Technical efficiency of water use and its determinants, study at efficiencies in small-scale irrigation schemes in North-West Province, South Africa
Provedor de dados: 31
Autores: Speelman,   Stijn; D'Haese,   Marijke F.C.; Buysse,   Jeroen; D'Haese,   Luc.
This paper analyses the efficiency with which water is used in small-scale irrigation schemes in North-West Province in South Africa and studies its determinants. In the study area, small-scale irrigation schemes play an important role in rural development, but the increasing pressure on water resources and the approaching introduction of water charges raise the concern for more efficient water use. With the Data Envelopment Analysis (DEA) techniques used to compute farm-level technical efficiency measures and sub-vector efficiencies for water use, it was shown that under Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) specification, substantial technical inefficiencies, of 49% and 16% respectively, exist among farmers. The sub-vector...

A FARM LEVEL ANALYSIS OF THE RELATION BETWEEN CAP REFORMS AND LOCAL ENVIRONMENTAL LEGISLATIONS: HOW AND IN WHICH EXTENT FLEMISH DAIRY FARMERS CAN FILL UP EXTRA MILK QUOTA?
Provedor de dados: 31
Autores: Van der Straeten,   Bart; Buysse,   Jeroen; Nolte,   Stephan; Marchand,   Fleur L.; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
The agricultural policies shift gradually from EU-level organised market interventions to local organised environmental policies. This paper explores the growth possibilities of the Flemish dairy sector with the outlook of a quota abolishment as a case study of this policy shift. The dairy quota policy seems very restrictive for the highly profitable Flemish dairy sector, but the environmental restrictions from the manure regulation can limit the growth of the dairy sector as well. The paper uses a spatial multi-agent simulation model applied to a sample of 40.000 farms to estimate price development of emission rights and their possible impact on the growth of the dairy production. The results show that a higher milk production leads to higher prices for...

Sub-vector Efficiency analysis in Chance Constrained Stochastic DEA: An application to irrigation water use in the Krishna river basin, India
Provedor de dados: 31
Autores: Chellattan Veettil,   Prakashan; Ashok,   Arathy; Speelman,   Stijn; Buysse,   Jeroen; Van Huylenbroeck,   Guido.
All deviations from the frontier is inefficiency in deterministic DEA (DDEA); thus making the DDEA unable to accommodate the measurement and specification errors.  But, most of the production relationships are stochastic in nature with some inputs fixed in the short run. This paper addressed the above two issues by formulating a sub-vector efficiency model in a Stochastic DEA (SDEA) framework to analyze the efficiency of sub vector of inputs.  The results illustrate that there is a wide scope for stochastic efficiency analysis.  The overall efficiency in SDEA is higher than DDEA under both Constant and Variable Return to Scale frameworks.  SDEA revealed that some efficient producers are not sub-vector efficient in our case study.  Thus, overall efficiency...

Autores: Frija,   Aymen; Speelman,   Stijn; Chebil,   Ali; Buysse,   Jeroen; Van Huylenbroeck,   Guido.
This article analyzes the efficiency of Water Users Associations (WUA) in the Cap Bon region (Tunisia) and studies its main determinants. The analysis is performed in two stages. First, the efficiency is measured via the nonparametric “Data Envelopment Analysis” (DEA) technique. The DEA models are constructed not only to assess the overall WUA efficiency but also to evaluate the management and engineering sub-vectors efficiencies separately through a mathematical modification in the initial DEA model. In a second stage critical determinants of efficiency are determined using a Tobit model. In this analysis the focus is on technical (characteristics of the irrigation area and network), organizational and administrative variables. Results show that on...

Autores: Alam,   Mohammad Jahangir; McKenzie,   Andrew M.; Buysse,   Jeroen; Begum,   Ismat Ara; Wailes,   Eric J.; Van Huylenbroeck,   Guido.
Spatial price integration among five major Bangladesh rice markets is examined in the presence of threshold effects to account for the impact of transaction costs in the price adjustment process. Hansen and Seo (2002) threshold cointegration tests and threshold vector error correction models confirm the presence of threshold effects. Results highlight the importance of directing policy goals towards reducing transaction cost to engender greater pricing efficiency in Bangladesh rice markets.

Impact of Alternative Implementations of the Agenda 2000 Mid Term Review
Provedor de dados: 31
Autores: Buysse,   Jeroen; Van Huylenbroeck,   Guido.
An agricultural sector model for ex ante policy analysis is developed and applied for the simulation of alternative implementations of the Agenda 2000 Mid Term Review (MTR). The model uses an adapted version of Positive Mathematical Programming allowing simultaneous modelling of individual farms. It applies farm level calibrated quadratic cost functions to a sample of the Farm Accountancy Data Network to account for the large variability among farms. The farm level approach is important for the evaluation of the MTR, because MTR policy instruments rely on differences between farms. Extending the model for coping with the MTR implies three important elements: i) modelling the activation of decoupled direct payment entitlements, ii) simulating the modulation...

An application of Data Envelopment Analysis (DEA) to Evaluate Economic Efficiency of Poultry Farms in Bangladesh
Provedor de dados: 31
Autores: Begum,   Ismat Ara; Buysse,   Jeroen; Alam,   Mohammad Jahangir; Van Huylenbroeck,   Guido.
This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the...

A new methodology for assessing the impact of water-pricing scenarios: case study of small-scale irrigation schemes in South Africa
Provedor de dados: 31
Autores: Speelman,   Stijn; Frija,   Aymen; Farolfi,   Stefano; Buysse,   Jeroen; D'Haese,   Marijke F.C.; D'Haese,   Luc.
Worldwide growing water scarcity has increased the call for economic instruments to stimulate rational water use in agriculture. In addition cost-recovery is now widely accepted as a cornerstone of sustainable water management. As a consequence now in developing countries, where currently agricultural water use is often still heavily subsidized, a tendency exists of introducing water-pricing as a policy to achieve more sustainable water use. The exact impact of water pricing policies on irrigation water use or on the farmers’ production system is however mostly unknown. A new two-stage methodology that allows estimating at the farm level the effects of introducing or raising a water price on the agricultural production process and water demand is...

The paper discusses an ex ante evaluation of the derogation on the Nitrates Directive for Flanders, Belgium, which is a case of intensive but highly productive livestock areas. The aim is to develop an accurate simulation model to detect small differences in manure surpluses caused by changes of manure production and/or utilization. The system of models consists of various modules to fine tune the calculations of manure production, fertilizing behaviour and manure allocation and disposal on and off farm. The results show that derogation may cause the existing manure surpluses to expire, if only nitrogen limits are considered and no transactions costs are taken into account. When also phosphate fertilization limits are considered, the increase in manuring...

Optimisation of policy interventions in environmental quota

Autores: Buysse,   Jeroen; Van der Straeten,   Bart; Nolte,   Stephan; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Van Huylenbroeck,   Guido.
The paper analyses the governance choices in production quota with the Flemish nutrient production rights as a case. A static model of quota trade in the short run shows the inefficiency of discrete non-auctioned trade with fixed transaction costs. This model also shows that an obligation to quota sellers to stop their production stimulates structural change. A dynamic model of trade indicates that the measures taken to prevent speculative behaviour causes inefficiencies and stimulates overuse of quota if the penalties are too low. Finally, the dynamic model indicates that a flat rate reduction on traded quota combined with too low penalties for overuse stimulate the total production.

Autores: Frija,   Aymen; Buysse,   Jeroen; Speelman,   Stijn; Chebil,   Ali; Van Huylenbroeck,   Guido.
The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) in Tunisia. During the last years there has been a lot of discussion in Tunisia about the optimal size of WUAs, which allows more efficient management of the water resources at the local level. In this work we propose to see if the size of the WUA in the governorate of Nabeul (Central-Eastern part of Tunisia) would have to increase or decrease in order to maximize their efficiency. Apart from this qualification we also quantify the scale efficiency and scale elasticity of the WUA using Data Envelopment Analysis (DEA) models. The results show that the output space (volume of water distributed and number of ha managed and irrigated) of the WUA that attain a high level of...

Autores: Mondelaers,   Koen; Kuosmanen,   Timo; Van Passel,   Steven; Buysse,   Jeroen; Lauwers,   Ludwig H.; Van Huylenbroeck,   Guido.
There is a high potential for simultaneously increasing sustainability of the earth system and economic development by removing inefficiencies currently present both at the production input and output side. In this paper a static view on sustainability is employed, by introducing capacity constraints as the boundaries above (or below) which the system cannot maintain its stable state. Currently these capacity constraints are often not respected. In this paper it is shown how the efficiency improvement pathway of an industry and the firms within it can be calculated to come to a sustainable, profit maximizing state, given the existence of these capacity constraints.

Total Factor Productivity and the Efficiency of Rice Farms in Bangladesh: a Farm Level Panel Data Comparison of the Pre- and Post-Market Reform Period
Provedor de dados: 31
Autores: Alam,   Mohammad Jahangir; Begum,   Ismat Ara; Rahman,   Sanzidur; Buysse,   Jeroen; Van Huylenbroeck,   Guido.
The market reform policy in agriculture and the trade liberalization during the early 1990s has led to structural changes in the agricultural sector of Bangladesh. The question of whether market reform policies in Bangladesh facilitated rice production is examined in this paper. This paper uses stochastic frontier production function to measure total factor productivity (TFP), technical change, and technical efficiency change covering the period of pre-market reform (1987) and post-market reform (2000 and 2004). To fulfill the objective, the study used panel data of 73 same farm households from a field survey of 1987–1988, 1999-2000 and 2003-04. It is evident from the study results that over time period (1987-2004), the TFP increased (31.76%) only due to...

The Importance of Water Property Rights: Lessons from South Africa and Tunisia
Provedor de dados: 31
Autores: Speelman,   Stijn; Frija,   Aymen; Buysse,   Jeroen; Van Huylenbroeck,   Guido.
With increasing water scarcity, research on policy options for improved water allocation and governance becomes an urgent priority for many developing and developed countries. Evaluating institutional alternatives is however a challenging task. This article takes a comparative approach and compares case study data from Tunisia and South Africa highlighting the importance of the water rights system for irrigators. Using contingent valuation methods the benefits for water users of changes in water rights systems are quantified. In both countries WTP estimates reveal that from the farmers’ perspective significant improvements can be made to the current water rights systems. This is valuable information for policy makers to guide institutional reforms.

Autores: Alam,   Mohammad Jahangir; Buysse,   Jeroen; Begum,   Ismat Ara; Nolte,   Stephan; Wailes,   Eric J.; Van Huylenbroeck,   Guido.
The paper analyzes the impact of trade liberalization and changes in world prices of agricultural commodities in Bangladesh using single country CGE model. Since the agricultural sector is sensitive to overall employment, household welfare and food security, the analysis focuses on the changes in agricultural production, consumption, household income and welfare. The results show that trade liberalization increases the welfare of all household groups while world market price increases decrease welfare. It means that although trade liberalization generates a welfare increase for households but this is dependent on the relative level of world commodity prices. Our results are based on the analysis of aggregate household groups, so it may be of future...

Autores: Buysse,   Jeroen; Van der Straeten,   Bart; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Marchand,   Fleur L.; Van Huylenbroeck,   Guido.
To explain over- and underuse of available quota, Buysse et al. (2007) have integrated the shadow cost of the quota constraint in a quota flexibility function in a positive mathematical programming model. This method and central hypothesis, formulated and tested for the case of Belgian sugar beet farms, is in current paper extended and confirmed for the cases of Flemish dairy quota and manure emission rights. Despite the different organisation, objectives and implementations of the diverse quota systems, the results are similar. A higher utilisation of quota is significantly driven by the quota rent, but farm characteristics are also important and the effect declines with increasing quota rent. Regardless the quota, the dairy quota flexibility behaviour of...

Price Transmission in the German Sugar Market
Provedor de dados: 31
Autores: Nolte,   Stephan; Natanelov,   Valeri; Buysse,   Jeroen; van Huylenbroeck,   Guido.
The German sugar market is governed by the European Union’s common market organization (CMO). In 2006, the CMO was subject to its first major reform. Among others, the administered price for sugar was reduced by 36%. We use a data set with monthly prices for sugar and sugar containing products to perform a cointegration analysis. Results show that the reduction of the institutional price has led to a reduction of wholesale prices and of retail prices for table sugar. Prices for sugar containing products are barely integrated with the sugar price, though. Some are found to be integrated with the CPI for food and soft drinks. In none of the cases where linear cointegration could not be detected, threshold cointegration could be found.

The paper examines the relationship between the world market and domestic market prices of rice for Bangladesh in the regime of agricultural trade liberalization. The long run price relationship information is an important piece of information for the policy makers in formulating domestic polices and negotiating trade policies at the international level. The monthly data used for this study are taken from different sources, the Food outlook, FAO and Global Information and Early Warning System, FAO and the Bangladesh Bank for the period June 1998 to July 2007. Both Engle-Granger bi-variate and Johansen multivariate cointegration tests were used for the results sensitivity. We sequentially proceed to estimate the standard error correction model.

Autores: Van der Straeten,   Bart; Buysse,   Jeroen; Nolte,   Stephan; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
Within the framework of the nitrate directive, member states have the possibility to apply for derogation, i.e. increasing fertilization standards under certain conditions. Several EU regions have made use of this possibility but all in a different way. In 2009, 6 different derogation policies were worked out. This paper focuses on the differences between the applied policies and makes an assessment of the impact of these differences on the application rate of derogation, the manure surplus and the costs to allocate the manure. Based on the MP-MAS model described by Van der Straeten et al. (2010) the different scenarios are applied on a single case area (Flanders) and the economic effects have been simulated. Results show large differences between the...

Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land) compared to the current historical system (payments based on individual historic entitlements). Impact on production and income of arable, dairy and cattle farms of two different flat rate scenario's, is assessed with a farm-based sector model for Flanders. The model maximizes income at farm level, calibrated to observed farming behavior in 2001-2003. Farm data can be selected by farm type, size and region, simulations could be run for specific sub sectors, size...

Modelling the effects of an abolition of the EU sugar quota on internal prices, production and imports

Autores: Nolte,   Stephan; Buysse,   Jeroen; Van der Straeten,   Bart; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Van Huylenbroeck,   Guido.
We apply a spatial price equilibrium model of the world sugar market to simulate an abolishment of the EU quota system in 2015/16. To overcome the normative nature of the approach, we calibrate the model by attaching a non-linear cost term to each trade flow. This is in some regards similar to positive mathematical programming. We suggest an economic interpretation and an econometric specification of the cost term. Production in the EU increases to almost 16 million tons. Twelve member states increase production, seven reduce it. Preferential imports are significantly reduced. Simulated effects are found to be more pronounced the higher the world market price.

For practical considerations, it is in some case impossible to simulate MAS models at population level. The current paper shows that MAS models applied to samples with heterogeneous costs of interactions between agents have biased results. Heterogeneous costs of interactions in MAS models can come from the spatial dimension in MAS models or from fixed costs per interaction. The paper presents two correction procedures to remove the sampling bias and to increase the reliability of the outcome. The correction procedures can be very promising for future applications of MAS models because it becomes possible to deploy more complex models without bias on more detailed datasets that are only available at sample level, which will be the case for country- or...

ESTIMATING THE EFFECT OF WATER CHARGE INTRODUCTION AT SMALL-SCALE IRRIGATION SCHEMES IN NORTH WEST PROVINCE, SOUTH AFRICA
Provedor de dados: 31
Autores: Speelman,   Stijn; Buysse,   Jeroen; Frija,   Aymen; D'Haese,   Marijke F.C.; D'Haese,   Luc.
In South Africa water law has recently changed, adopting the principle of water as an economic good, thus levying charges on its use. For small-scale irrigators this is an important change, because currently their water use is entirely subsidized. In the coming years, subsidies will gradually decrease and an essential expected benefit of this policy change is that water use efficiency will rise, leading to reduced consumption and possible reallocation of the water saved. The exact impact of the water pricing policy on the irrigation water use or on the farmers' production system is however unclear. This study introduces a new methodology, based on data envelopment analysis, that allows estimating the effects on the agricultural production process and water...

In 2005, 30% of the Flemish farms faced a manure excess, while at aggregated level still 9.7% of the emission rights were unused. This means that, despite the various possibilities, Flemish farmers do not succeed in an effective exchange of manure between farms. In current paper is shown how inorganic fertilizer use influences the use and exchange of organic nitrogen. Because of the mutual interdependency between organic and inorganic nitrogen emission rights (or quota), inorganic nitrogen use limits the emission rights for organic nitrogen. Utilisation of these emission rights are analysed as a trade-offs choice between plant productivity (use of inorganic nitrogen) and manure disposal, as the major abatement alternative of manure production. Farmers...

Market liberalization at the domestic level and at the boarder level has been a dominant feature of market reforms in most developing countries including Bangladesh during the last two decades. A pre-requisite for producers and consumers to benefit from this new and changing market environment is the ability of market to function efficiently at their spatial or through the value chain dimensions which are very often constrained by different factors. The vertical integration of grain markets plays a crucial role in improving the welfare of the producers and the consumers. Therefore, the better the market integration, the lesser the intervention required by the government. There was a widely-held belief about the domestic markets in Bangladesh on possible...
