ATLAS OF CLIMATE ADAPTATION IN SOUTH ASIAN AGRICULTURE

Given the escalating climate-related threats, it's crucial to pinpoint the spatial and temporal vulnerabilities that could affect agriculture. To counteract these challenges, we require adaptation strategies. In light of this urgency, the Borlaug Institute for South Asia (BISA), with backing from the Bill & Melinda Gates Foundation (BMGF), collaborates with national agricultural research systems across South Asia. Together, they aim to craft the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).

South Asia, being a focal point for climate change impacts, calls for concerted action both within and among nations in the region to enhance the resilience of agriculture and livelihoods against the adverse effects of climate change. This includes addressing the escalating frequency and severity of extreme weather events, escalating temperatures, and shifting precipitation patterns.

Initiated through an inception workshop held from April 25th to 27th, 2023, in New Delhi, India, this project is funded by the Bill and Melinda Gates Foundation (BMGF) and coordinated by the Borlaug Institute for South Asia (BISA). It represents a collaborative endeavor involving BISA, the Indian Council of Agricultural Research, the Bangladesh Agricultural Research Council, the Nepal Agricultural Research Council, and the Sri Lanka Department of Agriculture.

The project's objective is to pinpoint climate change-induced risks and prioritize adaptation strategies at a localized level to facilitate scalable adaptation efforts.

WAGE RATE

 What is Wage Rate?

Pay rate, or wage rate, is the rate of pay per period of work or unit of production. Pay Rate Extended Definition. Pay or wage is the compensation paid to workers for their labor. The rate at which it is offered is called pay rate. Pay rate can be based on time or unit of production.

Wage rates in agriculture can vary widely depending on factors such as location, type of crop or livestock, seasonal demand, government regulations, and the skill level of the workers. Here are some general details about wage rates in agriculture:

• Regional Variances: Wage rates can differ significantly between regions due to factors such as cost of living, availability of labor, and local economic conditions. For example, wages in developed countries with higher living standards tend to be higher compared to wages in developing nations.
• Type of Work: Different tasks within agriculture may command different wage rates. For instance, specialized tasks requiring specific skills or qualifications may pay more than general labor tasks such as harvesting or planting.
• Seasonal Nature: Many agricultural activities are seasonal, leading to fluctuations in demand for labor and wage rates. During peak seasons such as planting or harvesting, wages may rise due to increased demand for workers.
• Government Regulations: Some countries have regulations governing minimum wages for agricultural workers to ensure fair compensation. These regulations can influence wage rates and vary widely between countries.
• Skill Levels: Skilled agricultural workers, such as those with experience in operating machinery, managing livestock, or specialized crop cultivation techniques, may command higher wages compared to unskilled laborers.
• Benefits and Perks: In addition to wages, agricultural workers may receive benefits such as housing, meals, healthcare, or bonuses based on performance or productivity.
• Trends: In recent years, there has been a trend towards mechanization and automation in agriculture, which can impact wage rates by reducing the demand for certain types of manual labor while increasing the need for skilled workers to operate and maintain machinery.

COST BENEFIT ANALYSIS

 Cost Benefit Analysis

Cost-benefit analysis (CBA) is a valuable tool in agriculture for assessing the economic viability of various projects, policies, or interventions. Here are some details about cost-benefit analysis specifically applied to agriculture:

• Project Evaluation: In agriculture, CBA is used to evaluate investment projects such as the adoption of new technologies (e.g., irrigation systems, machinery), infrastructure development (e.g., building storage facilities, roads), or changes in production practices (e.g., switching to organic farming methods).
• Crop Selection: Farmers and policymakers can use CBA to compare the costs and benefits of different crop options. This includes assessing factors such as input costs (seeds, fertilizers, pesticides), expected yields, market prices, and risks (e.g., susceptibility to pests or weather conditions).
• Livestock Management: CBA helps in evaluating investments in livestock production systems, such as housing facilities, feeding regimes, and breeding programs. It considers factors such as feed costs, labor requirements, animal health, and market prices for livestock products.
• Environmental Impact Assessment: Agriculture often has environmental implications, and CBA can be used to assess the costs and benefits of environmental conservation measures or sustainable farming practices. This may include investments in soil conservation, water management, biodiversity enhancement, or carbon sequestration.
• Government Policies and Subsidies: Governments use CBA to evaluate agricultural policies and subsidy programs to determine their economic efficiency and effectiveness in achieving desired objectives such as food security, income support for farmers, or environmental sustainability.
• Risk and Uncertainty: Agriculture is inherently risky due to factors such as weather variability, market fluctuations, and disease outbreaks. CBA helps in incorporating risk and uncertainty by conducting sensitivity analysis or using techniques such as Monte Carlo simulation to assess the robustness of results under different scenarios.
• Social and Distributional Impacts: CBA in agriculture considers not only private costs and benefits but also social and distributional impacts. It evaluates how different stakeholders, including farmers, consumers, and communities, are affected by proposed agricultural projects or policies, and whether there are any equity concerns.
• Long-Term Planning: CBA aids in long-term planning by assessing the economic viability of investments over the project's lifespan. This includes considering factors such as depreciation of assets, changes in input prices, technological advancements, and shifts in market demand.

Cost Benefit Analysis of adaptation options for Rice

 Rice

Paddy cultivation is a significant agricultural activity in Sri Lanka, deeply rooted in the country's culture and history. Paddy cultivation in Sri Lanka dates back over 2,000 years. Ancient Sri Lankans developed advanced irrigation systems, including tanks (reservoirs) and canals, to support rice farming, which is evident from historical sites like Anuradhapura and Polonnaruwa.

Paddy cultivation in Sri Lanka dates back over 2,000 years. Ancient Sri Lankans developed advanced irrigation systems, including tanks (reservoirs) and canals, to support rice farming, which is evident from historical sites like Anuradhapura and Polonnaruwa.

Sri Lanka has two main paddy cultivation seasons:

• Maha Season (October to March): Corresponding to the northeast monsoon, this is the primary cultivation season.
• Yala Season (April to September): Corresponding to the southwest monsoon, this is the secondary cultivation season.

Cultivation Practices

• Land Preparation: Fields are plowed and leveled to ensure even water distribution.
• Sowing: Seeds are either directly sown or transplanted from nurseries.
• Water Management: Efficient irrigation practices are crucial, using both rainwater and controlled irrigation systems.
• Weeding and Pest Control: Manual weeding and the use of herbicides and pesticides help manage weeds and pests.
• Fertilization: Organic and inorganic fertilizers are applied to enhance soil fertility.
• Harvesting: Rice is harvested using sickles or modern machinery, depending on the scale of the farm.

Conducting a cost-benefit analysis (CBA) for rice cultivation involves evaluating various adaptation options to determine their economic viability and overall benefits.

1.Adaptive Varieties vs. Conventional Varieties 

In Sri Lankan agriculture, there are several riIn Sri Lanka, various paddy varieties are cultivated to meet the diverse needs of its agricultural landscape. Bg 352, BG 366, Bg 360, BW 367, AT 362,BG 409, BG 359, BW 372, AT 307, LD 368, BG 357 are some main varities of paddy in sri lanka.

In Sri Lanka, several paddy varieties have been developed specifically for their adaptability to diverse environmental conditions, allowing farmers to cultivate rice in various agro-climatic zones across the country. Some notable adaptive paddy varieties in Sri Lanka include:

• AT 362: This variety is known for its versatility, being able to thrive in a range of agro-climatic conditions. It's valued for its good milling quality and is cultivated in both irrigated and rain-fed areas.

• LD 264: LD 264 is prized for its adaptability to the dry zones of Sri Lanka. It has a short duration and high yield potential, making it suitable for areas with limited water availability.

• Bw 352: Bw 352 is another adaptive variety known for its resilience to pests and diseases. It's cultivated in intermediate and dry zones, where it can withstand various environmental stresses.

• AT 303: AT 303 is favored for its adaptability to both irrigated and rain-fed lowland areas. It's known for its good milling quality and resistance to blast disease.

• AT 400: AT 400 is a newer variety developed for its adaptability to changing climate conditions. It's known for its high yield potential and resilience to drought.

These adaptive paddy varieties play a crucial role in Sri Lanka's agriculture, helping farmers mitigate the challenges posed by climate variability and ensuring a stable rice production across different regions of the country.

Farming adaptive varieties brings many benefits compared to traditional farming. These special plants are chosen because they grow better in local conditions, like the weather and soil. Because they're so well-suited to where they're planted, they need fewer things like water and chemicals to grow healthy. This not only saves farmers money but is also better for the environment. With adaptive varieties, farmers can count on more consistent harvests, even if the weather isn't perfect. Plus, these special plants help keep the farm's ecosystem healthy by attracting helpful bugs and other creatures. Because they're unique, adaptive crops can often be sold for more money, helping farmers earn a better living. And as the climate changes, these special plants can help farms stay strong and keep producing food for everyone.

2. Minimum land preparation

Minimum land preparation, also known as conservation tillage or no-till farming, can be an effective adaptation option for rice cultivation. This practice involves reducing the intensity of soil disturbance, which can have several benefits including improved soil health, reduced erosion, and lower labor and machinery costs. Here's a detailed look at conducting a cost-benefit analysis (CBA) for adopting minimum land preparation in rice farming.

Cost Benefit Analysis of adaptation options for Maize

 Maize

Maize farming in Sri Lanka is a big deal for food and money. People grow maize in different parts of the country, from lowlands to uplands. There are many types of maize, each with its own good things like how fast it grows or how much it can produce. Farmers do a lot of things to grow maize well, like getting the land ready, planting the seeds, and keeping the plants healthy.

Maize cultivation in Sri Lanka is practiced in several districts across the country, with varying degrees of intensity. Some of the main districts known for maize cultivation are Badulla, Anuradhapura, Ampara and Monaragala. 

1. Hydensity and normal cultivation

High-density cultivation of maize, as an adaptation option, offers significant potential benefits in terms of yield and resilience to climate variability. However, it also entails higher costs and management complexity. A thorough cost-benefit analysis should be conducted, considering local conditions, market prices, and resource availability, to determine the overall viability and sustainability of high-density maize cultivation.
