Adoption of multiple sustainable land management practices and its effects on productivity of smallholder maize farmers in Nigeria

Using a household and plot‐level survey conducted in Ethiopia, this study analyses the difference in farmers' adoption of sustainable land management (SLM) practices between their rainfed and irrigated plots. The paper also investigates the varying influence of different types of irrigation water management systems and associated irrigation technologies on the adoption of SLM practices in irrigated plots. After controlling for heterogeneity among different irrigation water management systems and technologies, we found that access to irrigation play major role in enhancing farmers' motivation to adopt more SLM practices. Furthermore, the combined effect of irrigation water management system and irrigation technology on type and number of SLM practices adopted is quite varied and very significant. The evidence highlights that farmers adopt more SLM practices in their plots with pump irrigation compared with those plots where gravity irrigation is applied because pump irrigation systems enhance complementarities with SLM practices. Finally, the findings underscore that the type of irrigation water management and the irrigation technology applied play an important role in restoring degraded lands and maintaining soil fertility, even when farmers' adoption of irrigation was not explicitly triggered by concerns for soil health.

Soil fertility in mixed crop-livestock farming systems of Punjab, Pakistan: The role of institutional factors and sustainable land management practices

Aims: To examine the income diversification activities and sustainable land management practices among rural cassava-based farmers in Imo State, Nigeria.
 Study Design: Primary data collection.
 Place and Duration of Study: Michael Okpara University of Agriculture, Umudike, Pre-requisite study, Post-Graduation in Agricultural Resource and Environmental Economics, between August 2017 and January 2018.
 Methodology: Data were collected using well-structured questionnaire, administered to rural cassava-based farmers. Multi-stage and purposive sampling techniques were employed, and one hundred and twenty (120) farmers were randomly selected for the study. Data collected were analyzed using descriptive statistics, Sustainable Land Management Index, Probit model and Inverse Herfindahl–Hirschman Diversity Index. The sustainable land management index (SLMI) was constructed from twelve (12) different sustainable land management indicators based on the sustainable practices prevalent in the study area.
 Results: Results showed that cassava-based production was dominated by female farmers (63.33%) with mean age of 46, married (70.00%) with mean household size of 6 persons. The Inverse Herfindahl-Hirschman Diversity (IHHD) results showed that 87.50% of rural cassava-based farmers diversified their income base into other income-generating activities namely, off-farm and/or non-farm activities. The mean naira value for on-farm income was N 130,646.2k, while that of off-farm and non-farm were N 20,554.17k and N 78,333.33k, respectively. Cassava-based farmers diversified mostly into non-farm activities together with their on-farm activities, with a mean annual income (in naira) of N244,333.60k. The probit analysis showed that off-farm and non-farm activities have positive and significant effects on sustainable land management practices. The off-farm and non-farm activities encouraged the rural cassava-based farmers to adapt sustainable land management practices. However, doubling farmer’s engagement to off-farm activities (off-farm2) had a negative effect on sustainable land management, indicating that doubling their engagement to off-farm activities empowers farmers to adapt unsustainable labour-saving practices such over use of agrochemicals (herbicides, inorganic fertilizers and insecticides), due to drudgery and exhaustion as they allocate more of their labour services to another farmer’s farm.
 Conclusion: In order to improve the adoption and adaption of sustainable land management practices, and reduce the drudgery in cassava production as farmers diversify more into off-farm activities, sustainable labour-saving technologies and practices such as conservation tillage and simple tools that reduce labour requirement in cassava production, save time and energy, were recommended. More lands should be allocated to cassava farmers, as farm land diversity will facilitate the adoption and adaption of sustainable land management practices such as fallowing and crop rotation that increase productivity by replacing fallow periods with growing different crops that replenish soil nutrients.

The slow and discontinuous adoption of agricultural technologies is one of the major threats to low agricultural productivity in developing countries. These actions highlight the challenges encountered in the adoption and the continuous use of sustainable land management practices in addition to the choices regarding the type used. The study investigated factors influencing the adoption decisions of smallholder maize farmers and the intensity of adoption of sustainable land management practices. Empirical data were collected from 250 farmers through interviews using a structured questionnaire. The adopter group and non-adopter group were compared using t-test and chi-square statistics, while the double hurdle with the fractional outcome response model was applied to establish the factors responsible for the adoption and the extent of use of sustainable land management practices. The results indicated that socio-economic and institutional characteristics are determining factors responsible for the adoption of sustainable land management practices and the extent of its use. The study recommended that continuous adoption and extensive use can be fostered by encouraging farmers to join a social organisation where related and relevant information on sustainable land management practices is shared through trained agricultural extension officers. Furthermore, regular training and access to credit facilities should be offered.

As an outcome of agricultural activities, land degradation causes detrimental impacts on the environment and soil. It requires sustainable measures to combat the problem that is becoming critical worldwide. Despite many technological improvement programmes in agriculture, especially on land conservation, adoption has remained low in many developing countries. This situation triggered a further investigation into potential factors influencing sustainable land management practices (SLMPs) adoption in Mbulu district, a semiarid area in northern Tanzania so as to determine and suggest appropriate measures that can promote greater adoption. A cross-sectional study was conducted, and data from 120 farmers was collected using semi-structured questionnaires. The adoption index was computed and determined the level of SLMPs adoption to be low. Probit regression analysis examined the factors influencing the adoption of SLMPs. Results show that gender, marital status, education, land size, and the distance to the extension office significantly influenced the adoption of SLMPs. Specifically, being male, widowed, having formal education, owning a larger size of land, and being closer to the extension office significantly increased the likelihood of the adoption. Also, being unmarried and unaware of SLMPs reduced the probability of the adoption. Awareness-raising programmes must be more targeted and effective to reach the intended audience. In addition, promoting sustainable land management practices that support income diversification and livelihood improvement is crucial in the study area. Furthermore, the adoption of sustainable land management practices requires supportive policy and institutional frameworks in the study area. Overall, addressing these factors requires a multi-faceted approach that involves collaboration between various stakeholders, including farmers, communities, the government, civil society organisations, and the private sector. By working together, these stakeholders can create an enabling environment that promotes SLMPs adoption and contributes to more sustainable livelihoods and income diversification in the study area.

Agricultural information plays a vital role in adopting agricultural technology. The study explored if information acquisition is related to the adoption of sustainable land management practices (SLMP) and jointly decided in Mpumalanga Province of South Africa. Primary data were collected through face-to-face interviews, using a proportionate random sampling technique to get 250 smallholder farmers to participate in the survey. A seemingly unrelated bivariate probit (SUBP) model and a recursive bivariate probit (RBP) model were adopted to examine the objective. The statistical estimation of the SUBP showed that there is a relationship, an empirical association between information acquisition and SLMP; while RBP estimation showed that information acquisition was exogenous in the adoption model; thus, the decision to acquire information and adopt SLMP was not jointly decided. Therefore, the study presents the determinants of information acquisition alongside with the adoption of SLPM. The result from the SUBP model, indicated that the years spent in school; agricultural extension service; the number of extension visits and the years of farming, influenced both information acquisition and the adoption of SLMP. The cost attached positively influenced the adoption of SLMP; while gender, marital status and age only influenced the information acquisition.

The scaling of adopted measures on farms is often proposed however, the factors that inform non-adoption of advised measures are typically overlooked. Better understanding of these factors could offer important insights for overcoming these bottlenecks and therefore offer important potential with respect to addressing agri-environmental challenges. We investigated the factors hampering the adoption of sustainable land management practices advised by the main agricultural extension of Ireland. A large qualitative dataset (N = 760) containing farmers’ reasons for rejection of advised practices was analysed to identify bottlenecks for adoption. Our research showed that rejection can be explained by different underlying reasons. While subsidies exist for the implementation of sustainable land management practices, incentives to implement are insufficient and costs remain the main barrier for the adoption of the sustainable land management practices. Additionally, land ownership challenges and the aging farming population hamper the adoption of sustainable land management practices. Next to an analysis of the reasons for rejection of all advised practices, we investigated three often advised sustainable land management practices in-depth: implementation of riparian buffer zones, preventing cattle access to watercourses and implementation of a nutrient management plan. The differences in barriers for adoption between these practices showed the need for nuanced communication in order to enhance uptake. In order to reach water quality targets through enhanced uptake of sustainable land management practice, advice should be framed and tailored to farmer objectives.

The study investigated the adoption of sustainable land management practices (SLMP) for yam production in Osun State, Nigeria. Primary data were collected from 120 yam farmers with the aid of questionnaire through a multistage sampling procedure. The SLMP studied included structural and mechanical erosion control practices (SMECP), agronomic practices (AP), soil management practices (SMP) and cultivation practices (CP). Data were analysed using descriptive statistics and multivariate probit model. Results revealed that contour bund adopted by 25.5% of the farmers was the only SMECP employed in the study area. The major Ap adopted by farmers were mulching (59.2%), multiple cropping (22.9%), cover cropping (34.2%), and crop rotation (38.3%). Application of inorganic fertilizer (62.6%), compost (23.3%), farmyard manure (25%), bush fallowing (21.7%) and shifting cultivation (20.8%) were the most used SMP while minimum tillage (31.7%) was the only CP adopted in the study area. Educational level of farmers, farm size, labour availability, membership of cooperative associations and extension contacts were some of the socio-economic factors influencing the adoption of SLMP in the study area. It is recommended that strategies to improve educational level of the farmers and create awareness about sustainable land management practices should be reinforced in the study area.

Due to the important role that the agricultural sector plays in sustaining growth and reducing poverty in developing countries, the adoption of practices that have the potential to simultaneously improve agricultural productivity while minimizing environmental impacts is essential. This paper examines the determinants of farmers’ perceptions of climate change and subsequent adoption of sustainable land management practices in the Niger basin of Benin. Binary and multivariate probit models are applied in a two‐stage regression procedure to cross‐sectional data collected through a survey of 545 randomly selected farm households in 28 villages. The findings indicate that there are substitutabilities among three pairs of sustainable land management practices being used by the farmers. Climate change perception is positively related to land tenure, experience in farming, number of relatives, tractor use, and membership in farmers’ organizations, and negatively related to household size, remoteness, and plough use. Moreover, the findings reveal that the uptake of land management practices is related to assets, land tenure, education level of the household head, remoteness, social network, non‐irrigated land size, having a farm located near a river/lake/stream, tractor and plough use, being a subsistence farmer or not, and memberships in farmers’ organizations. The adoption of sustainable land management practices could be encouraged through improving access to markets, adequate roads, and technologies, as well as by promoting membership in farmers’ organizations.

The study examined the effect of market access on the adoption of sustainable soil management practices by farmers in the study area. Specifically, the study described the socio-economic characteristics of the farmers; identified the sustainable soil management practices adopted by the farmers; determined factors influencing the choice of sustainable soil management practices used; determined the relationship between market access and the adoption intensity of sustainable soil management practices and identified constraints faced in adopting sustainable soil management practices. Multistage sampling procedure was employed to collect data from one hundred and fifty (150) farmers. Thereafter, data collected were analyzed using descriptive statistics and multivariate probit regression. The findings revealed that the mean age of the respondents was 45 years, with a mean household size of about 6 members. Majority (69.6%) of the respondents had formal education and a mean year of experience of about 18. The study also revealed that all the respondents had access to one form of market or the other for purchase of inputs and sales of their products. In addition, the mean distance covered from farm to home was less than 5 kilometres for most of the respondents while the distance from home to major market and farm to major market was between 5 and 10 kilometres. The most popular sustainable soil management practices adopted by the farmers were the use of chemical fertilizers, crop rotation and intercropping. Furthermore, the multivariate probit regression model showed that age of the respondents, educational level, farm size, household size, farming experience, farm income, awareness of sustainable soil management practices, average distance to the input market, average distance to the output market, average price of product, average price of input for each practice, subsidies on input for each practice, significantly influenced the adoption of sustainable soil management practice by farmers. Also, it was found by the study that inadequate fund is the major constraint faced by the respondents in adopting sustainable soil management practices.

BackgroundSustainable land management is considered as one of the useful approaches to combat the threat of various forms of land degradation in Ethiopia. Despite this, there is scant information regarding households’ decision towards the implementation of sustainable land management practices. This paper, therefore, looks into the determinants for the continued use and choice of the sustainable land management practices by smallholder farmers and its productivity effect in three randomly chosen districts in Tigrai region, Ethiopia. The study uses data from household survey and key informant interviews. The paper employs a binary logit to analyze the determinants for the decision of continued use of sustainable land management practices, and a multivariate probit to analyze the simultaneous adoption decision of sustainable land management practices using cross sectional data collected from 230 randomly selected households. The impact of sustainable land management practices was also evaluated using propensity score matching.ResultsFarming techniques, wealth status, agro-ecological variations, and plot level characteristics were found to be associated with the implementation decision of sustainable land management practices by rural households. Besides, institutional supports and access to basic infrastructures influenced the overall continued use of sustainable land management practices and the preference of households toward these practices. The study also finds that the value of crop production of sustainable land management users was on average 77–100% higher than that of non-users.ConclusionsThe results of the current study confirm that the implementation of various sustainable land management practices are influenced by farming technologies deployed by rural households, agro-ecological variations, plot characteristics, and institutional supports. The findings also affirm that most of the sustainable land management practices are complementary to one another, and implementing two or more sustainable land management practices on a given plot is highly associated with higher value of crop production. Such complementarity highlights that the productivity effect of a given sustainable land management practice is enhanced by the use of the other ones.

Sustainable land management (SLM) practices are important for tackling agricultural land degradation. This study investigates the association between farmers’ time preferences and their adoption of SLM practices (agroforestry, terracing, and land fallow practices) with intertemporal benefits, and further documents the moderating role of land tenure security in this relationship. The analysis in the paper is based on data from a survey of 480 farmers in south-east Nigeria, complemented by semi-structured interviews. Farmers’ time preferences were elicited using both a survey and experiments with hypothetical payouts. Land tenure was conceptualised as a composite concept to suit the legally pluralistic context of the study area. This study found that many of the sampled farmers have high discount rates. The result further shows that farmers’ time preferences are negatively associated with their adoption of agroforestry and land fallow practices. Moreover, the result shows that both legal and de facto tenure security encourage the adoption of SLM practices. Other factors influencing the adoption of SLM practices include gender, household size, education, credit constraints, marital status, risk attitude, farming experience, and farm characteristics (e.g., erosion problems and steepness of slope). Furthermore, this study found that the security-enhancing effect of land tenure security (de facto) can alleviate the negative influence of time preferences on farmers’ adoption of SLM practices. The findings suggest that farmers with higher discount rates, who have secure tenure rights to land, are more likely to adopt SLM practices, compared to similar farmers without tenure security.

Sustainable land management practices (SLMPs) are important for ensuring environmental protection, food security, poverty alleviation, and economic growth in a nation. The study employed a triple hurdle regression model to analyze the drivers influencing farmers’ awareness and adoption and level of adoption of SLMPs. The results show that farm input source, availability of farm inputs, extension frequency, water sources and marital status, are vital for increasing awareness. It is thus, recommended that actions and policies at public and private levels should be aimed at promoting and improving SLMPs.

The drive for the adoption of Sustainable Supply Chain Management practices among pharmaceutical companies is on the rise given the global effort to attain net zero of carbon emissions as well as attaining other targets for the sustainable development goals. The pharmaceutical industry plays vital role in the manufacturing and distribution of medications, and therefore sustainability issues are critical for the survival of the industry. However, the adoption of sustainable practices in the upstream pharmaceutical industry is still low, and there is lack of empirical research in this area, particularly in emerging economies like Ghana. This study aims to fill this gap by examining the level of adoption of sustainable supply chain practices, focusing on the role of the policy framework, the influence of these practices on company performance, and the role of top executives in ensuring sustainability. The study utilizes a mixed method approach and leverages the upper echelon theory to explore the role of managers on sustainable supply chain practices. This dissertation explore the state of the upstream pharmaceutical Sustainable Supply Chain Management practices in Ghana, evaluate the role of the upstream pharmaceutical policy framework of Ghana on supply chain sustainability, identify how upstream pharmaceutical Sustainable Supply Chain Management Practices influence the performance of pharmaceutical companies in Ghana, and to examine the role of top management in ensuring upstream pharmaceutical sustainable supply chain management practices in Ghana. By addressing the above objectives, the study promotes academic debate and provides insights for policy directions in the pharmaceutical industry for sustainable growth and development. The research design includes both explanatory and exploratory approaches, with a concurrent/parallel mixed methods design combining quantitative and qualitative data. Specifically, the concurrent triangulation design mixed method was adopted. The target population was employees of locally owned upstream pharmaceutical companies in the Greater Accra region of Ghana. From a finite population of about 2000, stratified and purposive strategies were used to select 18 participants under the qualitative aspect, while random sampling technique was used to select 334 for the quantitative aspect of the study. Therefore, the total sample size for this study was 352 participants. Data collection involved the use of questionnaire and structured interview guide, and data analysis included structural equation modeling for quantitative data and thematic analysis as well as content analysis for qualitative data. Quantitative results indicated that Sustainable Supply Chain Management practices have a positive significant association with Sustainable Supply Chain Management performance for upstream pharmaceutical companies. Results showed that, there was positive impact of Top Management Commitment on Sustainable Supply Chain Management to performance. Furthermore, there was justification for Top Management Commitment as a moderator on the association between Sustainable Supply Chain Management practices and Sustainable Supply Chain Management performance. The study's findings on sustainable supply chain management practices in the upstream pharmaceutical sector in Ghana have significant theoretical, managerial, and policy implications. The interviews revealed the importance of socially inclusive practices, eco-friendly manufacturing, waste management, supplier involvement, and collaborations are important factors to consider in achieving sustainability goals. Theoretical implications include the recognition of responsible sourcing as a crucial component of sustainable supply chain management and the importance of socially responsible human resource management strategies. Managerially, the adoption of green manufacturing practices, waste management, and supplier engagement are highlighted as strategies for enhancing sustainability. Policy implications emphasize the need for supportive policies and regulations that promote responsible sourcing, green manufacturing, waste management, and supplier engagement in the upstream of pharmaceutical industry. The study contributes to the literature by providing empirical evidence of the positive association between sustainable supply chain management and organizational performance. The role of top management in ensuring the adoption and implementation of sustainable supply chain management practices is crucial, with implications for leadership, resource allocation, collaboration, and stakeholder engagement. Policy-wise, support for sustainable supply chain management practices and capacity-building initiatives are crucial for the adopting and implementations of these practices within the pharmaceutical industry. Overall, the study provides insights for theory, practice, and policy to enhance sustainability in the pharmaceutical supply chain.
