Perceptions and practices of farmers towards the salinity problem: the case of Harran Plain, Turkey
The Harran region, located in the South-eastern part of Turkey, is facing an increasing salinity problem due to excessive and inefficient irrigation practices. In this paper, we survey 619 cotton producers in the region and analyse their perceptions and practices towards soil salinity. The survey results indicate that formal education and training are the central factors that determine the ...

Hedonic analysis of farmland prices: the case of Aragon
A hedonic approach is used to study farmland prices in Aragon (Spain). Data over 450 transactions in 33 shires, in 2001 and 2002 are analysed. The marginal values for irrigated vs. non-irrigated land, the productive orientation and the differentiation of production through a Designation of Origin (D.O.) are used as explanatory variables. Socio-economic variables are also included. A Box-Cox ...

Economic analysis of the reuse of water reclamation in the irrigation of vineyards
The objective of the present work is to determine the economic viability of the System for the Reclamation and Reuse of Wastewater (SRRWW) in the village of Colera in Girona, Spain. The methodology applied covers the identification, quantification and economic evaluation of different impacts, private and external, and allows the most beneficial options to be selected. Reusing the reclaimed water ...

Zimbabwe`s New Farmers Fail to Deliver
HARARE, Zimbabwe, (ENS) - Six years after President Robert Mugabe sanctioned violent invasions of Zimbabwe's commercial farmland - mostly but not entirely white owned - by landless peasants, the facts show that the so-called new farmers have failed dramatically to produce crops to feed their countrymen. The poor peasants who led the invasions, at the behest of Mugabe, have since been driven ...

Progressive N limitation of plant response to elevated CO2: a microbiological perspective
Abstract A major uncertainty in predicting long-term ecosystem C balance is whether stimulation of net primary production will be sustained in future atmospheric CO2 scenarios. Immobilization of nutrients (N in particular) in plant biomass and soil organic matter (SOM) provides negative feedbacks to plant growth and may lead to progressive N limitation (PNL) of plant response to CO2 ...

Sustainable limits for golf course development in a tourist destination
This paper focuses on the sustainable limits of golf courses that could develop into a tourist destination. We consider that any future development for golf courses must be economically profitable and always committed to the environment. To this end we analyse the most important conditioning aspects: first, the economic profit, because the golf courses are business and second, two environmental ...

An overview of microfinance and the environmental sustainability of smallholder agriculture
The interest and growth in microfinance have burgeoned during the last two decades with the involvement of both private and public sector agencies. As a result of the interest in this sector, microfinance services have grown rapidly. However, little attention has been given to the environmental impacts of microcredit, or ways to mitigate those impacts. This is of particular concern in a rural ...

Cadmium absorption and accumulation in different parts of kidney beans, radishes and pumpkins
Abstract: This study is done to measure the absorption and distribution of cadmium in different parts of kidney beans, radishes and pumpkins. Three parts of a field was chosen. In one part 65 ppm of cadmium nitrate was added to water and in the other part 130 ppm, the last part was irrigated with normal water. Samples were digested by EPA 3050 method. Cadmium concentration was measured by Unicam ...

Seasonality in neotropical populations of Plutella xylostella (Lepidoptera): resource availability and migration
The present study aimed to verify (1) whether seasonal increases in neotropical populations of Plutella xylostella are directly provoked by regular influxes of migrants, and (2) whether temporal variation in food availability is the ecological process behind such predictable events. Over 3 years, plants that P. xylostella prefers were cultivated and irrigated in order to provide a continuous and ...

An overview of preharvest factors influencing postharvest quality of horticultural products
Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

Participative modelling to help collective decision-making in water allocation and nitrogen pollution: application to the case of the Aveyron-Lere Basin
The aim of this study is to develop simplified tools and methods in collaboration with local stakeholders to facilitate collective decision-making. The project is based on a series of experiments carried out between farmers and environmental officers and researchers (Aquae Project)1 on the Aveyron-Lere catchment area. Within this framework, a model of the catchment area was constructed to examine ...

Assessing the cost, effectiveness and acceptability of best management farming practices: a pluri-disciplinary approach
The AgriBMPWater project has been imagined and built in a pluri-disciplinary approach and framework, with the study of the object 'BMPs' using several disciplines at the same time (hydrology, economy, sociology, geography and agronomy). The knowledge of the object in each discipline is deepened by a fertile multi-field contribution: borders of disciplines have been broken down, allowing ...

Evaluation of the management practice for controlling herbicide runoff from paddy fields using intermittent and spillover-irrigation schemes
Two water management practices, an intermittent irrigation scheme using automatic irrigation system(AI) and a spillover-irrigation scheme (SI), were compared for the fate and transport of commonly used herbicides, mefenacet (MF) and bensulfuron-methyl (BSM) in experimental paddy plots. Maximum mefenacet concentrations in paddy water were 660 and 540 µgL−1 for AI and SI plot, respectively. ...

Food and water insecurity: re-assessing the value of rainfed agriculture
ABSTRACTRainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural ...

Spatio-Temporal Distribution of Freshwater Snail Species in Relation to Migration and Environmental Factors in an Irrigated Area from Morocco
Nine sites were sampled 19 times over 2 years in an irrigation system in Morocco in order to study species abundance in a snail community in relation to environmental parameters (including human activities) and migration (geographic distance) among sites. Each site was made of a sink and the first meters of the downstream canal. The snail community included four species (Bulinus truncatus, ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Pesticide and Pathogen Contamination of Vegetables in Ghana’s Urban Markets
Abstract The objective of the study was to determine and compare the current level of exposure of the Ghanaian urban population to hazardous pesticide and fecal coliform contamination through the consumption of fresh vegetables produced in intensive urban and periurban smallholder agriculture with informal wastewater irrigation. A total of 180 vegetable samples (lettuce, cabbage, and spring ...
