Messages for Rio

Sustainability is Essential for Development

Interview with Stephan Opitz, Director General of KfW, on the Rio+20 conference and the work of KfW. On the occasion of the UN-conference Rio+20 he explains how Germany’s promotional bank implements this task. KfW promotes sustainable projects and programmes in developing and transition countries in areas such as water supply, food security and energy and is in this way supporting a “green economy” in its partner countries.

Issue Brief

Economics of Land Degradation – The Costs of Action versus Inaction

In recent years, prices of agricultural land have increased quickly, actually doubling and tripling in many parts of the world. This land value reassessment has been prompted by rising crop prices and perceived land scarcity. But even as the value of land rises, land degradation continues and investments to prevent it are lagging. Awareness of environmental risks has moved to the forefront of global consciousness during the past 25 years. However, this awareness has not translated into comprehensive action to address the problem of land degradation, which poses a serious threat to long-term food security. This inaction is primarily the result of limited knowedge of the costs related to land degradation and of insufficient institutional support. Policy action and research are needed to resolve this paradox of high-value land and low levels of investment. – by Ephraim Nkonya, Nicolas Gerber, Joachim von Braun, and Alex De Pinto

With the global population increasing and our climate changing, now more than ever we need to halt the overexploitation of natural resources which supply us with water, energy and food, and manage these resources sustainably. For smallholder farmers across the developing world, this need is perhaps most critical, for without a secure food supply, access to clean water and sources of energy, their livelihoods are threatened. - By Kate Langford.

No Wars for Water - Why Climate Change Has Not Led to Conflict

In short, predictions of a Water World War are overwrought. However, tensions over water usage can still exacerbate other existing regional conflicts. Climate change is expected to intensify droughts, floods, and other extreme weather conditions that jeopardize freshwater quantity and quality and therefore act as a threat-multiplier, making shaky regions shakier -by

“Better Land, Water Management Needed to Fight Hunger,” Group Says

Smarter use of land, water and energy is needed for the world to continue to make gains against hunger, the International Food Policy Research Institute said today as it released its annual Global Hunger Index. The gauge shows 20 countries with levels of hunger that are “extremely alarming” or “alarming,” down from 26 last year and 43 in 1990 when the institute began compiling the index. Burundi, Eritrea and Haiti scored the worst, while the Democratic Republic of Congo, a perennial poor performer, didn’t have enough data to be ranked. The bulk of low-scoring countries are in sub-Saharan Africa and South Asia.

Sustainable agriculture needs integrated solutions

In its RIO+20 Call-to-action, CGIAR called for “adopting cross-sectoral approaches which facilitate broader partnerships, coordinated regulatory frameworks and appropriate economic incentives. We need the vision and courage to transcend conventional sectoral approaches and apply integrated thinking to the management of agriculture, aquaculture, livestock, forests and water.” AlertNET wanted to find out more, and talked to Stephen Hall (Director General, WorldFish Center), Papa Seck (Director General, Africa Rice Center), Tony Simons (Director General, World Agroforestry Centre), Alain Vidal (Director, Challenge Program on Water and Food – CPWF), Amy Duchelle (Research Fellow, Center for International Forestry Research - CIFOR) and from the International Institute of Tropical Agriculture - IITA), we have Peter Neuenschwander (Scientist Emeritus) and Piet van Asten (Systems Agronomist).

Solar Energy Brings Food, Water, and Light to West Africa

It’s long been established doctrine in international development circles that diesel engines are the most cost-effective tools for pumping water and powering villages. But Robert Freling has been turning that doctrine on its head. The executive director of the Washington-based Solar Electric Light Fund (SELF), Freling has proven that solar power can be more economical than internal combustion engines, if the cost-benefit analysis looks beyond the short term.

World Water Day Message: Integrated thinking to address water and food security challenges

“The WFE nexus is an approach to balance development priorities in a more integrated manner. The approach supports a transition to sustainability, by reducing trade-offs and generating additional benefits that outweigh the transaction costs associated with stronger integration across sectors,” write Alain Vidal

Bessere Wassernutzung könnte Ernten verdoppeln

Trockenheiten führen immer wieder zu Hungersnöten - doch Wassermangel ist offenbar in vielen Fällen nicht das Hauptproblem. Forscher kommen in einer Studie zu dem Ergebnis, dass eine effiziente Wassernutzung die Nahrungsproduktion in vielen Weltregionen deutlich steigern könnte.
