly enhanced its position and interest in the Persian Gulf region over the past 25 years, making it an important newcomer in regional dynamics. Evidence clearly shows that it has expanded, in some cases dramatically, its diplomatic contacts, economic ties, and arms sales to regional states. This represents a novel development which is likely to accelerate in the future as China's dependence on Persian Gulf oil grows. China's rising position in the region has put Beijing and Washington at odds and could generate serious friction points in the future. Policy recommendations are sketched to avoid such an outcome.

"Based on recent research, we aim to present the current global religious configu-ration, the religious demographic evolution during the twentieth century, and the main trends for the first half of the twenty-first century. From a methodological point of view, we chose to present only those religions that register a share of 1% of the global population, among which we paid increased attention only to Christiani-ty and Islam. The only exception to this rule is Judaism, the reason for advancing this exception being the desire to compare the evolution of the three religions of the Book: Judaism, Christianity, and Islam. The purpose of this presentation is to provide a more nuanced picture of the geographical distribution of each religion and, on the other hand, to illustrate the global religious diversity. From a chronological point of view, the landmarks are the years 1910, 1970, 2000, 2010, 2014, 2030, and 2050. The data collected for the years 1910–2014 is the basis of the forecasts for the years 2030 and 2050. The former ones describe the religious realities, while the latter two open up perspectives on the trends in religious demography. We would like to draw attention to the potential of religious demography in deciphering the religious image of the world in which we live. On the other hand, we consider that exploring the global religious profile and the way it evolves, as well as the factors that bring forth change, is not only an opportunity generated by the organic development of religious demography research but also a necessity for rethinking the pastoral and missionary strategies of the church. Religious demographics provide valuable data about the past together with nuanced knowledge of the present, helping us anticipate and even influence the future. The church, at any time, assumes the past, manages the present, and prepares the future. From this perspective, we believe that a strategic pastoral thinking, regardless of religion or denomination, can be organically outlined, starting from the data provided through the means available to religious demography. While religious demography provides specific data, it does not explain the phenomena behind this data; it notes and invites questions, debates, and explanations about religious affiliation, religiosity, and religious behaviour.

The Impact

ABSTRACTThe combination of population ageing and climate change is creating a new threat for many Australian coastal hamlets vulnerable to the impact of tropical cyclones. Increasingly, elderly people are facing future tropical cyclones alone, without support from family and friends, relying instead on already stretched government and authority resources, despite Emergency Management Australia's (EMA) policy expectation that all citizens must be self-reliant. This research explored the future self-reliance and disaster resilience of coastal hamlets through the lens of the Social Cognitive Theory by outlining the findings from focus groups, personal interviews and questionnaires involving participants over 65 years of age, residing in townships previously impacted by Cyclone Larry (in 2006) and Cyclone Yasi (in 2011). Participants recalled a lack of social support following the cyclones, a fear of evacuating their homes, as well as the trauma of recovering from such intense destruction. Respondents were also concerned about the physical, cognitive and financial impacts of ageing on their ability to prepare and recover from future cyclones, frightened that experiences from the past might be repeated in the future, contributing to feelings of isolation, frustration and the loss of community, and a rethinking of ageing in the place of their choice. These considerations impact on the dependence EMA has that all citizens will remain self-reliant when faced with a natural hazard and should be considered when making future policy decisions in relation to more isolated coastal townships.

Change of land use land cover (LULC) has been known globally as an essential driver of environmental change. Assessment of LULC change is the most precise method to comprehend the past land use, types of changes to be estimated, the forces and developments behind the changes. The aim of the study was to assess the temporal and spatial LULC dynamics of the past and to predict the future using Landsat images and LCM (Land Change Modeler) by considering the drivers of LULC dynamics. The research was conducted in Nashe watershed (Ethiopia) which is the main tributary of the Upper Blue Nile basin. The total watershed area is 94,578 ha. The Landsat imagery from 2019, 2005, and 1990 was used for evaluating and predicting the spatiotemporal distributions of LULC changes. The future LULC image prediction has been generated depending on the historical trends of LULC changes for the years 2035 and 2050. LCM integrated in TerrSet Geospatial Monitoring and Modeling System assimilated with MLP and CA-Markov chain have been used for monitoring, assessment of change, and future projections. Markov chain was used to generate transition probability matrices between LULC classes and cellular automata were used to predict the LULC map. Validation of the predicted LULC map of 2019 was conducted successfully with the actual LULC map. The validation accuracy was determined using the Kappa statistics and agreement/disagreement marks. The results of the historical LULC depicted that forest land, grass land, and range land are the most affected types of land use. The agricultural land in 1990 was 41,587.21 ha which increased to 57,868.95 ha in 2019 with an average growth rate of 39.15%. The forest land, range land, and grass land declined annually with rates of 48.38%, 19.58%, and 26.23%, respectively. The predicted LULC map shows that the forest cover will further degrade from 16.94% in 2019 to 8.07% in 2050, while agricultural land would be expanded to 69,021.20 ha and 69,264.44 ha in 2035 and 2050 from 57,868.95 ha in 2019. The findings of this investigation indicate an expected rapid change in LULC for the coming years. Converting the forest area, range land, and grass land into other land uses, especially to agricultural land, is the main LULC change in the future. Measures should be implemented to achieve rational use of agricultural land and the forest conversion needs to be well managed.
