Monsoon rains provide relief from the sweltering summer heat conditions, replenish depleted profile moisture to breathe new life in soils. With appropriate management of rain water, Indian summer monsoons boost the level of ‘reservoir of life’. Our inability to manage spatial and temporal rainfall variation features of deficit and excess rainfall episodes and their interactions with soil variability is a major cause of uncertainty in agricultural production. In the past, entire focus of national efforts was on rainwater harvesting, storage and distribution through canal networks and greater reliance on ground water pumping to meet immediate crop water demands. These approaches have resulted in wide spread problems of natural resource fatigue and unsustainable water supplies. This paper analyses the complexities of climate change-land degradation-food security nexus and suggests the need for adopting alternate approaches emphasising on in situ conservation of rain water and its efficient use such as to reverse the processes that contribute to land degradation in specific landscapes.

The growing population demands and environmental concerns associated with traditional protein sources have prompted the exploration of alternative and sustainable food sources. The purpose of this comprehensive review is to highlight the nutritional benefits and sustainability of insect-based foods as a promising solution. Global population growth necessitates innovative approaches to meet the demand for nutritious and sustainable protein sources. There are numerous challenges associated with traditional livestock farming, including land use inefficiency, high water usage, and greenhouse gas emissions. As a result, edible insects have emerged as a viable alternative, providing proteins (35-77% of dry matter), healthy fats (10-50%), essential amino acids, and micronutrients such as iron (up to 31mg/100g) and zinc (up to 20mg/100g), vitamins, and minerals. In contrast to livestock, which requires 22,000-43,000 liters of water to produce 1 kg of beef, insect farming consumes significantly less water and land resources. Insects have the potential to address nutritional deficiencies and strengthen food security as they are recognized for sustainable production. The study thoroughly investigates the literature addressing environmental and sustainability concerns associated with edible insect farming, using a rigorous bibliometric and scientometric analysis via Vos viewer. With the help of Vos Viewer, it was possible to identify the geographical distribution of countries that contributed to the field of edible insects and their acceptance, as well as the top ten documents in this field with the most citations and mostly used keywords in this field of research. Future research and implementation strategies will be able to benefit global food security and environmental conservation through these alternative protein sources.

Background Malnutrition is a significant public health issue in Bangladesh, particularly impacting women and children. Rajshahi, marked by socio-economic disparities, offers a distinctive context to explore the nutritional status and health outcomes of these vulnerable groups. Objectives This study aims to assess the nutritional status of women and children in Rajshahi and investigate associated health outcomes. Additionally, it seeks to identify socio-economic and cultural factors that influence nutrition. Methods A mixed-methods approach was utilized, incorporating a cross-sectional survey of 460 households and in-depth interviews with mothers and caregivers. Anthropometric measurements were taken to evaluate the nutritional status of women and children, while dietary assessments measured nutrient intake and diversity. Logistic regression analysis was performed to determine the likelihood of malnutrition based on socio-economic characteristics, thereby identifying key risk factors. Results The findings indicate a troubling prevalence of malnutrition, with 36% of children under five classified as stunted and 25% as underweight. The analysis highlights critical factors contributing to chronic undernutrition, including maternal education, employment, and dietary diversity. Notably, mothers aged 27-37 exhibit a lower risk of undernutrition, and urban households with secure food access demonstrate better nutritional outcomes. Discussion Maternal education and employment were positively associated with better nutritional outcomes, as educated and employed mothers had higher chances of maintaining a normal BMI. Regular ANC visits (≥4 visits) were crucial for improved maternal nutrition. Household food security emerged as a significant determinant, with food-secure households showing better maternal nutritional status. Safe water access and adequate dietary diversity were also linked to improved maternal BMI. Additionally, factors such as child birth weight, exclusive breastfeeding, and childhood diarrhea significantly influenced maternal nutrition. Moreover, frequent antenatal care visits and a diverse diet are vital in mitigating undernutrition risks among children. Conclusion This study emphasizes the urgent need for targeted interventions to combat malnutrition in Rajshahi. Recommendations include implementing community-based nutrition education programs and improving access to healthcare services. By addressing the socio-economic and cultural determinants of nutrition, stakeholders can enhance health outcomes for women and children in the region, ultimately contributing to broader public health objectives in Bangladesh.

Enset (Ensete ventricosum) is a vital food security crop cultivated in South and South-western parts of Ethiopia. However, enset production and the farming families have been threatened by Xanthomonas wilt and its spread in the farming system. Thus, this study was conducted to investigate the soil fertility and plant management practices association on the incidence of Enset Xanthomonas wilt. Data on soils fertility and diseases from enset based farming clustered into inner, outer and outfield farm zone were sampled and surveyed. The result indicated that soil chemical properties significantly (p≤0.05) varied from inner to outfield farm zone. Significantly maximum nutrients store revealed in inner enset farm zones. Disease incidence reduced from inner to the outfield enset farm zone. Disease prevalence and disease incidence scored 28.5% and 11.6%, respectively depending on altitude and genotypes. Soil fertility levels in the enset inner and outfield plots were varied purposely to cultivate enset products as kocho, bulla or amicho (cooking type). The variations in soil fertility and Xanthomonas wilt incidence was associated with management practices applied for desired enset products. Therefore, management practices in enset based farming, soil fertility and location of enset planting zones found to be major indicators for disease incidence addressing to device control interventions.

Camels are a significant source of income for nomadic populations in many developing countries, including Ethiopia. Camels are well adapted to dry and semi-dry regions, providing income, food security, and transportation. However, camel production and productivity are constrained by infectious diseases, such as brucellosis, which is a highly infectious bacterial disease that affects camels and humans worldwide. Brucellosis causes significant economic losses due to abortion, low herd fertility, and decreased milk production. In Ethiopia, the prevalence of camel brucellosis varies depending on factors related to the host, agent, climate, and management system, with a reported prevalence ranging from 0.5% to 11.9%. Accurate diagnosis of camel Brucellosis is essential for herd-based screening of animals. Although culturing the pathogen is the preferred method for diagnosis, serological tests such as Rose-Bengal plate test (RBPT), Enzyme-linked immunosorbent assay (ELISA), and Complement fixation test (CFT) and polymerase chain reaction (PCR) assays have been developed. Implementing effective diagnosis and surveillance systems to control the spread of brucellosis in animals and humans is very important, on top of awareness campaigns, vaccination programs, and suitable laboratory establishment recommended. Continued research is essential to maintain the health and productivity of camel populations, particularly in pastoral areas where camels play a significant role in the livelihood of communities. Therefore, the present paper views the seropositive prevalence and potential risk factors associated with camel brucellosis in Ethiopia.

In India, loss of fertility through soil erosion is primarily a summer monsoons mediated phenomenon. Reversing the land degradation processes contribute to water availability, soil fertility maintenance, adapting to climate change and overall food security. Whereas kharif (monsoon/rainy season crop) foodgrain production largely depends on summer monsoons, the rabi season (post-rainy season/winter crop) rainfall is too little to exert a direct influence. In spite of larger acreage under kharif foodgrain crops, total fertiliser consumption during kharif and rabi seasons is comparable. Negative rainfall anomalies (deficit) adversely affected total fertiliser consumption and their use efficiency. Despite significant differences in fertiliser application rates, the response to applied fertiliser nutrients is almost similar in the two seasons. This implies that nutrient use efficiency (NUE) has a ‘manageable’ and an ‘unmanageable’ component wherein 4R practices are difficult to implement under unfavourable kharif weather conditions. Partial factor productivity of fertilizer nutrients (PFPF) has continuously declined over decades mainly because of depletion of soil organic carbon, imbalanced use of nutrients and inability to maintain soil moisture supplies. These observations plus yield-gap analysis permitted us to conclude that past trends of declining NUE can only be reversed through a shift either in sustainable land management practices or enhancing the genetic yield potential/ biomass of crop cultivars or by combining both and making kharif crop planting independent of monsoons rains through direct dry seeding.

For economic growth and development in any WE African country the GDP progress is depending on the key push-pull factors as migration, personal remittances received, bilateral aids and, absolutely, employment in agriculture which is about 1/3 of the population and not a predominant and protected minority as happens in the industrialized EU and North America. In order to represent the framework of the reciprocal dependencies the present study used the statistics of Gambia from WDI covering the periods from 1960 to 2017 by applying linear regression models. The results confirmed that migration and remittances have significant positive impact on employment in agriculture because new investment in agriculture created new skilled and unskilled employment. The results also found out that employment in agriculture has negative and significant impacts on foreign aids: 10% increase in migration, increases foreign aid by 50.3%. Increasing 10% of remittance, increase economic growth by 0.14% but 10% increases in employment in agriculture, decrease economic growth by 0.04%. To face globalization the economy of the Gambia should use the foreign aid to improve agriculture production and productivity thereby increase economic growth through human capital theory of migration, skilled migration, export and food security, the study recommends.

Aim This cross-sectional study assessed the nutritional status of ethnic reproductive women aged between 15-40 years, comprising 85 lactating women (LW) and 86 non-pregnant-non-lactating women (NPNLW) who lived in various parts of three hilly districts (Bandarban, Khagrachari and Rangamati) of the Chittagong Hill Tracts (CHTs) of Bangladesh. Materials and Method Research tool was pretested semi-structured questionnaire for this observational study. Anthropometric indices like weight, height and mid-upper-arm-circumference (MUAC) were used in assessing the nutritional status. Results Most (44.4%) of the ethnic women were Marma, followed by Chakma (39.8%), Bam (8.2%) and Tripura (5.8%). No significant (P>0.05) differences were observed in socio-economic variables between LW and NPNLW. Overall, mean age of the women was 28 (±7.2) years; mean family income was 18,822.2 (±3091) BDT and majority (86%-87%) were reported to be food secured throughout the year. Mean Dietary calorie (2631±798 kcal) intake of both groups were up to the mark according to the recommended dietary allowances (RDAs) and most (80.3%-86%) of them also possessed good nutritional knowledge. However, no significant (P>0.05) differences were observed in dietary calorie intake and nutritional knowledge score between two groups of women. Overall, most (68.4%) of the women had normal body max index (BMI kg/m2), 11.7% were found to be undernourished or thin and 19.9% were overweight. It was noticed that better nutritional status of LW and NPNLW were significantly associated with literacy (P<0.05), occupancy in household chores (P<0.05), better income (P<0.05), food security (P<0.05), recommended calorie intake level (P<0.05) and better nutritional knowledge score (P<0.05). Conclusion This study showed that vast majority of the ethnic reproductive women of CHTs are in better nutritional status with normal BMI (kg/m2) and daily calorie intake according to RDA. Most of them were food secured and their nutritional knowledge score was also up to the mark. Better socio-economic condition, nutritional knowledge and accurate calorie intake play a vital role in achieving healthy nutritional status of the two women groups of CHTs.

The incidence of gastrointestinal parasites in Zebu and N’dama breeds known to be trypanotolerant cattle from some ranches in Jos Plateau was investigated at the peak of the raining season, August to October, 2018. A total of 150 cattle from some Ranches in Jos Plateau were randomly selected for faecal sampling out of which 85 were Zebu (Bos indicus) and 65 were N’dama (Bos taurus) breeds respectively. The samples were analyzed for ova of gastrointestinal parasites using the simple flotation and sedimentation techniques and the results were interesting. The strongyloids, Oesophagostomumradiatum had the highest incidence of 4.7% followed by the Trichostrongylus species with 4%. Fasciolagigantica and Haemonchusplacei both were 3.3%. Then Paramphistomumcervi 2%; bovine hook worm, Bunostomumphlebotomum 1.3%, Taenia saginata1.3%, Schistosoma bovis 1.3% and Nematodirusspathiger 0.7%. The incidence of nematodes, cestodes and trematodes in this study in the raining season was significant (p<0.05) and could pose production and economic threat to institutional farms and ranches in the development of livestock and dairy industries in Nigeria. There should be a strong policy on the control of gastrointestinal parasites in the country for farmers to benefit from their contribution in ensuring food security.

The importance of horticulture around the large cities, called green belt (GB), or proximity food production area is related to its contribution to the provision of food as well as its role on social, cultural and ecological aspects. Geoscience and Remote sensing (GRS) are tools that should aid in gathering and updating the information to develop science-based management plans of this areas. Recently, the improvement in terms of spatial, temporal and radiometric resolutions has changed the performance and the approach to the horticulture remote sensing. In this work, we make a brief review on the literature exploring the use of GRS techniques in horticulture, and future trends in order to exploit the available techniques for efficient crop management in the way to improve territorial planning and management. Specifically we found a lack of academic production in this area. In addition we examine the importance of this landscape areas from different points of view (food security, health, ecology, etc.). A systematic revision of published studies on remote sensing on horticulture including different platforms, sensors and methodologies are briefly presented. Finally some aspect related with future trends are discussed.

This study reviews the agricultural development perspective in the light of a rapid space technology development. In other words, precision agriculture as part of geoinformatics. The aim is to quantify whether the adopted technology can improve the efficiency of agricultural fields management and production to attain food security. Therefore, views of targeted groups from different States of Sudan were investigated, using stratified sampling method. Where quantitative statistics (descriptive/inductive techniques) was applied. About 800 questionnaires were distributed. The outcomes of data analysis reflected that the majority of interviewed groups 357 (82.1%) do not know the principles and application of integrated technology in the field of agricultural management. 85.3% of respondents know nothing about computer program related to precision agriculture. The majority of the respondents (84.6 %), did not get courses on precision agriculture during the under graduate study. The result also revealed that only 11.8% of the respondents use modern techniques in land preparation, 16.1 % in soil analysis, 12.5 % in the field of seed technology, and 11.4% in crop harvesting. However, 53.9% of the respondents reported that their Departments did not care about training on agricultural precision. Nevertheless, 24.3 % of the respondents got trained on precision agriculture through personal efforts, while about 19% got trained by their respective Departments. In regard to education, 16% of the respondents got trained on precision agriculture at undergraduate and only 9% after graduation. The study concludes that despite the rapid technological development, agriculture in Sudan remained lagging, and the productivity is below the expectation. It recommends that the Ministries of Agriculture in different States in Sudan should take the issue of introduction of new technology seriously to boost the agricultural development to attain food security.
