Pakistan Relief Toolkit: Providing Essential Knowledge and Resources for Relief Efforts

As the flood waters begin to recede across Pakistan, Prime Minister Yousuf Raza Gilani says the government is now “seriously concerned” about the potential spread of epidemic diseases.

The flooding has left more than 1,600 people dead and approximately six million homeless. According to the BBC, about 17 million of Pakistan’s 166 million people have been affected by the disaster. In addition, the United Nations warns that without enough doctors or proper facilities, over 100,000 pregnant women are now at risk of infection and disease.

“As human misery continues to mount, we are seriously concerned with the spread of epidemic diseases,” Yousuf Raza Gilani said, adding, “There is a likelihood of water-borne diseases such as cholera, diarrhea and dysentery, especially in children who are already weak and vulnerable.”

ICT for Youth empowerment

The world today is faced with several challenges like the economic recession, climatic change, disease outbreaks, increased organized crime, information explosion, and uncontrolled migration. Like any other calamity, the harsh effects are mostly felt by the vulnerable third world states. Zimbabwe, coming out of an economic crisis characterized by record inflation, high unemployment, heavy brain drain and a large reduction in the Gross Domestic Product, has plenty to do with regards to enhancing the recovery path and rejuvenating the economy. With the Unity government having managed to tame the legendary inflation and the economy expected to grow, focus is now on which sectors of development should be prioritized over others given a background of an economy thriving on limited resources.

Restoring lives and landscapes

Group Resource

This booklet tells the story of a project that has had a profound influence on the management of four large forest areas in Guinea. The Landscape Management for Improved Livelihoods (LAMIL) project has also done much to improve the welfare of local people. Indeed, the two - better forest management and improved livelihoods - are inextricably linked.

The World Agroforestry Centre, the Center for International Forestry Research (CIFOR) and their partners in the LAMIL project have developed a system of co-management, involving local communities and government agencies, which is generating considerable interest in Guinea and throughout the region.

Not long ago, these forests were managed by government agencies. Local people were forbidden from using them. As a result, the forests were widely abused, and the authorities were able to do little to stem the tide of illegal logging, poaching and land

The water debate

Group Discussion Topic

Water is vital to life. It is the essential component in all aspects and activities related to our well-being and existence – including food and energy production and manufacturing in general. It’s clear that if our water supply continues to dwindle, and/or, if water became unaffordable, our lives would be detrimentally transformed. Billions of people are already experiencing and suffering from the mismanagement and unequal allocation of water. Between 1.1 and 1.5 billion people in the world lack access to safe drinking water and 2.6 billion people lack access to basic sanitation. 2.2 million people die each year due to low quality drinking water and/or lack of sanitation – that is 42,000 people per week, 90 percent of whom are children (WHO/UNICET:2005). Exclusion to socially necessary goods and services such as fresh water has horrific consequences that are catastrophic, yet entirely preventable.

GM Crop Information

Group Resource

When GM crops and foods were first introduced in the late 1990s, some scientists raised concerns that genetic modification was imprecise and unpredictable and could result in harm to health and the environment. They warned that:

  • GM could create foods that are toxic, allergenic and less nutritious than their non-GM counterparts

  • GM crops could damage vulnerable wild plant and animal populations
  • GM plants cannot be recalled, but as living organisms will propagate, transmitting any damaging properties from generation to generation
  • GM crops could cause irreversible alterations to the food supply, with serious consequences for the environment and human and animal health.

Risk analysis of genetically engineered plants

Group Resource

A report by Testbiotech e.V. Institute for Independent Impact Assessment in Biotechnology
Authors: Christoph Then, Christof Potthof October 2009

Summary points compiled by GMWatch

GM food safety testing

  • European Food Safety Authority's (EFSA) concept of risk assessment of genetically modified (GM) plants is essentially based upon guidelines that were developed by the OECD (Organisation for Economic Co-operation and Development) as early as 1993 on the assumption that the risks posed by GM plants are the same as those posed by conventional plants.

  • But the differences between conventional breeding and genetic engineering of plants are becoming clearer in the light of current genome research. Experience gained from conventional breeding cannot be applied to GM plants.
  • Changes in the activity of plant genes in the genetic engineering process are not an expression of natural gene regulation but an indication of disruption.

Generic guidelines for mainstreaming drylands issues into National Development Frameworks

Group Resource

The Generic Drylands Mainstreaming Guidelines have been developed by the UNDP-DDC in close collaboration with the UNEP and UNDP/Global Environment Facility (GEF) Global Support Unit. This document provides broad generic steps for mainstreaming environment and drylands issues into national development frameworks, as well lessons drawn from various countries on environment and drylands mainstreaming.

Institutionalizing Evaluation - review of international experience

Group Resource

Policy-makers are experimenting with billion’s of people’s lives on a daily basis without informed consent, and without rigorous evidence that what they do works, has no substantive adverse effects, and could not be achieved more efficiently through other means. In this context, carefully designed and implemented evaluations have the potential to save lives and improve people’s welfare. However, to date evaluations have tended to be selected based on the availability of data, the interest of researchers and donors, and the availability of funds rather than on their potential contribution to broader development strategies. For this reason, the institutionalization of quality evaluation is necessary in order to turn it into an optimal tool for policy-making. This report looks at the experiences of institutionalizing government evaluation efforts and considers the lessons learnt for countries starting down that road.

Dryland opportunities - A new paradigm for people, ecosystems and development

Group Resource

Drylands cover 41 percent of the earth’s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.

Africa's Development in a Changing Climate

Group Resource

Key policy advice from World Development Report 2010 and Making Development Climate Resilient: A World Bank Strategy for
Sub-Saharan Africa - Act Now, Act Together, Act Differently

"Over the past ten years, Sub-Saharan Africa has made a great deal of progress in terms of economic growth. In fact, Africa has the potential to emerge as an exciting new center of growth in the evolving global economy. However, to continue on an accelerated growth path, the region needs to tackle climate variability and climate change, which now pose a daunting risk to growth, development, and poverty reduction. Climate is hardly a new factor in the region's history, but with global warming, Africa's vulnerability is deepening, making it the most exposed region in the world to the impacts of climate change. The hard-won progress of recent years could be reversed with extreme weather, crop failures, and outbreaks of hunger and disease."

Climate change, population pressure and conflict in South Africa

Group Resource

Climate change presents humanity with its largest challenge in recorded history. Its predicted eff ects over the coming decades include extreme weather events, droughts, fl ooding, rising sea levels that could affect countries such as Nigeria and Mozambique, retreating glaciers (although not in Africa, but with global impact), changes in habitats and increased spread of life-threatening diseases such as malaria.

Little concrete analysis has been published on the relationship between climate change and conflict, however, and even less on the potential role that population growth plays in intensifying that pressure.

Climate change and AIDS: A joint working paper

Group Resource

AIDS and climate change (CC) are two of the most important "long wave" global issues of the recent past, the present and the future. They share similarities, interactions, and present possibilities for a more united response. Yet these links have received little analysis. This paper seeks to address that gap. It first focuses on scientific issues, identifying major, minor, and speculative pathways by which AIDS and CC are likely to interact. These interactions are, here, called the HIV and Climate Change Complex (HACC).

Farm ponds for water, fish and livelihoods

Group Resource

Aquaculture has been recognized as an important component of rural development, aimed at improving food supply and generating more income for poor farming households. Ponds add value to farming activities: water from ponds can serve
domestic and livestock water supplies as well as irrigation for crops. Raising fish is an obvious use for a farm pond; it adds value to the water and provides improved nutrition for farm families. Smallholder farms ponds can be viable and sustainable
enterprises with appropriate targeted assistance. Planned and implemented interventions can facilitate assistance that makes farmers self-reliant rather than dependent on the public sector, NGOs and donors. The benefits can be:

  • organised and better informed farmers

Rainwater harvesting: a lifeline for human well-being

Group Resource

The aim of this report is to compile a synthesis of experiences that can provide insight into the multiple opportunities rainwater harvesting can have when addressing human well-being, while continuing to sustain a range of ecosystem services. This synthesis of linkages between ecosystem services, human well-being and rainwater harvesting interventions examines 29 cases from diverse economic and environmental settings.

Water supply of the right quality and quantity is essential for productive ecosystems and human well-being. The increasing demand on water resources for development whilst maintaining healthy ecosystems puts water resources under pressure.

Water resources, climate change and human vulnerability

Group Resource

This paper focuses on the impact of climate change on water resources and the affect it has on human society. Millions of people are at risk from the impacts of climate change associated with the socio-political dimensions of global change and demographic changes.

A model to link the climate and social sciences is developed in a policy-oriented approach to make a holistic assessment of human vulnerability to climate and other drivers of social change. The Climate Vulnerability Index (CVI) uses water as a focus as it is a key factor of human and ecological well-being. Though it is not a new concept, it has been developed to encompass variations within countries and it is not limited to specific communities.

Assessing the costs of adaptation to climate change: A review of the UNFCCC and other recent estimates

Group Resource

The publication warns that the UN negotiations aimed at tackling climate change are based on substantial underestimates of what it will cost to adapt to its impacts. The real costs of adaptation are likely to be 2-3 times greater than estimates made by the UN Framework Convention on Climate Change (UNFCCC). Professor Martin Parry, a former co-chair of the Intergovernmental Panel on Climate Change and his co-authors look at the estimates from a range of perspectives, and conclude that:

  • the current cost assessments do not include some key sectors, such as ecosystems, energy, manufacturing, retailing, and tourism

  • some of the sectors included have been only partially covered in cost estimates

Climate change and water

Group Resource

"Climate change challenges the traditional assumption that past hydrological experience provides a good guide to future conditions. The consequences of climate change may alter the reliability of current water management systems and
water-related infrastructure. While quantitative projections of changes in precipitation, river flows and water levels at the
river-basin scale are uncertain, it is very likely that hydrological characteristics will change in the future. Adaptation procedures
and risk management practices that incorporate projected hydrological changes with related uncertainties are being developed in some countries and regions."

Ecosystem-based Approaches to Climate Change

Group Resource

"The World Bank’s mission is to alleviate poverty and support sustainable development. Climate change is a serious environmental challenge that could undermine these goals. Since the Industrial Revolution, the mean surface temperature of Earth has increased an average 2° Celsius due to the accumulation of greenhouse gases in the atmosphere. Most of this change has occurred in the past 30 to 40 years, and the rate of increase is accelerating. These rising temperatures will have significant impacts at a global scale and at local and regional levels. While it remains important to reduce greenhouse gas emissions and reverse climate change in the long run, many of the impacts of climate change are already in evidence.

Climate and Cultural Change in West Central Africa (Cameroon and Gabon) over the last 5,000 years - Dr. OSLISLY  Richard

KMAfrica2009 Dakar Conference Paper

The current distribution of tropical rain forest in Central Africa corresponds to a single point in a long history of climate change covering several millennia. Since 3,000 BC the region has been strongly influenced by humid and dry climatic phases and shifts in human demography (Bantu migrations) and technology. Through this period West Central Africa has seen three major climatic phases:

  • A humid episode characterized by forest expansion from 9,000 to 1,500 BC

  • A warm, dry episode from 1,500 BC to 600 AD during which the forest block was fragmented with important spaces opened of savanna
  • The return of humid conditions since 600 AD resulting in a new phase of forest expansion
  • During this period Stone Age hunter gatherers were replaced around 2,000 BC by sedentary Neolithic peoples who were, in turn, replaced by iron working peoples around 500 BC.
