Pervasive threats of climate change and land degradation have compounded the inherent low farm productivity problem in sub‐Saharan Africa. Though sustainable agricultural intensification practices have been shown to improve the resilience of farm production in the face of these emerging threats, they suffer low adoption rates typical of any technology adoption in these regions. Recent evidence points to an emergence of large traders in smallholder grain markets of countries in sub‐Saharan Africa.

The city of Cape Town suffered a severe water crisis in 2018. At the peak of the drought in South Africa's Western Cape, a randomized control trial at 105 schools investigated the impact of two behavioral interventions to encourage responsible water usage: detailed water usage data feedback from smart meters, and an interschool competition.

Climate forecasting is a crucial tool for managing risks in climate-sensitive economic sectors like agriculture. Although rainfed subsistence farming dominates livelihoods in Africa, information on access, integration in farm decisions and impact of improved seasonal climate forecasting remains scanty. This paper addresses this gap using representative data of 653 households across three regions in North-Central Namibia.

With many species predicted to respond to a changing climate by shifting their distribution to climatically suitable areas, the effectiveness of static protected areas (PAs) is in question. The Madagascan PA network area has quadrupled over the past 15 years, and, although conservation planning techniques were employed to prioritise suitable areas for protection during this process, climate change impacts were not considered.

Climate change could potential have significant impacts on the global tourism industry through changes in accessibility, comfort levels, and geographic or seasonal changes to attractions. Global and regional studies based on climate indices suggest that there will be global shifts in tourism, with many of the currently warmer areas potentially experiencing decreases in tourism. These include much of the global south, where nature-based tourism is both an important contributor to economic output and believed to be vulnerable to climate change.

The natural conservation of coastal lagoons is important not only for their ecological importance, but also because of the valuable ecosystem services they provide for human welfare and wellbeing. Coastal lagoons are shallow semi-enclosed systems that support important habitats such as wetlands, mangroves, salt-marshes and seagrass meadows, as well as a rich biodiversity. Coastal lagoons are also complex social-ecological systems with ecosystem services that provide livelihoods, wellbeing and welfare to humans.

AbstractClimate change is having a significant impact on the biology and ecology of fish stocks and aquaculture species and will affect the productivity within seafood supply chains in the future. The challenges are further amplified when actors within the fisheries and aquaculture sectors have very different ideas and assumptions about climate change and what risks and opportunities they entail. In order to address the challenges of climate change, several countries have developed national adaptation plans.

Using experiments in which participants play the role of polluting firms, we study compliance behavior with emissions limits under two types of fines and two different regulatory instruments. We find that the market price of pollution permits and the probability of violating permits holdings are higher with a fine that is convex in the level of violation than with one that is linear. This effect operates through an increase in the prices asked by sellers, not in the bids made by the buyers of permits.
