The Impact

The study was conducted to assess the impact of conservation agriculture practice on livelihood status of farmers in Bangladesh. A total of 300 farmers (50 focal, 100 proximal and 150 control) from five districts (Mymensingh, Bogra, Tangail, Sherpur and Jamalpur) were selected. Focal farmers were selected purposively; and proximal and control farmers were selected randomly. Descriptive statistics like sum, averages, percentages and ratios were calculated to evaluate the socioeconomic data as well as to identify the nature and extent of conservation agriculture practiced. Expenditure elasticity measured the responsiveness of change in expenditure of the farmers with change in income. Difference-in-difference (DID) analysis and Ravallion test were done to evaluate the impact of conservation agriculture practice on farmers’ income and expenditure. Multidimensional poverty index (MPI) was used to document the intensity of poverty. About 26.0, 25.0 and 18.6 percent focal, proximal and control farmers, respectively had basic knowledge about conservation agriculture practice; and 28.0, 19.0 and 15.3 percent, respectively received training on such practice. The adoption of different principles of conservation agriculture practice by focal farmers was satisfactory. The BCRs (Benefit cost ratio) for practicing conservation agriculture of focal, proximal and control farmers was 2.15, 2.07 and 1.92, respectively. The results of DID analysis and Ravallion test indicated that the impact of conservation agriculture practice on average annual income and expenditure of the farmers was statistically significant. The expenditure elasticity of focal, proximal and control farmers was 0.31, 0.44 and 0.58 percent, respectively. A remarkable improvement in farmers’ livelihood status was found after adopting conservation agriculture practice. Input support, motivation, training programmes and extension services by different government and non-government organizations should be properly implemented to raise the awareness and enrich the knowledge of the farmers on conservation agriculture practice.SAARC J.

The study was conducted to assess the impact of conservation agriculture practice on crop profitability in Bangladesh and to identify the determinants of adopting such practice. A total of 300 farmers (50 focal, 100 proximal and 150 control) from five districts (Mymensingh, Bogra, Tangail, Sherpur and Jamalpur) were selected. Focal farmers were selected purposively; and proximal and control farmers were selected randomly. Descriptive statistics like sum, averages, percentages and ratios were calculated to evaluate the socioeconomic data. Profitability of crop production was measured in terms of gross return, gross margin, net return and benefit cost ratio (BCR). Crop productivity was measured using the Enyedi’s crop productivity index. The BCR of focal, proximal and control farmers were 2.58, 2.24 and 2.18, respectively. The crop productivity of focal, proximal and control farmers were increased by 0.5, 1.1 and 1.4 percent, respectively with respect to the entire region. Educational level of household head, farm size, farm income, extension contact and farming experience were found as significant factors through logit model that affect the adoption of this practice by the farmers. Input support, motivation, training programmes and extension services by different government and non-government organizations should be properly organized and implemented to raise the consciousness and enhance the knowledge of the farmers on conservation agriculture practice.J.

The Impact

More than ever before, engineers are creating products for developing countries. One of the purposes of these products is to improve the consumer’s quality of life. Currently, there is no established method of measuring the social impact of these types of products. As a result, engineers have used their own metrics to assess their product’s impact, if at all. Some of the common metrics used include products sold and revenue, which measure the financial success of a product without recognizing the social successes or failures it might have. In this paper we introduce a potential metric, the Product Impact Metric (PIM), which quantifies the impact a product has on impoverished individuals — especially those living in developing countries. It measures social impact broadly in five dimensions: health, education, standard of living, employment quality, and security. The PIM is inspired by the Multidimensional Poverty Index (MPI) created by the United Nations Development Programme. The MPI measures how the depth of poverty within a nation changes year after year, and the PIM measures how an individual’s quality of life changes after being affected by an engineered product. The Product Impact Metric can be used to predict social impacts (using personas that represent real individuals) or measure social impacts (using specific data from products introduced into the market).

A conceptual model for analyzing the dynamics of the value of the project, achieved as a result of engineering, under conditions of uncertainty has been developed. In the methodological context, the proposed approach is based on an array of isovalues, each of which corresponds to its own level of optimism in forecasting the cash flow for the project. With the increase in the efficiency of the project due to engineering, the entire array of iso-value lines’ changes its geometrical position, moving further from the origin (in the four-dimensional space "time-benefit-cost-risk"). The proposed model includes three stages. At the first stage, input information is collected and the corresponding analysis is initiated. The result of the second stage is a multivariate cash flow forecast and calculation of the benefit-cost ratio (BCR) and its changes for each scenario. The third stage provides the calculation of the expected BCR and its change, an assessment of the risk of making an erroneous decision and changing this risk as a result of the engineering session. The model makes it possible to calculate the achieved proportion of the static and dynamic vectors of change in the value of the project, which is one of the key manifestations of the scientific novelty of the work. In the example considered, the share of the dynamic vector of growth in the value of the project was found to be 35.47 %. The model has an environmental property - the assessment of the success of value engineering under conditions of uncertainty is carried out on the basis of the annual total benefits and the annual total costs throughout the project cycle. Thus, the analysis takes into account the impact of the project on the environment, which is reflected in the risk assessment. The given case testifies to the feasibility of applying the model in the practice of engineering the value of construction projects.

Integrated multi-trophic aquaculture (IMTA), farming of species from different trophic levels and with complimentary ecosystem function, is regarded as a suitable approach to develop a sustainable aquaculture system. In order to establish an IMTA system, a study was carried out in Sindhudurg District, Maharashtra, India for selected tropical brackish-water species. Two equal sized pens (250 m2) were constructed for IMTA and control respectively in each land based system and open water cages were set in the estuary. Different combinations of fed species (Chanos chanos, Etroplus suratensis, Mugil cephalus, Penaeus indicus) and an extractive crop (Crassostrea madrasensis) were stocked in IMTA experimental system whereas monoculture of P. indicus served as control. Water quality characteristics were found to be within the admissible limits. Soil organic carbon was found to be lesser in the IMTA system compared to control. The productivity of IMTA system was higher than control: 3250 kg h-1 vs 2000 kg ha-1. Further, income and benefit-cost ratio was found to be higher in IMTA pens. The present study concludes that IMTA is a possible option for system diversification as well as species diversification without compromising economic profitability of culture.

Residue Retention

A two year longer on-farm research on conservation agriculture was conducted at Bhangnamari area of Bangladesh during November-June in 2014-15 and 2015-16 to evaluate the performance of non-puddled rice cultivation under increased crop residue retention. The rice variety BRRI dhan28 was transplanted under puddled conventional tillage (CT) vs. non-puddled strip tillage (ST) with 50% standing residue (R50) vs. conventional no-residue (R0) practice. The treatments were arranged in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2014-15. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher BCR. Retention of 50% residue increased yield by 3% over no-residue, which contributed to 10% higher benefit-cost ratio (BCR). Results of this two year on-farm study confirmed that the ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to produce the highest BCR (1.06).

An experiment was conducted at Salyan, Nepal to assess the mother rhizome retrieval and organic treatment of the same retrieved plant on economic yield of ginger during 2015/16.‘ Kapurkot Aduwa-1’, a superior Nepalese variety was used for this experiment. Two dates i.e. 1 September and 7 September were used as a time of retrieval factor and seven organic treatments i.e. Trichoderma, Jeevatu, Bordeaux paste, mixture of neem and timur dust, vermicompost, jholmal and control as second factor and these 14 treatment combinations were laid out in factorial randomized block design with three replications. The plant height, leaf number, tiller number was found to be significantly highest with vermicompost treatment on all days 5 days interval after harvesting of the mother rhizome whereas the lowest was observed at control. The mother rhizome yield and fresh rhizome was found to be significantly highest on vermicompost applied field with 1.7 t/ha and 22.8 mt/ha respectively and lowest fresh rhizome yield (15.5. t/ha) was found with control. The disease yield was significantly lowest (0 t/ha) and highest (0.2 t/ha) with the control. Benefit cost ratio was found to be significantly highest (1.74) and lowest at control (1.32).

Okra is one of the most important summer vegetables in South Asian countries including Nepal. However, the damage by insects like Jassid (Amrasca biguttula Ish.) and whitefly (Bemisia tabaci Guen) has resulted in significant reduction of its production. An experiment was conducted based on intercropping taking okra (Abelmoschus exculentus L. Moench) as the main crop in Arghau, Lekhnath-27, Kaski, Nepal from March 4 to May 24, 2018. The intercrops used were coriander (Corriander sativum), carrot (Daucas carota), fennel (Foeniculum vulgare) and parsley (Petroselinum crispum). The population of jassid and whitefly was recorded from three leaves representing the different strata (bottom, middle and top) of the vegetative parts; and related yield parameters were also observed to correlate with the level of population incidence of these pests. Least numbers of jassids (5.50±0.29, 6.94±0.43, 8.00±0.41 and 3.69±0.76) were observed respectively at 30, 40, 50 and 60 days after sowing (DAS) in okra+ coriander. Likewise, okra + coriander intercropping was effective in inhibiting the population of whitefly (7.50±0.59, 8.56±0.19, 10.25±0.66 and 7.06±0.42) at 30, 40, 50 and 60 days after sowing (DAS) respectively. In contrary, the highest number of jassids and whiteflies were observed in okra + parsley and control (okra only). Both pod length (cm) and yield (t/ha) were the highest (17.92±0.57 and 28.20±0.49 respectively) in okra + coriander and were the lowest (16.42±0.21 and 27.58±0.39 respectively) in okra + carrot. The benefit-cost ratio was in order okra + coriander > okra + carrot > okra + fennel > okra + parsley > control (okra only). Among the different intercrop combinations, the okra + coriander was found most effective that could be suggested as one of the alternative strategies to limit the population of pests; jassid and whitefly in okra.

Rating Scheme

The newly established New Car Assessment Program for Southeast Asian Countries (ASEAN NCAP) has incorporated Safety Assist Technologies (SATs) in its automobile safety rating scheme. In order for any assessed car to be eligible for the maximum 5-star rating, it should first be equipped with Electronic Stability Control (ESC) and fitted with seatbelt reminder (SBR). However, since these SATs are not being evaluated in their performance by the means of field testing, this paper explains the benefit of having these SATs through Cost-Benefit Analysis (CBA) which help to rationalize the importance of SATs in preventing road accidents or mitigating severity of injuries. Due to data limitation, this preliminary CBA assessment will only be focusing on Malaysia’s situation and is based on published sources and the authors’ best estimates. This study also includes the Cost-Benefit Analysis on Anti-lock Braking System (ABS), which is the basis for ESC technology, in preparation for its inclusion in the future rating scheme to expedite the vision of making ABS as standard fit in all ASEAN’s passenger cars. The preliminary result shows that all technologies – ESC, SBR and ABS – appear to be cost-effective (benefit/cost-ratio > 3) or most likely cost effective (1 < benefit/cost-ratio < 3) in Malaysia’s road safety situation per se.
