Influence of crop rotation, irrigation, fertilization, and tillage on the aggregate property and soil wind erosion potential in the floodplain of the Yellow River

The floodplain of the Yellow River (FPYR) is threatened by severe soil erosion. Soils are often susceptible to wind erosion owing to their coarse-textures and weak aggregation, yet studies are yet to describe the ability of soils to resist wind erosion in this region. Accordingly, this study aimed to quantify how soil wind erosion potential is affected by soil aggregate properties, such as dry aggregate geometric mean diameter (GMD), aggregate geometric standard deviation (GSD), aggregate stability, and soil bulk density, and to assess the effects of soil type, crop rotation, irrigation, fertilization, and tillage treatments on these aggregate properties in the main wind erosion area across the FPYR. Significant differences in GMD and aggregate stability were found between crop rotation treatments, whereas crop rotation marginally affected the soil bulk density. Further, the impact of management practices on aggregate properties differed for each soil type. The soil aggregate erodible fraction (EF) in the FPYR ranged from 1.14 to 82.73% across sites, with a mean of 26.14% across soil types and management practices, which was lower than that previously reported in other wind erosion regions. We incorporated these measured EFs into the Revised Wind Erosion Equation (RWEQ) to evaluate the wind erosion risk of the FPYR. The results indicated that the central FPYR was more susceptible to wind erosion than the other regions, although the total wind erosion potential in the FPYR was small. Adoption of soil conservation practices could help minimize wind erosion and improve atmospheric quality in the region.

Long-Term Cropping Management Practices Affect the Biochemical Properties of an Alabama Ultisol

Interest in improving the long-term sustainability of agricultural production systems has focused on identifying management practices that promote soil health. No tillage, cover cropping, and amending soils with broiler (Gallus gallus domesticus L.) litter are commonly adopted conservation practices that have been shown to improve soil fertility and crop yield. However, the overall influence of these conservation practices on soil health in the southeastern US are not well understood. Thus, a study was conducted to evaluate the influence of tillage, broiler litter (BL) applications, and cropping systems on soil biochemical properties. Soils were collected from field research plots under long-term management (>than 25 years of tillage, 15 years of broiler litter application, and 15 years of cropping system). Soil microbial biomass, C, N, and P, amidohydrolases, and dissolved organic matter (DOM) were evaluated as indicators of soil health. Adopting tillage and BL into the agricultural management system modified the biochemical parameters of the soils evaluated. Most of these modifications occurred in the 0–5 cm depth. Higher microbial biomass carbon (MBC; 85%) and nitrogen (MBN; 10%) and enzyme activities of asparaginase (65%) and glutaminase (70%) were observed in the 0–5 cm depth under no tillage (NT) compared to conventional tillage (CT), indicating greater biological activities were established in these soil ecosystems. Broiler litter applications increased microbial biomass N and activities of asparaginase and glutaminase in both soil depths. In addition, microbial biomass phosphorus (MBP) was increased following BL application in the 0–5 cm depth. The results suggest that long-term management of NT and BL additions can improve the health of eroded southeastern US soils by altering the soil biochemical parameters.

Examining cover crop agri-environmental program participation: Evidence from a western US farmer survey

Agri-environmental programs (AEPs), which pay farmers to adopt conservation practices, are increasingly important environmental and agricultural policy tools used in both the US and the EU. Despite large budgetary shares allocated in a 20-year application window, several studies identify lower-than-expected environmental outcomes. In the US, reasons for low environmental outcomes include low participation rates, lack of program awareness, and poor targeting levels. Research has identified low levels of awareness and variation in participation across the US in the Environmental Quality Incentives Program (EQIP), the largest working lands program in the US. Using a survey of Western US farmers, this paper provides an analysis of awareness and participation levels in cover crop AEPs in the Western US. Second, this paper analyzes motivations and barriers to participation in cover crop AEPs through the Environmental Quality Incentives Program (EQIP) and the Conservation Stewardship Program (CSP). Third, the paper uses a survey experiment to examine different types of incentives. The results highlight that participation is low due to lack of awareness and policy barriers. Using a logistic regression, predictors of AEP participation include frequent contact with NRCS, having a succession plan, and a positive attitude toward governments’ role in conservation programs. The survey experiment found that non-financial factors, such as more information on cover crops, is an effective policy incentive.

Adoption of conservative agricultural practices among rural Chinese farmers

Excessive use of agrochemicals and the misuse of natural resources severely degrade farmlands. In addition to organic farming, conservative agricultural practices are one of the most viable methods for preventing environmental deterioration. Its adoption has remained relatively modest in developing countries as farmers rely exclusively on synthetic inputs to attain high yields and economic returns. Therefore, this study focuses on the factors that influence farmers’ intention and adoption of conservative agricultural practices. This study extended the Value-Belief-Norm (VBN) framework with a new construct (green trust), and empirically evaluated all fundamental VBN components with their chained relationships among constructs. This cross-sectional study collected quantitative data from 349 farmers using structured interviews. The partial least squares structural equation modeling (PLS-SEM) method was used to statistically evaluate the relationship between the constructs. The analysis demonstrates that both biospheric and altruistic values have a positive impact on the new environmental paradigm, which, in turn, has a significant impact on people’s awareness of consequences and personal norms. Although awareness of consequences had a substantial positive influence on the ascription of responsibilities, it was demonstrated to have a statistically insignificant impact on personal norms. In parallel, the ascription of responsibility had a strong impact on personal norms, which, in turn, positively influenced the intention towards conservative agricultural practices. Remarkably, green trust was found to have the greatest effect on farmers’ intentions. Finally, farmers’ actual adoption was significantly influenced by their intention. The findings of this study will contribute to the strengthening of relevant factors among farmers that may enhance eco-friendly farming practices, develop solutions for regulating the protected utilization of natural resources, and effectively prevent environmental deterioration caused by hazardous agrochemicals. The study will also provide guidance to government regulators and other social organizations in the formulation of effective laws, policies, and strategies for the mass adoption of conservation practices and restoration of agricultural ecosystem balance.

Understanding the Knowledge Level of Farmers towards Climate Smart Agricultural Technologies in Agro-climatic Zones of Tamil Nadu, India

Aims: Although farmers experience various technical, technological, production, labor-related and marketing constraints to carry out agricultural activities, climate change acts as the root cause of several other constraints. Climate change consequences drastically reduce agricultural yield by affecting critical changes of crop growth and questions food and nutritional security; additionally it also imposes economic loss to the country. Hence, to ensure food and nutritional security for the growing population and to ensure sustainable income for the farming community, a farmer has to tackle the consequences of climate change by adoption of CSA technologies Farmer’s knowledge level towards any technology, determine its rate of adoption. Hence, this study aims to assess the knowledge level of farmers towards CSA technologies in Agro-climatic zones of Tamil Nadu.
 Study design: Ex-post facto research design was employed in the study.

 Conclusion: Villupuram, Coimbatore and Tiruvarur farmers had superior knowledge on precision based nutrient management; Namakkal farmers had superior knowledge on use of additives and supplements in livestock feed; Ramanathapuram farmers had superior knowledge on utilization of weather based agro-advisory services; Kanyakumari farmers had superior knowledge on adoption of moisture conservation practices and, The Nilgiris farmers had superior knowledge on adoption of improved seed varieties and use of biofertilizers. Thus, it can be concluded that farmers had superior knowledge on CSA technologies based on their perceived climatic change consequences and their accessibility to location specific technologies.

Evaluate the effectiveness of soil and water conservation interventions in the upper Awash Basin, Ethiopia

AbstractThe central highland of Ethiopia is facing significant challenges due to land degradation, which resulted in changes to the soil's physicochemical properties. This study aims to assess the effectiveness of different conservation methods in enhancing soil physicochemical properties, reducing soil loss and erosion, and maximizing land productivity in Ankober District of Kenseta watershed. For this study, two land uses (conserved and non‐conserved land), three slope positions, and three replication with the soil depth of 0–30 cm were used for undisturbed and disturbed soil samples data collection and analysis. The survey data were collected and evaluated from 106 randomly selecting respondents' households. The results showed significant variation in the mean value of soil physical properties (bulk density, soil moisture content, soil texture) within and between conserved and non‐conserved land. The chemical properties, including pH, EC, exK, CEC, OC, OM, and available P, also changed significant across land management types and along slope position (p < 0.05). Soil managed with stone face soil bund demonstrated significant improvement in soil physicochemical properties. The results were statistically significant difference at (p < 0.05) level of significance. Majority of the respondents' households explained the soil loss and rate of soil erosion were declined and land productivity status increased after the adoption of soil and water conservation practices in the study area. Therefore, proper conservation practices are vital in minimizing the rate of soil loss, ameliorating physical and chemical properties of the soils, and enhancing land productivity.

Farm heterogeneity and leveraging federal crop insurance for conservation practice adoption

AbstractCurrent and proposed policies aim to leverage the Federal Crop Insurance Program (FCIP) to promote conservation practices. This study uses corn farm‐level survey data to inform the effectiveness of targeting FCIP participants. We implement an unsupervised machine learning algorithm to assess what conservation practices are most common among participants. We find that farms that use crop insurance have higher adoption rates for practices that are generally profit‐maximizing. We also calculate nitrogen balance, a yield‐scaled measure of nitrogen fertilizer's potential environmental impact. We find a positive relationship between crop insurance and nitrogen balance closer to the optimum.

Short-Term Contribution of Conservation Practice Implementation to Water Quality Impairments in Small Streams

Voluntary conservation practice adoption is a key strategy to reduce the transport of non-point source pollutants from agricultural lands to downstream ecosystems. This study assessed the short-term (1 year) efficacy of conservation practices to reduce non-point source sediment, nutrient, and fecal indicator bacteria (FIB) transport from working agricultural lands on the Mississippi State University campus, Mississippi State, MS, USA. Water quality was monitored at three treatment sites downstream of the critical resource areas, two of which had paired reference locations. All five sites were monitored for one year pre- and post-conservation practice implementation. Downstream treatment sites generally had higher nutrient and sediment concentrations than upstream reference sites. The results confirmed that the total nitrogen (TN) concentration was reduced post implementation at only the treatment site with the smallest catchment area (p < 0.01). Water quality impairments from FIB were observed across all sites, while treatment locations with livestock presence were found to have significantly elevated staphylococci and E. coli levels following the conservation practice implementation during the winter period. The results of this study showed minimal improvements to TN transport, and in some cases declines in water quality evidenced by increases in FIB, one year after conservation practice implementation. The implementation of conservation practices did not improve the overall water quality to reference levels in the short-term, despite anticipated long-term benefits.

Performance of Common Bean Cultivated in Succession to Cover Crops

Purpose: The present research aims to evaluate the biomass production and nutrient uptake by different cover crops, as well as to verify the effects of straw on bean productivity. Method: The experimental design was completely randomized, consisting of sowing beans on straw four cover crops (Crotalaria ochroleuca, Pigeon pea, Mucuna gray and Lab-lab) + control, with five replications. Results and conclusion: The Pigeon pea species has great potential for dry matter production and ability to absorb and accumulate phosphorus in the leaves in full bloom. The straw of the species Crotalaria ochroleuca, Pigeon pea and Mucuna cinza contributed significantly to the productivity of common bean cultivated in succession, as well as represent an alternative to reduce the dependence on synthetic fertilizers and increase the sustainability of agricultural systems. Implications of the research: The search for maintaining or increasing crop production through the adoption of conservation practices with emphasis on the cultivation of cover crop species is emphasized as an efficient strategy for nutrient cycling, improving soil health and increasing productivity with sustainability assumptions. Originality/value: The results obtained in this study are relevant to the scientific community, contributing to the training of educators and development of students, especially in the area of agricultural and environmental sciences, serving as a scientific basis for the regional technological process.

Persistence and disadoption of sustainable agricultural practices in the Mississippi Delta region

AbstractThe working lands programs in the United States are specifically tailored to support farmers in initiating or enhancing conservation practices. The expectation is that farmers receiving financial assistance will continue implementing these practices even after their initial contracts end, thereby increasing the programs’ cost‐effectiveness and promoting natural resources conservation. However, little is known about the likelihood of persistence and disadoption of conservation practices once the initial cost‐share contracts expire. Using the first‐order Markov chain framework on state‐level conservation practices acreage data from the Mississippi Delta region (2005–2022), this study provides quantitative estimates of changing (dis)adoption patterns of four conservation practices: cover crops (CCs), conservation tillage (CT), nutrient and irrigation management (NIM), and conservation crop rotation (CCR). The findings reveal a higher probability of persistence of NIM practices. In contrast, acres devoted to CCs and CT tend to transition into other alternative practices, indicating a greater likelihood of disadoption. Importantly, the likelihood of acres that initially adopt conservation practices with funding shifting to a condition of no conservation activity is minimal. The transition probability estimates facilitate the prediction of future adoption rates of conservation practices and aid funding agencies in prioritizing their conservation efforts.

Simulation of Long-Term Water Erosion in Rainfed Croplands of Eastern Washington

Highlights Water erosion in the inland Pacific Northwest was modeled with WEPP for the past (1940–1982) and present (1983–2020). Water erosion decreased from past to present in the study watersheds. Major factors are increased adoption of conservation practices and decrease in large precipitation events. Abstract. Water erosion is an ongoing problem in eastern Washington due to its hilly terrain, highly erodible silt loam soils, rain on thawing soil, and the prevalence of conventional tillage. The region is characterized by a Mediterranean-type climate with warm, dry summers and cool, wet winters. Three distinct precipitation zones, with annual totals low (<380 mm), intermediate (380–460 mm), and high (>460 mm), dictate the area’s crop rotations. A unique 43-year (1940–1982) dataset of winter erosion measured on multiple agricultural fields in Whitman County, eastern Washington, by Verle Kaiser, a USDA Soil Conservation Service agronomist, showed annual erosion rates averaging 53.8 Mg ha-1, far exceeding the current Natural Resources Conservation Service tolerable limit of 11 Mg ha-1 yr–1 for the soils in the area. Kaiser’s field data allowed us to compare the historical field-measured erosion rates with those simulated by the WEPP (Water Erosion Prediction Project) model. Anthropogenic factors, such as tillage and crop rotation, change with time. Conservation tillage, including reduced- and no-till, has been increasingly adopted in eastern Washington since the mid-1980s. The specific objectives of this study were to (1) apply the WEPP model to simulate soil erosion in eastern Washington and evaluate the interactive effects of climate and management, in addition to topography and soil, on water erosion in the study area, and (2) compare the simulation results with Kaiser’s historical field dataset and elucidate the long-term soil erosion trend. The WEPPcloud interface was used to delineate a watershed within each precipitation zone of the study area. Climate inputs were divided into two periods: the past (1939–1982) and the present (1983–2020). Erosion has noticeably decreased from the past to the present, with WEPP simulated annual erosion averaging 13.5, 34.5, and 52.6 Mg ha-1 for the past, and 9.5, 14.1, and 15.5 Mg ha-1 for the present, in the selected watersheds in the low-, intermediate-, and high-precipitation zones, respectively. The decreasing trend was primarily due to the increased adoption of conservation tillage and crop rotation, as well as a decrease in the number of high-intensity precipitation events in the present climate. Keywords: Inland Pacific Northwest, Soil erosion by water, Temporal trend, WEPP.

Effect of sociodemographic factors on the adoption of environmental conservation practices in Kimao dam catchment, Baringo County, Kenya

Demographic and land size owned by households often impact the adoption of environmental conservation approaches in wetlands. Kimao dam is at risk of sedimentation, considering the steep topology and reduced vegetation cover. Contemporary attempts by stakeholders to restore water catchments are insufficient due to the low adoption rate of the environmental conservation measures. The study assessed factors that cause the low adoption rate of the environmental conservation practices among households within the Kimao catchment area in Kimalel location, Baringo County. The objectives of the study were to: (i) determine the effects of sociodemographic factors (age, gender, household number) on the adoption of environmental conservation practices, and (ii) establish the effects of land size owned by households on the adoption of environmental conservation practices. The ex-post-facto research design was used. A stratified proportional random sample of 225 households was surveyed using a structured questionnaire. The data were analyzed using descriptive and inferential statistics in a Statistical Package for the Social Sciences (IBM SPSS version 26). The results showed that the level of adoption of environmental conservation practices was low (M=9.47, SD=4.7) on a scale of 1 to 22. The level of adoption of environmental conservation practices within the Kimao dam catchment area was found to be affected by age of the household head (β=.294, t=4.59, p=.001) and household number (β=0.147, t=2.22, p=0.027) but not gender (t=-0.648, df=223, p=0.518). The Land size (β=0.162, t-2.45, p=0.015), also affected the level of adoption of environmental conservation practices. Demographic factors act independently or synergistically with other factors to influence policy adoptions in water ecosystem management. Stakeholders need to provide sound scientific and feasible policies to collaboratively manage the Kimao dam. The findings of the study will influence policy development in implementing environmental conservation practices in Baringo County.

Net greenhouse gas balance in U.S. croplands: How can soils be part of the climate solution?

Agricultural soils play a dual role in regulating the Earth's climate by releasing or sequestering carbon dioxide (CO2 ) in soil organic carbon (SOC) and emitting non-CO2 greenhouse gases (GHGs) such as nitrous oxide (N2 O) and methane (CH4 ). To understand how agricultural soils can play a role in climate solutions requires a comprehensive assessment of net soil GHG balance (i.e., sum of SOC-sequestered CO2 and non-CO2 GHG emissions) and the underlying controls. Herein, we used a model-data integration approach to understand and quantify how natural and anthropogenic factors have affected the magnitude and spatiotemporal variations of the net soil GHG balance in U.S. croplands during 1960-2018. Specifically, we used the dynamic land ecosystem model for regional simulations and used field observations of SOC sequestration rates and N2 O and CH4 emissions to calibrate, validate, and corroborate model simulations. Results show that U.S. agricultural soils sequestered Tg CO2 -C year-1 in SOC (at a depth of 3.5 m) during 1960-2018 and emitted Tg N2 O-N year-1 and Tg CH4 -C year-1 , respectively. Based on the GWP100 metric (global warming potential on a 100-year time horizon), the estimated national net GHG emission rate from agricultural soils was Tg CO2 -eq year-1 , with the largest contribution from N2 O emissions. The sequestered SOC offset ~28% of the climate-warming effects resulting from non-CO2 GHG emissions, and this offsetting effect increased over time. Increased nitrogen fertilizer use was the dominant factor contributing to the increase in net GHG emissions during 1960-2018, explaining ~47% of total changes. In contrast, reduced cropland area, the adoption of agricultural conservation practices (e.g., reduced tillage), and rising atmospheric CO2 levels attenuated net GHG emissions from U.S. croplands. Improving management practices to mitigate N2 O emissions represents the biggest opportunity for achieving net-zero emissions in U.S. croplands. Our study highlights the importance of concurrently quantifying SOC-sequestered CO2 and non-CO2 GHG emissions for developing effective agricultural climate change mitigation measures.

Domestic Water Conservation in the Federal Capital Territory of Nigeria: Perceptions and Practices

Many regions in Nigeria currently experience physical or economic water scarcity; a situation that isexpected to worsen because of the nation’s rapid population growth, which has resulted in increased pressure on available freshwater resources. This study, therefore, examines water conservation practices in the Federal Capital Territory (FCT), one of the fastest-growing areas in Nigeria. A questionnaire was administered to 649 respondents, from across the six Area Councils that make up the Territory. The findings revealed that water investments in the FCT have not yielded 100% public water supply coverage for residents. About half of the respondents (48.7%) reduced their water use by minimizing the water used for washing, and a slightly higher proportion (53.5%) minimized water used for bathing. While rain harvesting was the most widespread conservation practice, with 65.3% of the respondents adopting it, the least practised conservation method is wastewater reuse, where only about 41% of the respondents adopted it. Although themajority of the respondents were literates, education did not impact their conservation practice. The age and gender of respondents played no significant role in the adoption of conservation practices. More public awareness and water education are needed to promote greater domestic water conservation among residents.

Soil microbial properties are improved by the adoption of soil management and conservation practices in no-tillage system

ABSTRACT No-tillage system (NTS) plays a prominent role in conservation agriculture, however, its benefits can be further improved by adopting complementary soil management and conservation practices, such as using autumnal cover crops, contour seeding, and terraces. This study aimed to evaluate how soil biological activity responds to soil management and conservation systems. The treatments consisted of three macroplots with an area of 11.000 m 2 each, as follows: a) Non-Terraced catchment (NTC), cultivated in NTS similar to most farmers of the region, in which the agricultural operations are carried out in the direction of the slope and without terraces used; b) Best Management Practices (BMPs) were adopted in NTS with additional autumnal cultivation of cover crops, and also the direction of machine traffic was transverse to the slope direction; and c) Terraced catchment (TC), cultivated in NTS was associated to mechanical practices to erosion control, using wide base terrace on level. Soil microbial properties sampled in the 0.00-0.10 m layer were evaluated during 2019, 2020, and 2021, all shortly after the summer crop harvest. Natural inoculum potential of arbuscular mycorrhizal fungi (AMF), respirometry, metabolic coefficient, acid phosphatase activity, and organic carbon and nitrogen in the microbial biomass were assessed. Averages of each microbiological properties were compared through the confidence intervals (p<0.05). The results showed a greater potential for AMF inoculum in BMPs and TC systems. The NTC showed the highest values of respirometry and metabolic quotient, releasing 31.7 and 27.3 % more CO 2 compared to BMPs and TC, respectively. The BMPs and TC were able to retain 13.8 and 16.5 % more carbon in the microbial biomass and 8.0 and 8.8 % more nitrogen in the biomass than NTC, respectively. Adopting soil management and conservation practices such as autumn cover crops, level seeding, and wide base terrace on level improved the soil microbial properties, with an increase in AMF inoculum potential, higher levels of acid phosphatase activity, and increment of carbon and nitrogen in microbial biomass.

Effects of Land Use on Soil Physical-Hydric Attributes in Two Watersheds in the Southern Amazon, Brazil

Changes in land use can cause degradation of soil physical quality with negative effects on the environment and agricultural production. The effects of different land uses on soil physical-hydric attributes were studied in the Renato River and Caiabi River watersheds in the southern Brazilian Amazon. Three conditions of land use were evaluated: native forest, crops, and pasture in the headwater, middle, and mouth of each watershed. Particle size, particle density, bulk density, total porosity, macroporosity, microporosity, water contents at field capacity and permanent wilting point, and available water capacity in soil were evaluated in three soil layers down to 0.4 m. Data collected were subjected to the Kruskal–Wallis nonparametric test and Pearson’s correlations. Multivariate analyses were also performed using the principal component method. In the Renato watershed, in comparison with native forest, conventional management of pasture and crops caused soil physical degradation, increasing soil density in the surface layer and reducing macroporosity and total porosity. In the Caiabi watershed, converting native forest areas into pasture and crops altered water quality, influencing the water dynamics in the soil, by reducing soil water conductivity. Soil attributes varied by watershed, with texture variations between the headwater and mouth, indicating that changes in soil properties result from both management and the granulometric composition of the soil in different regions of the same watershed. Adoption of crop and pasture conservation practices can improve soil physical attributes in regions bordering agricultural areas in the southern Amazon.

Scrutinizing the impact of policy instruments on adoption of agricultural conservation practices using Bayesian expert models

AbstractPolicy instruments—such as regulation, financial incentives, and agricultural extension—are commonly applied by governments to promote sustainable agricultural practices and tackle ecosystem degradation. Despite substantial investment, little data are available to gauge the impact of evolving policy mixes. We constructed a Bayesian network model to explore relationships between policy instruments, contextual factors, and adoption. Applying a series of scenarios, we present examples of how different instruments influence adoption and how their effectiveness is shaped by contextual factors. Scenarios highlight that the effect of policy instruments is often modest, and constrained by diverse practice and population characteristics. These findings allow us to reflect on the role of policy instruments, and the conditions necessary to support practice change. For example, our findings raise questions about the role of financial benefits versus financial capacity, and highlight the potential importance of concepts such as mental bandwidth in shaping both motivation and capacity to adopt.

Adoption of Energy Conservation Practices and their Effects on the Performance of Kenyan Lodges and Camps

Purpose: The objective of this study was to assess energy conservation practices implemented by lodges and camps in Kenya and to determine their effect on performance of Kenyan lodges and camps. 
 Methodology: The study adopted a descriptive correlation research design where data was collected from 294 lodge and camp managers in Kenya using self-administered questionnaires. Sample selection was through multistage sampling technique consisting of stratification, proportionate and simple random sampling. The data collected was analysed using descriptive statistics and linear regression analysis in SPSS. 
 Findings: Lodges and camps in Kenya mainly implemented energy conservation practices related to daylighting (M = 4.06, SD =.88) and use of renewable sources of energy (M = 4.02, SD =.87). Further results indicate that energy conservation practices (F [1, 292] = 124.76, p < .001, R2 = .30) significantly effected performance of Kenyan lodges and camps (β = .55, t = 11.17, p < .01). the findings imply that energy conservation practices accounts for 30% of the variation in performance of Kenyan lodges and camps.
 Recommendations: The current study makes theoretical and empirical contributions to eco-friendly practices and the performance of lodging facilities by providing insights into implementation of energy conservation practices, which seems to be lacking in the Kenyan context. As a result, the study recommends that lodging facilities should focus on implementing energy conservation practices, such as use of renewable sources of energy and installation of energy efficient systems in order to achieve positive performance ratings by stakeholders in the industry.

Transforming the Corn Belt: A recipe for collaborative, farmer-driven research and diffusion of innovation

Practical Farmers of Iowa is a unique and longstanding farmer-to-farmer network with a history of driving the use of sustainable practices like cover cropping and low-chemical-input farming in the heart of the US Corn Belt. PFI was at the center of the launch of participatory, on-farm agricultural research in the 1980s, and has grown to a network of over 6,000 farmers, researchers, advocates, and professionals using farmer-driven research and knowledge sharing to change deeply embedded norms of industrial farming in the region. Through in-depth interviews with 26 current and former member farmers, we explore the role of PFI in the adoption of conservation practices, identify its “recipe” of success—the combination of the most important elements of the network according to its member farmers, and discuss issues of how the network should navigate current and future challenges. Farmers told us that PFI generates and shares information, provides a supportive community, acts as a long-distance coffee shop for alternative-minded farmers, and serves as a catalyst for change in the region. The most important aspects of PFI that farmers said supported them in adopting conservation practices were its diverse membership, autonomous functioning, culture of openness, and non-ideological nature. Moving forward, the network faces questions regarding 1) whether to place its focus on corn and soybean farmers or spread its efforts across a diversity of types of farmers and 2) how to build trust and communication between farmers as they become more geographically distant due to increasing farm consolidation. An understanding of how the network functions can enable a deeper understanding of the role of peer-to-peer networks in driving transformative change in agricultural practices and how they can be shaped to create the most impact for farmers.
