The Pangani basin in the North of Tanzania is increasingly water-stressed. Climate change is impacting regular rainfall patterns, and catchment degradation is leading to reduced water flows. Meanwhile,  water demand is increasing due to population growth and economic development. Additionally, decreasing water quality, partly due to pollution from agricultural practices, and poor water, sanitation and hygiene (WASH) conditions is affecting the health of riverain communities. Combined, these dynamics are reducing the resilience of riverain communities to consequences of climate change, as well as to global shocks such as COVID-19.

Partnerships for healthy catchments

NatuReS Tanzania supports partnerships in the Usa and Weruweru sub-catchments, which are part of the Kikuletwa catchment in the Pangani basin. To improve communities’ resilience towards climate change and health hazards like the current pandemic, NatuReS supports the Pangani Basin Water Board in working closely with the local government, community organizations and businesses to address the water-related challenges in the sub-catchments.

Currently, three initiatives are improving water conservation in the upper parts of the sub-catchments and increasing the efficiency of water use in the lower parts of the sub-catchments, particularly within irrigation furrow systems. By doing so, these initiatives are addressing environmental risks impacting the health of the river and of its inhabitants.

Initiatives aimed at improving resilience of ecosystems and communities

Maintaining healthy forests remains one of the most effective ways to ensure the health of catchment ecosystems. A tree-tracking app, developed in cooperation with the NGO Greenstand, supports communities willing to reforest degraded areas. Communities are trained to track the growth of the trees they are planting and receive a monetary compensation for their efforts. Additionally, the app serves as a communication channel to inform communities on preventive measures against COVID-19.

Most inhabitants of the sub-catchments are smallholder farmers. The Tanzanian civil society organization Shahidi wa Maji is conducting a WASH assessment within the DOMIKWA and MKUFI irrigation furrows in the Kikuletwa catchment to detect risk sources for deteriorating quality of water meant for human consumption. Pollution hotspots will be identified and farmers’ WASH situation – both in the furrows and at their homes – will be assessed following the Alliance for Water Stewardship (AWS) standards. Based on the results, Shahidi wa Maji will be able to implement the necessary actions needed to improve WASH conditions both at the farms and at peoples’ homes.

Finally, Rikolto, an international NGO, is training 1,026 smallholder farmers within the Usa and Weruweru furrows on good agricultural practices, such as pesticide and fertilizer use. The aim is to improve water use efficiency and reduce water pollution within the furrows. Reducing water risks such as scarcity and pollution will turn the furrows into a healthy source of water and therefore enhance the communities’ resilience.

Together against external shocks

Water scarcity and poor WASH, as spotlighted by the current COVID-19 pandemic, are posing serious challenges to local communities in the Usa and Weruweru sub-catchments in Northern Tanzania. Enabling communities to improve their resilience to such shocks is essential. Therefore, the WASH assessment will provide guidance on how to increase the health of local populations; trainings on agricultural best practices will decrease the health risks users of the furrows are currently facing; and afforestation will contribute to better absorb climate change-induced shocks in the long-term.

Good Agricultural Practices (GAP) within South Africa’s uMhlathuze Water Stewardship Partnership

“The story for us started in 2015 when there was a national drought that crippled everything”, says Nomzamo Kheswa. She is the head of the Siyazisiza Trust, an organization established in 1987 to support small-scale farmers in improving their livelihoods, food security and the environment. South Africa is already severely impacted by droughts. In the coming years, they are projected to become even more frequent due to climate change. Small-scale farmers like Phumzile Ntuli are suffering from prolonged droughts as their crops and fruits are not growing. Butternuts, which she and other members of the Qalekhaya Cooperative are usually harvesting around October and selling at markets until January, simply did not survive the excessive heat this year.

Under the uMhlathuze Water Stewardship Partnership, Local Good Agricultural Practices (LocalG.A.P.) trainings were conducted to eight members of the Syazisiza Trust, certifying them as GlobalG.A.P. Farm Assurers. With the knowledge gained, they were able to train 50 local small-scale farmers from the uMhlathuze Catchment in LocalG.A.P. best practices.

The trainings enable farmers to improve their water management and to achieve better harvests, while also strengthening their economic position, as the certification opens up markets for them.

Strengthening Collaboration: LuWSI CEO Breakfast and partnership signing event in Lusaka

Water crises are one of the major global risks for the coming decade, ranked third to have the strongest impact on economies and societies alike (Global Risks Report, 2020). But what does this mean for businesses in Zambia?

Across much of the country, factories, mines, farms, and industries are noticing how water stress is hitting their bottom lines and jeopardizing their business models. Lusaka is particularly under threat as groundwater becomes more polluted and depleted, and plans are drawn up for the use of water from the Kafue River.

Responding to this, the Lusaka Water Security Initiative (LuWSI) hosted a CEO breakfast on Wednesday, November 24th. This event, supported by NatuReS Zambia and WWF Zambia, brought together industry representatives, the Mayor of Lusaka, Her Worship Ms Chilando Chitangala, and the Guest of Honour, Zambia’s Minister of Water, Development and Sanitation, Hon. Mike Mposha MP. They discussed how Lusaka’s water challenges can be addressed to the benefit of the city’s economy and its citizens. The Minister emphasized the importance of water security and the need to ensure the protection of the country’s natural resources.

In the spirit of partnerships as promoted by LuWSI, WWF Zambia and GIZ Zambia’s Water and Energy Cluster signed a relationship agreement as part of the event. The agreement aims to strengthen the cooperation between WWF and GIZ on the protection of Zambia’s natural resources and the implementation of green principles, such as supporting LuWSI to protect and enhance water security in Zambia’s capital. It also offers new prospects for a distinctive relationship between the two parties on the following; 

● Water security: Develop a long term strategy for Lusaka’s water security.

● Private sector engagement: Identify and concretise areas of joint action through a clearly defined strategic plan.

● Project portfolio development: Facilitate the development of bankable projects, nature-based solutions, and city resilience initiatives.

The signing of the relationship agreement comes at a time when there is an urgency for increased action towards natural resources management and stewardship, as Zambia’s natural assets are threatened by degradation and extinction. This brings a heightened need for collaborations such as these for collective and impactful action.
