Conventional land‐use intensification reduces species richness and increases production: A global meta‐analysis

Global Change Biology, Journal Year: 2019, Volume and Issue: 25(6), P. 1941 - 1956

Published: April 9, 2019

Most current research on land-use intensification addresses its potential to either threaten biodiversity or boost agricultural production. However, little is known about the simultaneous effects of and yield. To determine responses species richness yield conventional intensification, we conducted a global meta-analysis synthesizing 115 studies which collected data for both variables at same locations. We extracted 449 cases that cover variety areas used (crops, fodder) silvicultural (wood) found that, across all production systems groups, successful in increasing (grand mean + 20.3%), but it also results loss (-8.9%). analysis sub-groups revealed inconsistent results. For example, small steps within low intensity did not affect richness. Within high-intensity losses were non-significant gains substantial (+15.2%). Conventional medium highest increase (+84.9%) showed largest (-22.9%). Production differed their magnitude response, with insignificant changes crop (-21.2%). In addition, this identifies lack collect robust (i.e. beyond richness) sites provide quantitative information intensity. Our findings suggest many cases, drives trade-off between often significantly different from zero, suggesting even can result increases without coming expense loss. These should guide future close existing gaps understand circumstances required achieve such win-win win-no-harm situations agriculture.

The contribution of small-scale food production in urban areas to the sustainable development goals: a review and case study

Sustainability Science, Journal Year: 2020, Volume and Issue: 15(6), P. 1585 - 1599

Abstract Food production depends upon the adequate provision of underpinning ecosystem services, such as pollination. Paradoxically, conventional farming practices are undermining these services and resulting in degraded soils, polluted waters, greenhouse gas emissions massive loss biodiversity including declines pollinators. In essence, is it relies upon. Finding alternative more sustainable ways to meet growing food demands which simultaneously support one biggest challenges facing humanity. Here, we review potential urban peri-urban agriculture contribute production, using 17 development goals set by United Nations General Assembly a framework.

“Insectageddon”: A call for more robust data and rigorous analyses

Global Change Biology, Journal Year: 2019, Volume and Issue: 25(6), P. 1891 - 1892

Published: March 1, 2019

As members of that subset the human population who love insects, we have been alarmed by a recent publication reporting their global decline and impending extinction (Sánchez-Bayo & Wyckhuys, 2019), accompanying media furore. Indeed, there has growing tide concern over magnitude potential consequences diminishing insect populations (e.g., Hallmann et al., 2017; Lister Garcia, 2018). However, respectfully suggest accounts demise insects may be slightly exaggerated. Bad things are happening—we agree—but this is not whole story. We call for hard-nosed, balanced, numerical analysis changes taking place, calm even-handed interpretation changes, rather than rushing headlong into hyperbole apocalypse. Reports declines come as no surprise to entomologists; familiar territory many decades (Leather, 2019). The latest article Sánchez-Bayo Wyckhuys (2019) makes substantial valuable contribution field, bringing together individual studies in one review. considerable uncertainties biases remain. A key problem stems from "Methodology" section, which states "…. performed search on online Web Science database using keywords [insect*] AND [declin*] [survey]…..." Using term immediately meta-analysis toward exaggerated estimates rates, even assuming underlying bias literature. An unbiased review literature would still find declines, but based "unidirectional" methodology credible.

Nearly all "disappearances" species reported represent losses sites or regions, it requires quite different data calculations extrapolate at larger scales.

Soil fertility provides the foundation for nutritious food production and resilient sustainable livelihoods. A comprehensive survey summit meeting were conducted with aims of understanding barriers to enhancing soil in sub-Saharan Africa providing evidence-based recommendations. The focus regions West Africa, East Great Lakes region, Ethiopia. Overall recommendations developed four emerging themes: (1) strengthening inorganic fertilizer-based systems, (2) access use quality organic inputs, (3) capacity building along entire knowledge-transfer value chain, (4) farming systems research development across biophysical socio-economic factors. process methodology prioritizing these makes findings useful setting out action plans future investments strategies. Access fertilizer, its use, related implementation issues prominent considerations; nevertheless, solutions identified as equally important natural resources. management initiatives should on holistic covering both aspects chain actors creating an enabling environment adoption. broader view improvement using all available options including sources nutrients system approaches are highly recommended.
