From dependency to Interdependencies: The emergence of a socially rooted but commercial waste sector in Kampala City, Uganda

Urban waste has traditionally remained for municipal councils to manage in several sub-Saharan cities such as Kampala. However, due to noticeable inefficiencies at municipal level, there is a manifest of low-income groups that take the initiative to extract and add value to materials from the waste stream, although higher-income groups are engaged in similar activities. This signifies the gradual shift from dependency on municipal councils to neighborhood interdependencies in the management of urban waste. To gain an in-depth understanding of this shift, we conducted purposive observations and twelve (12) focused-group interviews amongst selected respondents, in the neighborhood of Kasubi-Kawaala, Makerere II and Bwaise III parishes, located in the north western part of Kampala. The key finding was that waste-user roles, preferences, and the preceding generation and extraction processes are socially rooted in neighborhood cultural-orientations, and the underlying social mobility and commercial drivers. From the study, three (3) types of low-income commercial waste vendors were identified including, regular waste vendors, wholesale waste dealers, and home to home waste dealers. Unfortunately, these low-income waste vendors still have the least opportunity to negotiate with municipal authorities on scaling-up their commercial activities for a greater social impact.Key words: Wastes, social rootedness, neighborhoods, commercial waste, Kampala City

Multiple interests in urban land: disaster-induced land resettlement politics in Kampala

One of the actions that many local authorities take in to reduce exposure of informal settlements to disaster risks and the impacts of climate change is to move people out of high-risk areas. This is usually enacted through resettlement, relocation or evictions. This article argues that local authorities recognizing and validating multiple interests in land offers an innovative advantage to cities in equitably responding to risks, and adapting to climate change. More specifically, we focus on how multiple interests in land in Kampala influenced processes associated with the resettlement of people within the context of trying to reduce exposure to disaster risks. In this instance, authorities seeking to resettle people were more inclined to negotiate than impose resettlement and these negotiations opened up the possibilities for more equitable outcomes to emerge, such as staying in their existing communities. The experience of Kampala’s authorities offers lessons for other cities confronting resettlement challenges

Value chain analysis and mapping for groundnuts in Uganda, Socioeconomics Discussion Paper Series Number 14

Groundnut is grown on about 23.95 million ha worldwide with the total production of 36.45 million tons and an average yield of 1520 kg/ha in 2009 Developing countries in Asia, Africa and South America account for about 97% of world groundnut area and 95% of total production. It is one of the important legumes grown in Uganda, ranking second after beans. Its production is most common in Northern, Eastern and Southern parts of the country with higher volumes being produced in the Eastern part compared to the other two. The value chain for groundnuts in Uganda consist of many actors (individuals and institutions) including input suppliers and seed dealers, producers, market sellers, rural traders, urban traders, processors, exporters and consumers. The general objective of this study was to map the value chain for groundnuts, indicating the opportunities that value chain actors can benefit from and strategies that can be used to upgrade the chain. The specific objectives were to characterize the key actors along the groundnut value chain; determine the costs and value added along the groundnut value chain; determine the level of awareness of health problems associated with groundnuts; and determine the constraints and opportunities in the value chain and suggest ways to upgrade the chain. A cross sectional survey was conducted among the key actors in the value chain in 16 purposively selected districts in Uganda where groundnuts are predominantly produced marketed and/or consumed. The districts are Arua in North western Uganda, Lira in the North, Bugiri, Bukedea, Busia, Iganga, Jinja Kaberamaido, Mbale, Pallisa, Kumi and Tororo in Eastern Uganda; Soroti and Katakwi in the North east, Kampala and Wakiso in Central where a total of 145 wholesale traders, 209 retail traders wand 51 processors were randomly selected and interviewed. In addition, data collected by NARO from a total of 314 randomly selected groundnut farmers were used in this study.The data collected included socio-economic characteristics of the value chain actors, type and varieties of groundnuts handled, sales volumes and prices, trends in demand and supply, aflatoxins awareness and control, challenges, constraints and opportunities in groundnuts and trade policy related issues

Estimation of the aboveground biomass in the trans-boundary River Sio Sub-catchment in Uganda

The enormous land cover in Uganda is rapidly being depleted or encroached. To examine this, the study aimed at estimating the above-ground biomass in River Sio sub-catchment in Uganda. The study utilized an ortho-rectified Landsat TM/ETM image of 2004 which was classified using NDVI classification system for the aboveground biomass assessment in ILWIS 3.3 software. A total of 42 homogenous sampling sites were identified for biomass estimation along six laid transects measuring 500m long. The seven randomly selected sampling plots measured 50m X 50 m. The classification showed that Bushlands (0.17), wetlands (0.03) and small scale farming (- 0.29-0.03) had relatively more medium and low biomass ranges compared to grasslands (-0.41/-0.29) which mainly comprised of bare land. The above ground biomass was relatively higher in bushlands (4.9 tons) and wetlands (4.7 tons) compared to non-uniform small scale farming (farmlands) with 3.9 tons and grasslands with 1.6 tons. The variation in biomass shows that the sub-catchment requires an urgent need for land use/cover planning and management to prevent further degradation of land cover

Seasonal variation of food security among the Batwa of Kanungu, Uganda

Climate change is projected to increase the burden of food insecurity (FI) globally, particularly among populations that depend on subsistence agriculture. The impacts of climate change will have disproportionate effects on populations with higher existing vulnerability. Indigenous people consistently experience higher levels of FI than their non-Indigenous counterparts and are more likely to be dependent upon land-based resources. The present study aimed to understand the sensitivity of the food system of an Indigenous African population, the Batwa of Kanungu District, Uganda, to seasonal variation. A concurrent, mixed methods (quantitative and qualitative) design was used. Six cross-sectional retrospective surveys, conducted between January 2013 and April 2014, provided quantitative data to examine the seasonal variation of self-reported household FI. This was complemented by qualitative data from focus group discussions and semi-structured interviews collected between June and August 2014. Ten rural Indigenous communities in Kanungu District, Uganda. FI data were collected from 130 Indigenous Batwa Pygmy households. Qualitative methods involved Batwa community members, local key informants, health workers and governmental representatives. The dry season was associated with increased FI among the Batwa in the quantitative surveys and in the qualitative interviews. During the dry season, the majority of Batwa households reported greater difficulty in acquiring sufficient quantities and quality of food. However, the qualitative data indicated that the effect of seasonal variation on FI was modified by employment, wealth and community location. These findings highlight the role social factors play in mediating seasonal impacts on FI and support calls to treat climate associations with health outcomes as non-stationary and mediated by social sensitivity

Conservation Farming and Changing Climate: More Beneficial Than Conventional Methods for Degraded Ugandan Soils

The extent of land affected by degradation in Uganda ranges from 20% in relatively flat and vegetation-covered areas to 90% in the eastern and southwestern highlands. Land degradation has adversely affected smallholder agro-ecosystems including direct damage and loss of critical ecosystem services such as agricultural land/soil and biodiversity. This study evaluated the extent of bare grounds in Nakasongola, one of the districts in the Cattle Corridor of Uganda and the yield responses of maize (Zea mays) and common bean (Phaseolus vulgaris L.) to different tillage methods in the district. Bare ground was determined by a supervised multi-band satellite image classification using the Maximum Likelihood Classifier (MLC). Field trials on maize and bean grain yield responses to tillage practices used a randomized complete block design with three replications, evaluating conventional farmer practice (CFP); permanent planting basins (PPB); and rip lines, with or without fertilizer in maize and bean rotations. Bare ground coverage in the Nakasongola District was 187 km2 (11%) of the 1741 km2 of arable land due to extreme cases of soil compaction. All practices, whether conventional or the newly introduced conservation farming practices in combination with fertilizer increased bean and maize grain yields, albeit with minimal statistical significance in some cases. The newly introduced conservation farming tillage practices increased the bean grain yield relative to conventional practices by 41% in PPBs and 43% in rip lines. In maize, the newly introduced conservation farming tillage practices increased the grain yield by 78% on average, relative to conventional practices. Apparently, conservation farming tillage methods proved beneficial relative to conventional methods on degraded soils, with the short-term benefit of increasing land productivity leading to better harvests and food security

Estimation of the aboveground biomass in the trans-boundary River Sio Sub-catchment in Uganda

The enormous land cover in Uganda is rapidly being depleted or encroached. To examine this, the study aimed at estimating the above-ground biomass in River Sio sub-catchment in Uganda.

A total of 42 homogenous sampling sites were identified for biomass estimation along six laid transects measuring 500m long. The seven randomly selected sampling plots measured 50m X 50 m. The classification showed that Bushlands (0.17), wetlands (0.03) and small scale farming (0.29-0.03) had relatively more medium and low biomass ranges compared to grasslands (-0.41/-0.29) which mainly comprised of bare land. The above ground biomass was relatively higher in bushlands (4.9 tons) and wetlands (4.7 tons) compared to non-uniform small scale farming (farmlands) with 3.9 tons and grasslands with 1.6 tons. The variation in biomass shows that the sub-catchment requires an urgent need for land use/cover planning and management to prevent further degradation of land cover. @JASE

Thinking through heterogeneous infrastructure configurations

Studies of infrastructure have demonstrated broad differences between Northern and Southern cities, and deconstructed urban theory derived from experiences of the networked urban regions of the Global North. This includes critiques of the universalisation of the historically–culturally produced normative ideal of universal, uniform infrastructure. In this commentary, we first introduce the notion of ‘heterogeneous infrastructure configurations’ (HICs) which resonates with existing scholarship on Southern urbanism. Second, we argue that thinking through HICs helps us to move beyond technological and performative accounts of actually existing infrastructures to provide an analytical lens through which to compare different configurations. Our approach enables a clearer analysis of infrastructural artefacts not as individual objects but as parts of geographically spread socio-technological configurations: configurations which might involve many different kinds of technologies, relations, capacities and operations, entailing different risks and power relationships. We use examples from ongoing research on sanitation and waste in Kampala, Uganda – a city in which service delivery is characterised by multiplicity, overlap, disruption and inequality – to demonstrate the kinds of research questions that emerge when thinking through the notion of HICs

Examination of Antibody Responses as a Measure of Exposure to Malaria in the Indigenous Batwa and Their Non-Indigenous Neighbors in Southwestern Uganda

Understanding variations in malaria transmission and exposure is critical to identify populations at risk and enable better targeting of interventions. The indigenous Batwa of southwestern Uganda have a disproportionate burden of malaria infection compared with their non-indigenous neighbors. To better understand the individual- and community-level determinants of malaria exposure, a seroepidemiological study was conducted in 10 local council cells in Kanungu District, Uganda, in April 2014. The Batwa had twice the odds of being seropositive to two Plasmodium falciparum–specific antigens, apical membrane antigen-1 and merozoite surface protein-119, compared with the non-indigenous Bakiga (odds ratio = 2.08, 95% confidence interval = 1.51–2.88). This trend was found irrespective of altitude level and after controlling for cell location. Seroconversion rates in the Batwa were more than twice those observed in the Bakiga. For the Batwa, multiple factors may be associated with higher exposure to malaria and antibody levels relative to their non-indigenous neighbors
