Abstract Voluntary sustainability standards and certification offer a promising mechanism to mitigate the severe negative impacts of agricultural expansion intensification on tropical biodiversity. From conservation standpoint, agroforestry crops, especially coffee cocoa, is particular interest given potentially high biodiversity value systems substantial market penetration cocoa in recent years. Here, we review experience with certification, summarize evidence impacts, explore future needs....
Approaches to integrated landscape management are currently garnering new interest as scientists, policymakers, and local stakeholders recognize the need increase multi-functionality of agricultural landscapes for food production, livelihood improvement, ecosystem conservation. Such approaches have been attempted in many parts Latin America Caribbean (LAC) but date there has no systematic assessment their characteristics, outcomes, limitations. To fill this gap, we surveyed participants...
Agroecological intensification (AEI) integrates ecological principles and biodiversity management into farming systems with the aims of increasing farm productivity, reducing dependency on external inputs, sustaining or enhancing ecosystem services. This review develops an analytic framework to characterize fulfilment these objectives by documenting co-occurrence positive, neutral, negative outcomes for crop yield nine regulating We provide illustrative examination framework, evaluating...
Zero-deforestation commitments are a type of voluntary sustainability initiative that companies adopt to signal their intention reduce or eliminate deforestation associated with commodities they produce, trade, and/or sell. Because each company defines its own zero-deforestation commitment goals and implementation mechanisms, content varies widely. This creates challenges for the assessment effectiveness. Here, we develop criteria assess potential effectiveness at reducing within supply...
Sustainability standards and certification serve to differentiate provide market recognition goods produced in accordance with social environmental good practices, typically including practices protect biodiversity. Such have seen rapid growth, tropical agricultural commodities such as cocoa, coffee, palm oil, soybeans, tea. Given the role of sustainability influencing land use hotspots biodiversity, deforestation, intensification, much could be gained from efforts evaluate increase...
Abstract Voluntary sustainability standards have increased in uptake over the last decade; here, we explore their potential contribution to biodiversity conservation and other aspects of agricultural sustainability. We reviewed content 12 major crop quantified global coverage. All included some provisions for protection biodiversity, but only identified two with criteria that prohibited all deforestation. found records certified cropland 133 countries, estimated area by 11% (range 8.8–13.5%)...
On our current trajectory, severe disruptions to national and regional food systems are highly likely happen - the main question is when. This report, commissioned by UN DESA as a strategic input SD21 Rio discussions, focuses on vital areas offers collection of up date information trends for global Food Agriculture systems.
Voluntary sustainability standards have expanded dramatically over the last decade. In agricultural sector, such aim to ensure environmentally and socially sustainable production of a variety commodity crops. However, little is known about where certification operates whether certified lands are best located for conserving world's most important biodiversity benefiting vulnerable producers. To examine these questions we developed first global map crop certification, synthesizing data from...
Environmental challenges are complex and require expertise from multiple disciplines. Consequently, there is growing interest in interdisciplinary environmental research that integrates natural social science, an often arduous undertaking. We surveyed researchers interested experienced at the human—environment interface to assess perspectives on research. Integrative has eluded many of our respondents, whose efforts better described as additive multidisciplinary The respondents identified...
A number of governance mechanisms address socio-environmental challenges associated with commodity agriculture in tropical forested countries. Governance that prove effective one agricultural sector are often applied to other sectors as well. For example, voluntary certification programs have been adopted by producers commodities diverse beef, coffee, palm oil, and soy. However, there substantial differences the extent which scale up achieve impact different sectors. This paper analyzes how...
Significance Voluntary sustainability standards (VSS) may be an effective way to reduce the negative impacts of agriculture at regional global scales. Here, we present approach that highlights potential VSS some externalities associated with production. To illustrate this potential, show could environmental from growing sugarcane. Further, most benefit comes targeting just 10% production area. realize these gains, incentives for adoption need sufficient cover costs criteria compliance....
Suburban, exurban, and rural development is a leading cause of biodiversity loss natural resource degradation in the United States. In response to this threat, conservation has been advanced as way combine land with functional protection for resources. This article provides review, analysis, ecological critique four principal types development: (1) buyer projects, (2) limited (3) subdivisions, (4) conservation-oriented planned projects. Each approach can contribute landscape-scale...
Abstract: Conservation development projects combine real-estate with conservation of land and other natural resources. Thousands such have been conducted in the United States countries through involvement private developers, landowners, trusts, government agencies. Previous research has demonstrated potential value for conserving species, ecological functions, resource values on lands, especially when traditional sources funding are not available. Nevertheless, aggregate extent effects were...
Global development of the biofuel sector is proceeding rapidly, driven by national policy mandates, government subsidies, and profit opportunities for farmers, agribusiness energy companies. To date, most investment in—and dialogue on—biofuels has focused on large-scale production liquid transport fuels. A smaller set efforts explored potential biofuels to promote rural reducing poverty among world's two billion poorest people. Here, we consider these diverse approaches goals ecoagriculture:...
