Abstract

People in southwestern Bangladesh have been facing the waterlogging problem and protesting on the impacts for the nature for a long time. In the 1960s, the government introduced polders, embankments and cross dams to overcome the destructive scenario. Due to the failure of government initiatives, the local people of the coastal area cut into the polder so that the sediment deposited within the beel known as Tidal River Management (TRM). Then, TRM was applied several times in different catchments. The study was carried out from December 2018 to November 2019 to assess the positive and negative environmental and institutional impacts of TRM on Pakhimara beel in Tala Upazila (Sub-district), Satkhira District, by using the Sustainability Index of Tidal River Management (SITRM) framework. Sustainability Indices of TRM were designed to provide information on social, environmental and institutional gains. The environmental and institutional impacts were assessed by conducting household survey and Key Informant Interviews (KIIs). Agricultural impacts on crop, poultry, fisheries and vegetation, were also analyzed by comparing GIS map and agricultural production data (before and after TRM). This study investigated that Pakhimara beel was freed from waterlogging during the with-TRM event by 3,200 ha and the reduction of waterlogging increased agricultural land by 1,500 ha in 2018, compared to 2014. This study argued that only 54% of marginal farmers received crop compensation whereas 85% of crop production decreased due to TRM. For promoting sustainable TRM in the studied area, compensation should be guaranteed for all impacted parties, especially marginal farmers and the creation of employment opportunities, and settlement should be ensured.

Abstract

In the rapidly growing world, where farming land is shrinking due to horizontal urban expansion and development-induced projects, agricultural productivity should grow by 70% to meet food needs. Spatial urban expansion in developing countries, not exceptional to Ethiopia, puts immense pressure by taking peri-urban fertile agricultural land for the purpose of development. This paper examines whether urban expansion increases or decreases the agricultural technology adoption capacity of smallholder peri-urban farmers. Households were clustered into displaced and non-displaced, and data were collected from 341 households, 101 of whom were displaced and 240 households were non-displaced. Descriptive statistics and econometric model were employed to explore the role of urban expansion in technology adoption of smallholder peri-urban farmers. The multivariate probit result shows that urban expansion decreases the tendency of displaced smallholder peri-urban farmers to participate in irrigation and adoption of a generator but urban expansion does not increase or decrease displaced households’ tendency to adopt beehive and practice row sawing. Generally, urban expansion decreases the affinity of smallholder peri-urban farmers to adopt agricultural technologies. Therefore, policymakers, particularly the Bureau of Agriculture should intensively work and train displaced smallholder peri-urban farmers on the benefit of agricultural technologies to improve agricultural productivity and use the remaining plot of farmland sustainably. Besides strong monitoring and follow-up are required to avert the negative ramifications of development-induced displacement.

Abstract

The quality of potato seeds is important to support increased production. The majority of farmers do not certify potato seeds, which can result in various risks for potato seed production activities. This research aims to identify the risks of potato seed production and formulate risk control strategies for potato seeds production. The research uses house of risk method. The results of this study show thirty-nine identified risk events. The most impactful risk event was rotten potato. Thirty-two identified risk agents with two priorities must be handled first. The most effective ways in handling strategy are training, the certification of potato seed breeder farmers, potato seed certification, as well as purchasing breeder seeds from vegetable crop research center and from other seed breeders. This research suggests the needs to produce quality potato seeds by certifying potato seed and to update the competency certification of potato seed breeders.

Abstract

Banana is a horticultural plant with very high potentials, which contains carbohydrates and vitamins that are useful in fulfilling people's food and nutritional needs. Hence, this study aims to produce superior banana seedlings and develop a protocol for their mass production using a plant in vitro culture technique. This was a two stage-experiment i.e. microshoot production and plantlet formation. The result showed that Gebyar cultivar produced more shoots than the Kepok Kuning cultivar, with an average of 4.25 microshoots explant-1. However, Kepok Kuning produced more leaves than Gebyar, with an average of 4.64 leaves plantlet-1. Banana shoots cultured on the media containing Indole-3-acetic acid (IAA) at a concentration of 2.5 µM produced the highest leaves number. Meanwhile, those cultured on the media containing 1-Naphthalenesacetic acid (NAA) at a concentration of 7.5 µM produced the highest roots number. A Murashige and Skoog (MS) medium supplemented with 6-Benzylaminopurine (BAP) up to 30 µM and the one supplemented with 7.5 μM of NAA are suitable for Kepok Kuning and Gebyar cultivars micropropagation with regard to microshoot induction and plantlet formation, respectively.

Abstract

Rainfed lowland farming production is generally lower than irrigated lowland rice due to area differentiation regional features. Rainfed lowland rice farming can only produce rice during the rainy season because lowland rice cannot be planted in the dry season. The purposes of this study are (1) to analyze the risk of production and income of rice farming in rainfed lowland farming and (2) to investigate the factors influencing the risk of rice farming in rainfed lowland farming. Data were collected from 100 respondents of rice farmers in four sub-districts in Maros Regency using the multi-stage cluster random sampling technique. The analysis of production and income risks were performed using multiple linear regression with the heteroscedastic method. The results have shown that rice farming in rainfed lowland farming poses a risk to production and income. The variables that significantly influence the rainfed lowland rice farming are land area, the number of seeds, the amount of urea fertilizer and the amount of pesticide. Farmers are required to manage risk by prioritizing the effectiveness and efficiency production factors as needed. Similarly the government is expected to assist farmers in maintaining the level of rice selling prices.

Abstract

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.
