Global food security requires increased crop productivity to meet escalating demand1–3. Current food production systems are heavily dependent on synthetic inputs that threaten the environment and human well-being2,4,5. Biodiversity, for instance, is key to the provision of ecosystem services such as pest control6,7, but is eroded in conventional agricultural systems. Yet the conservation and reinstatement of biodiversity is challenging5,8,9, and it remains unclear whether the promotion of… 
Intensification for redesigned and sustainable agricultural systems
Sustainable intensification (SI) comprises agricultural processes or systems in which production is maintained or increased while progressing toward substantial enhancement of environmental outcomes, and incorporates these principles without the cultivation of more land and loss of unfarmed habitats and with increases in system performance that incur no net environmental cost.
Establishing next-generation pest control services in rice fields: eco-agriculture
It is indicated that manipulating habitat for natural enemies in rice landscapes enhances pest suppression and maintains equal yields while reducing the need for insecticide use in crop fields.
Innovation and diversification through niche crops : potential and suitability for Switzerland
Globally, agriculture has to diversify to adapt to climate change. Many studies have shown that crop diversification can improve climate resilience of agricultural systems, reduce pesticide
Reducing Pesticides and Increasing Crop Diversification Offer Ecological and Economic Benefits for Farmers—A Case Study in Cambodian Rice Fields
While withholding from using pesticides did not result in a decrease in yield in EE and control treatments, parasitoid abundance was higher in both treatments during the wet season, and the benefit–cost ratio was highest for EE andControl treatments.
Elements of agroecological pest and disease management
The development of large-scale monocropped agrisystems has facilitated increased problems with pests and diseases, perpetuating the reliance of farmers on synthetic pesticides. The economic success
Increasing plant diversity with border crops reduces insecticide use and increases crop yield in urban agriculture
Monitoring data collected from rice fields in 34 community farms in mega-urban Shanghai, China from 2001 to 2015 shows that the presence of a border crop of soybeans and neighboring crops, both without weed control, increased invertebrate predator abundance, decreased the abundance of pests and dependence on insecticides, and increased grain yield and economic profits.
A Framework to Assess Forest-Agricultural Landscape Management for Socioecological Well-Being Outcomes
Global demand for agricultural products continues to grow. However, efforts to boost productivity exacerbate existing pressures on nature, both on farms and in the wider landscape. There is
Investigating the (Mis)Match between Natural Pest Control Knowledge and the Intensity of Pesticide Use
The match (or mismatch) between the intensity of pesticide use and the availability of knowledge on the ecosystem service of natural pest control across various crop systems is investigated to suggest that a major increase of interest in agroecological research towards crops with high insecticide input would help meet knowledge needs for a timely ecointensification of agriculture.


Resource-conserving agriculture increases yields in developing countries.
The extent to which 286 recent interventions in 57 poor countries covering 37 M ha have increased productivity on 12.6 M farms while improving the supply of critical environmental services is shown.
Comparing the yields of organic and conventional agriculture
A comprehensive meta-analysis is used to examine the relative yield performance of organic and conventional farming systems globally, and shows that, overall, organic yields are typically lower than conventional yields.
Global food demand and the sustainable intensification of agriculture
Per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960 and forecasts a 100–110% increase in global crop demand from 2005 to 2050.
Toward a more resilient agriculture
Agriculture is a key driver of change in the Anthropocene. It is both a critical factor for human well-being and development and a major driver of environmental decline. As the human population
Organic agriculture promotes evenness and natural pest control
The argument that rejuvenation of ecosystem function requires restoration of species evenness, rather than just richness, is strengthened, as organic farming potentially offers a means of returning functional evenness to ecosystems.
Synthesis, part of a Special Feature on A Social-Ecological Analysis of Diversified Farming Systems: Benefits, Costs, Obstacles, and Enabling Policy Frameworks Ecosystem Services in Biologically Diversified versus Conventional Farming Systems: Benefits, Externalities, and Trade-Offs
We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs—such as maintenance of
Reconciling Food Production and Biodiversity Conservation: Land Sharing and Land Sparing Compared
Compared crop yields and densities of bird and tree species across gradients of agricultural intensity in southwest Ghana and northern India, land sparing is a more promising strategy for minimizing negative impacts of food production, at both current and anticipated future levels of production.
Does plant diversity benefit agroecosystems? A synthetic review.
This first use of meta-analysis to evaluate the effects of diversification schemes, a potentially more powerful tool than tallies of significant positive and negative outcomes (vote-counting), revealed stronger overall effects on all parameters measured compared to previous reviews.
