The purpose of this paper is to investigate the impact of access to credit and safety nets on fertilizer adoption in rural Ethiopia.

A panel data set collected in 2005 and 2007 on 278 households and over 5,700 plots from the Southern Highlands of Ethiopia is examined. The authors developed a theoretical model relating input use and credit contract under third-party credit collateral agreement. The estimation is based on instrumental variables regressions to account for the endogeneity of credit access, and safety nets in fertilizer demand equation.

Despite increasing trends in fertilizer and improved varieties adoption since mid-2003, only 22 percent of the plots in the sample is actually received fertilizer. Households with more assets measured by livestock wealth are more likely to adopt fertilizer but less likely to participate in the local credit market as they have better savings that could be used to buy fertilizer/improved seeds without credit contract. This suggests poorer farmers heavily depend on credit than wealthier. Participation in safety nets programs did not contribute for increased use of fertilizer suggesting that the program either competes with agricultural labor or the low wage income was not enough to pay for farm inputs.

The findings show that with a heavier reliance on credit by poorer farmers it appears that much might be gained by targeting policies toward increasing credit access to this group.

Studies that utilize repeated plot- and household-level observations are limited. To the knowledge, this is the first study showing the relationship between credit accesses, public work program and fertilizer adoption over time in rural Ethiopia.

Fertilizer overuse is regarded as one of the main contributors to agricultural pollution and environmental problems in China. The purpose of this paper is to evaluate technical efficiency (TE) and fertilizer overuse index (FOI) with respect to China’s arable agricultural production and examine regional variations in terms of fertilizer overuse.

The maximum likelihood random effects–time varying inefficiency effects model was applied to estimate TE, fertilizer use efficiency (FUE) and FOI.

Over the study period (2011–2015), TE steadily increased for each individual province. Overall, mean annual TE was 0.811, implying that, on average, Chinese provinces could increase output by 18.9 per cent given unchanged levels of inputs and technology. Mean annual FOI ranged from 0.008 to 3.139, with a mean of 0.685, suggesting that there is fertilizer overuse in almost all provinces, and that large regional variation exists. Coastal provinces were found to have the highest TE scores, while the central region showed the highest degree of fertilizer overuse.

The results indicate that fertilizer use has had a significant positive impact on production in the China’s arable agricultural sector. High TE was not necessarily associated with low FUE.

Constraints associated with public agricultural extension services imply that farmers increasingly rely on input providers for agricultural innovations and knowledge. Yet such providers are typically commercial profit-making agents and may have an incentive to suggest relatively costly inputs and/or high rates. The purpose of this paper is to look into the case of Bangladesh and the role of fertilizer traders in terms of farmers’ decisions on which fertilizer to apply and at what rate. Using primary data, the authors examine farmers’ chemical fertilizer use and the associated rice production efficiency, based on different information sources (fertilizer traders, government extension agents or own/peer experience).

Using primary data, the present study estimates an ordered probit model and production functions separately based on whether or not a farmer relied on information from fertilizer traders or own experience and government extension agents, and examines the efficiency score of each type of farmer.

The findings demonstrate that the resource-poor farmers rely more on traders’ suggestions for fertilizer application than public extension – but the actual fertilizer information source has no significant effect on the production efficiency of the rice farmers. This study, therefore, does not find exploitative behavior of fertilizer traders. Thus, this study concludes that small rural traders in Bangladesh are working as agricultural extension agents and provide necessary fertilizer application information to resource-poor farmers.

This is a case study based on Bangladesh – an emerging economy in South Asia. The findings of the study may not be generalized for other countries.

To the authors’ knowledge, this is the first study that confirms the role of agricultural input sellers as the extension agent in developing countries.

The purpose of this paper is to examine some factors that influence the intensity of fertilizer use in Malawi.

The study uses Engle-Granger, Engle-Yoo three steps and autoregressive distributed lags (ARDLs) approaches to examine the long-run and the short-run dynamics among the variables using annual data from 1961 to 2006.

The econometric results indicate that all the variables exert significance influence on the quantity of fertilizer demanded excluding population growth, while the results of the short-run model indicate that the responsiveness of fertilizer demand to all the variables is significant.

Although, this study has provided some helpful results in understanding the major factors responsible for low fertilizer consumption in the study but some time series data on important factors are lacking.

The work is different from already existing literature in Malawi. The authors included subsidy and real gross domestic product to account for the effect of macroeconomic shocks and policies, which has not been accounted for by other related empirical studies. Moreover, this study used ARDLs techniques that can overcome the problem of insufficiently long time series data which is a significant contribution to the existing literature.

The purpose of this paper is to understand the critical factors associated with growing fertilizer usage culminating in contamination of soil/water in agriculturally intensive regions of Uttar Pradesh, India. The agriculture sector is seen as one of the major contributors in ensuring food security, however adoption of sustainable agriculture to protect water resources from contamination due to fertilizers and pesticides is becoming pressing to achieve long term environmental security.

A two staged study aimed at monitoring the soil quality status followed by stakeholder survey has been attempted. Attitude-behavior framework based on the theory of reasoned action has been tried to explain the fertilizer use behavior in the study. The results are analyzed through Analysis of variance.

Soil monitoring data showed nitrate and total nitrogen loadings beyond the permissible limit in the identified regions. A questionnaire aimed at determining farmer’s attitude toward fertilizer usage showed a significant influence of factors like net farm income, overall farm yield, extension services, farmer characteristics on one hand and risks associated with changing farming practices, costs of substitutes available, market-based instruments like subsidies and loans on the other. Divergent responses were observed with respect to farmer’s perceived risks from adopting to organic substitutes, linkages of fertilizer application with environmental degradation and the level of adoption of sustainable agricultural practices.

The study can be scaled up to study the inter-regional differences by benchmarking regional responses. It would be interesting to extend the work to find solutions from the farmers as alternative fertility management strategies. The items used in questionnaire are self-made; hence there is still a possibility of enhancing the robustness of scale by applying advanced statistical techniques.

Results of the study indicate excessive nitrogen loadings in farm soils which is an indicator of potential future nitrate contaminated zones or vulnerable zones emerging in agricultural intensive regions. Findings reinforce the role of education, knowledge transfer and awareness for long-term agricultural sustainability. The paper highlights the urgency for reorientation of the support system by the government and policymakers.

The paper attempts to understand the linkage between the agricultural productivity and the environmental implications followed by the reasons culminating in the agri-environmental imbalance. On-site monitoring study followed by assessment of reasons culminating in this scenario has not been attempted earlier and this paper contributes to understanding at dual level. This paper emphasizes on the insights of stakeholder which is instrumental in ensuring agricultural sustainability or otherwise. It takes the position that the farmer’s farm management behavior is strongly influenced by factors like food security and income, keeping environmental quality at second place. It also identifies the barriers for organic farming and other alternative systems as well as explores the economic, social, and philosophical aspects of sustainable agriculture.

The objective of this paper is to examine chemical fertilizer use efficiency at the household level and provide an assessment of the causes of efficiency variation.

A stochastic frontier production function approach is employed to estimate fertilizer use efficiency at the household level.

It is estimated that on average about two‐thirds of the chemical fertilizers utilized are excessive in China. This has serious consequences as the excessive chemicals like nitrogen and phosphate either remain in the soil or flow into rivers and underground water systems or evaporate into the atmosphere.

This study is probably first of its kind in the field and is based on the latest household survey data.

In writing a paper to honour Professor Clem Tisdell, it is apt to focus attention on the environmental and human costs of commercial agricultural production, especially the Green Revolution technology in South Asia during the last few decades. This is an area where Professor Tisdell has done much research, amongst the multitude of other research interests he has pursued in his very illustrious career. Modern commercial agricultural practices involving chemical inputs such as fertilizers and pesticides have been associated with huge increases in food production never witnessed before and, in the case of cereal production (especially wheat) under Green Revolution technology, recorded spectacular growth. As statistics show, production and productivity have increased. However, the high chemical usage of fertilizers and pesticides to bring about these spectacular increases in food production is not without its problems. A visible parallel correlation between higher productivity, high chemical input use and environmental degradation and human health effects is evident in many countries where commercial agriculture is widespread. This paper discusses the environmental and health effects/costs arising from the high use of chemical inputs to increase production and productivity in South Asia, with a field study carried out in Sri Lanka to show the health costs arising from direct exposure to pesticides during pesticide handling and spraying on farms by small‐scale farmers.

The purpose of this paper is to investigate factors affecting farmers’ perceptions and knowledge of soil testing benefits and fertilizers use in Northern Haiti.

Data were collected from 452 farmers within 17 localities in Northern Haiti. The findings reveal that farmers currently have little or no knowledge of soil testing benefits and but know better about fertilizer use. The soil testing benefits and knowledge on fertilizers use were collected using Likert scale. Analyses were done using structural equations model and choice model.

Factors such as farm size, participation in project, rice, banana and cocoa growers, affect farmers’ perceptions and knowledge of soil testing benefits. Factors affecting willingness to pay include group membership, type of crops grown, whether farmer’ land is on the slope, his farm size and whether he participates in the US Agency for International Development (USAID) project. Knowledge on fertilizer use is influenced by rice and banana growers, fertilizer use, participation in soil testing program and AVANSE/USAID. The effects of both latent variables are found to be positive but non-significant.

As policy implication; farmers need training module to be better informed on soil testing benefits.

Soil testing is a novel agricultural input that is being popularized in developing countries. For sustainability of the laboratory to be installed, this study is needed to fill the gap in research on farmers’ behaviors toward and demand of soil testing in Northern Haiti.

The purpose of this paper is to examine the effect of adopting certified food production on chemical fertilizer and pesticide use in China.

The authors estimate fixed effect models to track the changes in agrochemical consumption at household level over time and evaluate the effect of certified food production, using an unbalanced panel data set covering 4,830 households in six provinces over the period 2005–2013.

On average, the authors do not find significant effects of certified food production on either chemical fertilizer or pesticide consumption among Chinese farmers. The effects are heterogeneous across villages, but the heterogeneous effects show no clear pattern that is consistent with different types of certification. The findings are robust to the use of alternative panel structure and certification indicators. The lack of knowledge about certification among farmers, the price premium and differences in regulation enforcement across regions may explain why the authors do not find negative effects on agrochemical use.

This study suggests that careful inspections and strong enforcement of certified food production is needed to ensure that the environmental goals of certified food production can be achieved and the reputation of certification in China can be improved. The inspection of certification producers and the enforcement of current regulations should be stricter for the further healthy development of certified food production in China.

This study is the first attempt to systematically evaluate the impact of food certification on the use of agrochemicals in Chinese agriculture.

China's Government in 2015 announced its goal of stabilizing the use of fertilizers and pesticide by the year 2020. However, implementation of effective policies is not straightforward, while one may even argue that the policy goal is by far not ambitious enough. Hence, it is useful to look at experiences of other countries that have gone through a similar process. In this paper, the authors explicitly consider the case of European Union's (EU’s) policies aimed at greening agriculture. The choice for the EU is motivated by the fact that the EU is about 35 years ahead of China in implementing a policy agenda to counter the problems China is facing now.

In this paper, the authors focus on agricultural inputs, in particular fertilizer and pesticides, as well as land use and their impact on food safety, air and water quality, soil degradation, greenhouse gas (GHG) emissions and biodiversity. Policies related to those issues are discussed for both, China and the EU. Given that implementation and monitoring are critical for the success of policies, the authors also discuss how policies are implemented and monitored under different governance and institutional conditions.

From the EU experiences, positive and negative, three central lessons are drawn: (1) China should strive for cross compliance but in two steps. In the first step, arrangements for on-farm monitoring must be made, coupled with a pilot program of cross-compliance conditions for large farms in selected counties; in the second step, cross-compliance requirements must be introduced for all farmers, with additional funds for rural development in vulnerable areas. (2) Strong stakeholder commitment should be sought in the formulation as well as implementation of greening policies. (3) Monitoring of greening results should be harmonized and standardized across the country, with a limited number of indicators.

This paper contributes to the policy discussion by comparing the agricultural greening measures in the EU (which was some 35 years ago in the same situation as China now) with the measures taken in China so far.
