Local dynamics and external drivers of agro-ecological change in Southwestern Ethiopia

Hedtjärn Swaling, Julia January 2012 (has links)
While previous research on African smallholder agriculture has been criticized of focusing on the sole factor of population pressure as driver of agricultural degradation or intensification, the present study tries to nuance this debate by providing empirically grounded research, exploring the dynamics behind local agro-ecological change. The thesis specifically studies the dynamics behind small-scale farmers’ crop choices in relation to their management of trees in cropland in Gera District, Ethiopia. Drawing on situated landscape interviews and focus group discussions with farmers combined with observations and interviews with agriculture officials, a contextual understanding of local agro-ecological processes emerged. While political ecology was used as an overarching framework, the concept of landesque capital served as an analytical tool to explore how external and local forces interact at the point of the land management decision. It was found that external factors sometimes have a reinforcing effect at the local scale, but when top-down interventions are incoherent with bottom-up priorities, a conflict occurs. In this way, local dynamics and external drivers constitute an interacting dialectic, with a set of unintentional synergies and trade-offs eventually forming agro-ecological landscape change. / Examining mismatches between management and the supply of ecosystem services in Ethiopian agroecosystems across scales in space and time

East African Hydropatriarchies : An analysis of changing waterscapes in smallholder irrigation farming

Caretta, Martina Angela January 2015 (has links)
This thesis examines the local waterscapes of two smallholder irrigation farming systems in the dry lands of East African in a context of socio-ecological changes. It focuses on three aspects: institutional arrangements, gender relations and landscape investments.  This thesis is based on a reflexive analysis of cross-cultural, cross-language research, particularly focusing on the role of field assistants and interpreters, and on member checking as a method to ensure validity. Flexible irrigation infrastructure in Sibou, Kenya, and Engaruka, Tanzania, allow farmers to shift the course of water and to extend or reduce the area cultivated depending on seasonal rainfall patterns. Water conflicts are avoided through a decentralized common property management system. Water rights are continuously renegotiated depending on water supply. Water is seen as a common good the management of which is guided by mutual understanding to prevent conflicts through participation and shared information about water rights. However, participation in water management is a privilege that is endowed mostly to men. Strict patriarchal norms regulate control over water and practically exclude women from irrigation management. The control over water usage for productive means is a manifestation of masculinity. The same gender bias has emerged in recent decades as men have increased their engagement in agriculture by cultivating crops for sale. Women, because of their subordinated position, cannot take advantage of the recent livelihood diversification. Rather, the cultivation of horticultural products for sale has increased the workload for women who already farm most food crops for family consumption. In addition, they now have to weed and harvest the commercial crops that their husbands sell for profit. This agricultural gender divide is mirrored in men´s and women´s response to increased climate variability. Women intercrop as a risk adverting strategy, while men sow more rounds of crops for sale when the rain allows for it. Additionally, while discursively underestimated by men, women´s assistance is materially fundamental to maintaining of the irrigation infrastructure and to ensuring the soil fertility that makes the cultivation of crops for sale possible. In sum, this thesis highlights the adaptation potentials of contemporary smallholder irrigation systems through local common property regimes that, while not inclusive towards women, avoid conflicts generated by shifting water supply and increased climate variability. To be able to assess the success and viability of irrigation systems, research must be carried out at a local level. By studying how local water management works, how conflicts are adverted through common property regimes and how these systems adapt to socio-ecological changes, this thesis provides insights that are important both for the planning of current irrigation schemes and the rehabilitation or the extension of older systems. By investigating the factors behind the consistent marginalization of women from water management and their subordinated role in agricultural production, this study also cautions against the reproduction of these discriminatory norms in the planning of irrigation projects. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 4: Manuscript.</p><p> </p>

Small-Scale Farmers Land Use and Socioeconomic Situation in the Mount Elgon District in Northwestern Kenya : A Minor Field Study - Combined Field Mapping and Interview

Kaati, Patrik January 2011 (has links)
This Minor Field Study was carried out during November and December in 2011 in the Mount Elgon District in Western Kenya. The objective was to examine nine small-scale farming household´s land use and socioeconomic situation when they have joined a non-governmental organization (NGO) project, which specifically targets small-scale farming households to improve land use system and socioeconomic situation by the extension of soil and water conservation measures. The survey has worked along three integral examinations methods which are mapping and processing data using GIS, semi structured interviews and literature studies.   This study has adopted a theoretical approach referred to as political ecology, in which landesque capital is a central concept. The result shows that all farmers, except one, have issues with land degradation. However, the extent of the problem and also implemented sustainable soil and water conservation measures were diverse among the farmers. The main causes of this can both be linked to how the farmers themselves utilized their farmland and how impacts from the climate change have modified the terms of the farmers working conditions. These factors have consequently resulted in impacts on the informants’ socioeconomic conditions. Furthermore it was also registered that social and economic elements, in some cases, were the causes of how the farmers manage their farmland. The farmer who had no significant problem with soil erosion had invested in trees and opportunities to irrigate the farmland. In addition, it was also recorded that certain farmers had invested in particular soil and water conservation measures without any significant result. This was probably due to the time span these land measures cover before they start to generate revenue.  The outcome of this study has traced how global, national and local elements exist in a context when it comes to the conditions of the farmers´ land use and their socioeconomic situation. The farmers atMt.Elgon are thereby a component of a wider context when they are both contributory to their socioeconomic situation, mainly due to their land management, and also exposed to core-periphery relationships on which the farmers themselves have no influence.

A History under Siege : Intensive Agriculture in the Mbulu Highlands, Tanzania, 19th Century to the Present

Börjeson, Lowe January 2004 (has links)
This doctoral thesis examines the history of the Iraqw’ar Da/aw area in the Mbulu Highlands of northern Tanzania. Since the late nineteenth century this area has been known for its intensive cultivation, and referred to as an “island” within a matrix of less intensive land use. The conventional explanation for its characteristics has been high population densities resulting from the prevention of expansion by hostility from surrounding pastoral groups, leading to a siegelike situation. Drawing on an intensive programme of interviews, detailed field mapping and studies of aerial photographs, early travellers’ accounts and landscape photographs, this study challenges that explanation. The study concludes that the process of agricultural intensification has largely been its own driving force, based on self-reinforcing processes of change, and not a consequence of land scarcity.
