Banana is an important food and cash crop and constitutes a large proportion of the total crop production in East and Central African (ECA) countries. Banana production has been threatened by Xanthomonas wilt (BXW) disease caused by the bacterium Xanthomonas campestris pv. musacearum. Besides being a threat to food security in the region, the disease has severe economic implications, which emanate from yield losses and management costs. Without proper management, yields in affected areas are reduced to zero. Management approaches of the disease include use of cultural practices and awareness creation among the stakeholders along the banana value chain. These efforts to control the disease produced partial results, and the disease has continued to encroach into previously disease-free areas and to resurge in areas where it had been controlled. One of the major challenges to sustainable management of the disease has been poor understanding by stakeholders of the factors influencing disease spread and severity. Awareness creation among stakeholders has not been sustained due to limited technical, financial and infrastructural capacity. Incorrect application of cultural practices and lack of appropriate methods for field disinfection of tools coupled with weak institutional frameworks for enforcing byelaws and quarantine measures are key drivers to the continued presence of the disease in ECA. It should however be emphasized that no single management option is adequate to sustainably manage the disease. In this paper, we review mechanisms of disease transmission and drivers of the continued disease presence, and suggest approaches for sustainable management of BXW.

Banana is a key crop in the livelihoods of many people in the Great Lakes region of East and CentralAfrica. For more than a decade now, the crop has been threatened by Banana Xanthomonas Wilt (BXW) which has spread throughout the region but at different rates. The disease attacks all banana cultivars and can cause up to 100% yield losses at farm level if effective control measures are not put in place. However, limited information on impact of BXW at regional level is available to guide interventions. Thus, this study assessed the impact of BXW on farmers' livelihoods in Kagera basin of Tanzania, Burundi and Rwanda. A total of 436 households (Tanzania 120, Burundi 208 and Rwanda 108) mostly from major banana-producing and BXW-affected districts were sampled and interviewed in a household survey. Thirty-three to seventy-five of the total banana mats per farm in the three countries were infected with BXW. Banana production losses caused by BXW were valued at US$ 10.2 million and US$ 2.95 million in Tanzania and Rwanda, respectively, banana sales by farmers dropped by 35% while bunch prices unpredictably doubled. Since banana is a key component of these farming communities, the banana production losses resulted in significant reduction in household food security and incomes. To cope with these challenges, most households are diversifying into other food crops such as maize, cassava and sweet potatoes. This poses a number of socio-economic and biological implications that require further investigation.

The study was on socioeconomic factors influencing the uptake of coffee production recommended practices in the Kichwamba and Kirugu Sub-counties of the Rubirizi district and was conducted in February 2021. Objectives were to identify the coffee production systems and practices used, identify the socioeconomic challenges associated with the uptake of recommended practices for coffee production, and identify the policy interventions to address the challenges associated with the use of recommended coffee practices. Farmers continue to register low coffee yields hence affecting their livelihoods and incomes and achieving maximum coffee production requires that farmers apply recommended practices since the quantity and quality of the crop rely on the practices used. A cross-sectional survey was conducted using simple random sampling and a total of 376 coffee farmers were sampled. Results indicated that Arabica coffee commonly grown has two major systems intercropping and mono-cropping. The coffee-recommended practices used were weeds control (23.7%), shading (21.5%), pruning (15.5%), fertiliser application (14.1%), pest and disease management (12.2%), water drainage management (6.6%), transplanting (4.0%), and seedbed preparation (2.7%). Statistically significant socioeconomic factors affecting the uptake of recommended practices for coffee were age [p=0.014], education level [p=0.002], labour [p=0.005], Farm size [p=0.001], farming experience [p=0.031], gender [p=0.031], land slope [p=0.048], un-accessibility to credit services [p=0.032], and plot ownership [p=0.049]. Policy interventions were farmer capacity building (35.1%), strengthening agricultural extension (23.7%), credit extension to the farmers (15.7%), re-visiting land reform policies (13.6%), and group formation (11.9%). The study concluded that coffee in the study area was grown under two production systems; intercropping and mono-cropping; the major coffee recommended practices used were; seedbed management, transplanting, pruning, shading, fertiliser application, weeds control, pest and disease management, and water drainage management. Socioeconomic factors like Education level, shortage of labour, farm size, experience in farming, gender, the slope of the land, un-accessibility of credit services, farmer age and plot ownership type were significant socioeconomic factors affecting uptake of recommended practices. Suggested policy interventions were re-visiting land reform policies, credit extension, capacity building, strengthening agricultural extension, and farmer group formation. More education and training for farmers, revisiting land policies, groups, associations and cooperative formation, and credit services extension are recommended.

Uganda has significantly continued to receive a large number of refugees in the region and this is positively correlated with its proportional increase in peace and stability. The presence of favorable climatic conditions enhances agricultural productivity and this has triggered redirecting refugees into agricultural production as the major source of livelihood. However, in Ugandan setting, it has not yet been clearly established how agriculture has practically enhanced the livelihoods of the refugees. The study therefore aimed at identifying the agricultural activities practiced by refugees living in Nakivale refugee settlement, identifying the challenges faced by refugees involved in agriculture and their possible solutions as well as examining the contribution of agriculture towards livelihoods of refugees in Nakivale Refugee settlement. The study utilized a case-study approach to analyze the contribution of agriculture in the enhancement of livelihoods in the context of a single settlement and a sample size of 80 respondents was chosen using simple random sampling and an interview guide was used to collect primary data from the respondents. It was revealed from the study that crop production is the main agricultural activity practiced by refugees living in Nakivale refugee settlement in a bid to improve on their food security and household incomes. The study further revealed that climate change, diseases/parasites and diseases, limited land and low prices for the produce are the most serious challenges facing refugees' farmers. It is concluded that food security in Nakivale refugee settlement is rather influenced by agricultural production and the associated dynamics that ultimately determine the well-being of the refugee communities. It is important to appreciate that any variation in factors of production, weather and produce prices will determine livelihood status of the community for such a specific period of time. It's recommended that farmers should adopt climate smart farming to mitigate effects of climate change, supporting

The main concern in agricultural research is to ensure that research products are adopted by farmers. However, the rate of adoption is low. Most research on adoption rates are post-ante. The values of such research can be added if factors for adoption are ex-ante identified and measures taken to increase adoption. This study was conducted in Morogoro, Tanzania to ex-ante identify socio-economic characteristics that influence adoption of Integrated Lowland Rice Legume Technologies (ILRLT). The ILRLT included integration of rice (SARO variety), legumes (cow pea) water management (irrigation, rainfed and majaruba bunds), tillage (conventional and minimum) and fertilizers (UREA, TSP and MOP). Data were collected through questionnaire interviews to 200 representative farmers and key informants. Descriptive statistics, Multi-Criteria Analysis and a two functions adoption model were used to assess the suitability of ILRLT and analyze the likelihood of farmers to adopt. Results indicated that important criteria for rice variety preference and hence adoption are high prices (7.8%), good taste (6.1%), early maturity (4.8%), disease (3.2%) and drought tolerance (17.4%). ILRLT scored more (26.40%) than farmer's (17.97%) in fulfilling criteria for rice legume variety preferences. ILRLT have a chance of being adopted to the maximum rate of 89.7%. Adoption is likely to be more with farmers who depend on irrigation than those who depend on rainfed rice farming.
