Impacts of natural resource management technologies on agricultural yield and household income: The system of rice intensification in Timor Leste

Natural resource management (NRM) technologies, such as the system of rice intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of NRM technologies for farmers are often debated. Impacts seem to be context-specific, which are especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research. We analyze the impacts of SRI adoption on rice yield and household income among smallholder farmers in Timor Leste. Heterogeneity is accounted for in an endogenous switching regression framework. Comparing mean yield and income levels, we find no significant differences between SRI adopters and non-adopters. This is due to negative selection bias; SRI seems to be adopted more on plots and by farmers with less than average yields. Controlling for this bias reveals significant yield and income gains. Poor and non-poor households benefit from SRI adoption; small farms benefit more than larger farms. The results also suggest that in the context of Timor Leste SRI may not be beneficial when compared to conventional rice grown under favorable conditions. Some implications for future research are discussed.     

Land conservation and tenure security in Kenya: Boserup's hypothesis revisited

Land conservation technologies used by farmers are known to play an important role in improving farm incomes and household welfare in the long run. For this reason substantial investments have been made in research to improve agricultural technologies in various parts of the world, from the development of new crop varieties to new practices of land management. This paper explores the impact of land rights among other factors on adoption of soil and water conservation practices. The study further tests for Boserup's hypothesis (correlation between population density, land conservation and property rights) using panel survey data collected from farming households. The key findings of the paper are that property right regimes and population density affect both the decision to conserve land as well as the type of conservation practices used by farmers. The results further suggest a positive correlation between land tenure security and population density, thus supporting Boserup's hypothesis. The findings call for pursuit of both short-term and long-term policy measures that offer incentives for land conservation through government initiatives and participation of local communities.     

Stochastic Dominance Analysis of Soil and Water Conservation in Subsistence Crop Production in the Eastern Ethiopian Highlands: The Case of the Hunde-Lafto Area

The aim of this paper is to analyze whether investment in soil and water conservation results in a higher yield and income and/or mitigate variability in yield and income to subsistence farm households in the Hunde-Lafto area. Net returns from crop production with and without soil and water conservation (SWC) are compared based on stochastic dominance (SD) criteria. A non-parametric first order SD and normalized second order are used for data analysis. Analysis is based on the Soil Conservation Research Program (SCRP) database for the Hunde-Lafto research unit. The results of the analysis suggest that adopting a conservation strategy results in higher grain yield and net return than in not adopting. The normalized second order SD analysis results do not support the hypothesis that conservation strategy is unambiguously better than a noconservation strategy in reducing variability in yield and net return to farmers. However, conservation strategy has shown second order dominance at lower levels of yield and income that often correspond to unfavorable rainfall conditions. This makes it a preferred strategy to cope with the most prevalent risk factor of moisture shortage. Therefore, appropriate policies to help and encourage farmers to adopt SWC structures will contribute to improving the welfare of subsistence farm households in the study area and in other similar settings in the country. Designing and implementing SWC techniques that may result in unambiguous second order SD dominance will further improve the desirability and adoption of conservation measures.     

Building smallholder farmers' capacity to adopt climate-smart agricultural practices in flood prone areas: Lessons from Bangladesh

Currently, there is an increased interest in promoting climate-smart agricultural practices (CSAPs) around the globe, however, application of these practices may vary for different climate risk hotspots. Although, climate field schools (CFS) are conducted with the aim of empowering farmers with knowledge on the various agricultural practices, little attention has been devoted to building the capacity of smallholder farmers to facilitate adoption of appropriate CSAPs. Given the effects of climate change on agriculture, it is fundamental for agricultural sustainability to answer the question that has hardly benefited from empirical analysis in previous land use studies, which is: Do CFS build farmers' capacity to adopt CSA in flood prone areas? Cross-sectional data from 600 rural farm households in south Bangladesh is used and the recursive bivariate probit (RBP) is applied to address this knowledge gap. The results reveal that participation in CFS increases the probability of a farmer's soil salinity consciousness by 25% and eventually improves the probability to adopt climate-smart agricultural practices by 20%. We also analyzed the spillover effects of CFS participation on CSA adoption and found that there is a strong spillover effect which has important implications on the cost effectiveness and sustainability of the program. Overall, the study provides empirical evidence demonstrating that participatory approaches stimulate adoption of appropriate CSAPs by building farmers' capacity in recognizing the existing climate risk hotspots.     

Does women’s participation in agricultural technology adoption decisions affect the adoption of climate‐smart agriculture? Insights from Indo‐Gangetic Plains of India

Increased participation of women in the agricultural technology adoption decision by farm households is one of the key indicators of gender empowerment in the agricultural sector. This study examines whether women’s participation in the household decision to adopt agricultural technology affects the adoption of climate‐smart agriculture (CSA), using data collected from 1,267 farm households from two Indian states of Bihar and Haryana. When we considered the sex of the household head (using a dummy variable for male‐headed vs female‐headed household) as a basis of analyzing the role of gender in the adoption of CSA, we found that women in Haryana had no role in the adoption of CSA. On the contrary, when we considered women’s participation in technology adoption decisions as a basis of gender analysis, we found that women’s participation in technology adoption decisions in Haryana is much higher as compared to Bihar. Consequently, the likelihood to adopt CSA is higher in Haryana than in Bihar. We also found that wealth, training, and access to extension and market positively influenced CSA adoption. Qualitative analysis shows that women farmers prioritize family food security rather than farm income, and therefore, they are more likely to focus on CSA to ensure food security.     

ROLE OF VOLUNTARY PROGRAMS IN AGRICULTURAL NONPOINT POLLUTION POLICY

Voluntary programs' effectiveness in reducing agricultural pollution is under debate in the professional literature, within government regulatory agencies, and among legislators. In general, non-farm business owners bear little or none of the costs of environmental degradation that their business activities cause. However, farmers who reside on the farm may bear some of the costs associated with using chemicals. As a result, voluntary programs encouraging adoption of management practices that simultaneously improve on farm and off-farm environmental quality may not require subsidizing farmers for their full loss in profits. However, farmers likely will not adopt regulatory agencies' recommended management practices that do not positively affect on farm environmental quality unless subsidies exceed full adoption costs .     

Impact of farmer group participation on the adoption of sustainable farming practices—spatial analysis of New Zealand dairy farmers

This paper analyzes the impact of participation in farmer groups on dairy farmers’ adoption of sustainable farming practices in New Zealand. A spatial propensity score matching method is used to consider the spatial dependence and social connections between farmers in the decision-making of farmer group participation and adoption of sustainable farming practices. The results show that farmers’ decisions of farmer group participation are affected by their neighbors’ choices, and participation in farmer groups has a positive effect on farmers’ adoption of sustainable farming practices. The findings indicate the important role of social interactions in farmers’ voluntary uptake of sustainable agricultural practices. Overall, the positive effect of farmer group participation on the adoption of sustainable agricultural practices highlights learning and knowledge spillover among farmers, which emerges as important to the formulation of sustainable farming policy.

Costs or gross benefits? – What mainly drives cross-sectional variance in Internet adoption

In this paper, we propose an empirical model of Internet adoption which takes into account the household’s desire to adopt the Internet. Our research supports three central findings. First, we determine the main factors that explain the cross-sectional variance in gross benefits. Second, we estimate the predicted probabilities that a household does not desire to adopt the Internet and that a household desires to adopt the Internet but does not because its adoption costs are higher than its gross benefits. We show that while the cross-sectional variance in the first predicted probability is high, the cross-sectional variance in the second one is low (except for the age factor). Third, we compute the predicted adoption probability assuming that the adoption costs are homogeneous across households. We show that, for a given dimension (except for the age factor), the adoption rate will be only slightly modified if the adoption costs are homogeneous across households. Our results support the argument that the digital divide is mainly due to differences in gross benefits of adoption.     

Adoption of safer irrigation technologies and cropping patterns: Evidence from Southern Ghana

The new irrigation technologies introduced in sub-Saharan Africa aim at ensuring safer vegetable production when untreated waste water is used as irrigation water. This paper examines the adoption of safer irrigation technologies and crop choices among vegetable farmers, using cross-section data from urban Kumasi in Ghana. The study employed a two-stage conditional maximum likelihood approach to examine the impact of crop choices and farm-level characteristics on the adoption of safer irrigation technologies. The empirical results indicate that apart from household and farm characteristics such as access to extension agents, belonging to a farmer's organization and education, cropping patterns tend to influence adoption of irrigation technologies for safer vegetable production.     

Polycentricity, reciprocity, and farmer adoption of conservation practices under community-based governance

Significant steps have occurred under Australia's ‘regional delivery model’ towards devolving responsibilities for natural resource management (NRM) to community-based regional bodies, particularly in respect of motivating farmers to adopt priority conservation practices. Challenges remain in effectively engaging the large populations covered by these bodies, especially with these bodies expected to assume responsibilities that risk them becoming perceived as extensions of government and favoring particular stakeholders. In this article, I examine whether polycentric systems of collaborative community-based governance can help address these challenges. The examination involves double-censored regression analyses of data from postal surveys of farmers in three regions. The findings suggest that community-based approaches are capable under the regional delivery model of motivating greater voluntary cooperation from farmers than otherwise possible. They highlight the importance of farmers coming to adopt reciprocity strategies in their key institutional relationships under this model. It seems subregional bodies have an advantage over regional bodies in motivating such behavior from farmers because the former are better positioned to engage them sufficiently to turn around norms of free-riding or opposition entrenched by earlier paternalistic approaches to agri-environmental conservation. This indicates the value of a polycentric approach to community-based NRM wherein responsibilities are devolved to the lowest possible governance level consistent with the principle of subsidiarity. The economic dividend from increased voluntary adoption of conservation practices under this approach arises from the reduced transaction, political and other opportunity costs of achieving the same result entirely through coercion or financial inducements.     

河北省农户采用蔬菜农艺节水集成技术意愿影响因素的实证分析——以藁城市为例

依据河北省藁城市种植设施蔬菜农户的调查资料,运用两项Logit模型,对农户采用蔬菜农艺节水集成技术意愿的影响因素进行实证研究。研究表明,蔬菜农艺节水集成技术应该重点向家庭年均总收入高、种植业收入占家庭总收入比重高、劳动力占家庭总人口比重高、户主男性、户主文化程度高的农户示范和推广;应加强引导示范户的示范、带动作用;通过各种途径强化节水宣传教育,使农户增强农业节水意识;政府应制订政策,合理提高农业水费,促进农户节水;进一步加大科研人员传播蔬菜节水技术信息的力度;政府应反思其工作方式,采用多数农民满意的扶持方式;尽量少用村干部、培训会方式宣传蔬菜节水技术信息。     

Rural development in the digital age: Does information and communication technology adoption contribute to credit access and income growth in rural China?

Information and communication technology (ICT) plays an important role in rural livelihoods and household well-being. Therefore, this study examines the impact of ICT adoption on farmers' decisions to access credit and the joint effects of ICT adoption and access to credit on household income using 2016 China Labour-force Dynamics Survey data. Both recursive bivariate probit model and a selectivity-corrected ordinary least square regression model are employed for the analysis. The results show that ICT adoption increases the probability of access to credit by 12.8% in rural China and empowers rural women and farm households in relatively less-developed regions to access credit. ICT adoption and access to credit affect household income differently. ICT adoption significantly increases household income, while access to credit significantly reduces it, primarily because farmers do not use the acquired credit to invest in income-generating farm and off-farm business activities. ICT adoption has the largest positive impact on household income at the highest 90th quantile. Our findings suggest that improving rural ICT infrastructure to enhance farmers' ICT adoption and developing ICT-based financial products to enable households to access sufficient funds can improve rural household welfare.     

Organic certification,agro-ecological practices and return on investment: Evidence from pineapple producers in Ghana

The recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and household welfare. However, limited evidence exists on the impact of organic certification on the adoption of agro-ecological practices. In this study, we use unique farm-level data from pineapple producers in Ghana to examine the impact of organic certification on the use of agro-ecological practices such as organic fertilizers, organic pest and weed control, crop rotation, and soil and water conservation, as well as how using these measures affect farm outcomes such as return on investment. Our empirical results reveal that organic certification increases agro-ecological practice use, although from a very low starting point. Using a generalized propensity score approach, we show that there is a positive, but nonlinear relationship between the intensity of agro-ecological practice use and return on investment.     

Hand pollination,mass spraying,and hybrid seedlings: Do these technologies affect the welfare of smallholder cocoa farmers in Ghana?

Adoption of cocoa production technologies has the potential to improve productivity and welfare of smallholder producers in low-income countries. While studies investigating synergies in agricultural technologies are growing, empirical evidence on the determinants and impacts of adopting multiple cocoa production technologies on smallholder farmers' welfare is scarce. Therefore, this study contributes by analyzing the determinants and effects of adoption of multiple cocoa production technologies on the welfare of smallholder farmers in Ghana. To achieve this, we used the multinomial endogenous switching regression and multivalued inverse probability regression adjustment models to a random sample of 2233 cocoa farmers from Ghana. The results show that various socioeconomic characteristics (e.g., farmer's age and experience), resource constraints (e.g., land ownership and credit access), market-related factors (e.g., distance to the market), and production shocks (e.g., rainfall) influence the adoption of multiple cocoa production technologies. Furthermore, the results reveal that adopting multiple production technologies significantly improves cocoa yields, gross income, per capita consumption expenditure, and reduces household food insecurity. Therefore, policies, such as financial support, need to be aimed at improving and strengthening smallholder cocoa producers' capacity to adopt synergistic conventional and non-conventional cocoa production technologies to maximize smallholder farmers' welfare.     

Technology Adoption in the Presence of Constraints: the Case of Fertilizer Demand in Ethiopia

Using a nationally representative dataset, and information on why farmers did not purchase fertilizer, the authors estimate a double–hurdle fertilizer adoption model for Ethiopia. Access is an overriding constraint in four zones. Credit is shown to be a major supply–side constraint, suggesting that household cash resources are generally insufficient to cover fertilizer purchases. On the demand side, household size, formal education of the farmer, and the value–to–cost ratio have the largest impact on adoption and intensity of fertilizer use. The results underline the importance of increasing the availability of credit, developing labor markets, and reducing the procurement, marketing and distribution costs of fertilizer. The authors conclude that current large–scale transport, health, and education investment programs will positively impact smallholder productivity and household welfare. The price sensitivity of farmers suggests that an urea subsidy could be useful in redressing the nutrient imbalance currently observed in Ethiopia.     

Adoption of climate change mitigation practices by risk-averse farmers in the Ashanti Region,Ghana

Uncertainty and risk-aversion are notably absent in the modeling of farmers' adoption of climate change mitigation practices in developing countries even though most of the agricultural mitigation practices also have effects on yield variability. The objective of this paper is to explore the implications for climate change mitigation projects of modeling farmers as risk neutral while in actuality they behave as risk-averse agents. Results indicate that when risk averse farmers are modeled as risk-neutral agents, the size of the incentives needed to induce participation to a carbon sequestration program is miscalculated with serious implications either for the success for projects that aim at compensating for climate change mitigation services or for the economic efficiency of such projects.     

Modeling farmer participation in agri-environmental nitrate pollution reducing schemes

Why do farmers choose to participate in agri-environmental programmes and how do they choose the amount of land they allocate to such programmes? This paper examines the determinant factors influencing farmers' adoption of the EU-financed agri-environmental Nitrate Reduction Programme (NRP) in Greece and the extent of the programme's adoption, in terms of land allocation. The decision to adopt the NRP is modeled as a two-step procedure. First, farmers decide whether to participate in the agri-environmental programme and second, the extent of participation is determined. We employ Heckman's self-selection bias correction model to derive unbiased estimates. Based on farm level data, we develop the profile of farmers who choose to adopt the agri-environmental programme and the characteristics of their farms. The results of the analysis provide valuable policy insights decomposed into the main factors determining first, the adoption of the agri-environmental programme and second, the extent of adoption. By decomposing the determining factors, policy makers can employ this information to design effective agri-environmental programmes, desirable to farmers and more targeted towards specific environmental and agricultural development goals.     

HOW GREEN IS YOUR CAMPUS? AN ANALYSIS OF THE FACTORS THAT DRIVE UNIVERSITIES TO EMBRACE SUSTAINABILITY

I examine the factors that influence the adoption of sustainable practices by institutions of higher education (IHEs) in the United States. Using data from the Sustainable Endowments Institute, I conduct an ordered probit analysis on 180 IHEs. The results show that size and wealth are significant factors in the adoption of sustainable practices and that stakeholders such as faculty, alumni, and the surrounding community also play an important role. I find no evidence that institutions adopt sustainability to attract students. Also, in contrast to the findings of similar studies on for‐profit entities, there is no evidence that regulatory pressures encourage campus sustainability. I also examine the factors that affect the institutions' decision to sign the Presidents Climate Commitment (PCC), a largely symbolic gesture. The results for the PCC are quite different than those for overall sustainability. Most importantly, neither wealth nor size are significant factors in that decision. (JEL Q2, L3)     

Increasing cooperation among plants,symbionts, and farmers is key to past and future progress in agriculture

The collective welfare of crop plants, their microbial symbionts, farmers, and society can be undermined by tragedies of the commons. A crop could increase resource allocation to grain if each plant invested less in sending roots into soil already explored by neighbors and less in stem growth. But evolutionary fitness depends on which plants capture the most soil resources and light (e.g., by growing taller than their neighbors), not just on the efficiency with which those resources are used. As for symbionts, with several strains infecting each plant, only host-imposed sanctions limit the fitness of strains that divert more resources to their own reproduction, at the expense of activities that benefit their host plant. Similarly, individual farmers do not necessarily benefit from pest- and resource-management practices that benefit farmers collectively or society as a whole. Plant breeders have increased crop yields by reversing past selection for individual fitness and they could breed for crops that would favor more-cooperative microbial symbionts. Better aligning interests among farmers and society may be more difficult.
