“…Nearly all previous spatially explicit econometric studies of land-use change have necessarily relied upon crosssectional analyses because of data availability constraints. In a meta-analysis of 117 such studies (40), only three have previously used panel methods (39,41,42). This paper is at the forefront of what is likely to be a proliferation of panel econometric analyses enabled by the recent availability of reliable, annual, globally consistent data on patterns of forest loss (28).…”

To reduce greenhouse gas emissions from deforestation, Indonesia instituted a nationwide moratorium on new license areas (“concessions”) for oil palm plantations, timber plantations, and logging activity on primary forests and peat lands after May 2011. Here we indirectly evaluate the effectiveness of this policy using annual nationwide data on deforestation, concession licenses, and potential agricultural revenue from the decade preceding the moratorium. We estimate that on average granting a concession for oil palm, timber, or logging in Indonesia increased site-level deforestation rates by 17–127%, 44–129%, or 3.1–11.1%, respectively, above what would have occurred otherwise. We further estimate that if Indonesia’s moratorium had been in place from 2000 to 2010, then nationwide emissions from deforestation over that decade would have been 241–615 MtCO2e (2.8–7.2%) lower without leakage, or 213–545 MtCO2e (2.5–6.4%) lower with leakage. As a benchmark, an equivalent reduction in emissions could have been achieved using a carbon price-based instrument at a carbon price of $3.30–7.50/tCO2e (mandatory) or $12.95–19.45/tCO2e (voluntary). For Indonesia to have achieved its target of reducing emissions by 26%, the geographic scope of the moratorium would have had to expand beyond new concessions (15.0% of emissions from deforestation and peat degradation) to also include existing concessions (21.1% of emissions) and address deforestation outside of concessions and protected areas (58.7% of emissions). Place-based policies, such as moratoria, may be best thought of as bridge strategies that can be implemented rapidly while the institutions necessary to enable carbon price-based instruments are developed.

“…Advances in land use science, however, have been limited by a paucity of high-quality panel data that relate evolving household characteristics with changing land use and land cover (18; for exceptions, see refs. 19,20,21) and attention to the potential role of asset path dependency in land use/ cover change.…”

In this article we illustrate how fine-grained longitudinal analyses of land holding and land use among forest peasant households in an Amazonian village can enrich our understanding of the poverty/ land cover nexus. We examine the dynamic links in shifting cultivation systems among asset poverty, land use, and land cover in a community where poverty is persistent and primary forests have been replaced over time-with community enclosure-by secondary forests (i.e., fallows), orchards, and crop land. Land cover change is assessed using aerial photographs/satellite imagery from 1965 to 2007. Household and plot level data are used to track land holding, portfolios, and use as well as land cover over the past 30 y, with particular attention to forest status (type and age). Our analyses find evidence for two important types of "land-use" poverty traps-a "subsistence crop" trap and a "short fallow" trap-and indicate that the initial conditions of land holding by forest peasants have long-term effects on future forest cover and household welfare. These findings suggest a new mechanism driving poverty traps: insufficient initial land holdings induce land use patterns that trap households in low agricultural productivity. Path dependency in the evolution of household land portfolios and land use strategies strongly influences not only the wellbeing of forest people but also the dynamics of tropical deforestation and secondary forest regrowth.poverty dynamics | land use and land cover change | path dependency | agroforestry | Peruvian Amazon A central problem in the drive for sustainability is how human welfare and land use are related to one another and influence prospects for growth without jeopardizing Earth's life support systems. Although recent research has advanced significantly our understanding of poverty dynamics and of land use/cover change, such work has proceeded essentially on separate scientific fronts and has yet to be united under the umbrella of sustainability science.The work of economists points to the existence of persistent poverty traps, whereby households, communities, regions, and even countries are caught in self-reinforcing economic equilibria that perpetuate low standards of living (1-5). In peasant farming and pastoral communities, researchers using rich microlevel panel data find that households can face dynamic asset poverty traps, unable to accumulate sufficient land and equipment (or livestock), for example, to adopt more productive agricultural systems and thereby move out of poverty (6-9). Such poverty traps reflect significant path dependency in asset accumulation, i.e., initial conditions of asset holding matter much for households' future welfare. Although the crucial roles of land holdings for peasant farmers have been emphasized and extensively studied (10, 11), the notion of "land-size" poverty traps-whereby small initial land holdings limit future prospects for peasant farmersremain little studied empirically. Moreover, the potentially important role of different land types and lan...

Pensando de forma integrada a relação população-ambiente, o artigo aborda os estudos sobre dinâmica populacional e mudança no uso e cobertura da terra, com foco na contribuição e nos desafios da Demografia. Aproximando-se do tema em meados dos anos 1990, a Demografia teve como principal contribuição destacar a importância dos componentes populacionais nos modelos, antes, colocados como secundários e sob uma perspectiva simples. Demógrafos brasileiros dedicados a questões ambientais, embora tivessem prioritariamente a temática urbana no seu escopo, colaboraram de maneira indireta para a desenvoltura do campo, ao proporem uma releitura sobre relações população-ambiente. O artigo parte do caso da Amazônia brasileira, mostrando como a população foi explorada nas teorias sobre mudanças nos usos e coberturas da terra, passando pelo viés do crescimento populacional durante o período de fronteira agrícola, o modelo de ciclo de vida do domicílio (fecundidade e composição do domicílio) na década de 1990 e, mais recentemente, o enfoque no componente migratório. Para a Demografia, aponta-se como essencial o aprofundamento nos elementos demográficos que não o volume e a inclusão do espaço e seus efeitos. Para a construção da Ciência da Mudança da Terra, destacam-se a incorporação de dinâmicas urbanas nas investigações, a adoção de uma metodologia multiescalar e o exercício do diálogo entre as diversas disciplinas, incorporando mais sistematicamente a contribuição da Demografia.Palavras-chaves: Demografia. Mudança no uso e cobertura da terra, Amazônia.
