This international symposium featured three interconnected thematic foci of interdisciplinary research. They focussed on the changes in the extent and intensity of agricultural and forest land use in tropical forest margins and their implications for rural development and for conservation of natural resources such as biodiversity, soils and water. The symposium took place in Goettingen. Almost 130 international authors have contributed a short abstract and their adress.

Since the middle of the last century, rapid population growth and urbanization have led to the encroachment of a large number of natural spaces, resulting in a series of ecological security issues such as environmental pollution, resource depletion and habitat destruction, which have severely challenged global sustainable development. Urban ecological security is an important barrier to urban residents' production and life, the foundation and core of national or regional ecological security, and it is of great significance to promote green development and harmonious coexistence between humans and nature. With global warming, frequent natural disasters and other multifactorial threats, the issue of ecological security in cities as centers of the settlement have become a focus of international attention. However, cities are complex systems with social, economic and natural conditions coupled with each other. Under the overlapping of many factors, the basic problems such as the mechanism of urban development on ecological security have not been fully explained, and there is also a lack of quantitative assessment methods corresponding to urban ecological conditions, let alone simulation and prediction.

Studies of African economic development frequently focus on the daunting challenges the continent faces. From recurrent crises to ethnic conflicts and long-standing corruption, a raft of deep-rooted problems has led many to regard the continent as facing many hurdles to raise living standards. Yet Africa has made considerable progress in the past decade, with a GDP growth rate exceeding five percent in some regions. The African Successes series looks at recent improvements in living standards and other measures of development in many African countries with an eye toward identifying what shaped them and the extent to which lessons learned are transferable and can guide policy in other nations and at the international level. The first volume in the series, African Successes: Governments and Institutions considers the role governments and institutions have played in recent developments and identifies the factors that enable economists to predict the way institutions will function.
