    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.

    Suzhou city was the cultural centre of ancient south China. It continues the urban pattern of more than 800 years ago. Suzhou gardens are the essence of Chinese gardening art, as well as the valuable world cultural heritage site. This paper compared the evolution in the distribution and scale of Suzhou gardens among five historical periods, and discussed the influence of urbanization on gardening.

    China, a country developing at unprecedented levels, has experienced drastic changes throughout its recent economic history. Of primary interest is the continuing development and improvement of the rural agricultural sector, with even the slightest changes in this sector having dramatic ripple effects on rural economies. Estimates of rural households involved in agricultural production range from 65 to 70 percent (de Brauw & Rozelle, 2008; Rozelle, Taylor, & de Brauw, 1999).

    This study assesses the determinants of forest land allocation to households in the forest tenure reforms in China in the period 1980-2005 using data from three provinces in Southern China; Fujian, Jiang Xi and Yunnan. Furthermore, it assesses the current level of tenure security on forest land and how this tenure security is affected by past and more recent policy changes.

    Desertification, land degradation and drought affect more than 2 billion people and the situation might worsen due to the unsustainable use of soil and water under present scenarios of climate change. The UNCCD 10-year strategy points out the importance of science, knowledge sharing systems and awareness raising to support policymakers in reversing this trend. Sustainable land management practices, including sustainable agriculture, provide important local, regional and global benefits.

    Asia and the Pacific, for the purposes of this book, encompasses a vast territory extending from Mongolia in the north to New Zealand in the south; from the Cook Islands in the east to Kuwait in the west (Map 1). The environmental diversity of Asia and the Pacific is therefore vast, and is contrasted by the region’s coldest and hottest deserts, verdant tropical rainforests, extensive steppe, desert steppe, grassland and rangelands, mountains and plains.

    A number of severe ecological problems, and the altered structure of urban spaces, are ascribed to rapid urbanisation. Hence, an analytical framework for urban spatial structure and functional optimisation is highly beneficial to balance the contradiction between developing urban areas and protecting their ecosystems. In this paper, the proposed analytical framework included three parts. We first delineated the ecological suitability zones (ESZs) of Beijing City by applying the minimum cumulative resistance (MCR) model.

    Though forest ecosystems play a critical role in enhancing ecological, environmental, economic, and societal sustainability, on a global scale, their future outlooks are uncertain given the wide-ranging threats they are exposed to. The uniqueness of this study is to provide a line of evidence in which forest change trajectories are not only tracked but also evaluated through the lenses of forestry and economic oriented events’ timelines. The dynamics of forest change trajectories were mined using a temporal model.

    Although the way in which vegetation phenology mediates the feedback of vegetation to climate systems is now well understood, the magnitude of these changes is still unknown. A thorough understanding of how the recent shift in phenology may impact on, for example, land surface temperature (LST) is important. To address this knowledge gap, it is important to quantify these impacts and identify patterns from the global to the regional scale.

    Based on the background of the change in the urban–rural relationship in Guangdong Province, this paper constructs an analysis framework of urban and rural coordination development. Using the data of 19 administrative units above prefecture level in Guangdong Province, this paper studies the space–time evolution of urban and rural coordination development during 2000–2015 through Principal Component Analysis (PCA) and Exploratory Spatial Data Analysis (ESDA) and explores the influencing factors and driving forces behind it.
