One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.


Four main impacts of agriculture on the environment

The degradation of land in one form or the other is a matter of serious concern endangering sustainability of agriculture. Landslides caused by rains and flowing water in hilly areas and deforestation, overgrazing and faulty cultural practices in the forest and other plain areas expose the soil to water and wind erosion.


Remedies

There is need for identification and implementation of better management practices for agriculture. There is also need to create financial incentives to encourage biodiversity conservation, improve agricultural policies, and identify new income opportunities for producers.


Conclusion

While there is unlikely to be a “one-size-fits-all” solution for dealing with environmental concerns in agriculture, as agro-ecological conditions and public preferences differ across countries, policymakers must have at their disposal a deep understanding of, and capacity to measure, the linkages between policies and outcomes in order to evaluate and achieve better environmental outcomes in a cost-effective manner.

How does rotational grazing affect biodiversity?

Through grazing for a limited time period in one area, biodiversity of native plants increases because grasses have time to regrow equally without one species taking over and becoming invasive.


Why is maintaining land important?

Maintaining land for agricultural use can also prevent that land from being developed and urbanized, in areas where native species have difficulty finding original habitat. The United States Department of Agriculture Farm Service Agency (FSA) created seven voluntary land conservation programs for this purpose.


How do plants and trees help the aquifer?

Plants and trees in agricultural systems help to retain and add water to underground aquifers. This process is most effective when the crops being grown are perennials that continue to grow every year and have deep, well-established root systems.


Why do grasslands exist?

Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.
