Why the recent food and water shortages are making the climate crisis even worse. Alternet article by Shiney Varghese, Institute for Agriculture and Trade Policy.
Agricultural practices geared towards growing export-oriented monoculture crops are chemical intensive and have resulted in high levels of pollution in local water systems. In addition, nitrogen used in fertilizers leaches into water courses increasing the indirect nitrous oxide emissions downstream. This model of production has intensified water use, both in terms of the water going into the growing of the commodities themselves, but also in terms of inter-basin water transfers.
Protecting our waters in local watersheds and wetlands and using them judiciously in support of local agricultural systems and livelihood practices, rather than continuing with the current strategy of promoting export-oriented, monoculture, industrial, water-guzzling agricultural systems, is key to reducing the water sector’s direct contributions to climate change. Moreover local practices that conserve and enhance local water availability to ensure resilience of rain-fed agricultural systems are necessary as an adaptation mechanism, to meet climate challenges and to help meet food security goals, two of the biggest challenges for developing countries today.
It is time to reevaluate our agricultural policies that promote water and energy intensive agriculture. We will have to make some major changes in our agriculture systems to address some of the upcoming climate challenges. Doing so will help us cope with extreme changes in the hydrological cycle and resultant food and water crises many communities and nations are sure to face. Effective and sustainable water management in agriculture in support of healthy food systems needs to be part of the climate solution.
