Land-based investment implications on land use land cover change and livelihood of the local community in Northern Amhara Region, Ethiopia

2023-10-27T09:24:07+00:00

A surge in land-based investment has been taking place in developing countries, including Ethiopia, with the aim to foster economic growth, enhance food security, and reduce poverty. This study sought to investigate the impact of such investments in the western Armachiho district of the Amhara Regional State, Ethiopia, using remote sensing data from 1995, 2010, and 2020 supplemented by socioeconomic surveys and field observation to validate the spatial data. The results revealed significant land use and land cover changes in the district over the past twenty-five years. Forest cover decreased from 60.92% in 1995 to 27.6% in 2010, while water bodies, including rivers, streams, and ponds, declined from 3.04% to 1.4% during the same period. Conversely, built-up areas, bushland, farmland, and bare land exhibited an increasing trend. The observed changes during the initial study period can be attributed to the expansion of land-based investments and illegal farmland encroachment in the area under investigation. The results further indicated that the expansion of such investments during this period had adverse effects on the local community, resulting in the loss of access to farmland, grazing land, and forest products that served as sources of income. The results also demonstrated that the delineation of agricultural investment land, the closure of unproductive land, and the issuance of land-holding certificates have prevented illegal encroachment that contributed to the improvements in forestland cover between 2010 and 2020. Hence, when granting significant amounts of land for land-based investment, it is crucial to consider not only the short-term economic benefits but also the well-being of local communities and the principles of environmental sustainability.

Indiscriminate use and inappropriate application of agrochemicals by smallholder farmers in Amhara Region, Ethiopia: Implications for sustainable beekeeping, crop and livestock production

2023-10-26T13:39:54+00:00

This study was conducted to investigate the knowledge gaps regarding the use of agrochemicals by the farming communities in the Amhara Region, Ethiopia and its impact on beekeeping, crop and livestock production. The primary data were collected through household surveys, key informant interviews, focus group discussions and researchers’ observations. A total of 540 farmers (270 beekeepers and 270 non-beekeepers) were interviewed using a semi-structured questionnaire. The survey data was analyzed using SPSS software version 21, while the qualitative data was analyzed using content analysis. The results revealed that beekeeping contributes significantly to the livelihoods of smallholder farmers in the Amhara Region, mainly through the provision of hive products for home consumption and income but also for pollination services. The trends in the past decade showed that honeybee colony holdings and hive productivity had decreased due to indiscriminate use of agrochemicals, among others. Both beekeeper and non-beekeeper farmers in the study areas have been using different types of agrochemicals to control crop pests, diseases and weeds, and in some areas farmers used herbicides to clear weeds from pastureland. Farmers also stated that they are already aware of the negative effects of agrochemicals on honeybees. Nevertheless, the applications of agrochemicals are continuing without attitudinal changes. The results also showed that farmers purchase agrochemicals from legal as well as illegal vendors without proper understanding of their safe use and the expiry dates. Farmers’ use of agrochemicals in violation of the technical recommendations on their proper applications; they ignore risks and safety instructions, use unsafe storage facilities, do not use protective devices when applying agrochemicals, and dispose of agrochemical containers unsafely. The findings demonstrated that apart from the direct effects on honeybees, indiscriminate and inappropriate application of agrochemicals even poses risks to the lives of farmers. Beekeepers, non-beekeepers and both crop and livestock experts revealed that nowadays IPM has not been used by farmers as an alternative to synthetic agrochemicals. Farmers are also unaware of the legal frameworks available to protect honeybees from the negative effects of agrochemicals, and they have not developed local bylaws that can be used by farming communities to protect honeybees from the negative effects of agrochemicals. The results also showed that the direct economic losses incurred due to the loss of honey bee colonies from the indiscriminate application of agrochemicals run into ETB 11,520,000.00 /USD422,133.00/. Thus, the indiscriminate use of agrochemicals has become one of the major threats to the development of beekeeping, crop and livestock production. Therefore, very strong actions are needed by concerned and responsible stakeholders to save the lives of honeybees. The interventions to reduce agrochemical exposure should be implemented through context-specific and integrated approaches.

Management practices and cow comfort of crossbred dairy cows in youth managed dairy farm enterprises, South Gondar Zone, Amhara Region, Ethiopia

2023-10-28T09:07:21+00:00

Good dairy farming methods and cow comfort are essential variables in reproductive efficiency, milk output, milk quality, and dairy cow health. The purpose of this study was to look into the management techniques and cow comfort status of crossbred dairy cows in youth managed dairy farm enterprises in Ethiopia's Amhara region's South Gondar zone. All (20) youth-managed dairy farm enterprises were chosen and questioned using a pre-tested semi-structured questionnaire, and all (204) lactation dairy cows were chosen for cow comfort assessment. The SPSS version 22 program was used to analyze the data. According to the findings, the most common feed sources used for their dairy cattle were formulated and unformulated agro-industrial byproducts followed by non-conventional and hay. Piped (35%) and bore (30%) water were the most common water sources for dairy cattle, with the majority of farms allowing free access to water. The majority of dairy farm firms (70%) uses artificial insemination as well as bull services. The majority of dairy farm enterprises (55%) had shared sheds, followed by individual sheds (45%) built with government assistance (55%), and family (30%) with the same design and construction. The challenges confronting dairy farm enterprises were ranked feed scarcity and high feed costs first, followed by a lack of access to land, a lack of access to markets, and a lack of credit, whereas the opportunities for dairy farm enterprises were ranked first increased demand for milk and milk products first, followed by rapid urbanization, rapid population growth, and the availability of cheap labor. The vast majority of cows (92%) were severely lame, followed by moderate lameness (83%) and the vast majority of cows (52.5%) had moderately injured legs, followed by severely injured legs. The udder and leg cleanliness of most cows was mid cleanliness (52.7%), as opposed to dirty (30%) and clean (17.2%) with a low cow comfort index (0.48). The mean stall length, bed length, brisket board height, neck rail height, lung space, feeder height, and feeder width were 239±16 cm, 222.7±28.3 cm, 10.5±3.6cm, 61.5±15.3 cm, 128.15±21.5 cm, 40.6±8.7 cm, and 36.7±6.9 cm, respectively. The results also revealed that the overall floor softness scored marginal (45%) softness rather than hard (30%) and normal (25%) floor softness. The majority of dairy farm enterprises (55%) did not provide bedding material for their cows and, the bedding materials include straw, hay, and sawdust. Bedding materials are renewed once a month (37.5%), twice a week (37.5%), and once a week (25%). The frequency of manure removal was twice daily (60%), three times daily (30%), and once daily (20%). The findings revealed that the cow’s comfort status is poor, so it is recommended that the barn be renovated routine management practices be improved, and assistance from the government and other relevant stakeholders is required in order to obtain credit to renovate the cow barn and improve management practices.

Characteristics of the cattle fattening system and body conformation of beef cattle in Bahir Dar Special Zone, Amhara Regional State, Ethiopia

2023-11-10T09:06:57+00:00

The study was conducted in the urban and peri-urban areas of Bahir Dar special zone, Amhara Regional State, Ethiopia, with the objectives of characterizing the cattle fattening system and conformation traits of fattening cattle in the area. Data on the fattening systems were collected from 112 cattle fatteners (72 from peri-urban and 40 fatteners from urban areas) who have experience with cattle fattening using a semi-structured questionnaire. The beef cattle conformational traits measurement was carried out on fattening cattle on a total of 60 animals (30 from peri-urban farms and 30 from urban farms) in selected farms under the fattener’s management condition. Twelve farms were used for the body conformation measurement of the animals using ICAR guidelines. The survey data was analyzed and summarized using descriptive statistics and index ranking. Conformational trait data were analyzed using the General Linear Model Procedure of SAS 9.1. The overall mean family size, age of household heads, and landholding per household were 8.43, 42.31 years, and 0.77 hectares, respectively. Most of the respondents in the periurban hold cattle for draft power (index = 0.40). The respondents prefer intact and matured bulls in the urban (100%) and peri-urban (93%) areas. The respondents, on average, fatten three times a year (47.3%) with a mean number of 8.08 fattening cattle. The main feed sources in the peri-urban and urban areas were crop residue (index = 0.26) and agro-industrial by-products (index = 0.63), respectively. Most of the cattle fatteners select their fattening cattle based on body conformation (index 0.29) and condition (index 0.21). The mean initial and final body weight of fattening cattle were 348.75kg and 425.33 kg, respectively. In general, the cattle fattening practice needs to be supported by the extension system so as to efficiently use the resources.

Revitalizing community forestry in the Amhara Region of Ethiopia: A property right perspective

2023-11-13T14:54:34+00:00

Severe deforestation, land degradation, and the lack of forest products in Ethiopia have necessitated the implementation of a community forestry program since the 1980s by mobilizing the local communities. However, there have been incidents indicating that many of the community forests are either degrading or remaining unproductive. While community forests are, in principle, the collective property of the local community, empirical evidence concerning how property rights impact their management and their role in enhancing rural livelihoods and environmental rehabilitation is lacking. This study aims to investigate the performance of community forestry through the lens of property rights and tenure security, in order to uncover the challenges impeding community forestry in Ethiopia, with a focus on community forests in the Amhara Region. The study gathered primary data on community forest management from two community forests located in East Gojam and North Wollo, using questionnaires, focus group discussions, key informant interviews, and field observations. Additionally, secondary data on legal frameworks were collected from institutions involved in community forestry. The data analysis employed descriptive statistics and thematic analysis. The findings of the study revealed that a majority of respondents (91%) lacked clarity regarding the objectives of establishing community forests, and about 95% claimed that community forests belong to the state. These incidents have led to diminished interest in continuing the program. The study highlighted that the community forestry program suffers from inadequate policy and legal provisions, chronic institutional instability, overlapping mandates, and limited community engagement. These factors have weakened property rights, which are reflected in tenure insecurity and the absence of individual household benefit packages. Consequently, it can be concluded that community forest interventions have been promoted based on general belief in the importance of trees for rural livelihoods and ecosystem rehabilitation, rather than as part of a deliberate and directed policy and strategy. In summary, revitalizing community forestry in Ethiopia necessitates a thorough understanding of property rights and tenure security issues. In this regard, it is imperative for government agencies to enact a clear national strategy for community forestry development and adopt a supportive role to enable communities to establish robust community forestry institutions to safeguard their rights while fostering community forestry and environmental protection activities.

Productivity, economic performances and survivability of exotic chicken breeds under small-scale chicken production system in South Gondar zone, Ethiopia

2023-11-10T08:59:46+00:00

The study was conducted to evaluate the growth, survivability and egg production performance of Bovans Brown and SassoT44 commercial chicken breeds reared in small-scale chicken production enterprises in selected districts of South Gondar Zone in Ethiopia. A multi-stage sampling technique was used to collect data in the year 2019. A total of 21 small-scale chicken farms and 350 chickens were selected for the survey and monitoring-data collection, respectively. The survey data was analyzed using SPSS Version 20 and the GLM procedure of SAS 9.2 was used for the monitoring data. The majority of the producers (71.4%) reared Sasso T44 breed. Most of the farms (90.5%) used commercial feed even though they are challenged by feed shortage and increased feed cost. The interaction effect of breed-district was significant on the body weight and daily weight gain of chickens that the body weights of Sasso T44 chickens at different ages in Addis Zemen district was significantly higher than the other two districts. The overall mortality rate of the chickens up to the 22th weeks of age was 13.2% and 11.5% for Sasso T44, and Bovans Brown, respectively. The average egg production per hen up to the 45^th weeks of age was significantly (P<0.05) higher for Bovans than Sasso T44. The overall hen day egg production in the first phase (up to the 45^th weeks of age) was 65.6% and 57.8% for Bovans Brown and Sasso T44, respectively. There was a significant difference (P<0.0001) in age at first egg between the two breeds that Bovans Brown (132 days) was better than Sasso T44 (164 days) breed. In general, chicken in Addis Zemen performed better both in growth and egg production. Sosso T44 breed was better in growth performance while Bovans Brown were better in egg production traits.

Resettlement and land rights: Implication on land use and land cover change in Ethiopia

2023-11-08T09:31:01+00:00

In Ethiopia, resettlement schemes have been widely implemented in response to famine and food insecurity. Since 2003, planned resettlement initiatives have been carried out, considering farm households’ willingness as a pivotal factor. To enhance the attractiveness of the resettlement program, the Amhara regional state attempted to offer resettlers dual landholding rights. These rights encompassed perpetual landholding in the new settlement and a three-year guarantee against losing their landholdings in the old settlement if they chose to leave due to discomfort. This study aimed to address conceptual and empirical gaps in understanding the relationship between the resettlement process, land rights/tenure, and changes in land use and land cover (LULC) within this new approach. The goal was to provide policy directions. Employing a socio-spatial research methodology, data was generated using GIS techniques, questionnaires, and focus group discussions. The study found that unrestricted encroachment into woodlands and grazing lands has led to severe LULC changes in the study area. The land use land cover change analysis between 2003 and 2016 indicated that the forest cover and bushland decreased by 3,879.18 ha and 2,810.16 ha respectively, and conversely farmland has increased by 5,814.09 ha. Furthermore, due to the absence of clear property rights definitions and the provision of dual land rights, many resettlers opted to maximize benefits from both land possessions rather than establishing a settled life in the new settlement area. Despite the innovative nature of the resettlement program with its focus on providing dual land rights to relieve pressure in degraded highlands and transform livelihoods in more productive lowland areas, the initiative faced challenges in controlling land rights and management issues in both the old and new resettlement areas. Observations in these areas contradicted the presumption of the new resettlement policy, aiming to bolster farmers' livelihood security and environmental protection. This study underscores the intricate and multi-dimensional nature of the relationship between resettlement, land rights/tenure, and LULC changes in Ethiopia. To ensure the success of innovative resettlement programs, robust institutions supported by policy frameworks that comprehensively consider social, economic, political, and technical elements impacting resettlement are imperative. The study also recommends the implementation of a consolidated land governance system from the outset, complemented by a strong monitoring and evaluation system, to effectively address resettlers' land rights and obligations, thereby improved livelihoods and efficient land use and management could be advanced in the settlement areas

Optimizing seeding rates for irrigated bread wheat (Triticum aestivum L.) varieties in the lowland area of Jawi, northwestern Ethiopia

2023-10-28T08:44:48+00:00

Bread wheat (Triticum aestivum L.) is one of the main food security crops in sub-Saharan Africa. The Ethiopian government is putting a great effort into increasing the production of bread wheat under various production systems to narrow the gap between demand and supply. There is no agronomic recommendation for wheat production produced under irrigation conditions. Thus, this study was initiated to identify the optimum seeding rates of different wheat varieties for the highest-yield and profitability in the lowland area of northwestern Ethiopia under irrigation conditions in 2020/2021. The experiment was laid out using a randomized complete block design with three replications. The treatments are five levels of seeding rates (100, 125, 150, 175 and 200 kg ha^-1) and three bread wheat varieties (Fentale-2, Kakaba and Ogelcho). Wheat yield and yield component data were statistically subjected to analysis of variance using SAS-JMP-16 software. Results revealed that the performance of wheat varieties in the lowland area of Jawi was promising irrespective of their yield differences. The study showed the highest number of total and effective tillers per unit area; and biomass and grain yield were recorded when varieties Fentale-2, Kakaba and Ogelcho were planted at a seed rate of 200 kg ha^-1, 175 kg ha^-1 and 200 kg ha^-1, respectively.The same varieties gave a grain yield of 3.99 t ha^-1, 3.47 t ha^-1 and 3.44 t ha^-1, respectively. On the other side, maximum net benefit and marginal rate of return were obtained when the variety Fentale-2 was planted at a seeding rate of 200 kg ha^-1 (NB = 65,778.8 ETB ha^-1and MRR = 224 %) followed by the same variety at the seed rate 175 kg ha^-1 (NB = 63,402.4 ETB ha^-1and MRR = 297 %). Thus, it can be concluded that planting variety Fentale-2 with 200 kg ha^-1seed rate under irrigation condition is the promising agronomic practice in lowland agro-ecology of Jawi area. However, further research is also recommended by considering the appropriate planting time and the irrigation water requirement.

Seed tuber cutting improves tuber yield of potato (Solanum tuberosum L,) varieties under irrigation conditions in Dangla district of Amhara Region, Ethiopia

2023-11-11T12:06:29+00:00

Potato (Solanum tuberosum L.) is an important cash and food crop in Ethiopia. However, lack of planting material and improved varieties are among the major factors affecting its productivity. Therefore, an experiment was conducted at Gayeta Kebele of Dangla district, Awi Zone, Northwestern Ethiopia to study the effect of seed tuber cutting on yield and yield components of potato varieties under irrigated conditions. The experiment consisted of two improved varieties (‘Belete’ and ‘Jalenie’) along with one local variety and two tuber size categories and their half cuttings (whole large tuber (>75g), whole-medium tuber (39-75g), half cuttings of large tuber and half cuttings medium tuber. It was arranged with a factorial combination in RCBD with three replications. Phenological, growth, yield and quality parameters were significantly affected by the main factors (cutting and variety). Whole-large and half-large tuber sizes and Belete variety showed superior performance on marketable (38.24 t ha^-1) and total tuber yield (40.26 tha^-1) over the rest of the tuber sizes and varieties. The combination of Belete variety with whole-large seed tubers recorded the highest net benefit 261,516 ETB ha^-1 with an acceptable marginal rate of return (113.6%). The second highest net benefit (247,001.3 ETB ha^-1) with an acceptable marginal rate of return (2566.67%) was recorded when Beltete variety was planted using half-large cut tubers. Hence, Belete variety with whole-large seed tubers, and half-large cut tubers could be recommended for resource-rich and poor farmers, respectively, for the production of potatoes under irrigated conditions in Gayeta kebele and areas with similar agro-ecology. Repeating the research in different seasons and locations is also recommended.
