Through this loan, Ester should double her production, and this will translate into increased income. She then intends to save more money in the future so that she can develop her farming.<br /><br />One objective that Juhudi Kilimo aims at fulfilling is increasing the ease of accessing farm inputs and income-generating assets for farmers.

However, Elizabeth works independently for the success of her children.  She perseveres because she wants to provide a better future for them.<br /><br />Elizabeth  has always loved farming. She is a very proud farmer and enjoys milking her dairy cows.  Elizabeth keeps poultry and grows crops, but she has not been making a good profit because of poor farming inputs. <br /><br />Elizabeth will use this loan to buy farm inputs and purchase high-quality seeds and good fertilizer to improve her crop production.  Modern farming requires the use of modern techniques, and, therefore, using high-quality seeds will assure her of a bumper harvest and increased profit levels.<br /><br />Elizabeth  is very visionary.  Her goal for the season is to boost her crop production over the previous year.',\n",

This area is very fertile, with favorable weather patterns that support farming activities. Ester is happily married and the proud mother of lovely children. Together, they live on a small piece of land that she really treasures. Her primary sources of income are eggs and milk.<br /><br />Although this humble and industrious mother makes a profit, she faces the challenge of not being able to produce enough to meet the readily available market. Therefore, she is seeking funds from Kiva lenders to buy farm inputs such as good fertilizer and good-quality seeds. Through this loan, Ester should double her production, and this will translate into increased income. She then intends to save more money in the future so that she can develop her farming.<br /><br />One objective that Juhudi Kilimo aims at fulfilling is increasing the ease of accessing farm inputs and income-generating assets for farmers. Through the intervention of Juhudi Kilimo and Kiva, inputs such as fertilizers and pesticides have become more accessible to its members than buying a bottle of water. Ester is very optimistic and believes this loan will change her life completely.',\n",
