Climate change and vigorous impact on Sri Lankan Agriculture

-



 Literally, climate change is the long-term shift in temperature and weather patterns. These shifts are natural and due to the variation of the solar cycle. Nevertheless, human activities have been the main driver of climate change. Without any doubt, weather and climate are the most important factors of agricultural productivity in any country. According to statistics, the average temperature of the country is increasing annually at a rate of 0.01-0.0360C. farmers are not able to face climate change since the high growing population, poor ways of trade, weak infrastructure, lacking knowledge of new technology, etc. 

Sri Lanka doesn’t get regular rainfall according to the monsoons. Maha season and Yala season are the main two cultivation season of Sri Lanka that is fed by the Northeast Monsoon and southwest monsoon respectively. Whereas dry zone and intermediate zones are the major food-producing zones. Droughts and floods are experienced frequently due to changes in rainfall. Excessive rainfalls wash off fertile soil and lead to siltation and eutrophication of reservoirs. Lack of rainfall leads to an increase the evapotranspiration and dry up waterbodies in dry zone.

Since Sri Lanka is a tropical country, it is important to maintain the proper temperature to plant unless injuries that happen to plants are inevitable. According to the observations, rice plants should not exceed the ambient temperature of 350 C for 60-90 minutes at the flowering stage. High temperatures will dry and wilt the plant because of increasing evapotranspiration in the daytime and increase the incest damage and pathogens to plants. Due to increasement of night-time minimum temperature causes negative impacts to tube crop production, decreasing the sugar translocation and increasing the sour taste of fruits.Increasing sea levels will cause to reduce the land for agriculture and decline in the quality of drinking and irrigation water. At the same time, it will disturb Gyben- Herzberg lens of freshwater underneath Regosal in the coastal area.

The ideal strategy to face climate change is adaption and resilience to it rather than mitigation. For example, by promoting micro irrigation in the forms of drips, sprinklers, and mist sprayers to manage water. Annual crop cultivation in the dry zone should be transformed into perennial fruit crop cultivation. Promoting farm soil and moisture conservation. using tail water recovery pits for tail irrigation. breeding short-term crops and resilient to drought, high temperature, pets, and diseases. Having long-range forecasting mechanisms to assist agricultural planning etc.

Without wasting resources of nature utilize the land for agriculture or any other meaningful use. Adoption of a national land use policy and easy credit schemes to reward conservation activities such as soil and moisture conservation; micro-irrigation; storage and processing and high-quality seeds would help propagate responsible farming practices amongst the agricultural community.

By going through the given article, anyone can get to know about climate change and how it vigorously affects Sri Lankan agriculture. The main idea is, it is important to find out adaptations for climate change since it is happening natural consequence of human activity. It is better to aware farmers and people about climate change and makes them invest in renewable energy resources and keep homes cozy. Forests should be protected, and sustainable goals should be achieved. By disclosing new technology and concept like greenhouses, vertical farming, and organic farming with minimum damage to the natural environment is the most ideal method of adopting and defeating the bad impact of climate change. This article is super understandable since it is written in simple English and the points are sorted out clearly and Insightly. Cleary comes up with the main problem, adverse effects, and solutions for the problem.

Silage preparation and fodder preservation methods.

-
Image
  Silage is a product where any green plant material is kept in a place where it can ferment in the absence of air that contains 40-45% of water. Silage is a green succulent. When the green fodders are plentiful, it is preserved as silage for farm animals. The process of conserving green fodder is called ensilage. Green silage is a palatable and nutritious type with a Dry matter of 25-35%. During this process, the fermentation of sugar forms acids and it breaks down some of the forage proteins into simpler compounds, including ammonia.   Crops: Crops that are rich in soluble sugar is suitable for ensiling. Ex: Maize, natural grass, sogam 3-3.5% of molasses is added. Stage of harvesting: Crops should be harvested between the flowering and milk stages (50%). Silo: Silo is an air tied structure designed to store and preserve high-moisture fodder as silage. When it comes to pit silos, pits are dug 2.4 to 3cm in depth and space is required for 400 kg of fodder. ...

Nanotechnology: A New Frontier in Post-Harvest Management

-
Nanotechnology is the art and science of manipulating matter at the nanoscale, where properties and phenomena differ significantly from those at a larger scale. By working with individual atoms and molecules, scientists and engineers can create materials and devices with extraordinary properties and capabilities. This cutting-edge field is transforming industries, including agriculture, with applications that promise to revolutionize food production and preservation. 1 , 2 . Understanding the Challenges of Post-Harvest Management Post-harvest losses are a significant global issue, leading to economic losses, food wastage, and nutritional deficiencies. Several factors contribute to these losses, including: Perishable nature of produce:  Fruits and vegetables have a limited shelf life. Improper handling and storage:  Damage during harvesting, transportation, and storage accelerates spoilage. Pathogens and pests:  M...

What is Biosystems technology

-
Image
                                   Basically, biology means studying life. This word derives from the Greek word where “bios” is life and “ logos” is study. system is a collection of parts that work together to complete a specific task. Hence you know that biosystem is not a simple thing. Yeah, it is a complex topic where we can talk and learn many aspects. Once you separate the parts of the car into the engine, tyers, body we can say each part as a car but once these parts are integrated, it is a car, and it functions as a car. This is very similar to a system and biosystem also functions like this. Another example is a living cell. Life is marvelous. Animals, plants and fungus are the living things that are visible. Bacteria, virus and other microorganisms are living things that are not visible to our naked eye. There are a few characteristics that are displayed by living things (life). By these....
