TLDR
In this article, a framework for considering compositional heterogeneity (the number and proportions of different cover types) and configurational heterogeneity, the spatial arrangement of cover types, is proposed.Abstract:
Biodiversity in agricultural landscapes can be increased with conversion of some production lands into 'more-natural'- unmanaged or extensively managed - lands. However, it remains unknown to what extent biodiversity can be enhanced by altering landscape pattern without reducing agricultural production. We propose a framework for this problem, considering separately compositional heterogeneity (the number and proportions of different cover types) and configurational heterogeneity (the spatial arrangement of cover types). Cover type classification and mapping is based on species requirements, such as feeding and nesting, resulting in measures of 'functional landscape heterogeneity'. We then identify three important questions: does biodiversity increase with (1) increasing heterogeneity of the more-natural areas, (2) increasing compositional heterogeneity of production cover types and (3) increasing configurational heterogeneity of production cover types? We discuss approaches for addressing these questions. Such studies should have high priority because biodiversity protection globally depends increasingly on maintaining biodiversity in human-dominated landscapes.read more

TL;DR: This review uses knowledge gained from human‐modified landscapes to suggest eight hypotheses, which it hopes will encourage more systematic research on the role of landscape composition and configuration in determining the structure of ecological communities, ecosystem functioning and services.

Biodiversity and resilience of ecosystem functions

TL;DR: A range of mechanisms underpinning the resilience of ecosystem functions across three ecological scales are identified and biodiversity, encompassing variation from within species to across landscapes, may be crucial for the longer-term resilience ofcosystem functions and the services that they underpin.

Conservation agriculture and ecosystem services: An overview
TL;DR: The potential and limitations of conservation agriculture for low productivity, small-scale farming systems in Sub Saharan Africa and South Asia is discussed in this article. But, the authors highlight some research priorities for ecosystem services in conservational agriculture.

Ecological Responses to Habitat Fragmentation Per Se
TL;DR: Most significant fragmentation effects were positive, irrespective of how the authors controlled for habitat amount, the measure of fragmentation, the taxonomic group, the type of response variable, or the degree of specialization or conservation status of the species or species group.

Remote sensing for agricultural applications: A meta-review
TL;DR: In this paper, the authors present the agronomical variables and plant traits that can be estimated by remote sensing, and describe the empirical and deterministic approaches to retrieve them, and provide a synthesis of the emerging opportunities that should strengthen the role of remote sensing in providing operational, efficient and long-term services for agricultural applications.

TL;DR: Global croplands, pastures, plantations, and urban areas have expanded in recent decades, accompanied by large increases in energy, water, and fertilizer consumption, along with considerable losses of biodiversity.
Journal ArticleDOI
Effects of Habitat Fragmentation on Biodiversity
TL;DR: In this article, the authors suggest that the term "fragmentation" should be reserved for the breaking apart of habitat, independent of habitat loss, and that fragmentation per se has much weaker effects on biodiversity that are at least as likely to be positive as negative.

Landscape perspectives on agricultural intensification and biodiversity – ecosystem service management
TL;DR: In this article, the negative and positive effects of agricultural land use for the conservation of biodiversity, and its relation to ecosystem services, need a landscape perspective, which is difficult to be found in the literature.

Farmland biodiversity: is habitat heterogeneity the key?
TL;DR: In this paper, the authors argue that the loss of ecological heterogeneity at multiple spatial and temporal scales is a universal consequence of multivariate agricultural intensification and that future research should develop cross-cutting policy frameworks and management solutions that recreate that heterogeneity as the key to restoring and sustaining biodiversity in temperate agricultural systems.
