“…Moreover, they are less interested to adopt IPM when they observed that a major portion of the farmers are not adopting IPM. The farmers who cultivated other land were less interested to cultivate vegetables using the new system [40]. On the other hand, farmers who had unfavorable perception towards IPM were less likely to practice this which is consistent with what [24] affirmed that farmers adopted organic practices as they thought the practices are environmentally sound.…”

Past studies on the adoption of integrated pest management (IPM), analyzed the significance of non-spatial factors (social, economic, institutional and management factors etc.) in influencing farmers' decision to adopt IPM while the present study analyzed spatial factors in addition to these non-spatial factors to address the questions-i. Do the spatial factors significantly influence the farmers to adopt IPM? If yes, then to what extent they do affect IPM adoption? The data were collected from 331 vegetable farmers of Narsingdi district, Bangladesh, by conducting a household survey. Farmers' nineteen characteristics under five broad groups, namely social, economic, institutional, management and spatial factors were analyzed. The result of the binary logistic regression model revealed that two spatial factors namely the distance of farmers' house from the nearest market and the distance from agriculture office, along with some specific social, economic, institutional and management factors, significantly influenced the farmers' to use IPM. It is also observed from the model that the role of spatial factors was important in influencing IPM adoption. However, with regard to the level of importance, their contribution was less than those of economic and institutional factors but more than those of social and management factors. The influences of these factors in practicing IPM are discussed individually as well as group based. The findings show significance in domestic policy making.

“…In Ghana's capital, Accra, it has been estimated that of the 80 ML of wastewater generated every day, urban vegetable production alone uses up to 11.3 ML (14 %; Lydecker and Drechsel 2010). Wastewater irrigation offers significant benefits (Raschid-Sally and Jayakody 2008), not the least being accessibility and continuity of supply (Keraita et al 2008a, b), and can confer higher economic returns to farmers (Drechsel and Dongus 2010;Owusu et al 2012). Irrigated urban vegetable production plays an important role in Ghana's cities, covering ∼100 ha in Accra (Van Rooijen et al 2010) and producing 60-90 % of the perishable vegetables consumed in Kumasi (Obuobie et al 2006).…”

“…The fecal contamination of these waters is of particular concern when used to irrigate vegetables consumed without cooking, such as exotic salad vegetables and lettuce (Amoah et al 2005;Amponsah Doku 2010). While farmers typically perceive risks to consumers as low (Keraita et al 2008a, b;Owusu et al 2012), evidence of unsafe levels of fecal contamination on produce has been documented (Amoah et al 2007).…”

International audienceUrban agriculture is receiving increasing attention throughout the developing world, but debate rages as to whether it is a blessing or a curse. Some see it as savior for the poor, providing food, and livelihoods, yet to others it is responsible for harboring and vectoring pathogenic diseases and is an archaic practice that has no place along the path toward development. Consequently, the activity receives a mixed reception, and despite much support in many instances, it certainly does not enjoy universal unimpeded progress. Here, we undertake a global tour of urban agriculture throughout the developing world in an attempt to elucidate the various benefits, costs, and hindrances associated with the practice. Through this analysis we identify the need for better understanding of the following six aspects if urban agriculture is to make a meaningful contribution to food security and sustenance of livelihoods in the future: (1) the global and regional extent of urban agriculture; (2) the contribution of urban agriculture to communicable diseases, especially malaria but also diarrheal disease; (3) the role that urban agriculture does and/or could play in abating both malnutrition and obesity; (4) the impacts of urban agriculture on women; (5) appropriate methods of achieving governance and institutional support; and (6) the risks posed by chemical pollutants, particularly as Africa becomes increasingly industrialized. Overlaying these, we suggest that the time is ripe to extend the debate about urban agriculture’s positive and negative environmental impacts—especially in relation to carbon emissions—from primarily a developed world concern to the developing world, particularly since it is the developing world where population growth and consequent resource use is increasing most rapidly

“…In addition, according to the fi ndings, during reclaimed water irrigation the uptake of chemicals to food grown in the soil will be an important exposure route for human risk assessment (Weber et al 2006 ). Policy efforts should be geared toward updating the knowledge, skills and attitudes of producers through frequent training and workshops, so that untreated wastewater irrigation farmers would better appreciate health-related risks of waste water irrigation and how to adopt risk mitigating strategies (Owusu et al 2012 ). However, some works were related to limited regions, particularly in Asia and Africa.…”

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.
