Burundi’s economy is dominated by small-scale agriculture practiced on the slopes of hills and mountains. The burgeoning population and an overwhelming reliance on natural resources by 90 percent of the population have both caused aggravated environmental degradation. The recent World Bank Country Environment Analysis estimates that each year, almost 38 million tons of soil is lost and land degradation cost 4% of the country’s GDP. Soil erosion worsens Burundi’s socioeconomic situation, and particularly affects the poorest.

Our new feature film from Roy Maconachie and Simon Wharf explores the pathway of a diamond from mine to market, and asks the question, who really benefits?

The residents of the Ganges and Mekong River deltas face serious challenges from rising sea levels, saltwater intrusion, pollution from upstream sources, growing populations, and infrastructure that no longer works as planned. In both deltas, scientists working for nearly two decades with communities, local governments and nongovernmental organizations (NGOs) have demonstrated the potential to overcome these challenges and substantially improve people’s livelihoods.

Mobilising under-utilised low carbon (ULC) land for future agricultural expansion helps minimising further carbon stock loss. This study examined the regency cases in Kalimantan, a carbon loss hotspot, to understand the key factors for mobilising ULC land via narrative interviews with a range of land-use actors and complementary desktop analyses.

This paper develops a framework for improved mainstreaming of ecosystem science in policy and decision-making within a spatial planning context. Ecosystem science is advanced as a collective umbrella to capture a body of work and approaches rooted in social-ecological systems thinking, spawning a distinctive ecosystem terminology: ecosystem approach, ecosystem services, ecosystem services framework and natural capital.

Where rights over natural resources are contested, the effectiveness of conservation may be undermined and it can be difficult to estimate the welfare impacts of conservation restrictions on local people. In particular, researchers face the dilemma of estimating respondents’ Willingness To Pay (WTP) for rights to resources, or their Willingness To Accept (WTA) compensation for foregoing these rights.

Forest conversion in the tropics is increasingly driven by global demand for agricultural forest-risk commodities such as soy, beef, palm oil and timber. In order to be effective, future forest conservation policies should include measures targeting both producers (the supply side) and consumers (the demand side) to address commodity-driven deforestation.

Cameroon is part of a global trend towards large-scale investments in infrastructure, agriculture, extractive industries, industrial facilities and real estate that are displacing many people. Deeming these projects in the public interest, governments often acquire land by expropriating locally-held land rights. But compulsory land acquisition has severe economic, social and cultural impacts for families and communities.

Conservation easements offer sustainable land use and environmental conservation through land use restrictions. Opportunities exist to improve the efficiency by which parties interested in conservation easement transactions are matched, which may contribute to the overall protection of agricultural landscapes. This study utilizes stated choice questions to elicit preferences for conservation easements by both landowners, as potential easement suppliers, and land trust professionals as potential easement demanders.

The relationship between sustainable urban development and environmental sustainability is crucial to every strategy of urban transformation, renewal and regeneration. In particular, urban regeneration entails programmes of urban transformation that involve the rehabilitation of existing parts of a city, re-use previously built-up area and abandoned buildings, and redevelop blighted urban spaces to increase urban sustainability.

Land change in Kigali, Rwanda, is examined using Intensity Analysis, which measures the temporal stationarity of changes among categories. Maps for 1981, 2002 and 2014 were produced that show the land categories Built, Vegetated and Other, which is composed mainly of croplands and bare surfaces. Land change accelerated from the first time interval (1981–2002) to the second time interval (2002–2014), as increased human and economic activities drove land transformation.
