The Millennium Development Goals have led to tangible progress in many developing countries. Once adopted, the United Nations' new global Sustainable Development Goals will additionally require industrialized countries to implement such standards beginning in 2016. But the world's first comprehensive stocktaking shows that most industrialized nations are a long way from serving as role models for sustainable development.

China's past economic development model has not been sustainable, at least in environmental terms. In recent years, the Chinese government has dedicated considerable time, planning energy, policy and rhetoric to "green" issues. However, there is a risk that this trend will be stalled by struggles related to pending economic problems and the upcoming leadership transition. Consequently, the international community should acknowledge China’s achievements in terms of environmental policy and cooperation as one way of serving the global public interest.

This brochure deals with policies and policy instruments needed to promote sustainable development in mountain areas. The first part presents an overview of key issues in mountain development, and principles and strategies that should be adopted. Each principle contains a checklist for policy-makers. The second part presents national and regional case studies of successful approaches and initiatives relating to mountain policy from all over the world. The brochure concludes with a call for multi-level initiatives and partnerships. This full-colour publication is part of the Mountains of the World series. It was prepared for the 2002 World Summit on Sustainable Development in Johannesburg by an international panel of experts coordinated by CDE. It was commissioned and funded by the Swiss Agency for Development and Cooperation (SDC).

In September 2015, the UN Member States are expected to commit to an ambitious new set of global goals for a new era of sustainable development. Achieving them will require an unprecedented joint effort on the part of governments at every level, civil society and the private sector, and millions of individual choices and actions. To be realised, the SDGs will require a monitoring and accountability framework and a plan for implementation. A commitment to realise the opportunities of the data revolution should be firmly embedded into the action plan for the SDGs, to support those countries most in need of resources, and to set the world on track for an unprecedented push towards a new world of data for change.

This, the sixty-eighth edition of the Economic Survey of Latin America and the Caribbean, which corresponds to the year 2016, consists of three parts. Part I outlines the region’s economic performance in 2015 and analyses trends in the first half of 2016, as well as the outlook for the rest of the year. It examines the external and internal factors influencing the region’s economic performance and highlights some of the macroeconomic policy challenges that have arisen in an external context of weak growth and high levels of uncertainty. Part II analyses the challenges that the countries of Latin America and the Caribbean face at the domestic and international levels in mobilizing financing for development. On the domestic front, slower growth and tighter fiscal restrictions pose significant challenges for the mobilization of resources. Externally, the classification of many of the region’s countries in the middle-income category limits their access to concessional external financing or international support. Part III of this publication may be accessed on the web page of the Economic Commission for Latin America and the Caribbean (www.eclac.org). It contains the notes relating to the economic performance of the countries of Latin America and the Caribbean in 2015 and the first half of 2016, together with their respective statistical annexes. The cut-off date for updating the statistical information in this publication was 30 June 2016.

Rainforests in eastern Australia have been extensively cleared over the past two centuries. In recent decades, there have been increasing efforts to reforest some of these cleared lands, using a variety of methods, to meet a range of economic and environmental objectives. However, the extent to which the various styles of reforestation restore structure, composition and ecological function to cleared land is not presently understood. In this study, we develop and apply a method for quantifying the structural attributes of reforestation sites in tropical and subtropical Australia. The types of reforestation studied were plantation monocultures, mixed-species cabinet timber plots, diverse restoration plantings and unmanaged regrowth. Two age classes of reforestation were examined: 'young' (5-22 years), incorporating sites from all categories, and 'old' (30-70 years), in which only monoculture plantations and regrowth were represented. A total of 104 sites were surveyed including reference sites in intact rainforest and pasture. Intact rainforest was characterised by a suite of complex structural features including abundant special life forms (vines, epiphytes, hemi-epiphytes and strangler figs), a dense stand of trees in a range of size classes, a closed canopy, a shrubby understorey and a well-developed ground layer of leaf litter and woody debris. These features were lost on conversion to pasture. While all types of reforestation returned some elements of structural complexity to cleared land, young plantation monocultures, cabinet timber plots and young regrowth had a relatively simple structure. These sites typically had a low density of woody stems, a relatively open canopy and grassy ground cover, and lacked large trees, coarse woody debris and most special life forms. Restoration plantings and old regrowth were more complex, with a high density of woody stems, a relatively closed canopy and shrubby understorey. Old monoculture plantations in the tropics had acquired many of the structural attributes of intact forest, however this was not the case in the subtropics, where plantations were subject to more intensive management. The marked differences in structural complexity between sites suggest that the different types of reforestation practiced in eastern Australia are likely to vary considerably in their value as habitat for rainforest biota.
