Policies developed at national levels can be unresponsive to local needs. Often they do not provide the rural poor with access to the assets and services they need to allow them to innovate and adapt to the ways that increased climate variability and change exacerbate challenges to basic securities – food, water, energy, and well-being. In development deficit circumstances, common pool resources are important for climate adaptation purposes. In order for climate adaptation actions to deliver resilience, local perspectives and knowledge need to be recognised and given due priority in formal planning systems. Basing formal adaptive development planning on local strategies can support and strengthen measures that people have been tested and know to work. Local climate adaptation through collective action can address current increases in climate variability, future incremental changes, and the need to transform existing systems to deal with qualitative shifts in climate. These types of adaptation can work in cumulative ways. The results of local adaptation collective action that have benefits of low rivalry between users while being highly inclusive can be considered “local public goods”. Evidence is beginning to emerge that when local governance systems facilitate high levels of participation in planning collective action for climate adaptation, and direct access to resources for implementing local plans, “local public goods” can be created and common pool resources better managed.  相似文献

To understand resilience to climate and environmental changes in fragile and conflict-affected societies is particularly important but equally challenging. In this paper, we first develop a conceptual framework to explore the climate-fragility-conflict and climate-resilience-peace nexus. Second, we discuss approaches to promote pathways from climatic changes to peace. We draw on the relevant literature and International Alert's experience in fragile and conflict-affected societies to stress the key role of resilience. To build resilience, climate, development, peacebuilding, and government actors would have to overcome bureaucratic and institutional barriers and cooperate across thematic and regional silos.  相似文献

Over the past few decades home garden research has emphasised the promotion of home gardening for nutritional and other welfare benefits for the poor in urban areas. Still, the urban communities who cultivate plants in their home gardens are in general represented as rather uniform groups, and no distinction is made in terms of caste, ethnic groups, or social class. This article asserts that social stratification represents an important aspect that needs to be taken into account while devising educational programmes and community projects for the promotion of home herbal gardens in urban areas.  相似文献

This article aims to provide knowledge and practical guidance to managing and implementing within the framework of endogenous development. The paper gives a theoretical overview of endogenous development, linked to issues of globalisation and poverty, and ongoing work among European institutions and academics that suggest shifts in Europe from exogenous to endogenous development approaches. It then makes a case for a paradigm shift – an African alternative to modernisation and development, namely endogenous development – using experiences with two NGOs in Ghana and Zimbabwe to locate theory in practice. The paper concludes with some empirical pre-requisites for conducting endogenous development with rural communities.

This article is prompted by the requests of my students at the University for Development Studies, Ghana, for knowledge and information, and practical guidance to managing and implementing within the framework of endogenous development. I start by giving a theoretical overview of the concept of endogenous development and link it with current issues of globalisation and poverty. I briefly mention current work among European institutions and academics that suggest shifts in Europe from exogenous to endogenous development approaches. Encouraged by such developments, I then make a case for a paradigm shift – an African alternative to modernisation and development, endogenous development. I bring to light the experiences with endogenous development in two NGOs – CECIK (Ghana) and AZTREC (Zimbabwe) – in order to locate theory in practice (praxis). I conclude by providing some empirical prerequisites for conducting endogenous development with rural communities, which demonstrate one way of conducting experimentation with farmers within the context of endogenous development.  相似文献

We are the middle of a global identity crisis. New notions of identity are made possible in the online world where people eagerly share their personal data and leave ‘digital footprints’. Multiple, partial identities emerge distributed across cyberspace divorced from the physical person. The representation of personal characteristics in data sets, together with developing technologies and systems for identity management, in turn change how we are identified. Trustworthy means of electronic identification is now a key issue for business, governments and individuals in the fight against online identity crime. Yet, along with the increasing economic value of digital identity, there are also risks of identity misuse by organisations that mine large data sets for commercial purposes and in some cases by governments. Data proliferation and the non-transparency of processing practices make it impossible for the individual to track and police their use. Potential risks encompass not only threats to our privacy, but also knowledge-engineering that can falsify digital profiles attributed to us with harmful consequences. This panel session will address some of the big challenges around identity in the digital age and what they mean for policy and law (its regulation and protection). Questions for discussion include: What does identity mean today? What types of legal solutions are fit for purpose to protect modern identity interests? What rights, obligations and responsibilities should be associated with our digital identities? Should identity management be regulated and who should be held liable and for what? What should be the role of private and public sectors in identity assurance schemes? What are the global drivers of identity policies? How can due process be ensured where automated technologies affect the rights and concerns of citizens? How can individuals be more empowered to control their identity data and give informed consent to its use? How are biometrics and location-tracking devices used in body surveillance changing the identity landscape?  相似文献

Bytewise approximate matching is a relatively new area within digital forensics, but its importance is growing quickly as practitioners are looking for fast methods to screen and analyze the increasing amounts of data in forensic investigations. The essential idea is to complement the use of cryptographic hash functions to detect data objects with bytewise identical representation with the capability to find objects with bytewise similar representations.Unlike cryptographic hash functions, which have been studied and tested for a long time, approximate matching ones are still in their early development stages and evaluation methodology is still evolving. Broadly, prior approaches have used either a human in the loop to manually evaluate the goodness of similarity matches on real world data, or controlled (pseudo-random) data to perform automated evaluation.This work's contribution is to introduce automated approximate matching evaluation on real data by relating approximate matching results to the longest common substring (LCS). Specifically, we introduce a computationally efficient LCS approximation and use it to obtain ground truth on the t5 set. Using the results, we evaluate three existing approximate matching schemes relative to LCS and analyze their performance.  相似文献

数字内容交易目前在全球数字化背景下蓬勃发展,其中,有关数字内容的瑕疵担保责任问题备受关注;立法上欧盟在新出台的《有关提供数字内容和服务的合同交易指令》中有三个条款对此作了专门规定,同时,德国也将此规定完全予以转化适用。基于现有欧盟背景下德国法有关数字内容瑕疵担保责任的比较分析,可知其不但能准确认定数字内容交易中的瑕疵形态与有效提供救济,而且有助于消费者保护。根据我国现有一般物之瑕疵担保规定并结合我国民法典编纂以及域外法经验,在解释论上,通过相关类案的比较分析,我国就此有借鉴适用的必要性;在立法论上,今后在我国《民法典》的解释与适用过程中,可先在《民法典(合同编)》司法解释中原则性地规定有关数字内容瑕疵担保责任,再另行制定具有针对性的单行法,从而有助于数字时代的我国消费者保护与数字经济发展。  相似文献

Given the size and complexity of many digital forensic science device examinations, there is a need for practitioners to formally and strategically determine a course of conduct which allows them to undertake the most robust and efficient examination possible. This work outlines both the need for practitioners to have a digital evidence strategy (DES) when tackling any given examination scenario, how to construct one and the concerns which exist when no formal DES is in place. Approaches to DES development are examined and the context to which they should be deployed are analysed, with focus being on the use of DESs at the examination/processing stage of the investigative workflow. Finally, a ‘DES skeleton’ is offered to guide practitioners as they seek to create their own DES.  相似文献

This article investigates gender dimensions of decision-making on access to, and control over, productive assets for agricultural development in selected communities in Ghana. The men were more educated, resourced, and economically empowered than the women. This resulted in differential access to, and control over, resources by gender and a low level of female participation in decision-making. The study identified a land access gap by gender and crop acreage gap of up to 80% for women as compared to men. Challenges limiting women in agricultural production and processing include inadequate land access, inadequate capital, inefficient processing technologies, and unattractive markets.  相似文献
