About 3000 elephants live in the Laikipia/Sambnru region of northern Kenya – the largest remaining population outside the country's formal protected areas. The elephants occasionally kill or injure people, damage the crops of small-scale farmers, drive cattle away from water sources and cause a range of other problems for the human population. As a result, a number of elephants have been shot for control purposes in recent years and others have died as a result of poisoning, snares or spearing. The author examines the conflict between elephants and humans in areas of differing land use and makes suggestions for resolving at least some of the problems.

Tension and conflict are endemic to any upgrading initiative (including basic infrastructure provision) requiring private land contributions, whether in the form of voluntary donations or compensated land acquisitions. In informal urban contexts, practitioners must first identify well-suited land for public infrastructure, both spatially and with careful consideration for safeguarding claimed rights and preventing conflicts. At the same time, they need to defuse existing tensions over land ownership and land use rights while negotiating for the potential use of a unit of land for infrastructure. Even in the case of employing participatory methods, land negotiations are never tension-free. Despite the extensive literature on linkages between urban poverty, inefficient land management systems, and land disputes, in both rural and urban settings, land negotiations for community-scale infrastructure retrofit projects (e.g., neighbourhood roads, water and sanitation infrastructure) are yet to be fully explored. Drawing on a case study of a live green infrastructure retrofit project in six informal settlements in Makassar, Indonesia, we establish links to exchange theory, collective action, and negotiation theory to build a reliable analytical framework for understanding and explaining the land negotiations in small-scale infrastructure retrofit practices. We aim to describe and assess the fundamental conditions for land negotiations in an informal urban context and conclude the paper by summarising several key strategies developed and used in the case study area to forge land agreements.

AbstractDowny brome (Bromus tectorum L.) is a common impediment to ecological restoration, because its seedbank remains viable after repeated treatment with herbicides. Soil solarization has been used in ecological restoration to control seedbanks of invasive plants. Here we test the efficacy of soil solarization to reduce B. tectorum cover and establish native plants at a site in B. tectorum’s core invasive range with a long history of disturbance and infestation. Solarization raised soil temperatures by as much as 13 C and reduced B. tectorum densities by approximately 20-fold. In 30 plots solarized for 0 to 101 d, B. tectorum emerged in inverse abundance to treatment duration. Broadleaf weeds were less abundant than B. tectorum before treatment, and diminished under solarization, but their response to solarization was weaker than B. tectorum’s, and they emerged in greater numbers than B. tectorum 2 to 3 yr after treatment. When seeded after solarization, a native perennial bunchgrass, squirreltail [Elymus elymoides (Raf.) Swezey], did not differ in abundance between solarized and control plots. Solarization may facilitate B. tectorum control on a small scale without jeopardizing the establishment of native plants, but only if treatment durations are long and subsequent management of broadleaf weeds and remnant B. tectorum is planned.

Squatter settlements, widespread in urban Africa, Latin America, and South and Southeast Asia, are a characteristic feature of contemporary urbanization. Also known as shantytowns, slums, favelas in Brazil, and bustees in South Asia, they involve the extralegal occupation and settlement of public or private land, often by migrants from rural areas. Unplanned and typically located on peripheral or marginal land, squatter settlements have poor infrastructure and inadequate public services, including water, health, and sanitation. Houses tend to be auto-constructed and built incrementally. Residents of squatter settlements generally lack legally recognized rights to the land they occupy, and may lead precarious lives. The majority work in the informal economy, in insecure, low-wage jobs or are self-employed. State policies in many countries, seeking to curb a migrant influx to big cities, criminalize land encroachment but fail to address the housing needs of the urban poor. Squatter settlements may be demolished in slum clearance programs. Nonetheless, many such settlements endure and grow, over time acquiring public services and rights. Well-known slums like Mumbai’s Dharavi, Rocinha in Rio de Janeiro, and Nairobi’s Kibera are populous, established, and diverse cities within cities. They are both celebrated and deplored in popular and academic accounts, as symbols of human resilience and entrepreneurship, or products of uneven development and global and national inequities. Early literature on squatter settlements located their growth in the distorted urbanization of what was known as the Third World, divorced from industrial modernization. Squatters were considered economically marginal, akin to peasants rather than “modern” urban citizens. Ethnographic and empirical research complicated these perspectives, providing insight into the lived experience and social, economic, and political organization of squatter settlements. Slums began to be viewed as solutions to challenges of housing, livelihoods, and economic growth. “Self-build” housing was celebrated, as was small-scale entrepreneurship. In-situ improvement and tenure legalization became preferred policy approaches. Later, critical urban theorists rejected notions of “underdevelopment” and development and argued that informal processes such as squatting were integral to urbanization in the Global South. As the world urbanizes, with population growth concentrated in developing world cities, slums have reemerged as sites for social-scientific inquiry. Debates about their relationship to growth and development, their viability as communities and living environments, and about policy approaches and outcomes continue to animate the literature. These debates reflect the fact that squatter settlements across the world, and even within cities, are heterogeneous and dynamic, within varied histories and trajectories.

Once dominant across the United States (US) Southeastern Coastal Plain, the longleaf pine (Pinus palustris Mill.) ecosystem covers a fraction of its historic geographic range. Restoration efforts have largely occurred on public lands, while most private forests feature alternative pine species. A better understanding of public interest in ecological restoration is critical to sustained efforts and successes. This research examines both forest landowner and general public interest in longleaf pine restoration. Results contribute to research on the social dimensions of ecological restoration, much of which has focused on small-scale projects rather than landscape-scale initiatives. In addition, this study addresses the lack of knowledge regarding factors driving attitudes towards ecological restoration other than demographic and psychometric variables. We employed a telephone survey of 2700 participants across eight states in the southeastern US in the historical range of longleaf pine. A majority of respondents supported restoration as a general goal and were supportive of the use of prescribed fire as a restoration practice. Place attachment, knowledge about longleaf pine, and age were among the significant predictors of restoration support. Findings have implications for future research focusing on sociocultural influences of restoration projects, as well as expanded public support for restoration of fire-maintained ecosystems.

AbstractAgricultural programme planners have commonly assumed that, to adopt new crops and inputs, small-scale farmers need financial loans, and that private land titles help them to borrow by providing a form of collateral for mortgages. The experience of the over 2 million Luo people and others in Kenya shows how inappropriate this theory can be in a tropical African context.With a land-holding system based on patriliny, the hosting of in-laws, and other principles, Luo tend to live among kin. They continue to justify land claims largely by labour, by the presence of ancestral graves, and by the group membership these represent. These patterns persist despite individual titling by the government since the 1950s. Financial institutions trying to foreclose on defaulters, and buyers trying then to move on to those lands, face stiff social a~hd political resistance, sometimes violent. The government land register obsolesces, and double-dealing proliferates. The mortgage system breaks down.Other problems in exogenous finance are legion. Credit means debt. It also means patronage, at international, national, or local levels. Neither public nor private financial institutions have overcome the great cultural, political, or pragmatic difficulties of lending to small farmers for staple food cropping or most other farm activities. These people have important debts and obligations of their own already, some quite subtle and some long-term. The promise of more loans, the most commonly cited justification for freehold tenure, proves largely illusory in western Kenya, as in many other rural parts of tropical Africa. Aid strategies based on saving and investment, and on non-financial intervention, hold more promise.RésuméCeux qui ont établi la planification agricole ont assumé de facon générate que, pour adopter les nouvelles cultures et ressources, les fermiers à petite échelle ont besoin de prêts financiers, et que le titre de propriétaire leur permet d'emprunter en constituant une sorte d'engagement pour une hypothéque. L'exemple du peuple Luo de plus de deux millions et des autres au Kenya, montre que cette théorie n'est pas due tout appropriee dans le contexte d'une Afrique tropicale.En raison d'un systeme foncier basé sue l'héritage père-fils, le recueillement des belles-families, et d'autres principes, les Luo ont tendance à vivre en communaute familiale. Us continuent à justifier leurs demandes de terres essentiellement par leur travail effectué, par la présence des tombes ancestrales, et par l'appartenance au groupe que celles-ci représentent. Ces modèles persistent, même depuis que le gouvemement a attribué des titres de propriété individuels à partir des années 1950. Les institutions financières qui tentent de saisir les débiteurs, et les acheteurs qui essaient de prendre possession de ces terres, se heurtent à une résistance ferme à la fois sociale et politique, et parfois même violente. Le registre des terres du gouvemement tombe en désuetude, et le procédé du double-jeu prolifère. Le système de l'emprunt s'effondre.Les autres problèmes en finance exogène sont multiples. Le credit est un signe de dette. II signifie aussi le patronage, aux niveaux international, national, ou local. Aucunes institutions financières publiques ou privées n'ont pu surmonter les grandes difficultés culturelles, politiques ou pragmatiques pour prêter à de petits fermiers pour la production alimentaire de base ou la plupart des autres activités de la ferme. Ces gens ont déjà leurs propres dettes de reconnaissance, à plus ou moins long terme. La promesse d'emprunts supplémentaires, ce qui est le plus regulièrement utilisé pour justifier la propriété fonciére libre, se revèle être fortement illusoire dans le Kenya de l'ouest, comme dans beaucoup d'autres régions de l'Afrique tropicale. Les stratégies d'aides basées sur l'épargne et l'investissement, ainsi que sur des interventions non financieres donnent plus d'espérances.

It is unequivocal that the poor condition of South Australia’s terrestrial biodiversity is continuing to decline overall – much like elsewhere in Australia. This decline is mainly due to the legacy of vegetation clearing and habitat modification since European colonisation, the destructive influence of invasive species (especially predators like cats and foxes) on its native fauna and flora, and impotent or broken legislation to prevent further damage. The struggle to maintain our remaining biodiversity, and our intentions to restore once-healthy ecosystems, are rendered even more difficult by the added influence of rapid climate disruption. Despite the pessimistic outlook, South Australians have successfully employed several effective conservation mechanisms, including increasing the coverage of our network of protected areas, doing ecological restoration projects, reducing the densities of feral animals across landscapes, encouraging private landholders to protect their biodiversity assets, releasing environmental water flows to rivers and wetlands, and bringing more people in touch with nature. While these strategies are certainly stepping in the right direction, our policies and conservation targets have been hampered by arbitrary baselines, a lack of cohesion among projects and associated legislation, unrepresentative protected areas, and inappropriate spatial and time scales of intervention. While the challenges are many, there are several tractable and affordable actions that can be taken immediately to improve the prospect of the State’s biodiversity into the near future. These include coordinating existing and promoting broader-scale ecological restoration projects, establishing strategic and evidence-based control of invasive species, planning more representative protected-area networks that are managed effectively for conservation outcomes, fixing broken environmental legislation, avoiding or severely limiting biodiversity-offset incentives, expanding conservation covenants on private land, coordinating a state-wide monitoring network and protocol that tells the South Australian community how effective we are with our policies and actions, expanding existing conservation investment and tapping into different funding schemes, and coordinating better communication and interaction among government and non-governmental environment agencies. Having a more transparent and defensible link between specific conservation actions and targeted outcomes will also likely improve confidence that conservation investments are well-spent. With just a little more effort, coordination, funding, and foresight, South Australia has the opportunity to become a pillar of biodiversity conservation.
