Hi today I’ll be talking about how to prevent
soil contamination through reducing the usage of pesticides in agriculture.
Soil contamination means when chemicals, nutrients or elements of soil
increases more than it should which in turn causes harm to living organisms. My
group mates will be discussing about other solutions in order to reduce soil
contamination which is through the practice of organic farming and integrated
pest management (IPM).today I will be talent about Agroecology which is the
science and the application of ecological concepts, principles and knowledge to
agricultural processes. With the help of agroecology there can be a significant
improvement in the soil health and a reduction in soil degradation which will
improve the production of nutritious food. The benefits
of using agroecology can be discussed with the following three aspects which.
are the environmental aspect, societal aspect and the economic aspect.
First, let’s talk about the environmental
benefits, in Anuradhapura agroecology promotes sustainable management of
resources like soil fertility, improve water sources and bio-diversity.
Agroecology in sri lanka reduces greenhouse gases and also strengthen crops to
climate changes such as droughts, flooding while increasing the crop
productivity in the country. Small-scale farmers in Africa have used
agroecology to more than double crop yields within 3 to 10 years of implementation,
according to the UN special rapporteur on the right to food.
Moving on to the
societal benefits agroecology has allowed to improve the food safety in term of
quantity and regularity in rural area of the country. Among the agro ecological
practices in sri lanka benefits such as increase in the profitability,
comparable yields and pest controls can be seen. In Cuba, it is estimated that
agro-ecological practices are used in 46-72% of peasant farms, generating over
70% of the domestic food production.
lanka is to reduce the excessive cost created because of the harmful chemical
inputs while reducing the harmful impacts of the environment as well as the
peoples health. In east Africa
maize yields have increased from an average of 1 to 3.5 tonnes per hectare
without the use of chemical insecticides and with minimal external inputs,
according to an evaluation by the Oakland Institute.
Here in sri lanka,
agroecology has been main streamed into district plans and provincial
agricultural policies as well as government support is given to agro ecology
through increasing the budget allocations such as market support and subsidies.
Farmers are motivated to use more agro ecological practices by supporting them
with the necessary funds.
increase in the coordination and planning with the help of agencies such as the
FAO and the CGIRA are used in order to promote the use of agro ecology. Since
small scale farmers produce food for 70% of the global population they are
being given subsidies by the government for using agro economical techniques.
The steps that we
need to take would be to create awareness among the people about the issue of
soil contamination and how it can be prevented. Governments should encourage
farmers for using traditional or organic farming techniques in both developed
countries and developing countries as well as impose taxes for pesticide
production in future.
