Most studies focus on specific commodities or report as part of a singular index, use outdated secondary data, or implement highly localized studies, leading to broad generalisations and a lack of regional comparison. We collected representative primary data with more than 5000 households in 55 communities in Eastern Nepal, West Bengal (India) and Northwest Bangladesh to explore seasonally based diversification experiences and applied novel metrics to understand the nuanced status of farm diversification. While 66 crops were commercially grown across the region, only five crops and three crop families were widely grown (Poaceae, Malvaceae, and Brassicaceae). Non-cereal diversification across the region was limited (1.5 crops per household), though regional differentiation were evident particularly relating to livestock and off-farm activities, highlighting the importance of cross border studies. In terms of farmer's largest commercial plots, 20% of systems contained only rice, and 57% contained only rice/wheat/maize, with substantial regional diversity present. This raises concerns regarding the extent of commercially oriented high value and non-cereal diversification, alongside opportunities for diversification in the under-diversified pre-monsoon and monsoon seasons. Future promotional efforts may need to focus particularly on legumes to ensure the future sustainability and viability of farming systems.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"1 2","pages":"Article 100017"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50203334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate-smart agricultural practices (CSAPs) have been identified as a promising solution to combat this problem. This paper reviews the literature on CSAPs in sub-Saharan Africa (SSA). Specifically, the review describes the existing literature on the adoption of CSAPs in the region, provides a more up-to-date summary of this expanding and important issue and presents an overview of the current evidence of CSAPs as a reliable means for farmers in SSA to address the climate change issues. The existing literature suggests that the rate of adoption of CSAPs in SSA is comparatively low. However, the adoption of CSAPs varies greatly across the region. The studies that constitute this review also provide evidence of the benefits of adopting CSAPs to farmers and the environment, ranging from increased productivity, resilience, and income for farmers, decreased greenhouse gas emissions to improved soil health. The decision to adopt particular CSAPs is influenced by several factors, including personal and social-psychological factors, environmental, physical, and ecological factors, farm and economic factors, as well as institutional, policy, and structural factors. Also, gender-based barriers in agriculture impact the adoption of CSAPs in SSA, placing women at a disadvantage. The review concludes that it is crucial to address the barriers and leverage the drivers to improve the adoption rates of CSAPs in SSA.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"1 2","pages":"Article 100019"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50203977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, a stepwise survey involving all the municipalities of Atacora (9) in Benin and Houet (13) in Burkina Faso was conducted among 400 family farmers. The planned behavior model was then used to analyze their intentions and decisions to adopt these practices through structural equation modeling. Findings show that regardless of the practice, farmers' perceived control influences their intention as well as their adoption decision. Similarly, farmers' intention also had a positive and significant effect on their decision to implement these two practices.

Conservation tillage and N fertilization are promising and widely used to improve water use efficiency; however, the mechanisms underlying still need to be addressed. Field experiments were conducted at the Hexi Corridor of northwestern China from 2019 to 2020, where tillage practices, i.e., conventional tillage (CT) and no-till with plastic film mulching (NTP), and N fertilizer rates (135 ​kg ​N ha⁻¹ [N135], 180 ​kg ​N ha⁻¹ [N180], and 225 ​kg ​N ha⁻¹ [N225]) were applied. The results showed that NTP led to a soil water change (i.e., water consumption from the soil) increased by 101.7% during the concurrent growth period in a specific soil layer at 0–30 ​cm compared to CT. It also lowered the total soil evaporation (22.3%) and improved the total transpiration (13.4%). Consequently, no significant difference in evapotranspiration between the NTP and CT groups was observed. N135 decreased the soil water change by 9.0% and 15.2%, and improved the total soil evaporation by 3.4% and 8.4%, respectively, compared with N180 and N225. Tillage practices and N fertilization had an interactive effect on water productivity. Under CT, the grain yield and water use efficiency based on evapotranspiration (WUE_ET) of N180 were reduced by 9.4% and 7.6%, respectively, compared to those of N225. In contrast, under NTP, no significant difference was found. Structural equation modeling (SEM) analysis showed that the tillage practices improved WUE_ET by reducing soil evaporation and improving transpiration. However, N fertilization improved WUE_ET uniquely by improving transpiration. Consequently, we concluded that no-till combined with 180 ​kg ​N ha⁻¹ could be used as an effective measure to achieve higher water productivity of spring wheat in arid areas.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"1 2","pages":"Article 100021"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50203981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smallholder farmers are the most affected. Therefore, it is imperative to identify technologies that boost resilience to climate change, and restore lands. Push-pull technology is among proposed solutions. This technology controls stem borers, fall armyworm, striga, mycotoxins; improves availability of nitrogen and phosphorus, and stores increased carbon in biomass and soils. Though much has been published about push-pull technology, there is a lean in publications about how this technology can help smallholder farmers to cope with climate change and variability. Here, we present perceptions of adopters of push-pull technology in western Kenya with regard to climate change and land degradation, and discuss reasons it should be adopted widely. We compared push-pull and other maize-based cropping systems in western Kenya, through interviews. Push-pull technology produces 0.3–1.1 ​t more maize ha⁻¹ compared to maize-bean intercrop, and maize monocrop when the season is drier than normal. Additionally, push-pull provides 3.6–9.8 ​t more fodder during drought-stricken seasons. Push-pull technology covers 70% of the soil surface compared to 20% cover found in maize-bean intercrop and maize monocrop. In push-pull farms, 150–280 ​kg nitrogen, 13–24 ​kg phosphorus and 370–470 ​kg potassium can be recycled through biomass and this is five times greater than the potential for maize-bean intercrop and maize monocrop.

This study evaluated weed and yield responses to pre-emergence herbicides (pendimethalin, pretilachlor, butachlor, oxadiazon and no application as the control) under different weed management options during the 2018 and 2019 early wet seasons in farmers’ rice fields. All pre-emergence herbicides reduced weed flora and pendimethalin was most effective in controlling the population of mainly grassy weeds. Pendimethalin significantly reduced weed dry biomass by 36.2% (21.3 ​g ​m⁻²) in 2018 compared with the untreated control. In 2019, weed dry biomass was significantly reduced by 46% (17.9 ​g ​m⁻²) with butachlor compared with the untreated plot. Pendimethalin increased toxicity in rice plants, which decreased SPAD (leaf greenness) by 44.8% and tiller numbers by 39.3% at 7 days after herbicide application (DAPH) compared with butachlor, but plants recovered from pendimethalin toxicity at 14 DAPH. In 2018, oxadiazon herbicide significantly increased grain yield by 61% (4.6 ​t ​ha ⁻¹) compared with the untreated control, but oxadiazon produced similar grain yields as pendimethalin. In 2019, there was no significant effect of pre-emergence herbicides on yield but butachlor produced the highest rice yield (3.2 ​t ​ha⁻¹) followed by pendimethalin (2.8 ​t ​ha⁻¹) and oxadiazon (2.7 ​t ​ha⁻¹). Our study demonstrated that pre-emergent herbicides function differently under varying soil-water conditions in 2018 and 2019, therefore rice growers can use butachlor to control weeds in dryer soil conditions and potentially use pendimethalin to control weeds in good soil moisture conditions. This information is crucial and safe in developing appropriate strategies to manage weeds and enhancing DSR productivity in lowland ecosystems.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"1 2","pages":"Article 100018"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50203773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the extensification of agricultural practices by many smallholders due to limited access to funds, agricultural inputs, or knowledge may result in a more environmental-friendly oil palm production. Here, we assessed the trade-offs between production and soil degradation in two oil palm farming systems established on forested land in the Ngwei region (Cameroon) comparing practices with no (smallholder system, SH) and low (elite system, EL) agricultural inputs (fertilizer, herbicides). Soil characteristics, nutrient deficiencies and oil palm production were determined in forty-two plantations of different age covering one full plantation cycle.
