Temperature at Roque de los Muchachos Observatory rose 1.1 degrees C in 20 years — twice as much as predicted by climate models

The meteorological data recorded over the past two decades by sensors of the Roque de los Muchachos astronomical observatory facilities point to a rise of 1.1 C in the average temperature. The analysis shows more than double the increase predicted by climate models for the same area, and even more than expected for the next

Reversing Environmental Decline: Key Lessons from African Communities for Global Sustainability

In the countryside of Africa, many people’s lives are closely linked to the land they cultivate. However, environmental degradation is a significant danger to both the natural surroundings and the health of these communities. Recent studies have identified strategies for addressing the intertwined issues of land degradation and poverty.Environmental damage presents a significant risk to ecosystems and human health. A recent study from Stanford University and the French Agricultural Research Centre for International Development (CIRAD) examines how different African communities have worked to combat this issue, providing important findings on effective strategies. Published on October 30 in Sustainability Science, the research highlights the necessity of ongoing partnerships among local communities, governmental bodies, and organizations to promote sustainable practices.

The researchers caution against applying a uniform solution across all areas due to their unique circumstances.

According to Eric Lambin, a co-author of the study and a prominent professor at the Stanford Doerr School of Sustainability, it is crucial to create an effective environmental policy by learning from historical experiences that highlight successful strategies for reversing environmental damage.

Restoring the Environment

African communities have long struggled with two main issues: combating environmental degradation and enhancing the quality of life for their residents. The decline in land productivity caused by factors such as inadequate soil nutrients, deforestation, or climate change has made these challenges even more pressing.

As climate change progresses, communities are feeling increasing pressure. Researchers Lambin and Camille Jahel from CIRAD highlight that this issue is closely tied to a history of colonialism, where authorities restricted access to natural resources and propagated a narrative of over-exploitation. This has resulted in top-down restoration initiatives that frequently yield limited outcomes.

In recent times, various regions have embarked on new strategies to counteract these adverse trends, often receiving backing from governments, NGOs, or international organizations. However, the outcomes have been inconsistent.

Several initiatives have led to notable improvements, while others did not meet expectations.

In a review of 17 cases from 13 African countries aimed at combating land degradation, researchers identified common traits among successful projects. A crucial element is strong social connections among participants, backed by effective institutions. For example, in Tanzania’s Shinyanga region, where nearly 90% of the community took part in reforestation activities, significant progress was made. This effort resulted in the restoration of between 300,000 and 500,000 hectares—approximately 1,100 to 1.

Covering an area of 900 square miles, the forest provided essential resources like wood for fuel, improving local livelihoods.

An essential aspect is ensuring that incentives align with environmental objectives. For instance, in Burkina Faso, farmers started cultivating cashew trees motivated by the chance to sell their products in global markets. This not only created a new source of income but also played a role in fighting desertification through increased tree planting. These examples emphasize the necessity of integrating economic and social needs into environmental restoration initiatives.

 

According to Jahel, a research fellow at CIRAD, the motivations for restoration were primarily economic, but there were also concerns regarding land security and enhanced ecosystem services following the recovery of natural resources. Jahel received funding from the Stanford France-Stanford Center for Interdisciplinary Studies for a joint research initiative with the Stanford Woods Institute for the Environment during this study.

Encouraging Restoration Efforts

The research highlights that beyond local partnerships, external support is crucial. This includes providing resources and technical help, which have been significant factors in many successful restoration projects.

In regions like Niger and Burkina Faso, non-governmental organizations (NGOs) and government bodies played a crucial role by providing essential tools, knowledge, and financial resources to initiate various projects. This outside assistance was particularly important during the initial phases of these efforts, helping to minimize risks associated with implementing new practices amidst limited resources and changing climate conditions.

Nonetheless, the research highlights the importance of managing this external support carefully. There have been instances where top-down strategies that did not adequately involve local communities resulted in minimal success or even failure. A case in point is an initiative in Zambia’s Kafue Flats that aimed to restore wildlife populations.

Efforts to establish sustainable populations ultimately fell short in part due to the local community’s rejection of new governance frameworks imposed by outside groups. This highlights the necessity for external organizations to collaborate closely with local stakeholders and honor existing social structures and governance.

Lambin and Jahel stress the significance of sustaining progress over time. Some interventions they examined had promising outcomes at first, but struggled later as external funding diminished or local engagement decreased. The researchers point out that it is crucial to incorporate long-term resilience into these initiatives, making sure that local communities can continue to thrive.

Efforts have been made to maintain and enhance improvements without relying on continuous external assistance. In Namibia, certain community wildlife management organizations, referred to as conservancies, have begun to earn sufficient profits to sustain their operations over the long term.

This study offers valuable insights from previous experiences in Africa that can aid in refining the design, management, and oversight of initiatives focused on reversing land degradation and promoting sustainable land use practices.

“Reversing environmental decline is achievable,” stated Lambin. “The essential factor is establishing lasting interventions that are driven by local communities.”

Focus on including issues related to poverty, underpinned by solid governance frameworks and collaborative partnerships among various stakeholders.
