Home gardens are land use units embedded in a larger land use system, in this case in Candelaria Loxicha, Oaxaca, Mexico. Using a combination of qualitative and quantitative methods, we investigated how home gardens are integrated into local farming practices and how these influence biodiversity. Our findings suggest that home gardens harbour high levels of biodiversity, which are maintained and enriched by farmers' practices, particularly plant and seed exchange. Plant diversity is higher in younger home gardens and in home gardens where owners actively exchange plant material with other people. Through plant exchange, seed storage, and the dispersion of seeds and plants in different land uses, farmers encourage plant diversity and consequently increase the resilience of their farming system in changing climatic, demographic and economic conditions. Both men and women participate in the establishment, care and management of home gardens, but they are responsible for different plants and home garden functions. For economic reasons, the inhabitants of Candelaria Loxicha are increasingly engaging in international migration. Migrants, upon their return bring new ideas and plants that might transform the rural landscape.

Important transformations are underway in tropical landscapes in Latin America with implications for economic development and climate change. Landscape transformation is driven not only by national policies and markets, but also by global market dynamics associated with an increased role for transnational traders and investors. National and global trends affect a disparate number of social, political and economic interactions taking place at the local level, which ultimately shapes land-use and socio-economic change. This paper reviews five different trajectories of landscape change in tropical Latin America, and discusses their implications for development and conservation: (1) Market-driven growth of agribusiness; (2) expansion and modernization of traditional cattle ranching; (3) slow growth of peasant agriculture; (4) logging in production forest frontiers; and (5) resurgence of agro-extractive economies. Contrasting trade-offs between economic development and forest conservation emerge across these OPEN ACCESSForests 2011, 2 2 landscapes, calling for nuanced policy responses to manage them in the context of climate change. This discussion sets the background to assess how reduction of emissions from deforestation and forest degradation and enhancing carbon stocks (REDD+) aims should be better aligned with current landscape trajectories and associated actors to better address climate-change mitigation in forest landscapes with effective and equitable outcomes.

In this paper, we ask what the effects of migration and remittances are on land tenure, agriculture and forests, based on empirical evidence from four rural communities in Guatemala. Our results suggest that remittances improve migrant families' access to agricultural land which -depending on the context -fosters more equitable local land distribution patterns or land concentration by migrant families. Changes in the political economy of the country also combine to stimulate these patterns, while remittances contribute to secure land rights held by migrant households. But even though migrant households are acquiring more land, the trend does not change the traditional pattern of land distribution in the country. Regarding forests, significant changes were not observed in two of the communities, while in one we observed forest decline and in the last, forest recovery. A trend away from reliance on the land for survival results in forest recovery.

Indigenous peoples around the world and particularly in Latin America are struggling to strengthen their control over land and the territories they inhabit. The strengthening of rights has come as a result of multiple processes both at national and global levels, in which the role and responsibilities of states have been transformed. Transnational processes challenge the presumed association between nation-states, sovereignty and territoriality. One of these challenges comes from international initiatives such as REDD. Global REDD in its broadness and national REDD in its uncertain early phases, represent opportunities for private actors to negotiate with holders of land rights. In the Amazon, indigenous peoples' territories, given their wide extension and that they are mainly forested areas, become interesting for all sorts of REDD actors. However, despite legal and rhetoric recognition of indigenous land rights' effective recognition is still lacking. In this paper I will focus on one particular type of actor, so called "carbon cowboys" a term coined by journalists to signify actors who are willing to push the limits of established negotiation mechanisms to gain control over forest areas. I will focus on carbon cowboys' practices and the responses from indigenous peoples in Colombia to highlight a common claim across the region, namely better state presence and regulation. The response from indigenous peoples' organizations indicates that although territorial control is an important achievement, some form of state intervention is required to protect their rights in an uncertain REDD terrain.

The local business elites of El Salvador were generally in favour of the peace agreement and supported its negotiation and implementation in 1992, while in Guatemala the private sector reluctantly supported the peace process and, after the peace agreements were signed in 1996, the private sector sought to obstruct parts of its implementation. In the aftermath of the peace accords, business elites united around an ideology espousing a minimal state and a focus on market solutions to social problems. Although welcoming the security-related measures in the peace accords, business elites have often obstructed transformations towards more inclusive and democratic societies. However, in recent years there has been a change in discourse among influential business associations towards recognition of the need for strong state institutions and the need for institutionalised mechanisms for dialogue to find solutions to social problems. In this article, we seek to shed light on the significance of this discursive turn for continued peace-building.
