<div style="background: #f1f5fc;padding: 15px;font-weight: 400;color: #212529;font-size: 16px;margin:unset;line-height: 1.5;">
<p>Traditionally, subsistence farmers have utilized a method known as broadcasting to sow seeds. Generally, broadcasting involves manually dispersing seeds throughout the field by throwing handfuls over the soil. In order for farmers to obtain a substantial yield with broadcasting, seeds must be sown at a relatively high density. Since the seeds were dispersed on the soil surface, some seeds could be lost to birds or field run-off during rainstorms (Johansen, Haque, Bell, Thierfelder, & Esdaile, 2012). Alternatively, line sowing involves sowing seeds in uniform rows either manually or with machinery (Food and Agriculture Organization, 2007). This sowing method allows for higher yields due to reduced plant competition for sunlight, water, and nutrients. Additionally, sowing seeds in rows allows for enhanced weed and pest management since farmers can more easily move through the field to removed weeds and monitor crops for pests or disease (Barberi, 2002).</p>

<p>Protection is the main benefit from using gloves. Repetitive motions, such as when pounding grain, can cause irritation to the skin. When collecting firewood the sticks and logs can scratch or cut the skin (Food and Agriculture Organization, 2016). Weeds can be rough and by scratching their hands many times they can become cut and sore (Espasandín-Arias & Goossens, 2014). By lifting and pulling heavy items the top layer of your skin will separate from the next, causing a blister, by wearing gloves they now will prevent blistering because the glove will act as the top layer of skin and prevent the actual skin from separating (Schaffner, 2013). Manure has a lot of bacteria in it which are harmful if they are swallow, so keeping them away from the hands used to eat with is very beneficial (Furlong, et al., 2015). If farmers are working with firewood or in construction the cloth gloves will work better because they are more durable (Food and Agriculture Organization, 2016). The disposable rubber gloves would be the worst to use in this scenario because they are so thin, stick to jobs were the main goals are to keep hands dry and dirt free when using disposable rubber gloves.</p>

<div style="background: #faf6ed;padding: 15px;font-weight: 400;color: #212529;font-size: 16px;margin:unset;line-height: 1.5;">
<p>Moisture blocking is a way gloves can prevent your skin from drying out and from getting too wet and dehydrating farmer's hands. By keeping the moisture from the hands inside the gloves they will prevent the skin from cracking and becoming infected (Schaffner, 2013). As well when working in wet conditions your hands can shrivel and become dehydrated if they are constantly in contact with water.</p>
<p>Pesticides can be absorbed by your skin and become harmful to the body, gloves provide an extra barrier to block them from entering in a farmer's body (Furlong, et al., 2015). Fertilizers such as nitrogen can also be caustic, and these are usually spread through broadcasting by hand. Mud can get under your nails and into cracked or cut skin and can infect a farmer's hands. Gloves will keep the mud out and keep hands clean. Both liquid pesticides and dry fertilizers can irritate skin if they come into contact with it (Kim, et al., 2013). Wearing the proper gloves, rubber ones in this case, can save their hands from becoming itchy (Keeble et al., 1996). Human skin can also absorb the pesticides which are harmful to your body, wearing gloves would prevent the pesticides from ever touching your skin.</p>

<p>Comfortable gloves help farmer's work longer because their hands will not hurt from completing your task. Sizing is very important when finding comfortable gloves (Melco, 2016). Make sure gloves are the proper length and width, as not to restrict movement. There will be less pain from pulling weeds and they will be able to pull more weeds because they would not have to wait a long for the pain to subside between pulling each weed, because there will be no pain if wearing gloves (Food and Agriculture Organization, 2016). If farmer's find they are working hard and their hands start to sweat the gloves should be removed , dry your hands, and put on a new pair. Cloth gloves are more breathable then rubber ones, using them is another way to prevent hands from getting sweaty. The cloth gloves can also be softer and easier to clean, but are more restricting to movement due to their durability and tougher material. Since children will also be farming, smaller glove sizes can be found. Gloves are designed to fit a farmer's hand snugly, so children should not wear adult sized gloves when working. </p>

<h3 style="background: #d0e5f5;padding: 15px;font-weight: 600;color: #000;font-size: 22px;margin:unset;text-align:center;">Constraints To Adoption</h3>
<div style="background: #f1f5fc;padding: 15px;font-weight: 400;color: #212529;font-size: 16px;margin:unset;line-height: 1.5;">
<p>Gloves are very useful to farmers, but there can still be some drawbacks. Possible culturable taboos might vary from location to location. Gloves might seem feminine and not easily adopted by men in the community. Gloves act as a second, tougher skin, but they are not a farmer's skin and can slide around while working. This may feel odd and uncomfortable but farmers can get used to the new feeling over time. Gloves can come in many colours and thicknesses, which may make a farmer's hands look funny or larger. Human skin is very stretchy and flexible, while glove materials tend to be tougher than skin and will reduce movement, but not enough to hinder work. Rubber gloves can stretch well, but make hands sweat, while cloth gloves are breathable but reduce dexterity.</p>
<p>Farmers can find gloves to use and get started from local vendors (European Commission For The Control Of Foot-And-Mouth Disease, 2016). Once you have completed your work for the day you can clean them are reuse them, or dispose of them if they were ripped or torn (Kim, et al., 2013). You can get gloves made of rubber and like materials as well as ones made of durable cloths. The thin rubber gloves tend to be made for a single use only. A trick that the European Commission For The Control Foot-And-Mouth Disease mentions that you can wear two pairs of rubber gloves at the same time for extra protection (European Commission For The Control Of Foot-And-Mouth Disease, 2016).</p>
