“…On the other hand, in developing countries, as in the case of Tunisia, these types of works are very limited. Some work that is based on modeling, such as technical-economic optimization in agricultural model for improving the management of plant protection practices (Mghirbi et al, 2016) or others that are based on environmental indicators of sustainability at the farm level using the IDEA method (Sustainability Indicators Farms) (M'hamdi, 2017).…”

The excessive use of pesticides has multiple adverse effects on the environment and human health. For a long time this problem was focused on the technical, agronomic, medicinal and pest management's aspects, while the problem is a behavioral problem and the socioeconomic aspect plays an important role. In order to study the Farmers' risk perceptions of pesticides used in agriculture greenhouses in central-eastern Tunisia (Monastir Governorate), an ordered probit model was tested for 110 farms for greenhouse agriculture. The results showed the significance and positivity of the relationship between independent variables such as extension, use of protective equipment, experience, membership of the public irrigation perimeter, agricultural income, and the variable depending on Farmers' risk perceptions of pesticides used. On the other hand, absence of the relationship between the level of education and the perception that it seems contradictory, but it can be justified by the age of the farmers who is high. The overall significance of the ordered probit model with a perceived acceptable level of perception can be improved by taking into account the heterogeneity of the farmers in this region in terms of age, education level, membership in a public or private irrigation perimeter and the possibility of access to extension. Developing awareness-raising methods are based on demonstrative and simple techniques accompanied by optimal monitoring and control can reduce the rate of excessive use of pesticides and guarantee greenhouse agriculture sustainable in the central eastern region of Tunisia.

“…Therefore, it is important to be aware of the classical, simple, synthetic and adaptive assessment tools of plant protection practices and optimisation of the production systems (Mghirbi et al, 2015;Mghirbi et al, 2017). Among these tools, the Danish indicator was first developed in the 1980s in Denmark, to meet the growing use of pesticides of lower weight and which were not reported in the Danish statistics on quantities (Pingault, 2007).…”

Vegetable crops are acutely sensitive to pest attacks, disease proliferation, and weed development. To control these pests, farmers resort excessively to various chemical plant protection products. Therefore, this study aims to measure the intensity of pesticide use and estimate the phytosanitary pressure according to the phytosanitary practises of market gardeners in the region of Biskra, in the south-east of Algeria. A questionnaire survey was conducted among 96 randomly selected market gardeners in Biskra during two farming campaigns in 2016/2017 and 2017/2018. Results show that out of 70 different active substances, eighteen are mostly applied to seven inventoried vegetable species. Insecticides and fungicides are the most widespread. The average values of the calculated treatment frequency index range from 0.80 to 30.45. The phytosanitary pressure index is particularly dangerous for tomatoes, eggplants, and chilli peppers, with values ranging from 4.03 to 4.29 and 8.25, respectively. In conclusion, the surveyed areas were found to be experiencing considerable phytosanitary pressure, which would harm the environment and human health.

Authors in (Mghirbi et al 2017) propose a decision tool for management of plant protection in agriculture in order to reduce the risk of pesticide toxicity. Adequate pesticide application technologies can improve efficiency of its use and protect public health and the environment.…”

This paper describes a problem of optimal agricultural land treatment using aviation. The studied problem consists of determining the optimal routes for a given set of aircraft used for chemical treatment of arable agricultural land divided into parcels. This NP (nondeterministic polynomial time) problem is represented on a graph and a mixed integer mathematical programming model of the problem is formulated. This mathematical model is a specific variant of the multi-depot vehicle routing problem where a min-cost plan for the transportation of a homogeneous product (chemicals used for land treatment) from different supply locations (airfields) to different demand locations (agricultural parcels) should be generated. Some specifics of the agricultural land chemical treatment are described in the paper and the following specific conditions are taken into consideration: each parcel is treated only by one way of treatment and one aircraft; for each aircraft its chemical and fuel reservoir capacities are sufficient to serve its route. The complexity of the problem and the impossibility to obtain exact solutions for larger dimensions of the problem led to the formulation of a special heuristics which is presented in this paper. Numerical experiments are successfully conducted for larger problem dimensions and results are presented.
