Although the Integrated Farming Systems (IFS) are promoted to address these issues, their adoption among local farmers has been slow. The adoption is contextual affected by local conditions and factors. To understand the role of IFS in land degradation control and plant diversity enhancement, the objective of this study was to examine the determinants of farmers’ adoption of IFS practices and investigate the role of IFS in land degradation control and plant diversity enhancement on farmlands. Combining socioeconomic survey, econometrics, and ecological assessment techniques, the data representing different types of land degradation and sub-plot level plant diversity were collected using both farmer interviews and field measurements for two groups farmers, those who have adopted some sort of IFS, and other who have not. When compared with non-IFS as base category, the results indicated that education and income positively influenced IFS adoption with a marginal effect of 0.035 and 0.001, respectively, contrasting with the negative impact of landholding size with a marginal effect of -0.081. IFS adoption led to reduced land degradation of various forms as perceived by the farmers, particularly reduced soil acidification with marginal effect of 2.52, soil erosion (2.071), and enhanced plant diversity as shown by the indices, Shannon-Weiner – 1.94, Inverse Simpson – 6.14, species richness – 10.65 for IFS plots compared to 1.03, 2.28, 5.06, respectively for the non-IFS plots. The findings offer valuable insights for agricultural extension authorities and local farmers, emphasizing the benefits of IFS practices. The study also underscores not only the environment gains of IFS practices but also holds the potential for long-term economic and ecological benefits.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 3","pages":"Article 100086"},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949911924000169/pdfft?md5=44342f7cc2aa4ee58e9514aabf298f99&pid=1-s2.0-S2949911924000169-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140631728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the use of mineral fertilizers is critical for achieving higher crop yield and residue return. However, it is crucial to consider the simultaneous use of carbon (C)-rich organic materials alongside mineral fertilizers to support soil health and enhance fertilizer use efficiency. It is proposed that increasing mineral fertilizer use without a concurrent increase in C-rich organic materials may not enhance soil organic carbon (SOC) and soil health in the long term. When the labile pool of nutrients is increased through mineral fertilizer, it can reduce microbial C use efficiency, thereby hindering the formation and stabilization of SOC. This reduction in efficiency can cause a more significant proportion of the returned plant residues to be lost as CO₂ through microbial respiration rather than being incorporated into the SOC pool. However, this effect can be mitigated by the concurrent application of large amounts of organic amendments, such as compost, manure or biochar, which provide a balanced supply of nutrients and C substrates to support microbial activity and enhance SOC formation.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 3","pages":"Article 100096"},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949911924000261/pdfft?md5=d15dee06357e97215443a537fed1978c&pid=1-s2.0-S2949911924000261-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140540809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, it is imperative to understand the perception of rice seed growers towards climate change and identify the major adaptation strategies against climate change along with their significant determinants. In this light, our study used data from 223 rice seed growers in the Chitwan district of Nepal using purposive sampling followed by simple random sampling from Bharatpur Metropolitan City and Madi Municipality. Descriptive statistics were used to illustrate perception and adaptation strategies. The growers were categorized as adopters or non-adopters of strategies using the adoption index. Probit regression was used to determine the significant determinants of the adoption of strategies. The findings revealed that 71% of growers perceived climate change: increased temperature and decreased frequency of rainfall. Varietal selection, green manuring, planting time, improved water management and nutrient management were the major adaptation strategies adopted in the study area. From the regression analysis, years of formal education, experience, contact with extension agents and training were found to be significant determinants of the adoption of strategies. The farmers of Madi were found to be more likely to adopt the adaptation strategies. It is therefore recommended that the local and provincial-level governments explore the institutional service provision system and socio-economic characteristics while considering the location for better farm-level adoption of strategies. The study is useful for policymakers to deliberately target formal education, extension services and training for increased adoption of adaptation strategies in the face of climate change. The identified adaptation strategies and their significant determinants are applicable for the rice seed farming system in similar agro-ecological regions globally.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 3","pages":"Article 100095"},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S294991192400025X/pdfft?md5=a44e7bfc899b037f80094f49d0c6ed61&pid=1-s2.0-S294991192400025X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140348030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, six tillage i) conventional (CT), ii) conventional with bed (CTB), iii) reduced (RT), iv) reduced with bed (RTB), v) zero (ZT), and vi) zero with bed (ZTB) were practiced to evaluate the energy consumption, productivity of wheat-maize and their economic returns. The results showed that CT, RTB, RT, ZTB, and ZT reduced 21% and 13%, 81% and 93%, 36% and 56%, 169% and 263%, and 81% and 152% energy consumption than CTB in wheat and maize, respectively. Considering mean productivity, CT and CTB increased by almost wheat (953.43 ​kg ​ha⁻¹) and maize (466.66 ​kg ​ha⁻¹) yields. However, ZT, and RT had higher EP (energy productivity, 32%) and EUE (energy use efficiency, 30%) in wheat, 14% EP and 10% EUE as compared to CTB in maize. The lower EP and EUE in maize were mainly due to higher inputs/energy consumption in comparison to wheat. The input cost of CT, and CTB was higher in wheat than in other tillage practices, but the wheat yield was statistically similar in CT, CTB, RT, and RTB in both years. The RT had a higher benefit-cost ratio (BCR) in wheat (1.52) and maize (0.74) than intensive CT practice (1.44 (wheat), 0.61 (maize)). In wheat, EUE and EP were significantly higher under RT and ZT treatments, however, both were significantly reduced under bed plantation, contrarily no specific trends were observed in maize. In conclusion, RT could be used for wheat cultivation that consumed lower energy inputs and produced higher EUE, EP, and statistically equal grain yield as compared to CT.

A combination of principal component analysis (PCA) and hierarchical clustering (HC) was used to develop a generalized and domain-specific farm typology in the study areas using farm household survey data collected from 503 respondents. A generalized farm typology was constructed considering all the dataset variables whereas the domain-specific farm typology was developed once all the data variables had been categorized into three groups: variables that describe i) the resource endowment, ii) technologies used, and iii) food and nutrition characteristics of the farm. The farm types identified from the domain-specific farm typologies were merged to develop comprehensive, representative, and meaningful farm types. In both districts, the results of the generalized farm typology are more generic, and are not able to fully capture the diversity of farmers’ resource endowment and food and nutrition security status. Compared to the generalized farm typology, the domain-specific farm typology is more useful for targeting tailored agricultural development interventions. The merged typology results show that a combination of medium resource endowment with medium income, medium technology, and low food and nutrition security farm type (34%) is the dominant farm type in the study areas followed by a farm type combining low resource endowment with low income, high technology and marginal food and nutrition secure (21%). The findings of this study provide several insights into targeting and scaling domain-specific agricultural development interventions that can be applicable for sustainable intensification of mixed farming systems. For example, growing multiple crops in crop rotations and as intercrops; implementing conservation tillage, and introducing improved seed varieties, and livestock breeds offer possible pathways for sustainable agricultural intensification for medium resource endowment, medium technology, and low food and nutrition security farm types.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 3","pages":"Article 100088"},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949911924000182/pdfft?md5=bc6a8ca5eb6def8e8179a2c282f9a911&pid=1-s2.0-S2949911924000182-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140096313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its crucial role, the region faces substantial environmental challenges like soil erosion and land degradation, necessitating the adoption of sustainable land management practices. The aim of this study was to investigate the determinants of the adoption of Soil and Water Conservation Practices (SWCPs) among smallholder farmers in central Kenya. Primary data was collected from three administrative wards of Tharaka Nithi County (TNC) using 150 semi-structured household (HH) questionnaires, Key Informant Interviews (KII), and field observations. STATA and Microsoft Office Excel software were used to analyse the HH survey data, using descriptive statistics, inferential statistics, and the binary logistic regression model. Qualitative data from the KII was analysed through synthesized text summaries. The results show that 65.33 % of the respondents adopted SWCPs on their farms, while 34.67 % did not at the time of our study. The study findings further revealed that farm size (β ​= ​0.641; <em>p</em> ​&lt; ​0.05), and Agro-ecological zone (AEZ) (β ​= ​1.341; <em>p</em> ​&lt; ​0.05) positively influenced the adoption of SWCPs. On the other hand, distance from homestead to farm (β ​= ​−0.003; <em>p</em> ​&lt; ​0.05), and age (β ​= ​−0.039; <em>p</em> ​≤ ​0.05) negatively influenced the adoption of SWCPs by the farmers. Challenges in SWCPs implementation included inadequate capital (76.53 %), high labor costs (62.24 %), lack of technical knowledge (34.69 %), lack of infrastructure (17.35 %), and insecure land tenure (1.02 %). These study findings hold the potential to guide the TNC government in formulating tailored strategies that can foster the adoption and sustainable implementation of SWCPs among smallholder farmers. If properly implemented, the strategies will bolster agricultural productivity, mitigate soil erosion, and enhance the region's overall environmental and economic well-being.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 2","pages":"Article 100081"},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S294991192400011X/pdfft?md5=209d7f2c5db64831d5eccf41a90b423d&pid=1-s2.0-S294991192400011X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140052283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While earlier monsoon rice harvesting by introducing short duration varieties created opportunities for cultivating low water demanding non-rice crops in the dry season, such crops failed in many instances because of heavy rainfall and waterlogging. To address such issue, we have analysed dry season (Nov–Apr) rainfall patterns of six meteorological stations of coastal Bangladesh for studying the feasibility of growing irrigated rice and non-rice crops that can be harvested by April. Very heavy rainfall (&gt;20 ​mm) occurred in 18–23% of the studied years and heavy rainfall (&gt;10 ​mm) in 42–43% of cases creating the risk of water stagnation and damage to non-rice crops. The return intervals between occurrences of heavy rainfall and very heavy rainfall in November to December were 1.3–1.4 years and 1.5–2.5 years, respectively. These rainfall events generally delay establishment of non-rice crops. Similarly, in March and April, the return periods for heavy and very heavy rainfall were 1.3–1.5 years and 1.6–2.1 years, respectively. These rainfall events had a detrimental impact on non-rice crops, especially during their ripening stages. Such rainfall events during field experiments at the study locations were found in three years out of four cropping seasons that reduced sunflower and maize yields by 50–64% and sweet gourd and watermelon yields by 55–84% compared to their absence. The probability of high yield of non-rice crops was &lt;25% and the yield variability was very high (40–75%) compared to general rice yield variability (5–6%). Risk factor analysis also revealed that dry season rice is less risky compared to other non-rice crops. To enhance risk management, intensification of cropping systems can be achieved by promoting cultivation of dry season irrigated rice where there is sufficient stored water for irrigation and encouraging farmers to grow pre-monsoon rice.</p></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"2 2","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949911924000145/pdfft?md5=32cffe5af1213c25e8e888bad8801897&pid=1-s2.0-S2949911924000145-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139935636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
