Climate change projections internationally accepted as being reliable indicate that most countries in the Pacific region will suffer large-scale negative impacts from climate change. These impacts are likely to include elevated air and sea-surface temperatures, increasingly unpredictable rainfall patterns, rising sea levels, and intensification of extreme weather events such as tropical cyclones and El Niño-related droughts.

The costs of doing nothing about land degradation are several times higher than the costs of taking action to reverse it. Despite the crucial role land plays in human welfare and development, investments in sustainable land management are low, especially in developing countries. These findings come from the book, Economics of Land Degradation and Improvement—A Global Assessment for Sustainable Development, which examines the costs of land degradation and what needs to be done to reverse it.

PUBLISHER'S ABSTRACT: The United Nations Declaration on the Rights of Indigenous Peoples was adopted by the UN General Assembly on 13 September 2007. Since then, the importance of the role that indigenous peoples play in economic, social and environmental conservation through traditional sustainable agricultural practices has been gradually recognized.

The government of the Lao People’s Democratic Republic has made great efforts to halt the rapid decline in forest cover by implementing different policy measures, which include measures: to address the causes of the decline in forest cover; to sustainably manage natural forests; and to regenerate degraded forests. In the last decade, forest cover has continued to decrease at a lower rate of just 1% from 2002 (41.5%) to 2010 (40.3%) at national level; however, there has been a net gain of forests in the northern region.

Thirty years after Cambodia’s ‘democratization’ by the United Nations Transitional Authority (UNTAC), the transition to a market-based economy is raging at full steam. Democracy remains elusive, but policy interventions from Cambodia’s “development partners” color the political, social, and environmental landscapes. This paper attends to the land grabs characteristic of market transitions and to the climate change mitigation strategies currently enhancing conflicts over land and resources in contemporary Cambodia.

In this paper, we present an analysis of the change in household land use following a conservation-driven process of indigenous land titling reform in a Cambodian protected area. In each of the two study villages, we investigated how household land use had changed and the extent of compliance with both legal boundaries of titled areas and community regulations created to govern land use within these areas. A comparison of current household land holdings in each village with those at the start of the tenure reform process indicated a significant increase in household land holdings.

In land systems, equitably managing trade-offs between planetary boundaries and human development needs represents a grand challenge in sustainability oriented initiatives. Informing such initiatives requires knowledge about the nexus between land use, poverty, and environment. This paper presents results from Lao PDR, where we combined nationwide spatial data on land use types and the environmental state of landscapes with village-level poverty indicators. Our analysis reveals two general but contrasting trends.

This study aims to contribute to the understanding of factors influencing the sustainable farmland management in Niger. Specifically, it examines the determinants of adoption of sustainable land management practices including measures to combat erosion, and the use of manure, residues and fertilizer with a view to support the formulation of efficient land use policies based on evidences given fact that the impact of factors influencing farmland management appears to be specific to each context.

In Ethiopia, exclosures in landscapes have become increasingly important to improving ecosystem services and reversing biodiversity losses. The present study was conducted in Gomit watershed, northern Ethiopia, to: (i) investigate the changes in vegetation composition, diversity and aboveground biomass and carbon following the establishment of exclosures; and (ii) analyse the economic returns of aboveground carbon sequestration and assess the perception of local communities on land degradation and exclosures.

Desertification is a threat to human survival and has a major sustainability development impact on environment and socio-economic society. The study area where oasis desertification occurred is located east of the Ebinur Lake region, just west of Junggar Basin in Xinjiang, China. The ecological and environmental issues in the study area are vulnerable and sensitive. The authors of this paper discuss the changes in land desertification that occurred between 1990 and 2010.
