Contribution of the Dolichos Lablab value chain to farmer's household livelihood assets in Tanzania
(Elsevier Inc., 2022-11-17) Minde, Josephine; Matemu, Athanasia; Venkataramana, Pavithravani
Lablab is a legume with multiple uses as food, feed, and organic fertilizer. However, it is underutilized, and its empirical contribution to farmers' livelihoods is limited. This study examined the Lablab value chain (LVC) relative to smallholder farmers' livelihood assets in Tanzania. Data on Lablab farming, its value chain, and its contribution to the farmers’ livelihood assets were collected from four districts of Tanzania known for Lablab production. The results showed that the LVC mapping comprised systems, actors, and interdependent activities, the key systems being input supply, tillage, intercropping, and marketing. Seed supply was through the recycling of the last harvest (48.8%), while intercropping (56.5%) and hand-hoeing (51.6%) were the primary cultivation systems, with farm gates and/or local markets serving as the marketing locations. The grown seeds were mainly black (62.3%) due to external marketability but were rarely eaten. Although farmers were the major chain actors, traders were highly active in the marketing segment, leaving farmers out of the bargain art protocol. Generally, Lablab production generated almost 90% of the farmers' revenue by multiple linear regression. Based on farmers' five asset categories, natural and human assets contributed 70% and 50% respectively, while there was less contribution from social, financial, and physical assets. The study recommends networking exposure to reliable marketplaces with good prices, improved seed availability, and financial services for Lablab farmers in Tanzania. To sustain the smallholder farmers' five livelihood assets from Lablab, researchers and policymakers must pay attention to the three linkages of the LVC.
Dolichos Lablab-an underutilized crop with future potentials for food and nutrition security: a review.
(Taylor & Francis Online, 2020-06-12) Minde, Josephine; Venkataramana, Pavithravani; Matemu, Athanasia
Achieving the Sustainable Development Goals (SDGs) particularly goal number two in developing countries by 2030 is challenging. The State of Food Security and Nutrition (2019) in the World show prevalence of undernourishment which has practically remained unchanged for the last three years. This calls for sustainable synergies between food and nutrition in addressing the challenge. Exploring the potential of underutilized legumes such as Dolichos Lablab () in improving food and nutrition security is of importance. Lablab is known among nutritious underutilized diversified legumes, which is drought tolerant relative to other legumes. However, it is less popular as human food. This review focuses on providing details on the nutritional potential of underutilized Lablab varieties for food availability, accessibility and satisfactorily utilization for improved livelihood. So far research attention has been focusing on good agronomic performance with less information on their nutritional quality and its contribution to the wellbeing of people. Both wild and cultivated Lablab accessions do differ morphologically and across diverse habitat environments. This may make them less known, untapped and underutilized despite its promising potential as a food resource in developing countries where malnutrition still exists. Efforts are needed to popularize high-quality nutritional accessions, enhancing their consumption and commercialization for feeding the ever-increasing population in the future.
Potential of underutilized Dolichos lablab (lablab purpures) seeds in improving nutritional quality and livelihood in Tanzania
(NM-AIST, 2023-08) Minde, Josephine
Lablab is a climate-smart legume that is underutilized despite its potential for food, and income. Less research attention is linked to its underutilization limiting its contribution to achieving Sustainable Development Goals (SDG) 1, 2 and 3. This calls to search for synergies to the further improve Lablab utilization in Tanzania. Both qualitative and quantitative methods were employed. A total of 344 Lablab farmers and 40 traders were interviewed to collect information on knowledge, attitude, and practices (KAPs), Lablab value chain and dietary diversity from the selected districts in Morogoro, Manyara, Arusha and Kilimanjaro regions of Tanzania. A total of 30 accessions were collected from the local farmers and NM-AIST Genebank. The accession collected were evaluated for nutritional quality using standard methods. The best nutrient dense four accessions (D-394, ELD K2, HA-4 and D-96) were further used to formulate Lablab cookies. The study revealed that KAPs vary among farmers in Babati (39.6%) and Arumeru (27.3%). Arumeru had a positive attitude toward black accessions (80.2%) for marketing, whereas non black accessions were less well-known. Farmers were the primary actors, contributing for 70% of the natural assets for livelihood. Accession D-422 ranked higher in protein content by 28.3%. Sprouting significantly (p<0.001) reduced phytic acid in D-360 (64.6%), tannins in HA-4 (94.8%), and trypsin inhibitors (TIs). Fermentation significantly (p<0.001) decreases phytic acid by 75% in HA-4 and D-96, and tannin by 61% in HA-4 as well as trypsin TIs in ELD-K2, HA-4, and D-96 by over 90%. Furthermore, sprouted seeds had higher mineral concentrations in D-96 and HA-4, such as Mg (0.11-0.25%), (0.09-0.20%), and Zn (0.03-0.34%) and (0.23-0.32%), respectively, whereas fermented seeds increased Mg concentration in HA-4 from 0.09 to 0.23% and Zn content (0.23-0.35%). Lablab cookies made from HA-4 and D-96 fermented flours were highly preferred. HA-4 cookies scored the highest (> 8) similar to control. On the other hand, black Lablab's revenue contributed less to dietary diversity than nonfood commodities as per the Principal Component Analysis. Farmers' diets were over 90% cereal-based, with less Lablab-eating foods. The study concluded that wise income allocation is essential for both non-food items and nutritive food. Furthermore, the best accessions represent a diverse supply of high-quality food that, when fermented, greatly reduces anti-nutrients, yielding healthier and convenient nutritious foods. As a result, among the recommendations, value-addition and promotion of underutilized seeds could increase consumption and revenue, particularly for smallholder farmers in Tanzania.
