CHAPTER 1 - INTRODUCTION 1.1. Backgrounds Poverty reduction, access to education, clean water, sanitary, health care, etc. are the top concerned among 17 Sustainable Development Goals - SDGs) which formerly was Millennium Development Goals (MGDs). They are the important issues and attract the attention of every country, especially the developing countries like Vietnam. During the past decades, Vietnam has obtained remarkable achievements in the socio-economic development and poverty reduction. Statistics show that the poverty rate has declined from 37.4 percent in 1998 to 5.8% in 2016 (Demombynes & Vu, 2015; GSO, 2016). The report also shows that the poverty rate in 2016 in rural areas (7.5%) is nearly four times higher than that in urban areas (2%) 1 . The statistics indicate that a large number of rural households still live in poverty under poor living standards and suffer from the lack of socio-economic opportunities. Income of the households in rural area is rather low. In particular, a report by GSO (2016) shows that per capita income per month of the rural households is, on average, 2,437 thousand VND. In the rural, per capita income per month of the bottom quintile (the poorest) is 676 thousand VND, the second bottom (the near-poor) 1,246 thousand VND and the top quintile (the richest) 5,669 thousand VND. Therefore, it indicates that income of the poorest is around 8.4 times lower than that of the richest, which is a great gap. Consumption of the rural households is quite low. In particular, a report by GSO (2014) shows that per capita expenditure per month of the rural households is, on average, 1,609 thousand VND. More specific, per capita expenditure per month of the bottom quintile (the poorest) is 834 thousand VND, the second bottom (the near-poor) 1,154 thousand VND and the top quintile (the richest) 2,576 thousand VND, which indicates a big gap between the poorest and the richest in terms of expenditure. Poverty reduction, income improvement and good health, especially in the rural area, are the most concerned issues among the 17 Sustainable Development Goals. In the world and in Vietnam, many programs and activities have been implemented to achieve these goals, for instance, training, agricultural extension, agricultural technology, finance, job creation, etc. Among them, credit is considered as the most important factors in income-generating activities since the rural households, especially the poor, normally face financial constraint. Without accessibility to formal credit support, poor farmers are unable to expand their production and improve their living conditions (Li et al., 2011). As above-mention, a large number of rural households in Vietnam are still living in poverty. The poor have high demand for credit; however, credit market in rural Vietnam normally faces the problem of demand excessing supply. Thenceforth, the poor have difficulty in accessing formal credit due to the lack of collateral. In rural Vietnam, formal credit is mainly provided by the Vietnam Bank for Agriculture and Rural Development and Vietnam Bank for Social Policies (Ho & Duc, 2015), and recently by microfinance institutions. Inability to obtain formal credit has inhibited farmers from improving their living conditions. Therefore, farmers may rely on informal credit sources to support their production and consumption even though they must pay a much higher interest rate, which may push them deeper into ‘vicious debt circle’ with less repayment capacity. The reasons why farmers still accept the high interest rate from informal sources are its collateral-free merit and quick borrowing procedure.
