Using Namibia as a case study, IIED has begun a programme attempting to quantify the adverse economic impacts that climate change is having on developing countries.The article highlights initial conclusions from their study of Namibia which found that climate change is likely to exacerbate the dry conditions already experienced in southern Africa with rainfall, when it does come, being in bursts of greater intensity leading to erosion and flood damage. Poverty implications for rural communities will be acute.

In many areas of Africa, rural livelihoods depend heavily on subsistence farming. Using improved agricultural technologies can increase productivity in smallholder agriculture and thus raise household income and reduce poverty. Data from a nationally representative rural household survey from 2005 is used to assess the impact of four technologies - improved maize seeds, improved granaries, tractor mechanization, and animal traction - on household income in Mozambique.

A system for highly precise navigation uses visual and inertial- based measurements that feeds into a unique Kalman filter based algorithm for pose estimation (position and orientation). The pose estimation algorithm can provide a unified basis for stability control traction control slip detection and obstacle avoidance in ground-based applications and navigation and tracking in air-based applications. The system operates where GPS and odometer systems fail or are denied and can be integrated into existing automatic active safety systems and aerospace navigation systems.

Technology
Background: Variable frequency inverter drive systems are being used more often for driving electrical machines; these are of particular importance for driving large industrial motors and traction motors for vehicles. However traditional variable frequency drives are limited by high device voltage ratings and poor output waveform quality. Thus multilevel inverters have been considered for such applications because of their improved long-term reliability reduced size improved performance and lower cost.

This is the use of traction to drive dynamo to charge batteriesenergy conversion from rotary motion to electrical energy. The traction due to rotation of the wheel is tapped by use of a dynamo which converts this rotational motion to electrical energy(dc) This is then used to charge lead acid accumulators.

Publication dateObjectiveApproach
The idea of climate compatible development is intuitively attractive, and has gained widespread traction since it was first proposed it in 2010. It is now an idea that has become central to the new Sustainable Development Goals (SDGs). The global goals are transformative in scope precisely because they require action on climate change to be mainstreamed in all aspects of development work.

This publication is the abridged version of the report ‘Strategies for mitigating climate change in agriculture: recommendations for philanthropy’. The report was designed to identify greenhouse gas (GHG) mitigation options in the agricultural sector. It provides a snapshot of the global mitigation potential in the year 2030, compared to a hypothetical baseline in which no additional mitigation from agriculture is attempted, beyond current adoption and intensification trends.

Publication dateObjective
Food exporters are increasingly being asked by retailers to measure and reduce the greenhouse gas (GHG) emissions of their products, and new market requirements have emerged, mainly in the form of standards on ‘product carbon footprinting’ (PCFs). The current paper indicates that PCF standards have gained significant traction in the agri-food sector, and they can create new potential opportunities for exporters in the transition to a green economy. The paper introduces the following findings:
