This article examines the evolving relations between Israel and the indigenous Bedouin Arab population of the southern Beer-Sheba region. It begins with a discussion of theoretical aspects, highlighting a structural conflict embedded in the ‘ethnocratic’ nature of nation-building typical of ‘pure’ settler states, such as Israel. The place of the Bedouin Arab community is then analyzed, focusing on the impact of one of Israel's central policies—the Judaization of territory. The study traces the various legal, planning and economic strategies of Judaizing contested lands in the study area. These have included the nationalization of Arab land, the pervasive establishment of Jewish settlements, the forced urbanization of the Bedouin Arabs, and the denial of basic services to Bedouins who refuse to urbanize. However, the analysis also finds a growing awareness among indigenous Arabs of their being discriminated against on ethnic grounds, and the emergence of effective resistance. In recent years, this has resulted in a deadlock between state authorities and the indigenous peoples. The case of the Bedouin Arabs demonstrates that the ethnocentric settler state is weakening and fragmenting, partially at least, due to its own expansionist land, planning and development policies.

The rapid economic growth, the exodus from rural to urban areas, and the associated extreme urban development that occurred in China in the decade of the 2000s have severely impacted the environment in Beijing, its vicinity, and beyond. This article presents an innovative approach for assessing mega-urban changes and their impact on the environment based on the use of decadal QuikSCAT (QSCAT) satellite data, acquired globally by the SeaWinds scatterometer over that period. The Dense Sampling Method (DSM) is applied to QSCAT data to obtain reliable annual infrastructure-based urban observations at a posting of ~1 km. The DSM-QSCAT data, along with different DSM-based change indices, were used to delineate the extent of the Beijing infrastructure-based urban area in each year between 2000 and 2009, and assess its development over time, enabling a physical quantification of its urbanization which reflects the implementation of various development policies during the same time period. Eventually, as a proxy for the impact of Beijing urbanization on the environment, the decadal trend of its infrastructure-based urbanization is compared with that of the corresponding tropospheric nitrogen dioxide (NO2) column densities as observed from the Global Ozone Monitoring Experiment (GOME) instrument aboard the second European Remote Sensing satellite (ERS-2) between 2000 and 2002, and from the SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY aboard of the ESA’s ENVIronmental SATellite (SCIAMACHY /ENVISAT) between 2003 and 2009. Results reveal a threefold increase of the yearly tropospheric NO2 column density within the Beijing infrastructure-based urban area extent in 2009, which had quadrupled since 2000.

The current research discusses opportunities and challenges of knowledge-based urban development in Egypt, aims to monitor the actual opportunities provided by Egyptian policies for knowledge-based urban development, and highlights their most important challenges. The research relied on the impact assessment methodology, the opinion of some experts, analyzing secondary data, literature review, and statistical reports to track the paths of changes in knowledge-based development policies and their applications during the third millennium to reveal the most important challenges and constraints facing the experiences of knowledge cities and its precincts in the Egyptian society. The research concluded some recommendations to confront these challenges and push forward toward strengthening knowledge-based urban development in Egypt, based on what came from critical review f literature, theoretical perspectives, and policies and experiences of many countries of the world in this field.

This chapter examines the impact of the National Economic Empowerment and Development Strategy (NEEDS), a socio-economic framework for enabling sustainable human development in Nigeria, and how it incorporates the basic targets of the Millennium Development Goals (MDGs) into government policy at both the national and grassroots levels. The chapter draws on the results of a study that was conducted to assess the specific impacts of the NEEDS policy in the process of improving the condition of existence in Nigeria by promoting socio-economic inclusivity. It considers the achievements of the NEEDS, the impediments that have constrained its functioning, and the lessons that have been or could be learnt from related achievements and failures of past development policies in Nigeria. It also offers some recommendations to make the NEEDS more effective in addressing the challenges and threats posed by poverty and other social incongruence in Nigeria.

The study attempts to examine the impact of social sector development on inclusive growth in India. Ever since Independence, India’s encounter with gnawing poverty and stark deprivation, particularly of the weaker and the marginalised sections of society, cajoled India’s planners to moot the development policies with the sole objective of exacerbating growth with equity. That is why since the beginning of the planning era, the stress had been laid on strengthening and expanding the social sectors with the premise that it would boost the inclusive growth agenda, manifesting in equal access to employment and economic opportunities; equal participation in decision-making and reduction in poverty and inequality. In conformity with the objective of our study, we intend to gauge the effect and contribution of different components of social sector development in India, on inclusiveness of growth using time series data for the period of 1985–1986 to 2015–2016. It was found that the expenditure related to ‘social security and welfare’ contributes significantly towards inclusive growth in India while the expenditure incurred on ‘welfare of marginalised class’ and ‘rural development’ exudes negative association with inclusiveness of growth.

Abstract. Hurricanes are infrequent but influential disruptors of ecosystem processes in the southeastern Atlantic and Gulf coasts. Every southeastern forested wetland has the potential to be struck by a tropical cyclone. We examined the impact of Hurricane Hugo on two paired coastal South Carolina watersheds in terms of streamflow and vegetation dynamics, both before and after the hurricane's passage in 1989. The study objectives were to quantify the magnitude and timing of changes including a reversal in relative streamflow difference between two paired watersheds, and to examine the selective impacts of a hurricane on the vegetative composition of the forest. We related these impacts to their potential contribution to change watershed hydrology through altered evapotranspiration processes. Using over 30 years of monthly rainfall and streamflow data we showed that there was a significant transformation in the hydrologic character of the two watersheds – a transformation that occurred soon after the hurricane's passage. We linked the change in the rainfall–runoff relationship to a catastrophic change in forest vegetation due to selective hurricane damage. While both watersheds were located in the path of the hurricane, extant forest structure varied between the two watersheds as a function of experimental forest management techniques on the treatment watershed. We showed that the primary damage was to older pines, and to some extent larger hardwood trees. We believe that lowered vegetative water use impacted both watersheds with increased outflows on both watersheds due to loss of trees following hurricane impact. However, one watershed was able to recover to pre hurricane levels of evapotranspiration at a quicker rate due to the greater abundance of pine seedlings and saplings in that watershed.

This paper aims at exploring the impact of urbanization and financial development on electricity intensity in China during the period 2004-2018. By employing a panel vector autoregressive (VAR) approach, the study finds that the electricity intensity response to one standard deviation shock on urbanization shows a negative impact, and a positive shock to financial development initially increases electricity intensity and eventually decreases electricity intensity. Our analysis is important for policy makers for improving electricity efficiency planning and sustainable economic development policies.
