Agricultural technologies have long been promoted by governments and development organizations as effective ways to increase farm productivity reduce poverty. However, adoption of many seemingly beneficial remains low. Empirical studies attempt identify the motivation for based on differences in characteristics between adopters non-adopters. This study investigates variables that regularly explain across contexts using a meta-analysis 367 regression models from published literature. We find...
The meta-analysis dataset presented is a convenience sample from 218 separate studies of agricultural technology adoption in Africa, Asia, and Latin America. Each study uses survey data to estimate form multiple regression (dependent variable) with diverse array predictor variables. Fifteen variable categories are included this dataset: Age, education, gender, household size, farming experience, land soil fertility, slope, distance inputs/outputs, access credit, tenure, livestock ownership,...
Abstract. There are few multi-decadal observations of atmospheric aerosols worldwide. This study applies global hourly visibility (Vis) at more than 3000 stations to investigate historical trends in haze over 1945–1996 for the US, and 1973–2013 Europe eastern Asia. A comprehensive data screening processing framework is developed applied minimize uncertainties construct monthly statistics inverse (1/Vis). includes removal relatively clean cases with high uncertainty, change point detection...
Abstract Excessively low stream flows harm ecosystems and societies, so two key goals of low‐flow hydrology are to understand their drivers predict severity frequency. We show that linear regressions can accomplish both across diverse catchments. analyze 230 unregulated moderate high relief catchments rainfall‐dominated, hybrid, snowmelt‐dominated, glacial regimes in British Columbia, Canada, with drainage areas spanning 5 orders magnitude from 0.5 55,000 km 2 . Summer decreasing...
Chinook salmon (Oncorhynchus tshawytscha) are a keystone species for many ecosystems of western North America, culturally and spiritually significant Indigenous Peoples, underpin multi-million dollar industry. However, in recent years extreme summer streamflow droughts have disrupted migration rearing patterns. Climate change is driving hydrologic changes throughout the region, but future to low flows remain highly uncertain. Here we study 375 near-natural catchments habitat range from...
Abstract Groundwater, Earth’s largest nonfrozen freshwater reservoir, is vital for water supply security. Groundwater models help to manage complex domestic, agricultural, and industrial demands while preserving ecosystem health under climate change. The community-driven groundwater model portal (GroMoPo) hosts metadata analyse biases distribution of models. Over 450 are currently featured on GroMoPo, with most from high-GDP countries at local-to-regional scales. GroMoPo initiative addresses...

Excessively low stream flows harm ecosystems and societies, so two key goals of low-flow hydrology are to understand their drivers predict severity frequency. We show that simple linear regressions can accomplish both across diverse catchments. analyse 230 unregulated moderate high relief catchments rainfall-dominated, hybrid, snowmelt-dominated, glacial regimes in British Columbia, Canada, with drainage areas spanning 5 orders magnitude from 0.5 55,000 km2. find summer decreasing...

Background and Objective Laser osteotomy bears well‐identified advantages over conventional techniques. However, lack of depth control collateral thermal damage are barriers to wide clinical implementation. Flexible fiber delivery economical benefits ytterbium‐doped lasers make them desirable for laser osteotomy. In this work, we demonstrate automated bone ablation with a 1,070 nm industrial‐scale create 3D target structures minimal side‐effects. Materials Methods Fresh dry ex vivo cortical...
Agricultural technology transfer to people in the developing world is a potentially powerful tool raise productivity and improve livelihoods. Despite this, many technologies are not adopted by their intended beneficiaries. Qualitative studies have identified guidelines follow design dissemination of agricultural technology, but there has been comparatively little synthesis quantitative adoption. This study presents meta-analysis adoption world. The results confirm most earlier findings, cast...
The increasing number and quality of numerical groundwater models worldwide represent a great source knowledge for local, regional, international scientists as well water managers decision makers. This development is facilitated by recent advancements in computational tools access to open software. At the same time, scientific journals stress importance sharing model codes data upon publishing, setting new publishing standard. Altogether, these developments modelling field create richer more...
On-farm experimentation is an essential part of aquacultural product development, but experimental designs that are commonly used for intensive commercial aquaculture usually not suitable earthen pond aquaculture, particularly in smallholder contexts. Guidance on-farm testing aeration technologies similarly lacking. We therefore propose design (a cross-over experiment) has previously been applied to and we demonstrate its use as the field a novel solar device Bangladesh. The experiment was...
