Settlement history of a mountain oasis in Northern Oman
(2004)
To unravel the settlement history of oases in northern Oman, data on topography, the agricultural setting, water and soil parameters and archaeological findings were collected in the Wadi Bani Awf with its head oasis Balad Seet. Data collection lasted from April 2000 to April 2003 and was based on the establishment of a 3D-georeferenced map of the oasis comprising all its major infrastructural and agronomic features. At today's Balad Seet, a total of 8.8 ha are planted to 2,800 date palms and 4.6 ha are divided into ...

Organic inputs and farmers' management strategies in millet fields of western Niger
(2004)
Research on soil fertility management in sub-Saharan Africa was criticized lately for largely ignoring farmers’ management strategies and the underlying principles. To fill this gap of knowledge, detailed interviews were conducted with 108 farm households about their rationale in managing the soil fertility of 307 individual fields in the agro-pastoral village territory of Chikal in western Niger. To amplify the farmers’ information on manuring and corralling practices, repeated measurements of applied amounts of ...

Ensuring community and agricultural resiliency to climate change: Ceremonial practices as emic adaptive strategies
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2016-12-23)
This paper is an analysis of emic versus etic approaches to climate change resiliency, taking as a case study the traditional ceremony performed by farmers in eastern Flores, Indonesia to rid their fields of rats. This paper begins by providing a theoretical framework discussion on the dominant etic and emic academic research on monsoons and climate change impacts on agriculture. The rat ceremony performed in villages throughout East Flores is a local custom used to rid agricultural fields of pests—often rats—that ...

Nutrient cycling and field-based partial nutrient balances in two mountain oases of Oman
(2005)
Little is known about nutrient fluxes as a criterion to assess the sustainability of traditional irrigation agriculture in eastern Arabia. In this study GIS-based field research on terraced cropland and groves of date palm (Phoenix dactylifera L.) was conducted over 2 years in two mountain oases of northern Oman to determine their role as hypothesized sinks for nitrogen (N), phosphorus (P) and potassium (K). At Balad Seet 55% of the 385 fields received annual inputs of 100–500 kg N ha^-1 and 26% received 500–1400 kg ...

Vegetation changes in a river oasis on the southern rim of the Taklamakan Desert in China between 1956 and 2000
(2003-11-26)
The indigenous vegetation surrounding the river oases on the southern rim of the Taklamakan Desert has drastically diminished due to overexploitation as a source of fodder, timber and fuel for the human population. The change in the spatial extent of landscape forms and vegetation types around the Qira oasis was analyzed by comparing SPOT satellite images from 1998 with aerial photographs from 1956. The analysis was supplemented by field surveys in 1999 and 2000. The study is part of a joint Chinese-European project ...

Comparison of linear discriminant analysis, support vector machine and artificial neural network in classifying Nigerian local turkeys based on plumage colours using biometric traits
(2022-10-18)
The ability of linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural network (ANN) models to differentiate biometric traits of Nigerian local turkeys was investigated in this study. The biometric traits (bodyweight, body length, breast girth, thigh length, shank length, keel length, wing length, and wingspan) in 200 (20-week-old) turkeys were measured. Seventy percent of the datasets were used to train the three models, with the remaining 30% being used to test their performance. All ...

Use of corncob biochar and urea for pakchoi (Brassica rapa L.) cultivation: Short-term impact of pyrolysis temperature and fertiliser dose on plant growth and yield
(2022-10-18)
This study aimed to evaluate the effect of pyrolysis temperature of corncob biochar as a soil amendment and urea fertiliser on the growth and yield of pakchoi. Pakchoi was cultivated in pots
(13 cm height, 19 cm upper diameter, and 13.5 cm bottom diameter). Two factors including pyrolysis temperature of biochar and urea dose were combined with four levels each. Pyrolysis temperature factor consisted of B0 (no biochar), B1 (250 °C), B2 (300 °C), and B3 (350 °C). Urea dose consisted of F0 (no urea), F1 (0.6 g pot-¹), ...

Agripreneurial drive among women shea butter processors in Kwara State, Nigeria: the motivating factors and efficiency
(2022-10-12)
This study examined agricultural entrepreneurship among women shea butter processors in Kwara State Nigeria. It assessed their motivation factors, level of efficiencies, determinants of output and challenges faced in the entrepreneurial drive by the women. Primary data, collected using a semi-structured questionnaire, were collected from randomly selected 120 shea butter women processors. The data obtained were analysed with descriptive statistics, index ranking and the stochastic frontier function. The results showed ...

Understanding the emergence and evolution of pastoral community groups from the perspective of community members and external development actors in northern Kenya
(Kassel University Press, 2019-01-15)
Whereas there is abundance of information on community groups that engage in income generation in rural agricultural and peri-urban areas, information on community groups in pastoral areas still remains scarce. However, in the recent past, a growing trend of such groups has been observed in the pastoral areas in northern Kenya. This study therefore explores how these groups have emerged since Kenya’s independence in 1963 to date, and which factors have contributed to their evolution. A full survey on all income-generating ...

Effect of Village Savings and Loan Associations on adoption of index-based crop insurance under limited liabilities
(2020-03-26)
A household survey and focus group discussions were conducted to quantify the general determinants of an index-based crop insurance adoption under limited liabilities in Burundi, and specifically the effect of existing Village Savings and Loan Associations (VSLAs). The survey sample comprised of 40 crop insurance adopters, 40 non-adopters and 40 drop-outs in Bukirasazi and Makebuko communes of Gitega province.
The results indicated that saving money (by VSLAs) for upcoming premium payments and regularly VSLA meetings ...
