The widely reported claim that smallholders produce 70–80% of the world's food has been a linchpin agricultural development policy despite limited empirical evidence. Recent attempts to reinvestigate this number have lacked raw data on how much produce, and relied model assumptions with unknown biases spatial commodity coverage. We examine variations in crop production by farm size using newly-compiled global sample subnational level microdata censuses covering more countries (n=55) types...
Hundreds of millions the world's poorest people directly depend on smallholder farming systems. These now face a changing climate and associated societal responses. We use mapping literature review to juxtapose fate systems with that other agricultural population groups. Limited direct evidence contrasts impact risk in versus systems, but proxy suggests high vulnerability. Smallholders distinctively adapt shocks stressors. Their future adaptive capacity is uncertain conditional upon severity...
Big data and mobile technology are widely claimed to be global disruptive forces in agriculture that benefit small-scale farmers. Yet the access of farmers this is poorly understood. We show only 24–37% farms <1 ha size served by third generation (3G) or 4G services, compared 74–80% >200 size. Furthermore, croplands with severe yield gaps, climate-stressed locations food-insecure populations have poor service coverage. Across many countries Africa, less than ~40% farming households Internet...
Significance Foreign investors have acquired vast tracts of land globally since the early 2000s, yet food security implications this phenomenon are poorly understood. The ability to close crop yield gaps through commercial agriculture must be weighed against local impacts on access. We combine agricultural, remote sensing, and household survey data with georeferenced information deals examine their production Results point a paradox where simultaneously contribute closing global gap by...
Background Buruli ulcer (BU), one of 17 neglected tropical diseases, is a debilitating skin and soft tissue infection caused by Mycobacterium ulcerans. In Africa, changes in land use proximity to water have been associated with the disease. This study presents first analysis BU at village level southwestern Ghana, where prevalence rates are among highest globally, explores fine medium-scale associations cover comparing patterns both within clusters surrounding landscapes....
Graphics are becoming increasingly important for scientists to effectively communicate their findings broad audiences, but most researchers lack expertise in visual media. We suggest collaboration between and graphic designers as a way forward discuss the results of pilot project test this type collaboration.
Abstract Numerous alternative farming systems are proposed as solutions to the sustainability challenges of today's conventional systems. In this paper, we review production, environmental, and socioeconomic performance three widely discussed promoted systems—organic, smallholder, urban agriculture. We show that both organic smallholder agricultures have some benefits, but also entail important trade‐offs; has environmental livelihood, health, nutritional benefits for producers consumers, is...
In 2011, the number of hungry people in world surpassed one billion for first time. The majority these are largely dependent their food security upon resource-poor smallholder farmers developing or emerging economies. These smallholders depend on informal seed systems 75–90% crop cultivation. Southeast Asia, world's biodiversity hotspots face rapidly dwindling global genetic diversity, is at forefront issues. This article examines activities undertaken by a collaboration researchers and...
This dataset is a cross-country convenience sample of primary data measuring crop production and/or area by farm size for 55 countries that underlies the article entitled "How much world׳s food do smallholders produce?" (DOI: https://doi.org/10.1016/j.gfs.2018.05.002). The harmonized nationally representative with subnational resolution, sourced from agricultural censuses and household surveys. covers 154 species 11 classes, ontologically interoperable other global datasets, such as Food...
Debates concerning how to achieve food security tend fall into one of two camps. The first is that high-technology, market-oriented approaches promise enhance agricultural productivity and improve security. counterargument low-technology approaches, when combined with building social physical infrastructure, are more effective at meeting people’s needs. Using a survey 540 farm households in northern Ghana, we assess the level for smallholders by analyzing influence low-external-input...
This paper examines the current state of agricultural education and training (AET) system in Cambodia provides recommendations for Cambodian institutions policymakers enhancing AET system. We conducted two assessment trips June 2013 January 2014 to analyze Data were collected 53 interviews five focus groups using a modified-SWOT analysis framework. Stakeholder-identified strengths include political economic stability Cambodia, young labor force, increased educational enrollments, new schools...
A few issues regarding the original published version of this article were brought to our attention.In an effort reproduce work, we found need provide some corrections paper.Here report a full re-extraction values from primary literature, re-coding formulae used for standardization, and re-analysis.We note that after effort, main conclusions paper are not substantially affected.The one notable change is no longer find evidence labour being significant explanatory cause inverse size-yield...
Dynamic social relationships can enhance farmer adoption or lead to the rejection of modern seed varieties. Different pathways provide farmers with information about traditional and commercial seeds. Identifying how facilitate different varietal use may reveal informal safety nets indigenous rely on when transitioning While homophilous have been observed stifle farmers’ agricultural innovations, these bonded are basis for exchange. Through relationships, able communicate pertinent risks...
