Integrating indigenous knowledge system in extension education: The potential for sustainable agricultural development in Nigeria
(Apex Journal International, 2013) Anaeto, F. C.; Asiabaka, C. C.; Nnadi, F. N.; Aja, O. O.; , Ajaero, J. O.; Ukpongson, M. A.; Ugwoke, F. O.
This paper looks at the integration of indigenous knowledge system in Extension education with the aim of promoting sustainable agricultural development. It explores the meaning of indigenous knowledge and extension education. Attempts made in the past to achieve agricultural development, provide rationale to valuing indigenous knowledge and integrating indigenous knowledge in extension education. Efforts have been made in the past in pursuit of agricultural development but few of those involved in these effort including those in extension services take the trouble to understand the farmers and their indigenous knowledge rather the farmers are often described in generalization as ultra –conservative, steeped in tradition, hemmed in by custom, lacking in motivation and inactive, captive to age-old methods, incapable of making wise decisions. There have however, been a growing consensus now that some of the solutions to the problems that currently plague agricultural development must proceed from the role of understanding the dynamics within the local context and local capacities. Such dynamics include the roles of indigenous knowledge and practice in sustainable agricultural development. This can be achieved by integrating indigenous knowledge into the extension education system to address some of the knowledge deficiencies for development that is currently formulated from the western perspective. There is therefore a need for paradigm shift towards harnessing indigenous knowledge for the development of extension service since sustainable agriculture in all nations will require greater scientific respect for and more effective collaboration with those who possess the wisdom of generations of non scientific farming. It is in the face of this that indigenous knowledge becomes handy especially in its ability to promote sustainable agricultural development.

Rural farm-households perception of land-related conflicts as an impediment to rural livelihoods in Imo State, Nigeria
(Academia Publishing, 2018) Chikaire, J. U.; Nnadi, F. N.; Ajaero, J. O.; Ogueri, E. I.
The aim of this was to establish whether or not land-related conflicts could be detrimental to the lives and survival of rural people in Imo State. The specific objectives were to identify livelihood strategies of the respondents, examine perceived causes of conflicts in the area; ascertain effects of conflicts on rural economy/livelihood of the respondents and determine measures to reduce conflicts in the study area. Purposive random sampling technique was used to select 300 respondents from conflicts affected areas in Imo State. Data were collected with structured questionnaire and oral discussion with the respondents. Data were analyzed using percentages and mean to achieve the objectives of the study. The results showed that 100% of the respondents engaged in farming for survival. The major causes of the conflicts were human population pressure (M=3.43), encroachment without permission (M= 3.30), land tenure system (M=3.45), among others. The major effects of conflicts on rural economy and livelihood were farmland abandonment (M = 3.37), decrease income (M=3.12), reduction in yield (M=3.31), loss of lives (M=3.60), insecurity(M=3.00), increased hunger and starvation ( M=3.47) among others. To curb conflicts, security be provided to the communities, settlement of dispute be done quickly, and educating all actors would be necessary.

Use of information and communication technology (ICT) tools for mitigating land conflicts in Delta State, Nigeria
(SAAT FUTO, 2021) Ajaero, Joseph Onyewuchi
The study investigated the utilization of ICT tools for mitigating land conflicts in Delta State, Nigeria. Data were collected with structured questionnaire distributed to 120 respondents who were randomly selected. Percentage and mean were used to statistically analyze data. It was found that the following possible ICT devices/tools could be used in the area; computer (99.2%), internet (94.2%), maps/survey plans (89.2%) and internal data capture system (71.7%). Several factors causing land conflicts were double allocation of land (𝑋̅=3.60), inefficiency in delivering land service (𝑋̅=3.55), family boundary disputes (𝑋̅=3.53), corruption/ greed (𝑋̅=3.49), inappropriate use of technology to register lands, (𝑋̅=3.39), inappropriate land tenure systems (𝑋̅=3.27) and communal boundary disputes. It was observed that ICT has a significant role in mitigating land conflicts. The ICT role in land conflicts management is felt in the areas of facilitating easy planning and management, increased awareness on land issues and it ensures security on land tenure system The use of geographical information system (GIS) should be introduced by government to support spatial analysis and visualization, including a map based interface for web information services. Government should introduce Land Information System (LIS) to the land offices at local level to improve efficiency in delivering land services.

Extension and advisory services roles in creating resilient value chain of smallholder rural farmers in Imo State, Nigeria
(U. P., 2019) Chikezie, N. P.; Ajaero, J. O.; Akande, S. N.; Chikaire, J. U.
Smallholder farmers are most affected by climate change shocks and weather related disasters the world over, and they are also vulnerable to market fluctuations and poor governance, conflicts and even diseases. Extension and advisory services provide an opportunity for strengthening resilience of rural farming households by increasing their access to both material and non material resources. This paper sought to explain how Extension Services Providers build resilience of rural farmers in Imo State, Nigeria. The researcher selected 120 Extension workers and 230 rural farmers for interview. Questionnaire was given to both respondents, and complimented by oral discussion. Data collected were analyzed descriptively. With a discriminating mean (M) score of 2.0, it was seen that climate change affects the farmers adversely. Climate change damages crops in farm and field (M=2.50), reduced quality/quality of crops(M=2.45), leads to sudden death of crops(M=2.70) among others. To build resilience of rural farmers, extension workers promoted the following resilient approaches - diversification of income sources (M=2.81), market information provisioning (M=2.79), behavioural change campaigns(M=2.54), crop diversification (M=2.67), among many others. The farmers face the challenge of insufficient incomes, poor monitoring, low understanding of climate change, resilient options etc.

Rural energy needs of smallholder women farmers for improved farm productivity and rural business enterprises in Abia State, Nigeria
(Kosmos Publishers, 2020-12-11) Godson-Ibeji, C. C.; Chikaire, J. U.; Ajaero, J. O.; Markalbert, U. S.
The study investigated the energy needed by rural women farmers to improve their livelihood and agricultural production in Abia state. The specific objectives were to identify the energy needs, identify energy needs rural business enterprises; and to identify the energy sources available to the respondents in the study area; identify the effects of access to energy on women farmers,. A purposive sampling technique was adopted in selecting 150 respondents. Data were collected by use of structured questionnaire and interview schedule. Simple descriptive statistics such as mean, percentage and frequency distribution and a 4-scale Likert type scale were used to analyze the data. The result revealed that women in the study area need energy for many activities, both on farm and off farm and some of the areas include cooking, processing, storing, telecommunication, infrastructure and transportation and others. Increased productivity, high income generation, reduced stress, increased living conditions are some of the effects of access to energy have on rural women farmers. The women in the area have few energy sources on which they depend on to carry out their various activities and these sources include machines, electricity and human power. Based on the findings, recommendations were made on women being seen as great movers of agricultural production and should be allowed and assisted to have better access to energy sources just like their male counterparts.

Status of institutional arrangements for managing resource use conflicts among crop farmers and pastoralists in Imo State, Nigeria
(Juniper Publisher, 2018-12-10) Chikaire, J. U.; Ajaero, J. O.; Ibe, M. N.; Orusha, J. O.; Onogu, B.
This study ascertained the institutions put in place to manage conflicts between crop farmers and pastoralists in Imo State, Nigeria. Specifically, the study aimed to achieve the following objectives; to identify the institutions saddled with the responsibility of managing conflicts in the study area; determine strategies used by the institutions in managing conflicts in the area; and to ascertain factors hindering the management of conflicts between crop farmers and pastoralists. Data were collected with structured questionnaire, complimented with observation and oral interview from 300 crop farmers and 40 nomads. The data were analyzed using descriptive statistical tools such as mean and standard deviations. The results showed that traditional rulers (M=2.90 for crop farmers and 2.37 for pastoralists), town unions/Miyetti-Allah (M=2.11 crop farmers and M=2.52 for the pastoralists) were efficient in managing conflicts. The strategies employed in resolving conflicts include setting up of community committees for peaceful resolution of conflict issues and use of dialogue, accommodation of the other party. On and off nature of the pastoralists, lack of fund, corruption, distrust were factors that work against conflict resolution. The government should give the institutions mentioned earlier more powers in handling conflict issues and locate the nomads permanently at a place.

Relevance of indigenous knowledge in weather and climate forecast for planning farm activities by farmers in Imo State, Nigeria
(Juniper Publishers, 2018-12-17) Chikaire, J. U.; Ajaero, J. O.; Ibe, M. N.; Orusha, J. O.; Onogu, B.
The study assessed the relevance of Indigenous Knowledge (IK) on weather and climate forecasting for planning farm activities by farmers in Southeast, Nigeria. Questionnaire was used to elicit information from a total of 360 farmers, complement with oral interview. Mean (M) was used to analyze data. Results showed that IK indicators commonly used for weather and climate forecasting fall into 3 categories namely trees, animals and atmospheric indicators. The IK indicators used to predict the dry season and harmattan were-fruits drying/falling off from trees, increase occurrence of termites, shedding of tree (M=2.40), appearance of rainbows (M=2.53) among others. The indicators for onset of the rains included flowering of trees (M=304), heavy budding of acacia tree species (M=300), dormancy breaking in certain tree/fruit species, Others were appearances of large number of ants, frequent sounds of frogs, appearance of ant hill, appearance of millipedes, appearances of army worms, dark clouds appearance, body feels heat at night, increased body pain, mist covering hilly areas among other signs. As a recommendation, the knowledge of indigenous peoples should be included when designing climate change adaptation strategies in SSA.

Renewable energy for sustainable food, feed and fibre production: A Panacea to Nigeria’s energy crisis
(U. P., 2011) Nnadi, F. N.; Chikaire, J.; Ajaero, J. O.; Nwakwasi, R. N.; Oguegbuchulam, M. N.
Agriculture is the sole provider of human food. Most farm machines are driven by fossil fuels, which contribute to green house gas emission and, in turn, accelerate climate change. Such environmental damage can be mitigated by the promotion of renewable resources such as solar, wind, biomass, tidal, geo-thermal small-scale hydro, biofuels and wave-generated power. This is because, energy inputs are critical to agricultural production and long-term sustainability of global agricultural production will require renewable alternative energy resources. There are many systems that can provide on-farm energy resources from renewable sources. Solar energy, wind and small scale hydro systems can provide on-farm as well off-farm energy resources. These renewable resources have a huge potential for the agriculture industry. The concepts of sustainable food, fibre and feed production lies on a dedicate balance of maximizing productivity and maintaining economic stability, while minimizing the utilization of finite natural resources and detrimental environmental impacts. It also emphasize replenishing the soil for future use. Hence, there is a need for promoting use of renewable energy systems for sustainable food production, for instance, solar photovoltaic water pumps and electricity, greenhouse technologies, solar dryers for post-harvest processing, and solar hot water heaters and so on. This article thus explains in detail the role of renewable energy in farming for production of safe and secure food for humans.

Productivity of yam-cassava based/land-race legumes in inter-cropping systems
(2008) Ibeawuchi, I. I.; Obiefuna, J. C.; Ofoh, M. C.; Matthews-Njoku, Edna; Ajaero, J. O.
Raising and sustaining the productivity of smallholder tuber based crop mixture is the major problem facing tropical agriculture. This problem is connected with the development of low input technologies, which is the sure and noble alternative of which the tuber/land race legume mixture is the answer. However, the more the component crops in the mixtures the lower, the individual crop yields. Crop mixtures involving lima bean and African yam bean were most efficient judged by the higher LER and gave the highest monetary returns which is the satisfaction of the smallholders farmer who produce majority of our foods.

Women farmers preferred communal land conflict management and resolution strategies in Abia State, Nigeria
(U. P., 2019-05-17) Ogueri, E. I.; Chikaire, J. U.; Ajaero, J. O.; Ibe, M. N.
Communal land conflicts affect have become common in Nigeria among different users of land especially farmers. This study examined women farmers’ preferred land conflict management and resolution strategies in Abia State, Nigeria. The specific objectives were to identify the perceived causes of communal land conflicts; determine the preferred institutions for resolving land conflicts; examine the perceived effects of communal land conflicts; identify the respondents’ preferred conflict resolution strategies used; and the reasons for preference of the strategies used. Data were collected using questionnaire and oral interview and analyzed with mean and standard deviation. Results showed that claim of ownership with mean (M) value of 2.70, indiscriminate grazing by animals (M=2.60), population pressure (M=2.54), contested boundary (M=2.51) were major causes of land conflicts. The institution preferred for conflict resolutions were amala (M=2.53), umuada (M=2.93), town unions/age grade (M=2.48) and agbara (dieties) (M=2.74). Conflict leads to low productivity (M=2.37), loss of lives and property (M=2.64). The women prefer mediation, reconciliation, compromise and accommodation for resolving conflicts and the reason being that problems are solved one at a time, leads to a win-win situation, lowers level of tension, creation of goodwill among others.

Climate change adaptation needs/priorities of rural woman farmers in flood plain areas of Owerri agricultural zone of Imo State, Nigeria
(Jomard Publishing, 2017) Chikaire, J. U.; Anaeto, F. C.; Ajaero, J. O.; Godson-Ibeji, C. C.
Adaptation is key to surviving the menace of climate change. This paper investigates adaptation needs/priorities of rural women farmers in Imo State, Nigeria. The specific objectives were to ascertain rural women farmers awareness of climate change, identify perceived effects of climate change on rural women farmers, examine adaptation needs of these women and determine adaptation strategies used by rural women. Data were collected with structured questionnaire from 180 rural women farmers randomly selected from a list of 1800 registered women farmers with the Owerri ADP office. Results showed that the rural women were very much aware of climate change as indicated by high mean responses to certain signs such as increase in temperature. (M = 2.31), unpredictable heavy rainfall (M = 2.51), unpredictable heavy winds (M = 2.45) among others. Climate change affects rural women by increasing their work load, reducing their food portions, loss of farm assets, increase rate of diseases/illness. In adapting to climate change, the rural women farmers need as a matter of urgency to find alternative livelihood options (M = 2.68), safer areas to relocate (M = 3.31), access to credits/market (M = 3.34) among others. To adapt, they employ strategies such as crop rotation, planting early maturing crops, engage in off-farm activities, cooperative farming.

Effects of resource-use conflicts on rural women farmers in south–east agroecological zone of Nigeria
(Academia Publishing, 2018-11) Chikaire, Jonadab Ubochioma; Ajaero, Joseph Onyewuchi
This study analyzed specifically the effects of resource-use conflict especially, land on rural women farmers in Southeast, Nigeria. A total of 300 rural women farmers were purposively selected from 3 states in southeast where conflicts have occurred. Data collected were analyzed descriptively – using percentages, mean and standard deviation. Results obtained showed that farmer-farmer conflicts, pastoralists – farmer conflicts and communal conflicts were predominant in the study area with 100% response. The major causes of resource use conflicts were increasing population (M = 3.37), overgrazing of farmland (M =3.35), breakdown of moral economy (M=3.57), pollution of water (M=3.46), among others. The effects on women included reduced crop yields (M=3.37), burning of crops (M= 3.38), reduced farm, reduced income (M=3.01), loss of human lives (M = 3.56), rape/abduction of women (M = 3.00), hatred (M = 2.63), fear (M = 2.57), widowhood (M = 2.93) among others. The following strategies were identified, giving financial assistance to victims (M = 2.65), creating job opportunities (M = 2.53), proper land use planning (M = 2.63), and compensation to land owner (M = 3.67). These farmers could be helped by providing credit facilities and proper land use planning programme.

Effects of crop farmers / pastoralists conflicts on sustainable livelihood assets and strategies of displaced farmers in Imo State, Nigeria
(U. P., 2019) Ogueri, E. I.; Chikaire, J. U.; Ibe, M. N.; Ajaero, J. O.
One of the effects of crop farmers/pastoralists conflicts is displacement of the farming population the world over, Nigeria not exceptional. This work investigates the effects of conflicts on livelihood strategies and assets of displaced farmers in Imo state. A total of 300 crop farmers was selected randomly from the affected communities. Questionnaire complimented with oral discussion were used to elicit information from the respondents. Data collected were analyzed using percentage, mean and standard deviation presented in tables. Results showed that major livelihood strategies of the crop farmers were farming with 100 percent response, followed by wage labour (94.6%), sales of wild fruits (70%) and migration of work labour outside the community (73.3%). Conflicts affect livelihood strategies by restriction of movement which prevents farmers from moving and risks to personal safety (72.3%). Conflicts affect all the five livelihood assets beginning with the social assets by its disruption of community life (M=2.79), collapse of local authority (M=3.40), disruption of family goals/life (M=2.50) among others. On the human assets, conflicts leads to death of laborers /farmer workers (M=3.32), sexual harassment (M=2.56), separation of family members (M=2.45). The physical assets affected included disruption of health services and infrastructures, closure of schools, looting of possessions among others, while the financial and natural assets affected included destruction of crops and animals, market closure, destruction of water wells, contamination of water, and low abandoned and limited asset to farm.

Displaced farmers perception of resource-use conflicts as an obstacle to household food security and food safety in Abia State, Nigeria
(U. P., 2019) Chikezie, N. P.; Ajaero, J. O.; Akande, S. N.; Chikaire, J. U.
Conflicts occasioned by different land users have become common place now. When farmers are displaced from their ancestral home due to conflicts involving pastoralists, life becomes difficult and unbearable. This paper investigates displaced farmers perception of resource use conflicts as an obstacle to household food security and food safety. A total of 300 displaced farmers were selected for interview and data obtained were analyzed using mean and standard deviation. Result showed that conflicts create food shortage (M=3.43), destroys food stocks (M=3.57), disrupts production processes (M=3.28), reduced farm investment (M=3.19), among others. Again, during conflict situation, food items are easily contaminated with mean score of 3.27, foods are handled with dirty hands (M=2.58), unsafe water could be used to prepare food (M=3.31), outbreak of food borne illness (M=2.92), poor quality of food eaten (M=3.31), among other reasons. It is recommended that adequate food be supplied to the displaced farmers in the form of aid, water supply be provided to displaced farmers and health facilities put in place to handle case of illness and to avoid spread of illnesses.

Discriminant functions for classifying erosion degraded lands at Otamiri, Southeastern Nigeria
(U. P., 2002) Oti, N. N.
This study was conducted to evaluate the effect of natural in-situ erosion on soil physico-chemical properties and to identify indicator variables associated with various degrees of erosion on a Southern Nigeria Ultisol. A preliminary survey conducted in 1997 had delineated four erosion phases on a contiguous sloping land within a watershed The erosion classes were Non-eroded (NE), Slight (S), Moderate (M) and Severely eroded (Sv) based primarily on Ap horizon thickness. Field experiments and laboratory analysis were done in/998/99. Definite consistent relationships that were statistically significant were observed between erosion class and some soil physical and chemical properties of surface 0–10 cm layer: Among these were silt/clay ratio which ranged from 0.29 in NE to 0.19 in Sv; fine sand/coarse sand ratio were 0.33 (NE), 0.31 (S), 0.17 (M) and 0.19 (SV). Soil organic carbon (SOC) declined from 1.01% in NE to 0.60% in Sw, and (Ca+ Mg)/(Al+ H) ratio, used to infer nutrient imbalance, also decline from 1.23 in ME to 0.43 in Sv. Aluminum saturation percentage increased from 33% in NE to 60% in Sw, and Ca/Mg ratio from I. 14 (NE) to 1.62 (Sv). Pedo transfer functions suggested that erosion–induced soil alterations are more process based than simple factor dependent. It is therefore recommended that in this environment the prediction of erosion hazard and the identification of erosion classes be based on discriminant analysis derived from silt/clay, fine sand/coarse sand, Ca/Mg, and (Ca+ Mg)/(Al+ H) ratios. Soil organic carbon and Al""" saturation are equally important indicator variables.

Effects of potassium (K) sources and rates on tuber yield and storage life of white yam (dioscorea rotundata poir) grown in an ultisol of Southeastern Nigeria
(U. P., 2014) Okonkwo, B. C. N.; Oti, N. N.; Okore, I. K.
The effect of potassium (K) sources at two rates on tuber yield and storage life of white yam was investigated. The four sources of potassium were; defatted palm kernel cake (DPKC), poultry manure (PM), their combination (DPKC+PM) as organic K source and combined NPK fertilizer as inorganic K source while the two rates were 37.5 and 75.0kg K tha-1 (low and high rates) based on their K content and a control (no application). These treatments were laid out in a randomized complete block design (RCBD) with four replications and the test crop was a local land race (Nwopoko). Planting was in April (on-set of rain) while harvesting was done at seven months after planting (November) in both 2010 and 2011. Healthy tubers of varying grades were selected from each treatment for storage studies over a period of six months. While in storage, the tubers were examined periodically for weight loss, rot incidence, sprout development and dormancy period. Tuber yields and storage data were subjected to analysis of variance. Two years (2010/11) mean indicated that among K source, poultry manure at high rate showed significant difference to the control and had 41.67, 20.48, 24.50 and 28.84% increases over combined NPK fertilizer at similar rate on number large (>1kg), small (<1kg), total number and total tuber weight respectively. Utilization efficiency test further buttressed the superiority of K sources at both rates over the control. Tubers from defatted palm kernel cake plots enhanced the storage life of the white yam tuber by recording the least loss in weight, rot incidence and sprout weight of 27.00, 9.40 and 4.75% respectively, and the longest dormancy period of 95.5 days. From the result, it can be concluded that K sources at high rate proved more effective than low rate. Poultry manure had significant increase over the control and combined NPK fertilizer in the tuber yield attributes. Defatted palm kernel cake enhanced the storage life of the white yam tuber significantly (P=0.05).
