The content of carbohydrates and organic acids in organically grown vegetables and dried vegetable products
2010
Ozolina, L., Latvia Univ. of Agriculture, Jelgava (Latvia) | Kuka, P., Latvia Univ. of Agriculture, Jelgava (Latvia)
The content of carbohydrates (fructose, glucose, and sucrose) and organic acids (citric acid, succinic acid, malic acid, sorbic acid, and ascorbic acid (vitamin C)) in organically grown vegetables (carrots, parsnips, celeriacs, and red beets) and dried vegetable products were analyzed by the HPLC reverse phase and ion exchange methods. The main carbohydrate detected in fresh vegetables invariably was sucrose (1.29 – 11.17 g 100 gE-1). Fructose and glucose were found in similar ranges (0.09 – 2.47 g 100 gE-1, 0.14 – 3.02 g 100 gE-1 respectively). A similar distribution of carbohydrates was determined in dried products. The highest fructose and glucose contents were found in fresh carrots - 2.47 g 100 gE-1 and 3.02 g 100 gE-1 respectively; but in dried carrot products – 14.53 g 100 gE-1 and 15.43 g 100 gE-1. High amounts of sucrose were found in red beets: 11.17 g 100 gE-1 in fresh samples, and 48.50 g 100 gE-1 in dried products. Malic and citric acids were detected as the main acids of fresh vegetables. Highest citric acid amount was in red beets (266.19 mg 100 gE-1), whereas celeriacs and parsnips had a high malic acid content. The results from this study demonstrated variability and concentration range of carbohydrates and organic acids, wherewith the organoleptic profile of the products. Dried products are considered as a good source of energy.

2015
Drechsel, Pay | Keraita, Bernard N.
Thirsty and hungry cities are posing significant challenges for the urban-rural interface ranging from food security to inter-sectoral water allocation. Not only is the supply of resources to urban centres a growing challenge in low-income countries, but even more is the urban return flow, as investments in waste management and sanitation, ie the ‘ultimate food waste’, are not able to keep pace with population growth. And where polluted water is used in irrigation to feed the cities, food safety is becoming a crucial component of food security. Most affected by resource competition and pollution are the urban and peri-urban farming systems which are often driven by the informal sector. Urban waste is not only a challenge but also offers opportunities. It is in this interface between agriculture and sanitation where the CGIAR operates through its research programme on Water, Land and Ecosystems (WLE), addressing both the challenges and opportunities of urbanisation: by exploring novel perspectives and solutions to respond to changing population dynamics, resource demands, centralised water and nutrient flows, and ecosystem services under pressure.

Revitalized agriculture for balanced growth and resilient livelihoods: Toward a rural development strategy for Mon State
2016
Center for Economic and Social Development | International Food Policy Research Institute | Michigan State University
The purpose of this report is to provide national- and state-level policymakers, private-sector investors, civil society, and donors with an analysis of the rural economy of Mon State and pathways to improved prosperity for its population. The analysis is based on a representative survey of rural households, which make up 73 percent of Mon State’s 2 million residents, and extensive interviews with farmers, traders, processors, local leaders, and government officials. Whereas some parts of the Mon State economy are quite dynamic, such as construction, others are stagnant and far from reaching their full potential. Furthermore, the dynamic sectors are heavily dependent on remittances from migrants to neighboring countries. The current pattern of donor investment is heavily focused on necessary infrastructure and energy investments, but with only very limited support to productive sectors, especially agriculture and fisheries. Major investments in education, both formal and vocational training, are also necessary to support the growth of a modern economy. The analysis in this report identifies options for more balanced growth, leading to a vibrant economy in which returning migrants can invest and find employment.

On March 6, 2022, at the Fifth Session of the Thirteenth National Committee of the Chinese People’s Political Consultative Conference, Chinese President Xi Jinping emphasized that China needs to improve the lives and livelihoods of its people and to ensure an adequate food supply by providing enough meat, vegetables, fruit, and aquatic products for healthy diets. Understanding the changing trends of people’s dietary structure and encouraging people to eat more healthily is central to establishing the “Big Food” concept. The country should actively promote reform of the agricultural supply side in order to achieve a balance between the supply of, and demand for, various types of food and to better meet the increasingly diversified food consumption needs of the people. | Non-PR | IFPRI4; DCA; 3 Building Inclusive and Efficient Markets, Trade Systems, and Food Industry; 2 Promoting Healthy Diets and Nutrition for all | DSGD

The purpose of this report is to provide information and analysis to government, civil society, and donors interested in improving the well-being of the rural population of Mon State. Specifically, the report analyzes the different sources of income for rural households, as well as their socioeconomic characteristics, with a view to identifying potential pathways to improving incomes, especially for poor households, and stimulating inclusive rural growth. The overall picture that emerges is one of an economy heavily dependent on services for local employment and on international migration for income. Like a two-legged stool, such an economy is potentially unstable in the face of external shocks. Diversification of the Mon State economy, including diversification and increased productivity within the agricultural sector, will lessen the relative dependence on external migration remittances and result in more resilient growth in the future
