The broiler meat system in Nairobi, Kenya: using a value chain framework to understand animal and product flows, governance and sanitary risks
Livestock food systems play key subsistence and income generation roles in low to middle income countries and are important networks for zoonotic disease transmission. The aim of this study was to use a value chain framework to characterize the broiler chicken meat system of Nairobi, its governance and sanitary risks.
A total of 4 focus groups and 8 key informant interviews were used to collect cross-sectional data from: small-scale broiler farmers in selected Nairobi peri-urban and informal settlement areas; medium to large integrated broiler production companies; traders and meat inspectors in live chicken and chicken meat markets in Nairobi. Qualitative data were collected on types of people operating in the system, their interactions, sanitary measures in place, sourcing and selling of broiler chickens and products. Framework analysis was used to identify governance themes and risky sanitary practices present in the system.
One large company was identified to supply 60% of Nairobiâs day-old chicks to farmers, mainly through agrovet shops. Broiler meat products from integrated companies were sold in high-end retailers whereas their low value products were channelled through independent traders to consumers in informal settlements. Peri-urban small-scale farmers reported to slaughter the broilers on the farm and to sell carcasses to retailers (hotels and butcheries mainly) through brokers (80%), while farmers in the informal settlement reported to sell their broilers live to retailers (butcheries, hotels and hawkers mainly) directly. Broiler heads and legs were sold in informal settlements via roadside vendors.
Sanitary risks identified were related to lack of biosecurity, cold chain and access to water, poor hygiene practices, lack of inspection at farm slaughter and limited health inspection in markets.
Large companies dominated the governance of the broiler system through the control of day-old chick production. Overall government control was described as relatively weak leading to minimal official regulatory enforcement. Large companies and brokers were identified as dominant groups in market information dissemination and price setting. Lack of farmer association was found to be system-wide and to limit market access. Other system barriers included lack of space and expertise, leading to poor infrastructure and limited ability to implement effective hygienic measures.
This study highlights significant structural differences between different broiler chains and inequalities in product quality and market access across the system. It provides a foundation for food safety assessments, disease control programmes and informs policy-making for the inclusive growth of this fast-evolving sector
Where are mines located in subâSaharan Africa and how have they expanded overtime?
Mining is a multiâbillionâdollar industry spanning major to artisanal and smallâscale mines, with diverse local to regional socioâeconomic and environmental impacts. SubâSaharan Africa (SSA) has large deposits of minerals, which has made it a global epicentre for investors in the extractive industries. Here, we identified and mapped 469 companyâowned and communityâmanaged mines across SSA, most of which are formal, to explore their distribution and areal extents and understand the potential threats they pose to conservation. The dominant eight commodities in SSA are gold, copper, iron, limestone, uranium, diamond, bauxite and petroleum, making up 405 mines and occupying 85% of the 3,055 km2 total areal extent. Mining significantly expanded between 2000 and 2018, with 260 (58%) new mines created and major expansion of many older mines. Hotspots of mining activity are apparent in the copperâbelt of the Democratic Republic of Congo and Zambia, Ghana, and the Nigerâdelta region of Nigeria. These mining âhotspotsâ are distributed in close proximity to regions of high carbon stocks and value to biodiversity conservation, with the areal extent of mines more than doubling between 2000 and 2018 to 1192 km2 within 10 km of a protected area, suggesting susceptibility to deforestation and other environmental consequences. The identification of mines and their changing spatial extent is imperative for monitoring future encroachments in SSA and to conservation and habitat recovery. Furthermore, Africa needs to introduce sustainable mineral development policies to safeguard and protect its forests, especially reducing the frequency of protected area downgrading, downsizing and degazettement (PADDD) events

The roles and values of wild foods in agricultural systems
Almost every ecosystem has been amended so that plants and animals can be used as food, fibre, fodder, medicines, traps and weapons. Historically, wild plants and animals were sole dietary components for hunterâgatherer and forager cultures. Today, they remain key to many agricultural communities. The mean use of wild foods by agricultural and forager communities in 22 countries of Asia and Africa (36 studies) is 90â100 species per location. Aggregate country estimates can reach 300â800 species (e.g. India, Ethiopia, Kenya). The mean use of wild species is 120 per community for indigenous communities in both industrialized and developing countries. Many of these wild foods are actively managed, suggesting there is a false dichotomy around ideas of the agricultural and the wild: hunterâgatherers and foragers farm and manage their environments, and cultivators use many wild plants and animals. Yet, provision of and access to these sources of food may be declining as natural habitats come under increasing pressure from development, conservation-exclusions and agricultural expansion. Despite their value, wild foods are excluded from official statistics on economic values of natural resources. It is clear that wild plants and animals continue to form a significant proportion of the global food basket, and while a variety of social and ecological drivers are acting to reduce wild food use, their importance may be set to grow as pressures on agricultural productivity increase.</jats:p
Transport infrastructure: making more sustainable decisions for noise reduction
There is a global and growing sustainability agenda for surface transport yet there are no specific means of assessing the relative sustainability of infrastructure equipment. Transport noise reduction devices are a significant part of the surface transport infrastructure: they specifically address environmental and social needs, have a high economic impact, and involve a wide range of raw materials raising multiple technical issues. The paper presents an account of the bespoke tool developed for assessing the sustainability of transport noise reduction devices. Regulatory standards for noise reduction devices and the relevant sustainability assessment tools and procedures adopted worldwide were reviewed in order to produce a set of pertinent sustainability criteria and indicators for NRDs projects, which were reviewed and edited during a stakeholder engagement process. A decision making process for assessing the relative sustainability of noise reduction devices was formulated following the review of the literature. Two key stages were identified: (1) collection of data for criteria fulfillment evaluation and (2) multi-criteria analysis for assessing the sustainability of noise reduction devices. Appropriate tools and methods for achieving both objectives are recommended
Integrating livelihoods and conservation in protected areas: Understanding the role and stakeholder views on prospects for non-timber forest products, a Bangladesh case study
Protected areas (PAs) represent a key global strategy in biodiversity conservation. In tropical developing countries, the management of PAs is a great challenge as many contain resources on which local communities rely. Collection and trading of non-timber forest products (NTFPs) is a well-established forest-based livelihood strategy, which has been promoted as a potential means for enhanced conservation and improved rural livelihoods in recent years, even though the sustainability or ecological implications have rarely been tested. We conducted an exploratory survey to understand the role and stakeholder views on conservation prospects and perceived ecological feasibility of NTFPs and harvesting schemes in a northeastern PA of Bangladesh, namely the Satchari National Park. Households (n = 101) were interviewed from three different forest dependency categories, adopting a stratified random sampling approach and using a semi-structured questionnaire. The study identified 13 locally important NTFPs, with five being critically important to supporting local livelihoods. Our study suggests that collection, processing and trading in NTFPs constitutes the primary occupation for about 18% of local inhabitants and account for an estimated 19% of their cash annual income. The household consensus on issues relating to NTFPs and their prospective role in conservation was surprisingly high, with 48% of respondents believing that promotion of NTFPs in the PA could have positive conservation value. The majority (71%) of households also had some understanding of the ecological implications of NTFP harvesting, sustainability (53%) and possible management and monitoring regimes (100%). With little known about their real application in the field, our study suggests further investigations are required to understand the ecological compatibility of traditional NTFP harvesting patterns and management. © 2010 Taylor & Francis
Broadening out and opening up technology assessment: Approaches to enhance international development, co-ordination and democratisation
Technology assessment (TA) has a strong history of helping to identify priorities and improve environmental sustainability, cost-effectiveness and wider benefits in the technology policies and innovation strategies of nation-states. At international levels, TA has the potential to enhance the roles of science, technology and innovation towards achieving the Millennium Development Goals, effectively implementing the UN Framework on Climate Change and fostering general global transitions to âgreen economiesâ. However, when effectively recommending single ostensibly âbestâ technologies or strategies, TA practices can serve unjustifiably to âclose downâ debate, failing adequately to address technical uncertainties and social ambiguities, reducing scope for democratic accountability and co-ordination across scales and contexts. This paper investigates ways in which contrasting processes âbroadening outâ and âopening upâ TA can enhance both rigour and democratic accountability in technology policy, as well as facilitating social relevance and international cooperation. These methods allow TA to illuminate options, uncertainties and ambiguities and so inform wider political debates about how the contending questions, values and knowledges of different social interests often favour contrasting innovation pathways. In this way TA can foster both technical robustness and social legitimacy in subsequent policy-making. Drawing on three empirical case studies (at local, national and international levels), the paper discusses detailed cases and methods, where recent TA exercises have contributed to this âbroadening outâ and âopening upâ. It ends by exploring wider implications and challenges for national and international technology assessment processes that focus on global sustainable development challenges.ESR
Openness in participation, assessment, and policy making upon issues of environment and environmental health: a review of literature and recent project results
Issues of environment and environmental health involve multiple interests regarding e.g. political, societal, economical, and public concerns represented by different kinds of organizations and individuals. Not surprisingly, stakeholder and public participation has become a major issue in environmental and environmental health policy and assessment. The need for participation has been discussed and reasoned by many, including environmental legislators around the world. In principle, participation is generally considered as desirable and the focus of most scholars and practitioners is on carrying out participation, and making participation more effective. In practice also doubts regarding the effectiveness and importance of participation exist among policy makers, assessors, and public, leading even to undermining participatory practices in policy making and assessment
