Oil palm is the major source of edible oil and feedstock consumed in the world. This study examined the determinants of global palm oil trade with attention to the effects of trade policies using a gravity model, PPML estimator, and the data from 1988-2020. Palm oil’s dramatic trade growth in recent years can be attributed to the economic growth of large countries, the proximity of partners and policies. Trade agreements increased crude and refined palm oil trade by up to 8 and 4 percent of the global import value, respectively. Further, the effects of policy changes due to COVID-19 and the recent export ban in Indonesia are also quantified.

The adoption of Conservation Agriculture (CA) technologies by smallholder farmers is expected to affect agricultural productivity and ultimately improve food security and farm incomes. However, there is still limited empirical evidence on the adoption and effects of CA technologies among smallholder farmers in the semi-arid areas of Tanzania. This study was designed to assess the adoption of CA by smallholder farmers in semi-arid areas. The study used a cross-sectional survey design in four villages in Chamwino districts where CA projects are promoted. A random sample of 260 households was interviewed in this study, including 134 CA adopters and 126 non-CA adopters. Data were collected and analyzed using KoBo and SPSS statistics respectively. Descriptive statistics were used to examine extension approaches applied and analyze the extent of CA adoptions. A logistic regression model explored the determinants influencing farmers’ decisions to adopt CA. In addition, two independent samples t-tests were used to calculate the effect of CA adoption on crop yields and farm incomes. The results show that robust extension services led to a better quality of CA practices on CA farms. Gender, access to extension services, access to agricultural inputs, participation in farmer groups, and access to credit for agriculture significantly influence the adoption of CA. CA adopters achieved better average crop yields and higher farm income per unit area than those who did not adopt CA. Thus, the study recommends that the government and other development actors devote more resources to agricultural extension services and mechanization to support and increase the scaling up of CA technologies. There is also a need to establish and strengthen monitoring and evaluation systems to ensure coherence, impact and sustainability of CF programs in semi-arid areas of Tanzania.

The purpose of the article is to assess the conditions and identify the features of the market for consumer and mortgage lending to households based on the economic and statistical analysis of the data panel. The instrumental and methodological apparatus of the article compiled general scientific principles and approaches to economic analysis: Scientific abstraction, analysis and synthesis, grouping, typology, comparison, qualitative and quantitative expert assessments; logical and contextual methods of processing theoretical material, as well as the method of economic and statistical comparisons. The article analyzes the dynamics of consumer and mortgage loans for households in Ukraine from 2007 to 2023, and highlights their socio-economic significance. The main problems in the field of consumer lending are formulated, the resolution of which is necessary for the intensive agricultural activity of households. It has been established that, despite the accumulation of certain experiences in the banking sector, the mortgage lending market has not become massive today. It is concluded that the reasons for this situation are the difficulty in the practical application of legislative regulations aimed at protecting the interests of creditors; high level of interest rates; low level of real income of households and, consequently, low effective demand for mortgage loans; the impossibility of mass provision of long-term mortgage loans due to high risk (interest, credit, legislative); almost complete exclusion of the state from participation in the formation of a civilized market for housing mortgage lending. The prerequisites for the further development of consumer and mortgage lending to households in Ukraine are formulated. The prospects for development and the main directions for improving consumer and mortgage lending to households are determined.

This paper analyzes the evolution and structure of Colombia's agricultural research network, paying special attention to the role of government expenditures in modeling this system. The authors also compare the Colombian agricultural network with the path followed by the Brazilian agricultural sector, which has been considered a pattern in South America. For this purpose, a bibliographic review and historical and institutional data are presented. Although agricultural research in Colombia began in the early 20th century, it has evolved more recently with the creation of different public and private institutions linked to the National Science and Technology System. However, agriculture and its research sector have faced major challenges related to government endowments that are needed to fund infrastructure and demand for researchers, as well as lower competitiveness compared to their Brazilian counterparts determined by social profit.

Global palm oil demand for energy, food, and chemical uses has led to a rapid expansion of tree plantations in Southeast Asia, Central Africa, Latin America and the Caribbean. This oil tree is the world’s most productive, highly profitable and traded vegetable oil crop, and the demand is expected to increase further in the near future. Nevertheless, oil palm expansion involves risks and nexus challenges. This work supports the idea that disruptive farming intensification, instead of land expansion, could scale up productivity, reducing the anthropogenic pressure on tropical forests and biodiversity losses. Findings from recent studies suggest that there is considerable scope for further yield improvements per hectare of palm oil with sustainable agronomic practices and farming intensification. Smallholder producers, agribusiness investors, civil society actors, NGOs, governments, researchers, and industry should make coordinated efforts with regulatory and support schemes and landscape design to increase yield and productivity with sustainable management practices and to achieve zero deforestation by protecting ecosystems.

The ever-increasing urbanization to accommodate the growing population reduces substantially the agricultural land but poses a threat to meeting the requirement of proper nutrition for human health. Mungbean [Vigna radiata (L.) Wilczek] is a unique gift bestowed by nature to mankind, which has the potency to make up the gap of protein shortage with an inexpensive cost, but due to its low level of production as well as productivity, which in a roundabout way influences the nutritional status of people resulting in malnutrition. Therefore, enhancement of the total area under mungbean cultivation is not permissible, and an increase in the total productivity per unit area is necessary. In this manner, screening and evaluation of improved genotypes for high yield are necessary to ensure food security. But at the same time seed yield being a complex character governed by several other contributing traits, selection for the characters proves to be quite challenging. As a prerequisite for any breeding program aimed at yield enhancement presence of significant genetic diversity in a given population is highly important. In the present investigation principal component analysis was performed and the results revealed two principal components contributing to the total variance in the population. While the PC1 was predominated by yield and its attributing traits, the PC2 was mainly comprised of growth-related traits. The hierarchical (UPGMA) cluster analysis using standardized data classified the fifty-two mungbean genotypes into 4 clusters, which showed 2 major, 1 minor and one outlier. Among them, cluster II is the most fascinating, as its individual had high seed yield plant–1 and related traits. The present work concluded that the identification of promising high-yielding mungbean genotypes through multivariate analysis has a good promise for future breeding programs with a view of food and nutritional security.

The past two decades have had times when grain cash and futures markets did not converge during delivery. What was the economic impact of this non-convergence on storage markets? To answer this question the supply of storage is estimated for corn, soybeans, and wheat. The lack of convergence is measured using a historical basis. The econometric model shows no relationship between the supply of storage and the lack of convergence. Thus, empirical results suggest that markets were able to adapt to the lack of convergence. Overall, the research indicates the resilience of storage markets to structural change.

Cluster-based improved sorghum (Melkam variety) production and commercialization was demonstrated in Nyanghtom Woreda of the South Omo Zone for one year (2021) to improve agro-pastoralists’ awareness, enhance the adaptation of full-package production technologies, and increase the economic visibility of improved sorghum cultivation. The production was started in a single kebele with a 7-hectare area of coverage. Twenty-five purposively selected direct beneficiaries and twenty-five randomly selected indirect beneficiaries from a neighbor were involved in the production. Direct beneficiaries cultivated sorghum on 0.28 hectares of land. At various stages of crop growth, monitoring, evaluation, and fieldwork were done by both beneficiaries and indirect beneficiaries. Face-to-face interviews with sorghum producers and non-producers were undertaken. Simple descriptive statistics were used to examine quantitative data, like grain yield, whereas the Likert scale was used for qualitative data such as agro-pastoralists perceptions. The result revealed that 30 quintal sorghum grain yield per hectare was obtained from improved sorghum (Melkam variety). The average return obtained from the sale of sorghum grain per hectare was 120,144 ETB. Agropastoralists’ perception result revealed that the “Melkam” variety is a higher yielder, and early matured as compared to local. Therefore, cluster-based sorghum production should be promoted for local sorghum growers in order to improve sorghum production sustainability and also seed system should take into account the provision of improved Melkam variety seed.

Optimization through cost minimization is a key strategy aquaculture feed producers adopt to ensure a continuous supply of fish in the global market. In light of this consideration, the study analyzed the economics of locally produced aquaculture feeds by complementing fishmeal with plant-based sources of ingredients. Specifically, the study estimated the cost and returns, socio-economic determinants of net income, and challenges of local feed production. Using a survey design, a case study approach was used to collect data from 36 aquaculture feed producers/millers. The data were presented using descriptive statistics, budgetary techniques, and two-stage least squares regression analysis. Key findings established that the majority (78.12%) of aquaculture local feed producers were men, and 43.75% had tertiary educational qualifications with a good number of years of experience. The profitability indicators show that aquaculture local feed production is profitable with 3.24% net returns on investment. The result further indicates that the incorporation of plantbased sources of ingredients reduced the utilization of Fishmeal (Clupeids) by 50%. Also, the regression analysis shows that the years of experience and initial capital investment were statistically significant (p < 0.05) determinants of net income while the major challenges in aquaculture local feed production were lack of perfect substitute for Fishmeal ( =2.94), government regulations on the harvest of Clupeids used for Fishmeal ( =2.91), poor access to capital ( =2.88) and high cost of machine spare parts ( =2.88). Based on the findings, it is recommended that fish nutritionists should intensify research on the production of fish feeds with a sole plant source of ingredients.
