abstract: For most of human history hunting has been the primary economic activity of men. Hunted animals are valued for their food energy and nutrients, however, hunting is associated with a high risk of failure. Additionally, large animals cannot be consumed entirely by the nuclear family, so much of the harvest may be shared to others. This has led some researchers to ask why men hunt large and difficult game. The “costly signaling” and “show-off” hypotheses propose that large prey are hunted because the difficulty of finding and killing them is a reliable costly signal of the phenotypic quality of the hunter. These hypotheses were tested using original interview data from Aché (hunter gatherer; n=52, age range 50-76, 46% female) and Tsimané (horticulturalist; n=40, age range 15-77, 45% female) informants. Ranking tasks and paired comparison tasks were used to determine the association between the costs of killing an animal and its value as a signal of hunter phenotypic quality for attracting mates and allies. Additional tasks compared individual large animals to groups of smaller animals to determine whether assessments of hunters’ phenotypes and preferred status were more impacted by the signal value of the species or by the weight and number of animals killed. Aché informants perceived hunters who killed larger or harder to kill animals as having greater provisioning ability, strength, fighting ability, and disease susceptibility, and preferred them as mates and allies. Tsimané informants held a similar preference for hunters who killed large game, but not for hunters targeting hard to kill species. When total biomass harvested was controlled, both populations considered harvesting more animals in a given time period to be a better signal of preferred phenotypes than killing a single large and impressive species. Male and female informants both preferred hunters who consistently brought back small game over hunters who sometimes killed large animals and sometimes killed nothing. No evidence was found that hunters should forgo overall food return rates in order to signal phenotypic qualities by specializing on large game. Nutrient provisioning rather than costly phenotypic signaling was the strategy preferred by potential mates and allies. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2019

There have been a number of support initiatives rendered to the small-scale sugarcane farmers in Mpumalanga but the sugarcane production there has remained low. This raised some questions on the efficient use of available resources and the fruitfulness of the Producer Development Initiatives (PDIs). Justification for further assistance to the small-scale farmers requires empirical evidence of efficient resource use. This study employed the stochastic frontier production function to calculate the technical, allocative and cost efficiency. This study provides insight into three issues: the levels of technical, economic and allocative efficiencies of small-scale sugarcane farmers; the relationship between efficiency level and various farm/farmer specific factors; and implications of policy and strategies for improving small-scale sugarcane production. The technical, allocative and economic efficiencies of small-scale sugarcane farming were estimated in order to identify the potential increase in production without incurring additional costs. The study used data obtained from a field survey covering 231 small-scale sugarcane farmers in the Nkomazi region for the 2009/2010. sugarcane production season. According to the stochastic frontier production function using the Cobb-Douglas model, labour, herbicides and fertilizer showed significant positive effects on sugarcane production. The results also indicated that the small-scale sugarcane farmers suffer from considerable lack technical, allocative and cost efficiency. The mean technical, allocative and cost efficiency estimates are 68.5%, 61.5% and 41.8% respectively. A Tobit regression was used to analyse the impact of the farm/farmer characteristics on efficiency. The impact analysis revealed that age, level of education and gender are significant determinants of technical efficiency. On the other hand, level of education, off-farm income, land size and experience are significant determinants of allocative efficiency. In so far as cost efficiency is concerned, the significant determinants are level of education, land size and experience in sugarcane farming. The findings of the study justify the need for improved agricultural partnerships between the sugar mills and the sugarcane farmers. An example of such collaboration would be if millers were to not only give credit to the farmers, but also give technical guidance to small producers in return for the delivery of a specific quantity and quality of cane at a stipulated time. The collective efforts of these farmers and millers, once harmoniously co-ordinated, can enhance production efficiency and economic prosperity. Also, appropriate policy formulation and implementation is an effective instrument to improvement in farm efficiency and productivity which promotes overall growth of the economy. Therefore, there is need for all stakeholders (both private and public sector) to make combined efforts to remove the bottlenecks that have constrained effective policy implementation in, and its accrued benefits to, South African agriculture. / Dissertation MSc (Agric)--University of Pretoria, 2013. / gm2014 / Agricultural Economics, Extension and Rural Development / unrestricted

The aim of this study is twofold; To analyse and understand how well small-scale farmers seed production system from i.e Ladakh, India have been recognised in the 1966 seed policy bill and compare it with the newly released 2019 seed policy draft as well as examining potential effects if the draft is enacted. This has been done by using a post-structural policy analysis developed by Carol Bacchi and Susan Goodwin called “What is the problem represented to be”. The method has enabled for an in-depth and critical examination of the two policies in relation to the posed research questions. To be able to put the result into context and answer the questions, an analytical framework made frompost-structuralism, power relations and literature review is explained. This study concludes the problem representation to be the same for both policies, being disbelief in farmers seed production system, and that it is of disadvantage for the small-scale farmers in relation to seeds in Ladakh. This, due to its definitions and expressions of farmers and the liberal/neoliberal reasoning. Instead, the reasoning gives advantage to seed dealers and companies by favouriting Intellectual Property Rightsand a free market over farmers seed production systems and knowledges. Furthermore, this revelation resulted in a low representation for the small-scale farmers in Ladakh as they are viewed as inept of providing seeds of good quality to the market. It has also been noted that Ladakh as a remote area does not receive any special attention regarding their unique high-mountainous climate. Conclusively, the policies tend to subject all areas and farmers in India in a homogenous manner which is problematic in terms of rationality and perspectives in the policies. The lack of recognition for smallscale farmers in Ladakh and their seed production system increases the risk of further environmentaldegradation, loss heirloom seeds connected to culture and traditions and an increase of dependency onlow-land India. The author concludes that it is of relevant that small-scale farmers knowledges, not only from Ladakh, regarding seed production are incorporated in the policies. This, to eradicate on its homogeneous and inequality traits as well to minimize threatening scenarios that might result from a liberal agenda.

Thesis (M.Sc. Agriculture (Agricultural Economics) -- University of Limpopo, 2019 / Agriculture has long been argued to be the dominant sector of the South African economy. Despite the huge agricultural potential of the country, the agricultural sector is underperforming in Less Developing Countries (LDCs) to some extent because female small-scale farmers, who play a vital role in agriculture, encounter credit constraints because of their gender and this in turn reduce their productivity. Therefore, the gender gap in terms of access to credit indicates that there is a need to reassess the problem of credit access by small-scale farmers on the basis of gender. This study was carried out in the Greater Letaba Municipality (GLM) which is situated in the Mopani District of Limpopo Province, with the aim of analysing factors that influence formal credit access by both female and male small-scale farmers. Structured questionnaires were employed to collect the data for the analyses from 140 sampled small-scale farmers (70 males and 70 females) selected using stratified random sampling technique. The findings of the probit regression model discovered that gender, extension services, land ownership, age, collateral and farm size had a significant positive influence on small-scale farmers` access to formal credit in the GLM. Additionally, the findings further revealed that household size, farming experience, farm-income, marital status had an insignificant negative influence on the small-scale farmers` access to formal credit whereas education level had an insignificant positive influence on the small-scale farmers` access to formal credit. On average, male and female small-scale farmers with access to formal credit were 71 % and 29 %, respectively whereas the male and female small-scale farmers without access to formal credit were 35% and 65%, respectively. The female small-scale farmers` perceptions towards the credit system that were derived from the Principal Component Analysis (PCA) are as follows: (i) male smallscale farmers effortlessly get credit from banks contrasted with their female counterparts, (ii) small-scale farmers with more education and collateral tend to access formal credit than their counterparts and (iii) small-scale farmers who are nearest to iii the banks are more likely to access credit than small-scale farmers who are far away. Based on the study findings, a set of recommendations for achieving equitable formal credit access by male and female small-scale farmers were put forward. / National Research Fund (NRF)

Thesis (M.Sc. Agriculture (Agricultural Economics)) -- University of Limpopo, 2019 / Agriculture plays a significant role also serves as a critical economic sector in Limpopo province in terms of its contribution to the economy, and the number of employment opportunities it produces within local communities. The majority of people involved in agricultural practices are emerging farmers and smallholder/small scale farmers. These farmers try to earn a living from the production of livestock, broilers, fruits & vegetables, and cereals. Cowpea is a drought-tolerant legume that also serves as a staple food for the majority of Africans alongside maize and other typical staple foods consumed by most Africans. The crop is regarded as a key protein source for urban and rural poor, and plays an important role as a cash crop. Despite several nutritional benefits, economic importance and welfare enhancing potential of cowpea, farmers still do not have sufficient information on knowledge about the value that can be added to their cowpea production also the potential and competitiveness of this traditional leafy vegetable. The aim of the study was to map the value chain and determine the marketing efficiency of smallholder cowpea farmers in Capricorn and Waterberg districts of Limpopo province. The specific objectives were to: identify and describe socioeconomic characteristics of smallholder cowpea farmers in Capricorn and Waterberg districts of Limpopo province, identify and define the participants along the cowpea value chain and identify marketing constraints among smallholder cowpea farmers. Structured questionnaire was used to collect data from 80 smallholder cowpea farmers in Ga-Molepo of Capricorn district and Bela-Bela of Waterberg district using purposive sampling technique. Value chain mapping, descriptive statistics and binary logistic regression model were used in addressing the objectives. In identifying and defining the participants along the cowpea value chain, a value chain map was constructed to show the different stages cowpea goes through before reaching the final consumer. Two null hypotheses were formulated. The first hypothesis that stated smallholder cowpea farmers were inefficient in marketing cowpea was rejected. Marketing efficiency measure used to determine each farmer’s marketing efficiency revealed that 66% of smallholder cowpea farmers were efficient. The determinants of marketing efficiency were examined using binary logistic regression model. The second hypothesis stated that socioeconomic characteristics of smallholder cowpea farmers have no effect on the marketing efficiency. The v hypothesis was also rejected based on binary logistic results that revealed that age, household size, years in schooling, years in farming cowpea, income generated from selling cowpea, quantities of cowpea sold and occupation of the farmers were found to be significant in determining marketing efficiency of smallholder cowpea farmers. Pests, lack of access to formal markets and lack of information on how to process cowpea were major constraints farmers were faced with. It was recommended that value chain analysts, policy makers and extension workers together with other stakeholders assist in ensuring that food value chain relationships are established so that market opportunities can be created for smallholder cowpea farmers. In addition, farmer schools need to be introduced in rural areas were agricultural practices are dominant. At these schools, farmers can be taught about basic knowledge relating to agricultural production. Training should also be given to farmers on adopting technology as it can potentially assist in making production more efficient. / Water Research Commission (WRC)

The aim of this thesis is to increase the understanding of small-scale green energy technology development. In the transition towards a fossil free energy system, heat pumps are a low emission heating alternative. Contrary to other types of new small-scale green energy technology such as solar cells and electric vehicles, heat pumps are established on the Swedish market, with more than half the share of single family buildings. This makes it possible to study an example of a mature technology, and that knowledge could be used in the development and deployment of other technologies with similar small-scale green characteristics. The type of heat pump technology studied is ground source heat pumps, and their development is explored from an economic and performance perspective, using the concept of learning. Learning tracks how a product develops for each doubling of units produced. The results show that the efficiency has increased by a learning rate of 2.8 %. When the effects of a low-temperature heating system is included, the learning rate is even higher, 5.8 %. The efficiency improvement is mainly due to new and more expensive components, which has resulted in a price increase. Even if the price slightly decreased until 2008, it has increased with 29 % since. Nevertheless, the ground source heat pump is profitable compared to several other heating technologies. The most important factors underpinning the development are regulations, competition among manufacturers and research.

The North West Province (NWP) identified dairy farming as a priority as it has the potential, not only for job creation, but also as a sustainable source of high quality protein for rural communities. With the correct type of management systems, small-scale dairy farms have the potential to be economically feasible. For the purposes of this study, a small-scale dairy farm was defined as a farm which produced less than 500 litres of milk a day irrespective of the number of cows or size of the farm. The study area was Central North West Province and the study was a longitudinal observational study conducted with 15 small-scale dairy farmers from 2002-2006. Nutrition was found to be a major constraint to the production capacity of dairy cows studied. It was found that farmers were deficient in the knowledge, skills and experience required to develop an affordable and balanced feeding system based on locally available ingredients. Dairy rations were given to prevent malnutrition or starvation, rather than to increase production. It was also shown that feeding of the cattle on the farms investigated, was influenced more by availability and affordability of locally obtained feed ingredients than by planning nutrition to increase milk production. Available statistics show that there are approximately 257 000 dairy cattle in NWP, with the greatest numbers in the Central Region (175 235) and smaller numbers in the Western (59 852) and Eastern (21 873) Regions. These cattle produced approximately 230.4 million litres of milk annually (12.5% of national production) with an estimated value of R304.1 million at R1.32/l, excluding value-added products in the form of cheese, yoghurt, milk powder, and others in 2002. The method used was a longitudinal study conducted from 2002 to 2006 in three phases. In the first phase, situational analysis using participatory rural appraisal (PRA) and observation was used to outline the extent of the constraints and start to design appropriate interventions. Feeds used by the farmers for feeding dairy cows – both supplements and roughage - were tested and evaluated. In the second phase, three different feeding systems were designed from the data obtained from PRA, in consultation with small-scale dairy farmers, established commercial dairy farmers, state veterinary and agriculture staff, feed manufacturers and distributors and the commodity organization (MPO) to optimize the nutrition of the dairy cows. The third phase was field testing of interventions and observations of the implementation by farmers. It was found during the PRA phase that the majority (n=9) of farmers had been in dairy farming for not more than five years, five farmers had six to ten years in dairy farming and only one farmer had 11 to 15 years in dairy farming. Dairy farming is a very highly skilled operation and farmers need to have experience and knowledge to succeed. Five years is insufficient. Therefore capacity building and training were instituted over the period 2002 to 2005. Also, 60% (n=9) of the farmers were not affiliated to any agricultural organisation, so membership of the Milk Producers Organisation was facilitated for all farmers in the study. It was also found that the cattle were not identified and neither production nor financial records were kept. Testing and evaluation of feed used showed that it was of poor quality, deficient in protein, energy and minerals and no effort was made to balance the ration. In the second phase, three feeding systems were developed form data obtained and observations during phase one. These were A: a semi-intensive farm based ration using available crops, pastures and crop residues with minimal rations purchased; B: an intensive, zero-grazing dairy system using a total mixed ration (TMR) for farmers with smallholdings of less than 5 hectares per cow and C: Traditional, extensive or dual purpose system where the calf drank from the cow until weaning and milking was done only once a day, for farmers with more than 5 ha grazing available per cow. The last was a low-input/low output system and was implemented by a majority (n=8) of the farmers. System B was chosen by two farmers and not adopted by any of the two farmers in the long run. System A was adopted by three farmers. Four farmers left dairy farming for various reasons during the study. By July 2006, the farmers had changed to commercially formulated rations or licks and the body condition score of the cows had improved. Milk production per cow did not increase, but this may have been due to the increased price of meat and the fact that a majority of the farmers were using a dual purpose system and selling calves at weaning for a very good price. It was concluded that extension officers should get extra training in dairy if there are dairy farmers in their areas as this is a very specialist type of extension. They should also work closely with veterinary services including veterinarians, animal health technicians and the health inspectors. Further research should be done to optimise the traditional model as this is relatively profitable, has a lower risk and is less labour intensive. It is probably a good way to increase food security, particularly in families when only one or two members have an income from a pension or part-time employment. The prices realised from informal sales of milk and calves can give a stable income. The “community farms” should be economically evaluated in terms of each beneficiary being able to get a “living wage” out of the projected profits of the farm. The MPO and other stakeholders should give very specific training to new dairy farmers, based on the models that were used in this study. It is essential that framers be taught to “look forward” and get a pro-active attitude. They must also understand that quality, balanced rations are the key to success – poor rations are expensive rations, because they result in unhealthy cows and poor production. Finally, ongoing and effective monitoring and evaluation of extension is an effective instrument for project sustainability – farmers must be involved and participate in their own evaluation - extension is not all about paper work it is about measuring performance and good service delivery. / Dissertation (MSc (Veterinary Science))--University of Pretoria, 2007. / Paraclinical Sciences / unrestricted

The total energy demand in the world is expected to increase in the future years due to thehigh development rate of developing countries. Access to energy enables development, butthe current global energy mix has to be modified if a sustainable growth is desired. Renewableenergy sources (RES) benefit from both a political and economic support from manygovernments and international entities. The growing installation of RES takes place both inlarge scale, as wind farms with sizes 10 – 1000 MW, and in small scale in homes or smallenterprises with sizes 100 W – 100 kW. Small scale wind power connected to the grid is rarenowadays except in the case of remote mini-grids. By contrast, small scale solar photovoltaic(PV) power is being more and more commonly installed, especially in the form of investorownedroof-installed units. Taking increasing small scale solar and wind power into accountin network planning is a challenge faced by the distribution system operator (DSO).The aim of this thesis is to present a guideline that assists DSOs when planning lowvoltage (LV) distribution networks (DN) with a large amount of small scale distributedgeneration (DG) on a short-term perspective. A review on integration issues of DG isperformed and over-voltage constraints are identified as the most relevant issue. Simple ruleshave already been designed for individual DG units, as the one presented in the AMKhandbookpublished by Svensk Energi; but these are not valid any more when consideringmore than one DG unit. The new proposed guideline employs the AMK-handbook as astarting point and develops it further by including the interaction between DG units. Theguideline is then applicable to scenarios with more than one DG unit. The maximum capacityof a new DG unit applying for a connection to a grid is calculated based on the location andcapacity of the already installed DG units, and without any reinforcement. The proposedguideline can be applied under no load and minimum load condition.Since this thesis is a collaboration project between KTH-Royal Institute of Technologyand Vattenfall R&D, two specific Swedish LV distribution networks owned by VattenfallEldistribution AB are studied. Scenarios with different penetration levels of DG, with valuesbetween 12% and 71%, and capacity of individual DG units below 43.5 kW are analyzed.Evaluation of the results shows that the proposed guideline leads to acceptable results. Thedevelopment of future simple guidelines is suggested to be based on the following twoaspects: absolute and relative location of the DG units; and a correct identification of the weakbus. Relative location reveals the interaction with other DG units within the DN. Moreover, itis stated that the use of the penetration level as a planning measure, based on the total DGcapacity, has a limited application.
