Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to environmental pollution. Sri Lanka is also vulnerable to climate change impacts such as extreme weather events and sea level rise. [1]
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
In 2021, she advised the government of Sri Lanka to ban inorganic fertilizers and pesticides [20] [21] stating "This decision will definitely help farmers become more prosperous. Use of organic fertilizer will help provide agri products rich with nutrients while retaining the fertility of the land."
It has been found that food contamination from fertilizer is of little concern as plants accumulate little fluoride from the soil; of greater concern is the possibility of fluoride toxicity to livestock that ingest contaminated soils. Also of possible concern are the effects of fluoride on soil microorganisms. [30] Radioactive elements
Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in 2010 [14]). The southwest portion of the island, where the influence of the moisture-bearing southwest monsoon is strongest, is home to the Sri Lanka lowland rain forests. At higher elevations they make the transition to the Sri Lanka montane rain forests.
Organic fertilizers: The use of organic matter as a soil amendment is a key feature of SRI, as it helps to improve soil health and fertility over the long term. Studies have shown that SRI can achieve high yields with minimal or no use of synthetic chemical fertilizers, while reducing greenhouse gas emissions and further improving soil quality .
Indirect effects are those that have consequences that take longer to develop and may also be longer-lasting. The indirect effects of irrigation include the following: Waterlogging; Soil salination; Ecological damage; Socioeconomic impacts; The indirect effects of waterlogging and soil salination occur directly on the
Other effects include erosion and changes in soil fertility and the length of growing seasons. Also, bacteria like Salmonella and fungi that produce mycotoxins grow faster as the climate warms. Their growth has negative effects on food safety, food loss and prices. [5]
